Wightkin J, et al. Psychosocial predictors of being an underweight infant differ by racial group: a prospective study of Louisiana WIC Program participants. Matern Child Health J. Jan 2007;11(1):49-55.
The researchers identified psychosocial predictors of having low-birthweight infants among mothers enrolled in the Louisiana WIC Program. Among blacks, mothers with an eighth grade education or less had the highest risk of having underweight infants. Among whites, those who initiated prenatal care in the third trimester were most likely to have underweight infants.
