Sedentary Behavior and Light-Intensity Physical Activity During Pregnancy and Cardiovascular Health: A Science Advisory From the American Heart Association

Observational evidence is mixed; preliminary evidence links high sedentary behavior with increased risk of hypertensive disorders of pregnancy, shorter gestational age at delivery, low or high birth weight, and elevated maternal BP, lipids, glucose and gestational weight gain

Findings for light-intensity physical activity are limited by fewer studies and less compelling

Future observational studies with rigorous longitudinal designs and larger, diverse samples are needed to characterize associations and inform adequately powered RCTs of decreasing sedentary behavior and increasing light-intensity physical activity
