Health status and quality of life: results from a national survey in a community-dwelling sample of elderly people

Abstract

Purpose: To investigate the relation between age and HRQoL indicators in a community-dwelling population aged 65 years and older.

Methods: Data were collected within a sample stratified by age (65-69; 70-74; 75-79; 80-84; 85-89; 90 years and above) and sex and randomly selected in the population records in Switzerland. The EQ-5D was used to assess HRQoL. Analyses were conducted on the entire available sample (N = 3,073) and on the subsample with no missing data in the EQ-5D (N = 2,888), considering age, gender, education and region.

Results: Results of multiple regression analyses showed different age-related patterns across the EQ-5D. The proportion of respondents reporting no problems ranged from 51 % in the 65- to 69-year age group to 20 % in the 90 years and above age group. Odds ratio (OR) for Mobility problems increased from 2.04 in the 75- to 79-year age group to 13.34 in the 90 years and above age group; OR for Usual Activities increased from 1.76 to 11.68 and from 1.55 to 2.32 for Pain/Discomfort; OR for Self-Care increased from 5.26 in the 80- to 84-year age group to 30.36 in the 90 years and above age group. Problems with Self-Care remained low, increasing from 6.22 % in the 80- to 84-year age group to 26.21 % in the oldest age group. The magnitude of the gender, region and education effects was much lower than that of age.

Conclusion: HRQoL is globally preserved in older adults in Switzerland, even if substantial impairment is reported in very old age affecting mainly functional health dimensions. Anxiety/Depression and Pain/Discomfort did not appear to be affected by age; high rates of difficulties were reported for Pain/Discomfort but not for Anxiety/Depression.
