RESUMO

BACKGROUND: Chronic lung disease (CLD) is common among children with HIV (CWH) including in those taking antiretroviral therapy (ART). Azithromycin has both antimicrobial and anti-inflammatory effects and has been effective in improving lung function in a variety of lung diseases. We investigated lung function trajectories among CWH with CLD on ART enrolled in a randomized controlled trial of adjuvant azithromycin. We also investigated factors that modified the effect of azithromycin on lung function. METHODS: The study used data from a double-blinded placebo-controlled trial conducted in Malawi and Zimbabwe of 48 weeks on azithromycin (BREATHE: ClinicalTrials.gov NCT02426112) among CWH aged 6 to 19 years taking ART for at least six months who had a forced expiratory volume in one second (FEV1) z-score <-1.0. Participants had a further follow-up period of 24 weeks after intervention cessation. FEV1, forced vital capacity (FVC) and FEV1/FVC were measured at baseline, 24, 48 and 72-weeks and z-scores values calculated. Generalized estimating equations (GEE) models were used to determine the mean effect of azithromycin on lung-function z-scores at each follow-up time point. RESULTS: Overall, 347 adolescents (51% male, median age 15 years) were randomized to azithromycin or placebo. The median duration on ART was 6.2 (interquartile range: 3.8-8.6) years and 56.2% had an HIV viral load < 1000copies/ml at baseline. At baseline, the mean FEV1 z-score was - 2.0 (0.7) with 44.7% (n = 155) having an FEV1 z-score <-2, and 10.1% had microbiological evidence of azithromycin resistance. In both trial arms, FEV1 and FVC z-scores improved by 24 weeks but appeared to decline thereafter. The adjusted overall mean difference in FEV1 z-score between the azithromycin and placebo arms was 0.004 [-0.08, 0.09] suggesting no azithromycin effect and this was similar for other lung function parameters. There was no evidence of interaction between azithromycin effect and baseline age, lung function, azithromycin resistance or HIV viral load. CONCLUSION: There was no observed azithromycin effect on lung function z-scores at any time point suggesting no therapeutic effect on lung function.

RESUMO

OBJECTIVES: Hazardous drinking (HD) and substance use (SU) can lead to disinhibited behaviour and are both growing public health problems among Southern African youths. We investigated the prevalence of SU and HD and their association with risky sexual behaviour among youth in Zimbabwe. DESIGN: Data analysis from a population-based survey conducted between October 2021 and June 2022 to ascertain the outcomes of a cluster randomised trial (CHIEDZA: Trial registration number:NCT03719521). Trial Stage: Post-results. SETTING: 24 communities in three provinces in Zimbabwe. PARTICIPANTS: Youth aged 18-24 years living in randomly selected households. OUTCOME MEASURES: HD was defined as an Alcohol Use Disorders Identification Test score ≥8, SU was defined as ever use of ≥1 commonly used substances in the local setting. RESULTS: Of 17 585 participants eligible for this analysis, 61% were women and the median age was 20 (IQR: 19-22) years. Overall, 4.5% and 7.0% of participants reported HD and SU, respectively. Men had a substantially higher prevalence than women of HD (8.2% vs 1.9%) and SU (15.1% vs 1.5%). Among men, after adjusting for socio-demographic factors, we found increased odds of having >1 sexual partner in those who engaged in SU (adjusted OR (aOR)=2.67, 95% CI: 2.21 to 3.22), HD (aOR=3.40, 95% CI: 2.71 to 4.26) and concurrent HD and SU (aOR=4.57,95% CI: 3.59 to 5.81) compared with those who did not engage in HD or SU. Similarly, there were increased odds of receiving/providing transactional sex among men who engaged in SU (aOR=2.51, 95% CI: 1.68 to 3.74), HD (aOR=3.60, 95% CI: 2.24 to 5.79), and concurrent HD and SU (aOR=7.74, 95% CI: 5.44 to 11.0). SU was associated with 22% increased odds of inconsistent condom use in men (aOR=1.22, 95% CI: 1.03 to 1.47). In women, the odds of having >1 sexual partner and having transactional sex were also increased among those who engaged in SU and HD. CONCLUSION: SU and HD are associated with sexual behaviours that increase the risk of HIV acquisition in youth. Sexual and reproductive health interventions must consider HD and SU as potential drivers of risky sexual behaviour in youths.

