[Drug and alcohol use: main findings of a national survey, Brazil 2005].
OBJECTIVE
To assess alcohol and drug use in a representative sample of the urban Brazilian population and their correlation with sexual and reproductive health.


METHODS
Data from a national population-based survey with a complex sampling, performed in 2005 was used. A total of 5,040 individuals from both genders, in the age group from 16 to 65 years old, were interviewed. Issues regarding drug and alcohol use and sexual behavior were assessed. Bivariate and multivariate analyses were used.


RESULTS
Alcohol was the most frequently used substance, with reports of regular use in the lives of 18% of interviewees. Use of illegal drugs was mentioned by 9% of the interviewees especially marijuana and snorted cocaine; injected drugs use was not frequent. There was a decrease in snorted cocaine use and an increase in marijuana use (in the last 12 months), compared to results of a similar survey conducted in 1998. History of sexual abuse was a risk factor for drug use and regular alcohol use. Interviewees mentioning the role of religion in their background, being White, and female were less likely to use alcohol in a regular way, which is especially prevalent among elderly males.Leisure activities and absence of current religious practice were associated with drug use.


CONCLUSIONS
The regular or irregular alcohol use is prevalent in the urban Brazilian population, whereas injected drug use is rare. Over the last decade there was a decline in cocaine use. A history of sexual abuse was central to later use of alcohol and drugs.
