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

OBJECTIVES

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.
