Approximately 50% of pregnant women from developed countries are either overweight (body mass index [BMI] 25.0-29.9 [calculated as weight in kilograms divided by height in meters squared]) or obese (BMI≥30.0).1 This percentage needs to be considered in the context of the growing epidemic of obesity in the United States. From 1999-2000 to 2013-2014, the Centers for Disease Control and Prevention reported an increase in obesity in adults from 30.5% to 37.7%. In 2011-2014, among US adults aged 20 to 29 years, the prevalence was higher for women (34.4%) compared with men (30.3%).2
