RESUMO

OBJECTIVES: Despite declining TB notifications in Southern Africa, TB-related deaths remain high. We describe patient- and population-level trends in TB-related deaths in Eswatini over a period of 11 years. METHODS: Patient-level (retrospective cohort, from 2009 to 2019) and population-level (ecological analysis, 2009-2017) predictors and rates of TB-related deaths were analysed in HIV-negative and HIV-coinfected first-line TB treatment cases and the population of the Shiselweni region. Patient-level TB treatment data, and population and HIV prevalence estimates were combined to obtain stratified annual mortality rates. Multivariable Poisson regressions models were fitted to identify patient-level and population-level predictors of deaths. RESULTS: Of 11,883 TB treatment cases, 1302 (11.0%) patients died during treatment: 210/2798 (7.5%) HIV-negative patients, 984/8443 (11.7%) people living with HIV (PLHIV), and 108/642 (16.8%) patients with unknown HIV-status. The treatment case fatality ratio remained above 10% in most years. At patient-level, fatality risk was higher in PLHIV (aRR 1.74, 1.51-2.02), and for older age and extra-pulmonary TB irrespective of HIV-status. For PLHIV, fatality risk was higher for TB retreatment cases (aRR 1.38, 1.18-1.61) and patients without antiretroviral therapy (aRR 1.70, 1.47-1.97). It decreases with increasing higher CD4 strata and the programmatic availability of TB-LAM testing (aRR 0.65, 0.35-0.90). At population-level, mortality rates decreased 6.4-fold (-147/100,000 population) between 2009 (174/100,000) and 2017 (27/100,000), coinciding with a decline in TB treatment cases (2785 in 2009 to 497 in 2017). Although the absolute decline in mortality rates was most pronounced in PLHIV (-826/100,000 vs. HIV-negative: -23/100,000), the relative population-level mortality risk remained higher in PLHIV (aRR 4.68, 3.25-6.72) compared to the HIV-negative population. CONCLUSIONS: TB-related mortality rapidly decreased at population-level and most pronounced in PLHIV. However, case fatality among TB treatment cases remained high. Further strategies to reduce active TB disease and introduce improved TB therapies are warranted.

RESUMO

While oral pre-exposure prophylaxis (PrEP) can substantially reduce HIV risk, there are important barriers to uptake and adherence. We explored preferences for long-acting injectable and implantable PrEP among women and girls in Eswatini, Kenya, and South Africa. We conducted an online quantitative survey and discrete choice experiment (DCE) among adolescent girls (15-17), young women (18-29), and adult women (30-49). Participants completed a survey about their demographics and behavior and a DCE with 5 attributes (format, insertion location, number of insertions, dual-protection, and palpability). We recruited 1236 respondents (Eswatini = 420; Kenya = 350; South Africa = 493) in May 2022. Most participants were sexually active (72%), nearly 29% of whom reported recently engaging in transactional sex. 46% had heard of oral PrEP, but of those, only 16% reported having ever used it. Product format and dual-protection were significant predictors of product choice. Relative to a 2-month injection, participants had 1.76 times the odds (95% CI 1.08-2.04) of choosing a 6-month injectable, and 1.70 the odds (95% CI 1.06-1.92) of choosing a 12-month removable implant. Compared to a single-indication product, respondents had 2.46 times the odds (95% CI 1.04-2.68) of preferring a product also protecting against pregnancy, and 2.81 the odds (95% CI 1.04-3.05) of choosing a product that also protected against STIs. Adolescent girls and women in these countries showed strong preferences for longer-acting PrEP product formats, as well as those offering dual-protection. Introduction of long-acting options could improve PrEP uptake and reduce HIV burdens in east and southern African settings.

