Objective: To investigate the clinical epidemiology of vitiligo patients in Xinghualing District of Taiyuan City, and to analyze the influencing factors. Methods: From June 2020 to June 2021, 1440 eligible permanent residents from 10 streets under the jurisdiction of Xinghualing District, Taiyuan City were selected by multi-stage stratified random sampling method, 1428 of which were actually investigated, with a response rate of 99.17%. The questionnaire designed by our hospital was used to inquire and record the epidemiological information and clinical characteristics of all the respondents in detail. The subjects were divided into vitiligo group (n=31) and non-vitiligo group (n=1397) according to whether they had vitiligo. The influencing factors of vitiligo patients in Xinghualing District of Taiyuan City were analyzed by univariate and multivariate Logistic regression analysis. Results: Among 1428 residents included, 31 patients were diagnosed with vitiligo, with a prevalence rate of 2.17%. Among the 31 vitiligo patients, the proportion of male was higher than that of female, accounting for 54.84%. The prevalence was highest in the age range of 21～40 years, accounting for29.04%. Unmarried vitiligo patients tend to be more, accounted for 45.17%. The incidence of vitiligo was higher in middle and high school students with education level, accounting for 41.94%. The incidence of vitiligo in students was high, accounting for 32.27%.Univariate analysis showed that the occurrence of vitiligo in Xinghualing District of Taiyuan City was associated with family history of vitiligo, mental factors, history of sun exposure, drinking history, smoking history, frequent exposure to chemical substances, dietary rules, intake of fruits and vegetables, reasonable diet, and skin history (P＜0.05). Multivariate Logistic regression analysis showed that drinking history, family history of vitiligo, history of skin diseases, frequent exposure to chemicals, history of exposure to sun, and mental factors were the potential independent risk factors for vitiligo, while reasonable diet, large intake of vegetables and fruits, and regular diet were the protective factors (P＜0.05). Conclusion: The incidence of vitiligo is high in Xinghualing District, Taiyuan City. The history of alcohol consumption, family history of vitiligo, history of skin diseases, frequent exposure to chemicals, history of sun exposure, and mental factors are the potential independent risk factors for vitiligo, while reasonable diet, large intake of vegetables and fruits, and dietary laws are the protective factors.
