ABSTRACT
Objectives: The goal of this cross-sectional study was to assess whether habitual coffee consumption shows beneficial association with metabolic syndrome (MetS) in adults. Methods: The association of coffee consumption and MetS-related biomarkers including visceral fat area (VFA) and subcutaneous fat area (SFA), total serum adiponectin (T-Ad), low-molecular-weight serum adiponectin (LMW-AD), medium-molecular-weight serum adiponectin (MMW-Ad), and high-molecular-weight serum adiponectin (HMW-Ad) levels were analyzed among 364 Japanese men (36–61 y old) using two models of multivariate regression analyses; model 1 (adjusted for age, alcohol drinking, smoking, and walking status) and model 2 (adjusted for body mass index in addition to model 1 analysis). Participants were categorized into two groups according to their MetS risk score (raised blood pressure and hemoglobin A1c levels, and reduced high-density lipoprotein cholesterol levels). Results: Both light (1–3 cups/d) and moderate (>4 cups/d) coffee consumption showed significant inverse associations with VFA and VFA/SFA ratio (P < 0.0001). Moderate coffee consumption showed a favorable tendency toward these associations with T-Ad (P = 0.06) and HMW-Ad (P =0.07) levels in model 1 analysis. In participants with lower MetS risk score (<1), moderate coffee consumption showed significant associations with T-Ad and HMW-Ad levels (P < 0.05) in both analyses, whereas no significant associations of coffee consumption with adiponectin levels were seen in the men with higher MetS risk scores (>2). Conclusions: Habitual moderate coffee consumption shows significant inverse associations with MetS-related biomarkers possibly involving adiponectin, which is inversely related to visceral fat accumulation.
