Body mass index is associated with appropriateness of weight gain but not leisure-time physical activity during pregnancy.

Background: Little is known about how leisure-time physical activity (LTPA) influences gestational weight gain (GWG) among body mass index (BMI) categories. The purpose of this study was to examine the relationship between pregnancy LTPA and the proportion of normal, overweight, and obese women who meet GWG recommendations.

Methods: Participants included 449 subcohort women from the Pregnancy Outcomes and Community Health (POUCH) study.
