Abstract

Background: Most studies have investigated the association between dietary pattern and risk of metabolic syndrome. Limited studies have examined the association between nuts and legumes as a food group and metabolic syndrome. This study explored the association between nuts and legumes and components of metabolic syndrome in Iranian nurses. Methods: This cross-sectional study included a representative sample of 420 female nurses of Isfahan who were randomly selected. Nuts and legumes consumption was assessed using a validated dish-based semi quantitative food frequency questionnaire (FFQ). Metabolic syndrome was defined by the National Cholesterol Education Program's Adult Treatment Panel III (ATP III). Linear and logistic regression tests were used to study the association between nuts and legumes consumption and metabolic syndrome and its components. Results: Mean age of study participants was 35 years. The prevalence of the metabolic syndrome among study participants was 3.6%. Consumption of nuts and legumes was not associated with waist circumference either before (β = −0.01, P = 0.24) or after adjusting for potential confounders (β = −0.18, P = 0.41). The same findings were also observed for diastolic blood pressure (DBP) (β = 0.001, P = 0.42), serum triglyceride (TG) (β = 0.07, P = 0.32), high-density lipoprotein cholesterol (HDL-C) (β = 0.008, P = 0.65) and fasting blood sugar (FBS) (β = −0.001, P = 0.94). We failed to find a significant association between consumption of nuts and legumes and systolic blood pressure (SBP) after adjusting for confounders (β = 0.002, P = 0.38). Individuals in the highest category of nuts and legume consumption did not had elevated odds for metabolic syndrome after adjusting for potential confounders (OR = 0.89, 95% CI = 0.08–9.80, P = 0.93). Conclusions: Nuts and legumes consumption was not associated with metabolic syndrome or its components. Prospective studies are needed to investigate further this association. © 2021 European Society for Clinical Nutrition and Metabolism
