广东省2002年成人超重、肥胖流行病学特征分析

目的 了解广东省成年人超重肥胖的流行特征,确定预防控制的重点人群和地区。方法 运用多阶段随机整群抽样方法,抽取大城市、中小城市、2类农村各3个区(县)、1类农村4个县,每个县(区)抽取2个街道(乡)、6个居委,共540户,用面对面询问调查获得≥18岁居民个人基本情况,体检获取体重、身高数据。结果 共调查≥18岁成年人15 130人,体重指数均值为22.03±3.38,男性(22.06±3.37)与女性(21.98±3.40)比较差异无统计学意义,城市(23.06±3.53)与农村(21 08±2.94)比较差异有统计学意义。超重、肥胖的粗患病率分别为16 8％和1.8％,年龄标化患病率分别为15.0％和1 7％。超重粗患病率城市(24 8％)高于农村(9.4％),男性(17 5％)高于女性(16 2％);肥胖粗患病率城市(3.1％)明显高于农村(0 7％),男性(1 8％)与女性(1.7％)之间差异无统汁学意义。超重、肥胖的影响因素主要为体力活动、家庭收入、性别、年龄、吸烟与城乡。结论 广东省超过六分之一成年居民超重和肥胖,已经成为一个重要的公共卫生问题,必须采取平衡膳食、增加体力活动与健康教育等措施进行综合防治。

Study on the epidemiological characteristics of overweight and obesity among population eighteen and over in Guangdong province in 2002

OBJECTIVE: To describe the epidemiological characteristics of overweight and obesity among people aged 18 and over in Guangdong province in 2002, and to identify the populations and regions under high risk. METHODS: Cross-sectional survey was used through sampling on multi-stage randomized clusters. Data of socialeconomic status were collected by face-to-face interview. Data on weight and height was obtained through physical check-ups. RESULTS: A sample size of 15 130 people and the mean body mass index (BMI) was 22.03 +/- 3.38 with no significant difference between males and females. However the significant difference was seen between cities and rural areas. The crude prevalence rate of overweight and obesity were 16.8% and 1.8%, and the age-adjusted rate were 15.0% and 1.7%, respectively. The crude rate of overweight in cities (24.8%) and males (17.5%) were higher than that in rural areas (9.4%) and females (16.2%). The crude rate of obesity in cities was seen higher than that in the rural areas, but not significantly different between females and males. The results of logistic regression analysis showed that the major risk factors influencing overweight would include household income, age, gender, smoking habits, physical exercises and location of residence. CONCLUSION: About one sixth of the citizens in Guangdong province were considered to be overweighted and obesive had become an important public health problem. Integrated measures must be taken for prevention and control.
