title: The hypertriglyceridemia is associated with isolated impaired glucose tolerance in subjects without insulin resistance.
abstract: OBJECTIVE
  The objective of this study was to determine if hypertriglyceridemia is associated with isolated impaired glucose tolerance in subjects without insulin resistance.
  
  
  METHODS
  A total of 365 apparently healthy individuals aged 20-65 years were enrolled in a population-based cross-sectional study. Subjects were allocated into the groups with and without hypertriglyceridemia. Age, gender, body mass index, and waist circumference were matched criteria. Individuals with impaired fasting glucose, impaired fasting glucose+impaired glucose tolerance, diabetes, homeostasis model assessment of insulin resistance index ≥ 2.5, and/or chronic illnesses such as renal disease or malignancy were excluded. Hypertriglyceridemia was defined by triglycerides levels ≥ 150 mg/dL. Impaired glucose tolerance was defined by plasma glucose concentration 2-h post-load glucose ≥ 140 mg/dL <200 mg/dL. Subjects with impaired glucose tolerance were required to have fasting plasma glucose levels <100 mg/dL. Logistic regression analysis was used to compute the odds ratio between hypertriglyceridemia (independent variable) and impaired glucose tolerance (dependent variable).
  
  
  RESULTS
  A total of 132 and 233 subjects were allocated into the groups with and without hypertriglyceridemia, respectively. The frequency of impaired glucose tolerance was 13.6% and 5.6% in the individuals with and without hypertriglyceridemia, p = 0.01. The logistic regression analysis adjusted by gender, blood pressure, and high-density lipoprotein cholesterol showed that hypertriglyceridemia is significantly associated with impaired glucose tolerance (OR 2.34; 95% CI: 1.02-5.32, p = 0.04).
  
  
  CONCLUSIONS
  Results of this study indicate that hypertriglyceridemia is independently associated with isolated impaired glucose tolerance in subjects without insulin resistance.
