Sexual and reproductive health and rights, HIV and migration in southern Africa: A rapid review

Migration, a prevalent global phenomenon, significantly impacts health, particularly in low- to middle-income countries. This article presents a rapid review aimed at mapping projects, lessons and policies concerning sexual and reproductive health (SRH), HIV and migration in southern Africa. Utilising a population-concept-context framework, the review focuses on understanding the scope, nature and extent of interventions, identifying lessons learnt, and assessing existing policies and strategies. A comprehensive search strategy and screening process resulted in 19 studies and reports for inclusion. The review highlighted diverse projects across southern Africa, addressing SRH and HIV among migrants, refugees and asylum seekers. Projects ranged from peer-education interventions to community-based referral systems, aiming to improve knowledge, access and outcomes related to SRH and HIV. The lessons learnt emphasised the importance of community involvement, healthcare worker (HCW) training and inclusive policies to address migrants’ diverse needs effectively. Additionally, projects facilitated cross-border collaborations and policy integration, enhancing access to SRH-HIV services and migrant health rights. Despite these efforts, challenges persist, including gender-based violence, financial barriers and xenophobic attitudes among HCWs. Limited access to comprehensive sexuality education and social protection for migrants underscores the need for further policy development and implementation. Nevertheless, existing policies, such as Botswana’s inclusive HIV treatment policy and South Africa’s National Strategic Plan for HIV, TB and STIs, demonstrate steps towards ensuring migrants’ rights to healthcare

Rural-urban disparities and socioeconomic determinants of caesarean delivery rates in Zimbabwe: Evidence from the 2019 National Multiple Indicator Cluster Survey

Caesarean sections (CSs) have increased globally, with concerns being raised involving overutilisation and inequalities in access. In Zimbabwe, where healthcare access varies greatly, we aimed to analyse factors associated with ever having a CS using the 2019 National Multiple Indicator Cluster Survey. The weighted national CS rate was 10.3%, and CS happened more commonly among women in urban than rural areas (15.7% v. 7.4%; odds ratio (OR) 2.34; (95% confidence interval (CI)) 1.71 - 3.20; p=0.001). Percentages of those having a CS significantly increased with education: overall χ2 for a trend of p=0.001 and wealth quintile, and overall χ2 for a trend of p=0.001. Women with insurance coverage were more likely to have had a CS than those without: 26.7% v. 8.7%; OR 3.82; 95% CI 2.51 - 5.83; p=0.001. The same was the case for women with access to the internet: 15.4% v. 7.0%, OR 2.42; 95%CI 1.71 - 3.41; p=0.001). These findings show an association that could indicate this being overutilised by insured women in urban settings, rather than being accessible based on clinical needs. Further research should explore reasons for these disparities and inform interventions to ensure equitable access to optimum childbirth in Zimbabwe

HIV status and contraceptive use in Zimbabwe among sexually active adolescent girls and women: Secondary analysis of Zimbabwe Demographic Health survey data

Background. Understanding the pattern of contraceptive use among women living with HIV is critical for formulating relevant public health interventions to improve the uptake and use of reliable methods in this population. This helps to reduce the incidence of unintended pregnancies. Objective. In this secondary data analysis, we aimed to describe contraceptive use by HIV-positive and HIV-negative sexually active adolescent girls and women, using data from the Zimbabwe Demographic and Health Survey (2015-16). Method. We used statistical analysis to determine the association between the use of various methods of contraception and HIV status using the Zimbabwe Demographic and Health Survey, 2015-16 data. Results. Overall, the contraceptive use prevalence in this study was 60%. Sexually active adolescent girls and women on the Pill and injections were less likely to be HIV-positive compared with those not using any method of contraception (odds ratio (OR)=0.54, 95% confidence interval (CI) (0.45 - 0.64), p=0.001; and OR=0.75, 95% CI (0.59 - 0.96), p=0.020, respectively). Those using either a male or female condom were more likely to be HIV-positive, OR=3.36, 95% CI (2.63 - 4.28), p=0.001. Conclusions. This study revealed that there is still a considerable unmet need for contraception among the study population, highlighting the need to devise strategies to increase contraception uptake among women. Statistically significant differences were noted in the use of condoms, with those who are HIV-positive having a higher use of condoms compared with those who are HIV-negative. This may reflect that HIV-positive individuals have received appropriate counselling messages on the need to use barrier methods

Using machine learning models to plan HIV services: Emerging opportunities in design, implementation and evaluation

