Study identifies specific work factors that predict sleep problems

Specific psychological and social work factors were associated with sleep problems both concurrently and two years after exposure, indicating prolonged consequences, new research suggests. Results show that quantitative job demands, decision control, role conflict and support from a superior in the workplace were the most consistent predictors of troubled sleep, which was characterized by difficulty initiating sleep or disturbed sleep. Findings remained significant after adjustment for potential con-founders such as age, sex and occupation skill level.
