Dataset: Danish Work Environment Cohort Study

Abstract

The Danish Work Environment Cohort Study (DWECS) uses a split panel design: The 1990 panel consists of a simple random sample drawn in 1990 from the central population register and consists of people aged 18-59 years per 1st October 1990. People in this panel were interviewed again in 1995, 2000 and 2005 irrespective of participation in previous rounds.

Seven other additional panels are represented in the study. The '1995-age panel', '2000-age panel' and '2005-age panel' were based on random samples drawn in 1995, 2000 and 2005 respectively, consisting of people who were 18-22 years per 1st October in the relevant year. These samples were drawn to adjust for the ageing of the 1990-panel.

The '1995-immigration panel', '2000-immigration panel 'and '2005-immigration panel' were based on samples drawn in 1995, 2000 and 2005, respectively, consisting of people who lived in the country on 1st October in the relevant year, but did not live in Denmark exactly 5 years previously. These samples were drawn to adjust for migration.

People in the age and immigration panels from previous rounds were reinterviewed in later rounds irrespective of participation in the first round. The relative size of each panel reflects the proportion of the relevant groups of the total population - each panel represents around 1/330 of the national population.

In 2005 a new additional base line of adults was drawn in order to increase statistical power in the study.

The 1990 sample consisted of 9,653 people living in Denmark, of which 8,664 participated (90 %). The combined 1995 sample consisted of 10,702 people living in Denmark, of which 8,583 participated (80%). The combined 2000 sample consisted of 11,437 people living in Denmark, of which 8,583 participated (75%).  The combined 2005 sample consists of  19.894 people living in Denmark, participation rate not yet determined.

In each round, people who were employees at the time of interview or had been employees within two months prior to the interview were asked several questions regarding working conditions and occupational exposures. In each round prior to 2005, more than 5,000 were employees.

The variable name can be used to determine what panel the question originates from. The year is stated as the first two numbers after the letters in the variable name as either 90, 95, 00 or 05. If there are more numbers given these state the number of possible answers. Identical variables are given the same name.

The study is completed by The National Research Centre for the Working Environment (NRCWE).
