Excess pregnancy is risk-free for delivery complications, says study



Women with more weight than recommended while pregnant can increase their chances for serious delivery complications, a study of over half a million births in New York City suggests.

Women who get more than 20 pounds above the guideline values ​​have higher rates of heart failure, severe high blood pressure and require blood transfusion or ventilation, the researchers report on Obstetrics & Gynecology.

"We have seen a great surge in … maternal mortality in this country, and when we look at factors of potential danger to be changed, gestational weight gain may change throughout pregnancy, "says leading author Dr. Marissa Platner of Emory Healthcare and the Emory School of Medicine in Atlanta, In 2009, the National Academy of Medicine changed the rules for weight during pregnancy based on female pre-pregnancy body mass index (BMI, weight ratio up to height).

Women in the normal BMI range 18.5-24.9 are encouraged to get 25 to 35 pounds during pregnancy. Those with BMI below 18.5 should get 28 to 40 pounds. Women who are overweight before getting pregnant should get lower during pregnancy: 15 to 25 pounds for those with BMI between 25 and 29.9 and 11 to 20 pounds for those with BMI of 30 or higher.

Nearly half of all pregnant women in the US get more than what is recommended, however, especially those overweight or obese before pregnancy, the authors have stated.

"It's important to optimize your nutrition, diet and exercise before you become pregnant and then in pregnancy," Platner says in telephone interviews. "This is one of the most important things you can do to affect your pregnancy results."

For the new study, researchers reviewed 515,148 identical matches using 2008-2012 of New York City data including weight information pre-pregnancy and gestational weight gain, as well as serious transmission-related complications such as life-threatening diagnostics, life-saving or death-saving procedures.

a third earned within the recommended range, another third earned 1-19 pounds more than recommended and 8 percent earned more than 20 pounds above the guideline for their pre-pregnancy BMI.

In general, two groups with weights are above the guideline The range has higher transmission complication rates. For example, these women are almost four times more likely to experience heart failure during a procedure, and those two and a half times more likely to require ventilation.

"We have seen an increase affecting women across the spectrum for all pre-pregnancy weights," says Platner. "Many physicians and women focus on weight gain in overweight or obese groups, but it's important for everyone to talk about it, not shiny over it because they are thinner before pregnancy."

Women whose pre-pregnancy BMI is below normal is the highest weight loss gain over the guideline range. But apart from gestational weight gain, severe complication rates are highest for women with pre-pregnancy BMI in obese areas.

Women and their doctors need to know about these guidelines for weight gain during pregnancy, Dr. Michelle Kominiarek, a maternal-fetal specialist with Northwestern Medicine in Chicago, who is not involved in the study.

"A weight-loss discussion and approach to achieving those goals should be a priority for providers to their patients," he said via email.

Platner and his team are researching the best ways to talk to women about eating and exercising during pregnancy. For example, that a healthy calorie intake increase is about 250 per day, she said.

"A healthy diet benefits both the mother and the baby," Dr. Sarka Lisonkova of the University of British Columbia in Vancouver, who was not involved in the study.

"Pregnancy is a great motivating factor to start or continue a healthy lifestyle, including a balanced diet with many fruits and vegetables," Lisonkova said via email. "This way of life should continue beyond pregnancy."
