"Some clinicians have been pushing weight restriction for all classes of obese women. Our study indicates that a single standard for optimal weight gain for obese women may not fit the bill. Instead, we need to consider level of obesity and advise women accordingly," said Dr. Lisa M. Bodnar, lead author of the study.
The authors suggested that the following pregnancy weight gain ranges to optimize birth outcomes- 20 to 30 pounds for class 1 women; 5 to 20 pounds for class 2 women and less than 10 pounds for class 3 women.
Women who gain less than the suggested amounts can still have healthy pregnancies provided their dietary intake is being monitored to ensure proper nutrition, said the authors.
"Obese women may face increased complications of pregnancy. Appropriate weight gain may lessen these risks for the baby, so we strongly encourage all obese women to receive nutrition and lifestyle counseling throughout their pregnancies," said Dr. Barbara Abrams, senior author of the study.
The study has been published online in the American Journal of Clinical Nutrition.
