Association between history of interparental violence and alcohol abuse among reproductive-age women: Evidence from the Peruvian Demographic and Health Survey

Background: Exposure to domestic violence by triggering repetitive distress and fear can affect neurodevelopmental and mental health in the short and long term. This, in turn, has been linked to an increased risk of substance abuse, such as alcohol abuse in adulthood. Objective: The present study aimed to evaluate the association between exposure to violence from the father toward the mother and alcohol abuse in Peruvian women. Design: Cross-sectional study Methods: We conducted a secondary analysis of data from the Peruvian Demographic and Family Health Survey (ENDES) of 2019. A total of 19,980 reproductive-aged women (15–49 years old) were surveyed using the Health Questionnaire during 2019. The dependent variable of the study was alcohol abuse, collected through self-report, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Intimate partner violence (IPV; violence perpetrated by the father against the mother) was considered as the exposure variable. To assess the association of interest, we only considered observations with complete data and used binary logistic regression models, calculating crude odds ratios and adjusted odds ratios (aOR). For the multivariable model, we adjusted for confounding variables (age, marital status, education level, wealth index, ethnicity, residence, current smoker, depression, and IPV). Results: We analyzed a final sample of 9953 women. The prevalence of interparental violence and alcohol abuse was 41.3% and 1.5%, respectively. We found that interparental violence was associated with higher odds of alcohol abuse (aOR: 2.10; 95% CI: 1.03–4.28) after adjusting for age, marital status, education level, wealth level, ethnicity, area of residence, current smoking, depression, and IPV. Conclusion: We identified that women of reproductive age who have been exposed to interparental violence were at higher odds of experiencing alcohol abuse issues.
