广西沿海地区2016年学龄前儿童下肢爆发力影响因素

Determinant factors of lower limb explosive force among preschool children in Guangxi coastal areas in 2016

目的掌握广西沿海地区3~6岁学龄前儿童下肢肌肉力量发展的主要影响因素,为有针对性地开展学龄前儿童体质健康指导工作提供参考依据。方法采用分层整群抽样的方法,抽取钦州、北海、防城港共15所幼儿园874名3~6岁学龄前儿童进行体质测试,并对家长或看护人进行当面一对一问卷调查,使用单因素分析和多元线性回归分析等统计学方法对儿童下肢爆发力的影响因素进行分析。结果对影响学龄前儿童下肢爆发力的指标进行相关性分析,发现儿童的性别、年龄、身高、体重以及出生时体重和身长、胎龄、父母亲受教育程度、父母亲年龄、母亲的身高和体重共13个指标相关性有统计学意义(P值均<0.05),将指标纳入多元线性回归分析,发现学龄前儿童年龄、性别、体重、身高、父亲受教育程度、母亲年龄对学龄前儿童下肢爆发力有影响作用(P值均<0.05)。结论生长发育状况和父亲受教育程度等是广西3~6岁学龄前儿童下肢爆发力发展的重要影响因素,出生时优生优育和父母亲身高体重等对学龄前儿童下肢爆发力的预测作用不显著。

Objective To understand the main influencing factors of lower limb muscle strength development in children aged 3-6 in coastal areas of Guangxi, and to provide a reference for physical education and health management physical health work for children. Methods Using stratified cluster sampling method, a total of 15 kindergarten children perform selected from Qinzhou, Beihai and Fangcheng Gang were administered physical tests, and the parents( or guardians) received a face to face questionnaire survey, Univariate analysis and multivariate linear regression analysis were used to analyze determinant factors of lower limbs explosive force. Results The correlation analysis of the factors affecting lower limb explosive force of children aged 3-6 years showed that there were significant differences in the correlation of 13 indicators including gender, age, height, weight, birth weight and body length, gestational age, parents’ education level, parents’ age, and mother’ s height and weight( P<0.05). Furthermore, multiple linear regression analysis showed that age, gender, weight, height, father’ s education level and mother’ s age had significant effects on lower limb explosive force of 3-6 years old infants in Guangxi coastal areas( P < 0. 05). Conclusion Growth and development, as well as paternal educational level plays an important role in the development of lower limb explosive force of children aged 3-6 in coastal areas of Guangxi, while weight and length at birth, parental height and weight shows no association with it.
