The Relationships between Leptin, Genotype, and Chinese Medicine Body Constitution for Obesity

Abstract

Methods The adults with body mass index (BMI) more than 27\u2009kg/m2 were enrolled in the study. General personal information, physical condition, TCMBC, biochemical, and SNPs were collected for eligible subjects. The body constitution questionnaire (BCQ) was used to evaluate the relationships between TCMBC tendency, biochemical values, and obesity-related SNPs. Results Obesity patients tended to have a yin deficiency constitution (YinDC) (n\u2009=\u200933, 66.0%); however, TCMBC in combination is not uncommon (30 subjects with more than two TCMBC in combination). For biochemical profiles, leptin was higher among patients with yang deficiency constitution (YangDC) (YangDC versus non-YangDC: 29.7\u2009±\u200924.8 versus 15.9\u2009±\u20099.9, P=0.020) and YinDC (YinDC versus non-YinDC: 28.8\u2009±\u200923.5 versus 14.4\u2009±\u20099.6, P=0.020). The leptin level was highest among YangDC subjects. Higher leptin was found among subjects with three-combined TCMBC than balanced TCMBC subjects who were not inclined to any of three TCMBC. For obesity-related SNPs, the adrenergic receptor beta-3 (ADRB3) gene tended to be high expression among YangDC (YangDC versus non-YangDC: 89.7% versus 71.4%, P=0.091) and uncoupling protein 1 (UCP1) tended to be high expression among phlegm-stasis constitution (PSC) (PSC versus non-PSC: 37.9% versus 9.5%, P=0.052). Conclusions The relationships between TCMBC, leptin, and SNPs present alternative viewpoints about TCMBC and could be used as a guide to treat obese patients.
