目的了解张掖市甘州区中小学生生长发育及营养现状,探索分析中小学生生长发育中存在的问题,为甘州区中小学生生长发育及营养现状的研究提供相应资料,并为评价相关干预效果提供基础数据。方法整群抽取甘州区12所中小学校共计16 363名学生进行身高、体重测量,按“2000年全国7~22岁城乡汉族学生身高、体重百分位数评价表”和中国肥胖工作组(WGOC)制订的BMI标准筛查超重、肥胖学生,用中国学生体质测量评估体系系统软件对其生长发育及营养状况进行评价。结果甘州区7~17岁各年龄组男、女生平均身高和体重均高于2005年兰州市、甘肃省、全国平均水平,而低于2005年北京市的平均水平。学生营养不良率为19.0%,超重率为10.0%,肥胖率为9.0%;男生营养不良率显著低于女生,而超重率、肥胖率均高于女生。结论甘州区中小学生的生长发育状况良好,但超重率和肥胖率较高,且已进入儿童青少年肥胖高流行阶段,因此,建立规范的监测体系和实施综合措施以积极防治儿童青少年肥胖已刻不容缓。
