Obesity On Rise In Rural China: Study

2016-05-02T03:57:00.000-07:00

BEIJING: A new study has highlighted rising obesity rates among children in rural China.

The study, published in the latest issue of the European Journal of Preventive Cardiology, found children and adolescents in the countryside of Shandong province to be much fatter in 2014 than they were in 1985.

It was based on a survey tracking nearly 28,000 students from rural schools in Shandong, a predominantly agricultural area, over 29 years. The students were aged from seven to 18 when they were surveyed.

Some 17.2 per cent of the boys surveyed in 2014 were obese, while the rate was only 0.03 per cent in 1985, according to the thesis, reports Xinhua.

The obesity rate among girls was 9.11 per cent in 2014, while in 1985 the percentage was 0.12 per cent.

Meanwhile, the proportions of overweight boys and girls climbed to 16.35 per cent and 13.91 per cent respectively in 2014.

In 1985, the proportions were 0.74 per cent and 1.45 per cent, said Zhang Yingxiu, one of the co-authors of the thesis.

He said the increase was even more apparent among children aged from seven to 12.

The study used a cut-off of Body Mass Index (BMI) -- the ratio of weight-to-height squared -- to define overweight and obesity.

Thousands of hospital admissions in York due to obesity

2016-05-02T03:55:00.001-07:00

NEARLY twice as many women than men from York have been admitted to hospital with problems related to obesity, figures have revealed.

Over the last year there were 3,155 incidents where people from the Vale of York were taken into hospital where obesity was the main or secondary reason - of these 2,035 were female patients and 1,120 were male.

This represents 896 admissions per 100,000 of the population in the York area.

There were 440,288 admissions to England's hospitals in 2014/15 where obesity was the main reason for a person being admitted or was a secondary factor. The figure is the highest on record and is more than ten times higher than the 40,741 recorded in 2004/5.

The report, from the Health and Social Care Information Centre (HSCIC), also showed that the proportion of adults now regarded as morbidly obese is growing.

Those who have a body mass index (BMI) of 40 or more has more than tripled since 1993, affecting two per cent of men and four per cent of women in 2014.

Izzi Seccombe, community well-being spokeswoman for the Local Government Association, which represents councils that have a responsibility for public health, said: "These are extremely worrying figures that illustrate the scale of the challenge we face in the fight against obesity.

"But the problem will only get worse unless we take urgent action, with the number of obese adults in the country forecast to soar by a staggering 73 per cent to 26 million people over the next 20 years.

"The fact that the number of admissions for children has more than doubled since 2004/5 underlines why it is vital that the Government uses its forthcoming childhood obesity strategy to address what is now one of the major health dangers of the 21st century.

"Obesity leads to serious health conditions later on in life, such as heart disease, cancer and diabetes, and is costing the NHS around £5 billion a year.

"Councils have long been calling for action to tackle obesity, such as clearer labelling of sugar content, calorie counts on menus, and sugar reduction in soft drinks. We cannot delay tackling this issue any longer."

In the East Riding of Yorkshire there were 1,557 incidents when obesity was a factor in a person being admitted to hospital, in Harrogate there were 1,245, in Hambleton, Richmondshire and Whitby there were 446 and in Scarborough there were 695.

In each instance more women were admitted than men.

Nationally, the majority of hospital admissions with a primary diagnosis of obesity were for female patients with 6,630 incidents, equating to 73 per cent, compared to 2,500 for men.

Women underwent 76 per cent of bariatric surgery procedures performed by the NHS during 2014-15, according to the latest figures released by the Health and Social Care Information Centre (HSCIC).

During 2014-15, 6,030 bariatric surgery procedures were recorded in total with 4,590 procedures carried out on women, compared to 1,440 for men.

Obesity a new threat to South Africa

2016-04-30T06:37:00.001-07:00

Durban - South Africa has an obesity epidemic on its hands - and it is women who are most at risk to develop diseases associated with carrying too much weight.

Researchers at Priceless (Priority Cost Effective Lessons for System Strengthening South Africa) SA, a research unit hosted by Wits University School of Public Health, have warned that obesity-related diseases now rival HIV/Aids as the biggest killer of South Africans.

According to Professor Karen Hofman, director at Priceless, 13.8 percent of deaths in South Africa are caused by Aids complications, while 13.1 percent of deaths are now caused by “non-communicative lifestyle diseases” such as heart disease and diabetes.

“South Africa has the highest prevalence of obesity in sub-Saharan Africa,” Hofman said.

According to the 2012 SA National Health and Nutrition Examination, 39 percent of women are obese, compared to 11 percent of the male population.

KZN Health MEC Sibongiseni Dhlomo said: “Being obese is detrimental to good health.”

Dhlomo said the country faced a danger as current efforts were concentrated on fighting HIV and tuberculosis, while non-communicable diseases were the new threat.

“Already in this country some 66 percent of women and 33 percent of men are overweight and our health care facilities are observing an increase of relatively young people suffering from high blood pressure, coronary heart diseases, diabetes and several types of cancer,” he said.

KZN MEC for Arts, Culture, Sport and Recreation Ntombikayise Sibhidla-Saphetha said the government was concerned about the scourge of obesity in the country.

“A study conducted last year by the University of North West School of Biokinetics, Recreation and Sport Science, revealed that nearly two-thirds of the South African population is overweight.

