title: Prevalence of dyslipidemia among Iranian patients with idiopathic tinnitus.
abstract: BACKGROUND
  Tinnitus is a sense of sound perception in absence of an external source which can affect life quality. Different conditions may lead to tinnitus including metabolic disorders such as dyslipidemia. The aim of this study was to investigate the prevalence of dyslipidemia among Iranian patients with idiopathic tinnitus.
  
  
  METHODS
  This was a cross-sectional study in which prevalence of dyslipidemia in fasting state and its subclasses were assessed in 1043 tinnitus patients aged 12-90 years who referred to Rasool Akram Hospital, Tehran, Iran, 2006-2009. Data was summarized by SPSS software version 17 and one sample t-test and Chi-Square test were applied to analyze the results. P less than 0.05 were considered significant.
  
  
  RESULTS
  The most prevalent type of dyslipidemia was hypercholesterolemia with the frequency of 14.4% followed by low HDL-C with the frequency of 12.8%. Mean of total cholesterol, HDL-C, LDL-C and triglyceride levels in all patients were not greater than general population.
  
  
  CONCLUSIONS
  Based on the results of the present study, there might be no need to check the serum lipid profile in tinnitus patients. We recommend further studies to assess both fasting and postprandial serum lipid profile in patients with idiopathic tinnitus. Simultaneous investigation of their dietary intake is also suggested.
