Table 2 Variable description and factors utilized to build indicators measuring exposure

From: Assessing biomarkers and neuropsychological outcomes in rural populations exposed to organophosphate pesticides in Chile – study design and protocol

Exposure

Variable description

Variable construction

Environmental

Number of days living in farming area

Number of years living in farming area times 365 (days per year)

Occupational

Life-long occupational exposure (days)

Number of years living in farming area times 365 (days per year) + (number of years working in contact with pesticides times number of days working per year*)

 

“Adjusted Life-long Exposure to Pesticides” - ALLOEP score

The result from the upper row amplified by 3-fold increase of exposure

  1. (*) Number of months per year working in contact with pesticides, according to information declared in the questionnaire for seasonal workers.
