| Popis: | Unlike in Europeans and Africans, the relationship between the human guanine nucleotide binding beta polypeptide 3 (GNB3) C825T gene polymorphism (rs5443) and blood pressures is inconsistent in Asians. The aim of the study was to investigate whether the GNB3 genotype demonstrates different associations with resting blood pressure and body fatness across cardio/respiratory fitness (CRF) levels. A total of 727 Korean women aged 31-60 years (mean, 47.8+/-5.4 years) participated in the study. In subgroup analyses of the obese group, TT individuals had significantly higher values of body weight than CC and CT individuals (p=0.006 and p=0.006, respectively) and body mass index (BMI) (p=0.002 and p=0.011, respectively). TT and CT individuals also tended to have higher CRF values than CC individuals. Regression analyses showed that the association between GNB3 genotype and resting blood pressure remained significant after adjustment for age and menopause, but was not significant after additional adjustment for body fatness. In summary, the findings of this study suggest that body fatness and CRF might modify the GNB3-mediated genetic susceptibility to elevated resting blood pressures in middle-aged Korean women. |
