title: Plasma lipid peroxides: relationships to cardiovascular risk factors and prevalent cardiovascular disease.
abstract: BACKGROUND
  The epidemiology of plasma lipid peroxides, which may play a role in atherogenesis, has not been well defined.
  
  
  OBJECTIVE
  To study the relationships of plasma lipid peroxides to cardiovascular risk factors in a random population sample.
  
  
  METHODS
  Random, age- and sex-stratified population sample.
  
  
  METHODS
  We studied 739 men and women aged 25-74 years. Lipid peroxides were assayed by the thiobarbituric acid (TBA) assay for malondialdehyde (MDA) in stored plasma samples.
  
  
  RESULTS
  Lipid peroxide levels increased with age. In men, lipid peroxides were significantly associated with smoking habit. Lipid peroxides correlated with non-fasting serum triglycerides (r = 0.33; p < 0.0001) in both sexes. Weaker associations were observed for cholesterol, high-density lipoprotein cholesterol (inversely), body mass index, fibrinogen and white cell count; as well as an inverse association with serum vitamin C in men.
  
  
  CONCLUSIONS
  These findings clarify the relationships of plasma lipid peroxides to cardiovascular risk factors; and are consistent with the hypothesis that lipid peroxidation may be one mechanism through which several risk factors may promote cardiovascular disease.