RESUMO

OBJECTIVES: Youth are at high risk of sexually transmitted infections (STIs) in Africa. We aimed to determine the risk factors for curable STIs in youth in Zimbabwe. METHODS: A population-based survey was conducted among randomly selected 18-24 year-olds in 16 communities across two provinces in Zimbabwe to ascertain outcomes for a cluster randomised trial investigating the impact of community-based STI screening for youth on population prevalence of STIs. Participants underwent an interviewer-administered questionnaire, HIV testing and screening for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV). Risk factors for curable STIs were explored through multivariable logistic regression. RESULTS: Of the 5601 participants, 62.5% (n=3500) were female, and the median age was 20 (IQR 19-22) years. HIV prevalence was 6.3% (351/5556), and 55.4% (1939/3501) reported condomless sex at last intercourse. Only 7.2% (401/5599) reported STI symptoms, but CT/NG/TV prevalence was 19.8% (1107/5601). On multivariable analysis, factors associated with STI diagnosis included being aged 21-24 years (adjusted OR (aOR) 1.37, 95% CI 1.17 to 1.61); female sex (aOR 2.11, 95% CI 1.76 to 2.53); being unemployed/informally employed (compared with in education/formal employment) (aOR 1.35, 95% CI 1.13 to 1.61); increasing number of sexual partners in the preceding 12 months (one partner: aOR 2.23, 95% CI 1.73 to 2.88; two partners: aOR 2.39, 95% CI 1.69 to 3.39); living with HIV (aOR 1.44, 95% CI 1.07 to 1.94); and previous attempted suicide (aOR 1.58, 95% CI 1.08 to 2.32). CONCLUSIONS: The prevalence of STIs among youth in Zimbabwe is high, particularly among those with HIV. In addition to moving away from syndromic STI management and strengthening implementation of existing prevention tools, there is a need for a more holistic focus on broader risk factors such as mental health and employment opportunities, and of integration of HIV and STI programming. TRIAL REGISTRATION NUMBER: ISRCTN15013425, NCT03719521.

RESUMO

BACKGROUND: Despite being integral to women's well-being, achieving good menstrual health (MH) remains a challenge. This study examined MH services uptake (including information, analgesics, and a choice of MH products - the menstrual cup and reusable pads) and sustained use of MH products within an integrated sexual and reproductive health intervention for young people in Zimbabwe. METHODS: This mixed-methods study was nested within a cluster randomised trial of integrated sexual and reproductive health services (CHIEDZA) for youth in three provinces (Harare, Mashonaland East, and Bulawayo). The study collected qualitative and quantitative data from 27,725 female clients aged 16-24 years, who accessed CHIEDZA from April 2019 - March 2022. Using a biometric (fingerprint recognition) identification system, known as SIMPRINTS, uptake of MH information, products, and analgesics and other services was tracked for each client. Descriptive statistics and logistic regression were used to investigate MH service uptake and product choice and use over time, and the factors associated with these outcomes. Thematic analysis of focus group discussions and interviews were used to further explore providers' and participants' experiences of the MH service and CHIEDZA intervention. RESULTS: Overall, 36,991 clients accessed CHIEDZA of whom 27,725 (75%) were female. Almost all (n = 26,448; 95.4%) took up the MH service at least once: 25433 took up an MH product with the majority (23,346; 92.8%) choosing reusable pads. The uptake of cups varied across province with Bulawayo province having the highest uptake (13.4%). Clients aged 20-24 years old were more likely to choose cups than reusable pads compared with those aged 16-19 years (9.4% vs 6.0%; p < 0.001). Over the implementation period, 300/1819 (16.5%) of clients swapped from the menstrual cup to reusable pads and 83/23346 (0.4%) swapped from reusable pads to the menstrual cup. Provision of the MH service encouraged uptake of other important SRH services. Qualitative findings highlighted the provision of free integrated SRH and MH services that included a choice of MH products and analgesics in a youth-friendly environment were key to high uptake and overall female engagement with SRH services. CONCLUSIONS: High uptake demonstrates how the MH service provided much needed access to MH products and information. Integration of MH within an SRH intervention proved central to young women accessing other SRH services.

RESUMO

Youth living with HIV are at higher risk than adults of disengaging from HIV care. Differentiated models of care such as community delivery of antiretroviral therapy (ART) may improve treatment outcomes. We investigated outcomes across the HIV cascade among youth accessing HIV services in a community-based setting. This study was nested in a cluster-randomised controlled trial (CHIEDZA: Clinicaltrials.gov, Registration Number: NCT03719521) conducted in three provinces in Zimbabwe and aimed to investigate the impact of a youth-friendly community-based package of HIV services, integrated with sexual and reproductive health services for youth (16-24 years), on population-level HIV viral load (VL). HIV services included HIV testing, ART initiation and continuous care, VL testing, and adherence support. Overall 377 clients were newly diagnosed with HIV at CHIEDZA, and linkage to HIV care was confirmed for 265 (70.7%, 234 accessed care at CHIEDZA and 31 with other providers); of these 250 (94.3%) started ART. Among those starting ART at CHIEDZA who did not transfer out and had enough follow up time (>6 months), 38% (68/177) were lost-to-follow-up within six months. Viral suppression (HIV Viral Load <1000 copies/ml) among those who had a test at 6 months was 90% (96/107). In addition 1162 clients previously diagnosed with HIV accessed CHIEDZA; 714 (61.4%) had a VL test, of whom 565 (79.1%) were virally suppressed. This study shows that provision of differentiated services for youth in the community is feasible. Linkage to care and retention during the initial months of ART was the main challenge and needs concerted attention to achieve the ambitious 95-95-95 UNAIDS targets.

