ABSTRACT. This study aimed to identify factors influencing poisoning symptoms among 153 mixed
insecticide–exposed vegetable farmers in one Cambodian village, where 153 factory workers were
selected as a comparative nonexposed group. The research instruments were questionnaires and reactive-
paper test kits. The majority of vegetable farmers were male, with approximately 87% of the total
participants with an average age of 34 years. The personal hygiene scores of most vegetable farmers
(108; 70.8%) were moderate, and knowledge scores were at poor level (131; 85.6%). Abnormally low
cholinesterase (ChE) levels were detected among 119 (77.8%) farmers. Multiple logistic regression
analysis was used to identify factors associated with possible poisoning symptoms. This study found
that mixing an average of four to six types of insecticides (odds ratio [OR] = 4.6; P = .03) and abnormal
ChE level (OR = 4.09; P = .004) was associated with central nervous system (CNS) symptoms. Age
group >45 years (OR = 2.8; P = .04) and type of vegetable “other” (OR = 2.73; P = .02) were associated
with gastrointestinal symptoms. Type of insecticide, organophosphates (OPs) and carbamates
(CMs) (OR = 3.2; P = .04), was associated with respiratory symptoms. It is recommended that farmers
