Changes in physical activity and TV viewing from pre-pregnan
Adolescent pregnancy contributes to accelerated trajectories of adiposity and cardiometabolic diseases. Two potentially low-cost prevention strategies include promoting physical activity (PA) and limiting television (TV) viewing.

This study sought to characterize PA and TV viewing in a socioeconomically disadvantaged perinatal adolescent population. The study was published in the Journal of Pediatric & Adolescent Gynecology.

A cross-sectional, retrospective 10-item survey was used to explore behavior patterns in 79 predominantly Black (86%) postpartum adolescents.

- Many adolescents reported being active ≥3 days/week in pre-pregnancy; however, many reported low PA in their first, second, and third trimesters.

- Adolescents who reported being active on ≥5 days/week in pre-pregnancy experienced first trimester PA decline, which subsequently plateaued. This group remained the most active throughout pregnancy.

- In postpartum, over half of all adolescents reported low PA and irrespective of PA, spent considerable time watching TV.

Interventions promoting PA coupled with reducing TV viewing during pregnancy and in postpartum may benefit perinatal adolescents. The findings from this study suggest PA history is a predictor of gestational PA, and low PA and high TV viewing in postpartum underscore the need for behavioral intervention.
