A total of 588 workers were assessed during the study; 300 in 2014 and 288 in 2015. Our objective was to try to recruit a representative sample of Latino farmworkers: both male and female, direct and contractor hired. 93.6% identified Mexico as their country of origin. More than two-thirds (69.3%) of these Mexican immigrants reported having a 6th grade education level or less. The average age of the participant was 38 years and many of them have worked over a decade in agricultural labor.
The Core body temperature was monitored over the whole work shift. Weight and blood concentration (indicators of hydration status) were monitored both during pre and post-shift. Liquid consumption was reported by the worker at the end of the work shift.
Although the majority of participants reported having access to water and drinking at least 3-4 times per hour during their work shift, 208 workers still showed weight loss and the end of their work day. 26 workers lost more than 1.5% of body weight, indicating a measure of heat strain and dehydration stated by the Centers for Disease and Control and Prevention (CDC).
Further analysis is continuing and website will be updated with more insight addressing each of the dimensions surrounding HRI in farm workers.
