Participatory approaches involving community and healthcare providers in family planning/contraceptive information and service provision: a scoping review.
As efforts to address unmet need for family planning and contraception (FP/C) accelerate, voluntary use, informed choice and quality must remain at the fore. Active involvement of affected populations has been recognized as one of the key principles in ensuring human rights in the provision of FP/C and in improving quality of care. However, community participation continues to be inadequately addressed in large-scale FP/C programmes. Community and healthcare providers’ unequal relationship can be a barrier to successful participation. This scoping review identifies participatory approaches involving both community and healthcare providers for FP/C services and analyzes relevant evidence. The detailed analysis of 25 articles provided information on 28 specific programmes and identified three types of approaches for community and healthcare provider participation in FP/C programmes. The three approaches were: (i) establishment of new groups either health committees to link the health service providers and users or implementation teams to conduct specific activities to improve or extend available health services, (ii) identification of and collaboration with existing community structures to optimise use of health services and (iii) operationalization of tools to facilitate community and healthcare provider collaboration for quality improvement. Integration of community and healthcare provider participation in FP/C provision were conducted through FP/C-only programmes, FP/C-focused programmes and/or as part of a health service package. The rationales behind the interventions varied and may be multiple. Examples include researcher-, NGO- or health service-initiated programmes with clear objectives of improving FP/C service provision or increasing demand for services; facilitating the involvement of community members or service users and, in some cases, may combine socio-economic development and increasing self-reliance or control over sexual and reproductive health. Although a number of studies reported increase in FP/C knowledge and uptake, the lack of robust monitoring and evaluation mechanisms and quantitative and comparable data resulted in difficulties in generating clear recommendations. It is imperative that programmes are systematically designed, evaluated and reported
Protocol: Mapping social networks, social influence and sexual health among youth in rural KwaZulu-Natal, the Sixhumene cohort study [version 1; peer review: awaiting peer review]
Background: Sexual behaviour and sexually transmitted infections are strongly affected by social connections, and interventions are often adapted more readily when diffused through social networks. However, evidence on how young people acquire ideas and change behaviour through the influence of important social contacts is not well understood in high-HIV-prevalence settings, with the result that past peer-led HIV-prevention interventions have had limited success. /
Methods: We therefore designed a cohort study (named Sixhumene or ‘we are connected’) to follow young people in three rural and small-town communities in uMkhanyakude district, KwaZulu-Natal, South Africa, and the people that these youth identify as important in their lives. We will interview them five times over three years, at each visit collecting information on their socioeconomic, social and sexual health lives, and testing them for HIV and herpes simplex virus 2 (HSV-2). We will use this information to understand how these young people’s sexual health decisions are formed. This will include evaluating how poor sexual health outcomes are correlated across social networks, how youth mimic the attitudes and behaviours of those around them, who is at greatest risk of acquiring HIV and HSV-2, and who might be most influential within communities and thus best able to promote protective interventions. /
Discussion: The information gathered through this study will allow us to describe social connection and influence spread through these real-world social networks, and how this leads to sexual health outcomes. Sixhumene will provide vital inputs for mathematical models of communities and spreading processes, as well as inform the development of effective interventions to protect the sexual health of community members through appropriate targeting with optimised messaging requiring fewer resources
Cluster randomised controlled trial to determine the effect of peer delivery HIV self-testing to support linkage to HIV prevention among young women in rural KwaZulu-Natal, South Africa: a study protocol.
