^bTime that participants are exposed to farm work and farm worksites are the individual farm exposures under study. Farm injuries are the primary outcomes. Characteristics of the settings (context) in which farm people work and/or live may have a moderating influence on exposure-outcome relationships. In the SFIC, we hypothesize that when farm people are in positive contextual settings, associations between exposures and injury will be attenuated, after controlling for key confounders.
