In the past, medical literature reflected that diet was not a proven cause of acne. However, studies in recent years have substantiated a link between certain dietary factors and acne. It is unclear whether patients are aware of recent research findings.
Acne patients were surveyed to explore beliefs regarding the link between diet and acne, to determine whether these beliefs translated into behavior change and to identify health information sources.
PATIENTS/METHODS: Upon Institutional Review Board (IRB) approval, surveys were administered to 50 acne patients at an academic dermatology clinic in 2014, with 49 completed in full and included in this analysis.
Ninety-two percent of respondents believed that diet could affect acne. Seventy-one percent attempted to change their diet to improve acne. Seventy-one percent believed acne to be caused by fried or greasy foods, although chocolate (53%), dairy (47%), and soda drinks (35%) were highly implicated. Patients obtained information from Google searches (49%), dermatologists (43%), family members and TV (41% each), and medical websites (31%).
In this exploratory study, patients reported utilizing a diversity of information sources, a majority from the Internet. In those surveyed, there was a persistence of long-held belief that fried/greasy foods and chocolate may serve as acne triggers, and less belief in trigger foods supported by recent research, including refined carbohydrates and sugar. Given the multiplicity of beliefs and utilized sources among acne patients in our survey, there is a need to establish up-to-date and reliable methods to educate patients on diet and acne.
过去，医学文献表明饮食并非已证实的痤疮病因。然而，近年来的研究证实了某些饮食因素与痤疮之间的联系。目前尚不清楚患者是否知晓这些最新研究结果。
对痤疮患者进行调查，以探究他们对饮食与痤疮之间联系的看法，确定这些看法是否转化为行为改变，并识别健康信息来源。
患者/方法：在获得机构审查委员会（IRB）批准后，2014年对一家学术皮肤科诊所的50名痤疮患者进行了调查，其中49份问卷全部完成并纳入本分析。
92%的受访者认为饮食会影响痤疮。71%的人试图改变饮食以改善痤疮。71%的人认为痤疮是由油炸或油腻食物引起的，尽管巧克力（53%）、乳制品（47%）和苏打饮料（35%）也被高度认为有关。患者通过谷歌搜索获取信息（49%），皮肤科医生（43%），家庭成员和电视（各41%），以及医学网站（31%）。
在这项探索性研究中，患者报告使用了多种信息来源，其中大部分来自互联网。在接受调查的人群中，长期以来一直认为油炸/油腻食物和巧克力可能是痤疮的诱发因素，而对于近期研究支持的诱发食物，包括精制碳水化合物和糖，认可度较低。鉴于我们调查中痤疮患者的看法和使用的信息来源多种多样，有必要建立最新且可靠的方法来对患者进行饮食与痤疮方面的教育。
