The Effects of Household air Pollution Due to Burning of Mosquito Coils on Respiratory Problems in Myanmar Migrants in Mae Sot District, Tak Province, Thailand

Abstract

The objective of this cross-sectional study was to invite whether household burning of mosquito coils is associated with increased risk of respiratory problems among Myanmar migrant workers in Mae Ku village, Mae Sot district, Tak Province, in Thailand. 412 adult female respondents and 153 children (under 7 years old) were included in the study. The data were collected using a standardized, pretested interviews-administered questionnaire in March 2010. Prevalences of respiratory symptoms such as cough with or without colds, phlegm with or without colds, phlegm with or without colds, shortness of breath, sore throat without cold, rhinitis and eye irritation at home were assessed in relation to mosquito coil use and other independent variables that could also be associated with respiratory symptoms. In respondents, mosquito coil use was significantly associated with cough with or without colds (p<0.001) and phlegm with or without colds (p=0.011). Wheeze with or without colds (p=0.091) was marginally significantly d t e d with mosquito coil use. In children, mosquito coil use was significantly associated with cough with or without colds (p=0.007) and rhinitis (p=0.042). These results suggest that mosquito coil burning is a respiratory risk factor in the study population, although confounding with other factors cannot be ruled out. If these associated are confirmed in W e r research, other methods of controlling exposure to mosquitoes should be sought for preventing diseases such as malaria and dengue fever. Risks and benefits of mosquito coil burning should be characterized.
