Introduction Intimate partner violence is increasingly gaining attention as the leading form of violence against women globally, particularly sub-Saharan Africa. Given that substance abuse, especially alcohol consumption has long been associated with aggressive behaviour, emotional abuse, and sexual misconduct, it is surprising that studies on the potential association between partner’s alcohol consumption and intimate partner violence are scarce. The current study seeks to fill this gap in the literature by examining the association between partner’s alcohol consumption and intimate partner violence among women in sub-Saharan Africa. Methods Cross-sectional survey data of 89,229 women aged 15 to 49 in sexual unions from 21 sub-Saharan African countries were pooled from the Demographic and Health Surveys. Percentages with their corresponding confidence intervals (CIs) were used to present the results of the prevalence of partner’s alcohol consumption and intimate partner violence. Multivariable binary logistic regression analysis was used to examine the association between partner’s alcohol consumption and intimate partner violence. The regression analysis results were presented using adjusted odds ratio (aOR) with 95% CI. Statistical significance was set at p<0.05. Results The pooled prevalence of partner alcohol consumption was 36.3% [36.0–36.6]. The highest prevalence of partner alcohol consumption was found in Burundi (67.1%) with Mali (3.9%) recording the lowest prevalence. Similarly, the overall prevalence of physical violence, emotional violence, and sexual violence among the women were 19.7% [19.2–20.2], 25.0% [24.5–25.5], and 9.7% [9.3–10.1], respectively. In the pooled data, women whose partners consumed alcohol were more likely to experience physical violence [aOR = 2.37, 95% CI = 2.24–2.50], emotional violence [aOR = 1.96, 95% CI = 1.86–2.07], and sexual violence [aOR = 2.03, 95% CI = 1.89–2.18] compared to those whose partners did not consume alcohol. In all the 21 countries, women whose partners consumed alcohol had higher odds for physical and emotional violence. The odds of sexual violence was higher among women whose partners consumed alcohol compared to their counterparts whose partners did not in 20 countries, except Namibia. Conclusions We found that partner’s alcohol consumption increases women’s likelihood of experiencing physical, emotional, and sexual violence in sub-Saharan Africa. There is the need to implement behavioural change interventions targeted at male partners to reduce alcohol consumption. The findings call for the need to effectively create and organize support networks in addressing intimate partner violence among married and cohabiting women.

Background Given the instrumental role long-acting reversible contraceptives (LARCs) play in reducing unintended pregnancies, there is a need to understand the factors that predict their use among adolescent girls and young women in high fertility countries. Our study examined the prevalence and predictors of LARCs use among adolescent girls and young women in high fertility countries in sub-Saharan Africa. Materials and methods We pooled data from the women’s files of the most recent Demographic and Health Surveys (DHS) from 2010 to 2020 of the top ten high fertility countries in sub-Saharan Africa, which are part of the DHS programme. The total sample was 5854 sexually active adolescent girls and young women aged 15–24 who were using modern contraceptives at the time of the survey. Descriptive and multilevel logistic regression models were used in the analyses. The results were presented using percentages and adjusted odds ratio (AOR) with their respective 95% confidence intervals (CIs). Results At the descriptive level, the overall prevalence of LARCs utilisation was 17.6% in the ten countries, with the lowest of 1.7% in Angola and the highest of 55.8% in Mali. Adolescent girls and young women who were married had a lower likelihood of LARCs utilisation than those who were never married [AOR = 0.63, 95% CI = 0.45, 0.88]. Adolescent girls and young women who wanted no more children had higher odds of LARCs use compared to those who wanted more children [AOR = 1.56, 95% CI = 1.09, 2.26]. Adolescent girls and young women with one to three births [AOR = 6.42, 95% CI = 4.27, 9.67], and those with four or more births [AOR = 7.02, 95% CI = 3.88, 12.67] were more likely to use LARCs compared to those who had no children. Countries in sub-Saharan Africa with lower probability of utilizing LARCs were Angola, Niger and Mozambique, whereas adolescent girls and young women in Mali had higher probability of utilizing LARCs. Conclusion Our findings suggest that LARCs utilisation among adolescent girls and young women is low in high fertility countries in sub-Saharan Africa. To reduce the rates of unplanned pregnancies and induced abortions, it is imperative that adolescent girls and young women in sub-Saharan Africa are educated on the advantages of utilising LARCs. Additionally, governments, policymakers, and stakeholders in sub-Saharan Africa should raise awareness by executing health promotion measures to enhance the demand for LARCs among adolescent girls and young women. Achieving these would not only prevent unplanned pregnancies and induced abortions, but also help meet the United Nation’s health and well being for all as enshrined in Sustainable Development Goals 3 and 5.
