Abstract

OBJECTIVE: To evaluate body composition, nutritional status through food selectivity and degree of inadequate intake, and mealtime behavior in children with autism spectrum disorder (ASD) compared to neurotypical children. METHOD: A cross-sectional case-control study was carried out in 144 children (N = 55 with ASD; N = 91 with neurotypical children) between 6 and 18 years of age. Body composition, nutritional intake, food consumption frequency (FFQ), and mealtime behavior were evaluated. RESULTS: Results showed a greater presence of children with a low weight (18.4% ASD vs. 3.20% comparison group) and obesity (16.3% ASD vs. 8.6% comparison group) in the ASD group for body mass index (BMI) categories (p = .003; number needed to take [NNT] = 8.07). The presence of obesity in ASD children compared to the comparison group was even higher when considering the fat component (47.5% ASD vs. 19.4% comparison group, p = .002; NNT = 10.3). ASD children had greater intake inadequacy (50% ASD vs. 22% comparison group, p = .014; NNT = 3.58), high food selectivity by FFQ (60.6% ASD vs. 37.9% comparison group, p < .037; NNT = 4.41), and more eating problems (food rejection, limited variety, disruptive behavior), compared to neurotypical children (p = .001). CONCLUSION: Children with ASD showed an unbalanced body composition toward both underweight and obesity, a greater degree of inadequate intake, high food selectivity as indicated by their consumption frequency, and more disturbed eating behavior than children with neurotypical development. We suggest monitoring nutritional inadequacies and implementing nutritional strategies to expand the variety of foods children with ASD consume.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
