Relationship between the incidence of rosacea and drinking or smoking in China.

To explore the relationship between the incidence of rosacea and drinking, smoking, gender or age, and to provide some basis for the diagnosis, treatment and mechanism of rosacea.A total of 1 180 patients with rosacea and 1 008 non-rosacea patients diagnosed in the Department of Dermatology of Xiangya Hospital were included in the study. Logistic analysis was performed on the incidence factors, and the differences between the two groups in different age groups were compared.There was no significant difference in gender between the two groups (P>0.05). Logistic analysis showed that drinking had no effect on the incidence of rosacea (P>0.05); while smoking, gender, and age had an effect on the incidence of rosacea (P<0.05). The highest proportion of patients with rosacea was 25-34 years old.The incidence of rosacea has nothing to do with alcohol consumption; while smoking, gender, and age affect the incidence. Smoking and women are the risk factors, and the most common age of rosacea is at 25-34 years old.目的: 探讨玫瑰痤疮的发病与饮酒、吸烟、性别及年龄的关系，为玫瑰痤疮的诊治及机制探讨提供一定依据。方法: 收集在中南大学湘雅医院皮肤科就诊并诊断为玫瑰痤疮的患者1 180例，同时收集非玫瑰痤疮患者 1 008例作为对照，对两组玫瑰痤疮发病因素进行logistic回归分析，并进一步比较两组不同年龄组之间的差异。结果: 两组性别间比较差异无统计学意义(P>0.05)。logistic回归分析显示饮酒对玫瑰痤疮的发病无影响(P>0.05)；抽烟、性别、年龄对玫瑰痤疮发病有影响(P<0.05)。25~34岁年龄段的玫瑰痤疮患者占比最高。结论: 玫瑰痤疮的发病与饮酒无关；而吸烟、性别和年龄对其发病率有影响，其中抽烟、女性为危险因素，玫瑰痤疮最多发年龄在25~34岁。.
