ABSTRACT
This study aimed to investigate if the duration of breastfeeding and the method at initiation of complementary feeding affect eating behaviour in children aged 3-6 years. This is a cross-sectional analysis from the Childhood Obesity Risk Assessment Longitudinal Study project, an ongoing longitudinal cohort study that aims to identify childhood obesity risk factors in Spanish children. A total of 1215 children aged 3-6 years were included. Breastfeeding duration and the method of initiation of complementary feeding [baby-led weaning (BLW), traditional/spoon or mixed method] were evaluated. Eating behaviour at 3-6 years was assessed with the Child Eating Behaviour Questionnaire. Generalized linear models were fitted to assess the association between the aforementioned exposures and eating behaviour. Children breastfed for ≥4 months were less likely to be fussy eaters at 3-6 years compared to those breastfed for <1 month (OR: 0.86 95% CI: 0.76-0.98; p = 0.031). Compared to those children using the traditional/spoon-feeding method, those initiating complementary feeding through BLW or through a mixed approach were more likely to have higher scores on the enjoyment of food (EF) (OR, 95% CI: 1.33, 1.13-1.57; p = 0.001 and 1.17, 1.05-1.30; p = 0.002, respectively) and lower scores on food fussiness (FF) at 3-6 years (0.76, 0.62-0.91; p = 0.004 and 0.87, 0.78-0.98; p = 0.033, respectively). Breastfeeding for ≥4 months and initiation of complementary feeding with the BLW and a mixed approach were associated with greater EF and lower FF, which should endure practice.