RESUMO

Health workers are essential for a functioning healthcare system, and their own health is often not addressed. During the COVID-19 pandemic health workers were at high risk of SARS-CoV-2 infection whilst coping with increased healthcare demand. Here we report the development, implementation, and uptake of an integrated health check combining SARS-CoV-2 testing with screening for other communicable and non-communicable diseases for health workers in Zimbabwe during the COVID-19 pandemic. Health checks were offered to health workers in public and private health facilities from July 2020 to June 2022. Data on the number of health workers accessing the service and yield of screening was collected. Workshops and in-depth interviews were conducted to explore the perceptions and experiences of clients and service providers. 6598 health workers across 48 health facilities accessed the service. Among those reached, 5215 (79%) were women, the median age was 37 (IQR: 29-44) years and the largest proportion were nurses (n = 2092, 32%). 149 (2.3%) healthcare workers tested positive for SARS-CoV-2. Uptake of screening services was almost 100% for all screened conditions except HIV. The most common conditions detected through screening were elevated blood pressure (n = 1249; 19%), elevated HbA1c (n = 428; 7.7%) and common mental disorder (n = 645; 9.8%). Process evaluation showed high acceptability of the service. Key enablers for health workers accessing the service included free and comprehensive service provision, and availability of reliable point-of-care screening methods. Implementation of a comprehensive health check for health workers was feasible, acceptable, and effective, even during a pandemic. Conventional occupational health programmes focus on infectious diseases. In a society where even health workers cannot afford health care, free comprehensive occupational health services may address unmet needs in prevention, diagnosis, and treatment for chronic non-communicable conditions.

RESUMO

The burden of non-communicable diseases (NCDs) in southern Africa is expanding and is superimposed on high HIV prevalence. Healthcare workers are a scarce resource; yet are vital to health systems. There are very limited studies on the burden of chronic conditions among healthcare workers in Africa, and none exploring multimorbidity (≥2 chronic conditions). We describe the epidemiology of infectious (HIV) and non-communicable chronic conditions, and multimorbidity, among Zimbabwean healthcare workers. Healthcare workers (≥18 years) in eight Zimbabwean provinces were invited to a voluntary, cross-sectional health-check, including HIV, diabetes, hypertension and mental health screening. Statistical analyses described the prevalence and risk factors for multimorbidity (two or more of HIV, diabetes, hypertension or common mental disorder) and each condition. Missing data were handled using multiple imputation. Among 6598 healthcare workers (July 2020-July 2022) participating in the health-check, median age was 37 years (interquartile range 29-44), 79% were women and 10% knew they were living with HIV. Half had at least one chronic condition: 11% were living with HIV, 36% had elevated blood pressure, 12% had elevated HbA1c and 11% had symptoms of common mental disorder. The overall prevalence of multimorbidity was 15% (95% CI: 13-17%); 39% (95% CI: 36-43%) among people aged 50 and older. Whilst most HIV was diagnosed and treated, other chronic conditions were usually undiagnosed or uncontrolled. Limiting our definition of multimorbidity to two or more screened conditions sought to reduce bias due to access to diagnosis, however, may have led to a lower reported prevalence than that found using a wider definition. Half of healthcare workers screened were living with a chronic condition; one in seven had multimorbidity. Other than HIV, most conditions were undiagnosed or untreated. Multisectoral action to implement contextually relevant, chronic disease services in Africa is urgently needed. Specific attention on health workers is required to protect and retain this critical workforce.

