Returning Genetic Results on Arsenic Susceptibility

The intervention groups will receive information regarding their genetic results that informs them of their arsenic metabolism efficiency. They will receive this information through a factsheet appropriate for a lay audience. The factsheet will contain information regarding arsenic metabolism and its role in removing arsenic from the body. The factsheet will describe how there is variability among individuals with respect to the efficiency with which arsenic is removed from the body, due to inherited differences in genes that affect arsenic metabolism. The factsheet describe how slower metabolizers remove arsenic slower from the body, which leads to increased in toxicity risk. The factsheet will inform participants in the intervention groups that they have been identified as a slow/fast metabolizer of arsenic based on their genes. This information will be given to participants by the URB staff, with a study physician available to address questions and concerns from the participant.

In this study, intervention and control groups will receive a standard informational intervention which will remind them of the effects of arsenic exposure and potential strategies that can be implemented to reduce their exposure.
