摘要:
目的 探讨山西大同煤矿集团男性工人体力活动度对血脂异常的影响。方法 采用两阶段整群分层抽样方法抽取大同煤矿共3 656名男性矿工进行调查。血脂异常的诊断依据中国成人血脂异常防治指南，并分为四种情况。体力活动度的评价依据国际体力活动问卷处理指南的要求分为低、中、高三水平。结果 在男性煤矿工人中，体力活动低、中、高三水平所占比例分别为17.65%、15.18%和67.17%。在控制了混杂因素（年龄、体质指数（body mass index，BMI）、腰臀比、吸烟情况、饮酒情况等）的情况下，与低体力活动水平相比，高体力活动水平与高甘油三酯（triglyceride，TG）水平（OR=0.72，95%CI：0.58~0.90）、低高密度脂蛋白（high density lipoprotein，HDL-C）水平（OR=0.68，95%CI：0.55~0.84）、高低密度脂蛋白（low density lipoprotein，LDL-C）水平（OR=0.68，95%CI：0.55~0.85）、血脂异常A（OR=0.68，95%CI：0.55~0.84）、血脂异常B（OR=0.67，95%CI：0.54~0.84）、血脂异常D（OR=0.44，95%CI：0.20~0.97）均有关联（均有P<0.05），而中体力活动水平与血脂异常的发生关联均无统计学意义（均有P>0.05）。结论 研究结果表明，适当高强度的体力活动是男性煤矿工人血脂异常的保护因素。
Abstract:
Objective To investigate the association between dyslipidemia and physical activity among male coal miners of Shanxi Province in China. Methods 3 656 coal miners in Datong Coal Mine Group were collected by two-stage stratified cluster sampling method.The definition of dyslipidemia was based on the Chinese guidelines on treatment and prevention of dyslipidemia in adults. Self-reported physical activity was obtained with the international physical activity questionnaire (IPAQ) and categorized into three tertiles of low-, moderate- and high-activity levels. Results The percentages of individuals with vigorous, moderate, and low physical activity (PA) levels were 17.65%, 15.18% and 67.17% respectively. After adjustment of the potentially confounding effects of age, body mass index (BMI), waist-to-hip ratio (WHR), tobacco use, alcohol use, vigorous PA was associated with elevated TG(OR=0.72,95% CI:0.58-0.90), decreased HDL-C(OR=0.68,95% CI:0.55-0.84), elevated LDL-C(OR=0.68,95% CI:0.55-0.85), one abnormality (OR=0.68,95% CI:0.55-0.84),two abnormality(OR=0.67,95% CI:0.54-0.84)and four abnormality(OR=0.44,95% CI:0.20-0.97)(all P<0.05). However, moderate PA did not affect the different types of dyslipidemia(all P>0.05). Conclusions Our study suggested that appropriate high intensity of physical activity is a protective factor for dyslipidemia of male mine workers.
