Agreement Between Self-Reported Information and Health Register Data on Chronic Diseases in the Oldest Old.

Purpose: To study the agreement on disease prevalence between survey data and national health register data among people aged over 90.

Patients And Methods: The survey data were from the Vitality 90+ Study conducted among 1637 community dwellers and persons in long-term care aged 90 and over in Tampere, Finland. The survey was linked with two national health registers, including hospital discharge data and prescription information.

Dementia-related disability in the population aged 90 years and over: differences over time and the role of comorbidity in the vitality 90 + study.

Background: The burden of dementia, multimorbidity, and disability is high in the oldest old. However, the contribution of dementia and comorbidities to functional ability in this age group remains unclear. We examined the combined effects of dementia and comorbidities on ADL and mobility disability and differences between dementia-related disability between 2001, 2010, and 2018.

Cohort profile: The Vitality 90+ Study-a cohort study on health and living conditions of the oldest old in Tampere, Finland.

Purpose: Vitality 90+ is an ongoing population-based study with repeated cross-sectional data collections. The study was designed to examine trends in health, functioning, living conditions, quality of life and care needs among the oldest old in Finland.

Participants: Nine mailed surveys have been conducted in the city of Tampere between 1995 and 2018.

Dementia and Related Comorbidities in the Population Aged 90 and Over in the Vitality 90+ Study, Finland: Patterns and Trends From 2001 to 2018.

Objectives: To examine trends in the prevalence of dementia and related comorbidities among the oldest old.

Methods: Six repeated cross-sectional surveys were conducted between 2001 and 2018, each including all inhabitants aged over 90 in Tampere, Finland ( = 5386). Co-occurring conditions and their time trends among participants with dementia were examined using logistic regression and generalized estimating equations.

Comorbidities in dementia during the last years of life: a register study of patterns and time differences in Finland.

Background: Comorbidities have major implications for the care of people with dementia.

Aim: To investigate the patterns of comorbidities in dementia in the last five years of life and how these patterns differed between three cohorts.

Methods: The study included people who died at age 70 and above in 2001 (n = 13,717), 2007 (n = 34,750) and 2013 (n = 38,087) in Finland.

Trends of Physical Functioning, Morbidity, and Disability-Free Life Expectancy Among the Oldest Old: Six Repeated Cross-Sectional Surveys Between 2001 and 2018 in the Vitality 90+ Study.

Background: It remains unclear whether increasing longevity is accompanied by a compression or expansion of poor health and disability. We examined trends of physical functioning and morbidity in a population aged 90 and older, and disease- and disability-free life expectancy (LE) at age 90 between 2001 and 2018 in Finland's third most populated city.

Methods: We used survey data from the Vitality 90+ Study, which comprises a series of six repeated mailed surveys (7,590 observations).

Chronic conditions and multimorbidity in population aged 90 years and over: associations with mortality and long-term care admission.

Background: prevalence of many chronic conditions is rising in the aging population worldwide. However, the long-term impact of these conditions and multimorbidity on other health outcomes in very old age is rarely studied.

Methods: the data were based on four waves of the Vitality 90+ Study conducted in 2001, 2003, 2007 and 2010.
