4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 37 Objective: Peer education has largely been a community-based intervention within the 6 7 38 voluntary medical male circumcision (VMMC) – adolescent sexual and reproductive health 8 9 10 39 (ASRH) linkages pilot project in Bulawayo and Mount Darwin, Zimbabwe since 2016. 11 12 40 However, little is known if benefits extend beyond information-giving. We assessed the 13 14 41 extent of and factors affecting referral and receipt of HIV testing services (HTS), 15 16 42 contraception, diagnosis and treatment of sexually transmitted infections (STIs) and VMMC 17 18 For peer review only 19 43 services by young people (10 – 24 years) counselled by peer educators in the two project 20 21 44 areas during October – December 2018. 22 23 24 45 Design: A cohort study utilizing the project’s routinely collected secondary data. 25 26 27 46 Setting: All the ASRH and VMMC sites in Mt Darwin and Bulawayo. 28 29 30 47 Participants: 95 peer educators. 31 32 33 34 48 Primary outcome measures: The censor date for assessing receipt of services was 31 35 49 January 2019. Factors affecting non-referral and non-receipt of services were assessed by 36 http://bmjopen.bmj.com/ 37 50 log-binomial regression. Adjusted risk ratios (aRR) were calculated. 38 39 40 51 Results: Of the 3370 counseled, 65% were referred for at-least one service. 58% of the 41 42 52 counseled males were referred for VMMC. Other services had 5-13% referrals. Non-referral 43 44 53 for HTS decreased with clients’ age(aRR:~0.9) but higher among group-counselled than on September 30, 2021 by guest.

Counseling by male peers(aRR:0.77) and rural 47 54 48 49 55 location(aRR:0.61) reduced the risks of non-referral for VMMC while age increased 50 51 56 it(aRR≥1.59). Receipt of services was high at 64-80% except for those referred for STIs 52 53 57 (39%). Group counseling and rural location(aRR:~0.52) and male peer educators(aRR:0.76) 54 55 56 58 reduced risk of non-receipt of VMMC. Rural location increased risk of non-receipt of 57 58 59 contraception(aRR:3.18) while marriage reduced it(aRR:0.20). 59 60 3

We define it as a structured 47 48 101 process of sharing of relevant information, values and behaviours among members of similar 49 50 102 status, in an appropriate setting for both the educator and learner. Following a series of 51 52 53 103 reviews, peer education has been noted to be an effective youth-led approach for influencing 54 55 104 positive behavioural outcomes among beneficiaries, if given appropriate support systems and 56 57 105 contextualized to different settings and needs of beneficiaries.(7,8) Peer education has been 58 59 60 5

In 2017, the scope of this project was expanded to engage youth peer educators 22 23 115 in promoting referral and receipt of SRH and VMMC services in Bulawayo and Mount 24 25 116 Darwin districts. Informed by Michielsen et al’s review(12), the re-designing incorporated 26 27 28 117 provision of an updated training that introduced relevant tools for delivering the messages 29 30 118 (distribution of information, education and communication materials and social media 31 32 119 platforms such as facebook and WhatsApp), which defined a clear referral pathway 33 34 120 (including referral forms, tracking and two-way feedback mechanism) and provision of 35 36 http://bmjopen.bmj.com/ 37 121 adequate tools for documentation. 38 39 40 122 Since the re-designing of the peer education component, no study has been conducted to 41 42 123 determine the effect of peer educators beyond just providing information to their peers. 43 44 Within this background, we carried out a study to assess the referral and receipt of HIV on September 30, 2021 by guest.

The health facility approach 28 29 140 required every facility to establish and equip special rooms (youth-friendly corners). The 30 31 141 community approach involved establishment of ‘community youth centres (CYCs)’ whilst 32 33 34 142 the school-based approach focussed on the provision of life skills education and counselling 35 36 143 mainly by teachers. http://bmjopen.bmj.com/ 37 38 144 39 40 145 In 2015, an extensive review of the 2010-2015 interventions in Zimbabwe was conducted so 41 42 43 146 as to inform the development of the National ASRH Strategy II: 2016-2020.(14) One of the 44 on September 30, 2021 by guest.

