OBJECTIVES: To determine which determinants predict frailty and domains of frailty (physical, psychological, social) in a community-dwelling sample of elderly persons.
DESIGN: Cross-sectional.
SETTING: Community-based.
PARTICIPANTS: A representative sample of 484 community-dwelling persons aged 75 years and older.
MEASUREMENTS: The Tilburg Frailty Indicator (TFI), a self-report questionnaire, was used to collect information about determinants of frailty and to assess frailty and domains of frailty (physical, psychological, social).
RESULTS: Results were obtained by regression and mediation analyses. The 10 determinants explain about 35% of the variance of frailty. After controlling for other determinants, medium income, an unhealthy lifestyle, and multimorbidity predicted frailty. The effects of other determinants differed across domains of frailty; age predicted physical frailty, life events predicted psychological frailty, whereas being a woman predicted social frailty because older women have a higher probability of living alone.
CONCLUSION: Our finding that the effect of the determinants of frailty differs across frailty domains suggests that it is essential to divide the concept of frailty into domains.
