Association between phase angle and inflammatory blood biomarkers in community-dwelling older adults: Itabashi Longitudinal Study on Aging
Background & aim
Bioelectrical impedance analysis–derived phase angle (PhA) reflects the disruption of the cell membrane and intra- and extracellular fluid imbalances caused by chronic inflammation. This study examined the association between PhA and inflammatory markers in community-dwelling older adults.
Methods
A sex-stratified logistic regression analysis was conducted, with elevated C-reactive protein (CRP; ≥3.0 mg/L) and interleukin-6 (IL-6; >4.0 pg/mL) levels as the outcomes and whole-body and local PhAs as the exposures. The same analysis was conducted with further stratification for age, overweight status, history of inflammation-related non-communicable diseases, and dietary inflammatory index. The ability to identify inflammation in whole-body and local PhAs was assessed using a receiver operating characteristic (ROC) curve.
Results
This study included 1664 participants (age: 76 [73–80] years; 855 women). In men, significant odds ratios (ORs) at the 95 % confidence interval (95 % CI) were observed for abnormal CRP and IL-6 levels for both whole-body and leg PhAs in the third quartile compared with the lowest quartile (OR [95 % CI] for abnormal CRP levels: 0.36 [0.18, 0.68] for whole-body PhA, 0.51 [0.27, 0.95] for leg PhA; OR [95 % CI] for abnormal IL-6 levels: 0.36 [0.15, 0.81] for whole-body PhA, 0.33 [0.12, 0.78] for leg PhA). The areas under the ROC curves (95 % CI) for identifying abnormal IL-6 were mild in men (0.62 [0.54, 0.70] for whole-body PhA and 0.62 [0.55, 0.70] for leg PhA). In men without a history of inflammation-related non-communicable diseases, it was 0.72 (0.59, 0.85) for whole-body PhA and 0.68 (0.54, 0.81) for leg PhA. In women, the PhA was not significantly associated with inflammatory markers.
Conclusion
PhA is associated with inflammation in community-dwelling older men, but may need to be combined with other information to identify inflammation.
期刊介绍：
Clinical Nutrition ESPEN is an electronic-only journal and is an official publication of the European Society for Clinical Nutrition and Metabolism (ESPEN). Nutrition and nutritional care have gained wide clinical and scientific interest during the past decades. The increasing knowledge of metabolic disturbances and nutritional assessment in chronic and acute diseases has stimulated rapid advances in design, development and clinical application of nutritional support. The aims of ESPEN are to encourage the rapid diffusion of knowledge and its application in the field of clinical nutrition and metabolism. Published bimonthly, Clinical Nutrition ESPEN focuses on publishing articles on the relationship between nutrition and disease in the setting of basic science and clinical practice. Clinical Nutrition ESPEN is available to all members of ESPEN and to all subscribers of Clinical Nutrition.
