Determinants of CD4 count recovery among severely immunosuppressed HIV patients initiated on antiretroviral therapy
Background For people living with HIV (PLWH), CD4 count serves as an effective indicator of response to antiretroviral therapy (ART) and a predictor of morbidity and mortality before and after ART initiation. In PLWH on ART, changes in CD4 count reflect immunological response to treatment. CD4 count recovery after ART initiation is defined as achieving a CD4 cell count of ≥500 cells/mm 3 . This study utilised survival analysis techniques to deter…
A geo-additive spatial analysis of condom use among women aged 15–49 in Rwanda
Background: Condom use in Rwanda is a significant public health topic, especially in efforts to prevent sexually transmitted infections (STIs), including HIV/AIDS, unplanned pregnancies and other health problems such as cervical cancer. In Rwanda, the government and various organizations actively promote condom use through comprehensive sexual and reproductive health initiatives such as sexual health education and condom distribution in schools, …
Syndemic mapping of HIV and other STIs in KwaZulu-Natal
Syndemics involving Human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) remain a major public health challenge in sub-Saharan Africa, and understanding their spatial and temporal dynamics is critical for effective interventions. Using data from two consecutive, population-based cross-sectional surveys conducted in 2014 and 2015 under the HIV Incidence Provincial Surveillance System (HIPSS) in KwaZulu-Natal, South A…
Investigating the Factors Influencing Traditional Male Circumcision and Its Contribution to HIV Transmission Amongst Men in Lesotho
The study highlights significant variation in TMC practices across communities and identifies both individual and contextual factors influencing its uptake. These insights underscore the need for culturally sensitive, voluntary, and medically safe circumcision programs. Public health initiatives should consider these determinants when designing interventions to ensure a safer and more effective implementation of TMC in Lesotho
Spatial Analysis of HIV Determinants Among Females Aged 15–34 in KwaZulu Natal, South Africa
HIV remains a major public health challenge in sub-Saharan Africa, with South Africa bearing the highest burden. This study confirms that KwaZulu-Natal (KZN) is a hotspot, with a high HIV prevalence of 47.4% (95% CI: 45.7-49.1) among females aged 15-34. We investigated the spatial distribution and key socio-demographic, behavioural, and economic factors associated with HIV prevalence in this group using a Bayesian spatial logistic regression mode…
A Bayesian Logistic Regression Approach to Investigating the Determinants Associated with Never Having Been Screened for Cervical Cancer Amongst Child-Bearing-Age Women in Jordan
Cervical cancer continues to be a major global public health problem, with 661,021 estimated new cases and 348,189 deaths reported in 2022. Approximately 53% of women in Jordan reported not being screened for CC in recent years. This study aimed to investigate the determinants associated with not being screened for CC amongst Jordanian women of child-bearing age. This was a cross-sectional study derived from the 2023 Jordanian Demographic Health …
A Multistate Continuous Time-Inhomogeneous Markov Model for Assessing the CD4 Count Dynamics of HIV/Aids Patients Undergoing Antiretroviral Therapy in KwaZulu-Natal, South Africa
Monitoring CD4 count levels is essential for tracking the progression of HIV in patients. This study aimed to identify the key factors influencing HIV progression by incorporating time-varying factors and transition probabilities. The data for this study were obtained from the Centre for the AIDS Programme of Research in South Africa (CAPRISA), which enrolled 3325 patients aged 14 to 76 who initiated antiretroviral therapy (ART) and were followed…
Prevalence and determinants of pregnancy termination for childbearing women using the modified Poisson regression model
The findings highlighted that the prevalence of terminating pregnancy is alarming in Tanzania, signaling a significant public health challenge. To address the concerning rates of pregnancy termination, the government of Tanzania and other institutions are advised to enhance the accessibility and quality of healthcare services for women, particularly in rural and underserved areas. Bridging socio-economic inequalities and removing geographic barri…
Estimating the risk of Sars-CoV-2 deaths using a Markov switching-volatility model combined with heavy-tailed distributions for South Africa
The MS(3)-GARCH(1,1)-PIVD model provides a reliable and accurate method for predicting the minimum number of death due to Covid-19. The accuracy of the proposed model will assist policymakers, academics and health practitioners in forecasting the volatility of future health-related deaths in which the predictability of volatility plays an integral role in health risk management
