These conclusions and recommendations mainly affect five parties: researchers, intervention managers, evaluators, funders and scientific journal editors. Given the absence of a vaccine or a cure, the focus remains on preventing HIV transmission. By analysing existing data on the determinants of the complex sexual behaviour of young people and their causal pathways, and by gathering additional information, researchers should make unprecedented efforts to develop alternative and more effective interventions. Accepting the complexity of sexual behaviour of young people, also means dealing with a considerable degree of uncertainty and flexibility. Intervention development, impleme tation and evaluation are to be considered inseparable: results of effectiveness evaluations should be considered of little use if no information is provided on the intervention or its implementation and vice versa. Since the evaluation should be an integral part of the intervention, intervention managers and evaluators need to work in close collaboration, without suspicion. Donors have to accept that a complex intervention cannot be designed beforehand, but requires a process approach that maps risky behaviours, dominant predictors, causal pathways and key stakeholders. This pre-intervention research should be considered a fundamental part of the intervention and donors should be aware that effectiveness depends on this phase, hence funding should be made available. In this process, reality, and not morality, should be at the forefront: young people should be approached as responsible individuals who are able to make their own decisions and need to be made competent to ensure their choice to (not) have sexual intercourse is made autonomous, without coercion or regret and with the necessary in-depth knowl- edge of risks. This requires a change in attitudes of all stakeholders involved. A complex intervention approach also means that the intervention is monitored and can be changed during its course, resulting in the need for flexible, mixed and triangulated evaluation approaches (“combination evaluation”) and flexible funding strategies. Scientific journals have the responsibility to make innovative approaches public, even though they might not be considered most rigorous by current scientific standards, as well as allow for elaborate reports on intervention development and implementation. We are convinced this can be done if all parties remain conscious of the ultimate objective; eradicating HIV among the important and vulnerable population of young people.

This paper assesses the extent to which HIV prevention interventions for young people in sub-Saharan Africa are grounded in theory and if theory-based interventions are more effective. Three databases were searched for evaluation studies of HIV prevention interventions for youth. Additional articles were identified on websites of international organisations and through searching references. 34 interventions were included; 25 mentioned the use of theory. Social Cognitive Theory was most prominent (n=13), followed by Health Belief Model (n=7), and Theory of Reasoned Action/Planned Behaviour (n=6). These cognitive behavioural theories assume that cognitions drive sexual behaviour. Reporting on choice and use of theory was low. Only three articles provided information about why a particular theory was selected. Interventions used theory to inform content (n=13), for evaluation purposes (n=4) or both (n=7). No patterns of differential effectiveness could be detected between studies using and not using theory, or according to whether a theory informed content, and/or evaluation. We discuss characteristics of the theories that might account for the limited effectiveness observed, including overreliance on cognitions that likely vary according to type of sexual behaviour and other personal factors, inadequately address interpersonal factors, and failure to account for contextual factors.

PurposeThe increased awareness of global environmental threats like climate change has created an upsurge of interest in low embodied carbon building materials for green building delivery. Though the literature advocates for the use of hemp-based building materials, there is no evidence of studies to explore its potential use in Ghana. Therefore, this study explores the potential factors that limit the adoption of hemp as an alternative sustainable material for green building delivery in Ghana.Design/methodology/approachA structured questionnaire was used to solicit the views of built environment professionals operating in construction, consulting and developer firms. The questions were developed through a comparative review of the related literature and complemented with a pilot review. Data were analysed via descriptive and inferential statistics.FindingsOn the average, the majority of the respondents showed a moderate level of awareness of hemp and its related uses in the construction industry. Also, certain key factors like the perceived association of hemp with marijuana, lack of expertise in the production of hemp-related building materials, farmers not getting the needed clearance for the cultivation of hemp, lack of legislation by the government in the legalisation of hemp and the inadequate knowledge of consumers on the benefits of hemp-based building materials were identified as potential limitations to the adoption of hemp as an alternative sustainable material for green building delivery.Originality/valueThe findings from this study provide insights into a less investigated area in sub-Saharan Africa and further provide new and additional information to the current state-of-the-art on the potential for the use of hemp in the building construction sector.

Abstract Background In sub-Saharan Africa HIV transmission is a major challenge in adolescents, especially among girls and those living in urban settings. Major international efforts have aimed at reducing sexual transmission. This analysis aims to assess the trends in HIV prevalence by gender in adolescents, as well as urban-rural disparities. Methods HIV prevalence data were obtained for 30 countries with a national survey since 2010 and for 23 countries with one survey circa 2005 and a recent survey circa 2015. Countries were grouped into 2% or higher and lower than 2% HIV prevalence among girls 15–19 years in the first survey. Country medians and average annual rates of changes were used to summarize the trends. Data on HIV incidence at ages 15–24 and prevalence at 5–9 and 10–14 years were reviewed from 11 recent national surveys. Trends in urban-rural disparities in HIV prevalence and selected indicators of sexual and HIV testing behaviours were assessed for females and males 15–24 years, using the same surveys. Results HIV prevalence among girls 15–19 years declined in the higher HIV prevalence group from 5.7–2.6% during 2005–2015, corresponding with an average annual rate of reduction of 6.5% per year. Among boys, the median HIV prevalence declined from 2.1–1.2% in the higher prevalence group. Smaller changes were observed in the lower prevalence country group where median HIV prevalence among girls decreased from 0.7–0.4% (average annual rate of reduction 5.9%). Girl – boy differences at 10–14 years were small with a country median HIV of 1.0% and 1.3%, respectively. Urban females and males 15–24 had at least 1.5 times higher HIV prevalence than their rural counterparts, and all experienced similar declines during 2005–2015. Condom use and HIV testing increased among adolescents in both higher and lower prevalence countries, but indicators of sexual activity showed little change over time. Conclusions HIV prevalence declined in almost all countries during the last decade, in both urban and rural settings, for both sexes. The urban-rural gap persisted and HIV transmission to girls, but not boys, is still a major challenge in eastern and southern African countries.