Of these, factors associated with non-referral 14 15 232 were assessed for HTS and VMMC services only. Factors associated with non-referrals for 16 17 contraception and STI diagnosis and treatment were not analyzed as it was not possible to 18 233 For peer review only 19 20 234 establish the appropriate denominator defining the eligibility for these services.

Downloaded from 5 246 There were 95 peer educators (52% males) in the study sites with a median age of 22 years 6 7 247 (range: 15-24). A total of 3370 young people received counselling services from the peer 8 9 10 248 educators (Table 1). Forty percent of young people were aged 15-19 years, with the majority 11 12 249 being males (66%) and single (98%).

Sixty five percent of the young people counselled were 24 25 254 referred for SRH services. Of those referred, 77% had been referred for only one service, 26 27 28 255 with the rest being referred for two or more services. Majority (75%) of those referred 29 30 256 received the services they had been referred for. 31 32 33 257 Of the males counselled, 58% were referred for VMMC services, of whom, 69% received the 34 35 36 258 services. The other services for which the adolescents were referred for include HIV testing http://bmjopen.bmj.com/ 37 38 259 (13%), contraception (13%) and diagnosis and treatment of STIs (5%). Among the services 39 40 260 referred for, the receipt for STI services was lowest (39%). 41 42 43 261 Factors associated with non-referrals for HTS and VMMC 44 on September 30, 2021 by guest.

1 2 289 DISCUSSION 3

4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 290 This study, the first one assessing the role of the peer educators in the referral and receipt of 6 7 291 selected SRH and VMMC services among young people in Zimbabwe found relatively 8 9 10 292 moderate levels of referrals, particularly for VMMC services. However, for those referred, 11 12 293 receipt of the services was high except for STI diagnosis and treatment. Majority of the 13 14 294 referred clients had been referred for just one service, perhaps indicating limited counselling 15 16 295 or reflecting the lack of need. The risk of not being referred for HTS services decreased 17 18 For peer review only 19 296 slightly with older age of clients, though for VMMC services younger aged adolescents were 20 21 297 more likely to be referred. Slightly increased non-referral for HTS services was observed in 22 23 298 clients who underwent group counseling sessions as compared to individual sessions. With 24 25 26 299 regard to VMMC services, those counseled by male peer educators were more likely to be 27 28 300 referred and to receive, likewise to the clients in the rural district. Rural setting increased risk 29 30 301 of not receiving contraception services while being married reduced this risk. 31 32 33 302 The low referral for diagnosis and treatment of STIs might have been influenced by: 1) lack 34 35 36 303 of confidence by peer educators in determining the need for referral. 2) limited self-reports of http://bmjopen.bmj.com/ 37 38 304 STI-like symptoms. In any population, only a minority will have STI or STI - like symptoms 39 40 305 and referrals rates may be low. However, the low receipt of the diagnosis and treatment of 41 42 43 306 STIs services among the referred clients might have been due to the associated user fees 44 on September 30, 2021 by guest. Protected copyright. 45 307 levied (mostly in council clinics and hospitals) in both the rural and urban settings.(17),(18) 46 47 308 Abolishing or largely subsidizing these costs, while maintaining or sustaining supply and 48 49 309 diagnostics may improve receipt of services by young people. 50 51 52 53 310 Low risk perception among early adolescents has been established to be one of the barriers 54 55 311 for referral and receipt of HTS services.(19) Other studies have also shown that demand for 56 57 312 HTS services are reduced in adolescents who require parental/guardian consent, especially 58 59 60 14

