摘要
目的 了解广州市城乡中年人群的体力活动状况及其与心血管病主要危险因素的关系。方法 采用整群随机抽样方法调查广州市 35～ 5 9岁城市居民 112 4人及农村居民 10 2 9人 ,按照国家“九五”攻关课题 (编号 96 - 90 6 - 0 2 - 0 1)统一方案、采用标准化方法进行。结果 农村人群中等强度及以上的体力活动时间平均占全天的 2 0 7% ,明显高于城市人群 (7 2 % ) ;农村人民不活动或少活动的时间占全天的 6 0 5 % ,较城市人群 (73 7% )少。农村人群高胆固醇现患率、高密度脂蛋白胆固醇降低率、高血糖现患率和超重率均低于城市人群 ,但吸烟率和饮酒率明显高于城市人群。多元线性回归分析显示 ,不活动和少活动时间对血压升高、血中胆固醇升高、高密度脂蛋白胆固醇降低及体重增加的影响均有非常显著性意义。
Objective To investigate the correlation between physical activity and main risk factors of cardiovascular disease in aged 35～59 population of Guangzhou City. Methods Using random cluster sampling, 1 124 urban residents and 1 029 rural residents were sampled in accordance with the standardization method of the national 'ninth-five' key project. A Multi-linear regression analysis was used to analyze the correlation.Results The average time for heavy and middle physical activity in a day in rural residents(20.7%) was obviously higher than that in urban residents(7.2%); physical inactivity in rural residents(60.5%) was lower than that in urban residents(73.7%). The prevalence of hypercholesterolmia and glycemia, the rate of decreased high density lipid cholesterol and overweight in rural residents were lower than that in urban residents, but the rate of smoking and drinking were higher than that in urban residents. The time of physical inactivity has significant positive correlation with increasing of blood pressure, serum cholesterol and body weight and decreasing of high density lipid cholesterol. Conclusion Physical inactivity tends to increase the risk of cardiovascular disease.
