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 studyMethods: 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. Understanding the link between witnessing parental violence and alcohol abuse in Peruvian womenWitnessing violence between parents during childhood can leave deep emotional scars. This study explores whether such experiences are related to alcohol abuse among Peruvian women in their adult years. Using data from a national health survey in Peru, the experiences of nearly 20,000 women were analyzed to determine if witnessing violence between their parents during childhood was linked to alcohol problems later in life. Responses from the 2019 Peruvian Demographic and Family Health Survey were examined, focusing on women's reports of childhood exposure to violence between parents and current alcohol abuse, controlling for factors like age, education, and mental health. The study found that women who witnessed their parents engaging in violence were more likely to abuse alcohol as adults. About 41% of the women reported seeing such violence, and of these, a higher proportion struggled with alcohol compared to those who did not witness violence. Understanding the link between childhood experiences and adult behaviors can help develop targeted interventions to prevent alcohol abuse. This research highlights the need for support systems that help women cope with the emotional impacts of childhood trauma, potentially reducing alcohol-related problems in the future.