Downloaded from 5 6 315 client’s age increases. Individualized or client-centered counseling has been established to be 7 8 316 a more effective approach for HTS and post-test services than group counseling,(20) as 9 10 11 317 demonstrated also by this study. 12 13 318 14 15 319 Group counseling sessions may have provided an opportunity for client peer influence on 16 17 receipt of VMMC services. Counseling by male peer educators may also encourage openness 18 320 For peer review only 19 20 321 among the male clients leading to more referral and receipt of VMMC services. As regards 21 22 322 contraception, urban areas present more convenient service delivery points for accessing 23 24 323 contraceptives than rural areas, explaining why non-receipt is lower in the urban setups. 25 26 , 27 324 Myths on the association between modern contraception and future infertility(21) (22) may 28 29 325 have resulted in the higher non-receipt rates of contraception among the adolescent girls 30 31 326 referred. This belief may be more common in the rural setups and at times is propagated by 32 33 , 34 327 other health workers.(22) (17) 35 36 http://bmjopen.bmj.com/ 37 328 Strengths: This study had several strengths. We included all the clients who were counselled 38 39 329 by peer educators during the study period in the two project districts, which were the only 40 41 330 districts implementing this intervention in the whole country. As we used routine programme 42 43 44 331 data, the findings are likely a true reflection of the situation. The data was extracted into on September 30, 2021 by guest.

First, due to deficiencies in 57 58 337 documentation in the peer educator registers, we could not determine if the reason for non- 59 60 15

1 338 referral (for VMMC or HTS) was related to ‘need’, that is, they had already received VMMC 2 3

4 339 or HTS services before. We, therefore couldn’t exclude clients not in need from the analysis. BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 6 340 In certain circumstances, like referral for contraception and STI diagnosis and treatment, we 7 8 341 could not perform further analyses as it was not possible to establish the appropriate 9 10 11 342 denominator defining the eligibility for these services. Second, we were not able to establish 12 13 343 exact reasons for non-referral and non-receipt of services. This requires qualitative and 14 15 344 youth-led study approaches. Third, due to small sample size of those referred for STI 16 17 diagnosis and treatment, we lacked statistical power to carry out further analyses. Many 18 345 For peer review only 19 20 346 reviews on peer education have largely focused on assessing the designs or models of peer 21 22 347 education without focusing on the outputs and the immediate positive outcomes of peer 23 24 348 education in relation to receipt of diagnosis and treatment of STIs, HTS, contraception and 25 26 27 349 VMMC services. Therefore, there were no study results to compare with. Whilst the results 28 29 350 and conclusions of this study may be used in different peer education interventions, they 30 31 351 cannot be generalised. 32 33 34 352 Implications: The study has the following implications: 35 36 http://bmjopen.bmj.com/ 37 38 353  There is need for a review of peer education data collection tools to capture more 39 40 354 client and peer educator data, for example, on details and quality of sessions and 41 42 355 eligibility of clients for the various services in line with the recently adapted revised 43 44 on September 30, 2021 by guest. Protected copyright. 45 356 international guidelines on CSE in Zimbabwe.(24) The review will also need to be 46 47 357 followed with refresher training on the new concepts. This will help in determining 48 49 358 actual output and factors associated with it. 50 51 52 359  The project needs to consider integrating parent-child communication interventions 53 54 55 360 into the VMMC – ASRH linkages project so as to mobilize parents to support the 56 57 361 young people to access services (both psychosocially and financially).

Downloaded from 5 6 7 364  While HTS services are better provided through individual sessions, VMMC services 8 9 365 are better received when group counseling sessions are provided. There is thus need 10 11 12 366 to focus on differentiated service provisions depending on circumstances, even as 13 14 367 services are integrated. 15 16 17 368  In view of the male peer educators having higher chances of effectively referring 18 For peer review only 19 369 clients for VMMC, the peer education component needs to differentiate approaches 20 21 22 370 which might include pairing of female peer educators with their male counterparts. 23 24 25 371  There is a need to review and possibly abolish user fees attached to the diagnosis and 26 27 372 treatment of STIs among the adolescents and young people in need of such services. 28 29 30 373  Global standards on provision of quality health services to young people should be 31 32 33 374 adopted and client satisfaction surveys prioritized to enhance quality service 34 35 375 delivery.(17),(25) This will help contextualize peer education into service delivery 36 http://bmjopen.bmj.com/ 37 376 and help understand the reasons for non-referral and non-receipt of services. 38 39 40 41 42 43 44 on September 30, 2021 by guest.

