男性煤矿工人高体力活动水平与不同定义下血脂异常水平的关联性

High physical activity is associated with an improved lipid profile among male coal miners

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,HDLC)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。

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 pre- vention of dyslipidemia in adults. Self-reported physical activity was obtained with the international physical activity ques- tionnaire （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% re- spectively. 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） , de- creased 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 4）. 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 dys- lipidemia of male mine workers.