RESUMO

BACKGROUND: Hypertension is the greatest driver of cardiovascular mortality and onset might be in youth. We aimed to investigate the prevalence of and risk factors for elevated blood pressure (hypertension ≥140 mm Hg systolic, ≥90 mm Hg diastolic, or both) and high-normal blood pressure (130-139 mm Hg systolic, 85-89 mm Hg diastolic, or both) among youth in Zimbabwe. METHODS: A population-based, cross-sectional survey of randomly sampled youth aged 18-24 years from 24 urban and peri-urban communities in three provinces (Harare, Bulawayo, and Mashonaland East) in Zimbabwe was conducted between Oct 4, 2021, and June 2, 2022. Standardised questionnaires were used by research assistants to collect sociodemographic, behavioural, and clinical data. Height, bodyweight, and blood pressure were recorded. Three seated blood pressure measurements were taken at standardised timepoints during participant interview using a digital sphygmomanometer and cuffs sized on mid-upper arm circumference. The association of potential risk factors with elevated blood pressure was examined using multivariable logistic regression. FINDINGS: 17 682 (94·4%) of 18 729 eligible participants were recruited, 17 637 (99·7%) of whom had complete data, and 16 883 (95·7%) of whom were included in the final study sample after excluding 754 (4·3%) pregnant women. The median age was 20 years (IQR 19-22), 9973 (59·1%) participants were female, and 6910 (40·9%) were male. The prevalence of hypertension was 7·4% (95% CI 7·0-7·8) and high-normal blood pressure was 12·2% (11·7-12·7). Overall, prevalence of hypertension was higher in men (8·7% [95% CI 8·2-9·6]) than in women (6·6% [6·0-6·9]), but with age increased to similar levels (at age 18 years 7·3% [6·2-8·6] and 4·3% [3·5-5·2]; at age 23-24 years 10·9% [9·3-12·6] and 9·5% [8·4-10·7] in men and women, respectively). After adjusting for factors associated with hypertension in the crude analysis, hypertension was associated with male sex (adjusted odds ratio 1·53 [95% CI 1·36-1·74]), increasing age (age 19-20 years 1·20 [1·00-1·44]; age 21-22 years 1·45 [1·20-1·75]; age 23-24 years 1·90 [1·57-2·30], vs age 18 years), and BMI of 30·0 kg/m2 or more (1·94 [1·53-2·47] vs 18·5-24·9 kg/m2). A BMI of 18·5 kg/m2 or less (0·79 [0·63-0·98] vs 18·5-24·9 kg/m2) and living with HIV (0·71 [0·55-0·92]) were associated with lower odds of hypertension. INTERPRETATION: Prevalence of elevated blood pressure is high among urban and peri-urban youth in Zimbabwe and increases rapidly with age. Further research is needed to understand drivers of blood pressure elevation and the extent of target organ damage in youth in Zimbabwe and similar sub-Saharan African settings, to guide implementation of prevention and management strategies.

RESUMO

OBJECTIVES: Chronic lung disease is a recognized complication in children with HIV. Acute respiratory exacerbations (ARE) are common among this group and cause significant morbidity. Exhaled nitric oxide (eNO) is a known marker of local airway inflammation. We investigated the association between eNO and ARE, biomarkers of systemic inflammation, and the effect of azithromycin on eNO levels. METHODS: Individuals aged 6-19 years with HIV-associated chronic lung disease in Harare, Zimbabwe, were enrolled in a placebo-controlled randomized trial investigating the effect of 48-week azithromycin treatment on lung function and ARE. eNO levels and biomarkers were measured at inclusion and after treatment in a consecutively enrolled subset of participants. Linear regression and generalized linear models were used to study associations between eNO and ARE, biomarkers, and the effect of azithromycin on eNO levels. RESULTS: In total, 172 participants were included in this sub-study, 86 from the placebo group and 86 from the azithromycin group. Participants experiencing at least one ARE during follow-up had significantly higher eNO levels at baseline than participants who did not (geometric mean ratio 1.13, 95% confidence interval [CI] 1.03-1.24, p = 0.015), adjusted for trial arm, age, sex and history of tuberculosis. Matrix metalloproteinase (MMP)-3, -7, and -10 were significantly associated with higher baseline eNO levels. At 48 weeks, azithromycin treatment did not affect eNO levels (geometric mean ratio 0.86, 95% CI 0.72-1.03, p = 0.103). CONCLUSION: Higher baseline eNO levels were a risk factor for ARE. eNO was associated with proinflammatory biomarkers previously found to contribute to the development of chronic lung disease. The potential use of eNO as a marker of inflammation and risk factor for ARE in HIV-associated chronic lung disease needs further investigation.

RESUMO

Impaired linear growth and slower pubertal growth can be associated with perinatal HIV infection. We characterised growth relative to population norms, among the full adolescent period in southern Africa to better understand processes leading to morbidity in adulthood. We conducted a secondary analysis of 945 adolescents aged 8-20 years from urban Malawi and Zimbabwe; we included children with HIV (CWH), an uninfected comparison group from a cohort study, and CWH with co-morbid chronic lung disease (CLD) from a randomised controlled trial. We used latent class analysis of anthropometric Z-scores generated from British 1990 reference equations at two annual time-points, to identify growth trajectory profiles and used multinomial logistic regression to identify factors associated with growth profiles. Growth faltering (one or more of weight-for-age, height-for-age, or BMI-for-age Z-scores < -2) occurred in 38% (116/303) of CWH from the cohort study, 62% (209/336) of CWH with CLD, and 14% (44/306) of HIV-uninfected participants. We identified seven different growth profiles, defined, relatively, as (1) average growth, (2) tall not thin, (3) short not thin, (4) stunted not thin, (5) thin not stunted, (6) thin and stunted and (7) very thin and stunted. Females in profile 3 exhibited the highest body fat percentage, which increased over 1 year. Males at older age and CWH especially those with CLD were more likely to fall into growth profiles 4-7. Improvements in height-for-age Z-scores were observed in profiles 6-7 over 1 year. Interventions to target those with the worst growth faltering and longer-term follow-up to assess the impact on adult health are warranted.