“The study further revealed that 70 percent of women are overweight. It also highlighted the fact that South African children have the third-highest obesity rate in the world,” she said.

Combating obesity was one of the department’s aims because obesity contributed significantly to the decline of the country’s health status, Sibhidla-Saphetha said.

To help residents get healthy, the department would be investing R41.3 million in two core programmes that promote active and healthy lifestyles.

“Over the last four years, the department has installed 44 outdoor gyms in local municipalities. In 2016/17, the department will install a further 11 outdoor gyms,” she said.

“Fitness instructors trained by the department will service the centres with daily programmes of aerobics, jogging, walking, nutritional tips as well as assistance on the use of the gym equipment,” she said.

Shane Norris, researcher professor at Wits who works for the African Centre on Obesity Prevention, has spent 26 years studying the root causes of obesity.

For poor children, two healthy meals a day can keep obesity away

2016-04-14T02:43:00.001-07:00

Schoolchildren who receive a nutritious lunchtime meal are less likely to be overweight or suffer from childhood obesity. And those who receive both breakfast and lunch are three times less likely to suffer this fate.

Tackling childhood obesity is important because it may result in adult obesity and these children developing non-communicable diseases such as diabetes, hypertension and heart disease later in life.

Obesity is not necessarily driven by overeating, as is commonly thought. Children can also develop obesity when they are eating poor quality and inexpensive food that may be high in fats and refined carbohydrates.

Globally, about 44 million children are overweight or obese. In South Africa, about 28% of children between the ages of two and 14 are overweight or obese.

Lizzy Buchan: Stop blame and get back to basics to fix obesity

2016-04-14T02:42:00.001-07:00

These are words no parent wants to hear, as no one wants to be told that they are responsible for their child suffering from a plethora of health problems as well as pervasive social stigmas.

It was the implication earlier this week, when Glasgow University published an interesting piece of research exploring the link between certain parenting practices and child obesity levels.

The scientists found mothers with lower levels of formal education were more likely to have children with a higher Body Mass Index (BMI), as their families were more likely to eat in front of the TV or to have less formally structured meal times.

While this might not be shocking to some, it shows we have gone so far in the wrong direction that we need to learn the basics all over again.

Obesity is the new cancer, the buzz issue that everyone is talking about.

Scientists have uncovered links to a threatening list of illnesses, including cancer, heart disease, and neurological and psychological conditions such as dementia and depression.

We know that Scotland has a major problem with expanding waistlines, as around 65 per cent of adults were found to be overweight or obese in 2014.

Link between obesity, kidney cancer identified

2016-04-14T02:36:00.002-07:00

Receptors for leptin, a protein hormone, may be associated with tumor recurrence in patients with renal cell carcinoma (RCC), providing further understanding about molecular links between obesity and RCC tumor formation and prognosis, according to a study at The University of Texas MD Anderson Cancer Center.

The findings are being presented April 18 at the annual meeting of the American Association of Cancer Research (AACR) in New Orleans.

The leptin receptors, called LEPR, were found to be hypermethylated in tumors in a study involving 240 newly diagnosed and previously untreated Caucasian RCC patients. Methylation is a mechanism by which cells control gene expression and both hypomethylation and hypermethylation are known to play roles in silencing of tumor suppressor genes or over-expression of oncogenes in cancer cells. LEPR was one of 20 obesity-related genes that the research team examined.

"Obesity is an established risk factor for RCC with more than 40 percent of these cases attributed to excessive body weight," said Xifeng Wu, M.D., Ph.D., professor of Epidemiology and principal investigator for the study. "Growing evidence suggests that obesity also may be associated with the prognosis of RCC. The molecular mechanism LEPR and two other genes, NPY and LEP, are involved in RCC tumorigenesis. LEPR methylation in tumors is associated with recurrence in RCC patients and thus, LEPR may provide a functional link between obesity and RCC."

The study evaluated the association between methylation of 20 obesity-related genes and RCC. For the discovery portion of the study, 63 tissue pairs of RCC tumors and normal adjacent tissues from the surrounding kidney were used. An additional 177 pairs were included for the validation component of the study.

The patients were mostly males with an average age of 59 years who had never smoked. Most of the patients had clear cell RCC and were at the earliest stage of disease.

"Patients were classified into high- and low-LEPR methylation groups," said Julia Mendoza-Perez, Ph.D., a visiting scientist of Epidemiology at MD Anderson who presented the findings at AACR. "We found that high LEPR methylation was associated with a significantly higher risk of tumor recurrence."

The results were adjusted by age, gender, pathologic stage of disease, grade, smoking status, body mass index, hypertension and histology.

"In addition, high LEPR methylation in tumors was associated with more advanced tumor features, such as high pathologic stage, high grade, and clear cell RCC histology," said Wu.

The researchers add that future studies are needed to further understand the biology underlying the ties between LEPR methylation and RCC recurrence.

