摘要
目的了解襄樊市低年级小学生身高状况,探索影响儿童身高的相关因素,为制定儿童身高干预策略提供科学依据。方法采用分层整群随机抽样的方法,收集襄樊城区及所辖市县一至三年级小学生身高资料;自编问卷调查身高相关影响因素。结果2 532名7～9岁儿童身高发育特点总体来看,各年龄组男童平均身高高于女童;男女童身高都随着年龄的增加而增长,男童身高增长值平均为5.35cm,女童身高增长值平均为5.85cm,符合儿童生长发育规律;男女童身高都略低于全国同龄平均身高,但无显著性差异(P>0.05)。结论学生身高与遗传和环境因素关系密切,应在生长发育旺盛的小学低年级阶段采取饮食、运动、睡眠、心理干预和疾病治疗等综合措施进行群体干预,促进儿童的生长发育。
Objective： To understand the situation of height development of low-grade pupils in Xiangfan City, to study the impact of children height-related factors, and to provide scientific basis for developing intervention strategies. Methods： A stratified cluster random sampling method was used. Height data of grades 1,2,3 pupils within cities and counties of Xiangfan area was collected; a self-compiled questionnaire was used to survey height related factors. Results： Among 2532 children of age 7-9, the average height of boys of each age group is generally higher than that of girls. The heights for both boys and girls are increasing with age. The average growth is 5.35cm for boys and 5.85cm for girls, which is in line with children development mechanism. The heights of the boys and girls are slightly lower than the national average height of the same age, but the difference is not significant （P 〉0.05）. Conclusion： The students＂ height is closely related to heredity and environmental factors. In order to prompt healthy growth, group intervention measures integrating diet, exercise, sleep, psychological intervention and treatments should be taken during their strong-growth primary school ages.
