Longitudinal Examination Of Weight-For-Length And Developmental Screening Results In Infancy And Toddlerhood

The current study examined whether high infant weight-for-recumbent-length (WFL) percentile (i.e., >= 85th percentile) at 6 months of age longitudinally related to motor skills, problem solving, and personal/social outcomes on a developmental screener (Ages and Stages Questionnaire-3) at 9 months and 18 months of age. Data were extracted from the medical record at a primary care clinic serving primarily low income and racial minority infants (n = 538). WFL category at 6 months was not related to developmental screener outcomes at 9 or 18 months in both unadjusted analyses and adjusted analyses controlling for relevant covariates.
