Cancer mortality risks for Wisconsin white male farmers were examined during the years 1981 to 1990. Four malignancies were studied: Non-Hodgkin's lymphoma, melanoma, colon cancer, and rectal cancer. Occupation coded deaths were segmented into farmer and nonfarmer groups and population counts for the groups were estimated from 1980 and 1990 Bureau of the Census data. Standardized mortality ratios (SMRs) were constructed from the ratio of observed farmer deaths and the expected number of farmer deaths. Expected deaths were generated from the underlying statewide nonfarmer rate for the malignancy multiplied into the farmer population at risk. Farmers had significantly lower mortality risks for melanoma (SMR: 0.659; 95% CI: 0.993-0.326) and colon cancer (SMR: 0.763; 95% CI: 0.928-0.599). Farmers also exhibited a nonsignificant decrement for non-Hodgkin's lymphoma (SMR: 0.930; 95% CI: 1.214-0.645). For rectal cancer, farmers experienced a slightly higher but essentially the same risk as nonfarmers (SMR: 1.013; 95% CI: 1.418-0.608)--the SMR was not significant. This study corroborates a number of cancer incidence and mortality investigations demonstrating that farmers generally experience the same or lower mortality risks for these malignancies.

Cumulative sun exposure has been linked to about 95 percent of all skin cancers. Farmers and their families, by nature of their occupations, are exposed to an abundance of sun over a long period of time and, therefore, are at an increased risk for skin cancer. Because education is known to be a primary means of health, Future Farmers of America (FFA) peer facilitators (teen educators) provided third graders in rural communities sun protection education with the hope that the message would reach the entire family. The FFA facilitators (n = 217) from 39 FFA organizations throughout Wisconsin were trained with skin cancer and sun protection information. The FFA facilitators then gave presentations on sun protection to third graders (n = 2,007) in their school districts. Control schools included 57 facilitators and 669 third graders. Evaluation involved pre-, post-, and six-month follow-up surveys testing knowledge gained by the third graders. Students who correctly responded to a question on the post-survey after incorrectly answering it on the pre-survey were said to have had a knowledge gain for that question. By using chi-square tests, the intervention group demonstrated a statistically significant (P < 0.001) higher proportion of students experiencing knowledge gain than did the control group from pre- to post-surveys for nine of the 10 questions. Summary statistics were used to describe the study population. In addition to skin cancer knowledge questions, the survey of facilitators included sun protection behavior and attitude questions. This intervention was able to use peer educators as instructors to demonstrate knowledge gain in the youths of the target population. The pilot project materials costs were +0.55 per third grade student and +3.50 per facilitator. Using a school-based organization such as FFA provided a cost-effective means of reaching the rural population. [ABSTRACT FROM AUTHOR]
