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 understand the prevalence of central obesity and its risk factors for obesity in Guangxi urban and rural residents and provide a scientific basis for disease control. Methods Using random cluster sampling method in each stage, 4 counties of Nanning, Qinzhou, Hezhou, Hechi and 4 prefectures of Tiandi, Bama, Jingxi and Xincheng were selected, and 2 towns / towns were drawn from each city and county. 6 neighborhood committees / administrative villages. The questionnaires were used to obtain the basic personal information of urban and rural residents aged 18 years and above. The data of waist circumference were obtained through physical examination with SPSS13.0 software. Results A total of 8,560 urban and rural residents aged 18 and over were surveyed, with an average waist circumference of 73.60 ± 9.49cm, of which 75.99 ± 9.38cm in male was significantly higher than that in female (71.77 ± 9.15cm). Urban residents (76.53 ± 10.03cm) Rural (70.57 ± 7.81cm). The prevalence of central obesity in Guangxi was 16.90%, of which 25.28% in urban areas was significantly higher than that in rural areas (8.23%) (P <0.01). There was no significant difference between male and female in urban and rural areas. The prevalence of heart obesity is on the rise. Logistic regression model showed that the risk factors of centripetal obesity in urban residents were age, average annual income and light manual labor, while the risk factors for rural residents were Han nationality, high average annual income, highly educated and light manual labor. Conclusion Guangxi residents, especially urban dwellers central obesity epidemic seriously, strengthen health education, especially the prevention and treatment of obesity extensive popularization of high-income and light manual workers in urban and rural residents, to enhance physical activity or exercise and by other means is Important measures to prevent and treat centripetal obesity.
