Trajectories of picky eating during childhood: A general population study

Objective This cohort study describes the prevalence of picky eating and examines prognostic factors for picky eating trajectories during childhood. Methods 4,018 participants of a population-based cohort with measurements from pregnancy onwards were included. Picky eating was assessed by maternal report when children were 1.5, 3, and 6 years old. The associations of child and family characteristics with trajectories of picky eating were examined using logistic regression. Never picky eaters were used as the reference group. Results Prevalence of picky eating was 26.5% at 1.5 years of age, 27.6% at the age of 3 and declined to 13.2% at 6 years. Four main picky eating trajectories were defined: (1) never picky eating at all three assessments (55% of children), (2) remitting (0-4 years, 32%), (3) late-onset (6 years only, 4%), and (4) persistent (all ages, 4%). This implies that almost two thirds of the early picky eaters remitted within 3 years. Male sex, lower birth weight, non-Western maternal ethnicity, and low parental income predicted persistent picky eating. More often late-onset picky eaters were children of parents with low income and non-Western ethnicity. Discussion We found that nearly half (46%) of children were picky eaters at some point during early childhood. Remittance was very high. This suggests that picky eating is usually a transient behavior and part of normal development in preschool children. However, a substantial group of persistent picky eaters, often from a socially disadvantaged background, continues to have problems beyond the preschool age.
