摘要：

Background: The primary objective of the present study was to evaluate the validity of the Groningen frailty Indicator (GFI) in a sample of Dutch elderly persons participating in LifeLines, a large population-based cohort study. Additional aims were to assess differences between frail and non-frail elderly and examine which individual characteristics were associated with frailty. Methods: By December 2012, 5712 elderly persons were enrolled in LifeLines and complied with the inclusion criteria of the present study. Mann-Whitney U or Kruskal-Wallis tests were used to assess the variability of GFI-scores among elderly subgroups that differed in demographic characteristics, morbidity, obesity, and healthcare utilization. Within subgroups Kruskal-Wallis tests were also used to examine differences in GFI-scores across age groups. Multivariate logistic regression analyses were performed to assess associations between individual characteristics and frailty. Results: The GFI discriminated between subgroups: statistically significantly higher GFI-median scores (inter-quartile range) were found in e.g. males (1 [0-21), the oldest old (2 [1-31), in elderly who were single (1 [021), with lower socio economic status (1[0-31), with increasing co-morbidity (2 [1-3]), who were obese (2 [1-31), and used more healthcare (2 [1-4]). Overall age had an independent and statistically significant association with GP scores. Compared with the non-frail, frail elderly persons experienced statistically significantly more chronic stress and more social psychological related problems. In the multivariate logistic regression model, psychological morbidity had the strongest association with frailty. Conclusion: The present study supports the construct validity of the GFI and provides an insight in the characteristics of (non)frail community-dwelling elderly persons participating in LifeLines.