RESUMO

Studies continue to underscore the profound impact of sexual violence on women's health. Yet, little is known about the impact, via a complex matrix of behavioural and social factors, of first intercourse, namely forced non-consensual on HIV status, particularly among sexually active women (SAW) in low-income countries where HIV prevalence remains high. Using a national sample from Eswatini, we employed multivariate logistic regression modelling to estimate the associations between forced first-sex (FFS), subsequent sexual behaviour and HIV status among 3555 SAW aged from 15 years to 49 years. The results found that women who experienced FFS had a greater number of sexual partners compared to those who had never experienced FFS (aOR = 2.79, p < .01), although there were no significant differences in condom use, early sexual debut and casual sex involvement between these two groups. FFS remained significantly associated with a higher risk of having HIV (aOR = 1.70, p < .05) even after controlling for risky sexual behaviours and various other factors. These findings further reinforce the relationship between FFS and HIV, and suggest that addressing sexual violence is a critical component of HIV prevention among women in low-income countries.

RESUMO

Acute and early HIV infection (AEHI) is rarely diagnosed in sub-Saharan Africa, despite its potential contribution to incidence reduction. This qualitative study in Eswatini explored the experiences of health workers, people diagnosed with AEHI, and their partners towards AEHI diagnosis, to inform its scale-up. In-depth interviews were undertaken with 11 women and four men diagnosed with AEHI. Three patients' partners were interviewed about their understanding of AEHI and six health workers were interviewed about experiences of delivering AEHI services. Data were coded inductively and analysed iteratively following the principles of grounded theory. Experiences with AEHI diagnoses were shaped by (i) understanding the nature and consequences of AEHI, and (ii) social norms that influence disclosure and sexual behaviour. AEHI was a new concept for health workers who struggled to explain it to patients, leading to some confusion over their HIV status and misunderstandings around its high transmissibility and prognosis. Disclosure tended to occur to primary partners, if at all, limiting the ability to provide partner services, and one relationship breakdown was reported. If AEHI diagnosis and care interventions are to realise their full potential, it will be essential to reinforce the accompanying counselling sessions and closely monitor for potential social harms.

RESUMO

Men in Eswatini test for HIV at lower rates compared to women despite the widespread availability of HIV testing services in the country. HIV self-test kits have been proposed as an HIV testing model to reach more men by bypassing the health facility, which is known to be a barrier for men using HIV testing services. In this study, we sought to understand men's perspectives on HIV self-testing in Eswatini. We conducted semi-structured interviews with 22 men, recruited from a rural community and from an urban men's clinic, to assess their awareness of HIV self-testing and their perceptions of it as an alternative HIV testing option. Findings show that men were aware of HIV self-testing but had concerns that left most feeling hesitant about adopting it. Many men expressed doubts about the accuracy of self-testing and their own technical competence to use the kit without supervision. They also expressed fears about testing, and possibly learning they were HIV positive, without adequate pre - and post-HIV test counseling. To allay men's fears and improve uptake of HIV self-testing, practitioners might consider innovative methods such as virtual counseling services and linking HIV self-testing to other community-based HIV care services.

RESUMO

BACKGROUND: Tuberculosis (TB) is a major cause of mortality worldwide. Children and people living with HIV (PLHIV) have an increased risk of mortality, particularly in the absence of rapid diagnosis. The main challenges of diagnosing TB in these populations are due to the unspecific and paucibacillary disease presentation and the difficulty of obtaining respiratory samples. Thus, novel diagnostic strategies, based on non-respiratory specimens could improve clinical decision making and TB outcomes in high burden TB settings. We propose a multi-country, prospective diagnostic evaluation study with a nested longitudinal cohort evaluation to assess the performance of a new stool-based qPCR, developed by researchers at Baylor College of Medicine (Houston, Texas, USA) for TB bacteriological confirmation with promising results in pilot studies. METHODS: The study will take place in high TB/HIV burden countries (Mozambique, Eswatini and Uganda) where we will enroll, over a period of 30 months, 650 PLHIV (> 15) and 1295 children under 8 years of age (irrespective of HIV status) presenting pressumptive TB. At baseline, all participants will provide clinical history, complete a physical assessment, and undergo thoracic chest X-ray imaging. To obtain bacteriological confirmation, participants will provide respiratory samples (1 for adults, 2 in children) and 1 stool sample for Xpert Ultra MTB/RIF (Cepheid, Sunnyvale, CA, USA). Mycobacterium tuberculosis (M.tb) liquid culture will only be performed in respiratory samples and lateral flow lipoarabinomannan (LF-LAM) in urine following WHO recommendations. Participants will complete 2 months follow-up if they are not diagnosed with TB, and 6 months if they are. For analytical purposes, the participants in the pediatric cohort will be classified into "confirmed tuberculosis", "unconfirmed tuberculosis" and "unlikely tuberculosis". Participants of the adult cohort will be classified as "bacteriologically confirmed TB", "clinically diagnosed TB" or "not TB". We will assess accuracy of the novel qPCR test compared to bacteriological confirmation and Tb diagnosis irrespective of laboratory results. Longitudinal qPCR results will be analyzed to assess its use as treatment response monitoring. DISCUSSION: The proposed stool-based qPCR is an innovation because both the strategy of using a non-sputum based sample and a technique specially designed to detect M.tb DNA in stool.

