title: The sasang constitution as an independent risk factor for metabolic syndrome: propensity matching analysis.
abstract: THE SASANG CONSTITUTIONAL MEDICINE IS A TRADITIONAL KOREAN CUSTOMIZED MEDICINE THAT CLASSIFIES PEOPLE INTO FOUR TYPES: Tae-eumin (TE), Soyangin (SY), Soeumin (SE), and Taeyangin. The aim of this study was to show whether the Sasang Constitution (SC) could be an independent risk factor for the metabolic syndrome (MS). Totally, 3,334 subjects from 24 Korean medicine clinics participated in this study. A one-way ANOVA for the continuous variables and a chi-square test for the prevalence of MS were conducted. A logistic regression was conducted to calculate the propensity score and the odds ratios (ORs). The prevalence for MS in TE, SY, and SE was 50.6%, 30.9%, and 17.7% (P < 0.001) before matching, and 36.7%, 28.6% and 28.2% (P = 0.042) after matching, respectively. The TE was associated with an increased OR for MS compared with the SE and SY in both crude (OR 4.773, 95% CI 3.889-5.859, and OR 2.292, 95% CI 1.942-2.704, resp.) and matched groups (OR 1.476, 95% CI 1.043-2.089, and OR 1.452, 95% CI 1.026-2.053, resp.). This study reveals that the SC, especially the TE type, could be considered as a risk element for MS even in people with otherwise similar physical characteristics.
