Latar belakang. Obesitas pada anak berhubungan dengan meningkatnya risiko sindrom metabolik, seperti resistensi insulin. HOMA-IR merupakan marker yang sering digunakan untuk menilai resistensi insulin. Chemerin merupakan protein 18 kDa yang dihasilkan jaringan adiposa, berfungsi sebagai chemoatractant memegang peran penting berkontribusi terhadap perkembangan inflamasi dan resistensi insulin. Tujuan. Untuk mengetahui hubungan kadar chemerin dengan HOMA-IR pada remaja obesitas.Metode. Penelitian ini merupakan penelitian cross sectional yang dilakukan pada 3 sekolah menengah umum (SMU) di kota Padang. Jumlah sampel berjumlah 28 remaja obesitas dan 28 remaja dengan IMT normal. Obesitas ditentukan berdasarkan nilai IMT, HOMA-IR dihitung berdasarkan rumus yang menggunakan nilai glukosa dan insulin puasa. Glukosa diukur dengan metode glucose hexokinase fotometrik, insulin diperiksa dengan metode chemiluminessence immunoassay dan kadar plasma chemerin dengan metode ELISA. Data dianalisis dengan sistem komputerisasi dengan uji korelasi.Hasil. Kadar plasma chemerin lebih tinggi pada kelompok obesitas dibandingkan kontrol 121,52 (SD 2,09) ng/ml vs 97,23(SD 2,41) ng/ml, p: 0,001 dan pada kelompok obesitas dengan resistensi insulin dibandingkan non resistensi insulin 133,1(SD 19,24) vs 115,09 (SD 19,52), p=0,001. Terdapat hubungan lemah kadar chemerin dengan nilai HOMA-IR pada obesitas(r=0,382;p=0,045) dan hubungan lemah kadar chemerin dengan nilai HOMA-IR pada obesitas resistensi insulin (r=0,297;p=0,405).Kesimpulan. Terdapat hubungan lemah kadar chemerin dengan nilai HOMA-IR pada remaja obesitas, dan hubungan lemah kadar chemerin dengan nilai HOMA-IR pada obesitas resistensi insulin.

ObjectiveSeveral cutoff points of the homeostasis model assessment of insulin resistance (HOMA-IR; varying from 2.5 to 4.0) have been suggested for diagnosing IR in youth. In this study, we determined the distribution of the HOMA-IR in Mexican children and adolescents.Design and methodsA total of 6132 children and adolescents from San Luis Potosi, León, Queretaro, and Durango, which are cities in central and northern Mexico, were enrolled in a population-based cross-sectional study. Eligible participants were apparently healthy children and adolescents aged 6–18 years. Pregnancy and the presence of chronic illnesses were exclusion criteria.ResultsA total of 3701 (60.3%) girls and 2431 (39.7%) boys were included in this study. In the overall population, the mean body mass index, insulin levels, and fasting glucose levels were 21.8±1.3 kg/m2, 7.1±3.2 μU/ml, and 86.2±10.0 mg/dl respectively. The concentrations of insulin and fasting glucose gradually increased from 6 to 12 years of age, whereas the concentrations tended to plateau in the 13- to 18-year-old population. The absolute mean of the HOMA-IR was 2.89±0.7. The HOMA-IR gradually increased with age and reached a plateau at 13 years of age.ConclusionsBecause the insulin concentrations, glucose levels, and HOMA-IR exhibited a gradual increase with age that was not related to obesity, our results suggested that the evaluation of IR in children should be based on percentiles of the HOMA-IR rather than a dichotomous value derived from a single cutoff point.

