This study examined whether self-reported tiredness in mobility and activities of daily living is predictive of mortality, when controlled for global self-rated health, smoking, and socio-demographic factors. The investigation is part of the 1984 longitudinal study of the residents of Glostrup, Denmark, born in 1914, and included 734 men and women who were interviewed about mobility, activities of daily living, self-rated health, smoking, and socio-demographic factors, when they were 70 years old. Ten years later, in November 1994, information about deaths was obtained from the Central National Register. When controlled for the other variables tiredness in mobility was an independent predictor of mortality during the next 10 years among both women and men. The finding persisted when the analysis was performed on a restricted sample of non-disabled 70-year-old people. The results in the present study indicate that we have identified a subgroup of independent elderly people who are at risk of dying earlier than others.
