PQLI= (literacy rate index+infant mortality index+1 year life expectancy index) /3 Internationally, the main indicators to measure the health level of a country's residents are life expectancy per capita, infant mortality rate and maternal mortality rate. The three major indicators of residents' health are comprehensive indicators used internationally to evaluate the health level of residents in a country or region.
Life expectancy per capita (average life expectancy): a comprehensive indicator reflecting the health status of residents and the most comprehensive health indicator for evaluating social and economic development. Evaluation index of population health status:
1, individual health and group health: the first is individual health/health, and the second is group health/health. Healthy people should have a good average level of physical development, low incidence of acute/sexually transmitted/infectious diseases, low incidence of chronic diseases/patients/diseases that seriously endanger people's health, and low death/mortality rate collected by medical education network. Studying the health status of the population is the basic task of social medicine.
2.
