Body volume by three-dimensional body scanning (3DBS) may be an alternative index for evaluating body fatness. The aim of this study was to evaluate the association of body volume with body fatness and metabolic syndrome. This study included 38 Korean women whose body volume was measured using 3DBS. We measured body fatness using dual-energy X-ray absorptiometry and computed tomography. Participants with metabolic syndrome were defined as having three or more of the following components: high blood pressure (≥130/85 mmHg), elevated fasting glucose (≥100 mg/dl), hypertriglyceridemia (≥150 mg/dl), low high-density lipoprotein-cholesterol (<50 mg/dl), and abdominal obesity measured by waist circumference ≥80 cm. Total body, trunk, lower trunk, and limb volumes were significantly correlated with body mass index, waist circumference, total fat mass, percentage body fat, and abdominal fat areas. After adjustment for age, current smoking, at-risk drinking, and physical inactivity, the odds ratios (95% confidence intervals) for metabolic syndrome associated with total body, trunk, lower trunk, and limb volume were 1.08 (1.01-1.16), 1.11 (1.01-1.22), 1.20 (1.01-1.43), and 1.31 (1.04-1.66), respectively. Body volume by 3DBS was significantly associated with body fatness and metabolic syndrome. 3DBS may be a useful tool for detecting and monitoring body fatness and metabolic syndrome.
