Abstract
While many Ghanaian adolescents encounter sexual and reproductive health problems, their usage of services remains low. A social learning intervention, incorporating environment, motivation, education, and self-efficacy to change behaviour, was implemented in a low-income district of northern Ghana to increase adolescent services usage. This study aimed to assess the impact of this intervention on usage of sexual and reproductive health services by young people.
Twenty-six communities were randomly allocated to (i) an intervention consisting of school-based curriculum, out-of-school outreach, community mobilisation, and health-worker training in youth-friendly health services, or (ii) comparison consisting of community mobilisation and youth-friendly health services training only. Outcome measures were usage of sexually-transmitted infections (STIs) management, HIV counselling and testing, antenatal care or perinatal services in the past year and reported service satisfaction. Data was collected, at baseline and three years after, from a cohort of 2,664 adolescents aged 15–17 at baseline.
Exposure was associated with over twice the odds of using STI services (AOR 2.47; 95%CI 1.78–3.42), 89% greater odds of using perinatal services (AOR 1.89; 95%CI 1.37–2.60) and 56% greater odds of using antenatal services (AOR 1.56; 95%CI 1.10–2.20) among participants in intervention versus comparison communities, after adjustment for baseline differences.
The addition of targeted school-based and outreach activities increased service usage by young people more than community mobilisation and training providers in youth-friendly services provision alone.

Many governments have pursued strategies to address the specific sexual and reproductive health needs of adolescents since the 1994 International Conference on Population and Development (ICPD) placed ASRH on the global policy agenda [<xref rid="pone.0125267.ref001" ref-type="bibr">1</xref>]. However, the large relative proportion of adolescents in low and middle-income countries and related high rates of HIV, unwanted pregnancy, maternal mortality and unsafe abortion indicate needs for greater improvements in service usage [<xref rid="pone.0125267.ref002" ref-type="bibr">2</xref>, <xref rid="pone.0125267.ref003" ref-type="bibr">3</xref>].

Post-ICPD, the Government of Ghana has worked to support adolescents through Adolescent Reproductive Health Policy (2000) and National HIV/AIDS and STIs Policy (2001) initiatives, while Ghanaian health services (GHS) promote youth-friendly policies [<xref rid="pone.0125267.ref012" ref-type="bibr">12</xref>]. However, evidence suggests Ghanaian adolescents still avoid SRH services, particularly due to stigma around premarital sex, while over 750,000 adolescents become pregnant annually [<xref rid="pone.0125267.ref012" ref-type="bibr">12</xref>, <xref rid="pone.0125267.ref013" ref-type="bibr">13</xref>]. Awusabo-Asare and colleagues found that 2 in 3 young women and 4 in 5 young men with STI symptoms did not seek treatment, while approximately half of unmarried sexually-active female adolescents and over one-third of sexually-active male adolescents did not use contraceptives [<xref rid="pone.0125267.ref014" ref-type="bibr">14</xref>]. Recent surveys found 5.2% female and 3.4% male adolescents reported having experienced STIs, HIV and syphilis prevalence among Ghanaian adolescents was 1.9% and 5.5% respectively, and 8% of female adolescents reported using contraceptives, while 13% of female adolescents had already given birth or were pregnant with their first child [<xref rid="pone.0125267.ref015" ref-type="bibr">15</xref>, <xref rid="pone.0125267.ref016" ref-type="bibr">16</xref>].</p><p>Northern Ghana (i.e. Northern, Upper West and Upper East regions) has poorer economic and health outcomes than the national average, as geographical, historic, and socio-cultural factors have excluded the north from much of Ghana’s economic growth [<xref rid="pone.0125267.ref017" ref-type="bibr">17</xref>]. Research in Ghana’s Upper East Region showed 32% of out-of-school adolescents experienced difficulties accessing HIV testing services [<xref rid="pone.0125267.ref018" ref-type="bibr">18</xref>]. Qualitative research found adolescents were particularly deterred from accessing health services by costs and negative provider attitudes [<xref rid="pone.0125267.ref019" ref-type="bibr">19</xref>].

