Public policies can significantly affect health outcomes by shaping the social determinants of health. Policies related to housing, education, employment, and healthcare access have profound implications for public health. For example, policies that promote affordable housing can reduce exposure to environmental hazards, while education policies that increase access to quality education can improve health literacy and health behaviors. Epidemiologists often collaborate with policymakers to design and evaluate policies that promote health equity and address the root causes of health disparities.