RESUMO

Introduction: Sexually transmitted infections (STIs) such as chlamydia, gonorrhoea, trichomoniasis, and syphilis, are associated with adverse birth outcomes. Treatment should be accompanied by partner services to prevent re-infection and break cycles of transmission. Partner services include the processes of partner notification (PN) as well as arranging for their attendance for testing and/or treatment. However, due to a complex mix of cultural, socio-economic, and health access factors, uptake of partner services is often very low, in many settings globally. Alternative strategies to facilitate partner services are therefore needed.The aim of this study is to assess the impact of a small financial incentive on uptake of partner services for STIs as part of antenatal care (ANC) services in Zimbabwe. Methods and analysis: This trial will be embedded within a prospective interventional study in Harare, aiming to evaluate integration of point-of-care diagnostics for STIs into ANC settings. One thousand pregnant women will be screened for chlamydia, gonorrhoea, trichomoniasis, and syphilis. All individuals with STIs will be offered treatment, risk reduction counselling, and client PN. Each clinic day will be randomised 1:1 to be an incentive or non-incentive day. On incentive days, participants diagnosed with a curable STI will be offered a PN slip, that when returned will entitle their partners to $3 (USD) in compensation. On non-incentive days, regular PN slips with no incentive are provided.The primary outcome measure is the proportion of individuals with at least one partner who returns for partner services based on administrative records. Secondary outcomes will include the number of days between index case diagnosis and the partner attending for partner services, uptake of PN slips by pregnant women, adverse birth outcomes in index cases, partners who receive treatment, and intervention cost. Registration: Pan African Clinical Trials Registry: PACTR202302702036850 (Approval date 18 th February 2022).

RESUMO

Background: Young people are at high risk of sexually transmitted infections (STIs). We report STI testing uptake, prevalence and incidence within a community-based integrated HIV and sexual and reproductive health service for youth, being evaluated in a cluster randomised trial in Zimbabwe. Methods: This paper reports the intervention findings of the cluster randomised trial whereby STI testing was offered to all service attendees (16-24 years) in 12 intervention clusters over 12 months between October 5, 2020, and December 17, 2021, in Zimbabwe. Testing for Chlamydia trachomatis [CT] and Neisseria gonorrhoeae [NG] was offered to males and females with results available in one week and follow-up of test-positive clients by telephone. Trichomonas vaginalis [TV] testing was offered to females only with same day results and treatment. Youth testing positive for any STI were offered partner notification slips and free treatment for partners. This trial was registered with ISRCTN Registry, ISRCTN15013425. Findings: Overall, 8549/9891 (86.1%) eligible youth accepted CT/NG testing. Prevalence of CT and NG was 14.7% (95% CI 13.6-15.8) and 2.8% (95% CI 2.2-3.6) respectively. Combined prevalence of CT, NG or TV in women was 23.2% (95% CI 21.5-25.0). After adjusting for cluster, age and sex, the odds of NG were increased in those living with HIV (aOR 3.14, 95% CI 2.21-4.47). The incidence rate among those who initially tested negative for CT or NG was 25.6/100PY (95% CI 20.6-31.8). CT/NG treatment uptake was 924/1526 (60.6%). TV treatment uptake was 483/489 (98.8%). A partner returned for treatment for 103/1807 clients (5.7%). Interpretation: Our findings show high acceptability of STI testing among youth. STI prevalence was high particularly among females and youth with HIV, underscoring the need for integration of HIV and STI services.

RESUMO

Partner notification (PN) is considered integral to the management of sexually transmitted infections (STI). Patient-referral is a common PN strategy and relies on index cases notifying and encouraging their partners to access treatment; however, it has shown limited efficacy. We conducted a mixed methods study to understand young people's experiences of PN, particularly the risks and challenges encountered during patient-referral. All young people (16-24 years) attending a community-based sexual and reproductive health service in Zimbabwe who were diagnosed with an STI were counselled and offered PN slips, which enabled their partners to access free treatment at the service. PN slip uptake and partner treatment were recorded. Among 1807 young people (85.0% female) offered PN slips, 745 (41.2%) took up ≥1 PN slip and 103 partners (5.7%) returned for treatment. Most participants described feeling ill-equipped to counsel and persuade their partners to seek treatment. Between June and August 2021, youth researchers conducted in-depth interviews with 41 purposively selected young people diagnosed with an STI to explore their experiences of PN. PN posed considerable social risks, threatening their emotional and physical safety. Except for a minority in long-term, publicly acknowledged relationships, participants did not expect PN would achieve successful outcomes. Public health discourse, which constructs PN as "the right thing to do", influenced participants to adopt narratives that concealed the difficulties of PN and their unmet needs. Urgent interrogation is needed of whether PN is a suitable or constructive strategy to continue pursuing with young people. To improve the outcomes of preventing reinfection and onward transmission of STIs, we must consider developing alternative strategies that better align with young people's lived experiences.Plain language summary Partner notification is a public health strategy used to trace the sexual partners of people who have received a sexually transmitted infection (STI) diagnosis. It aims to interrupt the chains of STI transmission and prevent reinfection by treating both the person diagnosed and their sexual partners. The least effective but most common partner notification strategy used in many resource-limited settings is called "patient referral". This involves a sexual healthcare provider encouraging the person diagnosed to give a "partner notification slip" to their potentially exposed sexual partner/s and persuading them to access treatment. This research sought to better understand young people's experiences of partner notification, particularly the risks and challenges they faced during patient-referral.All young people (16-24 years) attending a community-based sexual and reproductive health service in Zimbabwe who were diagnosed with an STI were counselled and offered PN slips, which enabled their partners to access free treatment at the service. Young people trained as researchers interviewed 41 young people who had received a STI diagnosis to explore their experiences of partner notification.Only a small number (5.7%) of the partners of those who took a slip attended the service for treatment. Most participants felt they did not have the preparation, skills, or resources to persuade their partners to seek treatment. Many described negative experiences during and after partner notification, including relationship breakdown, reputation damage, and physical violence.These findings suggest that we should reconsider if partner notification is suitable or effective for use with young people. We should explore alternative approaches that do not present risks to young people's social, emotional, and physical safety and well-being.

