What Role Does Life Expectancy Play in Epidemiological Studies?
Life expectancy is a fundamental measure in epidemiological studies as it reflects the overall health status of a population. Higher life expectancy is generally associated with better healthcare, nutrition, and living conditions. However, it also means that more people are living into older age, thereby increasing the burden of age-related diseases. Epidemiologists use life expectancy data to predict future healthcare needs and to plan for the aging population.