RESUMO

BACKGROUND: This study evaluates the implementation and running costs of an HIV self-testing (HIVST) distribution program in Eswatini. HIVST kits were delivered through community-based and workplace models using primary and secondary distribution. Primary clients could self-test onsite or offsite. This study presents total running economic costs of kit distribution per model between April 2019 and March 2020, and estimates average cost per HIVST kit distributed, per client self-tested, per client self-tested reactive, per client confirmed positive, and per client initiating antiretroviral therapy (ART). METHODS: Distribution data and follow-up phone interviews were analysed to estimate implementation outcomes. Results were presented for each step of the care cascade using best-case and worst-case scenarios. A top-down incremental cost-analysis was conducted from the provider perspective using project expenditures. Sensitivity and scenario analyses explored effects of economic and epidemiological parameters on average costs. RESULTS: Nineteen thousand one hundred fifty-five HIVST kits were distributed to 13,031 individuals over a 12-month period, averaging 1.5 kits per recipient. 83% and 17% of kits were distributed via the community and workplace models, respectively. Clients reached via the workplace model were less likely to opt for onsite testing than clients in the community model (8% vs 29%). 6% of onsite workplace testers tested reactive compared to 2% of onsite community testers. Best-case scenario estimated 17,458 (91%) clients self-tested, 633 (4%) received reactive-test results, 606 (96%) linked to confirmatory testing, and 505 (83%) initiated ART. Personnel and HIVST kits represented 60% and 32% of total costs, respectively. Average costs were: per kit distributed US$17.23, per client tested US$18.91, per client with a reactive test US$521.54, per client confirmed positive US$550.83, and per client initiating ART US$708.60. Lower rates for testing, reactivity, and linkage to care in the worst-case scenario resulted in higher average costs along the treatment cascade. CONCLUSION: This study fills a significant evidence gap regarding costs of HIVST provision along the client care cascade in Eswatini. Workplace and community-based distribution of HIVST accompanied with effective linkage to care strategies can support countries to reach cascade objectives.

RESUMO

BACKGROUND: Improving treatment success rates among multi drug-resistant tuberculosis (MDR-TB) patients is critical to reducing its incidence and mortality, but adherence poses an important challenge. Video-based direct observed therapy (vDOT) may provide adherence benefits, while addressing the time and cost burden associated with community treatment supporter (CTS)-DOT. This study explored experiences of patients, family members and healthcare workers with different DOT modalities for adherence support in Eswatini. METHODS: Between April 2021 and May 2022, thirteen men and five women with MDR-TB, ten healthcare workers, and nine caregivers were purposively sampled to include a range of characteristics and experiences with DOT modalities. Data were generated through individual in-depth interviews and a smartphone messaging application (WhatsApp). Data coding was undertaken iteratively, and thematic analysis undertaken, supported by Nvivo. RESULTS: Four themes emerged that reflected participants' experiences with different DOT modalities, including stigma, efficiency, perceived risks of TB acquisition, and patient autonomy. vDOT was appreciated by patients for providing them with privacy and shielding them from stigmatisation associated with being seen in TB clinics or with community treatment supporters. vDOT was also seen as more efficient than CTS-DOT. Health workers acknowledged that it saved time, allowing them to attend to more patients, while many patients found vDOT more convenient and less expensive by removing the need to travel for in-person consultations. Health workers also appreciated vDOT because it reduced risks of TB acquisition by minimising exposure through virtual patient monitoring. Although many patients appreciated greater autonomy in managing their illness through vDOT, others preferred human contact or struggled with making video recordings. Most family members appreciated vDOT, although some resented feeling removed from the process of supporting loved ones. CONCLUSIONS: vDOT was generally appreciated by MDR-TB patients, their family members and health workers as it addressed barriers to adherence which could contribute to improved treatment completion rates and reduced workplace exposure. However, patients should be offered an alternative to vDOT such as CTS-DOT if this modality does not suit their circumstances or preferences.

