Phase angle (PhA) is linked to waist circumference in adults. Lower PhA indicates greater waist circumference, suggesting PhA may serve as a cardiometabolic biomarker.
Area of Science:
- Biomarkers
- Metabolic Health
- Human Physiology
Background:
- The phase angle (PhA) is a measure derived from bioelectrical impedance analysis.
- Metabolic syndrome is a cluster of conditions that increase the risk of heart disease, stroke, and type 2 diabetes.
- Understanding biomarkers for cardiometabolic risk is crucial for public health.
Purpose of the Study:
- To investigate the association between phase angle (PhA) and various metabolic profile components in adults.
- To determine if PhA can serve as a potential biomarker for cardiometabolic risk.
Main Methods:
- Cross-sectional, population-based study of 949 adults aged 20-59.
- Phase angle (PhA) measured using electrical bioimpedance analysis.
- Metabolic profile included waist circumference, glucose, lipids, CRP, HOMA-IR, uric acid, and blood pressure; analyzed using linear regression.
Main Results:
- Increased waist circumference was significantly associated with lower phase angle (PhA) values (β: -0.01; 95% CI: -0.03 to -0.01).
- No significant association was found between PhA and glucose, non-HDL-C, triglycerides, CRP, HOMA-IR, or uric acid in adjusted models.
Conclusions:
- Low phase angle (PhA) is directly associated with increased waist circumference in adults, independent of sociodemographic, lifestyle, and BMI adjustments.
- Phase angle (PhA) shows promise as a valuable biomarker for assessing cardiometabolic health in adults.
