Food Insecurity in Families With Children or Young People With Autism: A Systematic Review and Meta-Analysis

Food insecurity is frequently reported among families of children with autism spectrum conditions (ASC), yet there is limited evidence synthesising its prevalence and impact. This systematic review aimed to examine and meta-analyse the existing literature on food insecurity in families of children and young people with ASC. A comprehensive search across nine databases identified 39 papers, of which 11 met the inclusion criteria. Studies were included if they involved autistic children or young people under the age of 25 (and/or their family members) and focused on food insecurity. Eligible studies were critically appraised, and data were synthesised using both narrative and meta-analytic approaches. Meta-analyses of nine studies estimated a pooled prevalence of food insecurity at 29% (SE: 5%; 95% CI: 17%-40%; z = 5.35, p < 0.001), which increased to 31% following adjustment for publication bias. The review also found that food insecurity worsened during the COVID-19 pandemic, contributing to increased caregiver stress and disruptions in eating behaviours. This review demonstrates the high prevalence of food insecurity among families of children with ASC and the complex interplay of social, economic and behavioural challenges they face. Addressing food insecurity in autistic households requires policy responses that extend beyond financial aid to consider the sensory, behavioural and nutritional needs specific to ASC. Future research should adopt standardised measures and prioritise the development and evaluation of inclusive, tailored food support systems that reflect the lived experiences of neurodiverse families.
