ABSTRACT
BACKGROUND
It is unknown whether subjective assessment of social status predicts health outcomes in older adults.
OBJECTIVE
To describe the relationship between subjective social status and functional decline in older adults.
DESIGN
Longitudinal cohort study.
SETTING
The Health and Retirement Study, a nationally representative survey of community-dwelling older adults (2004-2008).
PARTICIPANTS
Two thousand five hundred and twenty-three community-dwelling older adults.
MAIN MEASURES
Self-report of social status (SSS), categorized into three groups, reported by participants who marked a 10-rung ladder to represent where they stand in society. Four-year functional decline (new difficulty in any of five activities of daily living, mobility decline and/or death)
KEY RESULTS
Mean age was 64; 46% were male, 85% were white. At baseline, lower SSS was associated with being younger, unmarried, of nonwhite race/ethnicity, higher rates of chronic medical conditions and ADL impairment (P < 0.01). Over 4 years, 50% in the lowest SSS group declined in function, compared to the middle and highest groups (28% and 26%), P-trend <0.001. Those in the lowest rungs of SSS were at increased risk of 4-year functional decline (unadjusted RR = 1.91, CI 1.–9-2.46). The relationship between a subjective belief that one is worse off than others and functional decline persisted after serial adjustment for demographics, objective SES measures, and baseline health and functional status (RR 1.36, CI 1.08–1.73).
CONCLUSIONS
In older adults, the belief that one is in the lowest rungs of social status is a measure of socioeconomic distress and of significant risk for functional decline. These findings suggest that self-report of low subjective social status may give clinicians additional information about which older adults are at high risk for future functional decline.