INTRODUCTION: A cluster randomised controlled trial (cRCT) to determine whether HIV self-testing (HIVST) delivered by peers either directly or through incentivised peer-networks, could increase the uptake of antiretroviral therapy and pre-exposure prophylaxis (PrEP) among young women (18 to 24 years) is being undertaken in an HIV hyperendemic area in KwaZulu-Natal, South Africa. METHODS AND ANALYSIS: A three-arm cRCT started mid-March 2019, in 24 areas in rural KwaZulu-Natal. Twenty-four pairs of peer navigators working with ~12 000 young people aged 18 to 30 years over a period of 6 months were randomised to: (1) incentivised-peer-networks: peer-navigators recruited participants 'seeds' to distribute up to five HIVST packs and HIV prevention information to peers within their social networks. Seeds receive an incentive (20 Rand = US$1.5) for each respondent who contacts a peer-navigator for additional HIVST packs to distribute; (2) peer-navigator-distribution: peer-navigators distribute HIVST packs and information directly to young people; (3) standard of care: peer-navigators distribute referral slips and information. All arms promote sexual health information and provide barcoded clinic referral slips to facilitate linkage to HIV testing, prevention and care services. The primary outcome is the difference in linkage rate between arms, defined as the number of women (18 to 24 years) per peer-navigators month of outreach work (/pnm) who linked to clinic-based PrEP eligibility screening or started antiretroviral, based on HIV-status, within 90 days of receiving the clinic referral slip. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Boards at the WHO, Switzerland (Protocol ID: STAR CRT, South Africa), London School of Hygiene and Tropical Medicine, UK (Reference: 15 990-1), University of KwaZulu-Natal (BFC311/18) and the KwaZulu-Natal Department of Health (Reference: KZ_201901_012), South Africa. The findings of this trial will be disseminated at local, regional and international meetings and through peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT03751826; Pre-results
Persistently high incidence of HIV and poor service uptake in adolescent girls and young women in rural KwaZulu-Natal, South Africa prior to DREAMS.
BACKGROUND: Adolescent girls and young women (AGYW) bear the brunt of the HIV epidemic in South Africa. 'DREAMS' aims to reduce HIV incidence through multi-level combination prevention. We describe HIV incidence and uptake of HIV and sexual reproductive health (SRH) by AGYW in KwaZulu-Natal (KZN), prior to DREAMS. METHODS: Longitudinal and cross-sectional analysis of women (15-24 year old) in a population-based HIV incidence cohort within a demographic surveillance site in KZN. Observation time for HIV incidence was person-years at risk while resident. "Current use of contraceptives" and "having an HIV test in the past 12 months" was compared between 2011 and 2015. RESULTS: In 2015, HIV prevalence was 11.0% and 34.1% and HIV incidence (2011-2015) was 4.54% (95%CI:3.89-5.30) and 7.45% (95%CI:6.51-8.51) per year in 15-19 and 20-24 year olds respectively, with no significant decline compared to 2006-2010. In 2015, 90.7% of 20-24-year-olds were unemployed, 36.4% and 51.7% of 15-19 and 20-24 year olds reported recent migration; 20.9% and 72.6% of 15-19 and 20-24 year olds had ever been pregnant. In 2015, less than 50% reported condom-use at last sex, 15.0% of 15-19 year olds and 48.9% of 20-24 year olds were currently using contraception and 32.0% and 66.7% of 15-19 and 20-24 year olds had tested for HIV in the past 12 months. There had been no improvement compared to 2011. Factors associated with AGYW testing for HIV in the past 12 months were, survey year-2011 more likely than 2015 (aOR = 0.50), number of partners (aOR = 3.25), ever been pregnant (aOR = 2.47) and knowing where to find ART (aOR = 1.54). Factors associated with contraception use were being older (aOR = 4.83); ever been pregnant (aOR = 12.62); knowing where to get ART (aOR = 1.79) and having had an HIV test in past 12 months (aOR = 1.74). CONCLUSION: Prior to DREAMS, HIV incidence in AGYW was high. HIV and SRH service uptake did not improve and was suboptimal. Findings highlight the need for combination HIV prevention programmes for AGYW in this economically vulnerable area
Cluster randomised controlled trial to determine the effect of peer delivery HIV self-testing to support linkage to HIV prevention among young women in rural KwaZulu-Natal, South Africa: study protocol
Abstract: A cluster randomised controlled trial (cRCT) to determine whether HIV self-testing (HIVST) delivered by peers either directly or through incentivised peer-networks, could increase the uptake of antiretroviral therapy and pre-exposure prophylaxis (PrEP) among young women (18 to 24 years) is being undertaken in an HIV hyperendemic area in KwaZulu-Natal, South Africa..
Prevalence of sexually transmitted infections among young people in South Africa: A nested survey in a health and demographic surveillance site.
