Association between male absence and women’s reproductive autonomy in sub-Saharan Africa
Reproductive decision-making within partnered relationships in sub-Saharan Africa (SSA) is often shaped by patriarchal gender norms, with male partners commonly exerting substantial influence over family planning and contraception. These dynamics may shift when male partners migrate and are not physically present in the household. This study investigates the association between male absence and women’s reproductive autonomy in SSA, using national…
Mapping the evidence on factors influencing postpartum contraception among sub-Saharan African immigrant and refugee women in the United States
BACKGROUND: The postpartum period is a critical window for addressing women's contraceptive needs. Sub-Saharan African immigrant and refugee women living in the United State face unique barriers to postpartum contraception due to cultural norms, religious beliefs, migration-related challenges, and systemic inequalities, yet there is limited evidence on their postpartum contraceptive preferences and use. This scoping review mapped the existing lit…
Scars of birth
BACKGROUND: A single multi-country study in sub-Saharan Africa (SSA) conducted nearly two decades ago reported that caesarean section (C-section) delivery was associated with reduced subsequent childbearing. To address the gap created by the lack of recent regionally representative evidence that reflects changes in access to surgical delivery, maternal health systems, and fertility-related attitudes, we assessed the association between having eve…
Enhancing malaria-in-pregnancy monitoring
Malaria in pregnancy (MiP) is a significant public health concern in high-burden malaria countries and a key predictor of high-risk pregnancies in Cameroon. One of the challenges of the National Malaria Control Programme (NMCP) in Cameroon is to generate reliable, timely, accurate and actionable data to inform decision-making, effective monitoring and planning. Discussions with the NMCP at the Ministry of Public Health (MoPH) identified poor data…
Associations between water insecurity and reproductive health outcomes among adolescent girls and young women in Sub-Saharan Africa

Water insecurity may contribute to these vulnerabilities by creating social and environmental stressors that undermine reproductive health and rights, yet this relationship remains understudied. This study examined associations between water insecurity and reproductive health outcomes among AGYW in 29 SSA c…
Malnourished Child, Overweight Mother? Examining the Double Burden of Malnutrition in Sub‐Saharan Africa
The double burden of malnutrition (DBM) - the coexistence of child undernutrition and maternal overweight/obesity - within the same household is a growing public health challenge in sub-Saharan Africa (SSA). This study assessed the prevalence and determinants of DBM at the household level across 22 SSA countries using recent nationally representative Demographic and Health Survey (DHS) data from 103,497 mother-child under-five pairs. Outcomes inc…
Breaking the Cycle
Stunting, largely established during the first 1000 days of life, remains a major public health challenge in sub-Saharan Africa, contributing to early-life deficits and perpetuating intergenerational disadvantage. Children born to stunted mothers are at increased risk of experiencing stunting themselves, reflecting the persistence of nutritional vulnerability across generations. This study examines the association between maternal and child stunt…
The shadow of violence
Despite increasing efforts to improve reproductive health outcomes in sub-Saharan Africa (SSA), disparities persist in the use of modern contraceptives and maternal health services (MHS). Evidence suggests that exposure to intimate partner violence (IPV) may influence women’s health-seeking behaviours, yet few studies have examined this relationship across multiple SSA countries. Using cross-sectional data from the most recent Demographic and Hea…

