1. The cohort includes, or expects to include, incidence of the following conditions
  • Neurodegenerative disease in general
When studies on the above condition(s) are expected to become possible

Already possible

2a. Stated aim of the cohort

The Twenty-07 Study was set up in 1986 in order to investigate the reasons for differences in health by socio-economic circumstances, gender, area of residence, age, ethnic group, and family type.

2b. Features distinguishing this cohort from other population cohorts

The study consists of three cohorts born twenty years apart and each followed up for twenty years.

3a. i) Number of publications that involve use of cohort to date
3a. ii) Up to three examples of studies to date (PI, Institution, Title of Study)
3b. Publication list/link to where data or publications are accessible (if available)


3c. Information (i.e. research findings) expected to be gained from the population cohort
4a. Study criteria: age range of participants at recruitment
Age in years from:15
To (‘until death’ if applicable):55
4b. Study criteria: inclusion criteria

Living in the study area, in the community, being one of the appropriate ages, and being selected via the two stage random sampling process. ee Benzeval M, Der G, Ellaway A, Hunt K, Sweeting H, West P, Macintyre S. Cohort Profile: West of Scotland 20-07 study: health in the community. International Journal of Epidemiology 2009; 38:1215-23.

4c. Study criteria: exclusion criteria

Not living in the study area, not in the community, not being one of the appropriate ages, and not being randomly selected. ee Benzeval M, Der G, Ellaway A, Hunt K, Sweeting H, West P, Macintyre S. Cohort Profile: West of Scotland 20-07 study: health in the community. International Journal of Epidemiology 2009; 38:1215-23. At most waves, respondents with (say) severe dementia and those living in institutions would not have been interviewed. At the final wave in 2007/2008, some respondents with dementia were given a shortened or proxy interview and some in institutions were interviewed.

6b. Additional measures for participants with a clinical disorder

No, although details such as severity and medications were asked of any medical conditions reported.

6c. Are there defined primary and secondary endpoints (e.g. defined health parameters)

At each wave of the study there were questions on medical conditions. Also, respondents are flagged for mortality with the NHSCR so we have cause of death for those who have died.
