Low physical activity levels 1 year after pregnancy complications

OBJECTIVES: Women with previous preeclampsia (PE), gestational hypertension (GH), or gestational diabetes mellitus (GDM) have increased cardiovascular disease (CVD) risk. Physical activity (PA) is an important CVD risk modifier. We aimed to assess PA levels, using a validated objective method, and other modifiable CVD risk factors in women with these previous pregnancy complications. STUDY DESIGN: One year postpartum we assessed PA levels for 1 week in women with previous PE (n = 68), GH (n = 26), GDM (n = 23), and normotensive pregnancies (n = 65), using the ActiGraph-wGT3X-BT™ accelerometer. OUTCOME MEASURES: We assessed adherence to American PA guidelines (≥150 min/week of moderate or ≥75 min/week of vigorous intensity PA), and time spent in moderate and vigorous PA. We also assessed steps/day, blood pressure and anthropometric indices. RESULTS: Recommended PA levels were achieved in only 50%, 39%, and 35% following PE, GH, and GDM, respectively, not significantly different from controls (52%). Differences in moderate and vigorous PA levels and steps/day between the groups were non-significant, except from lower vigorous PA in women with previous GDM. Elevated blood pressure (systolic BP ≥ 120 mmHg and/or diastolic BP ≥ 80 mmHg) was more common after PE and GH. Overweight rates were significantly higher in PE, GH, and GDM groups compared to controls. CONCLUSIONS: Less than half of women achieved recommended PA levels 1 year postpartum. This did not differ significantly between women with previous PE, GH, or GDM compared to controls. Measures to increase PA in postpartum women are warranted, especially in women with pregnancy complications associated with high risk of premature CVD.
