Determinant factors of lower limb explosive force among preschool children in Guangxi coastal areas in 2016 / 中国学校卫生

ABSTRACT

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.
