First trimester predictors of diet and birth outcomes in low-income pregnant women

Fowles ER, Gabrielson M. First trimester predictors of diet and birth outcomes in low-income pregnant women. J Community Health Nurs. Summer 2005;22(2):117-130.

This study tested a model describing the relationships between various biopsychosocial, behavioral, and cognitive factors on nutritional adequacy and infant birthweight in low-income pregnant women. The findings showed that maternal age, body mass index prior to pregnancy, nutritional knowledge, and infant gestation at birth explained 52% of the variance in infant birthweight. Providing nutritional education throughout pregnancy might lead to improved dietary patterns, which, in turn, might reduce the incidence of low birthweight.
