The British Women’s Heart and Health Study is a prospective cohort study of heart disease in over 4000 British women between the ages of 60 and 79. It is funded by the British Heart Foundation. The Study aims to provide information about existing patterns of treatment of heart disease, and further the understanding of risk factors and disease prevention. We collected our baseline data in 1999-2001, and have been tracking the cohort since. Participants have been re-contacted through questionnaires or assessment in 2003, 2007 & 2010.

The aim of the Cambridge Centre for Ageing and Neuroscience (Cam-CAN) project is to identify the neural mechanisms underpinning successful cognitive ageing. The study recruitment participants over 18 from resident within Cambridge City and used epidemiological, behavioural, and neuroimaging data to understand how individuals can best retain cognitive abilities into old age. A major aim of the research programme is to understand the nature of brain-cognition relationships across the lifespan, and to highlight the importance of abilities that are maintained into old age.
This population study was not designed to have repeated measures for each participant, but rather as one extended and comprehensive study visit that took place over 3 stages.
The Canberra Longitudinal Study is a 12 year study into the health and memory of older people which commenced in 1990, with subsequent waves in 1994, 1998 and 2002. The 2002 wave was the last time that participants were approached for interviews – the youngest participant in 2002 was 82 years of age.
The Costa Rican Longevity and Healthy Aging Study (CRELES) is a nationally representative longitudinal survey of health and lifecourse experiences of 2,827 Costa Ricans ages 60 and over in 2005. Baseline household interviews were conducted between November 2004 and September 2006, with 2-year follow-up interviews.
The main study objective was to determine the length and quality of life, and its contributing factors in the elderly of Costa Rica.
CRELES uses public data files containing information on a broad range of topics including self-reported physical health, psychological health, living conditions, health behaviours, health care utilization, social support, and socioeconomic status. Objective health indicators include anthropometrics, observed mobility, and biomarkers from fasting blood and overnight urine. Mortality events are tracked and conditions surrounding death are measured in a surviving family interview (longitudinal follow-up data are not yet publicly available).
For the Esprit study, 1863 non-institutionalized persons aged 65 years and over were randomly recruited in 1999 from the Montpellier district electoral rolls, and re-examined 6-times at 2-3 yearly intervals. Objectives:
1) To determine current and lifetime prevalence as well as incidence of psychiatric disorder in the elderly;
2) to determine the risk factors for these disorders, their relative weight and interactions;
3) to study clinical heterogeneity;
4) to estimate the probability of transition towards a subsyndromic state or a given pathology;
5) to elaborate predictive etiological models.
The purpose of this project is to describe changes in health and functioning among older people. Living conditions and life-style are studied as predictors of health, functioning, need of care and mortality. This multidisciplinary study includes several prospective arms. In 1988 a random sample of people aged 65-84 years were interviewed in their homes. Follow up interviews for them were conducted in 1996 and 2004. During the same years 65-69 year old people were interviewed to capture cohort changes in aging. In 1989 all men born before 1924 and every other woman living in nursing home were interviewed. In 1989 all 75-year-old and 1990 all 80-year-old residents of Jyväskylä were studied in the laboratory with extensive functional testing and clinical examinations. The 75-year-old people were followed up after 5, 10 and 15 years and the 80-year-olds after 5 and 10 years. In addition, register-based data on hospital and long-term care is being updated until the entire cohort becomes extinct. Altogether, 2500 have participated in these studies.
The main objective of the FINGER study is to find out if a multi-domain intervention could prevent cognitive decline among older people. With this intervention we also aim to investigate the effect of the multidomain intervention on disability, quality of life, depressive symptoms, the use of health care services and vascular risk factors.
Participants of the FINGER study have previously taken part in population-based non-intervention studies. They have an increased risk of cognitive decline. At the beginning of the study they are 60-77 years old. The FINGER study enrols approximately 1200 participants in six centers in Finland: Helsinki, Kuopio, Oulu, Seinäjoki, Turku and Vantaa.
The Health Survey for England series was designed to monitor trends in the nations health, to estimate the proportion of people in England who have specified health conditions, and to estimate the prevalence of risk factors associated with these conditions. The surveys provide regular information that cannot be obtained from other sources on a range of aspects concerning the publics health. The surveys have been carried out since 1994 by the Joint Health Surveys Unit of NatCen Social Research and the Research Department of Epidemiology and Public Health at UCL. Individuals are asked for written consent to link their HSE records to mortality and cancer registration data (from HSE 1994 onwards) and to Hospital Episodes Statistics (from HSE 2003 participants onwards).
Each survey in the series includes core questions and measurements (such as blood pressure, height and weight, and analysis of blood and saliva samples), as well as modules of questions on topics that vary from year to year. New topics in 2014 year included hearing and mental health. The achieved sample for the 2014 survey was 8,077 adults (aged 16 and over) and 2,003 children (aged 0-15).
i-Share (Internet-based Students HeAlth Research Enterprise) is a new open and prospective cohort on university students’ health. Participants are registered in the first years of study initially with the Universities of Bordeaux and Versailles-Saint-Quentin many many other French universities are now participating. Students are followed up with yearly assessments.
The study sets 2 main types of objectives:
1. Evaluate the frequency and impact of several diseases that may have immediate or short-term consequences on health and well-being (e.g. stress and depression, migraine, sexually transmitted infectious diseases, etc.).
2. Biomedical research objectives on the determinants of diseases. We have set up a cerebral MRI study and biobank on a sample of about 2000 participants including DNA and RNA.
The longitudinal Study of Cognitive Change in Normal Healthy Old Age (LSCC) is a population study including 6,342 healthy residence of Greater Manchester and Newcastle-upon-Tyne aged from 42 to 92 in 1983. Two different batteries of cognitive tests were alternately administered biennially with additional questionnaires and Dna sample collection until 2003. The aims of the study were to:
to determine sources of variations in rates of cognitive change between individuals
to identify factors that slow or accelerate cognitive ageing and that prolong mental productivity or accelerate decline
to generate and test functional models for the processes of biological ageing, especially of ageing of the brain and the central nervous system
to test whether the neurophysiological and consequent cognitive changes differ in idiosyncratic patterns between individuals