BACKGROUND: Sexually transmitted infections (STIs) and bacterial vaginosis (BV) are associated with increased transmission of HIV, and poor reproductive and sexual health. The burden of STIs/BV among young people is unknown in many high HIV prevalence settings. We conducted an acceptability, feasibility, and prevalence study of home-based sampling for STIs/BV among young men and women aged 15-24 years old in a health and demographic surveillance site (HDSS) in rural KwaZulu-Natal, South Africa. METHODS AND FINDINGS: A total of 1,342 young people, stratified by age (15-19 and 20-24 years) and sex were selected from the HDSS sampling frame; 1,171/1,342 (87%) individuals had ≥1 attempted home visit between 4 October 2016 and 31 January 2017, of whom 790 (67%) were successfully contacted. Among the 645 who were contacted and eligible, 447 (69%) enrolled. Consenting/assenting participants were interviewed, and blood, self-collected urine (men), and vaginal swabs (women) were tested for herpes simplex virus type 2 (HSV-2), chlamydia, gonorrhoea, syphilis, trichomoniasis, and BV. Both men and women reported that sample collection was easy. Participants disagreed that sampling was painful; more than half of the participants disagreed that they felt anxious or embarrassed. The weighted prevalence of STIs/BV among men and women, respectively, was 5.3% and 11.2% for chlamydia, 1.5% and 1.8% for gonorrhoea, 0% and 0.4% for active syphilis, 0.6% and 4.6% for trichomoniasis, 16.8% and 28.7% for HSV-2, and 42.1% for BV (women only). Of the women with ≥1 curable STI, 75% reported no symptoms. Factors associated with STIs/BV included having older age, being female, and not being in school or working. Among those who participated in the 2016 HIV serosurvey, the prevalence of HIV was 5.6% among men and 19% among women. Feasibility was impacted by the short study duration and the difficulty finding men at home. CONCLUSIONS: A high prevalence of STIs/BV was found in this rural setting with high HIV prevalence in South Africa. Most STIs and HIV infections were asymptomatic and would not have been identified or treated under national syndromic management guidelines. A nested STI/BV survey within a HDSS proved acceptable and feasible. This is a proof of concept for population-based STI surveillance in low- and middle-income countries that could be utilised in the evaluation of STI/HIV prevention and control programmes
Evaluating use of mass-media communication intervention 'MTV-Shuga' on increased awareness and demand for HIV and sexual health services by adolescent girls and young women in South Africa: an observational study
OBJECTIVE: To investigate the effect of exposure to MTV Shuga:Down South' (MTVShuga-DS) during the scale-up of combination HIV-prevention interventions on awareness and uptake of sexual reproductive health (SRH) and HIV-prevention services by adolescent girls and young women (AGYW). DESIGN: One longitudinal and three cross-sectional surveys of representative samples of AGYW. SETTING: AGYW in four South African districts with high HIV prevalence (>10%) (May 2017 and September 2019). PARTICIPANTS: 6311 AGYW aged 12-24. MEASURES: Using logistic regression, we measured the relationship between exposure to MTV Shuga-DS and awareness of pre-exposure prophylaxis (PrEP), condom use at last sex, uptake of HIV-testing or contraception, and incident pregnancy or herpes simplex virus 2 (HSV-2) infection. RESULTS: Within the rural cohort 2184 (85.5%) of eligible sampled individuals were enrolled, of whom 92.6% had at least one follow-up visit; the urban cross-sectional surveys enrolled 4127 (22.6%) of eligible sampled individuals. Self-report of watching at least one MTV Shuga-DS episode was 14.1% (cohort) and 35.8% (cross-section), while storyline recall was 5.5% (cohort) and 6.7% (cross-section). In the cohort, after adjustment (for HIV-prevention intervention-exposure, age, education, socioeconomic status), MTVShuga-DS exposure was associated with increased PrEP awareness (adjusted OR (aOR) 2.06, 95% CI 1.57 to 2.70), contraception uptake (aOR 2.08, 95% CI 1.45 to 2.98) and consistent condom use (aOR 1.84, 95% CI 1.24 to 2.93), but not with HIV testing (aOR 1.02, 95% CI 0.77 to 1.21) or acquiring HSV-2 (aOR 0.92, 95% CI 0.61 to 1.38). In the cross-sections, MTVShuga-DS was associated with greater PrEP awareness (aOR 1.7, 95% CI 1.20 to 2.43), but no other outcome. CONCLUSIONS: Among both urban and rural AGYW in South Africa, MTVShuga-DS exposure was associated with increased PrEP awareness and improved demand for some HIV prevention and SRH technologies but not sexual health outcomes. However, exposure to MTVShuga-DS was low. Given these positive indications, supportive programming may be required to raise exposure and allow future evaluation of edu-drama impact in this setting
HIV serostatus, inflammatory biomarkers and the frailty phenotype among older people in rural KwaZulu-Natal, South Africa.
