Predictors of Favorable Growth Patterns During the Obesity Epidemic among US School Children
Clinical pediatrics(2015)
摘要
Objective. To report the prevalence of favorable growth patterns, including healthy weight maintenance (HWM) and return to healthy weight (RHW) among US school-age children. Methods. A longitudinal analysis of childhood growth patterns from the Early Childhood Longitudinal Study–Kindergarten Cohort was completed (n = 9416). The primary outcome included describing the prevalence of HWM/RHW patterns using consecutive child growth data from kindergarten to fifth grades. Multivariate logistic regression was used to explore predictors of HWM/RHW. Incidence of RHW is calculated by grade level. Results. Seventy percent (n = 6617) of children enter kindergarten at a healthy weight and approximately 70% maintained a healthy weight through fifth grade. Among overweight/obese kindergartners, only 17.1% outgrew their weight risk (RHW) by fifth grade. Conclusions. Fewer than 1 in 5 at-risk children outgrow their weight risk during school-age yet a majority of healthy weight children can maintain healthy weight during a critical growth period. Future work should explore additional socioecologic factors associated with favorable growth.
