Interpret level of cholinesterase: if it values less than or equal 50% from normal it indicates possible pesticide poisoning and should be removed from the exposure and/or treated with anticholinergics [12]. A cholinesterase level of more than 50% from the normal value is considered normal. Using the licensed SPSS version 17 for windows, general characteristics and socio-demographic were described by frequency, percentage, and mean. Independent T-Test was used to determine the difference between blood cholinesterase levels of farmer group and non-farmer group. Chi-square was used to find relation between pesticides use and blood cholinesterase level and a relationship between health effects and level of blood cholinesterase. An odds ratio (OR) is a measure of association between an exposure and an outcome. The OR represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure. OR equal 1 indicated that exposure does not affect odds of outcome. OR more than 1 that means exposure associated with higher odds of outcome. OR less than 1 indicated that exposure associated with lower odds of outcome. The OR was used to explain a relationship between health effect and pesticide exposure.
