北京市朝阳区12所监测点校学生营养状况调查分析

Investigation and analysis of nutritional status of students from 12 primary and secondary school in Chaoyang district,Beijing

目的了解北京市朝阳区中小学生营养情况,为营养不良、超重及肥胖综合防治工作提供依据。方法对北京市朝阳区12所监测点校(包括小学5所,中学5所,职业中学2所)10661名在校中小学生进行身高和体重测量,同时收集营养状况资料。体重低于1985年全国体质调研确定的7～22岁身高标准体重值的90%为判定为营养不良。依据《中国学生超重、肥胖BMI筛查标准》判定超重和肥胖。结果 12所点校营养不良患病率为17.70%,超重患病率为12.48%,肥胖患病率为21.27%。女生营养不良患病率高于男生,男生超重和肥胖患病率高于女生,营养不良和营养过剩患病率随年级上升而增高。与2006年12所监测点校中小学生营养状况比较,学生营养不良率和超重率有所下降,但肥胖率明显上升。结论朝阳区12所学校的中小学生营养不良、营养过剩的患病率都处于较高水平,且与性别和年级有关,今后应有针对性地采取措施加以改善。
