Lifetime healthcare expenditures across socioeconomic groups in Sweden

Abstract

Abstract Background Individuals of lower socioeconomic status generally have higher healthcare expenditures than individuals of higher socioeconomic status. However, little is known about how expenditures are distributed across socioeconomic groups over a lifetime, once accounting for differences in life expectancy. This study describes how lifetime healthcare expenditures are distributed across age, sex and socioeconomic groups in Sweden while adjusting for differences in life expectancy. Methods Healthcare utilization from 2016 were linked to demographic and socioeconomic data for a random sample of individuals aged 20 and above in the four largest Swedish regions (n = 440 659). Mortality data were used to estimate income- and sex-specific survival rates. Expected lifetime healthcare expenditures were estimated by combining survival rates with mean healthcare expenditures over age, by sex, and income quintile. Results We find that expected lifetime healthcare expenditures are highest among the first (lowest) income quintile despite their evident lower life expectancy. Expected lifetime expenditures were 17.9% (16.8%) higher in the first income quintile compared to the fifth (highest) quintile for women (men). Individuals in the first income quintile had higher expected lifetime expenditures for all care categories except for primary care. Conclusion We conclude that despite a lower life expectancy, the quintile of the lowest socioeconomic status still had higher lifetime healthcare expenditures.
