Correlation between gestational diabetes mellitus and delayed onset of lactogenesis / 中华护理杂志

ABSTRACT

Objective To explore the correlation between gestational diabetes mellitus(GDM) and delayed onset of lactogenesis(DOL),providing references for prevention of DOL among gravidas with GDM.Methods From March to September 2016,gravidas in three tertiary hospitals in Nanjing for antenatal examination were screened for glucose tolerance,and 275 gravidas diagnosed with GDM were assigned into the GDM group,275 gravidas with normal glucose tolerance were assigned into the non-GDM group.Timing of maternal perception of onset of lactogenesis (OL) was recorded and breast milk postpartum 48h to 72h was collected for detecting lactose concentration.Chisquare test was used to compare rate of DOL in two groups,t-test was used to compare difference of lactose concentration between two groups,Pearson correlation was used to analyze the relationship of lactose concentration in breast milk and timing of OL,and multiple logistic regression model was used to analyze impact of GDM on DOL.Results Rate of DOL in the GDM group was higher than that in the non-GDM group,and the difference was statistically significant(P＜0.05).Lactose concentration in the GDM group was lower than that in the non-GDM group,and the difference was statistically significant(P＜0.05).There was a negative linear correlation between lactose concentration and timing of OL 48-72h after delivery.Primipara and GDM were risk factors of DOL.Conclusion Timing of OL among GDM puerperae is later than non-GDM puerperae,and GDM puerperae are at higher risk of DOL.More attention should be paid and measures should be taken for its prevention.