Downloaded from 5 379 This operational study found moderate levels of referrals among clients counseled by young 6 7 380 peer educators with variation by service type. Receipt of contraception, VMMC and HTS 8 9 10 381 services was high among those referred. Factors affecting non-referral included age of client, 11 12 382 sex of peer educator and type of counseling session (individual/group) while type of setting 13 14 383 (rural/urban), age of client and sex of peer educators affected non-receipt of services. Peer 15 16 384 education service differentiation based on gender and service type may further enhance 17 18 For peer review only 19 385 uptake. There is also a need to review the output of the peer educator project with a view to 20 21 386 enhancing the quality of care provided to the adolescents and young people. 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 http://bmjopen.bmj.com/ 37 38 39 40 41 42 43 44 on September 30, 2021 by guest.

1 2 3 29 BACKGROUND 4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 6 30 Human Immunodeficiency Virus (HIV) is a major public health problem globally, with 1.8 7 8 31 million new infections and 0.94 million deaths in 2017.(1) However, global commitment and 9 10 32 sustained efforts have led to a decline in new HIV infections by 18% and AIDS-related deaths 11 12 33 by 34% since 2010. Despite this, low rates of HIV diagnosis and treatment initiation among 13 14 34 adolescents and young people continue to pose a significant challenge in the fight against 15 35 the disease.(2) 16 17 18 36 Against a global declineFor in death peer rate due review to AIDS-related only illnesses, the rate of death among 19 20 37 adolescents has been slower compared to adults, which is a concern worldwide.(2) 21 22 38 Coverage of HIV testing and access to treatment remain significantly low among young 23 24 39 people, especially in Sub-Saharan Africa.(2) Studies show low uptake of contraception, high 25 40 26 rates of sexually transmitted infections (STIs), teenage pregnancy, adolescent suicide 27 41 attempts, alcohol and drug use among this vulnerable age group.(2) Systematic reviews 28 29 42 have also reported poor uptake of Adolescent Sexual and Reproductive Health (ASRH) 30 31 43 services in different settings.(3) 32 33 34 44 Zimbabwe is one of the countries with the highest proportion of adolescents in the world, 35 45 with a quarter of the population between the ages 10-19 years.(4) These adolescents face a 36 http://bmjopen.bmj.com/ 37 46 myriad of challenges with respect to their sexual and reproductive health. Mirroring the 38 39 47 global scenario, Zimbabwe Demographic Health Survey (ZDHS) 2015 reports high fertility 40 41 48 rate among young girls (15-19 years), low coverage of HIV testing among 15-19 years old 42 43 49 (46% and 35% ever tested among boys and girls respectively) and poor knowledge about 44 on September 30, 2021 by guest. Protected copyright. 45 50 HIV prevention methods.(5) This increases the vulnerability of adolescents to acquire HIV 46 51 which is also highlighted in the National ASRH Strategy II: 2016-2020.(6) 47 48 49 52 To address these gaps in access and utilization of services for adolescents, the Zimbabwe 50 51 53 ASRH programme was established in 2009. The National ASRH Strategy 2016 – 2020 defines 52 53 54 an essential set of ASRH services to be delivered through four different settings: schools, 54 55 55 tertiary colleges, community and health facilities. A recent review of the ASRH program 56 56 highlighted several challenges and limitations including poor program coordination that has 57 58 57 impacted service provision and access.(7) 59 60 Page 2 of 12

