Life expectancy free of multimorbidity among Brazilian older adults: National Health Survey, 2013

Abstract

This study aims to analyze differences in life expectancy with and without multimorbidity (two or more chronic conditions) among older adults in Brazilian states, according to sex and age. Data from the Mortality Information System and population projections from the Brazilian Bureau of Geography and Statistics were used to create life tables for all states by sex. Information on the prevalence of multimorbidity was obtained from the 2013 National Health Survey (PNS). The Sullivan method was used to estimate life expectancy with and without multimorbidity and the proportion of expected life years with multimorbidity. The sample of older adults in the PNS included 11,697 subjects whose mean age was 70.08 years (SD ± 0.09). The proportion of expected years with multimorbidity increases with age (53.6% at age 60, and 57.3% at age 75). Women have higher life expectancy than men, but they live with multimorbidity more years. At age 60, Brazilian women expect to live, on average, 13.5 years with multimorbidity and men 8.3 years. There are major differences in life expectancy with multimorbidity across states – varying from 8.2 to 14.2 years (at age 60). It is important to consider these differences when defining priorities for public policies and public health interventions.
