title: [Association between peroxisome proliferator-activated receptor gene single nucleotide polymorphisms and arterial stiffness in adult Chinese population].
abstract: OBJECTIVE
  To analyze the association between single nucleotide polymorphisms (SNPs) of peroxisome proliferator-activated receptor(PPAR) and arterial stiffness in adult Chinese population (> 50 years).
  
  
  METHODS
  Cardiovascular risk factors from participants of Beijing epidemiological investigation were analyzed. Carotid-femoral pulse wave velocity (cfPWV) was measured by Complior system. The subjects were divided into normal arterial stiffness group (cfPWV < 12 m/s, n = 844) and increased arterial stiffness group (cfPWV > 12 m/s, n = 530). Three valid SNPs including rs1053049, rs1800234 and rs8192678 in the PPAR and PPARγC1a gene were genotyped by TaqMan allelic discrimination assays.
  
  
  RESULTS
  The age [(67.9 ± 8.8) years vs. (58.0 ± 9.7) years], prevalence of hypertension [71.1% (377/530) vs. 30.5% (257/844)] and diabetes mellitus [21.7% (115/530) vs. 11.0% (93/844)] were all significantly higher in increased arterial stiffness group than in normal group (all P < 0.05). The frequencies of CC, CT and TT type of rs8192678 [CC: 32.2% (272/844) vs. 30.8% (163/530), CT: 48.7% (411/844) vs. 52.1% (276/530), TT: 19.1% (161/844) vs. 17.2% (91/530)], rs1053049 [CC: 55.7% (470/844) vs. 51.3% (272/530), CT: 36.7% (310/844) vs. 39.1% (207/530), TT: 7.6% (64/844) vs. 9.6% (51/530)] and rs1800234 [CC: 88.4% (746/844) vs. 90.4% (479/530), CT + TT: 11.6% (98/844) vs. 9.6% (51/530)] were similar between the two groups. There was also no association between haplotypes and the increased arterial stiffness in this cohort.
  
  
  CONCLUSIONS
  In this community-based population, we found that aging, hypertension and diabetes mellitus were associated but SNPs of PPAR and PPARγC1a were not associated with arterial stiffness.
