[ 2 ] - Hypovitaminosis D in Adults Living in a Sunny City: Relation to Some Cardiometabolic Risk Factors, National Food and Nutrition Surveillance

Background and Objectives: Reports indicate that hypovitaminosis D is extremely common worldwide and is re-emerging as a major health problem globally. In the present study, the main objectives were: 1) to examine whether healthy men and women living in Ahvaz have adequate vitamin D status; 2) to assess association between vitamin D status and some cardiometabolic risk factors. Materials and M...

[ 3 ] - Evaluation of Iron Bioavailability in Caco-2 cell Culture Model: Modification of the Original Method

Background and Objectives: In the original in vitro method for evaluation of iron bioavailability using caco-2 cell model, ferritin formation by cells is considered as a functional indicator of both absorption and utilization of iron. However, as iron is measured in the tested material and then ferritin concentration is measured in caco-2 cell lysate, it is almost impossible to have a concrete ...

[ 4 ] - Prevalence of Obesity and Overweight and Its Associated Factors in Urban Adults from West Azerbaijan, Iran: The National Food and Nutritional Surveillance Program (NFNSP)

Background and Objectives: Globally, the prevalence of overweight/obesity is increasing at an alarming rate. According to the World Health Organization (WHO), about 1.9 billion adults worldwide are overweight, and of these, over 600 million are obese. The purpose of this study was to determine the prevalence of overweight and obesity in West Azerbaijan, Iran, in 2014. Materials and Methods: ...

[ 5 ] - Vitamin D Deficiency is Associated with the Metabolic Syndrome in Subjects with Type 2 Diabetes

Background and Objectives: There is convincing evidence that subjects concomitantly affected by type 2 diabetes (T2D) and metabolic syndrome (MeS) are at greater risk for cardiovascular disease (CVD). Many metabolic derangements in T2D might be attributed to poor vitamin D status. The purpose of this study was to investigate the associations among vitamin D status, MeS and glycemic status in su...

[ 6 ] - Efficacy of Food Fortification with Vitamin D in Iranian Adults: A Systematic Review and Meta-Analysis

There are a number of reports showing high prevalence of hypovitaminosis D across Iran. The objective of this study was to evaluate whether food fortification with vitamin D has the potential to increase serum 25(OH)D concentrations in Iranian people. MEDLINE, PubMed, EMBASE, and The Cochrane Central Register of Controlled Trials were searched for randomized controlled clinical trials involving...

[ 7 ] - Influence of Time and Temperature on Stability of Added Vitamin D3 During Cooking Procedure of Fortified Vegetable Oils

Background and Objectives: Previous research has established that Vitamin D3 (Cholecalciferol) deficiency is considered to be a highly prevalent nutritional problem worldwide. Data from National Food and Nutrition Surveillance Program (2015) revealed that prevalence of vitamin D3 deficiency in Iran is more than 70% of the population. Vegetable oils are considered to be potential candidates for ...

[ 8 ] - Development of New Predictive Equations to Estimate Basal Metabolic Rrates in Iranian Adults: A Study Protocol

Background and Objectives: Studies indicate over-estimation of basal metabolic rate (BMR) using common equations for the Asian people. The present study aims to develop new predictive equations for the Iranian people and to compare these equations with commonly used formulas. Materials and Methods: Total, 150healthy subjects aged 18-60 yrare invited to the Laboratory of Nutrition Research, Nat...

[ 9 ] - Effects of Vitamin D Supplementation on Depression Status, Selected Pro-inflammatory Biomarkers and Neurotransmitters in Depressive Patients: A Study Protocol

Background and Objectives: Up to date, several pathophysiological mechanisms are suggested for evolution of depression, including inflammation, neurotransmitter and vitamin D pathways. The aim of this study is to evaluate the effects of vitamin D supplementation on serum 25-hydroxycalciferol [25(OH) D], intact parathyroid hormone (iPTH), some pro-inflammatory biomarkers and neurotransmitters su...

[ 10 ] - Are there Relationships between the VDR-FokI Polymorphism and Vitamin D and the Insulin Resistance in Non-melanoma Skin Cancer (NMSC) Patients? A Protocol for Case-control Studies

Background and Objectives: Evidence indicate relationships between the sunlight exposure, vitamin D status and non-melanoma skin cancer (NMSC) risk. Vitamin D receptor (VDR) polymorphisms have been linked to metabolic changes in insulin resistance and various cancers. The purpose of this study is to investigate relationships between the sunlight exposure and the NMSC risk. Furthermore, relation...
