Pregnancy Weight Affects Child

0

pregnancy and weightWomen who enter pregnancy overweight or who gain too much weight during pregnancy place their unborn child at risk for obesity later in life, according to a study from Columbia University Medical Center in New York.  Of the 727 Black mothers in this study, 45% were overweight or obese and 64% gained more than the recommended amount of weight during pregnancy. The study found that 22% of the children born to these overweight women were obese and 24% of their body mass was fat by the time they turned 7-years-old. Children born to women who were overweight or obese before pregnancy had a 300% increased risk of obesity.  “Some weight gain during pregnancy is normal, but …gaining too much can put the child at risk for being obese…and…places them at higher risk for future chronic disease,” state the researchers.
