A study published in JAMA evaluated the associations between sedentary behavior (SED), light-intensity physical activity (LPA), and daily step counts with pregnancy outcomes in 470 women enrolled before 13 weeks of gestation. Key findings Higher SED patterns ( sitting ≥10 hours/day) were associated with more than double the risk of adverse pregnancy outcomes, including hypertensive disorders of pregnancy, gestational diabetes, preterm birth, and small-for-gestational-age infants. A very high LPA pattern (7 hours/day) was associated with nearly half the risk of adverse pregnancy outcomes compared with low LPA (3 hours/day; absolute risk [AR], 21.1% vs 40.3%).
Women with moderate (AR, 36.2%) and high (AR, 32.2%) daily step counts had fewer adverse pregnancy outcomes than those with low step counts (AR, 47.7%). Takeaway message Greater light-intensity physical activity and higher daily…
