Abstract

BACKGROUND: Epidemiologic studies have shown an inverse association between dietary fiber and metabolic syndrome (MetS). Therefore, the purpose of this study was to investigate the association between MetS and consumption of legumes in adults in Isfahan, Iran. METHODS: This cross-sectional study was carried out on 2027 individuals who were a subsample of the 3rd phase of the Isfahan Healthy Heart Program (IHHP). Basic characteristics information such as age, sex, smoking status, and physical activity were collected using a questionnaire. A validated 48-item food frequency questionnaire was used to assess dietary behaviors. Blood pressure, waist circumference (WC), glucose, triacylglycerols, and high-density lipoprotein cholesterol were measured, and MetS was defined based on Adult Treatment Panel III guidelines. Multiple logistic regression models examined associations of frequency consumption of legumes with MetS occurrence and its components. RESULTS: All MetS components were less prevalent among subjects with regular legume intake (P < 0.01). Legume intake was inversely associated with the risk of MetS, after adjustment for confounding factors in women. Life style adjusted odds ratio of Mets between highest and lowest tertile and no consumption (as reference category) of legume intake were 0.31 (0.13, 0.70), 0.38 (0.17, 0.87), respectively, in women (P = 0.01). CONCLUSION: This study showed that age has a crucial role in MetS incidence; therefore, after further age adjustment to lifestyle adjusted model there was no significant difference in lower and higher tertile of legume intake and MetS.
