Insomnia and Psychotropic Drug Consumption


Insomnia and Psychotropic Drug Consumption

M M Ohayon et al. Prog Neuropsychopharmacol Biol Psychiatry.


1. During an epidemiological study conducted by telephone on sleep disorders in the metropolitan area of Montreal (Quebec, Canada), the authors found that 5% of subjects used psychotropic drugs. These drugs were usually prescribed by a general practitioner (72.9%). 2. From this population, the authors drew three groups of subjects: users with sleeping difficulties (USD); non users with sleeping difficulties (NUSD) and, non users without sleeping difficulties (NUWSD). 3. Results showed that the utilization of psychotropics was usually chronic and more frequent among the elderly and women. 4. In multivariate models, when users were compared to NUWSD, the authors found eight variables significantly associated with psychotropic consumption: age (> or = 55), sex (female), presence of physical illness, medical consultation, dissatisfaction with sleep onset period and sleep quantity, sleep onset period greater than 15 minutes, and to never or rarely dream. 5. When users were compared to NUSD, three variables were found to be associated with psychotropic consumption: age, to be formerly married, and to experience regular nighttime awakenings. 6. It appears that the utilization of psychotropic drugs does not increase the quality of sleep when consumers are compared to non treated insomniacs (NUSD) on parameters of sleep satisfaction.
