矿区职工睡眠时间与高血压患病率相关性分析

ASSOCIATION BETWEEN SLEEP DURATION AND HYPERTENSION IN MINE WORKERS

目的探讨矿区职工睡眠时间与高血压的关系。方法采取普查的方法对开滦林南仓矿5772名职工进行健康查体,记录自报睡眠时间,符合研究目的且资料完整的为5425名,其中男性4827名,女性598名,年龄20～79(50.62±13.19)岁。根据自报近2年每晚平均睡眠时间将目标人群分为4个组:<6h、6～(h)、7～(h)、≥8h,分别占总人群的14.2%、26.9%、18.4%、40.4%。每位职工均测量同天同时段3次血压,每次间隔2min,取3次平均值。于查体当日抽取空腹静脉血5ml送检。用Excel2003软件建立数据文件,用SPSS13.0软件进行统计分析。结果各睡眠时间组的高血压患病率存在明显差异,短睡眠时间组高血压的患病率要高于长时间睡眠组,差异具有统计学意义(χ2=145.11,P<0.001)。同时线性趋势检验表明,睡眠时间与高血压患病率存在线性关系(线性趋势χ2=46.50,P<0.001),即睡眠时间越短,高血压患病率越高。应用logistic回归分析,经年龄、血脂、体重指数等因素校正后,睡眠时间对高血压患病率仍有影响。结论睡眠时间与高血压患病率相关,随着睡眠时间的缩短,高血压患病率增高。

Objective To investigate the association between sleep duration and hypertension in mine workers. Methods 5425 subjects received healthy examination in Linnancang mine, male 4827, female 598, aged 20 - 79 （50. 62 ± 13. 19） years old. According to the last 2 years of self- reported average nightly sleep duration, the target population was divided into four groups： 〈6h, 6h-, 7b- ,≥8h, which were 14.2%, 26.9%, 18.4%, 40.4% respectively. The average blood pressure was recorded for 3 times per day,and 5ml fasting venous blood was collected as experimental sampies. Results There was an obvious difference in the prevalence rates of hypertension among the groups of different sleep duration. The prevalence rates of hypertension in short sleep duration was higher than that in long sleep groups, statistically significant differences （X^2 = 145.11,P〈0. 001）. At the same time, the linear trend test showed that there was a linear relationship between sleep duration and hypertension prevalence rate （linear trend X^2 = 46.50,P〈0. 001）. There was the trend of shorter sleep duration with higher prevalence of hypertension. Application of logistic regression analysis showed after correction for other factors such as age, blood lipids, body mass index, and sleep time was still the impact factor of the prevalence rate of hypertension. Conclusion There are associations between sleep duration and the prevalence rate of hypertension, and the shorter sleep duration, the higher prevalence of hypertension.
