A longitudinal study of maternal feeding and children's picky eating.

This study aimed to estimate the rate of persistent picky eating (PE) in children 3-8 years of age, and to characterize children with PE and their mothers. From a base sample of 1055 mothers of children 3.4 ± 1.3 years old, we selected those who described their children as picky eaters (PEs; n = 185, 17.5%) for a longitudinal study. 109 PE dyads participated, as well as a matched comparison group of dyads without PE (n = 106). At T1 mothers self-reported on trait anxiety, perfectionism, attachment style; as well as on the child's behavioral problems, their temperament, and their executive function. The participants were re-evaluated twice, at two-year intervals (T2 and T3). At T2 the mothers self-reported on their personality, on their child feeding practices, and reported their child's eating behavior. At T3 the mothers self-reported on their feeding style and the children self-reported on a pictorial frequent food questionnaire. PE persisted throughout T2 and T3 in 22.5% of T1 PE children in the longitudinal study, or in 3.94% of the base sample. The child characteristics that distinguished the PE and non-PE groups at T1 predicted 9-10% of the variance of T3 PE. Maternal feeding practices at T2 contributed 1-2% to the explained variance. It can be concluded that for the overwhelming majority of children, PE is a passing phase. Maternal feeding practices have limited long-term influence on children's PE. Unless PE is persistent and severe, parents would best be advised to relax their feeding efforts.
