Abstract Background The use of chemical pesticides without proper health literacy (HL) and necessary pesticide protective behaviors (PPB) can result in adverse effects on human health. Methods This study aims to determine if there is a correlation between HL and PPB among farmers in the Nakhon Ratchasima province, using a random sample of 464 farmers. Structured interviews consisted of three parts: 1. General information, 2. Health literacy (including knowledge, understanding, and other sub-aspects), and 3. Protective behaviors against chemical exposure. Each part of the questionnaire had a reliability index of 0.60 or higher. The reliability of the 2nd and 3rd parts of the questionnaire were as follows: sub-sections of part 2 had a Kuder-Richardson (KR-20) coefficient of 0.79 and Cronbach's alpha (α) coefficient of 0.85–0.86, while part 3 had an α of 0.88. Risk of chemical exposure was assessed using a Cholinesterase Reactive Paper test administered by a finger-prick blood test. Data was analyzed using the Spearman correlation and binary logistic regression. The study was reviewed by the Human Research Ethics Committee with the approval date: August 9, 2021 and expiry date: August 9, 2022. Results Most participants had moderate levels of overall HL (48.8%) and PPB (44.6%). There was a statistically significant positive correlation between HL and PPB (r s (478) = 0.70, p < .005). Logistic regression analysis demonstrated that HL had a statistically significant positive association with PPB (p < .001, OR = 6.57, 95% CI 3.95, 10.94) and was associated with blood cholinesterase levels. Conclusion These findings highlight the need for increased health literacy among farmers in Thailand to ensure correct protective behaviors against chemical exposure and reduce the adverse effects of pesticide exposure on human health.
