- Risk of having a neonate with adiposity >90th centile is almost 66% higher in pregnant women who decrease their exercise levels at 15-20 weeks of gestation vs those who do not change.
- Risk almost doubles on comparing women who decrease vs those who increase their exercise levels.
Why this matters
- Study endorses previous reports which states that women who cut back exercise at late pregnancy have heavier and longer babies.
- The authors, however, call for objectively measured estimates of exercise levels to replicate their findings.
- Chances of giving birth to a neonate with adiposity >90th centile were higher in women who decreased exercise level between 15 and 20 weeks’ gestation vs those who did not (aOR, 1.66; 95% CI, 1.09-2.54).
- Chances were doubled on comparing women who decreased vs those who increased exercise level (aOR, 2.09; 95% CI, 1.20%-3.61%).
- No association was observed for change in exercise levels at 15 weeks’ gestation.
- Secondary analysis of 1200 mother-infant pairs.
- Neonatal adiposity assessed by using air displacement plethysmography.
- Exercise data collected by interviewing women at 15 and 20 weeks.
- Funding: None disclosed.
- Self-reported evaluation of exercise level.
- Data for pre-pregnancy exercise unavailable.