Soaring obesity in women causes womb cancer cases to DOUBLE in just 20 years

2016-04-13T06:55:00.003-07:00

Obesity is fuelling a massive jump in the number of women suffering womb cancer.
The number of patients diagnosed with the disease has almost doubled in 20 years, correlating alongside a spike in womb cancer rates, Cancer Research UK warned.
From 1993 to 1995, around 19 women in every 100,000 developed womb cancer in the UK, rising to 29 women in every 100,000 by 2011-13 (the most recent figures available).
Around 9,000 women are now diagnosed with womb cancer every year in the UK - up from around 4,800 new cases a year 20 years ago.
It kills around 2,000 women every year.
Professor Jonathan Ledermann, director of the Cancer Research UK and UCL Cancer Trials Centre, said: 'It's worrying that womb cancer cases are going up so sharply.
'We don't know all the reasons why. But we do know that about a third of cases are linked to being overweight so it's no surprise to see the increases in womb cancer cases echo rising obesity levels.
'The good news is that thanks to research and improved treatments, survival has improved.
'In the 1970s, almost six in 10 women diagnosed with the disease survived for at least 10 years. Now almost eight in 10 women survive.
'But we need more research to understand the biology of the disease better and to know more about how it is caused so that we can improve the treatment of these women as well as preventing more cases.'
In January, Cancer Research UK warned that almost 700,000 more people could develop cancer in the next 20 years due to being overweight or obese.

We are NOT to blame for being OBESE, claims health expert

2016-04-11T04:07:00.002-07:00

I DON'T know exactly what qualifies as a "superhuman effort" but when I hear that phrase I tend to picture someone who has dived into a freezing lake to save a child or lifted a heavy car off a crushed cyclist. I don't think of someone who refuses an extra helping of pudding.

In the mind of the Government's health tsar Susan Jebb, however, that mere act is sufficient to elevate someone to the status of Batman, Spiderman or some other fantasy hero. "Obesity has increased greatly over the last few decades," she said last week.

"That is not a national collapse of willpower. It's something about our environment that has changed. You need in some cases a superhuman effort to reduce your food intake."

It is not our fault if we get fat, she asserts. We should blame those dastardly food companies and retailers who line the high streets with burger shops and put sweets next to the tills.

How can we be expected to walk past such temptation without succumbing? I don't doubt that some people find it harder than others to know when to stop eating. However there is ultimately only one cause of obesity: not slow metabolism, not faulty genes but eating too much.

Unless you are being force-fed like a goose bred for paté de foie gras it is entirely within your control to monitor what you eat. Virtually all packaged food now comes with details of calorific content so it is not too hard to work out if you are exceeding a sensible daily intake of food.

If Jebb, who also serves as professor of diet and population health at the University of Oxford, thinks we can't be expected to have the willpower to turn down sugary snacks, from what else does she think we should be absolved: drinking too much, taking drugs, shoplifting, groping women on the Tube, hitting people we don't like? Civilised life becomes utterly impossible if we are not expected to exercise willpower and control our behaviour. Exercising selfrestraint is not superhuman, it is just human.

THE trouble is, it isn't only Jebb who seems to have this view of humans as pathetic creatures who bear no responsibility for their own actions. It has now become the ruling philosophy of many policy-makers and do-gooders.

In 2013 the American Medical Association voted to classify obesity as a disease against the advice of an expert panel that had warned of the consequences.

Activity equivalent calorie labelling to fight obesity

2016-04-11T04:04:00.005-07:00

If pictorial warnings on tobacco products help in effectively conveying the harsh reality of the effects of tobacco and increase the awareness among users and potential users, there is a strong case to change the way food items are labelled, too. Instead of merely stating that a particular food item has a certain amount of calories, there is a greater possibility that people would change their eating habits if the labels contained information on equivalent exercise required to burn the calories contained in the food item, the Royal Society of Public Health, U.K., says.

“Giving consumers an immediate link between foods’ energy content and physical activity might help to reduce obesity,” Shirley Cramer, Chief Executive at the Royal Society of Public Health writes in The BMJ.

There is little information that current information found on food and drink packaging, including “traffic light” labelling, has any effect on consumption behaviour. “Packaging should not only provide nutritional information but should also help people to change behaviour,” she notes.

The Royal Society for Public Health has called for the introduction of “activity equivalent” calorie labelling. The prominent pictorial icons placed alongside existing front-of-pack information would contain symbols that show the minutes of several different physical activities that would be required to burn off the calories individuals consume in the product. “The aim is to prompt people to be more mindful of the energy they consume and how these calories relate to various activities in their everyday lives, to encourage them to be more physically active,” she writes. “Those from lower socioeconomic societal groups often have lower nutritional knowledge, and health literacy. Information on food must be presented in a medium that can be understood by all sections of society, regardless of social class or economic situation. It is known that consumers understand symbols more easily than numeric information which suggests activity equivalent calorie labels may provide an easier reference for people less able to decipher current front-of-pack labels,” the RSPH position paper notes.

For example, instead of merely stating that a can of carbonated drinks contains 138 calories, mentioning that it would take a person of average age and weight about 26 minutes of walk to burn 138 calories contained in the can of drink will be direct and more effective. “Given its simplicity, activity equivalent calorie labelling offers a recognisable reference that is accessible to everyone,” Cramer writes.