A UNESCO review indicated that more than 30% of sexuality education programmes increased condom and contraceptive use [<xref rid="pone.0125267.ref039" ref-type="bibr">39</xref>]. A review of ASRH interventions in developing countries found most positively affected adolescent knowledge and attitudes, increasing health service attendance and contraceptive usage [<xref rid="pone.0125267.ref031" ref-type="bibr">31</xref>]. However, interventions varied tremendously and many were not explicitly theoretically grounded. Evaluation methods also varied and often included relatively small sample sizes and time-periods, limiting potential conclusions. Only one large-scale ASRH intervention, in rural Tanzania, was evaluated over a three-year period [<xref rid="pone.0125267.ref040" ref-type="bibr">40</xref>–<xref rid="pone.0125267.ref042" ref-type="bibr">42</xref>].</p><p>Only two well-documented evaluations of adolescent SRH interventions have been conducted in Ghana, neither in northern Ghana [<xref rid="pone.0125267.ref027" ref-type="bibr">27</xref>, <xref rid="pone.0125267.ref043" ref-type="bibr">43</xref>]. A three-month peer-education project, initiated by the Association for Reproductive and Family Health, reported significant changes in reproductive health knowledge, use of contraceptives, willingness to buy contraceptives, and self-efficacy in contraceptive usage [<xref rid="pone.0125267.ref027" ref-type="bibr">27</xref>]. Evaluation of a 12-month SRH intervention by the African Youth Alliance found young women exposed to the intervention were more likely to use modern contraceptives and condoms than those not exposed [<xref rid="pone.0125267.ref043" ref-type="bibr">43</xref>]. However, both were small and offered limited applicability for policy-makers. Thus, policy-makers determined that large-scale ASRH interventions were needed in Ghana and should be evaluated [<xref rid="pone.0125267.ref044" ref-type="bibr">44</xref>, <xref rid="pone.0125267.ref045" ref-type="bibr">45</xref>].</p><p>Responding to the need for the implementation and evaluation of ASRH interventions in Ghana, particularly in the north, the Navrongo Health Research Centre (NHRC) was commissioned to evaluate a three-year community-based ASRH intervention in Kassena-Nankana Districts (KND), northern Ghana.

Methods included one-to-one counselling sessions, group talks, and recreational activities (e.g. dramas, films, sporting events), and 41 adults were trained to support and legitimise peer-worker activities in communities.</p></list-item></list></sec><sec id="sec012"><title>Study design and sampling</title><p>The design chosen was a community-randomised trial. For study purposes, KND was divided into 26 communities with an average population of 4,500 young people each (range 861–12,392). Communities were the unit of allocation, serving as clusters randomly allocated as intervention or comparison, while analysis subjects were young people living in study communities [<xref rid="pone.0125267.ref054" ref-type="bibr">54</xref>]. After a ten-month intervention pilot in two communities, remaining communities were assigned using simple random allocation with sealed envelopes. First, communities were identified by zone and size. Second, names were sealed in opaque envelopes. Third, representatives from Ghana Education Service and the District Health Management Team drew envelopes for intervention or comparison alternately. Thus, 11 additional communities were randomly allocated to receive the intervention (i.e. all programme components), covering a population of 36,840 young people [<xref rid="pone.0125267.ref050" ref-type="bibr">50</xref>], while 13 served as comparison sites (i.e. receiving YFHS and mobilisation components only). All young people aged 10–24 years living in intervention communities were potential beneficiaries, while young people in comparison communities benefitted from community mobilisation and health-worker YFHS training.</p><p>Study outcomes were reported health service usage within the past 12 months for STI management (i.e. diagnosis, treatment), HIV counselling and testing, antenatal care, perinatal services (e.g. delivery, postnatal care), and reported satisfaction with services received—as these were considered most crucial by service providers. The exposure variable was residency in an intervention community, as all adolescents were expected to be exposed. All residents aged 15–17 in 2005 were potentially eligible for survey cohort inclusion. Participants were selected through random sampling of district compounds from the Navrongo Health and Demographic Surveillance System (NHDSS) database in 2005 and retargeted for interview in 2008. Sample size was calculated assuming an intracluster correlation coefficient of 0.10, to account for a 33% difference in between-group outcomes with a response rate of 60% at follow-up, a 1.4% design effect, 95% significance, and 90% power [<xref rid="pone.0125267.ref045" ref-type="bibr">45</xref>].</p></sec><sec id="sec013"><title>Data collection and analysis</title><p>Data was collected at baseline (2005) and endline (2008) via cohort survey. Trained interviewers, the same gender as participants, visited each sampled compound, identified eligible adolescents, obtained parental and participant consent, and interviewed in one of the three local languages (i.e. Kasem, Nankam, Buili) at convenient locations for participants. Questionnaires, developed for male and female participants based on study objectives and similar research, were piloted in two non-study communities. Data was collected on socio-demographic characteristics, and SRH knowledge, attitudes, and reported practices during the past year (e.g. sexual norms, gender-based violence, contraceptive usage, health service usage).</p><p>Data was entered, cleaned and checked for inconsistencies using Microsoft FoxPro 6.0 and analysed using Stata12.0. Primary analysis was by intention-to-treat, defined by a participant’s residence during initial community allocation in 2005, with clustering accounted for using random effects.

