Alberta’s Tomorrow Project (ATP) is a longitudinal study tracking the health of 55,000 adults aged 35-69 years in this western Canadian province. ATP was launched in 2000 as a prospective cohort research platform to study the relationship between environmental, lifestyle, and genetic factors and the incidence of cancer and chronic diseases.

In 2008, ATP joined a nation-wide research platform called the Canadian Partnership for Tomorrow Project (CPTP) representing more than 300,000 participants from five provincial cohorts: Alberta, British Columbia, Ontario, Quebec and the Atlantic provinces (Prince Edward Island, New Brunswick, Newfoundland and Labrador, and Nova Scotia). Together, the consortium of five regional studies provides greater statistical power for research, as well as opportunities to examine geographical trends in health and wellbeing across Canada’s vast landscape.

The information contained herein is specific to the ATP cohort.

The Sydney Centenarian Study is an ongoing project that has established a representative cohort of very elderly Australians. It has provided evidence that dementia is not inevitable at this age and that independent living is common. The data collected to date provides an excellent resource to explore the genetic and environmental factors that contribute to long life and successful cognitive aging. The study is ongoing and actively recruiting, with numerous publications in preparation.

Next Steps (previously known as the Longitudinal Study of Young People in England – LSYPE) is a major innovative cohort study of young people. The study began in 2004 and included all young people in Year 9, aged between 13 and 14, who attended state and independent schools in England.

Next Steps is one of the main information sources for the formation and appraisal of policies relating to young people and will continue to be so for at least the next 10 years. The baseline data will be used to monitor the progress of the cohort group, evaluate the success of policies aimed at this group and provide an evidence base for further policy development. The study brings together data from a wide range of sources and reflects the variety of influences on learning and progression.

Following the initial survey at age 13-14, the cohort members were visited every year until 2010, when they were age 19-20. Young people were interviewed along with their parents up to sweep 4 (age 17).

The most recent survey took place in 2015/16, when the cohort members were 25 years old. It maintained the strong focus on education, but the content was broadened to become a more multi-disciplinary research resource. Data was collected about cohort members’ housing and family life, employment and economic circumstances, education and job training, physical and emotional health, and identity and participation. A wide range of administrative data linkage consents were collected in the domains of health, education, economics and criminal behaviour.

The Wisconsin Longitudinal Study (WLS) is a longitudinal population cohort started in 1957, with a questionnaire administered to all Wisconsin High School seniors. In 1964, a randomly selected one-third of the members of the class of 1957 were followed up with a brief questionnaire to parents asking about their child’s post high-school education and occupation. Direct contact with the graduate began with a telephone interview in 1975, and subsequent telephone and mail surveys in 1993 2004. In 1977 a subset of graduate’s siblings were interviewed by phone and in 1995 and 2005 interviews were conducted with one sibling from each family whenever possible. Spouses of Graduates and Siblings who were married at the time of the 2004/2005 interview were also interviewed by phone. Most recently in-person interviews with a leave-behind questionnaire were administered in 2011 to both the graduate and sibling panels. Saliva was collected from both graduate and sibling participants via a mail-effort in 2008 and during the in-person 2011 interview.

General objectives of the NuAge Study:
1. To assess changes in dietary intakes of ageing men and women (foods, energy, macronutrients, micronutrients) and longterm exposure to functional foods from a qualitative and quantitative perspective;
2. To assess the influence of longstanding and current dietary habits and evolving food choices on changes in numerous markers of physical and cognitive status, functional autonomy and social functioning;
3. To assess the impact of age-related alterations in energy metabolism (utilisation and expenditure) and body composition, on changes in numerous markers of physical and cognitive status, functional autonomy and social functioning;
4. To assess the impact of individual (biological, psychological, health, functional, behavioural) and environmental determinants on dietary intakes.

The population is comprised of 1793 healthy men and women, selected from three age groups (68ﾖ72, 73ﾖ77, 78ﾖ82) at recruitment. A total of 82.4% of the population is French speaking participants and a total of 14.3% is English speaking participants.

