Data about the prevalence of rosacea are scarce. The aim of this study was to evaluate the prevalence rate of rosacea according to the American National Rosacea Society Expert Committee (NRSEC) classification. A cross-sectional study of 348 subjects randomly selected from a working population >or= 30 years of age was performed. All subjects completed a questionnaire. Skin status was examined according to NRSEC criteria. Of the 348 subjects, 78 (22%) had one or more primary features of rosacea. The most common features were erythema (21%) and telangiectasia (18%). Of the subjects with rosacea, 78% had erythematotelangiectatic rosacea and 22% had papulopustular rosacea. Fifteen percent of the study subjects had experienced frequent episodes of flushing without permanent features of rosacea. No significant gender-related differences were found between study groups. In conclusion, according to the NRSEC, rosacea is a more common skin condition over the age of 30 years than previously thought.
有关酒渣鼻患病率的数据较为匮乏。本研究旨在评估美国国家酒渣鼻学会专家委员会（NRSEC）分类下酒渣鼻的患病率。对随机选取的、年龄>or=30 岁的工作人群中的 348 名受试者进行横断面研究。所有受试者均完成一份调查问卷。根据 NRSEC 标准检查皮肤状况。在 348 名受试者中，78 名（22%）存在一种或多种酒渣鼻的主要特征。最常见的特征是红斑（21%）和毛细血管扩张（18%）。患有酒渣鼻的受试者中，78%为红斑毛细血管扩张型，22%为丘疹脓疱型。15%的研究对象曾频繁出现潮红，但无永久性酒渣鼻特征。研究组间未发现显著的性别相关差异。总之，根据 NRSEC，年龄>or=30 岁人群中酒渣鼻比之前认为的更为常见。
