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

ABSTRACT:

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.

Project description:ImportanceThe prevalence of autism spectrum disorder (ASD) in US children has increased during the past decades. Immunologic dysfunction has recently emerged as a factor associated with ASD. Although children with ASD are more likely to have gastrointestinal disorders, little is known about the association between food allergy and ASD.ObjectiveTo examine the association of food allergy and other allergic conditions with ASD in US children.Design, setting, and participantsThis population-based, cross-sectional study used data from the National Health Interview Survey collected between 1997 and 2016. The data analysis was performed in 2018. All eligible children aged 3 to 17 years were included. Food allergy, respiratory allergy, and skin allergy were defined based on an affirmative response in the questionnaire by a parent or guardian.Main outcomes and measuresReported ASD diagnosed by a physician or other health professional.ResultsThis analysis included 199 520 children (unweighted mean [SD] age, 10.21 [4.41] years; 102 690 boys [51.47%]; 55 476 Hispanic [27.80%], 97 200 non-Hispanic white [48.72%], 30 760 non-Hispanic black [15.42%], and 16 084 non-Hispanic other race [8.06%]). Among them, 8734 (weighted prevalence, 4.31%) had food allergy, 24 555 (12.15%) had respiratory allergy, and 19 399 (9.91%) had skin allergy. A diagnosis of ASD was reported in 1868 children (0.95%). The weighted prevalence of reported food, respiratory, and skin allergies was higher in children with ASD (11.25%, 18.73%, and 16.81%, respectively) compared with children without ASD (4.25%, 12.08%, and 9.84%, respectively). In analyses adjusting for age, sex, race/ethnicity, family highest education level, family income level, geographical region, and mutual adjustment for other allergic conditions, the associations between allergic conditions and ASD remained significant. The odds ratio (OR) of ASD increased in association with food allergy (OR, 2.29; 95% CI, 1.87-2.81), respiratory allergy (OR, 1.28; 95% CI, 1.10-1.50), and skin allergy (OR, 1.50; 95% CI, 1.28-1.77) when comparing children with these conditions and those without.Conclusions and relevanceIn a nationally representative sample of US children, a significant and positive association of common allergic conditions, in particular food allergy, with ASD was found. Further investigation is warranted to elucidate the causality and underlying mechanisms.
