Abstract

The West of Scotland Twenty-07 Study: ‘Health in the community’ was set up in 1986 in order to investigate the reasons for differences in health by socio-economic circumstances, gender, the place where people live, age, ethnic group and family type.

The basic design of the Study involved recruiting three cohorts (groups) of volunteers, each group born twenty years apart. Members of the oldest cohort were born around 1932, those in the middle cohort were born in 1952, and those in the youngest cohort were born in 1972. A total of 4,510 people agreed to take part, and have been followed for 20 years. The final wave of data collection was completed in 2008. This means that when the Study began (1987/8) participants were 15, 35 or 55 years old, and by the end of the Study (2007/8), participants were 35, 55 and 75 years old.
The data collected are extensive and include self-reported mental and physical health (including chronic conditions, medications, disabilities); physical measures; biomarkers; cognition; life circumstances (including employment, housing, family); health behaviours; beliefs, attitudes and values. The cohort is being followed up for mortality using linkage to national records. Any data on neurodegenerative disease are from self-reported health and / or death certificates.
