甘肃榆中农村居民体力活动与其他心血管病危险因素的关系研究

目的探讨农村体力活动与其他心血管病危险因素的关系。方法利用甘肃榆中农村心血管病及危险因素的流行病学调查资料进行统计分析。体力活动量采用梅脱-小时（MET-hr）为定量单位。结果本次研究有效问卷1087份。男女间文化程度和年收入差异有统计学意义（P〈0.01）,肥胖率和吸烟率有显著差异（P〈0.01）。劳作、家务、运动和交通体力活动中,农民的劳作日均活动量最高。高血压人群及中心性肥胖人群的劳作和日均活动总量分别低于非患病人群,差异有统计学意义（P〈0.01）,交通和休闲运动量与各类心血管病危险因素之间的差异均无统计学意义（P〉0.01）。调整人口学特征后,劳作活动量和日均体力活动总量的增加对中心性肥胖有保护作用,运动量越大保护作用越强（P〈0.05）;同时高强度的劳作或增加日均活动总量对超重/肥胖有保护作用（P〈0.05）。结论我国不同社会人口学特征的居民运动情况不同,国内应针对不同人群的体力活动特点制定指南,引导我国居民积极参加体力活动。

Relationship between Physical Activity and Other Cardiovascular Disease Risk Factors of Rural Residents of Yuzhong Coun -try in Gansu

Objective To analyze the relationship between physical activity （PA ） and other risk factors of cardiovascular disease.Methods By using data of cardiovascular disease and its risk factors from epidemiological study which was carried out in Yuzhong Country in Gansu.Using the quantitative unit MET-hr to measure the energy expenditure of PA.Results There are 1087 valid questionnaires of the study.Education levels and annual income between male and female had a significant difference （ P〈0.01） ,so did obesity rates and smoking rates.During toil ,housework ,excises and traffic of PA ,the average daily energy expenditure of farmers reached highest.Work PA and daily total PA energy expenditure of hypertension group and central obesity group were lower than people who were not sick ,there was a statistical significance （ P〈0.01 ）.The difference between the traffic and leisure-time PA energy expenditure and the risk factors of cardiovascular disease had no statistical significance （ P〉0.05 ）.After adjusting for demographic characteristics ,the increase of work PA or daily total PA energy expenditure can protect people from central obesity ,more PA energy expenditure makes more protective effect （ P〈0.05 ）.In the meantime ,the high-strength work or increase of daily total PA energy expenditure can protect people from overweight/obesity （ P〈0.05 ）. Conclusions Chinese residents with different social demographic distribution have different PA characters ,a PA guideline for different crowds should be formulated to guide Chinese residents to take part in physical activities positively.