HIV/AIDS remains one of the world’s most significant public health and economic challenges, with approximately 36 million people currently living with the disease. Considerable progress has been made to reduce the impact of HIV/AIDS in the past years through successful multiple HIV/AIDS prevention and treatment interventions. However, barriers such as lack of engagement, limited availability of early HIV-infection detection tools, high rates of HIV/sexually transmitted infections (STIs), barriers to access antiretroviral therapy, lack of innovative resource optimisation and distribution strategies, and poor prevention services for vulnerable populations still exist and substantially affect the attainment of the UNAIDS 95-95-95 targets. A rapid review was conducted from 24 October 2022 to 5 November 2022. Literature searches were conducted in different prominent and reputable electronic database repositories including PubMed, Google Scholar, Science Direct, Scopus, Web of Science, IEEE Xplore, and Springer. The study used various search keywords to search for relevant publications. From a list of collected publications, researchers used inclusion and exclusion criteria to screen and select relevant papers for inclusion in this review. This study unpacks emerging opportunities that can be explored by applying machine learning techniques to further knowledge and understanding about HIV service design, prediction, implementation, and evaluation. Therefore, there is a need to explore innovative and more effective analytic strategies including machine learning approaches to understand and improve HIV service design, planning, implementation, and evaluation to strengthen HIV/AIDS prevention, treatment, and awareness strategies

Social media for public health: Reaping the benefits, mitigating the harms

With more than 4.26 billion social media users worldwide, social media has become a primary source of health information, exchange, and influence. As its use has rapidly expanded, social media has proven to be a "doubled-edged sword," with considerable benefits as well as notable harms. It can be used to encourage preventive behaviors, foster social connectivity for better mental health, enable health officials to deliver timely information, and connect individuals to reliable information. But social media also has contributed to public health crises by exacerbating a decline in public trust, deteriorating mental health (especially in young people), and spreading dangerous misinformation. These realities have profound implications for health professionals, social media companies, governments, and users. We discuss promising guidelines, digital safety practices, and regulations on which to build a comprehensive approach to healthy use of social media. Concerted efforts from social media companies, governments, users, public interest groups, and academia are essential to mitigate the harms and unlock the benefits of this powerful new technology

Prevalence of nonsuppressed viral load and associated factors among HIV-positive adults receiving antiretroviral therapy in Eswatini, Lesotho, Malawi, Zambia and Zimbabwe (2015 to 2017): results from population-based nationally representative surveys.

INTRODUCTION The global target for 2020 is that ≥90% of people living with HIV (PLHIV) receiving antiretroviral therapy (ART) will achieve viral load suppression (VLS). We examined VLS and its determinants among adults receiving ART for at least four months. METHODS We analysed data from the population-based HIV impact assessment (PHIA) surveys in Eswatini, Lesotho, Malawi, Zambia and Zimbabwe (2015 to 2017). PHIA surveys are nationally representative, cross-sectional household surveys. Data collection included structured interviews, home-based HIV testing and laboratory testing. Blood samples from PLHIV were analysed for HIV RNA, CD4 counts and recent exposure to antiretroviral drugs (ARVs). We calculated representative estimates for the prevalence of VLS (viral load <1000 copies/mL), nonsuppressed viral load (NVL; viral load ≥1000 copies/mL), virologic failure (VF; ARVs present and viral load ≥1000 copies/mL), interrupted ART (ARVs absent and viral load ≥1000 copies/mL) and rates of switching to second-line ART (protease inhibitors present) among PLHIV aged 15 to 59 years who participated in the PHIA surveys in Eswatini, Lesotho, Malawi, Zambia and Zimbabwe, initiated ART at least four months before the survey and were receiving ART at the time of the survey (according to self-report or ARV testing). We calculated odds ratios and incidence rate ratios for factors associated with NVL, VF, interrupted ART, and switching to second-line ART. RESULTS We included 9200 adults receiving ART of whom 88.8% had VLS and 11.2% had NVL including 8.2% who experienced VF and 3.0% who interrupted ART. Younger age, male sex, less education, suboptimal adherence, receiving nevirapine, HIV non-disclosure, never having married and residing in Zimbabwe, Lesotho or Zambia were associated with higher odds of NVL. Among people with NVL, marriage, female sex, shorter ART duration, higher CD4 count and alcohol use were associated with lower odds for VF and higher odds for interrupted ART. Many people with VF (44.8%) had CD4 counts <200 cells/µL, but few (0.31% per year) switched to second-line ART. CONCLUSIONS Countries are approaching global VLS targets for adults. Treatment support, in particular for younger adults, and people with higher CD4 counts, and switching of people to protease inhibitor- or integrase inhibitor-based regimens may further reduce NVL prevalence
