The Relationship Between Arterial Stiffness, Anthropometry, and Body Composition in Middle-Aged Individuals: A Cross-Sectional Study.

CAVI showed significant positive correlations with multiple anthropometric indices and visceral fat level.

• CAVI correlated positively with BMI (r = 0.201, p = 0.013), WC (r = 0.315, p < 0.001), and WHR (r = 0.226, p = 0.005)
• CAVI also correlated positively with ABSI (r = 0.172, p = 0.033), AVI (r = 0.313, p < 0.001), BRI (r = 0.249, p = 0.002), and CI (r = 0.255, p = 0.001)
• Visceral fat level showed a significant positive correlation with CAVI (r = 0.289, p < 0.001)
• BAI was not listed among the significant correlates of CAVI

Linear regression confirmed independent associations between CAVI and both muscle mass and visceral fat levels.

• Muscle mass was negatively associated with CAVI (β = -0.559, p = 0.035), indicating higher muscle mass was linked to lower arterial stiffness
• Visceral fat level was positively associated with CAVI (β = 0.470, p = 0.010), indicating higher visceral fat was linked to greater arterial stiffness
• These associations were confirmed via linear regression analysis

High WC and WHR, but not BMI or body fat percentage, were significantly associated with arterial stiffness after covariate adjustment.

• WC and WHR were significantly associated with high CAVI after adjusting for age, gender, and hypertension
• BMI was not significantly associated with arterial stiffness after adjustment
• Percentage body fat (%BF) was not significantly associated with arterial stiffness after adjustment
• This suggests that abdominal obesity indices are more informative than general obesity measures for arterial stiffness risk

The study was conducted in 153 middle-aged Thai adults categorized into low and high arterial stiffness groups using CAVI.

• Total sample size was 153 participants in a cross-sectional design
• Participants were categorized into low-CAVI (CAVI < 9.0) and high-CAVI (CAVI ≥ 9.0) groups
• Both traditional anthropometric indices (BMI, WC, WHR) and novel indices (ABSI, AVI, BAI, BRI, CI) were assessed
• Body composition including %BF, muscle mass, and visceral fat levels was measured via bioelectrical impedance analysis

The association between abdominal obesity and arterial stiffness was identified as controversial in existing literature, motivating this investigation.

• The authors noted that 'the association between abdominal obesity and arterial stiffness remains controversial'
• The study aimed to investigate associations among anthropometric indices, body composition, and arterial stiffness specifically in middle-aged Thai adults
• Both traditional and novel anthropometric indices were included to provide a comprehensive assessment
