Shared Components of Worldwide Successful Sexuality Education Interventions for Adolescents: A Systematic Review of Randomized Trials

A crucial aspect of human development is sexuality which has implications for health, particularly in adolescence, since unfavorable sexual experiences may result in physical and mental problems. Sexuality education interventions (SEI) are one of the most used actions to promote sexual health in adolescents. Nevertheless, there is variability across their components; therefore, key elements for an effective SEI targeted at adolescents (A-SEI) are not well known. Based on this background, this study aims to identify the shared components of successful A-SEI through a systematic review of randomized controlled trials (RCT). This study followed the preferred reporting items for systematic reviews and meta-analyses statement. A search was conducted in CINAHL, PsycInfo, PubMed, and Web of Science between November and December 2021. A total of 21 studies passed the inclusion test after the review of 8318 reports. A total of 18 A-SEIs were identified in these studies. The components analyzed were the intervention's approach, dose, type of intervention, theoretical framework, facilitators' training, and intervention methodology. The results established that components that should be present in the design of an effective A-SEI are behavior change theoretical models, the use of participatory methodology, be targeted at mixed-sex groups, facilitators' training, and at least ten hours of weekly intervention.

Adolescent health series: Adolescent neurocognitive development in Western and Sub-Saharan African contexts

The transitional period of adolescence has long been associated with physical, social and behavioural change. During this time, adolescents start to develop their own self-identity, make important life decisions and acquire the necessary skills to successfully transition to adulthood. More recently, advances in brain imaging technology have enabled increased understanding of structural and functional changes in the human brain during this developmental period, and how they relate to social, emotional, motivational and cognitive development. The ability to integrate these developing cognitive processes in increasingly complex social contexts is a key aspect of mature decision-making, which has implications for adolescent health, educational, economic and social outcomes. Insights from the field of developmental cognitive neuroscience could increase our understanding of this influential stage of life and thus inform potential interventions to promote adolescent health, a critical goal for global health research. Many social changes occur during adolescence and the social environment shapes both brain and cognitive development and the decisions adolescents make. Thus, it is important to study adolescent neurocognitive development in socio-cultural context. Yet, despite evidence from Western studies that socio-cultural and economic factors impact on adolescent neurocognitive development, existing studies of adolescent neurocognitive development in sub-Saharan Africa are relatively scarce. We summarise research findings from Western and sub-Saharan African contexts and highlight areas where research is lacking. Longitudinal studies from more diverse global samples will be needed to build a comprehensive model of adolescent development, that characterises both commonalities in developmental trajectories, as well as the way these can meaningfully differ between both individuals and contexts.

Social and Behavioral Correlates of Adolescent Sexual Experience and Intention to Use Condoms in Northwestern Botswana

Adolescent sexual behavior is shaped by individual, social, and structural factors that can increase HIV-risk, unwanted pregnancy, and sexually transmitted disease. To inform the development of a comprehensive sexuality education program, 239 secondary school adolescents ages 14–19 in Maun, Botswana, completed a survey of sexual and reproductive health knowledge, attitudes, and behaviors in February–March 2020. Bivariate and multivariate analyses examined factors associated with sexual experience and perceived ability to insist on condoms. Approximately 21% of respondents reported having had sexual intercourse. More than half felt able to insist on condoms. Sources of information about human reproduction, alcohol use, attitudes about when sex is acceptable, and perceived sexual activity by one’s peers were predictive of sexual experience. Age, confidence in correct condom use, perceived acceptability of adolescent sex with condoms, and endorsement of prevailing gender norms were significantly associated with perceived ability to insist on condom use.
