This chapter examines the influence of maternal weight gained during pregnancy on the birth weight of a newborn infant while controlling for a variety of possibly important confounding factors. The birth weight analysis focuses on the three trimester weight gain measures. The three estimated regression coefficients reflecting the role of maternal weight gain indicate that substantial (nonrandom) influences are likely associated with the second trimester gain and, to a lesser extent, with the first trimester gain. No evidence of an influence from the third trimester gain is present. The polynomial representations of the three weight gain patterns show no convincing evidence of a nonlinear relationship between a mother's weight gained during pregnancy and the log-birth weight of her newborn infant.
