Main aim of cohort, please briefly describe the main objectives of the cohort
  To determine the rates of mortality and of cancer incidence in a cohort of pesticide-exposed Australian workers.
Study design (please select as many as appropriate)
 

  • Retrospective cohort

Source population (please select as many as appropriate)
 

  • Industry / occupation-based

Comparators (please select as many as appropriate)
 

  • Internal study population

Inclusion criteria
  This explores a large cohort of some 13,000 workers who were end-users of pesticides and participated in pesticide biomonitoring programs from the 1960s to the 1990s. Predominantly agricultural workers, this cohort also includes smaller groups of municipal and public utilities workers, and dedicated pest controllers. Linkage to the national cancer and death registries is used in this project to estimate rates of cancers and causes of death in the cohort compared with that of the general population, identifying trends associated with exposure. The cohort will be re-linked to the registries at periodic intervals (eg. five to ten years).
