Lastly, among non-night workers, decreased hazards were observed for quick returns from afternoon shifts (<11 hours) compared with those with no quick returns. Conclusion Exclusive night work is associated with increased risks of multiple PAD compared to day work, implying an increase in risk of mental disorders among nurses and nurse assistants. by Addo S, Nilsson T, Gustavsson P, Bodin T, Bigert C, Lashari A, Härmä M, Brulin E. doi:10.5271/sjweh.4325]]> http://www.sjweh.fi/show_abstract.php?abstract_id=4325 http://www.sjweh.fi/show_abstract.php?abstract_id=4325 Mon, 07 Sep 2026 14:04:48 +0200 Original article 23 years. We estimated Cox models within each cohort; the main model was adjusted for sex, age, education, and occupational class. Additional analyses examined JS categories (low JS, active, passive, high JS), subgroups by sex and occupational classes, and person-time < and ≥65 years. Results were pooled using random-effects meta-analysis. Relevant published studies were identified for synthesis with our results. Results Over 444 767 person-years, 842 CVD deaths occurred. High JS was associated with CVD mortality [hazard ratio (HR) 1.14, 95% confidence interval (CI) 1.01–1.27], with no evidence of heterogeneity. Results were consistent across JS categories, by sex (men: HR 1.15, 95% CI 1.07–1.23; women: HR 1.11, 95% CI 0.88–1.39), and across person-time <65 years (HR 1.24, 95% CI 0.91–1.67) and ≥65 years (HR 1.10, 95% CI 0.80–1.50). The association was stronger among manual workers (HR 1.25, 95% CI 0.84–1.86). Job demands appeared to contribute more than job control. Four published studies with comparable follow-up but heterogeneous study designs reported estimates consistent with our findings. Conclusions High JS is a long-term predictor of CVD mortality, consistently across sexes and during both working age and after retirement. Workplace redesign to reduce job demands, particularly among manual workers, is warranted within a comprehensive prevention strategy. by Giusti EM, Li X, Veronesi G, Linkohr B, Peters A, Waldenberger M, Borchini R, Cesana G, Li J, Rückert-Eheberg I-M, Ferrario MM. doi:10.5271/sjweh.4322]]> http://www.sjweh.fi/show_abstract.php?abstract_id=4322 http://www.sjweh.fi/show_abstract.php?abstract_id=4322 Wed, 19 Aug 2026 20:47:28 +0200 Original article 52 hours per week. Dental caries was identified from clinical oral examinations performed by licensed dentists. Associations were estimated using generalized estimating equations adjusted for age, gender, and educational level. Subgroup and sensitivity analyses were also performed. Results Long working hours were significantly associated with dental caries (odds ratio 1.024, 95% confidence interval 1.007–1.041). In the subgroup analyses, compared with their respective counterparts, the association between long working hours and dental caries was significantly stronger among women, individuals with a college-level education or higher, and those with proactive oral health behaviors such as dental visits and toothbrushing before sleep. Conclusions Long working hours were independently associated with the risk of dental caries; women and highly educated workers exhibited a stronger association with dental caries. These findings suggest the potential value of integrating oral health strategies into occupational health policies, particularly among more vulnerable subgroups. by Park MY, Ahn J. doi:10.5271/sjweh.4319]]> http://www.sjweh.fi/show_abstract.php?abstract_id=4319 http://www.sjweh.fi/show_abstract.php?abstract_id=4319 Tue, 18 Aug 2026 16:22:32 +0200 Original article adj) 1.18, 95% confidence interval (CI) 1.14–1.22] to PE (RR_adj 1.39, 95% CI 1.31–1.47). Among the dimensions of PE, low income was the strongest contributor (RR 1.44, 95% CI 1.39–1.50), while unstable employment had a modest effect (RR 1.16, 95% CI 1.12–1.20). Conclusion PE is associated with elevated risk of COPD in the Swedish workforce. These findings emphasize the role of employment conditions as a social determinant of respiratory health. by Lundh F, Gunn V, Kreshpaj B, Kvart S, Bodin T, Albin M, Selander J, Ekström S, Wiebert P, Matilla-Santander N. doi:10.5271/sjweh.4318]]> http://www.sjweh.fi/show_abstract.php?abstract_id=4318 http://www.sjweh.fi/show_abstract.php?abstract_id=4318 Tue, 04 Aug 2026 22:33:33 +0200 Original article 3 months) after a SARS-CoV-2 infection. Poisson regression analysis was performed to evaluate the independent and joint effects of night shift work and sleep disturbances including chronic insomnia with risk of long-COVID. Analyses were stratified by sex, body mass index and chronotype. Results During the two-year follow-up, 284 of the 1899 newly infected participants reported long-COVID symptoms. Compared to day workers, night shift workers had 88% higher risk of developing long-COVID [95% confidence interval (CI) 1.29–2.72], after adjusting for potential confounders. The risk further increased among night workers with obesity. Chronic insomnia in the general population was associated with 42% increased risk of long-COVID (95% CI 1.12–1.78). Night workers with chronic insomnia had a 2.7 fold higher long-COVID risk (95% CI 1.60–4.51) compared to day workers without chronic insomnia. Associations persisted in various sensitivity analyses. Conclusions Our findings from a large prospective cohort indicate that night shift work and poor sleep are independently and jointly associated with a higher risk of long-COVID. by Papantoniou K, Espinosa A, Karachaliou M, Lassale C, Castaño-Vinyals G, Harding BN, De Matteis S, Straif K, Alonso-Nogués E, Dobaño C, Moncunill G, Blay N, Iraola-Guzmán S, de Cid R, Garcia-Aymerich J, Kogevinas M. doi:10.5271/sjweh.4317]]> http://www.sjweh.fi/show_abstract.php?abstract_id=4317 http://www.sjweh.fi/show_abstract.php?abstract_id=4317 Thu, 02 Jul 2026 16:47:52 +0200 Original article by Kim K, Kang J, Lim DM, Jang S, Lee Y, Lee YH, Yoon HJ, Yang S, Kim SH, Lee D, Jang WI, Sung H, Kim M-J, Son E, Kim H-S, Lee D, Park HR, Seo S, Kim YH. doi:10.5271/sjweh.4294]]> http://www.sjweh.fi/show_abstract.php?abstract_id=4294 http://www.sjweh.fi/show_abstract.php?abstract_id=4294 Thu, 30 Apr 2026 01:52:12 +0200 Review 2=43.91%], gastrointestinal temperature (MD -0.26°C; -0.52– -0.001; I²=98.13%), skin temperature (MD -1.14°C; -1.85– -0.42; I²=96.56%), and heart rate (MD -7.69 bpm; -11.22– -4.15; I²=73.19%). Egger’s tests suggested possible small-study effects for skin temperature and heart rate but not for core temperatures. Subgroup analyses indicated more consistent benefits with water/ice and PCM garments. Overall certainty ranged from low to very low due to risk of bias, inconsistency, and imprecision. Conclusions Wearable cooling attenuates physiological heat strain and improves thermal comfort, particularly via water/ice and PCM systems. Given high heterogeneity and low certainty, adequately powered, standardized, head-to-head trials are needed. by Sheth A, Viramgami A, Thakor M, Modi B, Bagepally B, Kar A, Ram E, Dave A, Balachandar R]]>
