Background: With the increasing global burden of type 2 diabetes, prevention strategies that target prediabetes, a state of hyperglycaemia that puts individuals at high risk of type 2 diabetes, are required. We aimed to estimate global rates of transition from prediabetes to normoglycaemia or type 2 diabetes, stratified by age, sex, and race and ethnicity. We also aimed to quantify the effect of modifiable and non-modifiable risk factors on these transitions.

Introduction: The prevalence of metabolic syndrome (MetS), a cluster of metabolic abnormalities, is rising globally, particularly in the Middle East and North Africa. Gamma-glutamyl transferase (GGT) is gaining attention as a biomarker for liver function and its association with MetS and its components.
Methods: This cross-sectional study is part of the Tehran Lipid and Glucose Study (TLGS).
Background: To investigate the association of serum alkaline phosphatase (ALP) with incident metabolic syndrome (MetS) and its components, as well as the influence of sex on this relationship among Iranian adults.
Methods: The multivariable Cox proportional hazards regression models were applied to assess the associations between ALP both as continuous and categorical variables with incident MetS and its components.
Results: Among 831 subjects (467 women) with a mean age of 44.
Background: We investigated the associations between total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and triglycerides with all-cause and cardiovascular disease death among participants in the TLGS (Tehran Lipid and Glucose Study) cohort.
Methods: We included 8241 participants aged ≥30 years, who were followed until 2018. Lipid profiles were assessed as both continuous and categorical variables (quintiles) using the restricted cubic spline and Cox proportional hazards model.

Hypertension is defined as ≥130/80 mm Hg by ACC/AHA 2017, and ≥140/90 mm Hg by the ESC 2018 and NICE 2019. We examined the association between isolated diastolic hypertension (IDH, by both thresholds) and cardio-renal-metabolic (CRM) multimorbidity. From 1999 to 2018, we followed 7377 (mean age: 37.

Methods: We included 13,318 participants in the Tehran-Cardiometabolic Genetic Study (TCGS) cohort, classified into individuals without diabetes, with pre-diabetes, with type 2 diabetes, and with type 1 diabetes. Two T1D GRSs and one T2D GRS were calculated and compared between groups using the Wilcoxon test.

Background: Type 2 diabetes mellitus (T2DM) is one of the most serious public health problems all over the world. Development of local consensus on management of T2DM, providing clinicians, researchers, and policymakers with updated and valid evidence in consideration of practical issues, is crucial. Therefore, we aimed to develop a consensus report on management of T2DM in Iran.

Background: Studies have reported that the activity of alanine aminotransferase (ALT) is a key biomarker for screening liver cell damage, such as non-alcoholic fatty liver disease (NAFLD).
Objectives: Since individuals with metabolic syndrome (MetS) are at high risk for NAFLD, we aimed to determine gender-specific ALT thresholds for screening MetS in the Tehranian population.
Methods: We conducted a cross-sectional study from 2018 to 2022, involving 4,968 adults aged 20 - 70 years (2,732 females).
Background And Aims: To examine the impact of early-life lipid profile trajectories in adolescence on subclinical atherosclerosis, evidenced by carotid intima-media thickness (cIMT) in adulthood.
Methods And Results: In this trajectory analysis of 1,006 TLGS participants (472 male, mean age = 14.72 ± 3.
Aim: To investigate, for the first time, the association between undiagnosed diabetes-using a single-sample confirmatory definition-and prevalent hypertension and cardiovascular diseases (CVD) in an Iranian national population. A few studies on this topic have been limited to Western populations.
Methods: The study included 16328 adults aged ≥ 30 years.
Introduction: While type 2 diabetes (T2DM) has become a major health issue in the North American and Caribbean region, the effects of weight change on incident T2DM, conditional on either initial or attained weight, are poorly addressed. Therefore, we aimed to assess the impact of 3-year weight change on incident T2DM over 6 years among US individuals.
Methods: A total of 8377 participants aged 45-64 years (4601 women), free of T2DM or cancer at baseline from the Atherosclerosis Risk in Communities (ARIC) study were included.
Objectives: To evaluate the relationship between short-term exposure to ambient air pollutants and cardiovascular disease (CVD) hospitalizations.
Methods: A time-series analysis was conducted using data from the Tehran Lipid and Glucose Study cohort of 3454 residents (1880 women) aged 50-70 from District 13 of Tehran. Follow-up data from January 1999 to March 2018 were analyzed.
Objectives: The effect of the duration of medication with metformin and sulfonylurea (SUs) on microvascular complications based on the duration of type 2 diabetes (DM2) is unclear. The aim of this study was to investigate the association of medication time with metformin and SUs and microvascular complications in newly diagnosed DM2 patients.
Methods: In this prospective multi-cohort study, data from 3,904 newly diagnosed DM from three cohorts of the Tehran Lipid and Glucose Study (TLGS), the Multi-Ethnic Study of Atherosclerosis (MESA), and the Atherosclerosis Risk in Communities (ARIC) with a mean age of 59.
The effect of duration of medication with metformin and sulfonylurea (SUs) on cardiovascular diseases (CVD) and mortality events by duration of type 2 diabetes (DM) is unclear. This study aimed to investigate the effect of duration of treatment with metformin and SUs on CVD and mortality events based on DM duration in newly diagnosed DM patients. Data from three prospective cohorts of Tehran Lipid and Glucose Study (TLGS), Multi-Ethnic Study of Atherosclerosis (MESA), and Atherosclerosis Risk in Communities (ARIC) including 4108 newly diagnosed type 2 diabetes individuals (mean age, 59.

Rationale & Objective: The impact of the estimated glomerular filtration rate (eGFR) slope on the progression of heart failure (HF) remains unclear. This study investigated the association of eGFR slope and the occurrence of incident HF in older adults either at elevated risk for HF or with cardiac abnormalities (structural, hemodynamic, or biomarker) (pre-HF).

Purpose: The incidence of prediabetes has been on the rise, indicating a growing public health concern, as individuals with prediabetes are at higher risk of developing type 2 diabetes. This study aimed to determine the effects of simple interventions on the regression of pre-diabetes status into normoglycemia and also prevent progression to diabetes in a pragmatic community trial.
Methods: A total of 2073 (761 intervention; 1,312 controls) participants with pre-diabetes were included in the present secondary data analysis; cases with diabetes or normoglycemia were identified during nine years of follow-up.
Background: Dietary patterns and lifestyle factors can influence the intensity of systemic inflammation and, consequently, the development and progression of coronary artery calcification (CAC). This study aimed to explore the relationship between the inflammatory potentials of diet and lifestyle, as captured by novel dietary and lifestyle inflammation scores (DIS and LIS), with CAC incidence and progression.
Methods: We analyzed data on 5949 Black and White men and women ≥ 45 years old participating in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.
Purpose: The use of statins for the primary prevention of cardiovascular diseases (CVD) is associated with various beneficial outcomes, alongside certain undesirable effects. This study aims to determine optimal risk thresholds above which statin therapy yields a net benefit, considering both the positive effects and potential adverse effects, as well as their probabilities and patient preferences.
Methods: Quantitative benefit-harm balance modeling was applied to the Iranian general population aged 40 to 75 years with no history of CVD.
