Relationship of abdominal obesity with circadian blood pressure rhythm and arterial stiffness in elderly women
Abstract：Objective To study the relationship of abdominal obesity with circadian blood pressure rhythm and arterial stiffness in elderly women .Methods Three hundred and fifty-three elderly women were divided into non-abdominal obesity group (n= 160) and abdominal obesity group (n=193)according to their waist circumference .Their carotid radial pulse wave velocity(crPWV) and 24 h ambulatory blood pressure were monitored .Results The non-dipper blood pressure , crPWV and symmetric AASI were significantly higher in abdominal obesity group than in non-abdominal obesity group (32 .6% vs 10 .0% ,11 .83 ± 1 .19 m/s vs 10 .90 ± 1 .04 m/s ,0 .31 ± 0 .15 vs 0 .24 ± 0 .17 ,P<0 .05) wile the nocturnal systolic and diastolic blood pressure were significantly lower in abdominal obesity group than in non-abdominal obesity group (P<0 .01) .Multiple linear regression analysis showed that waist circumference was the main risk factor for crPWV and sym-metric AASI after adjustment for age ,blood lipid and BMI (P<0 .05) .Logistic regression analysis revealed that abdominal obesity was the main risk factor for circadian blood pressure rhythm (OR=1 .104 ,95% CI:1 .074 -1 .134 ,P<0 .05) .Conclusion Abdominal fat deposit can signifi-cantly affect circadian blood pressure rhythm and arterial stiffness in elderly women .It is of great importance to control waist circumference in preventing arteriosclerosis .
