NICHD Research Weighs in on Weight Gain during Pregnancy

A assortment of factors can make it unmanageable for women to maintain a goodly burden during pregnancy. But recent NICHD supported research affirms the importance of not gaining excessively much slant during pregnancy to reduce the risk for complications .
New findings from an NICHD-supported study of more than 8,000 women nationally found that first-time mothers who gained more weight than recommended were at increased risk for high lineage imperativeness during pregnancy, cesarean delivery, and delivering a larger-than-gestational-age ( LGA ) baby .
These findings reaffirm the recommendations of the Institute of Medicine ( IOM ) regarding weight gain during pregnancy. Those recommendations, released in 2009, were based on inquiry from the NICHD, other NIH Institutes, and the March of Dimes .
The IOM guidelines recommend the pursue :

  • Pregnant women who are underweight (body mass index [BMI] of less than 18.5) should gain 28 to 40 pounds
  • Pregnant women who are normal weight (BMI of 18.5 to 24.9) should gain between 25 and 35 pounds.
  • Pregnant women who are overweight (BMI of 25 to 29.9) should gain between 15 and 25 pounds.
  • Pregnant women who are obese (BMI greater than 30) should limit weight gain to between 11 to 20 pounds.

Research—including these holocene findings—indicates that staying within the recommend levels can help lower the health risks for mothers and can lead to healthier outcomes for babies.

Evaluating the Data

The newly released findings came from researchers in the Maternal-Fetal Medicine Units ( MFMU ) Network, which is supported through the NICHD ‘s Pregnancy and Perinatology Branch ( PPB ). Using data that had been collected previously for a Network preeclampsia prevention study, MFMU researchers evaluated pregnancy outcomes for more than 8,000 pregnancies, including first-time mothers. For this secondary analysis, the researchers looked at outcomes based on total weight unit advance above and below the 2009 IOM guidelines on weight gain during pregnancy .
Of the 8,293 fraught women who participated in the discipline at multiple sites across the state :

  • 9.5% had weight gain below the recommended guidelines.
  • 17.5% remained within the weight gain guidelines.
  • 73% of women gained more weight than recommended.

Among women who gained more than the recommend sum, the researchers found an increased hazard of gestational high rake pressure in all of the BMI categories ; that is, even if a charwoman was scraggy ahead pregnancy, she was still at increased gamble for high blood pressure during pregnancy if she gained more than the recommend weight. high rake coerce during pregnancy can lead to preeclampsia, a dangerous circumstance that can cause serious short- and long-run health problems for the mother and her fetus .
The cogitation besides found that women who were normal pre-pregnancy weight and those who were overweight were besides at increased gamble for cesarean pitch and for having an LGA baby. previous research showed that LGA babies are at higher risk for give birth wound and may have humble blood boodle and other problems related to glucose regulation at birth .
Cathy Spong, M.D., the Associate Director of the NICHD Extramural Research Program and one of the authors of the analyze said that separate of the problem may stem from the mistake belief that a woman is “ eating for two ” during pregnancy. In fact, pregnant women should eat alone around 300 extra calories per day during pregnancy .

Other NICHD Research on Pregnancy and Weight

Understanding the effects of weight amplification before and during pregnancy is an important part of the NICHD ‘s inquiry portfolio. For exemplify :

  • NICHD research has linked maternal obesity to birth defects such as neural tube defects, conditions in which the spinal cord, brain, and related structures do not form properly.
  • Other NICHD researchers also found that pre-pregnancy obesity increases the risk for an infant to be born with a heart defect by around 15%. Read more about these research findings at Risk of Newborn Heart Defects Increases with Maternal Obesity.
  • NICHD research also found that women who are overweight or obese spend more time in labor than do women who are normal weight.

These are merely a few of the Institute ‘s ongoing projects related to weight gain, corpulence, and fleshiness ahead and during pregnancy .
The cognition gained from this and other research adds to the spectrum on evidence-based information on promoting healthy pregnancies. By understanding more about potential pregnancy complications, including those related to weight, researchers can help minimize risks and improve outcomes for mothers and their babies .
