BACKGROUND
Little is known about the occupational risk factors for obesity in US firefighters.
METHODS
308 male California firefighters, who participated in a work and obesity project, were chosen. Working conditions were measured with a firefighter-specific occupational health questionnaire. Adiposity was clinically assessed using body mass index (BMI), waist circumference (WC), and body fat percent.
RESULTS
In a multivariate analysis, the prevalence of obesity by all measures was significantly higher (PRs = 3.69-6.03, P < 0.05) in the firefighters who reported seventeen to twenty-one shifts than those who reported eight to eleven shifts in the past month. Prolonged sedentary work was also a risk factor for obesity by BMI (PR = 4.18, P < 0.05). Furthermore, there was a linear dose-response relationship of obesity by BMI and WC with the number of 24-hr shifts and sedentary work.
CONCLUSIONS
Many additional 24-hr shifts and prolonged sedentary work substantially increased the risk for obesity in male firefighters. Am. J. Ind. Med. 59:486-500, 2016. © 2016 Wiley Periodicals, Inc.
背景
关于美国消防员肥胖的职业风险因素，人们了解甚少。
方法
选取了308名参与工作与肥胖项目的加利福尼亚男性消防员。使用特定于消防员的职业健康问卷来测量工作条件。通过体重指数（BMI）、腰围（WC）和体脂百分比对肥胖程度进行临床评估。
结果
在多变量分析中，报告过去一个月有17至21个轮班的消防员，所有测量指标下的肥胖患病率显著更高（PRs = 3.69 - 6.03，P < 0.05），高于报告有8至11个轮班的消防员。长时间久坐工作也是BMI定义的肥胖的一个风险因素（PR = 4.18，P < 0.05）。此外，BMI和WC定义的肥胖与24小时轮班次数和久坐工作之间存在线性剂量反应关系。
结论
大量额外的24小时轮班和长时间久坐工作显著增加了男性消防员肥胖的风险。《美国工业医学杂志》59:486 - 500，2016年。© 2016威利期刊公司。
