Abstract:
A population-based case-control study of 173 White men with multiple myeloma (MM) and 650 controls was conducted in Iowa (United States), an area with a large farming population, to evaluate the association between MM, agricultural risk factors, and exposure to individual pesticides. A slight nonsignificantly elevated risk for MM was seen among farmers (odds ratio [OR] = 1.2, 95 percent confidence interval [CI] = 0.8-1.7). Although slight excesses were observed, there were no significant associations between MM and handling either classes of pesticides or specific pesticides. Thus, this study found little evidence to suggest an association between risk of MM and farming or pesticides.
Insights
This study found little evidence linking farming or pesticide exposure to multiple myeloma (MM) risk in White men. Further research is needed to explore potential agricultural risk factors for this cancer.
Area of Science:
- Epidemiology
- Occupational Health
Background:
- Multiple myeloma (MM) is a cancer affecting plasma cells.
- Agricultural work and pesticide exposure are potential risk factors for MM.
Purpose of the Study:
- To investigate the association between farming, pesticide exposure, and multiple myeloma (MM) risk.
- To evaluate specific agricultural risk factors and individual pesticide exposures in relation to MM.
Main Methods:
- Population-based case-control study in Iowa, USA.
- Included 173 White men with MM and 650 controls.
- Assessed agricultural activities and pesticide handling.
Main Results:
- A slight, nonsignificant increase in MM risk was observed among farmers (OR = 1.2, 95% CI = 0.8-1.7).
- No significant associations were found between MM and handling pesticide classes or specific pesticides.
Conclusions:
- Limited evidence suggests farming or pesticide exposure is associated with MM risk.
- Further investigation into agricultural risk factors for multiple myeloma is warranted.