1 2 3 58 The Ministry of Health and Child Care (MoHCC) also adopted voluntary medical male 4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 59 circumcision (VMMC) as an additional HIV prevention strategy in 2009 among male 6 7 60 adolescents.(8,9) The common challenges affecting the adolescents, significant overlap of 8 9 61 the interventions, as well as their mutually reinforcing nature justify the integration of 10 11 62 VMMC and ASRH programmes to maximise the reach and service provision. 12 13 63 In line with this, the MoHCC with support from the World Health Organisation (WHO) 14 15 64 commenced the pilot implementation of the VMMC - ASRH Linkages project in two 16 17 65 jurisdictions: Bulawayo city and Mount Darwin district in 2016. Various models for 18 For peer review only 19 66 integrating services were implemented in a range of settings including hospitals, clinics and 20 21 67 other health facilities, youth corners, youth-friendly centres and the community. Within this 22 68 23 project, the role of incentivized youth peer educators is integral in reaching out to the 24 69 adolescents in the community and linking them to appropriate ASRH and VMMC services in 25 26 70 designated facilities through a referral network. 27 28 29 71 Peer education has been found consistently to increase knowledge and improve attitudes 30 31 72 and intentions. Two systematic reviews have demonstrated no to moderate effect of peer 32 73 interventions in improving access to ASRH services suggesting further research. Chandra- 33 34 74 Mouli et al. in a comprehensive review, concluded that, coordinated and complementary 35 36 75 approaches are needed to improve the effectiveness of peer interventions and other ASRH http://bmjopen.bmj.com/ 37 38 76 programs.(10,11) The VMMC - ASRH linkage project is one such unique coordinated 39 40 77 approach that seeks to expand the scope of work for youth peer educators in promoting 41 42 78 SRH service uptake. 43 44 79 AIM: on September 30, 2021 by guest. Protected copyright. 45 46 47 80 In this context, we plan to conduct an operational research study to assess the role of youth 48 49 81 peer educators in uptake of sexual and reproductive health (SRH) and voluntary male 50 51 82 medical circumcision (VMMC) services among adolescents (10 – 19 years) within a pilot 52 83 linkage project setting in Zimbabwe 53 54 55 84 56 57 58 85 59 60 Page 3 of 12

Downloaded from 5 114 health facility, community, and school-based. The health facility approach required that 6 7 115 every facility establish and equip special rooms called ‘youth-friendly corners.’ The 8 9 116 community approach generally referred to ‘community youth centres (CYCs) ’, SRH drop-in 10 11 117 centers or clubs. Finally, the school-based approach is essentially the provision of life skills 12 13 118 education and counselling by both teachers and peer educators in schools. 14 119 15 16 120 The package of services included education and counselling on various topics, provision of 17 18 121 contraceptives, pregnancyFor testingpeer and management,review STI onlydiagnosis and management, post- 19 20 122 rape care, HIV testing and counselling, post-abortion care, VMMC, recreational activities, 21 22 123 referral and life and livelihood skills.(13) 23 124 24 25 125 Following this, the second National ASRH Strategy II: 2016 – 2020 was developed. This 26 27 126 strategy is based largely on comprehensive sexuality education and WHO-standard based 28 29 127 youth-friendly service provision, with a special focus on reducing new HIV infection, early 30 31 128 marriages and adolescent fertility. Under this new strategy, ASRH is a package of 32 33 129 interventions provided for those aged between 10 and 24 years delivered through schools 34 130 and colleges (primarily comprehensive sexual health education), community based activities 35 36 131 and public health facilities. The CYCs are primarily focused on recreational services by http://bmjopen.bmj.com/ 37 38 132 promoting youth development through sports, other recreational services, counselling and 39 40 133 life skills training. The adolescents are registered for ASRH services at youth centres and 41 42 134 referred to public health facilities in case they require any clinical services. 43 44 135 on September 30, 2021 by guest.

