Objective: To explore associations of early infant feeding with (i) eating patterns in the second year of life and (ii) weight status in the fourth year of life in a prospective cohort of children in Scotland.
Design: Growing Up in Scotland (GUS) longitudinal birth cohort study (2005-2008).
Setting: Scotland, UK.
Subjects: Children aged 9-12 months (n 5217) followed through to 45-48 months.
Results: Infant feeding was associated with eating patterns, defined by using SPSS two-step cluster analysis, in the second year of life. Children who were ever breast-fed compared with never breast-fed (adjusted OR = 1·48, 95 % CI 1·27, 1·73) were more likely to have a positive eating pattern (Cluster 2). Children who started complementary feeding at 4-5 months or 6-10 months compared with 0-3 months (adjusted OR = 1·32, 95 % CI 1·09, 1·59 or AOR = 1·50, 95 % CI 1·19, 1·89) were more likely to belong to Cluster 2. Breast-feeding was negatively associated with being overweight or obese in the fourth year of life compared with no breast-feeding (adjusted OR = 0·81, 95 % CI 0·81, 1·01). Introduction of complementary feeding at 4-5 months compared with 0-3 months was negatively associated with being overweight or obese (adjusted OR = 0·74, 95 % CI 0·57, 0·97).
Conclusions: Breast-feeding and introduction of complementary feeding after 4 months were associated with a positive eating pattern in the second year of life. Introduction of complementary feeding at 4-5 months compared with 0-3 months was negatively associated with being overweight or obese.
