Title: The health-related quality-of-life impact of chronic conditions varied with age in general population. Author: Saarni SI, Suvisaari J, Sintonen H, Koskinen S, Härkänen T, Lönnqvist J. Journal: J Clin Epidemiol; 2007 Dec; 60(12):1288-97. PubMed ID: 17998084. Abstract: OBJECTIVE: To estimate the individual- and population-level impact of major chronic conditions on health-related quality of life (HRQoL) at different ages, to test whether the HRQoL impact of conditions varies with age, and to predict future changes of quality-adjusted life years (QALYs) lost due to morbidity. STUDY DESIGN AND SETTING: HRQoL was measured using two preference-based instruments, the 15D and the EQ-5D, in a representative sample of 8,028 Finns. Information on chronic somatic conditions was obtained by interviews. Psychiatric disorders were diagnosed using a structured interview (Munich version of the Composite International Diagnostic Interview). RESULTS: The impact of chronic conditions on HRQoL increased fourfold when comparing people aged 30-44 years to people over 75 years. This was mostly due to increase in prevalence, but the severity of some conditions also varied with age. Musculoskeletal disorders had the largest and rather stable impact across ages on the population level. Psychiatric disorders placed the largest burden on HRQoL at 30-44 years, but their impact declined after 55 years. The aging of the Finnish population was predicted to increase annual QALYs lost due to morbidity by one quarter by year 2040. CONCLUSION: The impact of conditions on HRQoL varied with age for each condition.[Abstract] [Full Text] [Related] [New Search]
