New study finds that there is no benefit for children's bone mass if women gain weight during pregnancy. The findings of the study are published in the Journal of Bone and Mineral Research.
A new study has examined whether managing weight during pregnancy might affect children's bone mass.
‘Weight management strategies during pregnancy decreases the cardiometabolic risk of a child such as diabetes, heart disease. Maternal weight has an overall positive association with a child's bone mass hence, pregnancy weight management could negatively affect child bone health.
In the 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 a 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.
Given the well-known adverse implications of excessive weight gain during pregnancy for both the mother and child on various aspects of health, following the current recommendations on pregnancy weight gain should not have consequences on children's skeletal health.
"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. 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 before pregnancy," said lead author Dr. Teresa Monjardino, of the Universidade do Porto, in Portugal.
