Abstract:

Objective To explore the current situation and influencing factors of gestational weight gain for singleton pregnant women. Methods From June to October 2020，a total of 393 pregnant women who had registered for antenatal checkups at an obstetric clinic of a tertiary obstetrics and gynecology hospital in Shanghai and planned to give birth at the same hospital were selected through convenience sampling. The General Information Questionnaire，Pregnancy Health Literacy Questionnaire and Childbirth Self-Efficacy Questionnaire were used to collect data. Multivariate logistic regression analysis was used to analyze the influencing factors of weight gain during pregnancy. Results A total of 393 women were included in the analysis. Participants’ average gestational weight gain was（13.66±6.10） kg. The proportion of women with inadequate，appropriate and excessive gestational weight gain were 35.6%，32.3% and 32.1%，respectively. Logistic regression analysis showed that the influencing factors for gestational weight gain included education background，previous medical history，pre-pregnancy body mass index，and attending midwife’s clinic（P<0.05）. Conclusion The proportion of abnormal gestational weight gain was relatively high among singleton pregnant women. Those who had a master degree or above，a previous medical history，a normal pre-pregnancy body mass index，and attended midwife’s clinic during pregnancy were at lower risks of abnormal gestational weight gain. Obstetric nurses should pay more attention to gestational weight management，giving full play to midwife’s antenatal clinic，and implementing health education and counseling related to gestational weight management，in order to promote appropriate gestational weight gain and to improve maternal-fetal outcomes.