RESUMO

BACKGROUND: Midwives encounter various difficulties while aiming to achieve excellence in providing maternity care to women with mobility disabilities. The study aimed to explore and describe midwives' experiences of caring for women with mobility disabilities during pregnancy, labour and puerperium in Eswatini. METHODS: A qualitative, exploratory, descriptive, contextual research design with a phenomenological approach was followed. Twelve midwives working in maternal health facilities in the Hhohho and Manzini regions in Eswatini were interviewed. Purposive sampling was used to select midwives to participate in the research. In-depth phenomenological interviews were conducted, and Giorgi's descriptive phenomenological method was used for data analysis. RESULTS: Three themes emerged from the data analysis: midwives experienced physical and emotional strain in providing maternity care to women with mobility disabilities, they experienced frustration due to the lack of equipment to meet the needs of women with mobility disabilities, and they faced challenges in providing support and holistic care to women with mobility disabilities during pregnancy, labour and puerperium. CONCLUSIONS: Midwives experienced challenges caring for women with mobility disabilities during pregnancy, labour and the puerperium in Eswatini. There is a need to develop and empower midwives with the knowledge and skill to implement guidelines and enact protocols. Moreover, equipment and infrastructure are required to facilitate support and holistic maternity care for women with mobility disabilities.

RESUMO

BACKGROUND: There is limited data on dolutegravir (DTG)-associated weight gain from settings with a dual burden of HIV and overnutrition. METHODS: In Eswatini (at Matsanjeni), among 156 and 160 adult patients on DTG-based and EFV-based antiretroviral therapy (ART), respectively, we studied excessive weight gain (BMI at 24 months ART greater than baseline and ≥25 kg/m2). RESULTS: The median BMI increase in DTG-based patients was 1.09 (IQR:-0.28,3.28) kg/m2 compared to 0.20 (IQR:-0.85,2.18) kg/m2 in EFV-based patients (p value = 0.001). DTG-based ART predicted excessive weight gain (aOR 2.61;95% CI:1.39-4.93). CONCLUSION: Practitioners should consider DTG-based regimens as one of the risk factors for overweight/obesity.

RESUMO

BACKGROUND: Video-enabled directly observed therapy (video-DOT) has been proposed as an additional option for treatment provision besides in-person DOT for patients with drug-resistant TB (DRTB) disease. However, evidence and implementation experience mainly originate from well-resourced contexts. This study describes the operationalization of video-DOT in a low-resourced setting in Eswatini facing a high burden of HIV and TB amid the emergence of the COVID-19 pandemic. METHODS: This is a retrospectively established cohort of patients receiving DRTB treatment during the implementation of video-DOT in Shiselweni from May 2020 to March 2022. We described intervention uptake (vs. in-person DOT) and assessed unfavorable DRTB treatment outcome (death, loss to care) using Kaplan-Meier statistics and multivariable Cox-regression models. Video-related statistics were described with frequencies and medians. We calculated the fraction of expected doses observed (FEDO) under video-DOT and assessed associations with missed video uploads using multivariable Poisson regression analysis. RESULTS: Of 71 DRTB patients eligible for video-DOT, the median age was 39 (IQR 30-54) years, 31.0% (n = 22) were women, 67.1% (n = 47/70) were HIV-positive, and 42.3% (n = 30) were already receiving DRTB treatment when video-DOT became available. About half of the patients (n = 37; 52.1%) chose video-DOT, mostly during the time when COVID-19 appeared in Eswatini. Video-DOT initiations were lower in new DRTB patients (aHR 0.24, 95% CI 0.12-0.48) and those aged ≥ 60 years (aHR 0.27, 95% CI 0.08-0.89). Overall, 20,634 videos were uploaded with a median number of 553 (IQR 309-748) videos per patient and a median FEDO of 92% (IQR 84-97%). Patients aged ≥ 60 years were less likely to miss video uploads (aIRR 0.07, 95% CI 0.01-0.51). The cumulative Kaplan-Meier estimate of an unfavorable treatment outcome among all patients was 0.08 (95% CI 0.03-0.19), with no differences detected by DOT approach and other baseline factors in multivariable analysis. CONCLUSIONS: Implementing video-DOT for monitoring of DRTB care provision amid the intersection of the HIV and COVID-19 pandemics seemed feasible. Digital health technologies provide additional options for patients to choose their preferred way to support treatment taking, thus possibly increasing patient-centered health care while sustaining favorable treatment outcomes.

