There is no benefit for children's bone mass if women gain weight during pregnancy, says a new study.
The study, published in the Journal of Bone and Mineral Research, showed that in under and normal weight mothers, weight gain during pregnancy was associated with slightly increased bone mass at 7 years of age in children.
On the other hand, in the case of overweight or obese mothers, no beneficial effect of weight gain on bone mass was observed.
"Until recently, it was a widely held scientific belief that any weight gain from the mother during pregnancy would have a beneficial effect on children's bone mass," said Monjardino.
"Our study results corroborate that there is no benefit in gaining weight above the US Institute of Medicine recommendations for pregnancy weight gain for children's bone mass, in both normal and overweight women prior to pregnancy," added Monjardino.
The team analysed prospective data from 2,167 mother-child pairs.
