Pregnant women who exercise reduce the chances of their child becoming obese later in life according to a New Zealand study.
Doctors say that regular, moderate aerobic exercise has an impact on nutrient stimulation of fetal development leading to a reduction in birth weight, which may have long-term health benefits.
"The modest reduction in birth weight in this study may lead to a long-term reduction in the risk for obesity in offspring of women who exercised in pregnancy," Dr. Paul L. Hofman of the University of Auckland and his colleagues wrote.
The new study found that babies born to mothers who regularly exercised averaged 143 grams lighter than those who did not and also had a lower body mass index.
The lighter infants were not shorter in length and there was no evidence they lacked nutrition.