RESUMO

Fertility rates remain high in certain subgroups of the population, and there is limited research about the sociodemographic factors influencing fertility, particularly in Eswatini where women are often considered minors. This study aims to investigate the changes in lifetime fertility, and the associations between sociodemographic factors and lifetime fertility among ever-married women. The study used secondary cross-sectional data from the 2010 and 2014 Eswatini Multiple Indicator Cluster Surveys (MICS), with a sample size of 2,295 and 2,351 women, respectively. The data was analysed using descriptive statistics and multivariable Poisson regression. The results showed that fertility rates decreased from 3.47 to 3.21 children between 2010 and 2014. The study found that child loss and age (25+ years) were significant factors associated with higher fertility, while delayed age at marriage and sexual debut (20+ years), at least secondary education, and being rich were strong predictors of lower fertility rates. The study recommends creating awareness about and strengthening laws to abolish early sexual debut and marriage. It also suggests empowering women through education, encouraging the use of contraceptives, and providing maternal and child health services in rural areas where fertility rates tend to be higher.


Les taux de fécondité restent élevés dans certains sous-groupes de la population, et les recherches sur les facteurs sociodémographiques influençant la fécondité sont limitées, en particulier à Eswatini où les femmes sont souvent considérées comme mineures. Cette étude vise à étudier les changements dans la fécondité au cours de la vie et les associations entre les facteurs sociodémographiques et la fécondité au cours de la vie chez les femmes déjà mariées. L'étude a utilisé des données transversales secondaires des enquêtes par grappes à indicateurs multiples (MICS) d'Eswatini de 2010 et 2014, avec un échantillon de 2 295 et 2 351 femmes, respectivement. Les données ont été analysées à l'aide de statistiques descriptives et d'une régression de Poisson multivariée. Les résultats ont montré que les taux de fécondité ont diminué de 3,47 à 3,21 enfants entre 2010 et 2014. L'étude a révélé que la perte d'enfants et l'âge (25 ans et plus) étaient des facteurs importants associés à une fécondité plus élevée, tandis qu'un âge plus tardif au mariage et aux débuts sexuels (20 ans et plus) ), au moins une éducation secondaire, et le fait d'être riche étaient de puissants prédicteurs de taux de fécondité plus faibles. L'étude recommande de sensibiliser et de renforcer les lois visant à abolir les premiers rapports sexuels et le mariage précoces. Il suggère également d'autonomiser les femmes grâce à l'éducation, d'encourager l'utilisation de contraceptifs et de fournir des services de santé maternelle et infantile dans les zones rurales où les taux de fécondité ont tendance à être plus élevés.

RESUMO

Mediation analysis is widely used in biomedical research to quantify the extent to which the effect from an exposure on a health outcome is through a mediator and the extent to which the effect is direct. A traditional approach for quantifying mediation is through the difference method. The other popular approach uses a counterfactual framework from which the product method arises. However, there is little prior work to articulate which method is more efficient for estimating 2 key quantities in mediation analysis, the natural indirect effect and mediation proportion. To fill in this gap, we investigated the asymptotic relative efficiency for mediation measure estimators given by the product method and the difference method. We considered 4 data types characterized by continuous and binary mediators and outcomes. Under certain conditions, we show analytically that the product method is equally efficient to the difference method, or more efficient. However, our numerical studies demonstrate that the difference method is usually at least 90% as efficient as the product method under realistic scenarios in epidemiologic research, especially for estimating the mediation proportion. We demonstrate the efficiency results by analyzing the MaxART study (Eswatini, 2014-2017), which aimed to evaluate the effectiveness of the early access to antiretroviral therapy among human immunodeficiency virus-positive patients.

