Correlation between Vitiligo Severity and Dermatology Life Quality Index (DLQI) in Vitiligo Patients Undergoing Phototherapy at Bali Mandara General Hospital

Introduction: Vitiligo is an autoimmune disease characterized by macule and patch depigmentation with various shaped cause by melanocyte destruction or loss of skin function. Global prevalence of vitiligo ranges from 0,5% to 2%. The Vitiligo Area Scoring Index 9VAS) is a quantitative method for assessing the severity of vitiligo by assessing the extent of lesions based on body surface area. Patients with vitiligo often experience psychological impacts, resulting reduce quality of life. A commonly used measure of quality of life is the Dermatology Life Quality Index (DLQI) questionnaire. Objectives: to determine the correlation between vitiligo severity and the quality-of-life index in vitiligo patients undergoing phototherapy. Material and methods: An observational analytical study was conducted at the Spectra Polyclinic, Bali Mandara Regional General Hospital, Denpasar, from June to July 2025. The study subjects were 66 vitiligo patients (36 men and 30 women). The VASI score and DLQI were then measured. Data normality was tested using the Kolmogorov-Smirnov test, followed by a Fisher's Exact correlation test (p<0.05). Results: VASI score dominated by mild severity (97%), with the highest quality of life index being mildly affected (39.4%). The correlation test showed no significant correlation (p=0.248). Conclusion: The severity of vitiligo can affect the psychosocial well-being and appearance of vitiligo patients, thus affecting their quality of life, but this depends on the area of lesion involved.
