title: Clinical Characteristics and Quality of Life of Seborrheic Dermatitis Patients in a Tropical Country.
abstract: BACKGROUND
  Seborrheic dermatitis is a common chronic inflammatory skin condition that can have a negative impact on a patient's quality of life. Few studies have been conducted to assess the clinical characteristics of the disease and quality of life of the patients, especially in tropical countries.
  
  
  OBJECTIVE
  The aim of this study was to demonstrate the clinical characteristics and quality of life of patients with seborrheic dermatitis in Thailand.
  
  
  METHODS
  A cross-sectional study was performed at a university-based hospital and tertiary referral center in Bangkok, Thailand. The validated Thai version of the dermatology life quality index (DLQI) was used to evaluate patients' quality of life.
  
  
  RESULTS
  A total of 166 participants were included. One hundred and forty-seven patients (88.6%) experienced multiple episodes of the eruption. The mean of outbreaks was 7.8 times per years, ranging from once every 4 years to weekly eruption. The most common factor reported to aggravate seborrheic dermatitis was seasonality (34.9%), especially hot climate. The mean (SD) of the total DLQI score was 8.1 (6.0) with a range of 0 to 27. There was no statistically significant difference between the two DLQI categories regarding duration of disease, extent of involvement, symptoms or course of the disease.
  
  
  CONCLUSIONS
  Although mild and asymptomatic, seborrheic dermatitis can have a great impact on the quality of life. Youth, female gender, and scalp lesions were significantly associated with higher DLQI scores.
