We investigated the cutoff values of surrogate of insulin resistance for diagnosing metabolic syndrome in Korean adults. The data from 976 non-diabetic individuals (484 men and 492 women) aged 30-79 yr were analyzed. We determined the odds ratios for the prevalence of metabolic syndrome according to the quartiles of fasting insulin, homeostasis model for insulin resistance (HOMA-IR), and quanti...

AIM To determine whether fasting serum uric acid is associated with the insulin sensitivity index or with other anthropometric, metabolic or environmental features of the insulin resistance syndrome in a population-based sample of young healthy Caucasians. METHODS The protocol included 380 unrelated Caucasian subjects (age 18-32 years) who had their insulin sensitivity index and glucose effec...

BACKGROUND The association between hyperinsulinemia and obesity is well known. However, it is uncertain especially in childhood obesity, if initial fasting hyperinsulinemia predicts obesity, or obesity leads to hyperinsulinemia through insulin resistance. OBJECTIVE To investigate the predictive effect of fasting plasma insulin on subsequent weight change after a 5-year interval in childhood. ...

background: saffron is the dried stigmata of the flowers of saffron (crocus sativus l., iridaceae). saffron and its major active constituents, crocin (crocetin glycoside), crocetin and safranal, have a variety of pharmacological effects including high antioxidant properties and crocetin has insulin sensitizing effect possibly due to its antioxidant activity. oral crocin is not absorbed and is h...

OBJECTIVE Obesity is associated with hyperinsulinemia and increased level of C-reactive protein in older children and adults, but little is known about these relationships in very young children. We examined these relationships in healthy 2- to 3-year-old children. RESEARCH METHODS AND PROCEDURES Analyses were performed on data from 491 healthy 2- to 3-year-old Hispanic children enrolled in a...

OBJECTIVE In this study we compared fasting insulin and measures of insulin sensitivity (M) based on fasting insulin and glucose (i.e., homeostasis model assessment [HOMA], quantitative insulin sensitivity check index [QUICKI], and fasting glucose-to-insulin ratio [FGIR]) or triglycerides to the insulin clamp in a cohort of children/adolescents. RESEARCH DESIGN AND METHODS The subjects were M...

Insulin may serve as a key causal agent which regulates fat accumulation in the body. Here we assessed the causal relationship between fasting insulin and adiposity using publicly-available results from two large-scale genome-wide association studies for body mass index and fasting insulin levels in a two-sample, bidirectional Mendelian Randomized approach. This approach is only valid on the co...

background: obesity and overweight are accompanied with insulin resistance markers and diagnosed as a metabolic risk factor in prevalence and develop the asthma severity. regardless of biological role of inflammation markers in asthma, the effective mechanisms in relation to obesity and asthma are not fully understood. methods: this study investigates the relationship between insulin resistance...

Background: Ramadan fasting for pregnant women with diabetes remains controversial and underreported. The objective of this study was to determine the glycemic control in pregnant diabetic women on insulin who fasted during Ramadan. Methods: This was a retrospective study carried out over a period of three years including pregnant diabetic women, who were on short-acting, intermediate-a...

OBJECTIVE This study evaluated insulin secretion and insulin sensitivity in healthy subjects with normal fasting glucose. RESEARCH DESIGN AND METHODS A total of 148 healthy women (aged 53-70 years) underwent a glucose-dependent arginine stimulation test and a 2-h euglycemic-hyperinsulinemic clamp. In the arginine test, arginine (5 g) was injected intravenously under baseline (fasting) conditi...
