In this study, we investigated the status of researching drug information online, and the type of Internet user who uses anonymous Web communities and websites. A Web-based cross-sectional survey of 10875 male and female Internet users aged 16 and over was conducted in March 2010. Of 10282 analyzed respondents, excluding medical professionals, about 47% reported that they had previously searched the Internet for drug information and had used online resources ranging from drug information search engines and pharmaceutical industry websites to social networking sites and Twitter. Respondents who had researched drug information online (n=4861) were analyzed by two multivariable logistic regressions. In Model 1, the use of anonymous websites associated with age (OR, 0.778; 95% CI, 0.742-0.816), referring to the reputation and the narrative of other Internet users on shopping (OR, 1.640; 95% CI, 1.450-1.855), taking a prescription drug (OR, 0.806; 95% CI, 0.705-0.922), and frequent consulting with non-professionals about medical care and health (OR, 1.613; 95% CI, 1.396-1.865). In Model 2, use of only anonymous websites was associated with age (OR, 0.753; 95% CI, 0.705-0.805), using the Internet daily (OR, 0.611; 95% CI, 0.462-0.808), taking a prescription drug (OR, 0.614; 95% CI, 0.505-0.747), and experience a side effect (OR, 0.526; 95% CI, 0.421-0.658). The analysis revealed the profiles of Internet users who researched drug information on social media sites where the information providers are anonymous and do not necessarily have adequate knowledge of medicine and online information literacy.
在本研究中，我们调查了在线搜索药物信息的状况，以及使用匿名网络社区和网站的互联网用户类型。2010年3月，我们对10875名年龄在16岁及以上的男性和女性互联网用户进行了一项基于网络的横断面调查。在10282名被分析的受访者中，排除医学专业人员后，约47%的人报告称他们此前曾在互联网上搜索过药物信息，并使用过从药物信息搜索引擎、制药行业网站到社交网站和推特等在线资源。对曾在网上搜索过药物信息的受访者（n = 4861）进行了两项多变量逻辑回归分析。在模型1中，使用匿名网站与年龄相关（比值比[OR]，0.778；95%置信区间[CI]，0.742 - 0.816），参考其他互联网用户在购物方面的声誉和评价（OR，1.640；95% CI，1.450 - 1.855），服用处方药（OR，0.806；95% CI，0.705 - 0.922），以及经常与非专业人员咨询医疗保健和健康问题（OR，1.613；95% CI，1.396 - 1.865）。在模型2中，仅使用匿名网站与年龄相关（OR，0.753；95% CI，0.705 - 0.805），每天使用互联网（OR，0.611；95% CI，0.462 - 0.808），服用处方药（OR，0.614；95% CI，0.505 - 0.747），以及经历过副作用（OR，0.526；95% CI，0.421 - 0.658）。分析揭示了在社交媒体网站上搜索药物信息的互联网用户的特征，这些网站上的信息提供者是匿名的，且不一定具备足够的医学知识和在线信息素养。