“Initial studies show that this approach can change behaviour by reducing intake or modifying choice” she notes. The Royal Society of Public Health got important and positive feedback from people on activity equivalent labelling. For instance, public polling by the society has shown that almost half (44 per cent) of people find current front of pack information confusing. And almost two-third (63 per cent) of people said they would support the introduction of activity equivalent labelling. After viewing activity equivalent calorie labels compared with current traffic light front-of-pack information, people were over three times more likely to indicate that they would undertake physical activity. A body of evidence indicates that even a modest increase in physical activity can have significant health benefits. For instance, a brisk 20 minute walk each day has the potential to lower a person’s risk of premature death by between 16-30 per cent.

Centre planning sugar tax to fight obesity, diabetes

2016-04-07T04:35:00.003-07:00

NEW DELHI: Junk food and sugar-sweetened beverages will soon be taxed higher and subjected to tougher advertising norms. The government plans these measures to control the growing incidence of diabetes in the country.
The health ministry and the central food safety regulator are working on a proposal to cut consumption of unhealthy food and beverages, mainly among children. For, these are known to be responsible for the burden of diabetes cases and obesity. An inter-ministerial consultation on the matter took place in February .
"There is a serious effort to control non-communicable diseases, mainly diabetes and cancer. We have a multisectoral action plan and consultations are on with different ministries," a senior health ministry official said. The ministry is compiling feedback from ministries and will refer the proposal to the finance ministry and the PMO, he added.
There is consensus among ministries and departments on the need for stringent measures to contain the rising disease burden right from childhood, the official said.
Diabetes Foundation and Centre of Nutrition and Metabolic Research estimates show the annual per capita consumption of sugar-sweetened beverages in the country rose from around 2 litres per head in 1998 to 11 litres per head in 2014.

More Evidence That Obesity Is A Global Catastrophe In Slow Motion

2016-04-07T04:35:00.001-07:00

Sometimes it is harder to see things that move in slow motion. Perhaps if the global obesity epidemic moved any faster, it would garner an emergency response similar to Ebola, Zika, and other infectious disease epidemics that have gripped the world in recent years. As two recent studies published in The Lancet and authored by the Non-Communicable Disease (NCD) Risk Factor Collaboration have re-emphasized, the sheer magnitude of the global obesity epidemic dwarfs those of most other epidemics. The impact may be much greater as well, accounting for many more deaths (over 3.4 million a year) and more costs (over $2 trillion a year). My colleague Larry Cheskin, MD, Associate Director of our Global Obesity Prevention Center (GOPC) at Johns Hopkins University and Associate Professor at the Johns Hopkins Bloomberg School of Public Health, describes the global obesity epidemic as “a catastrophe happening in slow motion.” But has everyone around the world responded as if the obesity epidemic were indeed a catastrophe ?

One of the Lancet studies confirmed that obesity and overweight is a growing problem worldwide, even in countries that in the past have had problems with lack of food. The study analyzed the change in body mass index (BMI) from 1698 studies among 19.2 million adults in 200 countries from 1975 to 2014. The researchers found that during this time period the average BMI increased from 21·7 to 24·2 kg/m2 among men and from 22·1 to 24·4 kg/m2 among women. Average BMIs among men were lowest (21·4 kg/m2) in central Africa and south Asia and highest in 29·2 kg/m2 in Polynesia and Micronesia. Among women, average BMIs were lowest (21·8 kg/m2) in south Asia to and also highest (32·2 kg/m2) in Polynesia and Micronesia. During the same time period, obesity prevalence more than tripled from 3·2% to 10·8% among men and more than doubled (6·4% to 14·9%) among women. By comparison, the prevalence of people are underweight, presumably from lack of enough food, decreased from 13·8% to 8·8% among men and 14·6% to 9·7% among women.

The other Lancet study showed a substantial worldwide increase in diabetes since 1980 by analyzing 751 studies that included nearly 4·4 million people. As the study’s senior author Professor Majid Ezzati form Imperial College explained,“obesity is the most important risk factor for type 2 diabetes and our attempts to control rising rates of obesity have so far not proved successful. Identifying people who are at high risk of diabetes should be a particular priority since the onset can be prevented or delayed through lifestyle changes, diet or medication.” The study found that between 1980 and 2014, diabetes prevalence more than doubled from 4·3% to 9·0% among men and climbed by over 50% from 5·0% to 7·9% among women. This corresponded to the number of adults with diabetes worldwide nearly quadrupling from 108 million to 422 million. In 2014, northwestern Europe has the lowest diabetes rates. Polynesia and Micronesia has the highest (affecting nearly a quarter of adults), followed by Melanesia and the Middle East and north Africa. While not all diabetes cases are related to obesity, obesity is a major risk factor for the more common type of diabetes, Type II or adult-onset diabetes. And diabetes can have devastating health consequences such as heart problems, kidney disease, and stroke. (Of course, obesity can result in many other health problems besides diabetes.)

Obesity surgery linked to reduced pain, improved mobility

2016-04-07T04:34:00.003-07:00

Many severely obese patients have less pain and better mobility in the first few years after weight loss surgery, a U.S. study suggests.

Researchers followed more than 2,200 obese patients who had weight loss surgery. After one year, 58 percent of them reported less pain and 77 percent said they had better physical function.

By three years, the proportion of patients still reporting improvements in pain and physical function dropped significantly to 49 percent and 70 percent, respectively.

Patients did, however, report consistent improvements in walking ability at one and three years, and those who started with knee and hip problems also reported lasting pain reductions and mobility increases around these joints.

