Objective To investigate augmentation index (AIx) and the affecting factors in Xinjiang Uygur health adults.
Methods The total of 2366 Uygur natural adults were investigated. 559 health adults (male 251, female 308) were selected in the study and the mean age was (44.95±11.87) years. All the subjects were measured the following indexes: questionnaire, physical examination, fasting blood glucose, blood lipid, renal function and C-reactive protein (CRP). Central systolic blood pressure (cSBP) and central augmentation index (AIx) were measured by Sphygmocor.
Results AIx in female was higher than in male (male: 18.52±11.27, female: 29.84±8.44, p<0.05). The same result was found in different age groups. Unadjusted correlation analysis showed AIx was positively related to age in both genders (male: r=0.548, female=0.405, p<0.05), as well as adjusted other influential factors (male: r=0.182, female=0.234, p<0.05). Multivariate regression analysis showed that cSBP, systolic blood pressure (SBP), age, weight and CRP were main factors which affected AIx in male, while age, cSBP, SBP, height and CRP were main factors which affected AIx in female.
Conclusion AIx in female was higher than in male. AIx was positively related to age in both genders. Age, cSBP, SBP and CRP were main factors affected AIx in Xinjiang Uygur health adults.