RESUMO

User costs constitute a barrier to the uptake of HIV pre-exposure prophylaxis (PrEP), but their magnitude appears rarely assessed. In this prospective observational study, we assessed self-reported out-of-pocket expenses (OOPE) and time spent on clinic visits during a PrEP demonstration project in Eswatini. At six public primary care clinics, 240 PrEP users and other clinic attendees were interviewed after a clinic visit. Among the 79.2% of clinic attendees reporting any medical OOPE (e.g., expenses for consultations or drugs) and/or non-medical OOPE (e.g., expenses for transport, food, or phone use), the median total OOPE was $1.36 (IQR 0.91-1.96). Non-medical OOPE occurred mostly due to transport expenses. The median travel time for a clinic visit was 1.0 h (IQR 0.67-2.0). The median time spent in the clinic was 2.0 h (IQR 1.15-3.0). The median opportunity cost of a clinic visit was $7.54 (IQR 5.42-11) when valuing time spent on a clinic visit with Eswatini's per-capita gross domestic product. Our findings can guide measures to reduce the user costs of PrEP in Eswatini and other contexts in which oral PrEP is provided through health care facilities.


RESUMEN: Los costes de los usuarios constituyen un obstáculo para la adopción de la profilaxis previa a la exposición al VIH (PrEP), pero su magnitud rara vez se evalúa. En este estudio observacional prospectivo, evaluamos los gastos de bolsillo (OOPE) declarados por los propios usuarios y el tiempo dedicado a las visitas clínicas durante un proyecto de demostración de la PrEP en Eswatini. En seis clínicas públicas de atención primaria, se entrevistó a 240 usuarios de la PrEP y a otros asistentes a la clínica después de una visita a la misma. Entre el 79,2% de los asistentes a las clínicas que declararon algún OOPE médico (por ejemplo, gastos por consultas o medicamentos) y/o OOPE no médico (por ejemplo, gastos de transporte, comida o uso del teléfono), la mediana del OOPE total fue de 1,36 dólares (IQR: 0,91­1,96). Los gastos no médicos se debieron principalmente a los gastos de transporte. La mediana del tiempo de viaje para una visita a la clínica fue de 1,0 horas (IQR 0,67­2,0). La mediana del tiempo empleado en la clínica fue de 2 horas (IQR 1,15­3,0). La mediana del coste de oportunidad de una visita a la clínica fue de 7,65 dólares (IQR 5,55­11) al valorar el tiempo dedicado a una visita a la clínica con el producto interior bruto per cápita de Eswatini. Nuestros resultados pueden orientar las medidas para reducir los costes de uso de la PrEP en Eswatini y en otros contextos en los que se suministra la PrEP oral a través de los centros de salud.

RESUMO

Eswatini has a high HIV prevalence but has made progress towards improving HIV-status awareness, ART uptake and viral suppression. However, there is still a delay in ART initiation, which could partly be attributed to positive HIV-retesting. This study examines reasons for, and factors associated with, positive HIV-retesting among MaxART participants in Eswatini. Data from 601 participants is included in this cross-sectional study. Descriptive statistics and logistic regressions were used. Of the participants, 32.8% has ever retested after a previous positive result. Most participants who retested did this because they could not accept their results (61.9% of all retesters). Other main reasons are related to external influences, gender or the progression of their HIV infection (respectively 18.3%, 10.2%, and 6.1% of all retesters). Participants without a current partner and participants with less time since their first positive test have lower odds of retesting. To decrease retesting and reduce the delay in ART initiation resulting from it, efforts could be made on increasing the acceptance of positive HIV results. Providing more information on the process of testing and importance of early ART initiation, could be part of the solution.

