Ultra-processed foods and metabolic health in children and teens

The UFO (Ultra Processed Foods in Obesity) Project

Observational Federico II University · NCT05554016

This project will try to see if eating more ultra-processed foods is linked to obesity and metabolic syndrome in children and adolescents aged 6–18.

What this trial studies

The UFO Project is an observational study that compares ultra-processed food (UPF) intake across three pediatric groups: children with obesity, children with obesity plus metabolic syndrome, and age- and sex-matched healthy controls. Participants are Caucasian boys and girls aged 6–18 recruited at the University of Naples Federico II and will have dietary assessments alongside clinical evaluation of metabolic syndrome components. The study uses cross-sectional analyses to look for associations between UPF consumption patterns and metabolic risk markers without assigning any interventions. Findings will be based on clinical and dietary data collected during clinic visits.

Who should consider this trial

Good fit: Ideal candidates are Caucasian children and adolescents aged 6–18 who either have obesity, have obesity with metabolic syndrome, or are healthy age- and sex-matched controls and meet the study's exclusion criteria.

Not a fit: Children outside the 6–18 age range, non‑Caucasian individuals, or those with chronic diseases, recent antibiotic/probiotic use, recent gastrointestinal illness, or other listed exclusions are unlikely to receive benefit from participation.

Why it matters

Potential benefit: If successful, the project could identify dietary patterns tied to higher metabolic risk in children and help shape prevention and public health guidance.

How similar studies have performed: Previous observational studies in adults and children have linked higher UPF intake to obesity and metabolic risk, but causal evidence—especially in pediatric populations—is still limited.
