Methods A total of 512 parturients and 512 infants who were delivered in the obstetrics department of Taikang Xianlin Gulou Hospital, Nanjing University School of Medicine from January 2014 to December 2016 were selected. The data of mothers' pre-pregnancy body mass index (BMI) and weight gain during pregnancy were collected for statistical analysis. Children were followed up from December 2019 to March 2020. Their height and weight were measured, and eating behaviors were evaluated. The effects of pre-pregnancy weight, weight gain during pregnancy, and childhood dietary behaviors on children's weight were analyzed. Results Totally 12.70% of the 512 children aged 3 to 6 years old were detected with overweight/obese. Compared with normal weight children, children whose mothers were overweight/obese before pregnancy (10.51% vs.38.46%,χ*=37.512, P=0.001) and overweight during pregnancy were more likely to be overweight/obese(7.83% vs. 43.78%, χ2=75.201, P=0.001). Also, poor eating habits, picky eating and satiety response scores were higher in overweight/obese children (P=0.001). Logistic regression analysis also showed that pre-pregnancy weight(OR=1.109,95%CI:1.025—1.213), weight gain during pregnancy(OR=1.098, 95%CI:1.031—1.261) and dietary behavior in childhood including poor eating habits(OR=1.113, 95%CI:1.054—1.257), picky eating(OR=1.257, 95%CI:1.232—1.467), and satiety response(OR=1.284, 95%CI:1.135—1.513) significantly affected children's weight. Conclusions Children's weight could be affected by pre-pregnancy weight, weight gain during pregnancy and dietary behavior in childhood. Reasonable control of BMI before pregnancy and weight gain during pregnancy, and active guidance for children to establish healthy dietary behavior will help to reduce the incidence of overweight/obesity in children. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/10.11852/zgetbjzz2020-2052
