Assessment of relationship between farmer's syndrome and neurotoxic symptoms in farming couples.

The purpose of this study was to evaluate the relationship between farmer's syndrome and neurotoxic symptoms in farming couples. The study was conducted on 348 farmers (174 couples) in Chungnam Province of South Korea. We obtained information on general and agricultural characteristics, farmer's syndrome, and neurotoxic symptoms through face-to-face surveys from 2014 to 2019. The Korean version of the diagnostic standard scale was used for farmer's syndrome, and the Swedish Q16 questionnaire was used for neurotoxic symptoms. Logistic regression analysis was used to identify neurotoxic symptoms affected by farmer's syndrome. The prevalence of 'positive' neurotoxic symptoms was higher in wives (72.4%) than in husbands (56.9%). Compared with husbands with 'negative and probable' farmer's syndrome (reference), husbands with 'positive' farmer's syndrome were more likely to have 'positive' neurotoxic symptoms (odds ratio [OR] = 5.37, 95% confidence interval [CI] = 2.01-14.30). Compared with wives with 'negative and probable' farmer's syndrome (reference), wives with 'positive' farmer's syndrome were more likely to have 'positive' neurotoxic symptoms (OR = 7.07, 95% CI = 2.58-19.38). Therefore, neurotoxic symptoms in both husbands and wives were significantly associated with farmer's syndrome. However, wives had a higher risk of neurotoxic symptoms than husbands. The findings of this study might be useful as important data for establishing and training agricultural safety and health policy.
