Key result
ABSI-defined metabolic syndrome is linked to ~69% higher odds of arterial stiffness versus standard criteria.
Why the study?
Cardio-ankle vascular index (CAVI) is unexpectedly not always high in metabolic syndrome (MetS) patients and correlates negatively with waist circumference (WC), raising questions about using WC to define MetS.
Does replacing waist circumference with A Body Shape Index (ABSI) in the diagnosis of metabolic syndrome improve the identification of individuals with increased cardio-ankle vascular index (CAVI) and risk of renal function decline in Japanese and Korean populations?
Does replacing waist circumference with A Body Shape Index (ABSI) in the diagnosis of metabolic syndrome improve the identification of individuals with increased cardio-ankle vascular index (CAVI) and risk of renal function decline in Japanese and Korean populations?
Replacing waist circumference with A Body Shape Index (ABSI >= 0.080) in metabolic syndrome diagnostic criteria improves the identification of patients with increased arterial stiffness (CAVI) and higher risk of future renal function decline in East Asian populations.
ABSI substitution in MetS criteria may better flag arterial stiffness and renal risk in East Asians; leaves open prospective validation before practice change.
Obesity has been known to relate to various diseases and metabolic disorders. Since the implication of body shape has been mentioned, obesity can be divided into visceral obesity and subcutaneous obesity. The former is considered the upstream pathophysiology of metabolic syndrome (MetS), and has been emphasized worldwide for the prevention of cardiovascular diseases in the last quarter century. However, some prospective studies have shown that cardiovascular mortality and morbidity are not necessarily higher in patients with MetS compared to those without. Recently, cardio-ankle vascular index (CAVI) has been established as an indicator of arteriosclerosis. This parameter is independent of blood pressure at the measuring time, and reflects systemic arterial stiffness from the aortic origin to the ankle. However, since CAVI is not necessarily high in MetS patients, attempts have been made to clarify this unexpected phenomenon. In several studies, CAVI was found to correlate negatively with body mass index (BMI), and also with waist circumference (WC) which is a widely used representative visceral obesity index. On the other hand, a body shape index (ABSI) is also a visceral obesity index designed to be minimally associated with BMI, and is calculated by dividing WC by an allometric regression of weight and height. Replacing high WC with high ABSI in MetS diagnosis promoted the identification of MetS patients with increased CAVI in cross-sectional studies on Japanese and Korean populations. Additionally, the incidence of MetS diagnosed using high ABSI was associated with significant increase in CAVI after 1 year of observation. Enhanced predictive ability for renal function decline by replacing WC with ABSI in MetS diagnosis was also observed in a longitudinal study in Japanese urban residents. These findings suggest that MetS diagnosis using high ABSI instead of high WC as a visceral obesity index needs to be reconsidered. However, further research is desirable on Caucasian, whose body shape differs slightly from that of Asians.

Nagayama et al. (2022) conducted a review in Metabolic syndrome and arterial stiffness. A Body Shape Index (ABSI) >= 0.080 in metabolic syndrome diagnosis vs. Conventional waist circumference (WC) in metabolic syndrome diagnosis was evaluated on Increased arterial stiffness defined as highest quartile of CAVI (in the 7,179 Korean cohort) and high CAVI >= 9.0 (in the 62,514 Japanese cohort) (OR 1.69, 95% CI 1.51-1.90, p=<0.001). Replacing waist circumference with A Body Shape Index (ABSI) in metabolic syndrome diagnosis improved identification of increased CAVI (OR 1.69, 95% CI 1.51-1.90 vs OR 1.32) and renal decline.
