Obesity is a priority public health concern in Canada and other parts of the world. The study primarily aims at assessing the role of self-perceived work and life stress on obesity among working adults in Canada.
The study was conducted based on a total of 104,636 Canadian adults aged 18 and above, extracted from the 2017-2018 Canadian Community Health Survey (CCHS) data. We used a mixed-effect logistic regression model to determine the possible association between two stress variables and obesity, controlling for other variables in the model. The random effect term accounts for the correlation among the observations from the same health region.
A total of 63,815 adult respondents (aged 18 and above) who were working during the 12 months prior to the survey were studied. Of those, 18.7% were obese based on their self-reported BMI > =30.0 kg/m. More than two-thirds of the respondents reported that their stress level is a bit stressful to extremely stressful. The results of multivariable mixed-effect logistic regression showed that the odds of obesity were 1.432 times (95% CI: 1.248-1.644) among those who reported extremely work-related stress, compared to those who had no work-related stress. Perceived life stress was not significantly associated with obesity risk among working adult population, after adjusting other factors.
The study concluded that obesity among Canadian adults is 18.7% of the working adult population being obese. Given the reported high prevalence of stress and its effect on obesity, the findings suggested improving social support systems, individual/group counseling, and health education focusing on work environments to prevent and manage stressors and drivers to make significant program impacts.
肥胖是加拿大和世界其他地区优先关注的公共卫生问题。该研究主要旨在评估自我感知的工作和生活压力对加拿大在职成年人肥胖的影响。
该研究基于从2017 - 2018年加拿大社区健康调查（CCHS）数据中提取的总共104,636名18岁及以上的加拿大成年人进行。我们使用混合效应逻辑回归模型来确定两个压力变量与肥胖之间的可能关联，并对模型中的其他变量进行控制。随机效应项考虑了来自同一健康区域的观察值之间的相关性。
共研究了在调查前12个月内工作的63,815名成年受访者（18岁及以上）。其中，根据自我报告的体重指数（BMI）≥30.0 kg/m²，18.7%的人肥胖。超过三分之二的受访者表示他们的压力水平处于有点压力到极度压力之间。多变量混合效应逻辑回归结果显示，与没有工作相关压力的人相比，报告有极度工作相关压力的人肥胖几率是其1.432倍（95%置信区间：1.248 - 1.644）。在调整其他因素后，感知到的生活压力与在职成年人群的肥胖风险没有显著关联。
该研究得出结论，加拿大成年人中的肥胖率为在职成年人口的18.7%。鉴于所报告的高压力患病率及其对肥胖的影响，研究结果建议改善社会支持系统、个人/团体咨询以及针对工作环境的健康教育，以预防和管理压力源及驱动因素，从而产生重大的项目影响。
