3) Job Exposure Matrix Analyses of Psychosocial Factors and Healthy Ageing in Denmark (JEMPAD)
The Job Exposure Matrix Analyses of Psychosocial Factors and Healthy Ageing in Denmark (JEMPAD) is a large-scale, nationwide register-based cohort study examining the relationship between psychosocial working conditions and long-term health outcomes. The study integrates detailed employment data with job exposure matrices (JEMs), health registers, and sociodemographic information to enable longitudinal analyses of work-related risk factors.
Denmark.
Type of Study
A nationwide, register-based cohort study with longitudinal follow-up.
Data Collection
The cohort was established in the year 2000 and linked to annually updated job exposure matrices that assign psychosocial work exposures based on occupational codes. Individual-level data from national registers are linked using unique personal identifiers, allowing continuous follow-up of employment, exposures, and health outcomes over time.
Sample Size
The study includes 1,680,214 individuals.
Sample Size Characteristics
The cohort comprises all employed individuals residing in Denmark in the year 2000 who were aged 30–59 years and had complete data on age, sex, and migration background. The study population is therefore nationally representative of mid-life workers in Denmark at baseline.
Measurement of Mental Health
Mental health outcomes are assessed through linkage to national health registers, including information on in- and outpatient psychiatric hospital contacts recorded in the Danish National Patient Register using ICD-10 diagnostic codes.
In addition, psychosocial risk factors related to mental health—such as emotional demands at work—are measured using job exposure matrices (JEMs), which assign exposure levels based on occupation rather than individual self-report.
