Prevalence and Trends of Vitamin D Deficiency among Iranian Adults: A Longitudinal Study from 2001-2013.

Vitamin D deficiency/insufficiency is currently considered to be a re-emerging public health problem globally. This study was designed to determine the prevalence of vitamin D deficiency and insufficiency and to investigate its trend from 2001 to 2013 in a longitudinal study of Iranian adults. This study was part of a population-based, longitudinal ongoing study of Iranian healthy adults aged 35 y and older at baseline.

Secular Trend of Metabolic Syndrome and Its Components in a Cohort of Iranian Adults from 2001 to 2013.

Background: Metabolic syndrome (MetS) and its components increase the risk of developing cardiovascular diseases, type 2 diabetes, and all-cause mortality. Reports on the trends of MetS and its components in longitudinal studies are scarce, especially in low- and middle-income countries. This study was designed to investigate the prevalence and trends of MetS and its components in a cohort of Iranian adults from 2001 to 2013.

Magnesium status and the metabolic syndrome: A systematic review and meta-analysis.

Objectives: To systematically review the published evidence regarding the association between Mg intake and serum concentrations with MetS and, if possible, to summarize the results using a meta-analysis.

Methods: PubMed, ISI Web of Science, Scopus, and Google Scholar were searched to identify related articles. Fully adjusted odds ratios (ORs) of MetS in participants with the highest intake of Mg compared with those who had the least consumption, and the mean difference in serum Mg levels between patients with MetS and their controls were extracted for the meta-analysis.

Does the impact of metabolic syndrome on cardiovascular events vary by using different definitions?

Background: Metabolic Syndrome (MetS) is a complex disorder which increases the risk of chronic diseases, including cardiovascular diseases and diabetes mellitus. As a result of modern lifestyles, the prevalence of MetS has been rising globally. This study aims to investigate whether overall prevalence of MetS varies when using different definitions of MetS and to identify the best and most predictive definition of the MetS for cardiovascular disease (CVD) events over 10 years in a cohort of an Iranian population.
