Relationship between body adiposity and arterial stiffness in young Indian adults

ABSTRACT : Obesity is one of the major cardiovascular risk factors and is linked with arterial stiffness. This study was undertaken to establish the relationship between regional adiposity and arterial stiffness using simple noninvasive techniques. Methods: In total, 181 Asian Indian adults aged 18–28 years (mean age 21.9 ± 2.2) were measured for adiposity and arterial stiffness. Total body fat percentage was derived from skinfold thickness of various body sites. Body mass index and waist‑hip‑ratio were also measured. Arterial stiffness was measured using a SphygmoCor with a carotid‑radial pulse wave analysis technique. Results: Significant gender differences were observed on anthropometric variables including skinfold thickness (P < 0.05) and all the arterial stiffness variables (P < 0.05) except pulse wave velocity. Systolic pressure, augmentation pressure, augmentation index (AIx), AIx at 75% heart rate, and aortic systolic pressure statistically significant correlations with all three adiposity variables (P < 0.05). Significant correlations were found in a higher number of variables in the females. Physical activity had negative correlations with arterial stiffness and adiposity variables (P < 0.05). : Arterial stiffness measured by carotid‑radial pulse wave analysis is strongly related to adiposity measured from skinfold thickness in females. Females had higher arterial stiffness and adiposity compared with men. These findings could be helpful in future research using noninvasive arterial stiffness measurements.
