Maternal Weight Levels Before and During Gestation as Indicators of Pregnancy Outcomes in Zibo, China

Aims: To examine the correlation of maternal weight gain before and during pregnancy with the health of mother and child, and to provide guidelines on weight control during pregnancy among Chinese women. Study Design: Subjects were grouped according to pre-pregnancy body mass index (BMI) and gestational weight gain, and then evaluated based on their risks of pregnancy complications. The birth outcomes were also recorded to study the influence of mothers’ weight gain on the health of their children. Methodology: We included a total of 808 primiparous women who finished all periodic examinations in Zibo Central Hospital, China during the study period. Incidences of multiple common pregnancy complications were recorded to evaluate the health risk of each group. After delivery, the nutritional conditions of newborns were evaluated with their body weights. Results: Observation to subjects reveals the positive correlation between pre-pregnancy BMI and the incidence of gestational outcomes. Particularly, gestational weight increase between 10 and 15 kg is recommended to counteract negative influence of non-optimal pre-pregnancy BMI and lead to satisfactory pregnancy outcomes.
