OBJECTIVE: To explore the relationship between pre-pregnancy BMI, antepartum weight gain and postpartum weight retention. METHODS: 793 postpartum women from certain district of Hefei city were recruited as the observational cohort at 3rd month after delivery. We obtained antepartum information from pregnancy care management system and conducted questionnaire and measurement at 3, 6, 9 and 12 months postpartum. The observation items included baseline data, antepartum weight, weight gain during pregnancy, weight of different timing during one year after delivery. RESULTS: The proportion of pregnant women whose BMI back to normal during 3, 6, 9 and 12 months were respectively 61.92%, 68.73%, 78.18% and 84.24%. Pre-pregnancy BMI of women's weight gain and weight retention during 3, 6, 9 and 12 months differs. After comparing the differences between higher pre-pregnancy BMI group, medium pre-pregnancy BMI group and lower pre-pregnancy BMI group, the differences were statistically significant. There were independent effects between weight gain during pregnancy, time and postpartum weight recovery, but no interactions were shown between them. CONCLUSION: Pre-pregnancy BMI and weight gain during pregnancy were important factors for postpartum weight retention. Using pre-pregnancy BMI as guidance to build reasonable weight gain during pregnancy might reduce the occurrence of postpartum weight retention and promote postpartum recovery.
