Recent observational and experimental evidence suggests that diet may contribute to acne prevalence.
To examine the differences in select dietary factors (glycemic index [GI], total sugar, added sugar, fruit/fruit juice, fruit/vegetables, vegetables, saturated fat, trans fat, and number of milk and fish servings per day) between groups of self-reported acne severity. Secondary objectives were to investigate the differences in food-aggravated acne beliefs and acne-specific quality-of-life between groups of self-reported acne severity.
This study utilized a cross-sectional design.
PARTICIPANTS/SETTING: A total of 248 (115 male, 133 female) participants, age 18 to 25 years, completed questionnaires designed to measure self-reported acne severity, select dietary factors, food-aggravated acne beliefs, acne-specific quality-of-life, and anthropometric and demographic characteristics. The Block fat/sugar/fruit/vegetable food frequency questionnaire assessed usual dietary intake. Data were collected in New York City between January and May 2012.
One-way between groups analysis of variance examined differences in dietary factors, anthropometric characteristics, and acne-specific quality-of-life between groups of self-reported acne. χ² tests compared food-aggravated acne beliefs and demographic characteristics between groups of self-reported acne.
Compared with participants with no or mild acne, participants with moderate to severe acne reported greater dietary GI (P<0.001), added sugar (P<0.001), total sugar (P<0.001), number of milk servings per day (P<0.001), saturated fat (P<0.001), and trans-fatty acids (P<0.001), and fewer servings of fish per day (P=0.002). Among all participants, 58.1% perceived diet to aggravate or influence acne.
This study suggests that diet, particularly dietary GI, saturated fat, trans fat, milk, and fish may influence or aggravate acne development. Future research is necessary to elucidate the proposed mechanisms linking diet and acne and determine the impact of medical nutrition therapy on acne development.
最近的观察性和实验证据表明，饮食可能会导致痤疮的发病率上升。
研究自报痤疮严重程度不同组之间选择的饮食因素（血糖指数[GI]、总糖、添加糖、水果/果汁、水果/蔬菜、蔬菜、饱和脂肪、反式脂肪和每天牛奶和鱼类的摄入量）的差异。次要目的是研究自报痤疮严重程度不同组之间食物加重痤疮的信念和痤疮特定生活质量的差异。
本研究采用横断面设计。
参与者/设置：共 248 名（115 名男性，133 名女性）年龄在 18 至 25 岁之间的参与者完成了问卷，旨在测量自报痤疮严重程度、选择饮食因素、食物加重痤疮的信念、痤疮特定生活质量以及人体测量和人口统计学特征。Block 脂肪/糖/水果/蔬菜食物频率问卷评估了习惯性饮食摄入。数据于 2012 年 1 月至 5 月在纽约市收集。
单向组间方差分析比较了自报痤疮严重程度不同组之间的饮食因素、人体测量特征和痤疮特定生活质量的差异。χ²检验比较了自报痤疮严重程度不同组之间食物加重痤疮的信念和人口统计学特征的差异。
与无或轻度痤疮的参与者相比，中重度痤疮的参与者报告了更高的饮食 GI（P<0.001）、添加糖（P<0.001）、总糖（P<0.001）、每天牛奶摄入量（P<0.001）、饱和脂肪（P<0.001）和反式脂肪酸（P<0.001），以及每天鱼类摄入量较少（P=0.002）。在所有参与者中，58.1%的人认为饮食会加重或影响痤疮。
本研究表明，饮食，特别是饮食 GI、饱和脂肪、反式脂肪、牛奶和鱼类，可能会影响或加重痤疮的发展。未来的研究需要阐明饮食与痤疮之间的潜在机制，并确定医学营养疗法对痤疮发展的影响。
