Abstract

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic induced psychological distress, which is linked to emotional eating and symptoms of addiction to ultra-processed foods (UPFs).

OBJECTIVE

This study aimed to investigate whether symptoms of addiction to UPFs mediate the relationship between psychological stress due to the COVID-19 pandemic and emotional eating behaviour.

METHODS

A cross-sectional online study was conducted from May to November 2021 among 368 undergraduate Brazilian students. The participants answered demographic questions and completed validated scales, including the Coronavirus Stress Measure, Modified Yale Food Addiction Scale 2.0 and Emotional Eating Questionnaire. Mediation analysis was employed to examine the hypothesised relationships.

RESULTS

The results revealed a significant indirect effect, indicating that symptoms of food addiction mediated the association between perceived stress during the COVID-19 pandemic and emotional eating behaviour. Specifically, 61% of the influence of perceived stress on emotional eating during the pandemic was explained by symptoms of UPF addiction.

CONCLUSION

These findings suggest that addressing symptoms of UPF addiction could be pivotal in public health strategies aimed at promoting healthy eating habits among distressed undergraduate students in the post-COVID-19 era.

摘要

背景

2019冠状病毒病（COVID-19）大流行引发了心理困扰，这与情绪化饮食以及对超加工食品（UPF）的成瘾症状有关。

目的

本研究旨在调查对超加工食品的成瘾症状是否介导了COVID-19大流行所致心理压力与情绪化饮食行为之间的关系。

方法

2021年5月至11月对368名巴西本科学生进行了一项横断面在线研究。参与者回答了人口统计学问题并完成了经过验证的量表，包括冠状病毒压力量表、改良耶鲁食物成瘾量表2.0和情绪化饮食问卷。采用中介分析来检验假设的关系。

结果

结果显示存在显著的间接效应，表明食物成瘾症状介导了COVID-19大流行期间感知到的压力与情绪化饮食行为之间的关联。具体而言，大流行期间感知压力对情绪化饮食的影响中有61%可由超加工食品成瘾症状来解释。

结论

这些发现表明，在旨在促进COVID-19后时代困扰的本科学生养成健康饮食习惯的公共卫生策略中，解决超加工食品成瘾症状可能至关重要。
