Bäckman K, Joas E, Falk H, Mitnitski A, Rockwood K, Skoog I. Bäckman K, et al. J Gerontol A Biol Sci Med Sci. 2017 Jul 1;72(7):945-950. doi: 10.1093/gerona/glw160. J Gerontol A Biol Sci Med Sci. 2017. PMID: 27522060 Free PMC article.
RESULTS: Mean frailty levels were the same (x = 0.20, p = .37) in the 1901-1902 cohort as in the 1930 cohort. Although the frailty index was linked to the risk of death in both cohorts, the hazards ratio decreased from 1.67 per 0.1 increment in the frailty index for the fi …
