Women’s empowerment has a direct impact on maternal and child health care service utilization. Large scope measurement of contraceptive use in several dimensions is paramount, considering the nature of empowerment processes as it relates to improvements in maternal health status. However, multicountry and multilevel analysis of the measurement of women’s empowerment indicators and their associations with contraceptive use is vital to make a substantial intervention in the Sub-Saharan Africa context. Therefore, we investigated the impact of women’s empowerment on contraceptive use among women in sub-Saharan Africa countries. Secondary data involving 474,622 women of reproductive age (15–49 years) from the current Demographic and Health Survey (DHS) in 32 Sub-Saharan Africa region was used in this study. Contraceptive use was the primary outcome variable. Multilevel analysis was conducted to examine the impact of women’s empowerment on contraceptive use. Percentages were conducted in univariate analysis. Furthermore, multilevel logistic regression models were used to analyze the association between individual, compositional and contextual factors of contraceptive use. Results showed large disparities in the number of women who reportedly ever use contraceptive methods; this range from as low as 6.7% in Chad and as much as 72% in Namibia. More than one-third of the respondents had no formal education and more than half were active labor force. Contraceptive use was significantly more common among respondents from the richest households (28.5% versus 18.9%). Various components of women’s empowerment were positively significantly associated with contraceptive use after adjusting for demographic and socioeconomic factors. There was a significant variation in the odds of contraceptive use across the 32 countries (σ2= 1.12, 95% CrI 0.67 to 1.87) and across the neighbourhoods (σ2= 0.95, 95% CrI 0.92 to 0.98). Our findings suggest that an increase in contraceptive use and by better extension maternal health care services utilization can be achieved by enhancing women’s empowerment. Also, an increase in decision-making autonomy by women, their participation in labour force, reduction in abuse and violence and improved knowledge level are all key issues to be considered. Health-related policies should address inequalities in women’s empowerment, education and economic status which would yield benefits to individuals, families, and societies in general.

Background: The reduction of childhood malnutrition has been identified as a priority for health and development in sub Saharan African countries. The association between women’s empowerment and children’s nutritional status is of policy interest due to its effect on human development, labour supply, productivity, economic growth and development. This study aimed to determine the association between women’s empowerment and childhood nutritional status in sub Saharan African countries. Methods: The study utilized secondary datasets of women in their child bearing age (15–49 years) from the latest Demographic and Health Survey (DHS) conducted in 2011–2017 across 30 sub Saharan Africa countries. The outcome variable of the study was childhood nutritional status while the exposure variable was women’s empowerment indicators such as decision making and attitude towards violence. Analyses were performed at bivariate level with the use of chi square to determine association between outcome and exposure variables and at multivariate level with the use of regression models to examine the effect of women’s empowerment on childhood nutritional status. Results: Women’s socio-demographic and other selected characteristics were statistically significantly associated with childhood nutritional status (stunted and underweight) at p < 0.001. These characteristics were also statistically significantly associated with empowerment status of women (Decision-making, Violence attitudes and Experience of violence) at p < 0.001 except for child age and sex. The association between childhood nutritional statuses and women’s empowerment (all three empowerment measures) was significant after controlling for other covariates that could also influence childhood nutrition statuses at p < 001. Two of the empowerment measures (attitudes towards violence and experience of violence) showed positive association with childhood nutritional statuses while the third (decision-making) showed negative association. Conclusion: There is an independent relationship between childhood nutrition status and women’s empowerment in sub Saharan African countries. Women’s empowerment was found to be related to childhood nutritional status. Policies and programmes aiming at reducing childhood malnutrition should include interventions designed to empower women in Sub-Saharan Africa.

► COVID-19 has further exposed the strong association between race, ethnicity, culture, socioeconomic status and health outcomes and illuminated monumental ethnoracialised differences reflecting the 'colour of disease'. ► Racism, segregation and inequality have been invisibly and pervasively embedded in dominant cultures and social institutions for decades. ► The socioeconomic factors that negatively influence health outcomes within the underserved minority communities must be identified and contextualised within historical, political, social and economic remits. ► Acquisition of disaggregated data will be vital in identifying gaps in the social determinants of these health disparities and tailoring global policy responses.