RESUMO

INTRODUCTION: COVID-19 vaccine acceptance research has mostly originated from high-income countries and reasons why youth may not get vaccinated may differ in low-income settings. Understanding vaccination coverage across different population groups and the sociocultural influences in healthcare delivery is important to inform targeted vaccination campaigns. METHODS: A population-based survey was conducted in 24 communities across three provinces (Harare, Bulawayo and Mashonaland East) in Zimbabwe between October 2021 and June 2022. Youth aged 18-24 years were randomly selected using multistage sampling. Sociodemographic characteristics, COVID-19 vaccination uptake and reasons for non-uptake were collected, and odds of vaccination was investigated using logistic regression. RESULTS: 17 682 youth were recruited in the survey (n=10 742, 60.8% female). The median age of participants was 20 (IQR: 19-22) years. Almost two thirds (n=10 652, 60.2%) reported receiving at least one dose of COVID-19 vaccine. A higher proportion of men than women had been vaccinated (68.9% vs 54.7%), and vaccination prevalence increased with age (<19 years: 57.5%, 20-22: 61.5%, >23: 62.2%). Lack of time to get vaccinated, belief that the vaccine was unsafe and anxiety about side effects (particularly infertility) were the main reasons for not getting vaccinated. Factors associated with vaccination were male sex (OR=1.69, 95% CI 1.58 to 1.80), increasing age (>22 years: OR=1.12, 95% CI 1.04 to 1.21), education level (postsecondary: OR=4.34, 95% CI 3.27 to 5.76) and socioeconomic status (least poor: OR=1.32, 95% CI 1.20 to 1.47). CONCLUSION: This study found vaccine inequity across age, sex, educational attainment and socioeconomic status among youth. Strategies should address these inequities by understanding concerns and tailoring vaccine campaigns to specific groups.

RESUMO

Background: Achieving good menstrual health (MH), integral to women's well-being, remains a challenge. This study examined MH services uptake (including information, analgesics, and a choice of MH products - the menstrual cup and reusable pads) and sustained use of MH products within an integrated sexual and reproductive health intervention for young people in Zimbabwe. Methods: This study was embedded within a cluster randomised trial of integrated sexual and reproductive health services (CHIEDZA) in three provinces (Harare, Mashonaland East, and Bulawayo). The study collected qualitative and quantitative data from female clients aged 16-24 years, who accessed CHIEDZA from April 2019 - March 2022. Uptake of MH information, products, and analgesics and other services was tracked for each client. Descriptive statistics and logistic regression were used to investigate MH service uptake and product choice and use over time, and the factors associated with these outcomes. Thematic analysis of focus group discussions and interviews were used to further explore providers' and participants' experiences of the MH service and CHIEDZA intervention. Results: Overall, 36991 clients accessed CHIEDZA of whom 27725 (75%) were female. Almost all (n = 26448; 95.4%) took up the MH service at least once: 25433 took up an MH product with the majority (23346; 92.8%) choosing reusable pads. The uptake of cups varied across province with Bulawayo province having the highest uptake (13.4%). Clients aged 20-24 years old were more likely to choose cups than reusable pads compared with those aged 16-19 years (9.4% vs 6.0%; p < 0.001). Over the implementation period, 300/1819 (16.5%) of clients swapped from the menstrual cup to reusable pads and 83/23346 (0.4%) swapped from reusable pads to the menstrual cup. Provision of the MH service encouraged uptake of other important SRH services. Qualitative findings highlighted the provision of free integrated SRH and MH services that included a choice of MH products and analgesics in a youth-friendly environment were key to high uptake and overall female engagement with SRH services. Conclusions: High uptake demonstrates how the MH service provided much needed access to MH products and information. Integration of MH within an SRH intervention proved central to young women accessing other SRH services.

