Abstract:Objective To explore the status of breastfeeding at 0-6 months postpartum and its related influencing factors in Suzhou, and to analyze the interaction of gestational diabetes mellitus and gestational weight gain of pregnant women onbreastfeeding. Methods We selected 4,256 pregnant women who were hospitalized and delivered in a hospital in Suzhou from June 2016 to March 2020 and met the inclusion criteria to serve as the research subjects. Data about general information of the pregnant women, pre-pregnancy weight, pre-delivery weight, delivery status, and incidence of gestational diabetes mellitus during pregnancy were collected, and their weight change during pregnancy was calculated. The status of breastfeeding at 0-6 months postpartum was investigated by telephone follow-up combined with postpartum visits. Results The average age of the pregnant women included in the study was (29.52±8.74) years. 15.20% of the pregnant women suffered from gestational diabetes mellitus. 14.80% of the pregnant women had insufficient weight gain during pregnancy, while 42.55% had excessive weight gain. 57.38% of the research subjects adopted breastfeeding within 6 months after delivery. The results of multivariate logistic regression analysis showed that women aged above 25 years(OR=1.68-3.82), with high school education or above(OR=1.83-2.23), and with full-term delivery (OR=1.84) were more likely to breastfeed, but the breastfeeding rate was lower in those with overweight (OR=0.82) and obesity (OR=0.82) before pregnancy, willingness to give birth again (OR=0.67), gestational diabetes mellitus (OR=0.61) and excessive(OR=0.61) or lower (OR=0.63) weight gain during pregnancy. Interaction analysis displayed that the breastfeeding level was significantly lower in women with gestational diabetes mellitus and lower or excessive weight gain during pregnancy than in those without gestational diabetes mellitus and with normal weight gain during pregnancy, and the interaction index was 1.67 (1.01, 4.97) (P=0.02). Conclusions Complications like gestational diabetes mellitus and lower or excessive weight gain during pregnancy are important factors affecting breastfeeding, and there is an additive interaction between these two complications.
