Comparative Analysis of the Prevalence of Atopic Dermatitis in Elementary Schoolchildren in Kaohsiung and Penghu County

摘要


In Taiwan, local data about the atopic dermatitis (AD) prevalence have been insufficient. We survey the AD prevalence in schoolchildren and compare its difference between Kaohsiung and Penghu county in a cross-sectional point-prevalence study. Seven elementary schools in Kaohsiung county and four in Penghu county were selected and schoolchildren were examined by dermatologists in June 2004 and 2005, respectively. Totally 4,267 schoolchildren (2296 boys, 1971 girls) in Kaohsiung county were investigated, in which 69 were diagnosed as AD, with more boys affected than girls (1.46:1). In Penghu county, 142 AD cases were identified among 3,289 schoolchildren (1693 boys, 1596 girls), with also more boys affected than girls (1.49:1). Prevalence in high-grade students was lower than those in mid- and low-grade students (1.80%vs. 3.42%, p<0.01). The point-prevalence of AD was significantly higher in Penghu than in Kaohsiung county (4.32%vs. 1.62%, p<0.01). Higher humidity may partially explain the higher AD prevalence in Penghu than in Kaohsiung county. Further extensive study is necessary to explain the difference of AD prevalence in different regions of Taiwan.
