title: Differences in the lipid profile and hormone replacement therapy use in Korean postmenopausal women: the Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012.
abstract: Hormonal changes after menopause can cause dyslipidemia by the cessation of endogenous estrogen. We analyzed the lipid profile of the Korean healthy menopausal women according to the use of hormone replacement therapy (HRT).
  
  
  
  Data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012 were analyzed. The study included 428 healthy postmenopausal women with HRT (HRT group) and 1804 healthy postmenopausal women without HRT (NHRT group).
  
  
  
  After adjustment for confounding factors, total cholesterol (TC) and low-density lipoprotein (LDL) were lower in the HRT group than in the NHRT group (TC: 200.1 ± 2.0 vs. 204.9 ± 1.1, P = 0.04; LDL: 120.3 ± 1.0 vs. 124.5 ± 1.0 mg/ml, P = 0.033). Triglycerides (TG) were lower in the HRT group than in the NHRT group [106.8, (95 % CI 99.8-114.3) vs. 115.1 (95 % CI 111.8-118.5), P = 0.04]. Non-high-density lipoprotein (HDL) was lower in the HRT group than in the NHRT group (145.4 ± 1.9 vs. 151.2 ± 1.0 mg/ml, P = 0.008). Patients with HRT were lower in the LDL cholesterol level (OR 0.601, 95 % CI 0.397-0.917, P = 0.018), the total cholesterol to high-density lipoprotein ratio (OR 0.787, 95 % CI 0.617-0.997, P = 0.016), and the non-HDL level (OR 0.68, 95 % CI 0.509-0.907, P = 0.009).
  
  
  
  The results of this study suggest that the use of HRT may have a positive effect on dyslipidemia in postmenopausal women.
