A nationwide study of 27,565 Korean adults evaluated whether the metabolic score for visceral fat (METS-VF) outperforms traditional metrics like BMI in detecting hypertension risk. Participants in the highest third of METS-VF scores showed a 2.76-fold increased risk of hypertension compared to the lowest third after rigorous confounder adjustments. METS-VF significantly eclipsed traditional body mass index, waist circumference, and lipid accumulation scores in diagnostic accuracy. Crucially, the strongest relative danger was observed among individuals categorized as normal weight, proving that metabolic dysfunction from visceral adiposity operates independently of total body scale weight.
Standard scales and measuring tapes often misclassify metabolic disease risk. Clinicians and patients frequently rely on body mass index to assess cardiovascular and metabolic fitness, yet body weight alone fails to differentiate healthy lean tissue from pathologically active internal fat. This national cross-sectional analysis of 27,565 South Korean adults investigated whether an advanced computational index, the metabolic score for visceral fat (METS-VF), provides superior diagnostic accuracy for hypertension compared to traditional anthropometric measures.
The score integrates routine laboratory blood markers including fasting glucose, triglycerides, and high-density lipoprotein with waist-to-height ratio, sex, and age. When dividing the population into tertiles, researchers identified an escalation in high blood pressure prevalence, climbing from 2.3 percent in the lowest tertile to 22.7 percent in the highest. After fully adjusting for age, sex, BMI, tobacco use, alcohol intake, physical activity, and baseline inflammatory white blood cell count, individuals in the highest tertile retained nearly a three-fold higher odds of hypertension.
The critical revelation of this investigation lies in who faces the steepest relative risk. When investigators stratified the population by body weight classification, the association between elevated METS-VF and hypertension was most severe among normal-weight adults, who demonstrated a 2.44-fold increase in odds. In contrast, the association attenuated in overweight individuals. This finding reinforces the physiological hazard of normal-weight visceral obesity, sometimes described as metabolically obese normal-weight phenotype. Individuals who appear lean externally may still silently accumulate deep intra-abdominal fat surrounding vital organs. This visceral adipose tissue acts as an inflammatory organ, generating vascular tension, renal compression, and endothelial dysfunction.
Receiver operating characteristic curve comparisons demonstrated that METS-VF achieved an area under the curve of 0.747, substantially outperforming traditional BMI at 0.625, waist circumference at 0.664, and earlier lipid markers such as the visceral adiposity index at 0.577. By incorporating circulating metabolic factors directly into an adiposity score, METS-VF converts routine clinical tests into an early detection system for subclinical vascular dysfunction before overt systemic hypertension becomes clinically entrenched.
Actionable Insights
Body mass index alone is insufficient to clear someone of high blood pressure risk. Individuals possessing normal body weight can harbor dangerous amounts of deep visceral fat that strain arteries.
-
Monitor Visceral Fat Surrogates: Instead of relying purely on a bathroom scale, calculate METS-VF or monitor the METS-IR sub-score using routine fasting blood panels (fasting glucose, triglycerides, and HDL cholesterol) combined with waist-to-height ratio.
-
Quantified Real-World Effect Size: Transitioning from the lowest metabolic visceral fat tier to the highest elevates hypertension prevalence from 2.3 percent to 22.7 percent, representing a 20.4 percentage point absolute risk increase and an unadjusted relative risk increase of 887 percent. After multivariable adjustment controlling for total BMI and lifestyle factors, the adjusted odds ratio remains 2.76, demonstrating a nearly 180 percent expansion in odds. For continuous tracking, each single 1-point increase in the METS-VF score multiplies the odds of hypertension by 3.99.
-
Targeted Intervention: Individuals showing elevated visceral fat scores despite a normal BMI must treat visceral adiposity through targeted lifestyle modifications, including high-intensity interval training, resistance conditioning to preserve muscle glucose sinks, restriction of refined sugars, and nutritional strategies that suppress hepatic de novo lipogenesis.
