In Quebec, benzodiazepines are some of the most extensively used drugs by the elderly. The goal of this study was to identify factors associated with short- and long-term benzodiazepine use among 2,039 elderly persons having participated in the Quebec Health Survey conducted in 1998. Results of the multivariate, multinomial logistic regression showed that a higher number of chronic health problems, a higher number of physicians visited and general practitioners consulted were associated with short- and long-term use of benzodiazepines. Factors specifically associated with long-term use were female gender (OR = 1.84) and the presence of benzodiazepine users in the household (OR = 1.90). In this study, we were unable to show a difference between the two groups of users with regards to the risk factors studied. This result leads us to conclude that prevention of long-term use must be aimed at all new benzodiazepine users.
