The effects of particulate matter on atopic dermatitis symptoms are influenced by weather type: Application of spatial synoptic classification (SSC)

This data set is built to investigate how the effects of particulate matter (PM) on atopic dermatitis (AD) symptoms are influenced by weather type. A total of 125 young children (76 boys and 49 girls) under six years of age with AD living in Seoul, Korea, were enrolled as a panel and followed for 17 months between August 2013 and December 2014. Data include symptom presence, PM2.5, PM10, temperature, relative humidity, and weather type which includes dry moderate (DM), dry polar (DP), dry tropical (DT), moist moderate (MM), moist polar (MP), and moist tropical (MT), plus a transitional (TR) category, on a daily basis. Age, sex, SCORAD at enrollment, presence of fever as a proxy for infection, use of topical corticosteroids (TCS), and day of week (DOW) are also included as confounding factors. Exposure to PM2.5 and PM10 by each individual was estimated with time-weighted average concentrations, considering outdoor and indoor levels of PMs and time-activity of each individual.

本数据集旨在探究大气颗粒物（particulate matter, PM）对特应性皮炎（atopic dermatitis, AD）症状的影响如何受天气类型调控。本研究共招募125名居住于韩国首尔的6岁以下特应性皮炎患儿作为研究队列，其中男童76名、女童49名，于2013年8月至2014年12月期间开展为期17个月的随访。数据集每日维度的记录内容包括：症状发生情况、PM2.5浓度、PM10浓度、气温、相对湿度，以及天气类型（含干燥温和型(DM)、干燥极地型(DP)、干燥热带型(DT)、湿润温和型(MM)、湿润极地型(MP)、湿润热带型(MT)，外加过渡型(TR)类别）。此外，本数据集还纳入年龄、性别、入组时SCORAD评分、以发热作为感染的替代指标、局部糖皮质激素（topical corticosteroids, TCS）使用情况、星期几（DOW）作为混杂因素。个体暴露于PM2.5与PM10的水平通过时间加权平均浓度估算，该估算综合考虑了颗粒物的室外与室内浓度水平以及每名研究对象的时间活动模式。