This study investigates the associations between trajectories of family adversity and poverty during …
Impact of unconditional cash transfers on household livelihood outcomes in Nigeria
In 2018, Nigeria began the implementation of a cash transfer programme (CCT) for poor and vulnerable people. We evaluated the impact of cash transfer on household livelihood outcomes in Nigeria. Using multistage cluster sampling methodology, beneficiaries and non-beneficiaries within the same locality were randomly selected to participate in a survey to assess the impact of cash transfer on food security and food diversity.When gender, marital st…
Engaging Community Health Workers (CHWs) in Africa
Universal Health Coverage (UHC) will not be achieved if health care worker shortages, estimated to increase to 18 million by 2030, are not addressed rapidly. Community-based health systems, which pivot to effective engagement of community health workers (CHW), may have an essential role in linking communities with health care facilities and reducing unmet health services needs caused by these shortages. The Canadian Red Cross (CRC) has partnered …
Prevalence and health consequences of nonmedical use of tramadol in Africa
Tramadol is a widely prescribed painkiller around the world. As a synthetic opioid, it offers a valuable substitute for morphine and its derivatives in African countries. However, the adverse health effects of tramadol use resulting from illicit trafficking, like those caused by fentanyl and methadone in North America, have not been well-documented in Africa. This scoping review aims to shed light on the nature and scope of the nonmedical use (NM…
Using the Family Planning Estimation Tool (FPET) to assess national-level family planning trends and future projections for contraceptive prevalence and associated demand for HIV-infected women in sub…
The combination of low uptake of modern contraceptives, high rates of unintended pregnancies, and the pervasive HIV epidemic in Sub-Saharan Africa (SSA) poses a threat to maternal, newborn, and child health in the region. This study examined the prevalence, need, and demand satisfied by modern contraceptive methods for women who tested positive for HIV (both unmarried and married) in 10 countries in SSA. We used the Family Planning Estimation Too…

Many countri…
Assessment of the Trends and Factors Associated With Unintended Pregnancy Among Women of Reproductive Age
Background: Unintended pregnancy is a global public health issue with significant adverse effects which include health and economic consequences. Globally, there were 121 million unintended pregnancies annually between 2015 and 2019 among women of reproductive age between 15 and 49 mainly due to the non-uptake of modern contraceptives, harmful norms, stigma and lack of sexual and reproductive health care and information. Methods: We extracted inf…
Implementation of lockdown, quarantine, and isolation measures in the context of Covid-19 among internally displaced persons in Burkina Faso
Although there were no known cases of COVID-19 among the IDPs at the time of the study, tailored response plans were developed to facilitate the application of these measures in emergencies. The involvement of IDPs in the communication and sensitization process was necessary to facilitate their adherence to these different measures
Socioeconomic inequalities in uptake of HIV testing during antenatal care
We found that there is substantial wealth index-related inequalities in HIV testing, with women of the poorest wealth index disadvantaged in relation to the HIV testing. This emphasizes the necessity for sub-Saharan Africa public health programs to think about concentrating their limited resources on focused initiatives to grasp women from these socioeconomic circumstances. To increase women's access to HIV testing, maternal and child health prog…
Association between sexual violence and multiple high-risk fertility behaviours among women of reproductive age in sub-Saharan Africa

Maternal health care service utilization in post-war Liberia
The findings suggest that key maternal healthcare utilization indicators have improved substantially, especially facility-based delivery. However, a large proportion of women remain deprived of these life-saving health services in the post-war era. Greater healthcare efforts are needed to improve the quality and coverage of maternal healthcare in order to enhance maternal survival in Liberia
Decomposing the rural-urban gap in the factors of under-five mortality in sub-Saharan Africa? Evidence from 35 countries
These findings could be contributory to health care system improvement and socioeconomic developmental plans to address under-5 mortality in SSA. Strengthening maternal and child health (MCH) programmes, specifically in rural areas and improving health care services would help to ensure overall child survival
Association between intimate partner violence and utilization of facility delivery services in Nigeria
Women experiencing emotional violence are less likely to use institutional delivery services, and hence are susceptible to increased risk of reproductive complications. IPV is a complex issue that needs to be tackled by introducing evidence based strategies contextually relevant to local sociocultural environment. Further studies are required to understand the roots of IPV and the pathways through which it hindrances healthcare utilisation among …
Antenatal visits are positively associated with uptake of tetanus toxoid and intermittent preventive treatment in pregnancy in Ivory Coast
In this study, uptake of IPTp-SP drugs was much lower than TT immunization. High number of ANC visits were found to be significantly associated with taking IPTp-SP drugs and TT immunization and also with that of taking them in adequate doses. Vaccination promotion is necessary to protect pregnant women and reduce adverse health outcomes among the newborn in Ivory Coast
