Breastfeeding in women with type 1 diabetes: exploration of predictive factors.

Objective: To identify predictive factors for initiation and maintenance of breastfeeding with a focus on mothers with type 1 diabetes.

Research Design And Methods: This is a prospective observation survey, using a case-control design, comparing the outcomes of 108 mothers with type 1 diabetes with 104 mothers without diabetes that were matched for parity and gestational age. Mother and infant outcomes were collected from medical records and through telephone interviews 2 and 6 months after delivery. Predictive factors were calculated by logistic regression analyses.

Results: Mothers with diabetes were less likely to partly or exclusively breastfeed their children at 2 months (OR 0.42 [95% CI 0.18-0.96], P = 0.041) and 6 months (0.50 [0.27-0.90], P = 0.022) than mothers without diabetes. On multivariable analysis, type 1 diabetes did not remain an independent predictive factor. Instead, higher education level and breastfeeding at discharge from hospital were predictive factors for breastfeeding at 2 months postpartum. These variables as well as delivery >37 weeks and early breastfeeding predicted breastfeeding 6 months postpartum.

Conclusions: Factors associated with maternal diabetes, such as problems with establishing breastfeeding in the early postpartum period, affects the likelihood of long-term breastfeeding.
