Health Indicator Report of Obesity in Pregnancy

Women who are not at a healthy weight prior to pregnancy are at increased risk of adverse maternal and infant outcomes. Women who are obese prior to pregnancy have longer hospital stays and higher utilization of medical care during pregnancy.

Healthy People Objective MICH-16.5:

Had a healthy weight prior to pregnancy
U.S. Target: 53.4 percent

How Are We Doing?

The percentage of Utah women with a healthy BMI prior to pregnancy in 2013 was 53.5%, meeting the new Healthy People objective. However, the percentage of women with a normal prepregnancy BMI has decreased over the last decade. The decrease in normal BMI is paired with an increase in the percentage of women with an obese prepregnancy BMI. The proportion of women with an obese prepregnancy BMI increased to 18.5% in 2013.

How Do We Compare With the U.S.?

Currently, there are no nationally comparative data on prepregnancy BMI as the National Center for Health Statistics does not report on this measure. With the new Healthy People objective, data are available via the Pregnancy Risk Assessment Monitoring System (PRAMS). In 2011 (latest data available), Utah had the fourth lowest rate of prepregnancy obesity (16.7%) among the 27 PRAMS states reporting. The range ran from a low of 13.9% in Hawaii to a high of 25.6% in Oklahoma.

What Is Being Done?

In an effort to reduce the rate of obesity in reproductive aged women, emphasis is being placed on maternal preconception health to help women achieve optimal weight and health prior to pregnancy. Women should be counseled on their weight by their primary caregivers as part of well woman care and should be informed of their increased risks for adverse outcomes once becoming pregnant if they are at an unhealthy weight. Women who are pregnant should be counseled about appropriate weight gain during pregnancy and postpartum weight loss to prevent obesity in future pregnancies. The Utah Department of Health's "Utah Nutrition and Physical Activity Plan" offers a comprehensive, statewide obesity prevention agenda, building on initiatives and efforts already underway in many settings in Utah. The focus is on policy and environmental changes that support Utahns making healthier choices every day to improve physical activity and eating patterns.
