To explore the relationship between work-related stress and obesity among female shift workers. Additionally, we also aimed to test the interaction between shift work and work-related stress in this association.
A cross-sectional study was conducted among Brazilian female shift workers. Work-related stress was assessed through a demand-control questionnaire (Job Stress Scale). Work-related stress was defined by the presence of high psychological demands and low control at work. The obesity cases were defined as those with a BMI of 30 kg/m2 or more. Multivariate Poisson regression with robust variance was used to obtain the prevalence ratios (PR) and their respective 95 % CI.
A group of industries located in southern Brazil in 2017.
Four hundred and twenty female workers aged 18-59 years.
The overall prevalence of obesity was 30 % (95 % CI: 25·6, 34·4), and the presence of work-related stress was identified in 24 % (95 % CI: 19·9, 28·1) of the sample. We found an indication of interaction between work-related stress and night shift work on obesity (P = 0·026). After adjusting for confounding factors, work-related stress was associated with a 71 % greater probability of obesity (PR = 1·71; 95 % CI: 1·02, 2·87; P = 0·042) among female night shift workers.
In this study, we revealed that exposure to work-related stress and night shift work were associated with obesity among female shift workers. Furthermore, the prevalence of obesity was high among female shift workers.
探讨职业相关应激与女性倒班工人肥胖之间的关系。此外，我们还旨在检验这种关联中倒班与职业相关应激之间的相互作用。
这是一项在巴西女性倒班工人中进行的横断面研究。通过需求-控制问卷（工作应激量表）评估职业相关应激。职业相关应激定义为工作时存在高心理需求和低控制。肥胖病例定义为 BMI 为 30 kg/m2 或以上的人群。采用稳健方差的多变量泊松回归获得患病率比（PR）及其相应的 95%置信区间（CI）。
2017 年，巴西南部的一组工业。
420 名年龄在 18-59 岁之间的女性工人。
肥胖的总体患病率为 30%（95%CI：25·6，34·4），样本中 24%（95%CI：19·9，28·1）存在职业相关应激。我们发现职业相关应激与夜班工作之间存在交互作用的迹象（P=0·026）。在调整混杂因素后，职业相关应激与肥胖的相关性为女性夜班工人肥胖的可能性增加 71%（PR=1·71；95%CI：1·02，2·87；P=0·042）。
在这项研究中，我们揭示了职业相关应激和夜班工作暴露与女性倒班工人肥胖之间存在关联。此外，女性倒班工人的肥胖患病率较高。
