[Factors associated with short- and long-term use of benzodiazepines in the elderly from Quebec]. / Facteurs associés à la consommation de courte et de longue durée des benzodiazépines chez les personnes âgées du Québec.

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.

[Anxiolytic, sedative and hypnotic medication use in the elderly living in the community: Developing a conceptual framework]. / Utilisation des anxiolytiques, sédatifs et hypnotiques chez les personnes âgées vivant dans la communauté: construction d'un cadre conceptuel.

Inappropriate consumption of anxiolytic, sedative and hypnotic medication (ASH) in the elderly is an important public health issue. Almost 35 % of the elderly population living at home take these medications, approximately 206 days per year. According to Quebec data, people who are 65 and older take five times more ASH than people between 18 and 64. The use of ASH would not only be determined by the presence of symptoms, but also by psychosocial characteristics of the subjects. Moreover, several researchers have suggested that the family as well as the health system were environmental factors that could facilitate or inhibit consumption of these medications in the elderly. A conceptual framework is proposed to help specify more adequately the various explanatory hypotheses of this social health behavior and, consequently, better target interventions aiming at its modification.

Factors associated with long-term benzodiazepine use among elderly women and men in Quebec.

The goal of this study was to compare factors associated with long-term benzodiazepine use by elderly women and men (n = 1701) who participated in the Quebec Health Survey (QHS). Data from the 1998 QHS were linked with data from the administrative files of the Régie de l'assurance maladie du Québec. Results showed that elderly women were more at risk than men for long-term benzodiazepine use. Results of the multivariate logistic regression did not show a significant difference between women and men on any of the risk factors studied. Other factors such as elderly and physician attitudes deserve further study to explain differences in long-term benzodiazepine use between elderly women and men.
