Data from: Work stress and metabolic syndrome in police officers. A prospective study

Objective: The aim of this longitudinal study was to evaluate the association between occupational stress and metabolic syndrome (MetS) in a rapid response police unit. Method: Work-related stress was continuously monitored during the 5-year period with both the Demand-Control-Support (DCS) and the Effort-Reward Imbalance (ERI) models. Blood pressure, body mass index (BMI), waist circumference, triglycerides, HDL-cholesterol, and fasting blood glucose were measured at baseline in January 2009, and in January 2014. 234 out of 290 police officers (81%) completed the follow-up. Results: The majority of police officers had high stress levels. At follow-up, police officers in the highest quartile of stress had significantly higher mean levels of triglycerides, and lower levels of HDL-cholesterol than their colleagues in the lowest quartile. Police officers with high stress had an increased adjusted risk of developing MetS (aOR = 2.68; CI95% = 1.08–6.70), and hypertriglyceridemia (aOR = 7.86; CI95 = 1.29–48.04). Demand and Effort were significant predictors of MetS. Conclusion: Our study supports the hypothesis that work-related stress induces MetS, particularly through its effects on blood lipids. Future longitudinal studies with continuous monitoring of stress levels will definitively confirm this hypothesis.研究目的：本纵向研究旨在评估快速反应警务单位中职业应激与代谢综合征（Metabolic Syndrome, MetS）之间的关联。 研究方法：在为期5年的研究周期内，采用需求-控制-支持模型（Demand-Control-Support, DCS）与付出-回报失衡模型（Effort-Reward Imbalance, ERI）对工作相关应激进行持续监测。分别于2009年1月（基线）与2014年1月测量研究对象的血压、体重指数（Body Mass Index, BMI）、腰围、甘油三酯、高密度脂蛋白胆固醇（HDL-cholesterol）及空腹血糖水平。原招募的290名警务人员中，最终有234人（占比81%）完成了后续随访。 研究结果：大部分警务人员存在较高水平的应激。随访阶段，处于应激最高四分位组的警务人员，其甘油三酯平均水平显著高于最低四分位组的同事，而高密度脂蛋白胆固醇水平则更低。存在高应激的警务人员发生代谢综合征的校正后风险显著升高（校正比值比（adjusted Odds Ratio, aOR）=2.68；95%置信区间（95% Confidence Interval, 95%CI）=1.08–6.70），并发高甘油三酯血症的校正后风险同样升高（aOR=7.86；95%CI=1.29–48.04）。需求维度与付出维度均为代谢综合征的显著预测因子。 研究结论：本研究支持“工作相关应激可诱发代谢综合征”这一假说，尤其通过影响血脂水平实现该效应。未来开展持续监测应激水平的纵向研究将进一步验证该假说。
