The Coronary Artery Risk Development in (Young) Adults (CARDIA) Study was initiated in 1984 by the National Heart, Lung, and Blood Institute (NHLBI) to assist in providing a better understanding of the
trends and determinants of coronary heart disease (CHD) in the United States (US). The study began by focusing on young adults ? persons 18 to 30 years of age at the time of the Year 0 (Y0) baseline
screening, undertaken between March 1985 and June 1986. A random selection of 5,115 black and white men and women identified by each of the four CARDIA field centres constituted the cohort.

Follow?up examinations at Y2, Y5, Y7, Y10, Y15, Y20, and Y25 achieved high retention, collected a rich set of high quality data and stored specimens bearing on the risk factors and possible causes of cardiovascular disease (CVD).

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.

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 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.

Born in Bradford is a long term study of a population cohort of 13,500 children, born at Bradford Royal Infirmary between March 2007 and December 2010, whose health is being tracked from pregnancy through childhood and into adult life. The information collected from the BiB families is being used to find the causes of common childhood illnesses and to explore the mental and social development of this new generation.

The Born in Bradford cohort study offers a unique window of opportunity to initiate an innovative and multidisciplinary programme of research. By recruiting pregnant women, their partners and their newborn babies to the cohort, this study offers the potential to:

  • assess the determinants of childhood and adult disease
  • assess the impact of migration
  • explore the influences of pregnancy and childbirth on subsequent health
  • generate and test hypotheses that have the potential to improve health for some of the most disadvantaged within our society.

The Bradford community provides a unique setting for a birth cohort study exploring the determinants of childhood and adult disease because of its diversity of population and high levels of ill-health.

For 30 years (since 1987) tracks the health of a group of randomly selected adult Dutch inhabitants of Doetinchem from originally between 20-60 years. This provides a wealth of information of four generations: 20-29, 30-39, 40-49 and 50-60 year olds. The name of this study is the Doetinchem Cohort Study. Every five years the health and habits of the participants are examined at the local health department.

The purpose of the Doetinchem Cohort Study is to give insight into trends in lifestyle and health. So there will be more and more knowledge about why some people age without many problems, while others have health problems at an early age. The study collects data on:

  • Lifestyle habits: exercise, diet, smoking, alcohol consumption;
  • Biological factors: blood pressure, cholesterol, (over) weight;
  • Several specific diseases: cardiovascular disease, asthma, COPD , diabetes, cancer, migraine, musculoskeletal;
  • Quality of life: cognitive functioning, social participation, psychosocial aspects of health.

The Rhineland Study is a prospective cohort study, which began in March 2016. It will include up to 30,000 participants from Bonn and asses their physical and mental health over their lifespan. The study is scheduled to run for decades and participants will be re-examined every 3-4 years.

As neurodegenerative diseases and their pathologies develop over a long time before first symptoms start to show, the Rhineland Study will include men and women aged 30 years and above regardless of their health status.
The main aims of the study are:

1. To investigate modifiable and non-modifiable causes of neurodegenerative and neuropsychiatric diseases
2. To find biomarkers/(multimodal) biomarker profiles to identify individuals at risk for neurodegenerative or neuropsychiatric disease, who might benefit from preventive interventions
3. To investigate (patho)physiology over the adult life course, with specific emphasis on brain-related outcomes.

TRACK-HD was a prospective observational biomarker study in participants with premanifest and early Huntington’s disease (HD). Track-HD assessed longitudinal data collected at baseline, 12 months, 24 and 36 months at sites in Leiden (Netherlands), London (UK), Paris (France), and Vancouver (Canada). Participants were individuals without HD but carrying the mutant HTT gene (ie, premanifest HD), patients with early HD, and healthy control individuals matched by age and sex to the combined HD groups. Data were collected with 3T MRI, clinical, cognitive, quantitative motor, oculomotor, and neuropsychiatric assessments. TrackOn-HD followed on from TRACK-HD aiming to investigate compensatory mechanisms in premanifest gene carriers. Baseline, 12 and 24 month data was collected from the same four sites on premanifest gene carriers and healthy controls including 3T MRI, task and resting state fMRI, DTI, clinical, cognitive, quantitative motor and neuropsychiatric assessments.
