Institute of Healthcare Thesis A thesis submitted to the Graduate Institute of Health Care of Meiho University In partial fulfillment of the requirement for the degree of Master of Health Care July 2015 Abstract Background: Melasma, a localized hyperpigmentation, affects millions of people worldwide The Dermatology Hospital in Ho Chi Minh city is the biggest hospital specializing in treatment of dermatological conditions, including melasma After a course of laser therapy, patients were counseled to use sunscreen to prevent the recurrence of melasma and revisit the hospital after one-month use of sunscreen to check their conditions Although no official data about the rate of recurrence among affected patients, many recurrent cases have been documented in practice Such situation raises questions involving whether or not patients used sunscreen after laser therapy, how they applied sunscreen in their daily life and to what extent they are knowledgeable about melasma and proper use of sunscreen to protect their body from recurrence of melasma Objective: The aim of the study was to find out the knowledge, attitude and behavior related to sunscreen application among melasma patients who had received laser therapy Methods: A cross-sectional hospitalized-based study is undertaken between April and May 2015 in Ho Chi Minh city, Vietnam A sample of 123 patients with melasma was collected and took part in interviews with a structured questionnaire The significance of the results was assessed by t-test, ANOVA test and Chi-Square test at p-value of 0.05 using SPSS version 16 Results: There were 123 participants enrolled in the study; of which, 80.49% was female There were 60.61% female patients had a history of pregnancy Most of participants in the study had the age from 20 to 49 years of age (87.81%) and only 1.63% of participants aged over 60 There were 63.41% patients had married, while 32.52% were unmarried Kinh was the predominant ethnic in this study (93.5%) The total knowledge mean score of participants was relative low, yielding 1.96 ± 1.09 (0-4) The total attitude score among patients was relative high (30.53 ± 4.16) The proportion of using sunscreen among participants was 78.05% The analysis showed that gender and occupation had significant associations with knowledge about sunscreen use among patients with melasma (p< 0.05) Male had lower attitude score than female and this deference was statistical significant (p< 0.001) Patients who were illiterate and finished elementary school, high school, university gain the highest score compared to other education groups (p=0.03) Between gender and sunscreen use had a significant association (p< 0.001) in which female patients practiced sunscreen use higher than male patients elative with melasma and recurrence of melasma were two factors those had statistical significant associations with behavior of sunscreen use among patients (p=0.04 and p =0.005) Conclusion: The study showed that patients with melasma had low knowledge on sun exposure and sunscreen use On the contrary, attitude and behavior of sunscreen use were relative high Gender play an important role in determining knowledge, attitude and behavior of patients Other factors including sun-exposed occupation, educational, family history of melasma and recurrence of melasma were also have influences on knowlegde, attitude and behavior of participants Thus, a education program on sunscreen use should be implimented in the near future to improve knowledge, attitude and enhance behavior of patients with melasma