Objective: We compared the prevalence of frailty by HIV serostatus and related biomarkers to the modified frailty phenotype among older individuals in a rural population in South Africa. Methods: Questionnaire data were from a cohort of people living with HIV (PWH) on antiretroviral therapy (ART) and HIV-uninfected people aged 50 years and older sampled from the Africa Health Research Institute Demographic Health and Surveillance area in northern KwaZulu-Natal. The prevalence of frailty was compared using five categories: (1) physical activity; (2) mobility; (3) fatigue; (4) gait speed; and (5) grip strength, and assessed for demographic, clinical, and inflammatory correlates of frailty. Results: Among 614 individuals in the study, 384 (62.5%) were women. The median age at study enrolment was 64 years [Interquartile range (IQR) (58.6-72.0)]. 292 (47.6%) were PWH. 499 (81%) were classified as either pre-frail or frail. 43 (7%) were frail and HIV positive, 185 (30%) were pre-frail and HIV positive, 57 were frail and HIV negative and 214 (35%) were pre-frail and HIV negative. Frailty was similar for HIV negative and PWH (17.7% vs 14.7%, p = 0.72). Women were more likely to be frail (18.3% vs 13.04%, p = 0.16). The prevalence of frailty increased with age for both HIV groups. In the multivariable analysis, the odds of being frail were higher in those aged 70 years and above than those aged between 50 and 59 years (p < 0.001). Females were less likely to be pre-frail than males (p < 0.001). There was no association between any of the inflammatory biomarkers and frailty and pre-frailty. Conclusion: In this population, the prevalence of frailty is similar for PWH and people without HIV, but higher for women than men. These data suggest that the odds of developing frailty is similar for PWH over the age of 50 years, who survive into older age, as for people without HIV
Prevalence of Curable Sexually Transmitted Infections in a Population-Representative Sample of Young Adults in a High HIV Incidence Area in South Africa
BACKGROUND: Recent population-representative estimates of sexually transmitted infection (STI) prevalence in high HIV burden areas in southern Africa are limited. We estimated the prevalence and associated factors of 3 STIs among adolescents and young adults (AYA) in rural South Africa. METHODS: Between March 2020 and May 2021, a population-representative sample of AYA aged 16 to 29 years were randomly selected from a Health and Demographic Surveillance Site in rural KwaZulu-Natal, South Africa, for a 2 × 2 factorial randomized controlled trial. Participants in 2 intervention arms were offered baseline testing for gonorrhea, chlamydia, and trichomoniasis using GeneXpert. Prevalence estimates were weighted for participation bias, and logistic regression models were used to assess factors associated with STIs. RESULTS: Of 2323 eligible AYA, 1743 (75%) enrolled in the trial. Among 863 eligible for STI testing, 814 (94%) provided specimens (median age of 21.8 years, 52% female, and 71% residing in rural areas). Population-weighted prevalence estimates were 5.0% (95% confidence interval [CI], 4.2%-5.8%) for gonorrhea, 17.9% (16.5%-19.3%) for chlamydia, 5.4% (4.6%-6.3%) for trichomoniasis, and 23.7% (22.2%-25.3%) for any STI. In multivariable models, female sex (adjusted odds ratio [aOR], 2.24; 95% CI, 1.48-3.09) and urban/periurban (vs. rural) residence (aOR, 1.48; 95% CI, 1.02-2.15) were associated with STIs; recent migration was associated with lower odds of STI (aOR, 0.37; 95% CI, 0.15-0.89). Among those with an STI, 53 (31.0%) were treated within 7 days; median time to treatment was 11 days (interquartile range, 6-77 days). CONCLUSIONS: We identified a high prevalence of curable STIs among AYA in rural South Africa. Improved access to STI testing to enable etiologic diagnosis and rapid treatment is needed
