Background: We examined differences in food selectivity by gender and parent race/ethnicity in children with intellectual disabilities. Method: A convenience sample of 56 children with intellectual disabilities was analysed. A modified Youth/Adolescent Food Frequency Questionnaire and a 3-day food record were used to measure child food refusal rate and food repertoire, respectively. Results: Boys were about twice as likely to refuse total foods (rate ratio = 2.34, 95%CI = 1.34-4.09) and fruits (rate ratio = 2.03, 95%CI = 1.04-3.95) and 54% more likely to refuse vegetables (rate ratio = 1.54, 95%CI = 0.93-2.54). Children with Hispanic parents were twice as likely to refuse vegetables compared to children with non-Hispanic White parents (rate ratio = 2.00, 95%CI = 1.03-3.90). In analyses stratified by the presence or absence of co-occurring probable autism spectrum disorder, boys had greater food selectivity than girls. Conclusions: This study expands our understanding of food selectivity in children with intellectual disabilities.
