Association between birth weight and neurodevelopment at age 1-6 months: results from the Wuhan Healthy Baby Cohort.

ABSTRACT:

Objective

The association between birth weight and infants' neurodevelopment is not well understood. We aimed to examine the impact of birth weight on neurodevelopment of infants at age 1-6 months using data from the Wuhan Healthy Baby Cohort (WHBC) study.

Setting and participants

This is a prospective cohort study of 4026 infants from the WHBC study who were born at the Women and Children's Hospital of Wuhan, China between October 2012 and September 2013 and who had complete healthcare records within 6 months after birth. Participants were categorised into three groups according to their birth weight: low birth weight (LBW; birth weight <2500 g), normal birth weight (2500 g ≤ birth weight <4000 g) and macrosomia (birth weight ≥4000 g).
