Overweight pregnancy increases risk of birth defects, study says according to : CNN

Among the babies of mothers in obesity class I, the rate was 3.8%; in obesity class II, 4.2%; and obesity class III, 4.7%. Obese women, overweight women and sedentary women "have a very high incidence of diabetes and high blood pressure in pregnancy. By comparison, the proportion of major birth defects among the children of overweight mothers was 3.5%. She noted that these results show a connection -- but cannot prove a direct cause -- between maternal weight and birth defects. (CNN) Risks of major birth defects increased in step with the severity of a mother's obesity or overweight, a study published Wednesday in the BMJ medical journal found.




The risk of babies being born with major birth defects increases, the more overweight or obese a mother is, according to a Swedish study. The records contained information on pregnancy characteristics, along with any cases of major congenital malformation and a number of organ-specific malformations that were diagnosed during infants' first year of life. The risk for heart defects, nervous system malformations and limb defects also rose progressively as BMI increased from overweight to class III obesity and maternal obesity was associated with an increase in genital and digestive system malformations. Previous studies have already established that maternal obesity is a risk factor for congenital malformations, but Martina Persson (Karolinska Institute, Stocklhom) and colleagues wanted to investigate whether overweight was also a risk factor and whether that risk rose with increasing BMI. The team analyzed medical birth records made between 2001 and 2014 for more than 1.2 million births in Sweden.
