Sleep and emotionality in adolescents with anorexia nervosa during the Covid-19 pandemic

Abstract

Purpose: The recent Covid-19 pandemic and its lockdown measures raised concerns about people's mental health, leading to an increased interest in identifying vulnerable groups especially at risk for mental distress. This cross-sectional study investigated the impact of this unprecedented situation on sleeping patterns and emotionality in adolescents with anorexia nervosa (AN). Methods: Variations in sleeping patterns and emotionality of two groups of adolescents with AN, assessed before (N = 50) and during (N = 51) the Covid-19 lockdown were analysed. We further investigated these variations over time, considering the two lockdown periods in France. Results: Adolescents self-reported significantly more sleep difficulties and lower rates of positive emotions during lockdown, compared to those evaluated before it. Furthermore, present findings overall suggest that as the lockdown progresses, adolescents with AN show an increased deterioration of sleep quality, as indicated by greater insomnia severity levels. They also show a significant decrease in the subjective experience of positive emotionality, in particular in feelings of tenderness. Conclusions: These sleep and emotionality alterations may have amplified the severity and the incidence of AN in adolescents during the Covid-19 pandemic. These features may therefore represent therapeutic targets to optimise care of adolescents with AN. This is particularly urgent, considering kinetics of the deterioration. Tools such as those provided by cognitive behavioural therapy for insomnia and by the positive psychology framework seem appropriate to guide clinicians in this context. Level Of Evidence: Level V, descriptive study (evaluation data retrospectively studied).
