贵阳市某城区中老年人群超重和肥胖流行病学调查

Epidemiological Investigation of Overweight and Obesity of Middle-aged and Elderly Adults in Guiyang

目的:调查贵阳市某城区中老年人群超重及肥胖流行状况。方法:采用随机整群抽样的方法选择在贵阳市云岩区居住5年以上40~80岁的普通汉族居民共10 017人为研究对象,进行问卷调查、体格检查,计算体质量指数(BMI),比较不同年龄段男性女性超重、肥胖、中心性肥胖比例,观察不同运动量、睡眠状况及文化程度对象的肥胖率。结果:不同年龄段男性超重率、肥胖率及中心性肥胖率比较,差异无统计学意义(P>0.05);随着年龄的增长,女性超重率、肥胖率及中心性肥胖率逐渐增高,差异有统计学意义(P<0.01);在40~69岁年龄段,男性的超重率高于同年龄段女性(P<0.05),40~49岁年龄段男性肥胖率高于同年龄段女性(P<0.01),50岁以上年龄段女性中心性肥胖率高于同年龄段男性(P<0.01);有规律中等强度运动人群、受教育程度较高的人群肥胖率较低(P<0.01)。结论:贵阳市中老年人群超重率、肥胖率及中心性肥胖率与西南、西部部分地区研究结果相似,中年男性、老年女性、缺乏运动及受教育程度低的人群是肥胖防治的重点人群。

Objective： To investigate the epidemiological characteristics of overweight,obesity and central obesity of middle-aged and elderly adults in Guiyang,China. Methods： The Yunyang District of Guiyang City,Guizhoyu China was selected as the research site. A total of 10 017 Han residents of over 40 years old who lived in Guiyang for more than 5 years were selected. A randomized cluster sampling method was used to conduct questionnaires and physical examinations. Results： The rate of overweight of the male population was higher than that of the female（ P〈0. 05）. There was no significant difference in the obesity rate between the male and the female,but the prevalence of female central obesity was higher than that of the male（ P〈0. 01）. In the male population,the obesity rate in the group of aged 40 - 49 was higher than that in the same aged group of the female（ P〈0. 05）. The prevalence of overweight,obesity,and central obesity in the female population increased with the growth of age（ P〈0. 01）,and the prevalence of central obesity in the female groups of aged over 50 were significant higher than that in the male groups of the same age（ P〈0. 01）. People with regular moderate-intensity exercise and higher education had lower rates of obesity. Conclusion： The prevalence rate of overweight,obesity,and central obesity in the middle-aged and elderly population in Guiyang City is similar to some ares of southwest and western vegions. Middle-aged men,older women and people with lack of exercise,and of lower education levels are the focus of obesity prevention.