RESUMO

PURPOSE: Mobile technology is increasingly being used to widen access to and support the delivery of public health interventions. Human immunodeficiency viruses (HIV) self-testing (HIVST) enables individuals to have autonomy. We evaluated the feasibility of a novel application called ITHAKA to support HIVST among youth aged 16-24 years in Zimbabwe. METHODS: This study was nested within a trial of community-based delivery of integrated HIV and sexual and reproductive health services called CHIEDZA. Youth accessing CHIEDZA were offered provider-delivered HIV testing or HIVST supported by ITHAKA, either on a tablet on-site at a community centre or on their mobile phone off-site. ITHAKA incorporated pre and post-test counselling, and instructions for conducting the test and the appropriate actions to take depending on test result, including reporting HIV test results to health providers. The outcome was completion of the testing journey. Semistructured interviews with CHIEDZA providers explored the perceptions of and experiences with the application. RESULTS: Between April and September 2019, of the 2,181 youth who accepted HIV testing in CHIEDZA, 128 (5.8%) initiated HIVST (the remainder opting for provider-delivered testing) using ITHAKA. Nearly all who performed HIVST on-site (108/109 (99.1%)) compared to only 9/19 (47.4%) who tested off-site completed their testing journey. Low digital literacy, lack of agency, erratic network coverage, lack of dedicated phone ownership, the limited functionality of smartphones challenged implementation of ITHAKA. DISCUSSION: Digitally supported HIVST had low uptake among youth. The feasibility and usability of digital interventions should be carefully assessed before implementation, paying careful attention to digital literacy, network availability, and access to devices.

RESUMO

BACKGROUND: The scale-up of antiretroviral therapy programmes has resulted in increased life expectancy of people with HIV in Africa. Little is known of the menopausal experiences of African women, including those living with HIV. We aimed to determine the prevalence and severity of self-reported menopause symptoms in women at different stages of menopause transition, by HIV status, and evaluate how symptoms are related to health-related quality of life (HRQoL). We further sought to understand factors associated with menopause symptoms. METHODS: A cross-sectional study recruited women resident in Harare, Zimbabwe, sampled by age group (40-44/45-49/50-54/55-60 years) and HIV status. Women recruited from public-sector HIV clinics identified two similarly aged female friends (irrespective of HIV status) with phone access. Socio-demographic and medical details were recorded and women staged as pre-, peri- or post-menopause. The Menopausal Rating Scale II (MRS), which classified symptom severity, was compared between those with and without HIV. Linear and logistic regression determined factors associated with menopause symptoms, and associations between symptoms and HRQoL. RESULTS: The 378 women recruited (193[51.1%] with HIV), had a mean (SD) age of 49.3 (5.7) years; 173 (45.8%), 51 (13.5%) and 154 (40.7%) were pre-, peri and post-menopausal respectively. Women with HIV reported more moderate (24.9% vs. 18.1%) and severe (9.7% vs. 2.6%) menopause symptoms than women without HIV. Peri-menopausal women with HIV reported higher MRS scores than those pre- and post-menopausal, whereas in HIV negative women menopausal stage was not associated with MRS score (interaction p-value = 0.014). With increasing severity of menopause symptoms, lower mean HRQoL scores were observed. HIV (OR 2.02[95% CI 1.28, 3.21]), mood disorders (8.80[2.77, 28.0]), ≥ 2 falls/year (4.29[1.18, 15.6]), early menarche (2.33[1.22, 4.48]), alcohol consumption (2.16[1.01, 4.62]), food insecurity (1.93[1.14, 3.26]) and unemployment (1.56[0.99, 2.46]), were all associated with moderate/severe menopause symptoms. No woman reported use of menopausal hormone therapy. CONCLUSIONS: Menopausal symptoms are common and negatively impact HRQoL. HIV infection is associated with more severe menopause symptoms, as are several modifiable factors, including unemployment, alcohol consumption, and food insecurity. Findings highlight an unmet health need in ageing women in Zimbabwean, especially among those living with HIV.

RESUMO

BACKGROUND: Index-linked HIV testing for children, whereby HIV testing is offered to children of individuals living with HIV, has the potential to identify children living with undiagnosed HIV. The "Bridging the Gap in HIV Testing and Care for Children in Zimbabwe" (B-GAP) study implemented and evaluated the provision of index-linked HIV testing for children aged 2-18 years in Zimbabwe. We conducted a process evaluation to understand the considerations for programmatic delivery and scale-up of this strategy. METHODS: We used implementation documentation to explore experiences of the field teams and project manager who delivered the index-linked testing program, and to describe barriers and facilitators to index-linked testing from their perspectives. Qualitative data were drawn from weekly logs maintained by the field teams, monthly project meeting minutes, the project coordinator's incident reports and WhatsApp group chats between the study team and the coordinator. Data from each of the sources was analysed thematically and synthesised to inform the scale-up of this intervention. RESULTS: Five main themes were identified related to the implementation of the intervention: (1) there was reduced clinic attendance of potentially eligible indexes due to community-based differentiated HIV care delivery and collection of HIV treatment by proxy individuals; (2) some indexes reported that they did not live in the same household as their children, reflecting the high levels of community mobility; (3) there were also thought to be some instances of 'soft refusal'; (4) further, delivery of HIV testing was limited by difficulties faced by indexes in attending health facilities with their children for clinic-based testing, stigma around community-based testing, and the lack of familiarity of indexes with caregiver provided oral HIV testing; (5) and finally, test kit stockouts and inadequate staffing also constrained delivery of index-linked HIV testing. CONCLUSIONS: There was attrition along the index-linked HIV testing cascade of children. While challenges remain at all levels of implementation, programmatic adaptations of index-linked HIV testing approaches to suit patterns of clinic attendance and household structures may strengthen implementation of this strategy. Our findings highlight the need to tailor index-linked HIV testing to subpopulations and contexts to maximise its effectiveness.

