ABSTRACT

Background: Chronic exposure to organophosphate pesticides can increase the risk of neuropsychiatric disorders, including depression and anxiety. Unsafe behavior from farmers will endanger the health of farmers, especially in the form of neuropsychiatric disorders (depression and anxiety). This study aimed to analyze the effects of pesticide exposure and psychosocial determinants on depression and anxiety.

Subjects and Method: A retrospective cohort study was conducted in Sukoharjo, Central Java. The study population was rice farmers. A sample of 200 rice farmers who use organophospate pesticide was selected by fixed exposure sampling. The dependent variable was neuropsychiatry (anxiety and depression). The independent variables were exposure to

organophospate pesticide, had family history of depression, loss and grief, post trauma, work stress, and the use of personal protective equipment (PPE). The data were collected by questionnaire and analyzed by a multiple linear regression.

Results: The risk of depression increased with high exposure to organophospate pesticide (b= 0.15; 95% CI= 0.05 to 0.26; p= 0.005), had family history of depression (b= 5.10; 95% CI= 2.60 to 7.60; p<0.001), loss and grief (b= 2.94; 95% CI= 0.76 to 5.11; p= 0.008), post trauma (b= 2.57; 95% CI= 0.24 to 4.89; p= 0.031), and work stress (b= 0.16; 95% CI= 0.05 to 0.27; p= 0.005). The risk of depression decreased with the use of PPE (b= -0.69; 95% CI= -1.32 to -0.076; p= 0.028). The risk of anxiety increased with high exposure to organophospate pesticide (b= 0.13; 95% CI= 0.02 to 0.24; p= 0.025), post trauma (b= 5.96; 95% CI= 3.48 to 8.44; p<0.001), loss and grief (b= 3.39; 95% CI= 1.07 to 5.71; p<0.001), had family history of depression (b= 2.95; 95% CI= 0.29 to 5.62; p= 0.004), and work stress (b= 0.19; 95% CI= 0.07 to 0.30; p=0.002). The risk of anxiety decreased with the use of PPE (b= -0.09; 95% CI= -1.57 to -0.024; p=0.008).

Conclusion: The risk of depression increases with high exposure to organophospate pesticide, family history of depression, loss and grief, post trauma, and work stress. The risk of depression decreases with the use of PPE. The risk of anxiety increases with high exposure to organophospate pesticide, post trauma, loss and grief, had family history of depression, and work stress. The risk of anxiety decreases with the use of PPE.