Although ANC services are increasingly available to women in low and middle-income countries, their inadequate use persists. This suggests a misalignment between aims of the services and maternal beliefs and circumstances. Owing to the dearth of studies examining the timing and adequacy of content of care, this current study aims to investigate the timing and frequency of ANC visits in Ethiopia. Data was obtained from the nationally representative 2011 Ethiopian Demographic and Health Survey (EDHS) which used a two-stage cluster sampling design to provide estimates for the health and demographic variables of interest for the country. Our study focused on a sample of 10,896 women with history of at least one childbirth event. Percentages of timing and adequacy of ANC visits were conducted across the levels of selected factors. Variables which were associated at 5% significance level were examined in the multivariable logistic regression model for association between timing and frequency of ANC visits and the explanatory variables while controlling for covariates. Furthermore, we presented the approach to estimate marginal effects involving covariate-adjusted logistic regression with corresponding 95%CI of delayed initiation of ANC visits and inadequate ANC attendance. The method used involved predicted probabilities added up to a weighted average showing the covariate distribution in the population. Results indicate that 66.3% of women did not use ANC at first trimester and 22.3% had ANC less than 4 visits. The results of this study were unique in that the association between delayed ANC visits and adequacy of ANC visits were examined using multivariable logistic model and the marginal effects using predicted probabilities. Results revealed that older age interval has higher odds of inadequate ANC visits. More so, type of place of residence was associated with delayed initiation of ANC visits, with rural women having the higher odds of delayed initiation of ANC visits (OR = 1.65; 95%CI: 1.26–2.18). However, rural women had 44% reduction in the odds of having inadequate ANC visits. In addition, multi-parity showed higher odds of delayed initiation of ANC visit when compared to the primigravida (OR = 2.20; 95%CI: 1.07–2.69). On the contrary, there was 36% reduction in the odds of multigravida having inadequate ANC visits when compared to the women who were primigravida. There were higher odds of inadequacy in ANC visits among women who engaged in sales/business, agriculture, skilled manual and other jobs when compared to women who currently do not work, after adjusting for covariates. From the predictive margins, assuming the distribution of all covariates remained the same among respondents, but everyone was aged 15–19 years, we would expect 71.8% delayed initiation of ANC visit. If everyone was aged 20-24years, 73.4%; 25-29years, 66.5%; 30-34years, 64.8%; 35-39years, 65.6%; 40-44years, 59.6% and 45-49years, we would expect 70.1% delayed initiation of ANC visit. If instead the distribution of age was as observed and for other covariates remained the same among respondents, but no respondent lived in the rural, we would expect about 61.4% delayed initiation of ANC visit; if however, everyone lived in the rural, and we would expect 71.6% delayed initiation in ANC visit. Model III revealed the predictive margins of all factors examined for delayed initiation for ANC visits, while Model IV presented the predictive marginal effects of the determinants of adequacy of ANC visits. The precise mechanism by which these factors affect ANC visits remain blurred at best. There may be factors on the demand side like the women’s empowerment, financial support of the husband, knowledge of ANC visits in the context of timing, frequency and the expectations of ANC visits might be mediating the effects through the factors found associated in this study. Supply side factors like the quality of ANC services, skilled staff, and geographic location of the health centers also mediate their effects through the highlighted factors. Irrespective of the knowledge about the precise mechanism of action, policy makers could focus on improving women’s empowerment, improving women’s education, reducing wealth inequity and facilitating improved utilization of ANC through modifications on the supply side factors such as geographic location and focus on hard to reach women.

Background: HIV/AIDS has historically had a sex and gender-focused approach to prevention and care. Some evidence suggests that HIV-positive men have worse treatment outcomes than their women counterparts in Africa. Methods: We conducted a systematic review and meta-analysis of the effect of sex on the risk of death among participants enrolled in antiretroviral therapy (ART) programs in Africa since the rapid scale-up of ART. We included all cohort studies evaluating the effect of sex (male, female) on the risk of death among participants enrolled in regional and national ART programs in Africa. We identified these studies by searching MedLine, EMBASE, and Cochrane CENTRAL. We used a DerSimonian-Laird random-effects method to pool the proportions of men receiving ART and the hazard ratios for death by sex. Results: Twenty-three cohort studies, including 216 008 participants (79 892 men) contributed to our analysis. The pooled proportion of men receiving ART was 35% [95% confidence interval (CI): 33–38%]. The pooled hazard ratio estimate indicated a significant increase in the risk of death for men when compared to women [hazard ratio: 1.37 (95% CI: 1.28–1.47)]. This was consistent across sensitivity analyses. Interpretation: The proportion of men enrolled in ART programs in Africa is lower than women. Additionally, there is an increased risk of death for men enrolled in ART programs. Solutions that aid in reducing these sex inequities are needed.

Background Malawi is among the 5 sub-Saharan African countries presenting with very high maternal mortality rates, which remain a challenge. This study aims to examine the impact of wealth inequality and area of residence (urban vs rural) and education on selected indicators of maternal healthcare services (MHS) usage in Malawi. Methods This study was based on data from the 5th round of Multiple Indicator Cluster Surveys (MICS) conducted in 2013–2014 in Malawi. Study participants were 7572 mothers aged between 15 and 49 years. The outcome variable was usage status of maternal health services of the following types: antenatal care, skilled delivery assistance and postpartum care. Univariate, bivariate and multivariate methods were used to describe the pattern of MHS usage in the sample population. Association between household wealth status, education as well as the type of residence, whether urban or rural, as independent variables and usage of MHS as dependent variables were analysed using the generalised estimating equations (GEE) method. Results Mean age of the sample population was 26.88 (SD 6.68). Regarding the usage of MHS, 44.7% of women had at least 4 ANC visits, 87.8% used skilled delivery attendants and 82.2% of women had used postnatal care. Regarding the wealth index, about a quarter of the women were in the poorest wealth quintile (23.6%) while about 1/6 were in the highest wealth quintile (15%). Rate of usage for all 3 types of services was lowest among women belonging to the lowest wealth quintile. In terms of education, only 1/5 completed their secondary or a higher degree (20.1%) and nearly 1/10 of the population lives in urban areas (11.4%) whereas the remaining majority live in rural areas (88.6%). The rates of usage of MHS, although reasonable on an overall basis, were consistently lower in women with lower education and those residing in rural areas. Conclusions Maternal health service usage in Malawi appears to be reasonable, yet the high maternal mortality rate is disturbing and calls for analysing factors hindering the achievement of maternal health-related Sustainable Development Goals (SDGs). The findings of this study underscore the need to minimise the wealth inequality, urban–rural divide and the low level of education among mothers to improve the usage of MHS. An equity-based policy approach considering the sociodemographic inequity in terms of wealth index, education and urban–rural divide might prove beneficial in further improving the MHS usage, as well as addressing the possible issues of quality gaps in MHS, which might be beneficial towards reducing maternal mortality. It should be noted that the study of quality gaps in MHS is beyond the scope of this paper and calls for further research in this arena.
