宁夏地区回汉族中小学生超重肥胖流行趋势分析

目的了解宁夏地区2005-2010年回族与汉族不同群体学生超重、肥胖流行趋势,为制定学生肥胖防治措施提供依据。方法使用2005和2010年宁夏地区全国学生体质调研资料的数据,利用中国学龄儿童青少年超重和肥胖体质量指数(BMI)筛查标准,对7～18岁中小学生进行超重、肥胖筛查。结果汉族男生超重率2005年为7.9%,2010年为10.1%;肥胖率2005年为3.8%,2010年为5.1%。回族男生超重率2005年为4.0%,2010年为7.4%;肥胖率2005年为1.9%,2010年为4.7%。汉族女生超重率2005年为5.4%,2010年为5.7%;肥胖率2005年为1.8%,2010年为2.9%。回族女生超重率2005年为4.7%,2010年为5.9%;肥胖率2005年为1.3%,2010年为2.6%。城乡回、汉族7～12岁小学生是超重、肥胖高流行的群体。在控制了年龄、城乡、性别的影响后,2010年学生超重肥胖率高于2005年,汉族学生的超重、肥胖率高于回族学生,差异均有统计学意义(P值均<0.01)。结论宁夏地区城市和农村回、汉族中小学生超重和肥胖均已逐渐进入流行增长期,需要采取综合防治措施控制学生肥胖。
