Objective The aim of this study was to evaluate the association between breastfeeding duration and dietary intakes during childhood among children exposed and unexposed to gestational diabetes mellitus (GDM) in utero.

Methods A total of 107 children exposed (GDM+) and 54 children unexposed (GDM-) to GDM in utero participated in this cohort study. At the time of the visit, data on breastfeeding duration (in months) were retrospectively collected using a questionnaire. A trained dietician assessed child's dietary intakes using two 24h recalls. Mean dietary intakes of children were used. Spearman correlations were performed to assess the association between total and exclusive breastfeeding duration with children's diet, i.e. intakes of fruits and vegetables, meat and alternatives, grain products, milk and alternatives, energy and dietary fibers intakes as well as % of energy from macronutrients. Dietary intakes of children were compared according to the median duration of breastfeeding (8 months) in GDM+ and GDM- children separately. Dietary intakes were also compared between GDM+ and GDM- children breastfed ≤ 8 months and those breastfed > 8 months. Adjustments for age and sex were made.

Results Mean age of GDM+ and GDM- children were 6.0±2.5 and 7.1±3.0 years, respectively (p=0.01). Mean duration of total and exclusive breastfeeding were similar between GDM+ and GDM- children (p>0.05). Among GDM+ children, neither total nor exclusive breastfeeding duration were correlated with dietary intakes (p>0.05). However, among GDM- children, total breastfeeding duration tended to be negatively associated with energy intake (r=-0.27, p= 0.07) and with grain products servings (r=-0.29, p= 0.06). Dietary intakes were similar between children breastfed ≤8 months and those breastfed >8 months among GDM+ and GDM- children. However, GDM+ children breastfed ≤8 months consumed significantly less dietary fibers when compared to GDM- children that were breastfed during >8 months (p=0.04).

Conclusion These results suggest that breastfeeding duration tend to be associated with diet in GDM- children but is not associated with later dietary intakes among GDM+ children, a group at high risk of obesity and type 2 diabetes.
