The Glostrup Population Studies are population-based cohort studies performed in the western part of Greater Copenhagen, Denmark, since 1964. The studies are health examination studies with clinical and biochemical data and data from questionnaires and interviews. In 1976, the 1936 cohort was initiated with a sample of individuals born in 1936. A health examination focusing on cardiovascular disease (CVD) risk factors and the general health of the population at the age of 40 years was conducted. In 1979 to 1982, a questionnaire follow-up was performed, and the cohort was subsequently followed up with health examinations 20 years after baseline.
