Description:Objective
The California Heat Illness Prevention Study devised methodology and collected physiological data to assess Heat Related Illness (HRI) risk in Latino farmworkers.
Methods
Bilingual researchers monitored HRI across a work shift, recording core temperature, work rate (METs) and heart rate at minute intervals. Hydration status was assessed by changes in weight and blood osmolality. Personal data loggers and a weather station measured exposure to heat. Interviewer administered questionnaires were used to collect demographic and occupational information.
Results
California farmworkers (n=588) were assessed. Acceptable quality data were obtained from 80% of participants (core temperature) to 100% of participants (weight change). Workers (8.3%) experienced a core body temperature ≥ 38.5°C and 10.8% experienced dehydration (lost more than 1.5% of body weight).
Conclusions
Methodology is presented for the first comprehensive physiological assessment of HRI risk in California farmworkers.
