Final answer:
The 3 indicators of health are life expectancy, infant mortality rate, and literacy rate, which together provide insights into the physical, mental, and social dimensions of health in a population.
Step-by-step explanation:
When asking What are the 3 INDICATORS of HEALTH?, we're delving into how the overall health status of individuals and communities can be assessed. Health can be broadly defined by three core components: physical health, mental health, and social health, as indicated by a biopsychosocial model. The OECD, UNICEF, and the World Health Organization identify essential health indicators at the population level.
Life expectancy, which represents the average age to which a person is expected to live, is a crucial indicator of health as it reflects the aggregate outcomes related to healthcare, living conditions, and social stability. A second key indicator is infant mortality rate, the rate at which infants die before reaching their first birthday, serving as a proxy for the societal and health care system effectiveness. Lastly, health can be indicated through the lens of literacy rate, signifying the percentage of people who can read and write, which often correlates with health education and a population's ability to access and use healthcare information.
Various surveys and indices, such as the Healthy Days measure and the Well-Being Index, employ these and additional questions to capture a more nuanced picture of health, including emotional well-being, healthy behaviors, and access to basic requirements for well-being.