RESUMO

This study investigated the relationship between gender, working status, and access to HIV care and explored whether working status mediates the relationship between gender and access to HIV care. Nationally representative data from the 2016 Swaziland HIV Incidence Measurement Survey used. Sample comprised of 2,826 adults positive for HIV. Both 30-day and 1-year employment records were used to define working status. Access to HIV care was defined using data on both HIV viral load suppression and current antiretroviral therapy (ART) enrollment. People who worked in the past 12 months had a significantly lower likelihood of current ART enrollment (odds ratio [OR] 0.75; 95% confidence interval [CI]: 0.62-0.91) and viral load suppression (OR 0.78; 95% CI: 0.67-0.92). Working in the past 30 days was also significantly associated with current ART enrollment (OR 0.71; 95% CI: 0.59-0.85) and viral load suppression (OR 0.78; 95% CI: 0.66-0.93). The negative influence of working status on access to HIV care (current ART enrollment and viral load suppression) was stronger in men than in women. Working status partially explained the relationship between gender (male) and access to HIV care. Time constraints are a likely explanation for this.

RESUMO

BACKGROUND: The tuberculosis (TB) epidemic remains a major global health problem and Eswatini is not excluded. Our study investigated the circulating genotypes in Eswatini and compared them at baseline (start of treatment) and follow-up during TB treatment. METHODS: Three hundred and ninety (n = 390) participants were prospectively enrolled from referral clinics and patients who met the inclusion criteria, were included in the study. A total of 103 participants provided specimens at baseline and follow-up within six months. Mycobacterium tuberculosis (M.tb) strains were detected by GeneXpert® MTB/RIF assay (Cephied, USA) and Ziehl -Neelsen (ZN) microscopy respectively at baseline and follow-up time-points respectively. The 206 collected specimens were decontaminated and cultured on BACTEC™ MGIT™ 960 Mycobacteria Culture System (Becton Dickinson, USA). Drug sensitivity testing was performed at both baseline and follow-up time points. Spoligotyping was performed on both baseline and follow-up strains after DNA extraction. RESULTS: Resistance to at least one first line drug was detected higher at baseline compared to follow-up specimens with most of them developing into multidrug-resistant (MDR)-TB. A total of four lineages and twenty genotypes were detected. The distribution of the lineages varied among the different regions in Eswatini. The Euro-American lineage was the most prevalent with 46.12% (95/206) followed by the East Asian with 24.27% (50/206); Indo-Oceanic at 9.71% (20/206) and Central Asian at 1.94% (4/206). Furthermore, a high proportion of the Beijing genotype at 24.27% (50/206) and S genotype at 16.50% (34/206) were detected. The Beijing genotype was predominant in follow-up specimens collected from the Manzini region with 48.9% (23/47) (p = 0.001). A significant proportion of follow-up specimens developed MDR-TB (p = 0.001) with Beijing being the major genotype in most follow-up specimens (p < 0.000). CONCLUSION: Eswatini has a high M.tb genotypic diversity. A significant proportion of the TB infected participants had the Beijing genotype associated with MDR-TB in follow-up specimens and thus indicate community wide transmission.

RESUMO

BACKGROUND: In countries such as Eswatini, where there is a high HIV prevalence and low male circumcision the World Health Organization and the Joint United Nations Programme for HIV/AIDS recommend infant and adult circumcision be implemented. The aim of this study was to assess the knowledge, attitudes and acceptability of voluntary medical male circumcision amongst males attending high school in Eswatini. METHODS: An observational cross-sectional study was conducted during February and March of 2018 amongst 407 young males (15-21 years) attending Form 4, in nine high schools in the Shiselweni region of Eswatini using a self-administered questionnaire of 42 close ended questions. Sociodemographic details, circumcision status, acceptance of voluntary medical male circumcision, knowledge and attitude scores analysed in Stata® 14 statistical software were described using frequencies, medians and ranges respectively. Bivariate and multivariate linear regression was used to assess the impact of independent variables on circumcision status and acceptance of voluntary medical male circumcision. The level of statistical significance was p < 0.05. RESULTS: Amongst the 407 high school-going males, 48.98% (n = 201) reported being circumcised. The majority of the adolescents (75.74%; n = 306) were knowledgeable about voluntary medical male circumcision. However, an even larger majority (84.90% (n = 343) had a negative attitude towards it. In the multivariate logistic regression analysis, having parented their own children (aOR: 3.55; 95%CI: 1.2-10.48), and having circumcised friends (aOR: 3.99; 95%CI: 1.81-8.84) were significantly associated with being circumcised. Neither knowledge nor attitude were associated with the acceptability of voluntary medical male circumcision. CONCLUSION: In Eswatini male high school students are knowledgeable about voluntary medical male circumcision but have a negative attitude towards it. Having parented their own children, and having circumcised friends influenced being circumcised.

