results serum estradiol levels tended to have a negative correlation with homeostasis model assessment of insulin resistance (homa-ir) in premenopausal women but not in postmenopausal women. on the other hand, free testosterone levels tended to have a positive correlation with homa-ir in postmenopausal women but not in premenopausal women. serum shbg levels showed significant negative correlati...

This study examined changes in insulin resistance (IR) in 120 youth over two years. IR was quantified via homeostatic model (HOMA-IR), and weight status changes were quantified via body mass index (BMI). When all participants were considered, the mean HOMA-IR and BMI increased 13.4% and 1.65 units, respectively. Change in BMI z-score and percent change in HOMA-IR were moderately associated (r =...

BACKGROUND Homeostasis model assessment of insulin resistance (HOMA-IR) is a surrogate estimate of directly measured insulin resistance that been robustly proven to be associated with diabetes and cardiovascular disease. The purpose of this study was to evaluate the use of several simple indicators to identify postmenopausal women with insulin resistance estimated by HOMA-IR. METHODS We recru...

BACKGROUND Visceral obesity is positively related to insulin resistance. The nature of the relationship between waist circumference and insulin resistance has not been known in Japanese populations. This study examined the relationship between waist circumference and insulin resistance and evaluated the optimal cutoff point for waist circumference in relation to insulin resistance in middle-age...

Growing evidence supports that air pollution exposure has become a risk factor of type II diabetes mellitus through the induction insulin resistance (IR), but presented findings did not provide consistent relationship between and IR in temporal scale magnitude. Reported associated with exposure, branched-chain amino acids (BCAAs) blood might modify association IR. We took advantage an existing ...

BACKGROUND Polycystic ovary syndrome (PCOS) is associated with insulin resistance (IR) and compensatory hyperinsulinemia. IR is recognized as a major risk factor for the development of type 2 diabetes mellitus. However, few studies have investigated IR in women with PCOS and normal glucose tolerance. The objective of this study was to evaluate IR and β-cell function in women with PCOS and norma...

Metabolic syndrome (MetS) has an important epidemiological relevance due to its increasing prevalence and association with type 2 diabetes and cardiovascular disease. Insulin resistance is a core feature of the MetS. HOMA-IR is a robust clinical and epidemiological marker of MetS. Adiponectin is an adipokine with insulin-sensitizing and anti-inflammatory functions; its levels decrease as number...

BACKGROUND We investigated the relationships of adiponectin/leptin (A/L) ratio with cardiovascular risk factors, insulin resistance index, and metabolic syndrome (MS) in apparently healthy Korean male adults. METHODS Sixty-eight male subjects were enrolled among the participants of an annual health check-up program (mean age, 55.1 years). Percent body fat (%) was measured using a bioelectric ...

BACKGROUND Insulin resistance (IR) is prevalent in uraemia. Recent experimental studies suggested IR to be a central mechanism for uraemic malnutrition. However, it is not known whether IR is related to muscle wasting in non-diabetic end-stage renal disease (ESRD) patients. METHODS We cross-sectionally assessed IR and muscle wasting in 21 non-diabetic ESRD patients who admitted for the initia...
