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 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 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 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.

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

LifeGene is a national collaborative project designed to build up a resource for research in all medical disciplines, enabling new and groundbreaking research on the relationships among heredity, environment and lifestyle. The study includes studying several hundred thousand Swedes with the aim of creating new tools to prevent, diagnose and treat our most common diseases. LifeGene constitutes a platform for a myriad of biomedical research projects. Researchers not only in biomedicine and biotechnology but also behavioral and social sciences may benefit from access to LifeGene. By combining a biological perspective with e-epidemiology, LifeGene opens up new possibilities for a greater understanding of the interplay between heredity, lifestyle and the environment as regards to our most common diseases.

The Nurses’ Health Study II (NHS II) was established by Dr. Walter Willett and colleagues in 1989 with funding from the National Institutes of Health to study oral contraceptives, diet, and lifestyle risk factors in a population younger than the original NHS cohort.

Why a new cohort of nurses?
This younger generation of nurses included women who started using oral contraceptives during adolescence and were thus maximally exposed during their early reproductive life. Several case-control studies suggesting such exposures might be associated with substantial increases in breast cancer risk provided a particularly strong justification for investment in this large cohort. Researchers also planned to collect detailed information on the types of oral contraceptives used, which was not obtained in the Nurses’ Health Study.

In addition, NHS II obtained information on physical activity and diet in adolescence and early adult life.
