Introduction: Since patients with vitiligo are believed to be more susceptible to developing
malignant neoplasias due to the lack of melanin in the affected skin, the use of sunscreens
is critically important.
Objective: To evaluate the pattern of sunscreen usage in vitiligo patients.
Methods: A transverse study of vitiligo patients was conducted from August 2009 to
April 2010. The following variables were studied using a questionnaire and physical
examination: demographic data (gender, age, education level, and phototype); clinical
characteristics of the condition (age at diagnosis, affected areas of the body, and clinical
type); sunscreen use (frequency, protection factor, and duration of use); and habits of sun
exposure.
Results: Of the 121 study subjects, 43 used sunscreen – mainly with sun protection factor
30 – on a daily basis.The variables associated with daily use were female gender (p
= 0.001, OR = 4.76, 95% CI = 1.80-12.59) and recommendation by a dermatologist in
the first medical visit (p = 0.047, OR=2.28, 95% CI = 1.01-5.28).
Conclusion: A pattern of sunscreen usage was determined for patients with vitiligo. In
addition, it was verified that a dermatologist''''''''s recommendation to wear sunscreen had a
statistically significant impact (p = 0.047, OR=2.28, 95% CI = 1.01-5.28).
