Effect of Insecticides (Pyrethroids) on Eosinophil Count in School Children

Abstract

Background: Study was conducted in school children to reveal the toxic effects of pyrethroids which causes allergic reactions with in the body especially altered lung function tests and eosinophil count. 
Objective: In the present study, the effects of pyrethroids on eosinophil count of school children were analyzed.
Methodology: The present study is a cross-sectional analytical study. The study was conducted at Government Girls Primary School, Sita Nagar, Karachi including 50 children with ages between 6 – 10 years. They were divided equally into two groups: group A (exposed to insecticidal spray) and group B (exposed to mosquito coil). The correlations between the insecticides (Pyrethroids), and eosinophil by linear regression analysis confirmed that insecticides (Pyrethroids) had a strong correlation with the eosinophil count under study exemplified by the significant increase in Eosinophil count was observed after exposure to mosquito coil whereas there was no association between insecticidal spray and Eosinophil count. Results: There was significant increase in Eosinophil count after exposure to mosquito coil whereas no association was observed between insecticidal spray and Eosinophil count.
Conclusions: The use of spray over the coil is less hazardous to the health.
