Mathematical modeling suggests that approximately 3.36 million new HIV infections and 386,000 AIDS deaths would be averted through 2025 if 80% coverage with VMMC is achieved within five years in 13 Eastern and Southern Africa priority countries <xref rid="pone.0083642-Hankins1" ref-type="bibr">[6]</xref>. In order to achieve this level of coverage, an estimated 20.3 million VMMC procedures among men age 15 to 49 would need to be performed; an estimated 3.2 million of which had been conducted by December 2012 <xref rid="pone.0083642-Joint1" ref-type="bibr">[7]</xref>. Despite several initiatives to increase VMMC coverage in these 13 settings, the progress has been modest. While there are still service supply constraints in some areas, demand creation and uptake of services is a well-recognized barrier to achieving VMMC targets.</p><p>In order to reach 20.3 million with VMMC service, these barriers must be understood, prioritized and addressed as part of an efficient and effective VMMC program. VMMC programs in many countries have adopted a model of service provision whereby services are provided not only in fixed health facilities, but also in outreach sites and mobile units. In addition to diversifying the type of service outlets, attempts to increase circumcision through periods of high intensity and campaign approaches have also been utilized in many countries, including Tanzania and Zimbabwe. In this paper, we explored the role of these different service delivery modalities and intensity approaches in improving performance as well as attracting or preventing men of certain age from seeking and accessing VMMC services. The review specifically looks at the cases of Tanzania and Zimbabwe.</p><p>Both Tanzania and Zimbabwe are among the 13 priority countries where WHO and UNAIDS recommended that VMMC be implemented as a part of their HIV prevention programs <xref rid="pone.0083642-UNAIDS1" ref-type="bibr">[8]</xref>.</p><p><bold>In Tanzania</bold>, only one region, Iringa (which was recently divided into two administrative regional units, Iringa and Njombe), will be used for illustration and discussion in this paper. A national strategy launched in 2010 <xref rid="pone.0083642-United1" ref-type="bibr">[9]</xref> promoted scale-up of VMMC as a prevention intervention per WHO's and UNAIDS' recommendations. To scale up VMMC, Tanzania has embraced task shifting and task sharing. (Task shifting is a process of delegation: tasks are moved, where appropriate, from specialized to less specialized health care workers. Task sharing is needs-based, and uses a team approach; for VMMC it is the use of lesser-trained cadres to perform particular steps in male circumcision surgery.) By reorganizing the workforce in this way, task shifting presented a viable solution for improving coverage by more efficiently using human resources already available and quickly increasing capacity while training and retention programs are expanded <xref rid="pone.0083642-WHO1" ref-type="bibr">[10]</xref>. However, despite the use of task shifting/sharing approaches, progress was still modest and other ways of improving coverage were sought, including utilizing outreach services and limited-time campaigns for VMMC services.</p><p>The national VMMC strategy targets males between the ages of 10–34 years, who comprise 42.7% of male population (<xref ref-type="fig" rid="pone-0083642-g001">Figure 1</xref>), in regions with high HIV prevalence and low male circumcision prevalence (Iringa, Njombe, Mbeya, Rukwa, Katavi, Shinyanga, Geita, Mara, Mwanza, Tabora, Simiyu, Kagera: 12 of the 30 Tanzanian regions).

During campaigns, additional service delivery sites are identified, including health clinics at workplaces in mining and commercial farming areas as well as educational institutions, schools and universities. Demand creation is intensified during campaigns using a combination of mass media and interpersonal communications.

And they believe mobile sites are preferred to provide counseling and testing and other services if facilities are low on space. According to the informants, the decision to offer services at fixed sites during a routine or campaign schedule depends on whether the catchment area around the fixed sites had been exhausted through previous campaigns and routine service delivery. The fact that service is provided within the existing health services infrastructure, the service providers are from the public health sector and services are provided free of charge attract younger clients to easily access services. Respondents believe that older clients may prefer services that do not accept younger clients and that provide services after work hours or on weekends.

Respondents believe that the main mode of service delivery is and should be outreach because the majority of the population cannot access fixed sites. Health providers also agree with the expansion of outreach services but prefer surgical procedures to be done in facilities for infection control and therefore are only comfortable with using tents for counseling when facilities are low on space.

