11.3 Community-Level Interventions

Community-level interventions tackle health issues by engaging entire populations. These approaches empower communities to take charge of their well-being through collaborative research, coalition building, and mobilization efforts.

Environmental and policy changes create healthier spaces and social norms. By modifying physical surroundings and advocating for supportive policies, these interventions address the broader factors influencing public health outcomes.

  • Policy level factors include laws, regulations, and funding priorities
