What are the two main determinants of health rankings?

• A. Infant mortality and life expectancy
• B. Obesity rates and smoking
• C. Hospital readmission rates and ED visits
• D. Access to technology

Answer: (A)

Two fundamental measures used to rank population health are life expectancy and infant mortality. These outcomes capture the overall health status of a population across the lifespan and across generations. Life expectancy at birth reflects how long people are expected to live, incorporating mortality risks at all ages and the cumulative impact of health conditions, nutrition, sanitation, and access to care. Infant mortality shines a light on how well a society protects its youngest and most vulnerable, signaling the effectiveness of maternal health, infant care, and early-life conditions. Together they provide a clear, comparable snapshot of a country’s or region’s health environment, influenced by a wide range of determinants such as socioeconomic conditions, public health infrastructure, and healthcare accessibility.

Obesity rates and smoking are important risk factors that influence health, but they are behaviors rather than direct outcomes of a population’s health status. Hospital readmission rates and ED visits reflect health system performance and utilization, not the broad measure of how long people live or how many infants survive, which are the core indicators used in health rankings. Access to technology is less directly tied to overall health outcomes in ranking contexts.
