Prevalence of intimate partner violence and associated factors: A population-based study in Lages, Santa Catarina State, Brazil, 2007

Abstract

The aim of this study was to estimate the prevalence of intimate partner violence and associated factors in Lages, Santa Catarina State, Brazil. A population-based household study included 20-59-year-old women (n = 1,042) living in the urban area. The Conflict Tactics Scales - Form R was used to investigate verbal aggression, minor physical violence, and severe physical violence. A questionnaire covering socioeconomic and demographic variables was applied. Pearson qui-square and linear trend test were used to test associations. Prevalence rates for verbal aggression and minor and severe physical abuse within couples were 79.0%, 14.9%, and 9.3%, respectively. Couples under 30 years of age, with per capita income less than half the minimum wage (approximately U$90/month), and in households with more than two family members per bedroom were more likely to report all types of violence as compared to older couples, those with better incomes, and those living with less crowding, respectively. Preventive programs and qualitative studies could be effective strategies to shed further light on intimate partner violence.