OBJECTIVE: Whether the adipocyte-derived protein adiponectin is associated with insulin resistance independently of the effects of adiposity and the diabetic state is an important question. We explored, in a cross-sectional study of 486 Japanese nondiabetic women, the relationship between the calculated insulin resistance (homeostasis model assessment ratio (HOMA-R)) and adiponectin levels determined using a validated sandwich ELISA. DESIGN AND METHODS: All participants were stratified into tertiles for HOMA-R (approximately <1.5, 1.5< or = approximately <3.0, 3.0< or = approximately ) and the differences across tertiles of continuous variables were tested with ANOVA. Two-way ANOVA was used to determine possible relationships for plasma adiponectin between tertiles of HOMA-R and several stratified parameters. Multiple regression analyses were performed with HOMA-R or fasting serum insulin as dependent variable, and diastolic blood pressure (BP), body mass index (BMI), serum triglyceride (TG), leptin and adiponectin as independent determinants. RESULTS: Mean plasma adiponectin in the high HOMA-R group decreased compared with that in the low HOMA-R group both before (mean+/-s.e.m. 6.2+/-0.6 vs 9.2+/-0.3 microg/ml, P<0.001) and after adjustment for body fat mass (BFM) as kg or percent (0.31+/-0.04 vs 0.69+/-0.03, 0.18+/-0.02 vs 0.34+/-0.01, both P<0.001). HOMA-R was inversely associated with adiponectin levels both before (r=-0.37, P<0.001) and after adjustment for BFM (r=-0.49, -0.46, both P<0.001). After covariate adjustment for age, diastolic BP, BMI and serum TG, HOMA-R retained a significant correlation with adiponectin/BFM (kg). Both adiponectin and leptin were the significant determinants of HOMA-R or fasting insulin in multiple regression models. CONCLUSIONS: Adiponectin was inversely associated with insulin resistance in nondiabetic subjects, independently from age, BP, adiposity and serum lipids. Because adiponectin is thought to have an anti-atherogenic action, the presence of hypoadiponectinemia may predispose subjects to atherosclerosis, and may progress the atherogenesis in insulin resistance.

Background and objectives: Evidence shows that shift work may be correlated with insulin resistance (IR). Therefore its estimation in clinical and prevention practice is of great significance. A cross-sectional study was performed to examine the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) Index among healthcare shift workers (HCSW). Materials and Methods: A total of 272 healthcare workers (HCWs) were invited to participate in the study within an occupational surveillance framework, 137 were HCSW while 135 were healthcare non-shift workers (HCNSW). Fasting glucose, insulin, and HOMA-IR Index were evaluated in each participant and correlated with shift workers. Results: Indicators of glucose metabolism were significantly higher in HCSW p < 0.001, and logistic regression analysis confirmed a significant positive association between increased values of HOMA-IR Index and shift workers (p < 0.05). Conclusions: Shift work could be a risk factor in developing insulin resistance and metabolic syndrome.

Background and Objectives: The key pathogenetic mechanism of glucose metabolism disorders, insulin resistance (IR), can be assessed using the Homeostasis Model Assessment of IR (HOMA-IR). However, its application in clinical practice is limited due to the absence of cut-offs. In this study, we aimed to define the cut-offs for the Czech population. Methods: After undergoing anthropometric and biochemical studies, the sample of 3539 individuals was divided into either nondiabetics, including both subjects with normal glucose tolerance (NGT, n = 1947) and prediabetics (n = 1459), or diabetics (n = 133). The optimal HOMA-IR cut-offs between subgroups were determined to maximize the sum of the sensitivity and specificity for diagnosing type 2 diabetes mellitus (T2DM) or prediabetes. The predictive accuracy was illustrated using receiver operating characteristic (ROC) curves. Logistic regression was performed to assess the association between a target variable (presence/absence of T2DM) depending on the HOMA-IR score as well as on the age and sex. Results: The HOMA-IR cut-off between nondiabetics and diabetics for both sexes together was 3.63, with a sensitivity of 0.56 and a specificity of 0.86. The area under the ROC curve was 0.73 for T2DM diagnosing in both sexes. The HOMA-IR cut-off between the NGT subjects and prediabetics was 1.82, with a sensitivity of 0.60 and a specificity of 0.66. Logistic regression showed that increased HOMA-IR is a risk factor for the presence of T2DM (odds ratio (OR) 1.2, 95% confidence interval (CI) 1.14–1.28, p < 0.0001). The predictive ability of HOMA-IR in diagnosing T2DM is statistically significantly lower in females (OR 0.66, 95% CI 0.44–0.98). The results are valid for middle-aged European adults. Conclusions: The results suggest the existence of HOMA-IR cut-offs signaling established IR. Introduction of the instrument into common clinical practice, together with the known cut-offs, may contribute to preventing T2DM.

