NCT ID NCT07435857
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study followed 221 overweight or obese women and their children for 8 to 10 years after a previous trial where some women exercised during pregnancy. Researchers want to see if exercise during pregnancy improves metabolic health, like blood sugar and body weight, in mothers and their kids over the long term. The study is observational and does not test a new treatment.

Who is studied
This follow-up of a randomized trial included 300 overweight/obese pregnant women (prepregnancy BMI ≥24, \<12⁺⁶ weeks gestation) from Peking University First Hospital (Dec 2014-Apr 2017). They were randomized to an exercise group (n=150, cycling three times/week, ≥30 min/session) or control group (n=150, usual activities). After excluding those who missed the OGTT (18 exercise, 17 control), 132 and 133 mother-offspring pairs, respectively, were included.
