The World Starts With Me: A multilevel evaluation of a comprehensive sex education programme targeting adolescents in Uganda
<p>Abstract</p> <p>Background</p> <p>This paper evaluates the effect of the World Starts With Me (WSWM), a comprehensive sex education programme in secondary schools in Uganda. The aim of the present study was to assess the effects of WSWM on socio-cognitive determinants of safe sex behaviour (delay; condom use and non-coercive sex).</p> <p>Methods</p> <p>A survey was conducted both before and immediately after the intervention among students in intervention (<it>N </it>= 853) and comparison (<it>N </it>= 1011) groups. A mixed model repeated measures analysis was performed to assess the effectiveness of the WSWM programme on the main socio-cognitive determinants of safe sex behaviour at post-test. A similar post-hoc comparison was made between schools based on completeness and fidelity of implementation of WSWM.</p> <p>Results</p> <p>Significant positive effects of WSMW were found on beliefs regarding what could or could not prevent pregnancy, the perceived social norm towards delaying sexual intercourse, and the intention to delay sexual intercourse. Furthermore, significant positive effects of WSWM were found on attitudes, self-efficacy and intention towards condom use and on self-efficacy in dealing with sexual violence (pressure and force for unwanted sex). A reversed effect of intervention was found on knowledge scores relating to non-causes of HIV (petting, fondling and deep kissing). A follow-up comparison between intervention schools based on completeness of the programme implementation revealed that almost all significant positive effects disappeared for those schools that only implemented up to 7 out of 14 lessons. Another follow-up analysis on the basis of implementation fidelity showed that schools with a "partial" fidelity score yielded more significant positive effects than schools with a "full" fidelity of implementation score.</p> <p>Conclusions</p> <p>The study showed an intervention effect on a number of socio-cognitive determinants. However, the effectiveness of WSWM could be improved by giving more systematic attention to the context in which such a programme is to be implemented. Implications for the systematic development and implementation of school-based safe sex interventions in Uganda will be discussed.</p
Evaluation of a school-based HIV prevention intervention among Yemeni adolescents
<p>Abstract</p> <p>Background</p> <p>This article describes an evaluation of a school-based peer education intervention for HIV prevention among students in twenty seven high schools in Aden, Yemen. The intervention was developed after a survey among the same population in 2005, which revealed a high level of stigma towards people living with HIV (PLWH) and a low level of HIV knowledge.</p> <p>Methods</p> <p>In a quasi-experimental design students who received the peer education intervention (78.6%) were compared with students who did not receive the intervention (21.4%). No systematic procedure was applied in selecting students for the intervention condition. Data were collected using a self-administered questionnaire from a sample of 2510 students from all 27 high-schools in Aden governorate. To increase internal validity, students were also compared with a cohort control sample surveyed in 2005, which was a random sample of 2274 students from the same schools.</p> <p>Results</p> <p>Sixty eight percent of students targeted by peer education had good knowledge scores, compared with 43.3% of students not targeted by peer education (Ď<sup>2 </sup>= (df = 1) = 111.15, p < .01). Multi-level regression analysis revealed that, although there was a significant difference among schools, the intervention effect of peer education at the individual level was significant; students who received peer education had a statistically higher knowledge score(9.24 out of 12.0) compared with those not targeted (7.89 out of 12.0), OR = 2.11, 95% CI = 1.04-4.27, p < .05). Compared with the 2005 cohort control sample, students targeted by peer education had better knowledge on the modes of transmission and prevention and fewer misconceptions; and knowledge on the use of condoms increased from 49.4% to 67.8%. In addition, students who received the peer education interventions suggested significantly more actions to provide care and support for PLWH. Also, the levels of stigma and discrimination were much higher among the 2005 cohort control group, compared with those who received the peer education intervention.</p> <p>Conclusion</p> <p>The school-based peer education intervention has succeeded in improving levels of knowledge on modes of transmission and prevention, and in decreasing levels of stigma and discrimination in a culturally conservative setting.</p
Tailoring intervention procedures to routine primary health care practice; an ethnographic process evaluation
Background. Tailor-made approaches enable the uptake of interventions as they are seen as a way to overcome the incompatibility of general interventions with local knowledge about the organisation of routine medical practice and the relationship between the patients and the professionals in practice. Our case is the Quattro project which is a prevention programme for cardiovascular diseases in high-risk patients in primary health care centres in deprived neighbourhoods. This programme was implemented as a pragmatic trial and foresaw the importance of local knowledge in primary health care and internal, or locally made, guidelines. The aim of this paper is to show how this prevention programme, which could be tailored to routine care, was implemented in primary care. Methods. An ethnographic design was used for this study. We observed and interviewed the researchers and the practice nurses. All the research documents, observations and transcribed interviews were analysed thematically. Results. Our ethnographic process evaluation showed that the opportunity of tailoring intervention procedures to routine care in a pragmatic trial setting did not result in a well-organised and well-implemented prevention programme. In fact, the lack of standard protocols hindered the implementation of the intervention. Although it was not the purpose of this trial, a guideline was developed. Despite the fact that the developed guideline functioned as a tool, it did not result in the intervention being organised accordingly. However, the guideline did make tailoring the intervention possible. It provided the professionals with the key or the instructions needed to achieve organisational change and transform the existing interprofessional relations. Conclusion. As tailor-made approaches are developed to enable the uptake of interventions in routine practice, they are facilitated by the brokering of tools such as guidelines. In our study, guidelines facilitated organisational change and enabled the transformation of existing interprofessional relations, and thus made tailoring possible. The attractive flexibility of pragmatic trial design in taking account of local practice variations may often be overestimated
Can the concept of Health Promoting Schools help to improve students' health knowledge and practices to combat the challenge of communicable diseases: Case study in Hong Kong?
