Mental health of children and young people with pre-existing eating problems during the COVID-19 pandemic.

Abstract

Objective: The study sought to explore mental health trajectories of children and young people (CYP) who retrospectively reported eating problems prior to the pandemic, over a 2-year period (2021-23). Given the rapid increase in eating disorder presentations during the pandemic, these CYP may be particularly susceptible to pandemic-related challenges, including social and functional restrictions.

Methods: Data on 2023 CYP from the Children and Young People with Long COVID (CLoCk) study recruited Jan-March 2021 who completed questionnaires at 3-, 6-, 12-, and 24-months post SARS-CoV-2 PCR-testing were analysed. Associations between baseline eating problems (N = 241) and emotional and behavioural symptoms (measured by the Strengths and Difficulties Questionnaire (SDQ) total difficulties and impact scores) at each time-point were examined by regression models. Multi-level models were used to determine whether SDQ total and impact trajectories of those with/without prior self-reported eating problems differed.

Results: Compared to CYP who did not report pre-existing eating problems, those that did had more mental health difficulties at all time points: reflected in significantly higher SDQ total difficulties and impact scores. However, mental health scores of CYP reporting pre-pandemic eating problems were stable over time. Whereas, CYP without eating problems had a slight increase in mental health difficulties over time. Differences between groups diminished but remained significant when controlling for potential confounding variables including prior mental health difficulties.

Discussion: Young people with eating problems had more emotional and behavioural symptoms during 2021-23, compared with those that did not have eating problems. However, mental health did not worsen over time amongst CYP with pre-existing eating problems, providing evidence of some relative resilience to the effects of the pandemic in this population.

Public significance: Eating disorders are a major public health concern and presentations have remained high since the Covid-19 pandemic. Understanding how eating difficulties relate to mental health symptomology over time has implications for service planning.

Level of evidence: Level III: Evidence obtained from well-designed cohort study.
