Summary: | Benzodiazepines are the most widely used psychoactive drugs, despite the risks associated with their prolonged use, especially among older adults.
To investigate the use of benzodiazepines among community-dwelling people aged ≥ 75 years.
The study was conducted among members of the baseline (in 1997) and survivors (in 2012) of the Bambuí Project cohort. The prevalence of benzodiazepine use was estimated separately for each year, and the comparison between them was performed using the Poisson regression model with robust variance.
The prevalence of benzodiazepine use was higher in 2012 (33.9%) compared to 1997 (24.9%). After multiple adjustments, the difference in prevalence did not remain significant in study population (PR = 1.25; 95%CI 0.99 - 1.60), unlike that observed in the female stratum (PR = 1.38; 95%CI 1.04 - 1.84). Clonazepam was the strongest-growing drug between the two years (PR = 4.94; 95%CI 2.54 - 9.62).
This study showed an important increase in benzodiazepine use in an older adult population. These results are concerning as these drugs are contraindicated for use in older adults, mainly if used chronically, and are available in the national list of essential medicines. Health professionals should be aware of the risks involved in its use regarding this population. |
