ULSAM is a unique, ongoing, longitudinal, epidemiologic study based on all available men, born between 1920 and 1924, in Uppsala County, Sweden. The men were investigated at the ages of 50, 60, 70, 77, 82 88 and 93 years. The reinvestigations in ULSAM were based on the previous investigations. Full screening and official registry data is available in our databases and more data is continuously added.

Health examination at 93 years of age was carried out between December 2013 and March 2015. To this examination 245 men have been invited. Totally 147 men (60%) participated in the investigation. Of these, 23 men were examined at the hospital and 102 were visited at home by a nurse. In addition, 22 men completed only a questionnaire. To this examination even spouses were invited. In the complete examination 43 spouses have participated and 11 completed only a questionnaire.

The West of Scotland Twenty-07 Study: ‘Health in the community’ was set up in 1986 in order to investigate the reasons for differences in health by socio-economic circumstances, gender, the place where people live, age, ethnic group and family type.

The basic design of the Study involved recruiting three cohorts (groups) of volunteers, each group born twenty years apart. Members of the oldest cohort were born around 1932, those in the middle cohort were born in 1952, and those in the youngest cohort were born in 1972. A total of 4,510 people agreed to take part, and have been followed for 20 years. The final wave of data collection was completed in 2008. This means that when the Study began (1987/8) participants were 15, 35 or 55 years old, and by the end of the Study (2007/8), participants were 35, 55 and 75 years old.
The data collected are extensive and include self-reported mental and physical health (including chronic conditions, medications, disabilities); physical measures; biomarkers; cognition; life circumstances (including employment, housing, family); health behaviours; beliefs, attitudes and values. The cohort is being followed up for mortality using linkage to national records. Any data on neurodegenerative disease are from self-reported health and / or death certificates.

The Concord Health and Ageing in Men Project (CHAMP) is one of the world’s largest and most comprehensive study of the health of older men ever conducted anywhere in the world. CHAMP involves 1705 men aged 70 years and older recruited from the community living near Concord Hospital in Sydney’s inner west. Subjects were recruited during 2005 and 2006 and subjects were re-assessed after two, five and nine years. A 14 year follow-up assessment (wave 5) is planned for 2019. Clinical dementia assessment was done at baseline but not in waves 2, 3, and 4. Clinical dementia assessment will be included in wave 5.

The study is particularly concerned with cognitive impairment and dementia; falls, fractures and osteoporosis; and urinary problems.

The VLS is a long-term, large-scale, and multi-faceted longitudinal investigation of human aging. Incorporating biomedical approaches, leading-edge technologies, and epidemiological perspectives, the VLS evaluates and tracks actual cognitive, health, functional and lifestyle trajectories leading to outcomes that can be classified as normal, resilient, exceptional, impaired, or dementia. Our studies examine these differential brain and cognitive changes as a function of interactions among multiple “biomarkers” of both risk and protection. Among these dynamically interacting biomarkers are those representing selected aspects of biological, health, genetic, metabolic, vascular, lifestyle, physical fitness, cognitive activity, sex/gender, and demographic domains

Korea became an ageing society in 2000, as the proportion of those 65 or older reached 7% of the population. Thereafter, the country is expected to undergo a rapid ageing process. Korea was belated compared to other advanced countries in reaching the ageing society status, but it is expected to become a super-aged society around the same time as others.

Lacking in basic data on ageing, Korea is in need of a structured set of statistical data. – Institutional reform and policy-making in preparation against the aged society require systematic build-up of data that can track individuals’ labor participation, income and asset status, spending patterns, retirement decisions, impact of social welfare, health, and intra-family transfer of income, among others.

The purpose of KLoSA is to create the basic data needed to devise and implement effective social, economic policies to address the trends that emerge in the process of population ageing.

The data will help identify and observe different dimensions of an aged society, build datasets that enable studies in different fields, and generate data comparable with similar panel studies in other countries (eg. U.S., Europe) that can provide the basis for policy-making and academic studies.

The Confucius Hometown Aging Project (CHAP) is a longitudinal study of vascular risk factors, ageing, and health in people aged 60 years or older who live in a rural community near Qufu (hometown of Confucius), Shandong, China. The study was done by local hospital staff consisting of clinicians and nurses.

The EPIPorto study is a landmark in epidemiological research in Portugal. It is a population-based cohort study, ongoing for over 15 years, with the main aim of assessing the determinants of health in the adult population of Porto. For this purpose we randomly selected 2485 persons, who have been repeatedly evaluated over time.

Participants were invited to visit the study centre to answer a questionnaire on social, demographic and behavioural characteristics, and their clinical history. Additionally, objective measurements were made, including blood tests, blood pressure, weight and height, electrocardiogram, evaluation of lung function and bone mineral density. The participants’ address was georeferenced, allowing the analysis of the spatial distribution of health states and events in the city. Subgroups of the cohort at the baseline evaluation were used as controls in case-control studies namely on myocardial infarction and gastric cancer.

JSTAR project researchers aimed to construct a world-class longitudinal dataset on middle-aged and elderly Japanese persons to enable researchers worldwide to perform scientific investigation on aging and retirement from an international perspective. Despite the rapid aging of the Japanese population, no statistical survey that could properly capture the diversity of the elderly population from various viewpoints had been carried out in Japan until recently. RIETI, Hitotsubashi University jointly launched a comprehensive survey of elderly people in 2007 to collect panel data on their lives and health, with the University of Tokyo joining from 2009 onward.
The 2009 JSTAR survey includes a follow-up survey of the respondents to the 2007 survey and an initial survey of elderly people in two additional municipalities, i.e., Tosu in Saga Prefecture and Naha in Okinawa Prefecture, whereas the 2011 JSTAR Survey includes follow-up surveys of the respondents to the 2007 and 2009 surveys plus an initial survey of elderly people in three additional municipalities, Tondabayashi, Chofu, and Hiroshima

The MemoVie cohort study aims to investigate the living conditions or risk factors under which the normal cognitive capacities of the senior population in Luxembourg (? 65?year-old) evolve (1) to mild cognitive impairment (MCI) ? transitory non-clinical stage ? and (2) to AD. Identifying MCI and AD predictors undeniably constitutes a challenge in public health in that it would allow interventions which could protect or delay the occurrence of cognitive disorders in elderly people. In addition, the MemoVie study sets out to generate hitherto unavailable data, and a comprehensive view of the elderly population in the country.

A 1-year follow-up was included in the original design of the study. The enrolled participants have been followed-up.

A family-based cohort study that is embedded in the Genetic Research in Isolated Populations (GRIP) program in the South West of the Netherlands. The aim of this program was to identify genetic risk factors in the development of complex disorders. For the ERF study, 22 families that had at least five children baptized in the community church between 1850-1900 were identified with the help of genealogical records. All living descendants of these couples and their spouses were invited to take part in the study. Data collection started in June 2002 and was finished in February 2005 (n=2065).
