A small area analysis estimating the prevalence of addiction to opioids in Barcelona, 1993.

摘要: STUDY OBJECTIVE: To determine the distribution of opioid use prevalence in small areas and its relation with socioeconomic indicators. DESIGN: Capture-recapture was applied using data from Barcelona Drug Information System for 1993 (treatment demands, hospital emergency room visits, deaths heroin acute adverse reaction pre-trial prison admissions). avoid dependence between sources, a log-linear regression model interactions fitted. For neighbourhoods, where capture-recapture estimates were not obtainable, Heroin Problem Index (HPI) used to predict rates model. The correlation estimated by neighbourhoods their level computed. MAIN RESULTS: city's 12.9 addicts per 1000 inhabitants aged 15 44 years (95% CI: 10.1, 17.2), which represents 9176 persons. highest rate found inner city neighbourhood. Comparing obtained each neighbourhood unemployment rates, high coefficient (r = 0.80, p < 0.001). CONCLUSION: main contribution this study is that combining HPI produce area estimates, would have been possible only one method. Areas higher status showed proportionally low addiction prevalences, but depressed areas, prevalences varied widely.