Moreover, there is already an underlying cultural perception that male circumcision is most appropriate before or during puberty, not in adulthood <xref rid="pone.0083642-Plotkin1" ref-type="bibr">[11]</xref>, which the respondents also discussed in this review. Campaign-based services, while increasing the number of circumcisions, seem to be an added barrier for older men; older men may avoid outreach services due to perceived lack of privacy in such high-volume settings. As shown above in <xref ref-type="fig" rid="pone-0083642-g006">Figure 6</xref>, men aged 20 and above do not utilize VMMC in similar numbers to younger men.</p><fig id="pone-0083642-g006" orientation="portrait" position="float"><object-id pub-id-type="doi">10.1371/journal.pone.0083642.g006</object-id><label>Figure 6</label><caption><title>Percentage distribution of VMMC procedures by intensity (campaign vs. routine), in Iringa and Njombe regions, Tanzania, October 2009 to December 2012.</title></caption><graphic xlink:href="pone.0083642.g006"></graphic></fig><p><bold>In Zimbabwe</bold>, cultural norms do not prescribe that circumcision should be done at a young age or during a specific season during the year, contrary to the case in Tanzania, respondents validated this belief. However, a higher proportion of younger clients access services during campaigns primarily because the campaigns are implemented during school holidays and campaign communications specifically target younger age groups and service delivery is facilitated at schools with support by head masters, teachers and parents. During routine service delivery outside of school campaigns, the program was able to attract older age groups above 25 years for VMMC. This is also supported by the finding that clients 25 years and above are not affected by the service delivery modality.</p><p><bold>In Tanzania</bold>, the age-old wisdom that adolescence is the age of peer influence might be the reason for not only the increase in the number of circumcisions performed during campaign seasons but also for the disproportionate increase in the number of adolescents in such campaigns. Resistance to peer influence is more likely to increase between the ages of 14 and 18 than at earlier ages. There is little evidence for the increase in the ability to resist peer pressure between the ages of 10 and 14 <xref rid="pone.0083642-Romer1" ref-type="bibr">[18]</xref>; therefore the client profile in Tanzania is consistent with the literature on adolescent psychosocial development in several respects. Thus, circumcision campaigns may feed on this peer pressure, in addition to the existing cultural preference for circumcision at a younger age. Conversely, older clients are not as affected by peer pressure as they are by social norms. On the other hand, once adolescents have turned their psychosocial attention toward matters of identity development, a shift that typically takes place late in adolescence and early adulthood <xref rid="pone.0083642-Romer1" ref-type="bibr">[18]</xref>, they may have developed the emotional wherewithal, as well as the need, to stand up to the influence of their peers. This may explain the situation in non-campaign routine service delivery approaches, where the majority of the clients are post-adolescent but the increase in utilization of services by this age group has not matched the increased utilization by adolescent clients during campaigns.</p><p>This is not the case <bold>in Zimbabwe</bold>, where an event such as a campaign fails to become a reason for peer pressure among adolescents only. Instead, both younger and older clients seek circumcision services when access is improved, either during campaign or non-campaign modalities. This signifies the importance of underlying cultural preferences—or the lack of preferences—on the response to programs that otherwise would attract a particular age group, as is the case in Tanzania. Zimbabwe is a country that does not traditionally circumcise men, contrary to Tanzania where most men are already circumcised and the prevalence of circumcision is higher than 80% in most regions <xref rid="pone.0083642-Hatzold1" ref-type="bibr">[17]</xref>.</p><p>The population age distribution figures (<xref ref-type="fig" rid="pone-0083642-g001">Figures 1</xref> and <xref ref-type="fig" rid="pone-0083642-g002">2</xref>) showed that the majority of the male populations in both Tanzania and Zimbabwe are under the age of 24. The difference in circumcision client profiles seen between Tanzania and Zimbabwe is difficult to attribute to one particular reason but highlights the variation in overall cultural and ethnic differences. To date, few research studies have examined socioeconomic or ethnic differences in resistance to peer influence, although there is some evidence that some communities may be more susceptible to peer pressure than others <xref rid="pone.0083642-Romer1" ref-type="bibr">[18]</xref>. In general, ethnic and socioeconomic differences in adolescents' susceptibility to peer influence have received scant attention and might be one of the causes for the difference between Tanzania and Zimbabwe that needs further investigation.</p><p>Furthermore, the programs in Tanzania and Zimbabwe were at different stages in VMMC scale-up, with proportionally much fewer sites, either fixed or outreach, in Zimbabwe than in Tanzania. It is expected that with expansion of VMMC scale-up and wider access to service delivery outlets in Zimbabwe, the proportions of males reached during routine service delivery will increase compared to the proportion reached through campaigns and with it the representation of younger clients.</p></sec><sec id="s5"><title>Conclusion</title><p>Although service delivery modality and intensity affect the profile of clients coming for services, they do so within the underlying social context, which appears particularly powerful in Tanzania, and with the programmatic approach, which appears particularly influential in Zimbabwe. Therefore, the choice of service delivery needs to take into account such underlying differences. It is important to explore not only the service delivery modality and intensity but also the underlying cultural preferences and barriers in order to effectively target older as well as younger clients and scale up VMMC services.</p><p>While, it is crucial to continue exploratory efforts to increase service utilization by older client, it is, important to note that the adolescent population represents the largest proportion of the target population for the VMMC program in Tanzania and Zimbabwe. For example, in 2010, young people aged 15–24 accounted for 42% of new HIV infections in people aged 15–49 <xref rid="pone.0083642-UNAIDS2" ref-type="bibr">[19]</xref>.