KORA stands for “Kooperative Gesundheitsforschung in der Region Augsburg” (Cooperative Health Research in the Augsburg Region). KORA studies are conducted at regular intervals in order to assess the health status of the population in Augsburg and the surrounding area since 1984. The extensive database and biological specimen repository provide an excellent platform for national and international health research. More than 200 research projects a year are conducted with regional, national and international partners. To date, more than 2,000 publications have been issued. The main research areas are:
– Lifestyle and environmental factors as risk factors in the development of chronic diseases
– Identifying new genes for the most important chronic diseases and related risk factors
– Integrating research into risk factors and functional genomics
– Research on health systems: usage, costs and health status

The Australian Longitudinal Study of Ageing (ALSA) is the centrepiece research activity of the Flinders Centre for Ageing Studies. The ALSA commenced in 1992 with 2087 participants aged 65 years or more. At Baseline, a comprehensive personal interview and assessment of neuropsychological and physiological functions was undertaken at each person’s home, supplemented by self-completed questionnaires, biochemistry, and additional clinical studies of physical function. The final wave (Wave 13) of data collection was carried out in 2014.

The general purpose of the ALSA study is to gain further understanding of how social, biomedical and environmental factors are associated with age related changes in health and well-being of persons aged 70 years and over. Emphasis is given in the overall study to defining and exploring the concept of healthy, active ageing, particularly in a South Australian context.

The original aim of the Metropolit cohort was to follow men from early school age to early mid-life, to explore intergenerational mobility and differential life-chances. In 2001 the cohort was revitalised in order to study the development of chronic diseases in a life course perspective.
The Metropolit cohort comprises all 11532 men born in 1953 in the Copenhagen Metropolitan area who were living in Denmark in 1968. These men have been followed repeatedly since their birth. In brief, we have data from birth certificates (1953) which include information on birth dimensions and father’s occupation. In 1965, 7,987 participated in a school-based survey and completed tests of cognition and enquiries regarding leisure-time activities and social aspirations. Data from draft board examinations at around age 19 have been collected for 11,108 of the men. These data include cognitive testing and health information. In 2004, 6,292 of the men responded to a mailed questionnaire with questions on health and lifestyle. In 2009-2010, 2486 of 7799 eligible cohort members participated in the Copenhagen Ageing Midlife Biobank (CAMB) study which comprised questionnaires, cognitive and physical testing as well as blood sampling. Further, around 300 men selected on their young adult and current cognitive performance have been through a neurophysiological examination including EEG, MRI, fMRI and sleep tests. The cohort has also been followed in nation-wide social and health registers for social life, medical and mental hospital diagnosis as well as cause of death from 1969 to 2016.

The Lc65+ project is a longitudinal population-based study focusing on the development of frailty after the age of 65. The main methods in the Lc65+ study are:

ﾕ long term observation of subjects, beginning at 65 to 70 years, an age when frailty is still unusual, in order to study its initiation and development;
ﾕ prospective data collection on a large range of health dimensions, including psycho-social characteristics, in order to investigate the temporal sequence linking frailty, its risk factors, modulators, and outcomes:
ﾕ a population approach considering frailty as a central parameter of health in ageing populations that is useful not only for surveillance, but also for the evaluation of preventive interventions.

Follow-up is based on a yearly questionnaire sent by mail to the participant’s home. In addition, subjects are invited to the study center every three years for an interview and examination similar to those performed at baseline. The follow-up is unlimited in time and is not interrupted in the case of nursing home admission.

The Older Australian Twins Study is a longitudinal, multi-centre study that investigates healthy brain ageing in older twins (65+ years). OATS commenced in New South Wales in January 2007, in Queensland in December 2007, and in Victoria in February 2008. Since the OATS study started we have followed our twin volunteers up every two years to check on their psychological and physical health. Participants undergo rigorous medical and cognitive function tests, with many participants’ also providing bloods samples and having a magnetic resonance imaging (MRI) scan of their brain. In 2015 we finished our 4-year follow ups. OATS assessed 623 participants at baseline, 450 at the 2-year follow up, and 389 completed their 4-year follow-up.
