An increasing number of studies report associations between low serum 25-hydroxyvitamin D [25(OH)D] level and insulin resistance; however, whether low vitamin D levels directly contribute to increased insulin resistance is unclear. We investigated the impact of residential area on the association between 25(OH)D and insulin resistance in elderly Koreans. Using data from the Korean Urban Rural E...

BACKGROUND To investigate the prevalence of metabolic syndrome (MetS) in young Chinese population and assess the association between HOMA-IR and different components of MetS in young Chinese men. METHODS Overall 5576 young Chinese subjects (age range [19-44 yr], 3636 men) were enrolled in, who visited our Health Care Center for a related health checkup from March to December 2008. The interna...

Objectives. To study the cut-off point of Homeostatic Measurement Assessment-Insulin Resistance (HOMA-IR) as a screening test for detection of glucose intolerance in Thai women with polycystic ovary syndrome (PCOS). Study Design. Cross-sectional study. Setting. Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital. Subject. Two hundred and fifty Thai PCOS women who atten...

Objectives. The aim of this study was to investigate the relationship between serum vitamin D and insulin resistance in Chinese subjects without diabetes mellitus. Methods. Serum 25(OH)D was measured in 897 individuals with normal glucose tolerance (NGT). Oral glucose tolerance tests (OGTTs) were conducted to exclude cases with diabetes, impaired fasting glucose (IFG), and impaired glucose tole...

This study aims to expand the evaluation of normal weight obesity (NWO) and its association with insulin resistance using an NHANES (1999-2006) sample of US adults. A cross-sectional study including 5983 men and women (50.8%) was conducted. Body fat percentage (BF%) was assessed using dual-energy X-ray absorptiometry. Expanded normal weight obesity (eNWO) categories, pairings of BMI and body fa...

BACKGROUND Women with a history of both parental type 2 diabetes (pt2DM) and previous gestational diabetes (pGDM) represent a group at high risk of cardiovascular events. We hypothesized that pGDM changes cardiometabolic risk markers levels as well as theirs associations with glucose indices in nondiabetic pt2DM women. METHODS Anthropometric parameters, glucose regulation (OGTT), insulin resi...

OBJECTIVE To determine whether inherited changes in insulin secretion or sensitivity could predispose to type 1 diabetes, we studied identical twins of type 1 diabetic patients. RESEARCH DESIGN AND METHODS We studied prospectively a consecutive series of 27 identical twins of patients with type 1 diabetes who were initially nondiabetic, as well as 14 control subjects, over a period of 18 year...

BACKGROUND The purpose of this study was to investigate the association between obesity, fitness levels and cardiovascular (CVD) risk factors, and to identify the correlation between of insulin-like growth factor (IGF)-1, IGF binding protein-3 (IGFBP-3), and carotid intima media thickness (IMT) in Korean adolescents. METHODS A total of 225 high school males with a mean age of 16.96±0.23 years...

INTRODUCTION Gestational diabetes mellitus (GDM) is a heterogeneous disease. We hypothesized that fasting hyperglycaemia, defined as impaired fasting glycaemia (IFG), is a marker of metabolic heterogeneity of GDM. The aim of this study was to compare selected metabolic parameters in two groups of women with GDM, one with normal fasting glycaemia (NFG GDM) and another with IFG, to test this hypo...

Objective: To observe the changes in insulin resistance patients with gestational diabetes mellitus (GDM) based on detection of serum microRNA-372-3p and glucose transporter protein 4 (GLUT4) levels. Methods: We conducted a retrospective cohort study 42 who were diagnosed GDM hospitalized our hospital during period from January 2017 to December 2021 another had normal pregnancy same by collecti...
