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.
Keywords: favorable growth; growth patterns; health disparities; healthy weight; obesity resilience; school-age.
