At the end of 2016, there were approximately 36.7 million people living with HIV worldwide with 1.6 million people being newly infected. In the same year, 1 million people died from HIV-related causes globally. The vast prevalence of HIV calls for an urgent need to develop and implement prevention programs aimed at reducing risk behaviors. Bronfenbrenner’s socio-ecological model provides an organizing framework to discuss HIV prevention interventions implemented at the individual, relational, community, and societal level. Historically, many interventions in the field of public health have targeted the individual level. Individual-level interventions promote behavior change by enhancing HIV knowledge, attitudes, and beliefs and by motivating the adoption of preventative behaviors. Relational-level interventions focus on behavior change by using peers, partners, or family members to encourage HIV-preventative practices. At the community-level, prevention interventions aim to reduce HIV vulnerability by changing HIV-risk behaviors within schools, workplaces, or neighborhoods. Lastly, societal interventions attempt to change policies and laws to enable HIV-preventative practices. While previous interventions implemented in each of these domains have proven to be effective, a multipronged approach to HIV prevention is needed such that it tackles the complex interplay between the individual and their social and physical environment. Ideally, a multipronged intervention strategy would consist of interventions at different levels that complement each other to synergistically reinforce risk reduction while simultaneously creating an environment that promotes behavior change. Multilevel interventions provide a promising avenue for researchers and program developers to consider all levels of influences on an individual’s behavior and design a comprehensive HIV risk-reduction program.

Social and Gender Norms Influencing Sexual and Reproductive Health: Conceptual Approaches, Intervention Strategies, and Evidence
Shaon Lahiri, Elizabeth Costenbader, and Jeffrey B. Bingenheimer
Research in diverse fields has examined how social and gender norms, broadly defined as informal rules of acceptable behavior in a given group or society, may influence sexual and reproductive health outcomes. One set of conceptual and empirical approaches has focused on perceptions of how commonly others perform a behavior and the extent to which others support or approve of the behavior. Another set of approaches has focused on how social norms emerge from structures of gender and power that characterize the social institutions within which individuals are embedded. Interventions intended to improve sexual and reproductive health outcomes by shifting social and gender norms have been applied across a wide range of populations and settings and to a diverse set of behaviors, including female genital mutilation/cutting, the use of modern contraceptive methods, and behavioral risk reduction for HIV. Norms-based intervention strategies have been implemented at multiple socioecological levels and have taken a variety of forms, including leveraging the influence of prominent individuals, using community activities or mass media to shift attitudes, and introducing legislation or policies that facilitate the changing of social norms. Recent advances in social and gender norms scholarship include the integration of previously disparate conceptual and empirical approaches into a unified multilevel framework. Although challenges remain in measuring social and gender norms and studying their impacts on sexual and reproductive health-related behaviors across cultures, the research will continue to shape policies and programs that impact sexual and reproductive health globally.
