Item Examining the Factors Associated With Sexual Violence Against Women in Sierra Leone: A Nationwide Cross Sectional Study(Journal of interpersonal violence, 2022) Shour, Abdul Rahman; Anguzu, Ronald; Zhou, Yuhong; Beyer, KirstenIn 2019, Sierra Leone declared national emergency over rape and other forms of sexual violence (SV), hence diverting resources from other issues to tackle SV. However, little is known about nationwide risk/protective factors for SV, and this has been a source of critique for the new policy. To fill this gap in knowledge, we investigated the factors for SV toward women using a nationally representative sample. We analyzed the 2013 Demographic and Health Survey (DHS) data, including 16,658 women, aged 15–49 years. The outcome was current SV, defined as being physically forced to have sexual intercourse within the last 12 months. We examined respondent’s background, sexual activities, and experience of domestic violence (DV). Logistic regression analyses were performed using STATA/SE v.15.1, accounting for survey design and sample weights. Values of p less than .05 were considered statistically significant. ArcMap was used to demonstrate geographic distribution of SV cases. We found that about 258 (6.3%) women reported SV. In adjusted analysis, women in the north (than south; 2.88, 95% CI = [1.44, 5.75]) and women circumcised between the ages of 1 and 14 (1.67, 95% CI = [1.10, 2.54]) reported higher risk of SV, respectively. Women who had sex more than 25 times per year were 6.9 times more likely to report SV, compared with those with 1 to 24 times (6.91, 95% CI = [1.48, 32.19]). The odds of SV were 6 times higher among women who reported experiencing recent physical violence (5.86, 95% CI = [2.49, 13.80]) or history of SV (6.34, 95% CI = [2.57, 15.65]). In conclusion, this study adds to the literature by providing information on major factors associated with SV toward women in Sierra Leone using a nationally representative sample. Women in the north (Tonkolili), circumcised between the ages of 1 and 14, had sex more than 25 times per year, reported physical violence (12 months before the survey) and SV (ever forced to have sex) reported higher risk for current SV. While more research is needed, these findings will help inform the current emergency operations against SV in Sierra Leone.Item Intimate partner violence and antenatal care utilization predictors in Uganda: an analysis applying Andersen’s behavioral model of healthcare utilization(BioMed Central Ltd, 2023-11) Anguzu, Ronald; Walker, Rebekah J; Babikako, Harriet M; Beyer, Kirsten M.M; Dickson-Gomez, Julia; Zhou, Yuhong; Cassidy, Laura DAbstract Background Optimal utilization of antenatal care (ANC) services improves positive pregnancy experiences and birth outcomes. However, paucity of evidence exists on which factors should be targeted to increase ANC utilization among women experiencing intimate partner violence (IPV) in Uganda. Objective To determine the independent association between IPV exposure and ANC utilization as well as the predictors of ANC utilization informed by Andersen’s Behavioral Model of Healthcare Utilization. Methods We analyzed 2016 Uganda Demographic and Health Survey data that included a sample of 1,768 women with children aged 12 to 18 months and responded to both ANC utilization and IPV items. Our outcome was ANC utilization, a count variable assessed as the number of ANC visits in the last 12 months preceding the survey. The key independent variable was exposure to any IPV form defined as self-report of having experienced physical, sexual and/or emotional IPV. Covariates were grouped into predisposing (age, formal education, religion, problem paying treatment costs), enabling (women’s autonomy, mass media exposure), need (unintended pregnancy, parity, history of pregnancy termination), and healthcare system/environmental factors (rural/urban residence, spatial accessibility to health facility). Poisson regression models tested the independent association between IPV and ANC utilization, and the predictors of ANC utilization after controlling for potential confounders. Results Mean number of ANC visits (ANC utilization) was 3.71 visits with standard deviation (SD) of ± 1.5 respectively. Overall, 60.8% of our sample reported experiencing any form of IPV. Any IPV exposure was associated with lower number of ANC visits (3.64, SD ± 1.41) when compared to women without IPV exposure (3.82, SD ± 1.64) at p = 0.013. In the adjusted models, any IPV exposure was negatively associated with ANC utilization when compared to women with no IPV exposure after controlling for enabling factors (Coef. -0.03; 95%CI -0.06,-0.01), and healthcare system/environmental factors (Coef. -0.06; 95%CI -0.11,-0.04). Predictors of ANC utilization were higher education (Coef. 0.27; 95%CI 0.15,0.39) compared with no education, high autonomy (Coef. 0.12; 95%CI 0.02,0.23) compared to low autonomy, and partial media exposure (Coef. 0.06; 95%CI 0.01,0.12) compared to low media exposure. Conclusion Addressing enabling and healthcare system/environmental factors may increase ANC utilization among Ugandan women experiencing IPV. Prevention and response interventions for IPV should include strategies to increase girls’ higher education completion rates, improve women’s financial autonomy, and mass media exposure to improve ANC utilization in similar populations in Uganda.Item Parish level social factors predict population-based cervical cancer incidence in Kampala, Uganda, 2008–15: an ecological study(The Lancet Global Health, 2022) Beyer, Kirsten M M; Kasasa, Simon; Anguzu, Ronald; Nambooze, Sarah; Amulen, Phoebe Mary; Nansereko, Brendah; Zhou, Yuhong; Lukande, Robert; Wabinga, HenryThe burden of cancer in Africa is growing. Although cancer outcomes are understood as the product of influences at multiple socioecological levels, population-based studies of geographical factors and cancer outcomes in Africa are scarce. The objective of this study was to identify parish-level social factors associated with cervical cancer incidence in the Kampala Cancer Registry catchment area, using a novel linkage between population-based cancer registry data and small-area census data from Uganda. Kampala Cancer Registry cervical cancer records (2008–15) were augmented to add the parish of residence at diagnosis. Parish-level population and housing profile data (2014) were obtained from the Uganda Bureau of Statistics and linked to Kampala Cancer Registry records. Stepwise forward Poisson regression modelling was used to estimate incidence ratios (IR) assessing associations between social factors and incidence. Housing tenure, infrastructure, gender equality, economic status, and employment were examined, controlling for population density. The significance level was set at α=0·05. Factors related to higher incidence included a higher girl-to-boy ratio of 6–12-year-olds not attending school (IR 1·33 [95% CI 1·15–1·54]; p<0.001), a higher percentage of 10–17-year-olds ever married (IR 1·22 [95% CI 1·06–1·40]; p=0·006) and a higher percentage of households receiving remittances (IR 1·03 [95% CI 1·00–1·06]; p=0·026). Factors associated with lower incidence included a higher percentage of household owner occupancy (IR 0·95 [95% CI 0·92–0·98]; p=0·002) and a higher percentage of households with piped water (IR 0·97 [95% CI 0·95–0·99]; p=0·009). Interpretation Parish-level social factors predict cervical cancer incidence in Uganda. Communities most at risk are characterised by inequity in educational access for girls, higher prevalence of child marriage, low home ownership, inadequate infrastructure, and financial dependence. These communities would benefit from HPV vaccination and screening campaigns to prevent and control cervical cancer. Investments should be made to enhance population-based cancer surveillance and census data collection in Africa to offer new strategies and targets for cancer prevention and control.
