Pregnant women deficient in vitamin D may give birth to obese children

Vitamin D deficiency in pregnant women could preprogram babies to grow into obese children and adults, according to a new study. Researchers found that 6-year-olds born to mothers with very low vitamin D levels during their first trimester had bigger waists -- about half an inch plumper on average -- than peers whose mothers had enough vitamin D in early pregnancy. These kids also had 2 percent more body fat.
