PA & Risk of Preterm Birth in African American Women

Women’s Health Issues; ePub 2018 May 7; Straughen, et al

There is a decreased prevalence of preterm delivery (PTD) among African American women who participate in a leisure time physical activity (LTPA), but the protective effect varies by maternal body mass index (BMI). This according to a recent study that included 1,410 African American women delivering singleton infants. LTPA and walking was classified for a purpose as 0, 1 to 19, 20 to 39, and ≥40 minutes/day and stair climbing as 0, 1 to 5, 6 to 9, and ≥10 times per day. Among the findings:

  • Overall, 16.4% of deliveries were preterm.
  • LTPA was associated with a decrease prevalence of PTD, but stratification by maternal prepregnancy BMI suggested that LTPA was only protective against PTD among normal weight women.
  • Stair climbing ≥10 times per day was associated with a decreased prevalence of PTD among normal weight and overweight women.
  • Walking for a purpose was not associated with PTD.
