Association between gestational weight gain and risk of overweight at 3 years old: The Japan Environment and Children's Study
Authors' conclusion
GWG was positively associated with a high risk of overweight at 3 years of age. The risk of offspring overweight was 20%-27% higher and 16%-17% lower with excessive GWG and inadequate GWG, respectively, compared to adequate GWG, based on the aforementioned criteria.
