Footnote 2.You and the pregnant women you care for share common goals: a healthy pregnancy, a safe delivery, and a healthy baby. To achieve these goals, you need to work together with pregnant women.

Obesity—having a body mass index (BMI) of 30 or higher—is one of the most common health issues in U.S. women of reproductive age,1 affecting 36.5% of women ages 20 to 39.2 Evidence shows that obesity is associated with increased risk of health complications during pregnancy and after delivery. Research also notes several potential effects on women, fetuses, and, in the long term, children.1

Working together means empowering pregnant women by framing BMI as just one factor in a healthy pregnancy, and by educating them about using BMI and other risk classifications to develop individual healthy pregnancy plans.

Pregnancy for Every Body aims to help providers and pregnant women work toward these common goals.
