Abstract

The abuse of multiple substances continues to be a major public health concern in the United States, Latin America and other countries in the world. Recent studies have revealed that polydrug use has increased in many European countries. The main objective of this study was to determine the patterns of polydrug use in several Latin American countries. The data for this study was derived from separate studies conducted in Argentina, Bolivia, Chile, Ecuador, Uruguay and Perú. In each country a household survey was conducted using a multistage, stratified, cluster sample design. In all six countries, probabilistic samples of household residents aged 12 to 65 years of age were selected in three stages. The data were collected by a face to face interview using the same structured questionnaire, which was based on the Inter-American Uniform Drug Use Data System (SIDUC). A multivariate ordinal logistic regression model was fitted to assess the effects of country of origin on polydrug use, after adjusting for age and gender. The overall prevalence of polydrug use was 21%. The multivariate ordinal logistic regression model showed that males, participants aged 18 to 34 years and those from Chile, Uruguay and Argentina were significantly more likely to be polydrug users after adjusting for age and sex. This is the first study that documents the burden of polydrug use in Latin American countries. Future epidemiological studies should be conducted to examine the relationship between other demographic characteristics and risk behaviors with patterns of polydrug use.
