(Wiley) A new study has examined whether managing weight during pregnancy might affect children’s bone mass.In the Journal of Bone and Mineral Research study, investigators analyzed prospective data from 2,167 mother-child pairs from Portugal. In under/normal weight mothers, weight gain during pregnancy was associated with slightly increased bone mass at seven years of age in children, while in overweight/obese mothers, no beneficial effect of weight gain on bone mass was observed.
