Association between change in suicidal ideation, and distinct symptoms of depression and sleep changes during COVID-19.

COVID-19 has created a situation that has never been experienced before, challenging the mobilization of adaptive coping strategies. There has been a marked increase in suicides and suicidal ideation following the onset of COVID-19 likely reflecting the toll of the pandemic on mental health. The aim of our study to investigate the associations between depressive symptoms and distinct symptom clusters and lifestyle changes related to sleep, eating and physical activity and change in suicidal thoughts and thinking about death during the pandemic. Analyses involved data from the Hungarian part of the COMET-G (COVID-19 Mental health in Ternational for the General population) study, including 763 Hungarian adults, who completed a detailed questionnaire focusing on changes in behavior, lifestyle, activity and mental health during the pandemic. The dataset was analyzed using ordinal regression models adjusted for age and sex. Depression, as well as its symptom clusters, including anhedonia and depressed mood and somatic complaints had a significant, but small effect increasing suicidal ideation, while the effect of irritability and social relationship problems was more marked. In case of lifestyle factors no associations was found between change in eating habits or physical activity and change in suicidal ideations, however, sleeprelated changes were associated with a significant increase in suicidal thoughts during the pandemic. Our findings show that not all symptoms related to mood disturbance have an equally marked effect on suicidal ideating and thus suicide risk, emphasizing the role of detailed screening and evaluation even in subclinical populations in times of such crises, and also highlight the importance of considering sleep problems when evaluating suicide risk. Thus, our findings help identify relevant targets for screening and intervention in decreasing suicide risk during crises. (Neuropsychopharmacol Hung 2022; 24(3): 134-143).
