目的了解吉林省西部贫困县6~15岁中小学生生长发育和营养状况,为进一步改善贫困县中小学生生长发育和营养状况提供科学依据。方法 2013年在吉林省大安市、通榆县、镇赉县随机抽取了30所学校,对在校的6~15岁5 837名学生进行身高、体重的测量并进行描述性分析。结果从2013年吉林省西部贫困县6~15岁中小学生不同年龄、性别身高、体重均值、身高和体重发育曲线图上看,男生在各个年龄段身高和体重的均值均普遍高于女生。营养不良的学生有1 039名(占17.80%),超重学生有855名(占14.65%),肥胖学生有706名(占12.10%)。结论目前吉林省西部贫困县中小学生生长发育符合一般规律,男、女生身高、体重均随年龄增长而逐年增加。男生营养不良率显著高于女生,男、女生超重率基本接近,男生肥胖率稍高于女生,应进一步采取有效措施以减少营养不良、控制超重与肥胖的发生率。
Objective To understand the growth and nutritional status of primary and secondary school students aged 6-15 years in poor counties of western Jilin Province and to provide scientific evidence for further improving the growth and nutritional status of primary and secondary school students in poor counties. Methods In 2013, 30 schools were randomly selected from Da’an City, Tongyu County and Zhenlai County in Jilin Province. The height and weight of 5,837 students aged 6-15 years were measured and analyzed descriptively.
