Participation in pooled analyses
 

  • The cohort is potentially interested in participating in pooled analyses of (European) occupational cohort studies (note pooled analyses also includes remote decentralized analyses that would not require any transfer of primary data as well as meta-analyses).

Main aim of cohort, please briefly describe the main objectives of the cohort
  We set up the population-based Occupational and Environmental Health Cohort Study (AMIGO) to longitudinally study occupational and environmental determinants of diseases and wellbeing from a multidisciplinary and lifetime point of view. Determinants include chemical, biological, physical (e.g. electromagnetic fields), and psychosocial factors. Priority health outcomes include cancer, neurological, cardiovascular and respiratory diseases and non-specific symptoms. Owing to the recruitment strategy via general practitioners of an established network, we also collect longitudinal data on health outcomes registered in their electronic medical records including symptoms, diagnosis, and treatments. This created the unique opportunity to assess potential health-related participation bias by comparing general practitioner-registered prevalence rates in the cohort and the source population.
Study design (please select as many as appropriate)
 

  • Prospective cohort

Source population (please select as many as appropriate)
 

  • General population: National

Comparators (please select as many as appropriate)
 

  • Internal study population

Inclusion criteria
  We aimed to sample the general adult population of the Netherlands and decided to select 31-65 years olds for various reasons, e.g. working age as occupational exposure is a main determinant, and the age of onset of our main health outpoints. Our recruitment strategy was to invite subjects through 99 general practices that are part of a nation-wide information and surveillance network for primary health care established at NIVEL, i.e. the NIVEL Primary Care Database
