In the last decades there was an increase in stress at work and its effects on workers' health. These issues are still little studied in the electric utility sector. This study aims to evaluate factors associated with stress at work and to verify its associations with health status among workers of an electric company in São Paulo State, Brazil. A cross-sectional study was conducted with 474 subjects (87.5% of the eligible workers). Data were collected using self-reported questionnaires. A descriptive analysis, a multiple linear hierarchical regression analysis and a correlation analysis were performed. The majority of participants were males (91.1%) and the mean age was 37.5 yr. The mean score of stress level was 2.3 points (scale ranging from 1.0 to 5.0). Hierarchical multiple analyses showed that: regular practice of physical activities (p=0.025) and individual monthly income (p=0.002) were inversely associated with stress level; BMI was marginally associated with the stress level (p=0.074). The demographic characteristics were not associated with stress. Stress at work was significantly associated with physical and mental health status (p<0.001). To improve health of electric utility workers, actions are suggested to decrease stress by remuneration and an appropriate practice of physical activity aiming reduction of BMI.
在过去几十年里，工作压力及其对工人健康的影响有所增加。在电力行业，这些问题仍鲜有研究。本研究旨在评估与工作压力相关的因素，并验证其与巴西圣保罗州一家电力公司工人健康状况的关联。对474名受试者（占符合条件工人的87.5%）进行了一项横断面研究。使用自我报告问卷收集数据。进行了描述性分析、多元线性分层回归分析和相关性分析。大多数参与者为男性（91.1%），平均年龄为37.5岁。压力水平的平均得分为2.3分（范围为1.0至5.0）。分层多元分析表明：定期进行体育活动（p = 0.025）和个人月收入（p = 0.002）与压力水平呈负相关；体重指数与压力水平存在微弱关联（p = 0.074）。人口统计学特征与压力无关。工作压力与身心健康状况显著相关（p < 0.001）。为改善电力行业工人的健康状况，建议采取行动，通过薪酬调整和适当进行体育活动来降低压力，以降低体重指数。
