Asthma is a common childhood disease. Its occurrence varies from one place to another, the frequency of which differs between age group. These maps show the spatial variation of severe asthma cases projected from a series of studies conducted on kindergarten children (age 4-6) and adolescents (age 13-15). Apparently severe asthma is common in younger children. Data in the maps were obtained from a study in Hong Kong (Professor Gary Wong, The Chinese University of Hong Kong.) under the auspices of the International Study of Asthma and Allergies in Childhood (ISAAC) in 2002/ 2003.

Top map shows the incidence in percentage of severe asthma of children at age 4-6 while the bottom map age 13-15 illustrated by districts in Hong Kong. The smaller maps indicate the proportional distribution of study cases by districts. The darker colour means a higher incidence. In addition, the North district gave the highest incidence of severe asthma in children at age 4-6 compared to other districts.

哮喘是兒童常見的疾病。不同的地方及不同年齡組別均有不同的發病率。這些地圖是一系列研究調查中幼稚園組(四至六歲)及青少年組(十三至十五歲)嚴重哮喘病例於中空間分佈的差異。嚴重哮喘在年紀小的兒童中較為常見。地圖數據源於香港一項研究(黃永堅教授,香港中文大學),是『國際兒童時期哮喘及過敏症研究調查』(ISAAC)二零零二/二零零三的一部份。

上圖顯示香港十八區患有嚴重哮喘的四至六歲兒童發生率百份比,而下圖是十三至十五歲。小圖示是患有嚴重哮喘的研究參加者比率,越深色表示發生率越高。此外,比較其他分區北區擁有最多四至六歲兒童的嚴重哮喘發生率。
