Methods: Nigerian COVID-19 patients (n=498) aged 18 years and above completed an online survey that consisted of sociodemographic and illness-related details, the Insomnia Severity Index (ISI), the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-8), suicidal ideation (item 9 of the PHQ-9) and the Brief Symptoms Rating Scale (BSRS-5).
Results: Insomnia of varying degrees was present in 22.5%. Hierarchical linear regression analysis showed that the combination of psychological distress, suicidal ideation, and duration of self-isolation were significantly associated with insomnia (accounts for 86% of the variance on ISI scores).
Conclusions: Our study revealed that insomnia is relatively common among the mildly symptomatic COVID-19 Nigerian adult patients. The associated factors may serve as a template for the development of insomnia improving interventions for mildly symptomatic Nigerian COVID-19 patients.
