The length of children’s long bones at age three is determined, not by maternal vitamin D or mother or child’s diet, but simply by genetics, a study suggests.
Canadian researchers followed 357 pregnant women from their third trimester and then measured the length of the eight long bones in their 357 offspring at age three, using a dual-energy absorptiometry (DXA) scan.
“To our knowledge, no one has ever reported on bone length derived from DXA scans in children,” the authors write in the journal Bone.
