Li N, et al. - Using data from mother–child pairs enrolled in the Health Outcomes and Measures of the Environment (HOME) Study (2003–2006), the researchers intended to investigate whether early-life weight status was associated with children's cognition. They used weight-for-length/height standard deviation (SD) scores to evaluate children's early-life weight status. Associations between early-life weight status and cognition were estimated using linear mixed models. It was observed in the findings that early-life weight status was inversely associated with children's perceptual reasoning and working memory scores and possibly with full-scale intelligent quotient scores within this cohort of typically developing children.
