Correlation of waist-hip ratio, vascular elasticity and adiposity

Objective To explore the influence of elderly waist-hip ratio (WHpR) on adiposity and vascular elasticity. Methods A total of 120 healthy middle aged and elderly people aged 40-60 years old were selected between February, 2015 and December, 2015. A number of 60 patients with normal ratio of WHpR were treated as a control group, while another 60 patients with higher ratio of WHpR as study group. Adiposity, arterial blood vessel elasticity, blood pressure, blood fat and blood glucose of two groups were compared. Results Normal rate of body fat and arterial blood vessel of the study group were lower than those of the control group. Adiposity, pulse wave velocity(PWV), body mass index of the study group were significantly higher than those of the control group. Systolic blood pressure, diastolic blood pressure, pulse pressure, blood glucose, uric acid, three acyl glycerin, total cholesterol, low-density lipoprotein cholesterol of the study group were higher than those of the control group, high density lipoprotein cholesterol was lower than that of the control group(P<0.05). WHpR was positively associated with Adiposity, degree of elastic stiffness of blood vessels and body mass index (r=0.135, P=0.011; r=0.189, P=0.013; r=0.146, P=0.014). Degree of elastic stiffness of blood vessels was positively related with WHpR, adiposity, body mass index (r=0.189, P=0.013; r=0.123, P=0.009; r=0.097, P=0.021). Conclusions WHpR can be used as an early evaluation index of Adiposity and blood vessel elasticity for middle aged and elderly people.
