BackgroundThis study examined bidirectional relationships between maternal feeding practices and child food responsiveness and satiety responsiveness from 2 to 5 years.MethodsMothers (N = 207) reported their own feeding practices and child eating behaviours using validated questionnaires at child ages 2, 3.7, and 5 years. Cross-lagged analyses were conducted to test for bidirectional effects, adjusting for child BMI z-score (based on measured weight and height) at 14 months.ResultsEating behaviours and feeding practices showed strong continuity across the three time points. Maternal feeding practices (higher reward for behaviour [β = 0.12, p = 0.025] and lower covert restriction [β = −0.14, p = 0.008]) were prospectively associated with higher food responsiveness. Conversely, increased child satiety responsiveness was primarily prospectively associated with mothers’ feeding practices (increased structured meal timing [β = 0.11, p = 0.038], overt [β = 0.14, p = 0.010] and covert restriction [β = 0.11, p = 0.022]). The only exception was family meal setting, which was prospectively negatively associated with satiety responsiveness (β = −0.11, p = 0.035).ConclusionWhile maternal feeding practices and child satiety and food responsiveness show strong continuity between child age 2 and 5 years, maternal feeding practices appear to be associated with child food responsiveness over time. Conversely, child satiety responsiveness, but not food responsiveness, may also be associated with maternal feeding practices over time. These results are consistent with interventions that provide feeding advice to parents on how to respond appropriately to individual child eating behaviour phenotype.Trial registrationACTRN12608000056392.

IMPORTANCE Although multiple cross-sectional and longitudinal studies have established that sleep problems and behavioral difficulties are associated in children, the directionality of this association and whether sleep problems are differentially associated with different types of childhood behavioral difficulties are unclear. Understanding these associations will inform the focus and timing of interventions. OBJECTIVE To determine whether longitudinal and reciprocal associations exist between child sleep problems and externalizing, internalizing, or both behavioral difficulties.

This article documents the longitudinal and reciprocal relations among behavioral sleep problems and emotional and attentional self-regulation in a population sample of 4,109 children participating in Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC)-Infant Cohort. Maternal reports of children's sleep problems and self-regulation were collected at five time-points from infancy to 8-9 years of age. Longitudinal structural equation modeling supported a developmental cascade model in which sleep problems have a persistent negative effect on emotional regulation, which in turn contributes to ongoing sleep problems and poorer attentional regulation in children over time. Findings suggest that sleep behaviors are a key target for interventions that aim to improve children's self-regulatory capacities.
