COVID-19 and Food-Related Outcomes in Children with Autism Spectrum Disorder: Disparities by Income and Food Security Status

A majority of caregivers reported negative impacts on food availability and eating behaviors in their children with autism spectrum disorder post-onset of COVID-19. The impact experienced was greater among low-resource families. Background Limited research suggests increased adverse behavioral outcomes, such as distractibility and hyperactivity, among children with autism spectrum disorder (ASD) as a result of coronavirus 2019 (COVID-19); however, little is known about how the pandemic has impacted food-related behaviors among children with ASD. Objective This study characterizes the impact of the pandemic on access to preferred foods and eating behaviors among children with ASD. Methods Caregiver proxies (n = 200) participated in a cross-sectional, online survey investigating the impact of COVID-19 on reported food and eating behaviors of children, ages 2-17 y. Logistic regression models were used to assess the magnitude of association of a change in the child's eating behaviors and in food availability, overall and by household income and food security status. Results A majority of respondents reported a moderate-to-large impact on their child's eating behaviors (57%) since the onset of COVID-19, and 65% reported unavailability of their child's preferred foods. Increased risk of a moderate-to-large impact on children's eating behaviors was associated with shelter regulations compared with no regulations (OR: 2.30; 95% CI: 1.12, 4.72), food insecurity compared with security status (OR: 2.60; 95% CI: 1.45, 4.67), and household income of <$50,000 compared with >=$100,000 (OR: 2.33; 95% CI: 1.02, 5.29). The pandemic also amplified the risk of food unavailability by household food security status (food insecure vs. secure; OR: 4.13; 95% CI: 2.12, 7.69) and across income levels (<$50,000 vs. >=$100,000; OR: 3.48; 95% CI: 1.42, 8.55; and $50,000 to <$100,000 vs. >=$100,000; OR: 4.00; 95% CI: 1.71, 9.34). Reported frequencies of consumption of meat, seafood, vegetables, and 100% fruit juice significantly decreased among the children post-onset of COVID-19, while frequency of consumption of sweets increased. Conclusions A large proportion of caregivers reported substantial COVID-19 impacts on food availability and eating behaviors of children with ASD, especially among low-resource dyads. This study highlights the added burden of existing disparities due to the pandemic on children living with ASD.

Automated summary

The COVID-19 pandemic has had a negative impact on food availability and eating behaviors among children with autism spectrum disorder, especially in low-resource families. Existing disparities have been exacerbated by the pandemic for children living with ASD.
