Association between use of sedatives or hypnotics, alcohol consumption, or other risk factors and a single injurious fall or multiple injurious falls: a longitudinal general population study.

In this study, we investigated the association between risk factors, including use of sedatives or hypnotics or alcohol consumption, and injurious falls leading to hospitalization or death among 4023 subjects (1828 men and 2195 women) aged 20-89 years in Stockholm County, Sweden. Questionnaire data obtained from the 1984-1985 Stockholm Health of the Population Study (SHPS) were linked to official data registers on hospitalization and mortality. Of the 4023 subjects, 330 (121 men and 209 women) had been treated for or died of injurious falls during the 12-year follow-up period. High age was significantly associated with injurious falls among both men and women. Multivariate analyses showed that women who had used sedatives or hypnotics during the 2 weeks before an injurious fall were at increased risk [relative risk of 1.83 (95% confidence interval, 1.10-3.06)] for two or more injurious falls, but not for a single fall accident. High alcohol consumption and earlier self-reported injurious falls were significantly associated with injurious falls for women younger than 60 years of age and with earlier self-reported falls and living alone for men in the same age category. Among older women (>60 years of age), high alcohol consumption and use of sedatives or hypnotics were significantly associated with injurious falls, whereas living alone and earlier self-reported accidents were significant predictors for men in the same age category. These results support a cautious prescribing policy for sedatives and hypnotics, as well as an awareness of high alcohol consumption and its association with injurious falls.