The 18 For peer review only 19 152 implementation of the project began in 2016, following a series of planning meetings and 20 21 153 development of the relevant VMMC- ASRH Linkages protocols. The project was branded 22 154 23 “Smart LyncAges Project” during the course of implementation through a participatory 24 155 process. 25 26 27 156 In Mount Darwin district, VMMC services are provided through the district hospital, whilst 28 29 157 ASRH services are being provided at Mount Darwin Hospital, Mt Darwin and Dotito CYCs. In 30 31 158 Bulawayo city, VMMC services are being provided through the Bulawayo Male Circumcision 32 159 (MC) site and the Lobengula MC site (supported by an NGO called Population Services 33 34 160 International (PSI)) and sometimes through outreach camps in the CYCs and clinics. The 35 36 161 Bulawayo City Department of Housing also runs 15 CYCs which provide basic ASRH services http://bmjopen.bmj.com/ 37 38 162 through youth officers and peer educators, whilst the City health department’s 22 clinics 39 40 163 also provide SRH services. 41 42 164 The first phase of the project had limitations in data monitoring and reporting which 43 44 165 preclude us from doing a cohort-wise monitoring of the beneficiaries. However, in the on September 30, 2021 by guest.

Under this project, the peer educators additionally received an extra day 8 9 176 to orient them on the project and their scope of work. They receive a USD 20 monthly 10 11 177 allowance. They are supposed to be holders of at least 3 ordinary level qualifications and 12 13 178 need to demonstrate ability to read and write. Each Community Youth Centre is expected to 14 179 have a minimum of 5 peer educators at any particular time. Mount Darwin has 10 peer 15 16 180 educators whilst Bulawayo city has a total of 75. They distribute condoms and provide 17 18 181 counseling on sexualFor and peer reproductive review health issues, only education, career, drug abuse, 19 20 182 relationship problems, etc. through individual and group approaches. Peer educators 21 22 183 facilitated referrals to ASRH and VMMC sites using referral slips for services like diagnosis 23 184 24 and management of STIs, HIV testing and counselling, VMMC, family planning and 25 185 management of pregnancy. Peer educators are also expected to track the referred clients 26 27 186 and in some cases accompany them to the service delivery points to ensure that they avail 28 29 187 the service. Every month, each peer educator has a target of reaching 40 adolescent clients 30 31 188 aged 10-24, two thirds being the 10-19 year olds. 32 33 189 Every peer educator maintains a ‘peer educator register’ where they document the socio- 34 35 190 demographic details of the people who received counselling. They also record whether 36 http://bmjopen.bmj.com/ 37 191 adolescents were referred and the type of services for which they were referred to. During 38 39 192 referral, the peer educator fills a client referral form in triplicate: one copy is retained with 40 41 193 the peer educator whilst the other two copies are given to the adolescent client to redeem 42 43 194 at the referral service delivery point. After the client receives the services, the service 44 195 provider at the referral centre fills details of the services provided to the client in both the on September 30, 2021 by guest.

4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 37 Objective: Peer education is an intervention within the voluntary medical male circumcision 6 7 38 (VMMC)-adolescent sexual reproductive health (ASRH) linkages project in Bulawayo and 8 9 10 39 Mount Darwin, Zimbabwe since 2016. Little is known if results extend beyond increasing 11 12 40 knowledge. We therefore assessed extent of and factors affecting referral by peer educators 13 14 41 and receipt of HIV testing services (HTS), contraception, management of sexually 15 16 42 transmitted infections (STIs) and VMMC services by young people (10–24years) counselled. 17 18 For peer review only 19 20 43 Design: A cohort study involving all young people counselled by 95 peer educators during 21 22 44 October-December 2018, through secondary analysis of routinely collected data. 23 24 25 45 Setting: All ASRH and VMMC sites in Mt Darwin and Bulawayo. 26 27 28 46 Participants: All young people counselled by 95 peer educators. 29 30 31 47 Outcome measures: Censor date for assessing receipt of services was 31 January 2019. 32 33 34 48 Factors (clients’ age, gender, marital & schooling status, counseling type, location and peer 35 36 49 educators’ age & gender) affecting non-referral and non-receipt of services (dependent http://bmjopen.bmj.com/ 37 38 50 variables) were assessed by log-binomial regression. Adjusted risk ratios (aRR) were 39 40 51 calculated. 41 42 43 44 52 on September 30, 2021 by guest. Protected copyright. 45 46 53 Results: Of the 3370 counselled (66% males), 65% were referred for at-least one service. 47 48 54 58% of males were referred for VMMC. Other services had 5-13% referrals. Non-referral for 49 50 55 HTS decreased with clients’ age(aRR:~0.9) but higher among group-counselled (aRR:1.16). 51 52 53 56 Counseling by males (aRR:0.77) and rural location(aRR:0.61) reduced risks of non-referral 54 55 57 for VMMC while age increased it(aRR≥1.59). Receipt of services was high (64-80%) except 56 57 58 for STI referrals (39%). Group-counseling and rural location(aRR:~0.52) and male peer 58 59 60 3

