Abstract
<b><i>Introduction:</i></b> A body shape index (ABSI) is an anthropometric index designed to reflect the influence of visceral fat. ABSI has been previously associated with various atherosclerosis, metabolic diseases, and cardiovascular diseases; however, relatively few studies have been conducted on cerebrovascular disease. In this study, we evaluated the association between ABSI and cerebral small vessel disease (cSVD) in health check-up participants. <b><i>Methods:</i></b> We evaluated consecutive health check-up participants between January 2006 and December 2013. As subtypes of cSVD, we quantitatively measured the volume of white matter hyperintensity (WMH) and qualitatively measured the presence of silent brain infarct (SBI) and cerebral microbleed (CMB). ABSI was calculated according to the following formula: ABSI (m<sup>11/6</sup>/kg<sup>−2/3</sup>) = waist circumference (m)/(body mass index [kg/m<sup>2</sup>]<sup>2/3</sup> × height [m]<sup>1/2</sup>). <b><i>Results:</i></b> A total of 3,219 health check-up participants were assessed (median age, 56 years; male sex, 54.0%). In the multivariable analysis, ABSI was significantly associated with WMH volume (β = 0.107, 95% confidence interval [CI] = 0.013–0.200), SBI (adjusted odds ratio [aOR] = 1.62, 95% CI = 1.14–2.31), and CMB (aOR = 1.64, 95% CI = 1.16–2.33) after adjusting for confounders (per 100 m<sup>11/6</sup>/kg<sup>−2/3</sup>). Furthermore, ABSI showed a dose-response relationship with the burden of each cSVD pathology. <b><i>Conclusions:</i></b> High ABSI was associated with a higher burden of cSVD in health check-up participants. As ABSI showed close associations with all subtypes of cSVD, visceral fat may be a common risk factor penetrating cSVD pathologies.
