"We've seen a huge surge. . . maternal mortality in this country and, when we look at the risk factors that can be changed, gestational weight gain may change during pregnancy, ”said head author dr. Marissa Platner of Emory Healthcare and Emory Medical School in Atlanta, Georgia
2009 The National Academy of Medicine has revised guidelines for weight gain during pregnancy for women under the body mass index (BMI, weight, and height ratio).
Women in the range of normal BMI 18.5-24.9 are encouraged to receive 25-35 pounds during pregnancy. Those with a BMI of less than 18.5 should gain 28-40 pounds. Women who are overweight before pregnancy should have a lower pregnancy rate: 15 to 25 pounds for those with a BMI of 25 to 29.9, and only 11 to 20 pounds for those with a BMI of 30 or more.
Almost half of all pregnant women in the United States get more than recommended, especially for those who are overweight or obese before pregnancy. Platner said in a telephone conversation. "This is one of the most important things you can do to influence the outcome of pregnancy." data that included weight pre-pregnancy information and weight gain, as well as severe birth problems such as life-threatening diagnoses, rescue procedures, or death.
Approximately a quarter of women received less than recommended, one-third received the recommended range, one-third ranged from 1 to 19 pounds more than recommended, and one-third received. – more than 20 pounds above the recommendation for their pregnancy BMI.
In general, the two groups whose weight increased above the guideline range were higher in the number of complications. For example, these women were almost four times more likely to have heart failure during the procedure, and about two and a half times more likely to need ventilation.
"We have seen that the increased effect on women across the spectrum occurs before weight loss," Platner said. "Many doctors and women focus on weight gain only in overweight or obese groups, but it is important that everyone talks about it rather than shine as they are thin before pregnancy."
Women with a BMI below normal are was the highest risk of weight gain over the recommended range. However, with the exception of gestational weight gain, the incidence of severe complications was highest in women who had had BMI before pregnancy.