While surgery remains more effective for lasting weight loss than alternatives such as dieting and exercising, the findings suggest that not all surgical patients will get the same results, said lead study author Wendy King, a public health researcher at the University of Pittsburgh.

The amount of weight lost after the surgery, rather than the type of surgery, was "consistently related to improvements in pain and function," King said by email.

Globally, 1.9 billion adults are overweight or obese, according to the World Health Organization. Obesity increases the risk of heart disease, diabetes, joint disorders and certain cancers.

Global obesity is pushing the world to a 'crisis point'

2016-04-06T05:22:00.000-07:00

For the first time, the world has more obese people than underweight, a new report says. The change presents health challenges for the two fattest countries — China and the U.S. — and threatens to divert resources from countries where low body weight remains a problem, the BBC says.

Reporting on the study published April 2 in The Lancet, the BBC said the number of obese people had risen from 105 million in 1975 to 641 million in 2014, creating a global "crisis point," according to lead researcher Majid Ezzati, a professor in the School of Public Health at Imperial College London.

If trends continue, a fifth of the world's population will be obese by 2025, researchers said.

"Global obesity prevalence will reach 18 percent in men and surpass 21 percent in women; severe obesity will surpass 6 percent in men and 9 percent in women. Nonetheless, underweight remains prevalent in the world's poorest regions, especially in south Asia," the report said.

The World Health Organization blames increased consumption of high-fat, energy-dense foods, coupled with inactivity caused by modern lifestyles, for the rise in obesity.

Children aged under five eating too many calories increasing risk of obesity says study

2016-04-06T05:21:00.003-07:00

University College London study also found under fives eat too much salt and miss out on vitamins

Children under the age of five are eating too many calories, too much salt and missing out on vitamins, experts have warned.

High intake of protein and too many calories overall raises their risk of obesity, while too much salt could “set taste preference for the future” and put them at risk of high blood pressure and strokes in later life.

Researchers also urged parents to follow Government guidelines on giving children up to the age of five supplements to boost levels of iron and vitamin D.

Their study found youngsters were woefully lacking in essential vitamins.

The study, published in the British Journal of Nutrition, examined data for 2,336 children from one of the UK’s largest dietary datasets for toddlers, the Gemini twin birth cohort.

There are More Obese People in the World Than Underweight People, New Study Reveals

2016-04-04T04:31:00.003-07:00

A new study revealed that over 640 million people globally are considered to be obese, now outnumbering people who are considered to be underweight.
The study, published in the journal The Lancet, analyzed population-based studies that had measured the height and weight of adults aged 18 years and older.

The research used 1,698 population-based data sources, with more than 19.2 million adult participants, consisting of 9.9 million men and 9.3 million women, from 186 countries.
The study applied a Bayesian hierarchical model to the data to estimate trends from 1975 to 2014 in mean body mass Index (BMI).
BMI, as per a Reuters report, is an indication of whether a person is of healthy weight. This index is computed by dividing the weight in kilogram and height in meter squared.
A BMI score of over 30 is considered to be obese, while a score above 40 is considered to be morbidly obese.
The researchers discovered that in the past four decades, the number of obese people in the world has increased from 105 million in 1975 to 641 million in 2014.

Poor diet and lack of exercise accelerate the onset of age-related conditions in mice

2016-04-04T04:31:00.000-07:00

Could an unhealthy diet and lack of exercise be making you age faster? Researchers at Mayo Clinic believe there is a link between these modifiable lifestyle factors and the biological processes of aging. In a recent study, researchers demonstrated that a poor diet and lack of exercise accelerated the onset of cellular senescence and, in turn, age-related conditions in mice. Results appear today in Diabetes.

Senescent cells are cells that contribute to diseases and conditions associated with age. Researchers from the Mayo Clinic Robert and Arlene Kogod Center on Aging found that exercise prevents premature senescent cell accumulation and protects against the damaging effects of an unhealthy diet, including deficiencies in physical, heart, and metabolic function, equivalent to diabetes.

"We think at both a biological level and a clinical level, poor nutrition choices and inactive lifestyles do accelerate aging," says Nathan LeBrasseur, Ph.D., director of the Center on Aging's Healthy and Independent Living Program and senior author of the study. "So now we've shown this in very fine detail at a cellular level, and we can see it clinically. And people need to remember that even though you don't have the diagnosis of diabetes or the diagnosis of cardiovascular disease or the diagnosis of Alzheimer's disease today when you're in midlife, the biology underlying those processes is hard at work."

In the study, researchers introduced mice to either a normal, healthy diet or a diet that they termed a "fast food diet" -- one that was high in saturated fat and cholesterol, along with a sugar-sweetened beverage. Mice on the fast food diet showed harmful changes in health parameters, including body weight and composition, increasing their fat mass by nearly 300 percent over the course of about four months. The fat mass accumulated largely in the midsection surrounding internal organs, an area that is often linked to a number of diseases related to obesity.

