Hormonal Contraception and Its Association With Depression

Abstract

Introduction and Aims: The aims of this study were to determine the prevalence of witnessing parental violence (WPV) during childhood and of current intimate partner violence (IPV) victimisation and aggression in a Brazilian sample in order to verify pathways between WPV and involvement in IPV as an adult. Design and Methods: The mediating roles of substance use and depression were investigated. Data came from the Second Brazilian National Alcohol and Drugs Survey a multi-cluster probabilistic household survey which gathered information on the use of psychoactive substances current depressive disorder history of childhood direct and indirect exposure to domestic violence and IPV in a nationally representative sample. A subsample of 2120 individuals aged 14 years or older was analysed. Weighted prevalence rates adjusted odds ratio and conditional path models were performed. Results: Being a victim of IPV was reported by 6% of the sample. Thus being 4.1% reported being IPV perpetrators; these rates were 16.6% and 7.3% respectively among those who reported WPV (13%). WPV was associated with being a victim of IPV in adult life but not with becoming a perpetrator regardless of being a victim of physical violence during childhood. There was a direct effect of WPV on IPV mediated by depressive symptoms. Alcohol and cocaine consumption and age of drinking initiation mediated only when combined with depressive symptoms. Discussion and Conclusions: Intergenerational transmission models of IPV through exposure during childhood can help to explain the high rates of domestic violence in Brazil. Our findings provide evidence to implement targeted prevention strategies where they are needed most: the victims of premature adverse experiences.