RESUMO

INTRODUCTION: Sexually transmitted infections (STIs) can cause serious morbidity, including pelvic inflammatory disease, and adverse pregnancy outcomes. In low/middle-income countries, limited laboratory infrastructure has resulted in a syndrome-based approach being used for management of STIs, which has poor sensitivity and specificity, leading to considerable underdiagnosis and overtreatment. The WHO has called for development and evaluation of strategies to inform replacement of syndromic management by diagnostic testing.The aim of this project is to evaluate a strategy of point-of-care testing for six STIs in antenatal care (ANC) in Zimbabwe. METHODS AND ANALYSIS: A prospective interventional study will be conducted in ANC clinics in Harare province, Zimbabwe. One thousand pregnant women will be recruited when registering for routine ANC. Alongside routine HIV and syphilis testing, participants will be offered an integrated screening package including testing for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV) and hepatitis B. All individuals with STIs will receive treatment, partner notification services, risk reduction counselling and referral if needed according to national guidelines. Gonorrhoea samples will be cultured and tested for antimicrobial resistance as per WHO enhanced gonococcal antimicrobial surveillance programme guidelines.The primary outcome measure is the composite prevalence of CT, NG, TV, syphilis and hepatitis B. A mixed-methods process evaluation and economic evaluation will be conducted to understand the acceptability, feasibility and cost-effectiveness of integrated STI testing, compared with standard of care (syndromic management). ETHICS AND DISSEMINATION: The study protocol was approved by the Medical Research Council of Zimbabwe, the Biomedical Research and Training Institute Institutional Review Board, and the London School of Hygiene & Tropical Medicine Research Ethics Committee. Results will be submitted to open-access peer-reviewed journals, presented at academic meetings and shared with participating communities and with national and international policymaking bodies. TRIAL REGISTRATION NUMBER: NCT05541081.

RESUMO

OBJECTIVES: While integral to women's physical and mental well-being, achieving good menstrual health (MH) remains a challenge for many women. This study investigated the effectiveness of a comprehensive MH intervention on menstrual knowledge, perceptions and practices among women aged 16-24 years in Harare, Zimbabwe. DESIGN: A mixed-methods prospective cohort study with pre-post evaluation of an MH intervention. SETTING: Two intervention clusters in Harare, Zimbabwe. PARTICIPANTS: Overall, 303 female participants were recruited, of whom 189 (62.4%) were seen at midline (median follow-up 7.0; IQR 5.8-7.7 months) and 184 (60.7%) were seen at endline (median follow-up 12.4; IQR 11.9-13.8 months). Cohort follow-up was greatly affected by COVID-19 pandemic and associated restrictions. INTERVENTION: The MH intervention provided MH education and support, analgesics, and a choice of menstrual products in a community-based setting to improve MH outcomes among young women in Zimbabwe. PRIMARY AND SECONDARY OUTCOMES: Effectiveness of a comprehensive MH intervention on improving MH knowledge, perceptions, and practices among young women over time. Quantitative questionnaire data were collected at baseline, midline, and endline. At endline, thematic analysis of four focus group discussions was used to further explore participants' menstrual product use and experiences of the intervention. RESULTS: At midline, more participants had correct/positive responses for MH knowledge (adjusted OR (aOR)=12.14; 95% CI: 6.8 to 21.8), perceptions (aOR=2.85; 95% CI: 1.6 to 5.1) and practices for reusable pads (aOR=4.68; 95% CI: 2.3 to 9.6) than at baseline. Results were similar comparing endline with baseline for all MH outcomes. Qualitative findings showed that sociocultural norms, stigma and taboos around menstruation, and environmental factors such as limited access to water, sanitation and hygiene facilities affected the effect of the intervention on MH outcomes. CONCLUSIONS: The intervention improved MH knowledge, perceptions and practices among young women in Zimbabwe, and the comprehensive nature of the intervention was key to this. MH interventions should address interpersonal, environmental and societal factors. TRIAL REGISTRATION NUMBER: NCT03719521.
