||Objective: Assessing the level of poisoning with the
AChE test due to cotton producer’s pesticide exposure in
the biggest cotton production parts of northern Benin,
and to identifying the risk factors.
Method: By a cross sectional study, we recruited in
two cotton production townships,190 pesticides sprayers
for at least 5 years. They were submitted to a questionnaire
and to acetylcholinesterase (AChE) test using the
Test Mate® model 400 devices (EQM Research Inc) with
main component of the device: photometric sensor and
principle based on the works by Ellman. By a non-probabilistic
sampling, we recruited 190 farmers from the two
townships fulfilling all the inclusion criteria and available
to participate to all stages of the study.
Results: The studied population is essentially young:
83.16% were under 45 years old, with 75% illiterates.
70.3% of the farmers have more than 10 years of spraying
experience. We noted that 2.06 % of the farmers still
used domestic containers to prepare the pesticides. As
precautions to prevent poisoning after spraying, 10.31%
of the surveyed farmers drink milk. There was a significant
AChE decrease between pre-exposure (AChE 3.08 ±
2.3UI / ml) and post-exposure (AChE 2.65 ± 0.52 IU /
ml); p = 0.009. 73.1% of the famers were concerned by that
inhibition. Those who could read the pictograms faced
less inhibition of AChE (p <0.05). The age variables, level of education and experience of pulverization do not have
any influence on AChE inhibition.
Conclusion: AChE monitoring is needed for the surveillance
