Risk factors for insomnia and burnout: A longitudinal population‐based cohort study

Abstract

AbstractInsomnia and burnout are highly prevalent in the general population, calling for understanding of its causes. Taking a broad approach, the aim of this study was to determine various mental and somatic risk factors for development of insomnia and burnout and stratifying for sex and age group. Questionnaire data were used from a Swedish population‐based sample aged 18–79 years, from which cohorts without insomnia (n = 1702) and without burnout (n = 1972) at baseline were followed‐up after 3 years. Self‐reports of eight mental and somatic conditions at baseline were used as independent variables in logistic regression analyses to predict development of insomnia and burnout at 3‐year follow‐up. All eight studied conditions were significant risk factors for development of both insomnia (odds ratio, OR = 1.62–2.73) and burnout (OR = 2.20–3.21). Burnout and poor self‐rated health had the highest ORs for insomnia, and poor self‐rated health, anxiety and somatic symptoms had the highest ORs for burnout. The ORs were generally similar between men and women, whereas age groups tended to differ in some of the risk factors. The study highlights the importance of a broad assessment of both mental and somatic conditions in the prevention of insomnia and burnout.
