Temporal changes in cardiorespiratory fitness and risk of dementia incidence and mortality: a population-based prospective cohort study.

Abstract: Summary Background Cardiorespiratory fitness is associated with risk of dementia, but whether temporal changes in cardiorespiratory fitness influence the risk of dementia incidence and mortality is still unknown. We aimed to study whether change in estimated cardiorespiratory fitness over time is associated with change in risk of incident dementia, dementia-related mortality, time of onset dementia, and longevity after diagnosis in healthy men and women at baseline. Methods We linked data from the prospective Nord-Trondelag Health Study (HUNT) done in Nord-Trondelag, Norway with dementia data from the Health and Memory Study and cause of death registries (n=30 375). Included participants were apparently healthy individuals for whom data were available on estimated cardiorespiratory fitness and important confounding factors. Datasets were matched to each participant through their 11-digit personal identification number. Cardiorespiratory fitness was estimated on two occasions 10 years apart, during HUNT1 (1984–86) and HUNT2 (1995–97). HUNT2 was used as the baseline for follow-up. Participants were classified into two sex-specific estimated cardiorespiratory fitness groups according to their age (10-year categories): unfit (least fit 20% of participants) and fit (most fit 80% of participants). To assess the association between change in estimated cardiorespiratory fitness and dementia, we used four categories of change: unfit at both HUNT1 and HUNT2, unfit at HUNT1 and fit at HUNT2, fit at HUNT1 and unfit at HUNT2, fit at both HUNT1 and HUNT2. Using Cox proportional hazard analyses, we estimated adjusted hazard ratios (AHR) for dementia incidence and mortality related to temporal changes in estimated cardiorespiratory fitness. Findings During a median follow-up of 19·6 years for mortality, and 7·6 years for incidence, there were 814 dementia-related deaths, and 320 incident dementia cases. Compared with participants who were unfit at both assessments, participants who sustained high estimated cardiorespiratory fitness had a reduced risk of incident dementia (AHR 0·60, 95% CI 0·36–0·99) and a reduced risk of dementia mortality (0·56, 0·43–0·75). Participants who had an increased estimated cardiorespiratory fitness over time had a reduced risk of incident dementia (AHR 0·52, 95% CI 0·30–0·90) and dementia mortality (0·72, 0·52–0·99) when compared with those who remained unfit at both assessments. Each metabolic equivalent of task increase in estimated cardiorespiratory fitness was associated with a risk reduction of incident dementia (adjusted HR 0·84, 95% CI 0·75–0·93) and dementia mortality (0·90, 0·84–0·97). Participants who increased their estimated cardiorespiratory fitness over time gained 2·2 (95% CI 1·0–3·5) dementia-free years, and 2·7 (0·4–5·8) years of life when compared with those who remained unfit at both assessments. Interpretation Change in estimated cardiorespiratory fitness is an independent risk factor for incidence dementia and dementia mortality. Maintaining or improving cardiorespiratory fitness over time may be a target to reduce risk of dementia incidence and mortality, delay onset, and increase longevity after diagnosis. Our data highlight the importance of assessing cardiorespiratory fitness in health risk assessment for people at risk of dementia.

Time Trends in Incidence and Case Fatality of Ischemic Stroke: The Tromsø Study 1977–2010

Abstract: Background and Purpose—Ischemic stroke incidence has declined in industrialized countries the last decades, with possible exception for the youngest age groups. We estimated age- and sex-specific trends in incidence and case fatality of first-ever ischemic stroke between 1977 and 2010 in a Norwegian municipality. Methods—Age-adjusted time trends in incidence from 1977 to 2010 were estimated by fractional polynomial and Poisson regression, and case fatality by logistic regression in 36 575 participants of the population-based Tromso Study. Results—There were 1214 first-ever ischemic strokes within a total follow-up time of 611 176 person-years. The overall age- and sex-adjusted incidence decreased by 24% in 1995 to 2010. In women aged 30 to 49 years, the incidence increased significantly from 1980 to 2010. In men aged 30 to 49 years, there was a nonsignificant, rising trend from 1977 to 2010. Men aged 50 to 64 years had similar incidence in 2010 compared with 1989. From the mid-1990s to 2010, the incidence...

Inflammatory rheumatic disease and smoking are predictors of aortic inflammation: a controlled study of biopsy specimens obtained at coronary artery surgery.

Abstract: Objective Several inflammatory rheumatic diseases are associated with accelerated atherosclerosis. Atherosclerosis may result from systemic and/or local vascular inflammation. The aim of this study was to evaluate the occurrence of chronic inflammatory infiltrates in the aortas of patients with and those without inflammatory rheumatic disease who had undergone coronary artery bypass graft (CABG) surgery, and to assess the relationship between the infiltrates and other factors thought to play a role in atherosclerosis, such as smoking. Methods Aortic specimens routinely removed during CABG surgery in 66 consecutive patients with inflammatory rheumatic disease and 51 control patients without inflammatory rheumatic disease were examined by light microscopy for the occurrence, location, and severity of chronic inflammatory infiltrates and atherosclerotic lesions. Results Mononuclear cell infiltrates in the inner adventitia (apart from those localized along the epicardium) were more frequent in the group of patients with inflammatory rheumatic disease (47% versus 20%; P = 0.002, odds ratio [OR] OR 3.6, 95% confidence interval [95% CI] 1.6–8.5), and the extent of these infiltrates was greater. Multivariate analyses revealed that the occurrence of mononuclear cell infiltrates was associated with inflammatory rheumatic disease (OR 2.99, P = 0.020) and current smoking (OR 3.93, P = 0.012), and they were observed in 6 of 7 patients with a history of aortic aneurysm. Inflammatory infiltrates in the media were seen only in patients with inflammatory rheumatic disease. The frequency of atherosclerotic lesions, inflammation within the plaques, and epicardial inflammatory infiltrates in the 2 groups was equal. Conclusion Among aortic samples collected during CABG surgery, those obtained from patients with inflammatory rheumatic disease had more pronounced chronic inflammatory infiltration in the media and inner adventitia than those obtained from control patients. Current smoking was an independent predictor of chronic inner adventitial infiltrates. The infiltrates may represent an inflammatory process that promotes atherosclerosis and formation of aneurysms.

Screening for depression in elderly medical inpatients from rural area of Norway: prevalence and associated factors.

Abstract: Aim The present investigation screened for depression in order to assess the prevalence of depression and to study the associated factors with depression in elderly medically hospitalised patients from a rural area in Norway. Methods A cross-sectional study evaluated 484 (243 women) elderly medical inpatients with age range 65–101 (mean 80.7) years between September 2006 and August 2008 and used the Hospital Anxiety and Depression scale (HAD), Montgomery and Asberg Depression Rating Scale, the Mini-Mental State Examination, Lawton and Brody's scale for self-maintaining and instrumental activities of daily living. Results The prevalence of current depression, depression score ≥8 at HAD, was for the total sample 10% of whom 78% was previously not diagnosed as having depression. The odds for depression were decreased for women aged 80 years or more while for men at the same age strata it was increased threefold. Age adjusted logistic regression analyses demonstrated an increased odds for depression for those who were in need of nursing assistance before hospitalisation, had lower level of physical functioning, had clinical anxiety symptoms and had higher number of medicaments at inclusion time. Conclusion The prevalence of depression in medical hospitalised elderly from rural areas was lower than in most other hospital studies. However, most patients with depression were not previously recognised as being depressed. Copyright © 2009 John Wiley & Sons, Ltd.
