Breastfeeding patterns of mothers with type 1 diabetes: results from an infant feeding trial

• Background Both the initiation and maintenance of breastfeeding have been reported to be negatively affected by maternal type 1 diabetes (T1D). The aim of this study was to prospectively examine the breastfeeding patterns among mothers with and without T1D participating in a large international randomized infant feeding trial (TRIGR). Methods Families with a member affected by T1D and with a newborn infant were invited into the study. Those who had HLA-conferred genetic susceptibility for T1D tested at birth with gestation andgt;35 weeks and were healthy were eligible to continue in the trial. Among the 2160 participating children, 1096 were born to women with T1D and 1064 to unaffected women. Information on infant feeding was acquired from the family by frequent prospective dietary interviews. Results Most (andgt;90%) of the infants of mothers with and without T1D were initially breastfed. Breastfeeding rates declined more steeply among mothers with than without T1D being 50 and 72% at 6 months, respectively. Mothers with T1D were younger, less educated and delivered earlier and more often by caesarean section than other mothers (p andlt; 0.01). After adjusting for all these factors associated with the termination of breastfeeding, there was no difference in the duration of breastfeeding among mothers with and without T1D. Conclusions Maternal diabetes status per se was not associated with shorter breastfeeding. The lower duration of breastfeeding in mothers with T1D is largely explained by their more frequent caesarean sections, earlier delivery and lower age and education.