More obese people in the world than underweight, says study

2016-04-02T02:43:00.000-07:00

There are now more adults in the world classified as obese than underweight, a major study has suggested.
The research, led by scientists from Imperial College London and published in The Lancet, compared body mass index (BMI) among almost 20 million adult men and women from 1975 to 2014.
It found obesity in men has tripled and more than doubled in women.
Lead author Prof Majid Ezzat said it was an "epidemic of severe obesity" and urged governments to act.
The study, which pooled data from adults in 186 countries, found that the number of obese people worldwide had risen from 105 million in 1975 to 641 million in 2014.
Meanwhile the number of underweight people had risen from 330 million to 462 million over the same period.
'Crisis point'
Global obesity rates among men went up from 3.2% in 1975 to 10.8%, while among women they rose from 6.4 % in 1975 to 14.9%.
This equates to 266 million obese men and 375 million obese women in the world in 2014, the study said.
The research also predicted that the probability of reaching the World Health Organization's global obesity target - which aims for no rise in obesity above 2010 levels by 2025 - would be "close to zero".

We now live in a world in which more people are obese than underweight, major global analysis reveals

2016-04-02T02:41:00.001-07:00

In the past 40 years, there has been a startling increase in the number of obese people worldwide -- rising from 105 million in 1975 to 641 million in 2014, according to the most comprehensive analysis of trends in body mass index to date.

The age-corrected proportion of obese men has more than tripled, and the proportion of obese women has more than doubled since 1975. At the same time, the proportion of underweight people fell more modestly--by around a third in both men and women.

In the past 40 years, there has been a startling increase in the number of obese people worldwide--rising from 105 million in 1975 to 641 million in 2014, according to the most comprehensive analysis of trends in body mass index (BMI) to date, published in The Lancet.

The age-corrected proportion of obese men has more than tripled (3.2% to 10.8%), and the proportion of obese women has more than doubled (6.4% to 14.9%) since 1975. At the same time, the proportion of underweight people fell more modestly--by around a third in both men (13.8% to 8.8%) and women (14.6% to 9.7%).

Over the past four decades, the average age-corrected BMI increased from 21.7kg/m² to 24.2 kg/m² in men and from 22.1kg/m² to 24.4 kg/m² in women, equivalent to the world's population becoming on average 1.5kg heavier each decade. If the rate of obesity continues at this pace, by 2025 roughly a fifth of men (18%) and women (21%) worldwide will be obese, and more than 6% of men and 9% of women will be severely obese (35 kg/m² or greater).

However, excessively low body weight remains a serious public health issue in the world's poorest regions, and the authors warn that global trends in rising obesity should not overshadow the continuing underweight problem in these poor nations. For example, in south Asia almost a quarter of the population are still underweight, and in central and east Africa levels of underweight still remain higher than 12% in women and 15% in men.

"Over the past 40 years, we have changed from a world in which underweight prevalence was more than double that of obesity, to one in which more people are obese than underweight," explains senior author Professor Majid Ezzati from the School of Public Health at Imperial College London, London, UK. "If present trends continue, not only will the world not meet the obesity target of halting the rise in the prevalence of obesity at its 2010 level by 2025, but more women will be severely obese than underweight by 2025."

He adds, "To avoid an epidemic of severe obesity, new policies that can slow down and stop the worldwide increase in body weight must be implemented quickly and rigorously evaluated, including smart food policies and improved health-care training."

Weight loss and health: 4 tips more useful than 'eat less, move more' from nutrition experts

2016-03-31T02:07:00.001-07:00

What nutrition experts want you to know about eating healthily - including the foods they would not touch

Navigating the avalanche of information available on how to stay stay fit and healthy can feel exhausting, and make the urge to tuck into a friendly-looking kebab or doughnut even more tempting.

And while the mantra "eat less, move more" is a helpful starting point, it leaves many questions unanswered.

We have asked four diet and nutrition experts for the most important factors to remember when trying to lead a healthy lifestyle, to stop you from desperately grasping at the latest diet fad every few months.

If it sounds too good to be true, it probably is

If the premise of a miracle diet falls apart under the weight of a little scrutiny, it probably won't work in the long term. Necking a bottle of wine, eating chips and gorging on chocolate to stay healthy and lean long-term? Unlikely.

Aisling Pigott, a dietician and spokeswomen for the British Dietetics Association (BDA), stresses: “There is no such thing as a magic answer when it comes to a healthy diet.

"We live in a world where we are so keen for ‘quick fixes’ and fast solutions. This is not helpful for people trying to tackle the complex relationships and routines they may have with food, eating and health."

Beans, Chickpeas May Help With Weight Loss: Study

2016-03-31T02:06:00.005-07:00

WEDNESDAY, March 30, 2016 (HealthDay News) — Beans, chickpeas, peas, lentils: Humble foods that may pack a punch for weight loss, Canadian researchers report.

A new analysis of data from 21 clinical trials on these foods — collectively known as “pulses” — finds that they can help dieters feel full, and shed unwanted pounds.

“Though the weight loss was small, our findings suggest that simply including pulses in your diet may help you lose weight, and we think more importantly, prevent you from gaining it back after you lose it,” study lead author Russell de Souza, a researcher at St. Michael’s Hospital in Toronto, said in a hospital news release.

One expert wasn’t surprised by the findings.

“These types of legumes are some of the most underappreciated foods around,” said Dana Angelo White, a nutritionist and assistant professor of sports medicine at Quinnipiac University in Hamden, Conn.

“They are full of fiber, protein, vitamins and minerals,” she noted. “It makes sense they would help facilitate weight loss and reduce cholesterol when eaten regularly.”