<p>Abstract</p> <p>Background</p> <p>The growing epidemics of emerging infectious diseases has raised the importance of a setting approach and include the Health Promoting School (HPS) framework to promote better health and hygiene. Built on the concept of 'the' HPS framework, the Hong Kong Healthy Schools Award scheme includes "Personal Health Skills" as one of its key aspects to improve student hygiene knowledge and practices. This study examines the differences in student perceptions, knowledge and health behaviours between those schools that have adopted the HPS framework and those that have not adopted.</p> <p>Methods</p> <p>A cross-sectional study using multi-stage random sampling was conducted among schools with awards (HSA) and those schools not involved in the award scheme nor adopting the concept of HPS (non-HPS). For HSA group, 5 primary schools and 7 secondary schools entered the study with 510 students and 789 students sampled respectively. For the 'Non-HPS' group, 8 primary schools and 7 secondary schools entered the study with 676 students and 725 students sampled respectively. A self-administered questionnaire was used as the measuring instrument.</p> <p>Results</p> <p>Students in the HSA category were found to be better with statistical significance in personal hygiene practice, knowledge on health and hygiene, as well as access to health information. HSA schools were reported to have better school health policy, higher degrees of community participation, and better hygienic environment.</p> <p>Conclusion</p> <p>Students in schools that had adopted the HPS framework had a more positive health behaviour profile than those in non-HPS schools. Although a causal relationship is yet to be established, the HPS appears to be a viable approach for addressing communicable diseases.</p
School-based sexual health education interventions to prevent STI/HIV in sub-Saharan Africa: a systematic review and meta-analysis
Sociocognitive Predictors of Condom Use and Intentions Among Adolescents in Three Sub-Saharan Sites
Process evaluation of the teacher training for an AIDS prevention programme
This paper provides a process evaluation of a 6-day teacher training programme which forms part of a sexuality education project. The training aimed at providing teachers with the necessary knowledge and skills to effectively teach a 16-lesson Grade 8 (14 year olds) life skills curriculum consisting of participatory exercises on sexual reproductive health, human immunodeficiency virus (HIV), sexual decision-making, abstinence, consequences of sexual activity, safe sex practices, substance abuse and sexual violence. Questionnaires administered prior to the training, on completion of the training and at two follow-up time periods were analysed as well as participant observation notes. Findings indicate that teachers reported increased confidence and comfort in teaching the sexuality curriculum. However, many struggled with the transfer of sexual reproductive knowledge and facilitative teaching methods into the classroom context. This highlights the need for HIV education to form part of teacher trainee programmes. Ongoing support and engagement with teachers is needed to encourage alternative teaching practices
Characterisation of a novel UV filter in the lens of the thirteen-lined ground squirrel (Ictidomys tridecemlineatus)
Structural analysis of a novel UV filter present in the lens of the thirteen-lined ground squirrel has shown that it is related in structure to N-acetyl-3-hydroxykynurenine. This finding is consistent with the fact that the squirrel lenses also contain high levels of this tryptophan metabolite. Analysis of both NMR and mass spectrometric data suggested that the novel UV filter compound forms by condensation of proline with N-acetyl-3-hydroxykynurenine. Its absorption maximum at 340 nm is more than 20 nm lower than that of the kynurenines and it may therefore assist in filtering the more damaging shorter wavelengths of UVA
