A new study published in the journal “Pediatric Obesity” showed that low levels of 25-hydroxyvitamin D (25-OH D) the mother during pregnancy is associated with a greater body mass index (BMI) in offspring at ages 4 to 6 years.
Scientists from the University of Crete in Heraklion, Greece, examined data on 532 children aged 4-6 years and 370 mothers. The concentration of 25-OH D in mothers was assessed at 14 weeks of pregnancy. The average concentration was 46.3±15,7 nmol/L. About two thirds of the mothers participating in the study had a vitamin D concentration of<50 nmol/L.
The results of the study showed that children whose mothers had a level of 25-Oh D<a 37.7 nmol/l, had higher BMI and waist circumference at age 4 to 6 years. A decrease in the concentration of 25-Oh D by 10 nmol/l were inversely associated with BMI and waist circumference in the offspring.
