# Ultra-processed food addiction symptoms profile according to weight status among Brazilian adults

## TL;DR

The study found that symptoms of ultra-processed food addiction worsen with higher body weight in Brazilian adults, suggesting a link between weight status and addiction severity.

## Contribution

The study identifies distinct symptom profiles of ultra-processed food addiction that vary with different weight categories.

## Key findings

- UPF addiction symptoms like social harm and role interference increased with higher BMI.
- Symptom severity showed a progressive rise across different obesity classifications.
- Adjustments for age, sex, and mental health diagnoses confirmed the BMI-symptom link.

## Abstract

The study aimed to investigate several ultra-processed food (UPF) addiction symptoms according to the weight status and to verify if there are specific symptoms of UPF addiction that differ according to the weight status in adults with a UPF addiction diagnosis.

This is a cross-sectional study that included adults (18–59 years) of both sexes with UPF addiction diagnosis. Demographic and clinical data were collected, such as body mass index (BMI), diagnosis of depression, and generalized anxiety disorder (GAD). UPF addiction was assessed using the modified Yale Food Addiction Scale 2.0.

In total, 1,074 participants were included. Of this total, 83.3% (n = 895) were female, with a mean age of 23 ± 5 years, of which 36.8% (n = 395) were classified with normal weight, 31.9% (n = 343) with overweight, 19.5% (n = 209) with obesity I, 8.1% (n = 87) with obesity II, and 3.7% (n = 40) with obesity III. The prevalence of UPF addiction symptoms referring to social/interpersonal harm, cut down/quit, role interference, and physical/psychological harm increased progressively with increasing BMI, even after adjusting for age, sex, diagnosis of depression, and GAD.

This study showed a progressive increase in UPF addiction symptom severity with rising BMI levels. Moreover, distinct UPF addiction symptom profiles emerged across various BMI categories. Understanding these nuances can guide the development of targeted interventions and treatment strategies to address this multifaceted behavioral profile effectively. Further research across different populations is imperative to broaden our comprehension of UPF addiction’s impact and expression.