The Canadian team also noted that pulses have a “low glycemic index” — meaning that they break down slowly in the digestive tract. As such, they can be consumed instead of animal protein or unhealthy fats at mealtimes.

The trials included in the new analysis involved a total of 940 adults. When participants started eating one serving (3/4 cup) of pulses a day, they lost an average of 0.75 pounds over six weeks without making any special effort to avoid other types of foods, the researchers said.

According to de Souza’s team, prior research has shown that eating bean, lentils and other pulses makes people feel fuller.

That’s key to weight loss — 90 percent of weight loss programs fail, due in part to the influence of hunger and food cravings, according to de Souza.

“This new study fits well with our previous work, which found that pulses increased the feeling of fullness by 31 per cent, which may indeed result in less food intake,” he said.

These foods also appear to help lower blood levels of “bad” LDL cholesterol, he added.

Antonella Apicella, an outpatient dietitian at Lenox Hill Hospital in New York City, said the study, “supports the notion that foods such as beans, lentils, chickpeas and dry peas may reduce body fat and may contribute to weight loss, even if calories were not restricted.”

She agreed that pulses do seem to help people feel fuller, sooner, and the fiber these foods contain “may reduce the absorption of fat.”

Obesity on the rise in Mumbai: Survey

2016-03-30T07:01:00.001-07:00

MUMBAI: A study has shown how Mumbaikars are under the dual threat of obesity and hypertension.

A survey by the Indus Health Plus on 35,662 people, who came for preventive health checks, found that 15% were under the threat of obesity and related complications. About 35-40% between the age group of 25-45 years were leading a sedentary lifestyle, had easy access to high-calorie processed food and overdependence on gadgets, all of which put them at a high risk of becoming obese. About 20% had both hypertension and obesity.

"There is sharp decline in physical activities among population residing in Mumbai, which doubles the risk for obesity. Trends have shown people are prone to increased waist circumference which makes them prone to co-morbid diseases like hypertension, diabetes, stroke, etc. In youngsters suffering with obesity, the chances of developing heart diseases and diabetes increase by 3-4%," said Amol Naikawadi, preventive healthcare specialist at the Indus Health Plus.

Only 3-4% of the surveyed population ate a healthy diet that included salads and green vegetables. Around 30% of those who were obese between the age groups of 35-45 years had complaints of joint pain, feeling of laziness and tiredness.
A senior doctor said that obesity is a consequence of complex interaction of genetics, diet metabolism and physical inactivity. It can give rise to several health problems, including hypertension, diabetes, heart diseases, and osteoarthritis. "Desk jobs combined with lack of exercise has increased the incidence of obesity in the city," the doctor said. According to the WHO, a third of the world's population is overweight and one-fifth are obese.

Obesity is one of biggest problem in U.S. – Beaumont Health News

2016-03-29T04:40:00.003-07:00

Obesity is still rising among American adults, despite more than a decade of public-awareness campaigns and other efforts to get people to watch their weight, and women have now overtaken men in the obese category, new government research shows.

For the last several years, experts thought the nation’s alarming, decades-long rise in obesity had leveled off

But the Centers for Disease Control and Prevention said in a report Thursday that the obesity rate has climbed to nearly 38 percent of adults, up from 32 percent about a decade earlier.”This is a striking finding” and suggests that a situation that was thought to be stable is getting worse, said William Dietz, an obesity expert at George Washington University.
Experts said they had no explanation for why the rate appears to be rising.The report, based primarily on a survey conducted in 2013-14, also found the obesity rate was significantly higher for women, at 38 percent, compared with 34 percent for men. The rates for men and women had been roughly the same for about a decade.

Obesity is considered one of the nation’s leading public health problems. Until the early 1980s, only about 1 in 6 adults was obese, but the rate climbed dramatically until it hit about 1 in 3 around a decade ago.

“Clearly it is a huge issue in Philadelphia,” said Cheryl Bettigole, the city health department’s director of chronic disease prevention. She was surprised by the new national numbers and did not have equivalent new data for the city. “We see obesity everywhere these days, but we see high rates in poor neighborhoods and communities of color.”

Obesity rates in the more affluent suburban counties tend to be lower.

Philadelphia has tried to reduce obesity through a wide-ranging series of initiatives in recent years, from working with corner stores to increase their selection of fresh fruits and vegetables to a sort of fresh-foods supplement to food stamps. Participants can spend $5 at a farmers’ market and get back $2 worth of “Philly Food Bucks” for the purchase of fresh produce.

While obesity rates among adults in the city have continued to rise, there is some early evidence of success among children

Obesity rates among schoolchildren dropped by 6.3 percent between the 2006-07 and 2012-13 school years, and even more among severely obese and African American children.The new CDC figures come from a regular government survey that involves not only interviewing people about their girth but also actually weighing them. Because of that, it is considered the gold standard for measuring the nation’s waistline.

However, it has about 5,000 participants each year – far fewer than some other federal surveys that ask about weight. Generally, it can be harder to draw reliable national conclusions from a smaller survey.

Like Philadelphia, the federal government has undertaken campaigns to encourage people to eat better and exercise. New federal rules have been adopted to remove artificial trans fats from grocery store foods and to require chain restaurants to post calorie counts, though those have not gone into effect yet.

