Dairy products and metabolic syndrome among Iranian adult population: Isfahan Healthy Heart Program

The associations between frequency of low fat, high fat and total dairy consumption and metabolic syndrome (MS) occurrence were determined. In a cross-sectional survey, 9660 randomly chosen adults aged >= 19 years were selected in three districts of central Iran in 2007. Nutrition behaviours were assessed with a food frequency questionnaire. Anthropometric, blood pressure and biochemical measurement were collected. This study showed that the total dairy intake was inversely related to MS occurrence after full adjustment [odds ratio (95% confidence interval) 0.84 (0.70-0.96); P = 0.04]. However, there were no significant associations between low and high fat dairy and the occurrence of MS after full adjustment. Total dairy intake had an inverse association with systolic blood pressure, waist circumference and triglyceride and positive relationship with high-density lipoprotein cholesterol. Further well-designed randomised clinical trials on the effect of a variety of dairy products on MS need to be conducted. (C) 2020 Published by Elsevier Ltd.