Thus, intervention adolescents who had 89% higher odds of attending delivery and postnatal services than comparison adolescents at endline (OR 1.89, adjusted for baseline usage; 95%CI 1.37–2.60). As with antenatal services, more young women than young men reported using peri/postnatal services at endline, though gender differences were smaller among intervention adolescents (i.e. 52% versus 48% and 62% versus 38% in intervention and comparison areas respectively).</p><p>No obvious differences in SRH service usage between intervention and comparison adolescents were found by educational participation (<xref rid="pone.0125267.t003" ref-type="table">Table 3</xref>). As numbers not attending school were very low (i.e. less than 7% of the study population), most service-users were secondary-school students. For example, in intervention areas at endline, 61% of antenatal attendees were secondary-school students compared with 32% primary students and 8% out-of-school adolescents (<xref

This study demonstrated that a school-based and peer-outreach interventions were feasible in this setting and could therefore be used for future interventions in KND [<xref rid="pone.0125267.ref062" ref-type="bibr">62</xref>–<xref rid="pone.0125267.ref064" ref-type="bibr">64</xref>].</p><p>The intervention had no significant effect on adolescent usage of HIV counselling and testing services, the relatively low usage of which may reflect generally low community usage or fears of confirming HIV status [<xref rid="pone.0125267.ref012" ref-type="bibr">12</xref>]. Stigma and discrimination could have affected adolescent services usage, as found in literature on SRH services uptake [<xref rid="pone.0125267.ref002" ref-type="bibr">2</xref>, <xref rid="pone.0125267.ref005" ref-type="bibr">5</xref>, <xref rid="pone.0125267.ref009" ref-type="bibr">9</xref>]. As Doyle <italic>et al</italic> noted in Tanzania, youth interventions integrated within intensive, community-wide risk reduction programmes may be more successful than ASRH interventions and should be evaluated [<xref rid="pone.0125267.ref065" ref-type="bibr">65</xref>]. Young men were more likely to use STI and HIV testing services than young women, suggesting perhaps they felt greater need for these services, and future health messages could emphasis the benefits to young women of knowing their status [<xref rid="pone.0125267.ref066" ref-type="bibr">66</xref>]. Young women in intervention communities used antenatal services significantly more frequently than young men, indicating additional efforts may be warranted to encourage male involvement [<xref rid="pone.0125267.ref067" ref-type="bibr">67</xref>]. Lower service usage among primary-school versus secondary-school participants was largely explainable by age. Lower usage among out-of-school participants appeared reasonable given the low proportion of out-of-school adolescents in the KND study sample.</p><p>Adolescents in intervention areas reported more satisfaction with SRH services, as similarly noted by Teijlingen and colleagues in Nepal [<xref rid="pone.0125267.ref056" ref-type="bibr">56</xref>]. Generally, young men reported more satisfaction than did young women in both intervention and comparison areas. Though total numbers of dissatisfied adolescents were small, it is important that the major service recommendation in both groups was increased drug availability. This supports the literature that programmes to increase service usage depend on the quality of services available. Findings also support research indicating adolescents may avoid SRH services where confidentiality and privacy are not guaranteed, provider attitudes are perceived as negative, or waiting times too long [<xref rid="pone.0125267.ref068" ref-type="bibr">68</xref>].</p><sec id="sec020"><title>Limitations</title><p>As the intervention consisted of four components, it was not possible in this study to determine which component or components most influenced results. Other potential limitations include loss to follow-up, recall bias and unmeasured confounding. Loss to follow-up was primarily due to migration and not being present when interviewers visited, with no major differences between intervention and comparison communities, so was unlikely to have changed study results significantly. Recall bias may have underestimated some service usage, as participants were asked to recall usage over a twelve-month period. While some unmeasured confounding is possible in any large study, this was expected to be similar in both groups [<xref rid="pone.0125267.ref069" ref-type="bibr">69</xref>–<xref rid="pone.0125267.ref071" ref-type="bibr">71</xref>]. Data collection was quantitative, so reasons for responses could not be explored. Despite limitations, demonstration of increased service usage over a three-year period by adolescents within a rural, resource-constrained, developing country context supports and contributes to the ASRH service-usage literature [<xref rid="pone.0125267.ref025" ref-type="bibr">25</xref>, <xref rid="pone.0125267.ref029" ref-type="bibr">29</xref>, <xref rid="pone.0125267.ref072" ref-type="bibr">72</xref>].</p></sec></sec><sec sec-type="conclusions" id="sec021"><title>Conclusion</title><p>Social learning approaches aim to work through changing knowledge, skills, relationships, and environmental influences [<xref rid="pone.0125267.ref051" ref-type="bibr">51</xref>, <xref rid="pone.0125267.ref052" ref-type="bibr">52</xref>], helping explain why inclusion of school and community outreach and peer-based activities was more effective than YFHS alone. To enhance adolescent usage of SRH services, health service managers in Ghana should continue developing YFHS, with additional focus on sufficient drug supply, privacy and confidentiality, staff friendliness, and convenient hours [<xref rid="pone.0125267.ref073" ref-type="bibr">73</xref>]. Recognising that ASRH and wellbeing require more than a one-dimensional health services strengthening approach, policy-makers in Ghana could further develop school and peer-based approaches that increase environmental support and adolescent self-efficacy [<xref rid="pone.0125267.ref074" ref-type="bibr">74</xref>–<xref rid="pone.0125267.ref076" ref-type="bibr">76</xref>].
