Intimate partner violence and alcohol consumption

To estimate the prevalence of intimate partner violence and alcohol consumption during episodes of violence.

Cross-sectional study with a multi-stage probability sample, representative of the Brazilian population. Sample was comprised of 1,445 men and women, married or cohabitating, interviewed between November 2005 and April 2006. Interviews were conducted in the interviewees' homes, using a standardized closed questionnaire. Rates of prevalence of intimate partner violence were estimated and chi-square tests were used to assess gender differences in this prevalence.

General prevalence of intimate partner violence was 10.7% in men and 14.6% in women. Men consumed alcohol in 38.1% of cases and women in 9.2%. As regards perception of alcohol consumption by intimate partner, men reported their female partners consumed alcohol in 30.8% of episodes of violence, while women reported that their male partners consumed it in 44.6% of episodes.

Women were more frequently involved in mild and serious episodes of violence (perpetration, victimization or both) than men. The fact that episodes of violence reported were four times more frequent in intoxicated men enables the assumption that prevention of intimate partner violence may be promoted by public policies aimed at reducing alcohol consumption.
