Association of maternal birth weight with the risk of low birth weight and small-for-gestational-age in offspring: A prospective single-center cohort study.

BackgroundAlthough low birth weight in Japan has slightly increased over the past several decades, the association between maternal birth weight and pregnancy outcomes remains poorly understood.MethodsIn this hospital-based, prospective cohort study conducted at the National Center for Child Health and Development, we obtained information on pregnant women's birth weight via their maternal and child health handbook. We analyzed 944 women born at term after dividing them into five categories according to their birth weight: ResultsCompared with women with a birth weight of 3000-3499 g, those born with a birth weight ConclusionsOur findings suggest that lower maternal birth weight is associated with small-for-gestational-age and low birth weight in offspring of women born at term