4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 303 This study, the first one assessing the role of the peer educators in the referral and receipt of 6 7 304 selected SRH and VMMC services among young people in Zimbabwe found relatively 8 9 10 305 moderate levels of referrals, particularly for VMMC services. A higher proportion of 11 12 306 females/girls were referred for each of the individual services as compared to males/boys. 13 14 307 However, overall more males were referred for any service compared to females likely due to 15 16 308 VMMC (for males only). However, for those referred, receipt of the services was high except 17 18 For peer review only 19 309 for STI diagnosis and treatment. Majority of the referred clients had been referred for just 20 21 310 one service, perhaps indicating limited counselling or reflecting the lack of need. The risk of 22 23 311 not being referred for HTS services decreased slightly with older age of clients, though for 24 25 26 312 VMMC services younger aged adolescents were more likely to be referred. Slightly 27 28 313 increased non-referral for HTS services was observed in clients who underwent group 29 30 314 counseling sessions as compared to individual sessions. 31 32 33 315 As regards receipt of services, generally more males received the services referred for as 34 35 36 316 compared to females. With regard to VMMC services, those counseled by male peer http://bmjopen.bmj.com/ 37 38 317 educators were more likely to be referred and to receive, likewise to the clients in the rural 39 40 318 district. Rural setting increased risk of not receiving contraception services while being 41 42 43 319 married reduced this risk. 44 on September 30, 2021 by guest. Protected copyright. 45 46 320 The low referral for diagnosis and treatment of STIs might have been influenced by: 1) lack 47 48 321 of confidence by peer educators in determining the need for referral. 2) limited self-reports of 49 50 322 STI-like symptoms. In any population, only a minority will have STI or STI - like symptoms 51 52 53 323 and referrals rates may be low. However, the low receipt of the diagnosis and treatment of 54 55 324 STIs services among the referred clients might have been due to the associated user fees 56 57 325 levied (mostly in council clinics and hospitals) in both the rural and urban settings.(17),(18) 58 59 60 15

4 327 diagnostics may improve receipt of services by young people. BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 6 7 328 Low risk perception among early adolescents has been established to be one of the barriers 8 9 329 for referral and receipt of HTS services.(19) Other studies have also shown that demand for 10 11 330 HTS services are reduced in adolescents who require parental/guardian consent, especially 12 13 14 331 due to the perceived negative reactions from parents/guardians.(19) With Zimbabwe’s age of 15 16 332 consent for HTS at 16 years, this may explain the reduced non-referral for HTS as the 17 18 333 client’s age increases.For Individualized peer or reviewclient-centered counseling only has been established to be 19 20 21 334 a more effective approach for HTS and post-test services than group counseling,(20) as 22 23 335 demonstrated also by this study. 24 25 336 26 27 28 337 Group counseling sessions may have provided an opportunity for client peer influence on 29 30 338 receipt of VMMC services. Counseling by male peer educators may also encourage openness 31 32 339 among the male clients leading to more referral and receipt of VMMC services. As regards 33 34 340 contraception, urban areas present more convenient service delivery points for accessing 35 36 http://bmjopen.bmj.com/ 37 341 contraceptives than rural areas, explaining why non-receipt is lower in the urban setups. 38 39 342 Myths on the association between modern contraception and future infertility(21),(22) may 40 41 343 have resulted in the higher non-receipt rates of contraception among the adolescent girls 42 43 44 344 referred. This belief may be more common in the rural setups and at times is propagated by on September 30, 2021 by guest.

