Mediation Analysis of a Theory-Based Culture and Age-Appropriate HIV/STI Prevention.

Few studies have investigated mediator effects of HIV prevention interventions on adolescents in sub-Saharan Africa. Herein, we report on a secondary analysis of an intervention that increased intentions to use condoms, abstain from sexual intercourse, and seek safe male circumcision among adolescents in Botswana. In a study conducted in Botswana, 806 grade 9 students from 21 public Junior Secondary Schools were randomly assigned to either the OWN THE FUTURE: Pulling Together We Will" ( PTWW) intervention group or a health promotion control group. Both conditions consisted of 12 1-h modules, with two modules delivered during each of the six sessions on six consecutive school days. The students in both groups completed confidential computer-based surveys at several time points: pre-, immediately post-, 3, 6, and 12 months post-intervention. Mediation was assessed using the product-of-coefficients approach in a generalized estimating equations (GEE) framework. The analyses showed that condom use beliefs were significant mediators of the intervention effect on the intention to consistently use condoms over time. Also, negative socio-cultural beliefs, prevention beliefs, and HIV/STI knowledge were significant mediators of the intervention's effects on the intention to abstain from sex. Additionally, normative beliefs, prevention beliefs, parental negotiation, and circumcision knowledge were significant mediators of the intervention's effect on intention to seek safe male circumcision. The mediation analysis delineated a theoretical model and isolated activities that positively impact condom use, abstinence from sex, and circumcision intentions of Batswana middle school adolescents.

Contextualized theory-based predictors of intention to practice monogamy among adolescents in Botswana junior secondary schools: Results of focus group sessions and a cross-sectional study.

Culture and tradition influences behaviour. Multiple partner and concurrent relationships are made responsible for the increase of HIV infection in Sub-Saharan Africa. A contextualized "Theory of Planned Behaviour" was used to identify predictors of intention to practice monogamy. A mixed method design using qualitative data from focus groups, stories and a survey were analyzed for quantitative data. The qualitative data added to the behavioural beliefs a socio-cultural belief domain as well as attitudes, subjective norms, and perceived behavioural control predicted the intention to practice monogamy. The adolescents showed a tendency towards having more than one sexual partner. The normative beliefs and the socio cultural beliefs also predicted intentions while hedonistic belief and partner reaction did not. In contextualizing theory-based interventions, it is important to draw from stories and the langauage that circulate in a community about a given behaviour. More studies are needed on ways to combine qualitative approaches with quantitative approaches to inform the development of theory based culturally appropriate and context specific intervention strategies to reduce the risk of HIV.

Building research capacity through programme development and research implementation in resource-limited settings - the Ipabalele study protocol: observational cohort studies determining the effect of HIV on the natural history of cervical cancer in Botswana.

INTRODUCTION: The global burden of cancer continues to increase in low- and middle-income countries, particularly in sub-Saharan Africa (SSA). Botswana, a middle-income country in SSA, has the second highest prevalence of HIV worldwide and has seen an increase in human papillomavirus (HPV)-associated cervical cancer over the last decade in the setting of improved survival of HIV-infected women. There is an urgent need to understand more clearly the causes and consequences of HPV-associated cervical cancer in the setting of HIV infection. We initiated the Ipabalele ('take care of yourself' in Setswana) programme to address this need for new knowledge and to initiate long-term research programme capacity building in the region. In this manuscript, we describe the components of the programme, including three main research projects as well as a number of essential cores to support the activities of the programme. METHODS AND PROCEDURES: Our multidisciplinary approach aims to further current understanding of the problem by implementing three complementary studies aimed at identifying its molecular, behavioural and clinical determinants. Three participant cohorts were designed to represent the early, intermediate and late stages of the natural history of cervical cancer.The functional structure of the programme is coordinated through programmatic cores. These allow for integration of each of the studies within the cohorts while providing support for pilot studies led by local junior investigators. Each project of the Ipabalele programme includes a built-in capacity building component, promoting the establishment of long-lasting infrastructure for future research activities. ETHICS AND DISSEMINATION: Institutional review board approvals were granted by the University of Pennsylvania, University of Botswana and Ministry of Health and wellness of Botswana. Results will be disseminated via the participating institutions and with the help of the Community Advisory Committee, the project's Botswana advisory group.
