Acne vulgaris is a common skin condition in adolescents. The prevalence of acne is thought to vary between ethnic groups and countries. A large-scale community-based study was performed in six cities in China to determine the prevalence and possible risk factors for acne in the Chinese population. A total of 17,345 inhabitants were included in this study. Of these, 1,399 were found to have acne. No acne was found in subjects under 10 years of age, and only 1.6% in the 10-year-old group had acne. Prevalence then increased rapidly with age, up to 46.8% in the 19-year-old group. After that, it declined gradually with age. Acne was rare in people over 50 years of age. In subjects in their late teens and 20s, acne was more prevalent in males, while in those over 30 years of age it was more prevalent in females. In subjects with acne, 68.4% had mild; 26.0% had moderate and 5.6% had severe acne. In adult acne, persistent acne was much more common (83.3%) than late-onset acne (16.7%). Smoking and drinking were found to be associated with adolescent acne, while no association was found between diet and acne. These results suggest that the prevalence of acne in the Chinese population is lower than that in Caucasian populations, and that adult acne is not uncommon in Chinese subjects.
寻常痤疮是一种常见的青少年皮肤疾病。痤疮的患病率被认为在不同种族和国家之间存在差异。在中国六个城市进行了一项大规模的基于社区的研究，以确定中国人群中痤疮的患病率和可能的危险因素。这项研究共纳入了 17345 名居民。其中，有 1399 人患有痤疮。在 10 岁以下的人群中没有发现痤疮，而在 10 岁组中只有 1.6%的人患有痤疮。患病率随后随年龄迅速增加，在 19 岁组中达到 46.8%。之后，随着年龄的增长，患病率逐渐下降。50 岁以上的人很少患有痤疮。在青少年和 20 多岁的人群中，痤疮在男性中更为常见，而在 30 岁以上的人群中，痤疮在女性中更为常见。在患有痤疮的人群中，68.4%为轻度；26.0%为中度，5.6%为重度。在成人痤疮中，持续性痤疮更为常见（83.3%），而迟发性痤疮更为罕见（16.7%）。吸烟和饮酒被发现与青少年痤疮有关，而饮食与痤疮之间没有关联。这些结果表明，中国人群中痤疮的患病率低于白种人群，并且中国人群中并不罕见成人痤疮。
