Chapter 33: Global Health Perspectives

Globalization is characterized as an interconnected system of economic, cultural, and communication exchanges that, while fostering technological and scientific progress, often exacerbates disparities in resource access. Global health is defined as a field of study and practice that prioritizes achieving health equity and improving well-being for all people worldwide, distinguishing it from public and international health through its focus on transnational issues and interdisciplinary collaboration. The text examines the global burden of disease, utilizing metrics such as years of life lost and disability-adjusted life years to track the transition from communicable diseases to non-communicable diseases like cardiovascular conditions and diabetes, while noting the persistent threat of pandemics such as HIV/AIDS and tuberculosis. In Canada, specific challenges like the national opioid crisis illustrate how global health trends directly impact domestic public health systems. A significant portion of the discussion is dedicated to maternal, newborn, and child health, which serve as critical markers for the overall health of societies. The evolution of global health policy is traced from the landmark Declaration of Alma-Ata and the "Health for All" movement to the Millennium Development Goals and the current 17 Sustainable Development Goals, which aim to address environmental, social, and economic determinants of health. Community health nurses are encouraged to engage in global health diplomacy, working across sectors to influence foreign policy and advocate for health as a fundamental human right. Theoretical frameworks such as postcolonial feminism are introduced to help nurses critique power imbalances and Eurocentric biases in healthcare, while precision public health is presented as a modern approach using data and technology to reduce inequities. Finally, the chapter emphasizes a shift in ethical practice, moving from individualistic bioethics toward a comprehensive global health ethics focused on social justice and the protection of at-risk populations in a complex, interdependent world.