Abstract Context: Low-grade inflammation is associated with insulin resistance and precedes the onset of type 2 diabetes mellitus in adults, but there are no comparable data in youth. Objective: The objective of the study was to characterize the pattern of subclinical immune activation that is associated with indices of obesity and insulin resistance in youth and analyze whether this association is explained by obesity. Design: This was a cross-sectional study. Setting: Medical check-up of schoolchildren was conducted by the Public Health Office in Düsseldorf (Germany). Participants: Participants included 519 adolescents (mean age 15.5 ± 0.8 yr). Main Outcome Measures: Measures included body mass index (BMI) and waist circumference (WC) as indices of obesity; fasting glucose, insulin, and homeostasis model assessment of insulin resistance; serum concentrations of TNFα, IL-6, IL-8, IL-18, monocyte chemoattractant protein-1, interferon-γ-inducible protein (IP)-10 and adiponectin as immunological variables. Results: In age-, sex-, and lipid-adjusted analyses, IL-6, IL-18, IP-10, and adiponectin (inversely) were associated with both BMI and WC (all P ≤ 0.002). None of the immune markers was related to glucose, but IL-6, IL-18, and adiponectin (inversely) were associated with insulin and homeostasis model assessment of insulin resistance in age- and sex-adjusted models. Adjustment for BMI or WC indicated that a considerable proportion of these associations may be mediated by obesity. Conclusions: We found that a differential low-grade immune activation is associated with parameters of obesity in adolescents. Moreover, there is evidence that IL-6, IL-18, IP-10, and adiponectin (inversely) are associated with insulin resistance and that these associations can mainly be attributed to obesity.

ObjectiveTo study the association of vaspin with glucose metabolism.DesignCross-sectional and intervention study.Subjects and methodsThe association of serum vaspin with metabolic and anthropometric characteristics was investigated in 108 volunteers. Euglycemic–hyperinsulinemic clamps (EHC) were performed in 83 of the participants. Changes of circulating vaspin levels were additionally studied in a crossover study using 300 min EHC with lipid versus saline infusion (n=10).ResultsNeither glucose tolerance status nor insulin sensitivity, both as measured using EHCs and using homeostasis model assessment for insulin resistance (HOMA-IR), was significantly associated with serum vaspin in the cross-sectional study. Furthermore, there was no effect of short-term lipid-induced insulin resistance due to a 300 min intravenous lipid challenge on circulating vaspin. However, circulating vaspin levels were significantly elevated in women using oral contraceptives (OC), both compared to women without OC intake (1.17±0.26 vs 0.52±0.09 ng/ml, P=0.02) and males (1.17±0.26 vs 0.29±0.04 ng/ml, P=0.01). After exclusion of OC using females and stratification according to body mass index (BMI), a significant sexual dimorphism in subjects with a BMI <25 kg/m2 was observed (males 0.21±0.04 ng/ml versus females 0.70±0.16 ng/ml, P=0.009).ConclusionOur results support the existence of a sexual dimorphism regarding circulating vaspin. The lack of an association of serum vaspin with HOMA-IR and M value indicates, however, no major role for vaspin concerning insulin sensitivity in nondiabetic humans.

ΣΚΟΠΟΣ: Ο στόχος της παρούσας μελέτης ήταν να ερευνηθεί ο ρόλος της ρεζιστίνης στους ηλικιωμένους μη διαβητικούς σε διαφορετικά στάδια της χρόνιας πάθησης νεφρών (CKD) συμπεριλαμβανομένης της αιμοδιάλυσης. ΥΛΙΚΟ ΚΑΙ ΜΕΘΟΔΟΙ: Εξετάσαμε τα επίπεδα της ρεζιστίνης ορού σε σχέση με τα δημογραφικά και κλινικά στοιχεία, τις μεταβολικές παραμέτρους και τους δείκτες φλεγμονής σε μια διατομική (cross-sectional) μελέτη 80 ηλικιωμένων ασθενών διαχωρισμένων σε τέσσερις ομάδες 20 ασθενών κάθε μια, σύμφωνα με το eGFR (glomerular ποσοστό διήθησης) και ταιριασμένους για την ηλικία (± 5 χρόνια) και το φύλο. Ασθενείς με eGFR περισσότερο από 90 mL/min χρησίμευσαν ως ομάδα ελέγχου. Πραγματοποιήθηκαν αιματολογικές, βιοχημικές και ανοσοχημικές αναλύσεις από εμπορικά διαθέσιμες ανοσολογικές δοκιμασίες ενζύμων (ELISA). ΑΠΟΤΕΛΕΣΜΑΤΑ: Τα αποτελέσματά μας έδειξαν: 1) τα επίπεδα της ρεζιστίνης ορού ήταν δύο φορές πιο υψηλά στους ασθενείς με προηγμένη CKD ειδικά σε εκείνους που υποβάλλονται στην αιμοδιάλυση έναντι των ασθενών ελέγχου, 2) τα επίπεδα της ρεζιστίνης ορού αφορούσαν άμεσα τους δείκτες φλεγμονής (TumorNecrosis Factor-α και την C-Reactive Protein) και τα επίπεδα φωσφορικού άλατοςορού, και 3) τα επίπεδα της ρεζιστίνης ορού αφορούσαν αντιστρόφως τη λευκωματίνη, το eGFR, και τα επίπεδα του αιματοκρίτη. Αποτύχαμε να αποκαλύψουμε οποιαδήποτε σχέση μεταξύ των επιπέδων της ρεζιστίνης και του ομοιοστατικού πρότυπου αποτελέσματος αξιολόγησης της αντίστασης ινσουλίνης(Homeostasis Model Assessment Score of Insulin Resistance (HOMA-IR)), τον δείκτη μάζας σώματος, την χοληστερίνη και τα επίπεδα της λεπτίνης. ΣΥΜΠΕΡΑΣΜΑ: Τελικά, τα αποτελέσματα αυτής της μελέτης προτείνουν ότι υπάρχει μια συσχέτιση της ρεζιστίνης και των δεικτών κατάστασης υποσιτισμού-φλεγμονής σε ηλικιωμένους μη διαβητικούς ασθενείς με χρόνια πάθηση νεφρών.

