In Thailand, the surveys of allergic rhinitis on children were found about 13-44% while the prevalence of allergic rhinitis in Thai adults was as high as 20%. The information of the prevalence of allergic rhinitis in the suburban area has not been continuously done especially in the adult population.

OBJECTIVE:

To present study the prevalence of allergic rhinitis and other atopic diseases and to determine the aeroallergen sensitivity of allergic patients in suburban area.

MATERIAL AND METHOD:

Observational descriptive cross-sectional study as one-stage cluster sampling, Using ISAAC questionnaires interviewed adults at War Intaram community, Hua Raeu, Phra Nakhon Si Ayutthaya District, Phra Nakhon Si Ayutthaya Province, Thailand during September-October 2008. Participants who had allergic rhinitis symptoms described in the questionnaires were enrolled to perform the skin prick test voluntary to determine the aeroallergen sensitivity.

RESULTS:

There were 324 subjects, female 64.8% and male 35.2%. Age ranges between 20-66 years old (mean 42.2). The prevalence of allergic rhinitis, asthma and chronic pruritic rash were 37.7%, 16%, 21.3% and history of allergic rhinitis, asthma and chronic pruritic rash within 12 months were 32.1%, 10.5%, 17.3%.
