Objective. To evaluate the prevalence and subtypes of self-reported sleep problems in women at midlife and to assess the predictive factors involved.

Methods. A total of 6408 consecutive women aged 41–55 years were recruited by sending a postal inquiry concerning health-related issues. Sleep quality was studied with the Basic Nordic Sleep Questionnaire. The effect of age, health, socioeconomic factors and use of hormone therapy (HT) on sleep problems was examined by multivariate analysis.

Results. A total of 3421 women (53%) returned the questionnaire and 42% of them reported sleep problems. Sleep problems were found in all age groups. Risk for tiredness in the morning was higher in the youngest group. Older women experienced snoring more frequently. Although somatic diseases were of minor importance, mental health was found to be a significant factor relating to almost every kind of sleep complaint. Currently employed and university educated women suffered less from poor sleep. HT use was not associated with reported sleep symptoms.

Conclusions. Self-reported sleep problems are common in midlife. A mental health problem is the most significant predisposing factor. Socioeconomic factors are also important. Use of HT does not necessarily prevent sleep problems.
