To explore the characteristics of spatial-temporal prevalence and public attention of dry eye diseases (DED) through Baidu Index (BI) based on infodemiology method.
The data about BI of DED were collected from Baidu search engine using "Dry eye diseases" as keyword. The spatial and temporal distribution of DED were analyzed through timeseries data decomposition as well as spatial autocorrelation and hotspot detection of BI about DED. The most popular related words and demographic characteristics were recorded to determine the public attention of DED.
The trends of BI about DED in Chinese mainland had gradually increased over time with a rapid increase from 2012 to 2014 and in 2018. The results of timeseries decomposition indicated that there was seasonality in the distribution of BI about DED with the peak in winter, especially in northern regions. The geographic distribution demonstrated the search activities of DED was highest in the east of Chinese mainland while lowest in the west. The vast majority of people searching for DED were teenagers (20-29 years), with a predominance of females. Glaucoma, keratitis and conjunctivitis were the diseases most often confused with DED, and the artificial tears were the most common treatment for DED in Chinese mainland according to the BI about DED.
The analysis revealed the seasonality, geographic hotspots and public concern of DED through BI in Chinese mainland, which provided new insights into the epidemiology of DED.
运用基于信息流行病学的百度指数（BI）探索干眼病（DED）时空流行和公众关注度的特征。
使用“干眼病”作为关键词，从百度搜索引擎中收集关于 DED 的 BI 数据。通过时间序列数据分解，以及 DED 的 BI 的空间自相关和热点检测，分析 DED 的时空分布。记录最受欢迎的相关词汇和人口统计学特征，以确定 DED 的公众关注度。
中国大陆 DED 的 BI 趋势随时间逐渐增加，2012 年至 2014 年和 2018 年呈快速增长。时间序列分解的结果表明，DED 的 BI 分布具有季节性，冬季高峰明显，尤其是在北方地区。地理分布显示，DED 的搜索活动以中国大陆东部最高，西部最低。搜索 DED 的绝大多数人是青少年（20-29 岁），女性居多。根据 DED 的 BI，青光眼、角膜炎和结膜炎是最常与 DED 混淆的疾病，人工泪液是中国大陆治疗 DED 的最常见方法。
本研究通过中国大陆的 BI 分析揭示了 DED 的季节性、地理热点和公众关注度，为 DED 的流行病学提供了新的见解。
