Investigation of indoor molds and allergic diseases in public primary schools in Edirne city of Turkey.

ABSTRACT

Background:Studies evaluating the role of indoor molds in the development of allergic or respiratory symptoms in schools are few in childhood. Methods:Ten public primary schools were included into the study. A thorough assessment, using a questionnaire and inspection surveys was carried out. The concentration of culturable mold was assessed in the dust samples in the schools. Indoor temperature and humidity were measured. A total of 1374 students who completed valid questionnaires were included in the study, and dust-samples were collected from the schools. Results: Cumulative and current prevalence rates of wheezing, asthma, allergic rhinitis, and atopic dermatitis were found as 31.4%, 9.3%, 16.2%, 6.0% and 13.4%, 11.9%, 15.1%, 2.1%, respectively. The most frequent mold-species detected in indoor dusts were Cladosporium, Penicillium, Alternaria and Aspergillus. Although the prevalence rates of allergic diseases and respiratory symptoms were high, indoor mold amounts were low in the schools in our region and no significant correlation was determined between indoor mold amount and the prevalence of these diseases in schools or classrooms. Conclusion: Even though allergic molds are present in schools, the mold-exposure may not be an important predisposing factor for development of allergic and respiratory diseases the schools in our region. Objective: This study aimed to investigate relation between indoor molds and allergic diseases or respiratory symptoms in primary school’s children in Edirne, Turkey.
