Public health impact research focuses on understanding the effect of interventions, policies, programs, and environmental factors on the health of populations. This research aims to assess the overall impact on public health outcomes such as disease prevalence, mortality rates, quality of life, and healthcare costs. It involves evaluating the effectiveness of various public health strategies, identifying disparities in health outcomes, and informing evidence-based decision-making to improve population health and well-being. Public health impact research often involves multidisciplinary approaches and collaboration with communities, policymakers, and healthcare providers to address public health challenges and promote health equity.
