Epidemiological survey on simple obesity of children in Zhengzhou city

目的:了解郑州地区肥胖儿童发生情况。方法:对2001年体质调研的5760名中小学生,包括郑州市城区和郊区各2880名,城区和郊区男、女各1440名,进行包括年龄、性别、班级、出生日期、体质量、身高的调查,对结果进行统计分析。结果:城区2879名(1名男主项目填写不全)中小学生超重发生率16.53%,肥胖发生率28.97%,小学生、初中、高中各阶段超重和肥胖发生率无明显差异(χ2=12.31,P>0.25);而男生肥胖发生率明显高于女生(χ2=44.46,P<0.001);郊区2880名中小学生超重发生率17.39%,肥胖发生率13.65%,小学生、初中、高中各阶段肥胖发生率分别为12.15%、14.17%、16.11%,差异显著(χ2=353.42,P<0.005);郊区男女儿童肥胖发生率及肥胖度无明显差异(χ2=0.66,P>0.25);城区中小学生肥胖发生率明显高于郊区(χ2=201,P<0.005),7～10岁儿童单纯性肥胖发生率(28.54%)是1989年(8.23%)的3.47倍(χ2=163.80,P<0.005),其中重度肥胖发生率(4.79%)是1989年(0.43%)的11.14倍。结论:儿童肥胖发生率急剧上升,采取有效措施防治儿童肥胖是当务之急。

AIM:To evaluate the incidence of obesity in children in Zhengzhou city. METHODS:A physical fitness survey, including age, sex, grade, birthday, body mass index and body height, was carried out in 2001 in 5 760 school students, 2880 males and 2880 females, aged 7- 18 years, from the urban and rural areas of Zhenzhou city.RESULTS:The incidence rates of overweight and obesity in 2879 students from the urban of Zhenzhou city were 16.53% and 28.97% respectively, and there was no significant difference in the incidence rates of overweight and obesity among primary, junior high school and senior higher school students ( χ 2=12.31, P >0.25) .However, a significant difference was found in the incidence rate of obesity between the urban boys and girls( χ 2=12.31, P >0.25) . The incidence rates of overweight and obesity of the rural students were 17.39% and 13.65% respectively, and the incidence rates of obesity of primary, junior and senior high schools were 12.15% , 14.17% and 16.11% respectively, with a significant difference χ 2=353.42, P< 0.005, but there was insignificant difference between the rural boys and girls ( χ 2= 0.66, P >0.25) . The incidence rate of obesity of the urban students was significantly higher than that of the rural students(χ 2=201, P< 0.005). The data indicated that the incidence rate of simple obesity of children aged 7- 10 years (28.54% ) was 3.47 times over that in 1989(8.23% ), and the incidence of severe obesity of children aged 7- 10 years( 4.79% ) was 11.14 times over that in 1989(0.43% ).
