Longitudinal associations of gross motor development, motor milestone achievement and weight-for-length z score in a racially diverse cohort of US infants.

ABSTRACT:

Objectives

To investigate longitudinal associations between gross motor development, motor milestone achievement and weight-for-length z scores in a sample of infants. In a secondary aim, we explored potential bidirectional relationships, as higher weight-for-length z scores may impede motor development, and poor motor development may lead to obesity.

Design

The design was an observational birth cohort.

Setting

We used data from the Nurture study, a birth cohort of predominately black women and their infants residing in the Southeastern USA.

Participants

666 women enrolled their infants in Nurture. We excluded infants with missing data on exposure, outcome or main covariates, leaving a total analytic sample of 425 infants.

Primary outcome

The outcome was
