广西城乡成年居民向心性肥胖流行病学研究

Analysis on epidemiological characteristics and risk factors of central obesity of polulation aged eighteen and more in Guangxi

目的掌握广西城乡居民向心性肥胖流行特征及其发生肥胖的危险因素,为疾病控制提供科学依据。方法运用各阶段随机整群抽样方法,抽取南宁、钦州、贺州、河池市4个市和天等、巴马、靖西、忻城4个县,每个市、县再抽取2街道/乡镇、6个居委会/行政村,采取问卷调查获取18岁及以上城乡居民个人基本情况资料,并通过体检取得腰围数据用SPSS13.0软件进行统计。结果共调查18岁及以上城乡居民8560人,平均腰围为73.60±9.49cm,其中男性(75.99±9.38cm)显著高于女性(71.77±9.15cm);城市居民(76.53±10.03cm)显著高于农村(70.57±7.81cm)。广西居民向心性肥胖标化患病率为16.90%,其中城市(25.28%)显著高于农村(8.23%)(P<0.01);城乡男女之间患病率无显著差别;随着年龄增长向心性肥胖患病率有增长之势。Logistic回归模型显示城市居民向心性肥胖的危险因素有年龄、人均年高收入、轻体力劳动因素,而农村居民危险因素为汉族、高人均年收入、高学历和轻体力劳动。结论广西居民尤其是城市居民向心性肥胖流行严重,加强健康教育,在城乡居民尤其是在高收入和轻体力劳动者中广泛开展防治肥胖症科普宣传,通过锻炼和或其他方式来增强体力活动是防治向心性肥胖的重要措施。

Objective To master the epidemiological characteristics and risk factors of central obesity of population aged eighteen and more in Guangxi, and to provide scientific basis for disease control. Methods According to the multi - stage randomized cluster sampling,the study population were selected from two streets/towns and six residents＇committees/administrative villages respectively from 4 city points（Nanning, Qinzhou, Hechi and Hezhou） and 4 country points （Tiandeng, Bama, Jingxi and Xincheng） in Guangxi. The data of socioeconomic status were collected by face-to-face interview, and waist circumference（WC） was measured by physical examination. The Software SPSS 13.0 was used. Results The sample size was 8 560 people and the mean of WC was 73.60±9.49 cm for all population .For male（75.99±9.38cm） and city（76.53±10.03cm）, the mean of WC was higher than that in female（71.77±9.15cm） and rural（70.57±7.81cm）area. The adjusted prevalence rate of central obesity was 16.90%. The rate in city（25.28 % ） was higher than that in rural area（8.23 % ） （P 〈 0. 01）. The rate was not different in sex. The rate increased as age increased, logistic regression indicated that for city, age, high individual income, light physical activity were major risk factors of central obesity. And for rural, Han nationality, high indi- vidual income, tertiary education, light physical activity were major risk factors. Conclusion The central obesity is prevalent badly in Guangxi and in city specially. To enhance health education and scientific publicity is an important measure for the prevention and treatment of central obesity through exercise and other ways in Guangxi especially in high income and light physical activity population.
