2002年广东省成年人向心性肥胖流行特征分析

Analysis on epidemiological characteristics of central obesity of population aged eighteen and over in Guangdong Province in 2002

目的 了解广东省成年人向心性肥胖的流行特征 ,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 ,抽取全省大城市、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 5 4 0户 ,采用面对面询问调查获得 18岁及以上居民个人基本情况 ,体检获取腰围数据。结果 共调查 18岁及以上成年人 15 130人 ,腰围 (WC)为 (75 2 6± 9 6 7)cm ,其中男性 (77 2 4± 9 6 0 )cm ,高于女性 (73 80±9 4 5 )cm ;城市 (77 4 3± 10 11)cm ,高于农村 (73 2 5± 8 78)cm。向心性肥胖的粗患病率为 2 3 9% ,年龄标化患病率为2 1 6 %。男、女性标化患病率分别为 19 6 %和 2 3 1% ,差异有统计学意义 (u =4 92 95 ,P <0 0 5 ) ;不论男女 ,城市患病率 (2 8 5 % ,2 6 4 % )高于农村 (12 2 % ,19 6 % )。男性向心性肥胖的主要影响因素为体力活动、城乡、家庭人均收入、年龄、婚姻状况、教育程度、职业和吸烟情况 ;女性向心性肥胖的主要影响因素为体力活动、年龄、职业、家庭人均收入、教育程度和民族。结论 根据抽样结果推算 ,广东省 1/ 5以上的成年人患向心性肥胖 ,体力活动是最重要且可以改变的危险因素。必须尽快加强向心性肥胖的研究和防治工作。

Objective To describe the epidemiological characteristics of central obesity of population aged 18 and over in Guangdong province in 2002,and to identify the high-risk population and region.Methods The cross-sectional survey study population was a representative sample of Guangdong province obtained through multi-stage randomized cluster sampling.The data of socioeconomic status were collected by face-to-face interview,and waist circumference(WC) was measured by physical examination.Results The sample size was 15?130,and the mean of WC was(75 26±9 67)cm for all population.For male and city,the mean of WC was higher than that in female and rural.The crude prevalence rate of central obesity was 23 9%,and the age-abjusted rate was 21 6%.The age-adjusted rate in female(23 1%)was higher than that in male(19 6%).No matter sex,it's higher in city than that in rural.Logistic regression indicated that for male,physical activity,residence,household income,age,marital status,education,occupation and smoking status were major risk factors of central obesity.And for female,physical activity,age,occupation,household income,education and ethnicity were major risk factors.Conclusion More than one fifth population aged 18 and over in Guangdong province are centrally obese,and physical inactivity is the most important risk factor which is modified by intervention.It's necessary to enhance research and intervention on central obesity.
