An exploratory study of predictors of cognition in two low-income samples of infants across the first year of life.

ABSTRACT:

Objective

In this exploratory longitudinal study we assessed cognitive development in a community sample of infants born into predominantly low-income families from two different urban sites, to identify family and community factors that may associate with outcomes by 1 year of age.

Method

Infant-mother dyads (n = 109) were recruited in Boston and Los Angeles community pediatric practices. Infant cognition was measured using the Mullen Scales of Early Learning when the infant was aged 2, 6, 9, and 12 months. Longitudinal linear mixed effects modeling and linear regression models explored potential predictors of cognitive outcomes.

Results

Cognitive scores were lower than the reference population mean at both 6 and 12 months. There were site differences in demographics
