Determination and assessment of impact of environmental triggers/ allergens and asthma severity in children in a tertiary care teaching hospital

The present study is to assess the association between environmental triggers and asthma severity in children. The parental questionnaire was obtained from 500 respondents (202 non asthmatic & 298 asthmatic) between the age of 2-15. The questionnaire consists of patient demographic details, socio economic status, family history of asthma/atopy and environmental risk factors which leads to asthma exacerbation. Most of the patients were diagnosed with controlled (45%) or uncontrolled (15%) asthma. In controlled asthmatic, about 40.99% of the patients were within the age between 2-5 where as in uncontrolled asthmatic 36.88% belongs to the age between 6-10.The family history of asthma were significant among 27.5%. Boys have more predominance of asthma incidence than girls. Majority of the asthmatic patient were reported with lower socio economic status. There was no significant association between domestic animals, rat/mice, cockroach allergy, mould /dampness, exposure to parental smoking, vegetation and development of asthma in paediatrics. The study suggests that there is a positive relationship between seasonal exacerbation, dust allergy and outdoor pollutants with the asthma severity in children.