RESUMO

BACKGROUND: In 2018, Eswatini had the world's highest age-standardised cervical cancer incidence rate. Cervical cancer screening reduces women's risk of invasive cervical cancer. Data on adherence to cervical cancer screening recommendations in Eswatini are scarce. The purpose of the current study was to determine Eswatini women's self-reported adherence to cervical cancer screening recommendations, attitudes toward screening, and factors associated with non-adherence. METHODS: A cross-sectional survey of women (n = 377) aged 25 to 59 accessing primary healthcare clinics (n = 4) in Eswatini assessed screening participation, attitudes and knowledge regarding cervical cancer screening, and socio-demographic variables. Adjusted logistic regression was used to assess factors associated with non-adherence to Eswatini cervical cancer screening recommendations. RESULTS: One hundred and sixty-six (44%) women were classified as adherent to cervical cancer screening recommendations. Attitudinal barriers endorsed by over one-third of participants included a perceived low risk of cervical cancer (n = 161, 43%) and a view that screening is likely to be painful (n = 146, 38%). Participants had higher odds of being classified as non-adherent if they: were single compared with married (OR = 1.78, 95% CI: 1.05, 3.01, p = 0.03), perceived screening as likely painful (OR = 4.43, 95% CI: 2.62, 7.46, p < 0.001); and had not been advised by a doctor/ nurse to screen (OR = 2.82, 95% CI: 1.71, 4.64, p < 0.001). Also, a 1-year increase in age was associated with an increase in the odds of being classified as non-adherent (OR = 1.42, 95% CI: 1.39, 1.45, p = 0.01). CONCLUSIONS: Self-reported adherence was moderate among this group of women. Tailored interventions are needed to increase participation in cervical cancer screening, especially for those women with characteristics associated with being classified as non-adherent. Primary healthcare clinic nurses (and other health providers) may contribute toward improving participation in cervical cancer screening by advising eligible women to screen and providing health education addressing negative attitudes toward screening.

RESUMO

BACKGROUND: Cervical cancer stands as one of the most prevalent cancer types among women, despite its preventable nature through early screening and vaccination strategies. The link between being overweight or obese and various adverse health outcomes, including an elevated cancer risk, is well established. Within this study, our central objective was to explore the correlation between body mass index (BMI) and cervical cancer screening (CCS) rates. Moreover, we sought to investigate whether socioeconomic status potentially modulates this relationship. METHODS: Our analysis encompassed 1791 respondents who participated in the World Health Organization's STEPwise approach to noncommunicable disease risk factor surveillance carried out in Eswatini in 2014. We assessed the connection between BMI, along with other determinants, and CCS through both unadjusted and adjusted logistic regression models. RESULTS: The uptake of CCS was 14.4% and the prevalence of overweight and obesity was estimated at 28.1 and 34.9% respectively. After accounting for other pertinent variables, the likelihood of obtaining CCS was amplified for individuals classified as obese (adjusted odds ratio [aOR] = 1.99, 95% confidence interval [CI] = 1.26-3.12) or overweight (aOR = 1.98, 95% CI = 1.05-3.74). Furthermore, factors such as being separated or divorced (aOR = 2.03, 95% CI = 1.11-3.72) and engaging in regular physical exercise (aOR = 3.02, 95% CI = 1.21-6.02) were associated with increased odds of undergoing CCS. CONCLUSIONS: This study underscores the noteworthy role played by both overweight and obesity, in conjunction with various socioeconomic factors, in shaping CCS patterns among the surveyed women. For Eswatini, targeted interventions aimed at enhancing CCS participation should take into account the multifaceted factors highlighted within this investigation.
