S Hosseinpour Niazi, P Mirmiran, G Sohrab, F Hosseini Esfahani, F Azizi,
Volume 7, Issue 4 (16 2012)
Abstract

Normal 0 false false false EN-US X-NONE AR-SA Background & Objectives: There is little known about the relation between metabolic syndrome and fiber intake are available in Iran. We evaluated the relation between total, and various types and sources of dietary fiber and the prevalence of the metabolic syndrome.
Methods: In this cross sectional study, 2457 adults, aged 19-84 years were studied. Total dietary fiber intake and its types and sources were assessed using a validated semi quantitative food-frequency questionnaire. Blood pressure, Anthropometric, and biochemical measurements were assessed. The metabolic syndrome was defined according to definition by Iranian National Committee of Obesity.
Results: In the multivariate-adjusted odds ratio, intakes of total (OR: 0.53 95% CI: 0.39-0.74), both soluble
(OR: 0.60 95% CI: 0.43-0.84) and insoluble dietary fiber (OR: 0.51 95% CI: 0.35-0.72), fruit fiber
(OR: 0.51 95% CI: 0.37-0.72), legume fiber (OR: 0.73 95% CI: 0.53-0.99) and cereal fiber
(OR: 0.74 95% CI: 0.57-0.97) were inversely associated with the metabolic syndrome. There was not significant association between using vegetable and nut fiber and prevalence of metabolic syndrome.
Conclusion: Total dietary fiber, both soluble and insoluble fibers, and especially fruit and legumes fibers, reduce the metabolic syndrome among adults in Tehran.


Association of Tea, Coffee, Caffeine and Chronic Kidney Disease: Tehran Lipid and Glucose Study

Volume 18, Issue 3 (Vol.18, No.3, Autumn 2022)
Abstract
Background and Objectives: Dietary intakes are one of the factors influencing the incidence of chronic kidney disease. The present study was performed to investigate the possible long-term effects of caffeine, tea and coffee consumption on the incidence of chronic kidney disease.
Methods: 1780 adults participating in the third phase of the Tehran Lipid and Glucose Study (TLGS) (2006-2008) were selected for inclusion criteria. Dietary intakes were assessed using a food frequency questionnaire (FFQ). Demographic variables, anthropometrics, and biochemical data were measured at baseline and after six years of follow-up. To estimate the risk of chronic kidney disease, logistic regression analysis, adjusted for possible confounding variables, was used.
Results: Participants’ mean (±SD) age at baseline was 33.96±15.40 years. During six years of follow-up, the incidence of chronic kidney disease (CKD) in the population studied was 17.9%. After adjusting confounding variables, the incidence of CKD did not show any significant relationship with tea, coffee, or caffeine intakes (adjusted odds ratio and confidence intervals for CKD in the third tertile of tea and caffeine intake compared to the first tertile and in coffee drinkers compared to non-drinkers were 0.92 (0.68-1.25), 0.87 (0.63-1.21) and 1.17 (0.90-1.51), respectively).
Conclusion: Inverse and non-significant relationship between tea and caffeine consumption with the incidence of CKD and a direct and non-significant relationship between coffee consumption and the incidence of CKD were observed in this study, necessitating further prospective studies to investigate the effects of dietary intakes on CKD.

The Association between the Consumption of Dairy Products and the Risk of Cardiovascular Disease: Tehran Lipid and Glucose Study
Zahra Gaeini, Sevda Alvirdizadeh, Parvin Mirmiran, Fereidoun Azizi,
Volume 20, Issue 2 (Vol.20, No.2, Summer 2024)
Abstract
Background and Objectives: The association between the consumption of dairy products and the risk of cardiovascular disease (CVD) is not well-known yet. Here, we aimed to determine the potential effects of total intake and subtypes of dairy products on the development of CVD in an Iranian adult population.
Methods: Among adult participants of the third phase of the Tehran Lipid and Glucose Study (TLGS), after excluding those with incomplete dietary, biochemical and anthropometric data, and those who had CVD events at baseline, 2635 adults were selected and followed up till the sixth phase of the TLGS. Baseline dietary intakes were evaluated using a validated food frequency questionnaire with 168 items. There was no significant difference between the baseline characteristics of participants who did not complete the FFQ and those of the total population in the third phase of the TLGS. Finally, the risk of CVD events after adjusting for potential confounding variables was evaluated across the tertile categories of dairy products using the Cox proportional hazard regression models.
Results: During a 10.6-year follow-up, the incidence rate of CVD was 6.5%. After adjusting for confounding factors, there was no significant association between CVD risk and total dairy, low-fat and high-fat dairy, fermented and non-fermented dairy products, high- and low-fat milk, high- and low-fat yogurt, cheese, and cream cheese, as well as ice cream.
Conclusion: According to numerous evidence in previous studies that revealed there is no association between the consumption of dairy products, and CVD risk, independent of high-fat or low-fat dairy products. Hence, it is vital to reconsider dietary recommendations on lowering the intake of high-fat dairy products for the prevention of CVD.
