Recruitment feasibility and dietary and behavioral patterns in toddlers with ASD: Preliminary results from the Autism Eats program

Abstract

Background

Problematic mealtime behaviors and inadequate diet quality are pressing concerns for children with autism spectrum disorder (ASD). This study aimed to evaluate recruitment feasibility and baseline outcomes of the Autism Eats program for children under 3 years with ASD.

Methods

Recruitment feasibility was assessed through reach and participation rates. The Healthy Eating Index (HEI-2015) scores were calculated from 3-day food records. Problematic mealtime behaviors were assessed with the Brief Autism Mealtime Behavior Inventory. Parental feeding practices were assessed using the Child Feeding Questionnaire. Anthropometric measurements of children and parents were taken. Weight-for-length percentiles were calculated based on the CDC growth charts. Descriptive statistics, one-sample t-tests, and Spearman's rho correlations were used for data analysis.

Results

Of the contacted dyads, 74 % agreed to participate. All 51 enrolled dyads completed baseline survey (100 %), and 98 % completed 3-day food records and anthropometric measurements. Significantly higher problematic mealtime behaviors were observed, compared to the reference (e.g., Total score 55.7 vs. 32.5; p < .001). Children with ASD exhibited lower HEI-2015 scores than national data (e.g., Total score 59 vs. 62). A large proportion of the children (29 %) had a weight-for-length ≥ 95th percentile. Several significant associations were found among mealtime behaviors, diet quality, parental feeding practices, and weight status.

Conclusion

Recruitment was highly feasible, and the findings suggest that early nutrition intervention may hold promise in addressing problematic mealtime behaviors and promoting healthier dietary habits in young children with ASD.
