Prevalence of abnormal ChE levels both AChE and PChE
In farmer group, the prevalence of abnormal AChE levels was 31.4%. In non-farmer group, the prevalence of abnormal AChE levels was 14.3%. The results showed that the prevalence of abnormal AChE levels in the farmer group was likely more than in the non-farmer group.
According to PChE levels, 25.7 % of the farmers had normal PChE levels and 74.3% of them had abnormal PChE levels, while all of the non-farmers had normal PChE levels. The prevalence of normal PChE levels in the non-farmer group was higher than in the farmer group (t-test, p=0.000). The results showed the farmers may be getting more risk than the non-farmers.
