Algerian elders are living longer lives, but shorter lives free of chronic diseases: An analysis of the 2006-2019 period

INTRODUCTIONPopulation aging in Algeria dictates that the health conditions in which the elderly are expected to spend their remaining life years are examined.Chronic diseases account for a significant proportion of lost healthy years.This study aims to estimate the chronic disease-free life expectancy for Algerian elderly, analyze its evolution from 2006 to 2019, and examine disease-specific contributions to the years with chronic diseases.METHODS Chronic diseases data, from the multiple indicator cluster surveys of 2006 and 2018-2019 and national life tables, allowed us to estimate chronic disease-free life expectancy using Sullivan's method.Disease-specific contributions to the unhealthy years were estimated using the cause-deleted healthy life expectancy approach.RESULTS Although life expectancy at the age of 60 years increased by roughly a year between 2006 and 2018-2019,
