How eating habits change by sex in autistic children and young adults

Sex Informed Profiles of Eating Behaviors in Autism Across Childhood and Young Adulthood

NIH-funded research Univ of North Carolina Chapel Hill · NIH-11252289

This project looks at different eating patterns in autistic children, teens, and young adults to understand how they change with age and differ between males and females.

What this research studies

Researchers are combining data from four existing groups of autistic and non-autistic people, enriched for females and spanning about ages 4 to 39, to identify types of eating behaviors like food selectivity, refusal, and neophobia. They will use harmonized eating-behavior measures already collected in those cohorts to create behavior profiles and link those profiles to later clinical outcomes, including eating disorder diagnoses. The work relies on longitudinal data so patterns can be followed over time rather than from single visits. The aim is to clarify how age and sex shape restrictive or disordered eating in autism to inform future care.

Who could benefit from this research

Good fit: People with autism across childhood, adolescence, and young adulthood (roughly ages 4–39), and their caregivers who can report on eating behaviors, are most relevant to this project.

Not a fit: People without autism, older adults beyond the studied age range, or individuals whose eating issues come from non-autism causes may not directly benefit from these findings.

Why it matters

Potential benefit: If successful, this work could help identify autistic people at higher risk for severe restrictive eating or eating disorders earlier and guide more personalized prevention and care.

How similar studies have performed: Prior studies have documented elevated restrictive eating and eating disorders in autism, but pooling harmonized longitudinal data across multiple cohorts to create sex-informed profiles is a relatively new approach.
