Social Capital and Structural Interventions in HIV Prevention

Social capital—understood as the resources accessed through social networks and community bonds—has emerged as a critical enabler of effective HIV prevention, treatment and care strategies. Structural interventions, which seek to modify the social, economic and legal environments that shape risk and vulnerability, complement biomedical and behavioural approaches by addressing root causes of transmission and barriers to service uptake. Together, these concepts emphasise collective capacity, solidarity and change at the community and policy levels. Social cohesion and collective efficacy can foster trust in health services, reduce stigma and discrimination, and support adherence to prevention measures such as testing, antiretroviral therapy and pre-exposure prophylaxis. At the same time, legal and policy reforms—including decriminalisation of behaviours, protection of human rights and equitable resource allocation—can dismantle structural barriers that disproportionately affect marginalised populations. Over the past decade, research has increasingly focused on combining community-driven mobilisation with structural diagnostics to tailor interventions to local contexts, using mixed-method evaluations and mathematical modelling to quantify population-level impacts. The global significance of these approaches lies in their potential to accelerate progress towards epidemic control through sustainable, context-sensitive solutions that extend beyond individual behaviour change.
