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 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 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.

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.

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 National Child Development Study (NCDS) is a longitudinal study which follows the lives of 17,000 people born in England, Scotland and Wales in a single week of 1958. Also known as the 1958 Birth Cohort Study, it collects information on physical and educational development, economic circumstances, employment, family life, health behaviour, wellbeing, social participation and attitudes.

Since the birth survey in 1958, there have been nine further ‘sweeps’ of all cohort members at ages 7, 11, 16, 23, 33, 42, 46, 50 and 55. In 2003 (at age 45), 9,000 cohort members also participated in a special bio-medical survey to learn more about how development, environments and lifestyles affect people’s health. CLS will carry out a new survey of the NCDS cohort at age 60 in 2018.

NCDS is part of CLOSER (Cohort & Longitudinal Studies Enhancement Resources) which aims to maximise the use, value and impact of the UK’s longitudinal studies.

The primary objective of the Jackson Heart Study is to investigate the causes of cardiovascular disease (CVD) in African Americans to learn how to best prevent this group of diseases in the future.

Specific objectives include:
• Identification of factors, which influence the development, and worsening of CVD in African Americans, with an emphasis on manifestations related to high blood pressure (such as remodeling of the left ventricle of the heart, coronary artery disease, heart failure, stroke, and disorders affecting the blood vessels of the kidney).
• Building research capabilities in minority institutions at the undergraduate and graduate level by developing partnerships between minority and majority institutions and enhancing participation of minority investigators in large-scale epidemiologic studies.
• Attracting minority students to and preparing them for careers in health sciences.

The Jackson Heart Study conducted three cohort examinations, an initial clinic examination from 2000 to 2004 (Exam1), followed by a second exam from 2005 to 2008 (Exam 2) and a final exam in 2009 to 2013 (Exam 3). Starting in 2001, participants have been contacted annually, and ascertainment of hospitalizations for cardiovascular events and deaths is ongoing.

The Longitudinal Study of Generations (LSOG), initiated in 1971, began as a survey of intergenerational relations among 300 three-generation California families with grandparents (then in their sixties), middle-aged parents (then in their early forties), and grandchildren (then aged 15 to 26). The study broadened in 1991 and now includes a fourth generation, the great-grandchildren of these same families.

The study objectives were:

• To track life-course trajectories of family intergenerational solidarity and conflict over three decades of adulthood, and across successive generations of family members;
• To identify how intergenerational solidarity and conflict influence the well-being of family members throughout the adult life-course and across successive generations;
• To chart the effects of socio-historical change on families, intergenerational relationships, and individual life-course development during the past three decades;
• To examine women’s roles and relationships in multigenerational families over 30 years of rapid change in the social trajectories of women’s lives.
