This study examined the relation between gestational weight gain and risk of delivering a small-for gestational-age or large-for-gestational-age infant by race, along with the implications of gaining weight according to the Institute of Medicine guidelines.
Logistic regression methods were used to identify risk factors for small-and large-for-gestational-age births among 2617 Black and 1253 White women delivering at the Johns Hopkins Hospital between 1987 and 1989.
Rate of total weight gain was related to risk of small-and large-for-gestational-age births ; the relationship differed according to maternal body mass index but not race.
No differences in outcome by race were evident for women with low body mass indexes ; among those with average or high indexes, however, Black women were at higher risk of small-for-gestational-age births and at lower risk of large-for-gestational-age births.
Having Black women gain at the upper end of the recomended range is unlikely to produce measurable reductions in small-for-gestational-age births.
Some beneficial reductions in the risk of large-for-gestational-age births may occur if weight gain recommendations are lowered for average-weight and overweight White women.
