Policonsumo de sustancias legales e ilegales en la persona mayor:

Objective: To compare the poly-consumption of legal and illegal substances among elderly residents in the cities of Medellin and Pereira (Colombia). Methodology: Quantitative, cross-sectional study, with analytical scope, which explored the demographic, social and health characteristics associated with poly-drug use, defined as the concurrent use of two or more legal and/or illegal substances. A total of 1005adults, randomly selected from their neighborhoods and homes, were surveyed through probability sampling in each city. Descriptive statistics and binomial regressionanalysis were used in the analysis, with measures of association, hypothesis testingand 95% confidence intervals. Results: The use of polypharmaceuticals was recorded in 66% of the elderly, with a higher frequency in Pereira (p<0.05). The associated demographic factors were: older than 70 years; in social: high self-esteem and perceived discrimination and health-related: experiencing pain, illness and poor sleep quality. The final model accounted for 20% of the variability observed in the use of polydrugs. Conclusions: No differences were found by city, but age, illness, and pain appear to be closely related to higher substance use; therefore, social engagement strategies and activities that promote distraction, energy expenditure, inclusion, and self-esteem are needed.