Meanwhile, soda consumption has dropped in recent years, and fast-food chains have adopted healthier menus.

The widening gap between men and women seems to be driven by what’s happening among blacks and Hispanics, said the study’s lead author, the CDC’s Cynthia Ogden.

Obesity rates for white men and white women remain very close

But for blacks, the female obesity rate has soared to 57 percent, far above the male rate of 38 percent. The gender gap is widening among Hispanics, too – 46 percent for women, 39 percent for men.

The report also looked at obesity in children but did not see much change. For people ages 2 to 19, the rate has been holding at about 17 percent over the last decade or so.

Health officials have been especially focused on obesity in children

A CDC report last year noted a possible glimmer of hope: a decline in obesity among children ages 2 to 5. Their rate had fallen to about 8 percent in the 2011-12 survey, down from 14 percent a decade earlier.

In a piece of good news, the new, 2013-14 report suggests that the decline among toddlers was real and not a statistical fluke. The rate was found to be holding pretty much steady around 9 percent.

The CDC measures obesity by calculating body mass index, a ratio of weight to height. For adults, a BMI of 25 to 29.9 is overweight, and 30 or higher is obese. According to CDC definitions, a 5-foot-10 man is overweight at 174 pounds and obese at 209.

Obesity rates have more than doubled in adults and children since the 1970’s (National Center for Health Statistics, 2009). While recent estimates suggest that the overall rates of obesity have plateaued or even declined among some groups, obesity is widespread and continues to be a leading public health problem in the U.S. (Ogden et al., 2014; Robert Wood Johnson Foundation, 2015; Wen et al., 2012). In addition, severe obesity is a serious and increasing problem among children, adolescents, and adults (Fryar et al., 2012; Skinner & Skelton, 2014). Plus, substantial disparities exist based on demographics (e.g., race-ethnicity, gender), geographic region, and socioeconomic status (SES). (See the section on the Relationship Between Poverty and Obesity for more information on SES disparities.)

Adult Overweight and Obesity in the U.S.

More than two-thirds of U.S. adults are overweight or obese (Ogden et al., 2014). In general, rates of overweight and obesity are higher for African-American and Hispanic women than Caucasian women, higher for Hispanic men than Caucasian and African-American men, higher in the South and Midwest, and tend to increase with age (Ogden et al., 2014; Gregg et al., 2009; Sherry et al., 2010). Research also shows that the heaviest Americans have become even heavier the past decade (Beydoun & Wang, 2009).

Racial-Ethnic Disparities
Recent national data show that 82.0 percent of Black women and 77.2 percent of Hispanic women are overweight or obese compared to 63.2 percent of White women (Ogden et al., 2014). In addition, over half of Black women are obese (versus 37.1 percent of Black men and 32.8 percent of White women) (Ogden et al., 2014). Extreme obesity continues to be higher among women (8.3 percent) than men (4.4 percent), especially among Black women who have more than double the rates of extreme obesity as White and Hispanic women (16.4 percent versus 7.4 percent and 7.6 percent) (Ogden et al., 2014). Rates of overweight or obesity are higher for Hispanic men (78.6 percent) compared to Black men (69.2 percent) and White men (71.4 percent) (Ogden et al., 2014).

Bulging babies: 3 or more antibiotics before age 2 may spur obesity

2016-03-29T04:40:00.001-07:00

For decades, farmers have known that the quickest way to fatten up young, healthy livestock is to feed them antibiotics—the drugs will even plump animals on a diet. It’s unclear why the practice, called growth promotion, works. Scientists have a range of hypotheses, including that the drugs may kill off gut microbes that compete for calories or knock back mild infections that would otherwise take energy to fight off. Whatever the answer, one thing is certain: growth promotion spurs drug-resistance in bacteria. And with the rise of infections from such superbugs in people—a major threat to public health—the practice is now squarely discouraged.

Yet, despite the long-held practice in farms, researchers are just beginning to harvest data on whether the drugs have the same effect on human babies in clinics. So far, much of the data—but not all—shows some concerning similarities.

Looking at a population-representative sample of nearly 22,000 children in the United Kingdom, researchers found that giving children three or more courses of antibiotics within the first two years of life modestly increased the likelihood that they would be obese at age four. The study, being published in Gastroenterology, follows several smaller studies that hinted at such a connection, particularly for antibiotics used in the first six months of life.

“Collectively, we’re starting to recognize that maybe there’s more to avoiding antibiotics than just the antibiotic resistance problem,” gastroenterologist Frank Scott, of the University of Colorado-Denver, told Ars. “No doubt that that’s probably the biggest issue facing us right now,” he added. Still, Scott said it’s important to look at these subtler, potentially life-long health effects.

Past studies looking into this issue found similar effects on weight gain in childhood and beyond, but these often relied on parents' recall of how many antibiotics their children took, used much smaller pools of kids, or showed mixed results. Scott and colleagues set out to conduct a cleaner, larger study that relied on comprehensive electronic medical records that followed kids for years.

Of the 21,714 children with complete records in the study, about 64 percent were given antibiotics in the first two years of life. The researchers then adjusted the data for factors known to influence childhood obesity, including maternal and sibling obesity, maternal diabetes, mode of delivery (C-section, for example), socioeconomic status, year and country of birth, and urban dwelling.
