Sleep And Positive Emotions In Adolescents With Anorexia Nervosa In Relation To The Covid-19 Pandemic

Abstract Purpose: The recent COVID-19 pandemic, and its consequent lockdown measures raised concerns about people’s mental health. Identified vulnerable groups may be especially at risk. This study investigated the impact of this unprecedent situation on sleeping patterns and emotionality in adolescents with anorexia nervosa (AN). Methods: Variations in sleeping patterns and emotionality of 101 adolescents with AN, assessed during the pandemic (Covid-19 Group), and the year before (No-Covid-19 Group) were analyzed. We further investigated these variations over time: before the lockdown, 9 months later and after the lockdown. Results: Adolescents in the Covid-19 Group had significantly higher rates of sleep alterations and lower rates of positive emotions, compared to the No-Covid-19 Group. A higher insomnia severity index score and a tendency to lengthen sleep latency time were also associated with the pandemic period. Considering three different groups of patients over time, the kinetics of the impact of the changes shows that the worsening of values is not strictly limited to the acute lockdown phase but is increasing over time. Conclusions: These sleep and emotionality features could have participated to increase severity and incidence of AN in adolescents during the Covid-19 pandemic. As such, these features could represent therapeutic targets to optimize the care of adolescents with AN, particularly urgent to improve considering the kinetic of the deterioration. Tools such as those provided by cognitive behavioral therapy for insomnia (CBTi) and by the positive psychology seem appropriate to guide clinicians in this context. Level of evidence: Level V, descriptive study (evaluation data retrospectively studied).
