Long-term use of benzodiazepines in a Swedish community: an eight-year follow-up.
Use of benzodiazepines in a Swedish community with a general population of about 20,000 was studied using data from a research registry on prescriptions. A cohort of all benzodiazepine users in 1976, aged 15-84 years, was identified and followed for 8 years with respect to continued benzodiazepine use. A strong tendency towards continuous use was observed. Nearly 70% of the cohort continued use of benzodiazepines during the first follow-up year, 56% used benzodiazepines during the second year as well. One third continued using benzodiazepines during all 8 years of follow-up. Heavy use, previous use of benzodiazepines and age were of great importance for predicting long-term use while sex and type of benzodiazepine were of minor importance. However, after 3 or 4 years of use the pattern was very much the same in all subgroups, about 90% of users continued irrespective of user characteristics.
