Aging Well? Exploring Self-Reported Quality of Life in the Older Austrian Population Based on Repeated Cross-Sectional Data.

Increase in life expectancy around the world puts aging societies with all their challenges on the Global Public Health agenda. In Austria, additional years of life gained are not spent in good health, as healthy life expectancy is far below the European average. Using repeated cross-sectional data from three waves of the Austrian Health Interview Survey (2006, 2014 and 2019), including a total of 10,056 participants aged 65 years and above, this study examined the change in self-reported quality-of-life (QoL) over time and explored associated factors. QoL, estimated by domain scores of the WHOQOL-BREF questionnaire, increased over time but decreased with age in all survey waves. Observed mean scores were significantly higher in males than in females in all QoL domains except the social domain but sex differences disappeared in most domains in the multivariable regression analyses. Instead, factors associated with significantly higher QoL scores included younger age, higher socioeconomic status, living in Western Austria and having no chronic conditions. Statistically significant observed sex differences in QoL in the older-aged Austrian population disappeared when adjusting for income and education. Strategies and measures to increase financial capabilities may have a significant impact on QoL and well-being in this age group.
