Heightened sensitivity to sensory information has been associated with food fussiness in both atypical and typical development. Despite food fussiness and sensory dysfunction being reported as common concerns for children with neurodevelopmental disorders, the relationship that exists between them, and whether they differ between disorders, has yet to be established. The current study aimed to examine sensory sensitivity as a predictor of food fussiness in three different neurodevelopmental disorders, whilst controlling for comorbidity amongst these disorders. Ninety-eight caregivers of children with Attention Deficit Hyperactivity Disorder (ADHD; n=17), Tourette Syndrome (TS; n=27), Autism Spectrum Disorder (ASD; n=27), and typical development (TD; n=27) were compared using parental reports of child food fussiness, food preferences and sensory sensitivity. Children with neurodevelopmental disorders were reported to have significantly higher levels of both food fussiness and sensory sensitivity, with children with ASD and TS also showing significantly less preference for fruit than children with TD. Importantly, higher levels of taste/smell sensitivity predicted food fussiness for all four groups of children. In addition, taste/smell sensitivity fully mediated the differences in food fussiness between each group of neurodevelopmental disorder compared to the TD group. The findings highlight that food fussiness is similar across these neurodevelopmental disorders despite accounting for comorbidity, and that greater sensitivity to taste/smell may explain why children with neurodevelopmental disorders are more likely to be fussy eaters.
Research examining the relationship between breastfeeding and infant weight has generated conflicting results. Few studies account for significant covariates and many suffer methodological problems such as retrospective self-report. The current study aimed to investigate relationships between breastfeeding duration, infant weight and eating and positive maternal mealtime behaviours, whilst overcoming many of the limitations of previous research. Eighty-one women on low-risk maternity units gave informed consent and were visited at home at 1-week, 1-, 6- and 12-months postpartum. Infants included 45 males and 36 females (mean birth-weight 3.52 kg [SD 0.39]). Mothers and infants were weighed and measured and feeding information was recorded at each visit. Infant weight was converted to a standard deviation score (SDS), accounting for age and sex. Mothers reported infant eating behaviours at 12-months using the Children's Eating Behaviour Questionnaire and were observed feeding their infants solid food at home at 6- and 12-months. Partial correlations (covariates: maternal age, education, BMI, smoking during pregnancy, household income, infant birth weight SDS and age introduced to solid foods) revealed negative associations between breastfeeding duration and 1- to 6- and 1- to 12-month weight gain, and 6- and 12-month weight. Breastfeeding duration was also associated with a slower rate of infant eating and greater observed maternal vocalisations, appropriateness and sensitivity. Results support a dose-response relationship between breastfeeding and infant weight and suggest that breastfeeding may encourage the development of obesity-protective eating behaviours through learning to attend to internal hunger and satiety signals. Future research should investigate whether relationships between slowness in eating and weight extend to satiety responsiveness after infancy.
MCHFS showed good criterion validity with other parental report measures of eating and observations of mealtime interactions. MCHFS may be a useful tool for researching feeding problems in community samples.
Prompting a child to eat and using rewards or bargains during a positive mealtime interaction can help to overcome barriers to novel fruit consumption. Early introduction of solids is also associated with greater willingness to consume a novel fruit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
