The Southall And Brent Revisited Study (SABRE) is the largest tri-ethnic population-based cohort in the UK, involving nearly 5000 European, Indian Asian and African Caribbean men and women. It investigates the causes of diabetes and disorders of the heart and circulation and examines underlying reasons for ethnic differences in risk of these disorders.

The participants were aged 40-69 when first studied between 1989 and 1991. In 2008-2011 a comprehensive combined morbidity and mortality follow up was carried out, together with non-invasive clinical measurements in order to quantify sub-clinical disease. SABRE visit 2 tested hypotheses generated from the Southall and Brent baseline studies and ongoing mortality follow-up.

SABRE Visit 3 (25 year follow-up visit) started in July 2014 and is collecting data on index participants and new participants, including partners of index participants. The focus of this visit is on cardiac, cognitive and physical function in older age, in association with mid-life risk factors. Ethnic and gender differences in function will also be examined.

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.

Initially, the study focus was on perinatal, infant, and early childhood morbidity and mortality. We were particularly interested in breastfeeding patterns and nutritional status, as well as social and environmental factors. Deaths of cohort members were identified by regular visits to all hospitals, cemeteries, offices of civil registrations, and local health authorities, since 1982.

By mid-childhood, the study shifted in emphasis to child care, utilization of health services, selected morbidity indicators, and child development. A random sub-sample of 360 four-year-olds was selected for an in-depth study of psychomotor development.

In adolescence, issues related to sexual and reproductive behaviours (including teenage pregnancies), habits such as smoking and alcohol drinking, mental health, and education became the focus of the investigation. A sub-study investigated oral health in a random sample of 900 adolescents, and an ethnographic study of 96 cohort members, stratified by sex and socioeconomic status, has included repeated in-depth visits from the age of 15 to 30 years, aimed at understanding the role of adolescent development in influencing high-risk behaviours.

In more recent phases, with cohort members being young adults, the main emphasis has shifted to risk factors for chronic disease (including smoking, diet, physical exercise, and overweight), reproductive history, and mental health.

This is the largest multi-centre study of ageing in men in the world and intends to identify the nature and frequency of some of the symptoms of ageing in men, the relationships between these symptoms to hormonal changes and other risk factors.

In total, 3369 men in 8 different countries in Europe are taking part in the study. These 8 centres are Manchester – UK, Malmo – Sweden, Tartu – Estonia, Lodz – Poland, Szeged – Hungary, Florence – Italy, Santiago de Compostela – Spain, Leuven – Belgium. In each centre, ~400 men aged between 40 and 79 years at the start of the study have been recruited. They will be followed up to look for future changes in their hormonal and general health status. The men will be investigated initially on two occasions, at the start and then ~5 years later. It is highly likely that the study will continue beyond 5 years and further testing will be organised subsequently. The aims of the study are to:

Document geographical variations in the ageing-related involution decline of endocrine function in European men;
Explain the variability in the rate of secular decline in endocrine functions on the basis of socio-demographic, lifestyle, co-morbid, ethnic/racial, or genetic factors;
Predict the physical and psychological health status of individuals based on the variation in ageing-related endocrine decline and changes in body composition.

The Airwave Health Monitoring Study was established to evaluate possible health risks associated with the use of TETRA, a digital communication system used by the police forces and other emergency services in Great Britain since 2001. It is a long-term observational study following up the health of the police force with respect to TETRA exposure, and ability to monitor both cancer and non-cancer health outcomes. Around 53,000 participants have been recruited between 2004 and 2015.

InveCe.Ab (Invecchiamento Cerebrale ad Abbiategrasso) is a longitudinal, population-based study of disorders of brain ageing involving the assessment and long-term monitoring of the physical conditions and cognitive status. The target population comprises all Abbiategrasso residents born between 1935 and 1939, a reference sample, according to Population Register data, of around 1,700 people.

Those who agreed to participate in the Invece.Ab study were enrolled in a cross-sectional assessment and will be contacted two and four years after the initial data collection to participate in the longitudinal survey. Both the cross-sectional and longitudinal assessments include a medical evaluation, a neuropsychological test battery, several anthropometric measurements, a social and lifestyle interview, blood analyses, and the storage of a blood sample for the evaluation of putative biological markers.

The aim of the study was to determine the incidence of Parkinson’s disease and other degenerative / vascular parkinsonian disorders in a defined geographical area in the North-East of Scotland and to describe the long-term prognosis of patients and carers in an incident cohort compared to age-sex matched community controls.

Ascertainment:

Referrals from GPs
Referrals from hospital consultants
Hand-searching referral letters (neurology & DOME)
Electronic searching (GP, hospital discharge data)
Screening over 65 and over 75’s

Annual follow-up plus linked to death register.

CFAS Wales aims to interview a representative sample of 3,750 people aged 65 and over in two areas in Wales (Gwynedd and Swansea). Using established and standardised techniques it will collect data that will enable the investigation of cognitive impairment, depression, physical disability and healthy active life expectancy for the whole group and within social groups. It will provide a foundation for other collaborative studies that investigate biomarkers and other early indications of risk of cognitive decline, such as imaging. It will investigate factors that may delay the onset of dementia, specifically focussing on the role of bilingualism and social networks. As the participants reside in a bilingual area this is a key opportunity.

The original purpose of the Add Health study was to help understand the causes of adolescent health and health behaviour with special emphasis on the effects of multiple contexts of adolescent life.

The cohort was then followed through their transition to adulthood and research turned to understanding the determinants and consequences of developmental and health trajectories from adolescence into adulthood.

Add Health combines longitudinal survey data on respondents social, economic, psychological and physical well-being with contextual data on the family, neighbourhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviours in adolescence are linked to health and achievement outcomes in young adulthood. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioural, and biological linkages in health trajectories as the Add Health cohort ages through adulthood, and the fifth wave of data collection continues this biological data expansion (2016-2018).

ADNI began in October 2004. The overall goal is to validate biomarkers for Alzheimer’s disease clinical trials. One aim is to find, validate and standardize more sensitive and accurate methods to detect Alzheimer’s disease at earlier stages and mark its progress through biomarkers. The study gathered and analyzed thousands of brain scans, genetic profiles, and biomarkers in blood and cerebrospinal fluid that are used to measure the progress of disease or the effects of treatment. More information on ADNI-info.org. All data is publically available at USC/LONI/ADNI.

The three overarching longitudinal ADNI study goals are:

Validation of biomarkers, especially for amyloid and tau, for use in AD clinical trials.
To detect Alzheimer’s disease (AD) at the earliest stage possible and identify ways to track the disease through biomarkers.
To support advances in AD intervention, prevention and treatment through the application of new diagnostic methods to apply at the earliest stages technically possible – when intervention may be most effective.
To continually develop ADNI’s now- legendary data access policy and continuously improve and expand the unprecedented data sharing model.
