As telomere length is partly determined by the human telomerase reverse transcriptase (hTERT), we investigated the association between an hTERT polymorphism located in its promoter region ((-) (1327)T/C) and longevity in two cohorts of older adults. Participants from the Kungsholmen project (KP; n = 1,205) and the Swedish National study of Aging and Care in Kungsholmen (SNAC-K; n = 2,764) were followed for an average period of 7.5 years. The main outcomes were hazard ratios (HR) of mortality and median age at death. In both cohorts, mortality was lower in female T/T carriers, aged 75+ years in KP (HR = 0.8, 95% CI: 0.5-0.9) and 78+ years in SNAC-K (HR = 0.6, 95% CI: 0.4-0.8) compared with female C/C carriers. T/T carriers died 1.8-3 years later than the C/C carriers. This effect was not present in men, neither in SNAC-K women aged 60-72 years. The association was not modified by presence of cancer, cardiovascular diseases, number o...

Our study aimed to verify the temporal trends in disability during 1991-2010 in an older Swedish population and to estimate the associated changes in survival. Functional status in octogenarians and nonagenarians was assessed at seven occasions with intervals of 2-3 years. Sample size varied at each assessment with an average of 646 (range 212-1096). Disability was defined as difficulty in one or more of personal activities of daily living. We compared prevalence and incidence, as well as mortality, and survival associated with disability over the 20-year period. Sex-standardized prevalence of disability remained steady over time with a tendency toward a gradual decline, and a statistically significant decrease was present among nonagenarians. Sex-standardized cumulative incidence also remained steady. The proportion of people with prevalent disabili...
