Feeding and eating disorders in children and adolescents during the COVID-19 pandemic: real-word data from an observational, naturalistic study

BACKGROUND: The COVID-19 pandemic had a substantial impact on the mental health of children and adolescents. The literature lacks large-scale research evaluating its consequences on teenagers with feeding and eating disorders (FED). This study aims to assess the impact of the COVID-19 pandemic on a population of patients of developmental age. METHODS: This single-center observational study compares two historical cohorts of children and adolescents diagnosed with FED, with a first consultation before (1st March 2018 to 31st October 2019) and during (1st March 2020 to 31st October 2021) pandemic. Demographic, clinical, nutritional, and treatment variables were assessed. RESULTS: We enrolled 479 patients (F=398, 83.1%), including 205 (F=161, 78.5% mean age 14.5±2.5, range 7.9-17.9 years) belonging to the first historical cohort and 274 (F=237, 86.5%; 14.4±2.1, range 6.5-17.9) to the second one (+33.7%). Increased mean new accesses/month (P=0.042) and a greater percentage of females (P=0.042) during the pandemic compared to the pre-pandemic period emerged. Physical hyperactivity (P=0.022) and suicidal behaviors (P=0.030) increased, while fewer patients required hospitalization (P=0.013). CONCLUSIONS: An increase in first visits for FED after the COVID-19 pandemic emerged, with females being the most affected. Physical hyperactivity and self-harming behaviors were intensified, while patients in need of hospitalization were reduced. Longitudinal studies are required.
