Study Findings

AHS research has led to more than more than 200 papers in the peer reviewed scientific literature. Findings are shared with participants and agricultural organizations through Newsletters and Study Updates. Research has focused on cancer in applicators, spouses, and children; reproductive health; respiratory health; neurological symptoms and disease; diabetes; thyroid disease; rheumatoid arthritis and other autoimmune diseases; injury; and mortality among other topics. Increasingly research in the cohort has included incorporation of biomarkers of exposure or effect and includes studies of gene-pesticide interactions in relation to disease risk.


Since the study began in 1993, the data contributed by study participants has led to scientific papers on a wide range of topics related to the health of farm families and others working in agriculture