We included all the clients who were counselled 50 51 347 by peer educators during the study period in the two project districts, which were the only 52 53 54 348 districts implementing this intervention in the whole country. As we used routine programme 55 56 349 data, the findings are likely a true reflection of the situation. The data was extracted into 57 58 350 standard proformas by the principal investigator and trained data collectors – this enhanced 59 60 16

Downloaded from 5 6 353 guidelines.(23) 7 8 9 354 Limitations: However, there were also limitations. First, due to deficiencies in 10 11 355 documentation in the peer educator registers, we could not determine if the reason for non- 12 13 14 356 referral (for VMMC or HTS) was related to ‘need’, that is, they had already received VMMC 15 16 357 or HTS services before. We, therefore couldn’t exclude clients not in need from the analysis. 17 18 358 In certain circumstances,For like peer referral for review contraception andonly STI diagnosis and treatment, we 19 20 21 359 could not perform further analyses as it was not possible to establish the appropriate 22 23 360 denominator defining the eligibility for these services. Second, we were not able to establish 24 25 361 exact reasons for non-referral and non-receipt of services. This requires qualitative and 26 27 28 362 youth-led study approaches. Third, due to small sample size of those referred for STI 29 30 363 diagnosis and treatment, we lacked statistical power to carry out further analyses. Many 31 32 364 reviews on peer education have largely focused on assessing the designs or models of peer 33 34 365 education without focusing on the outputs and the immediate positive outcomes of peer 35 36 http://bmjopen.bmj.com/ 37 366 education in relation to receipt of diagnosis and treatment of STIs, HTS, contraception and 38 39 367 VMMC services. Therefore, there were no study results to compare with. Whilst the results 40 41 368 and conclusions of this study may be used in different peer education interventions, they 42 43 44 369 cannot be generalised. on September 30, 2021 by guest.

In the long run, 13 14 380 this may also provide opportunities for home-based HTS and supervised HIV self- 15 16 381 testing. 17 18 For peer review only 19 382  While HTS services are better provided through individual sessions, VMMC services 20 21 22 383 are better received when group counseling sessions are provided. There is thus need 23 24 384 to focus on differentiated service provisions depending on circumstances, even as 25 26 385 services are integrated. 27 28 29 386  In view of the male peer educators having higher chances of effectively referring 30 31 32 387 clients for VMMC, the peer education component needs to differentiate approaches 33 34 388 which might include pairing of female peer educators with their male counterparts, to 35 36 389 enhance the acceptability, confidence and capacity of female peer educators to http://bmjopen.bmj.com/ 37 38 39 390 mobilise, counsel and refer for VMMC services. 40 41 42 391  There is a need to review and possibly abolish user fees attached to the diagnosis and 43 44 392 treatment of STIs among the adolescents and young people in need of such services. on September 30, 2021 by guest.

1 2 398 CONCLUSION 3

4 BMJ Open: first published as 10.1136/bmjopen-2019-034436 on 8 March 2020. Downloaded from 5 399 This study found varying levels of referrals ranging from 5.1% (STIs) to 58.3% (VMMC) but 6 7 400 high levels of receipt of services among referred clients. Receipt of contraception, VMMC 8 9 10 401 and HTS services was high among those referred. Factors affecting non-referral included age 11 12 402 of client, sex of peer educator and type of counseling session (individual/group) while type of 13 14 403 setting (rural/urban), age of client and sex of peer educators affected non-receipt of services. 15 16 404 Peer education service differentiation based on gender and service type may further enhance 17 18 For peer review only 19 405 uptake. Advocacy efforts for user fees removal and exemptions on SRH services for young 20 21 406 people require accelerated investment to increase service uptake. There is also a need to 22 23 407 review the output of the peer educator project with a view to enhancing the quality of care 24 25 26 408 provided to the adolescents and young people. The study also recommends qualitative 27 28 409 approaches to further understand reasons for non-referrals and non-receipt of services. 29 30 31 32 33 34 35 36 http://bmjopen.bmj.com/ 37 38 39 40 41 42 43 44 on September 30, 2021 by guest.