ABSTRACT Objective To identify cut-off points of neck circumference measurement to predict insulin resistance in adolescents. Methods Cross-sectional analysis with data derived from the Study of Cardiovascular Risks in Adolescents, nationwide, multicenter, school-based survey. We evaluated 901 adolescents, aged 12 to 17, from public and private schools in two cities of Sergipe state in Brazil. We measured demographic, anthropometric, and biochemical data, and insulin resistance using Homeostasis Model Assessment-Insulin Resistance. We used multiple linear regression and logistic analysis to evaluate the association between dependent variables (biochemical) and independent variables (anthropometric) controlled by body mass index, age, gender, and Tanner’s stage. We used the Receiver operating characteristic curve to determine cut-off points of neck circumference that can identify insulin resistance. Results The multiple linear regression analysis showed a positive association between neck circumference measurement with fasting glycemia and glycated hemoglobin (p<0.001) and a negative association with insulin (p<0.024). Furthermore, in logistic regression, the measurement of neck circumference was the only anthropometric indicator positively correlated with homeostasis model assessment-insulin resistance. The cut-off points of neck circumference for predicting insulin resistance were: 30.55cm for female pubertal and 32.10cm for post-pubertal adolescents; 35.90cm for male pubertal adolescents and 36.65cm for post-pubertal adolescents. Conclusions The measurement of neck circumference is a simple, practical anthropometric indicator and can be used as a screening tool to identify insulin resistance in adolescents.

Abstract Objectives To explore genetic variants for quantitative traits of type 2 diabetes (T2D) such as insulin resistance and insulin release among Chinese adults. Methods A total of 2216 subjects were selected from cross-sectional 2010–2012 China National Nutrition and Health Surveillance. Fasting plasma glucose(FPG) and fasting serum insulin(FSIN) were tested and 81 T2D single nucleotide polymorphisms (SNPs) were genotyped. Insulin resistance was defined by exceeding top quartile of insulin resistance of homeostasis model assessment(HOMA-IR) index value and insulin release was defined under lower quartile of insulin release of homeostasis model assessment(HOMA-B) index value in nondiabetic individuals, respectively. Logisticregression model was utilized to explore association between each SNP and quantitative traits. Results The risk C allele of GRK5 rs10886471, the risk C allele of IGF2BP2 rs1470579 and the risk A allele of GCK rs4607517 was associated with increased HOMA-IR(P = 0.043, P = 0.014, P = 0.050), and the risk T allele of SEC16B rs574367 was associated with decreased HOMA-IR(P = 0.028). The risk A allele of SCAP rs4858889 associated with decreased HOMA-B(P = 0.004), while FTO rs1558902 and MAEA rs6815464 both had inverse effect on HOMA-B(P = 0.018, P = 0.048). Conclusions The rs10886471, rs1470579 and rs4607517 might be risk loci for T2D by mediating insulin receptors or insulin signal transduction to reduce insulin sensitivity. Individuals carrying the risk A allele of rs4858889 predisposed to T2D may by decreasing insulin secretion. Our findings will provide clue for casual relationship between SNPs and T2D-related traits.
