Annotation	In 1983, a sample of 1,870 Swedes aged 45-65 answered a questionnaire on sleep and health. Of the 1,604 survivors in 1995, 1,244 (77.6%) answered a new questionnaire with almost identical questions. Mortality data were collected for the 266 who had died in the follow-up period. Chronic insomnia was reported by 36% of women and 25.4% of men. About 75% of those with insomnia at baseline continued to have insomnia at follow-up. Insomnia in women predicted subsequent depression, but was not related to mortality. In men, insomnia predicted mortality, but after adjustment for an array of possible risk factors, this association was no longer significant. Men with depression at baseline had an adjusted total death rate that was 1.9 times higher than in the non-depressed men. (RH).
