【摘要】 目的了解西安市城区2013年0~6岁儿童超重肥胖发病情况,为制定有效的干预措施提供理论依据。方法采取整群分层抽样的方式,抽取西安市城区0~6岁儿童10 374名。以WHO 2007身高别体重肥胖标准作为诊断超重和肥胖的依据,将2013年西安市城区0~6岁儿童的超重/肥胖率与2005年全国同龄儿童进行比较。结果 2013年西安市城区0~6岁儿童的超重率为16.9%,肥胖率为8.2%。除3岁组与5岁组男童超重率高于女童(χ~2值分别19.696,11.756,P值均<0.01)外,其余年龄段儿童超重率性别差异均无统计学意义;除4~6岁组儿童肥胖率性别差异有统计学意义外,其余年龄组肥胖率性别间差异均无统计学意义。与2005年全国同年龄段儿童相比,西安市2岁和4~7岁儿童超重率均低于全国水平,<1岁和1岁组肥胖率高于全国水平,而西安市0~6岁儿童总体超重率低于全国水平,总肥胖率高于全国水平(P值均<0.05)。5 498名男童超重率为18.3%(1 008名),肥胖率为8.9%(491名);4 876名女童超重率为15.2%(742名),肥胖率为7.3%(358名),男童均高于女童(χ~2值分别为17.898,8.677,P值均<0.01)。西安市男童超重率、女童超重率均低于全国水平(P值均<0.01),西安市男童肥胖率与全国水平比较,差异无统计学意义(P>0.05)。结论西安市城区0~6岁儿童超重、肥胖率处于较高水平,制定预防儿童超重/肥胖的有效干预措施势在必行。更多还原

【Abstract】 Objective To explore the development of overweight and obesity among children in Xi’ an city and suburbs and to provide scientific basis for effective preventive measures. Methods A total of 10 374 children aged 0-6 years old were investigated on prevalence overweight and obesity by using random sampling method, of whom 5 498 were boys and 4 876 were girls. According to WTO weight-for-height standard, the overweight rate of the children aged 0-6 years old in Xi’ an city in 2013 was compared with that in 2005. Results The overweight rate among 0-6 year-old children was 16.87% and the obesity rate was 8.18% in 2013. Except that the overweight rates of boys aged 3 or 5 were higher than that of girls( χ~2= 19.696,11.756,P<0.01), there are no significant differences about the overweight rate of children in other age groups. Compared to children of same age group in 2005,the overweight rates in 2-year-old group and the 4 to 7 year-old group in Xi’ an were significantly lower than their national counterparts in the same age groups, while the obesity rate of was heavily higher than the national level. The 0-6 year-old child obesity rate in Xi’ an city was apparently lower than the national figure, whereas the obesity rate is notably higher than the national level( P<0.05). Among 5 498 boy, 1 008 were overweight with an overweight rate of 18.33% and 491 boys were obese and the obesity rate was 8.93%. Among 4 876 girls, 472 participants were overweight with a overweight rate of 15.21% and 358 participants were obese with its obesity rate of 7.92%. There are more obese boys than overweight girls( χ~2= 17.898,8.677,P<0.01). The overweight rates of boys and girls in Xi’ an were lower than national level( P<0.01). The overweight rate of boys are equal to national level, with no statistical significance( P>0.05). Conclusion The overweight and obesity rates of children aged 0-6 years old are very high in Xi’ an city. Therefore, it is imperative to establish effective interventional strategies to prevent the children from developing overweight and obesity.更多还原
