Objective: To examine the (1) normal ranges of anthropometric and insulin resistance/sensitivity indices (homeostatic model assessment for insulin resistance, homeostatic model assessment for insulin sensitivity, and quantitative insulin sensitivity check index) for Iranian pregnant women and their newborns and (2) associations between maternal anthropometric and metabolic values and infants’ birth weights among Iranian women. Methods: Anthropometric and metabolic values of 163 singleton non-diabetic pregnant women in Tehran, Iran (2014) were collected before and during pregnancy and at delivery. Linear regression, multivariable regression, and Student t tests were used to evaluate correlations between birth weight and maternal variables. Results: Linear regression modeling suggested that maternal serum glucose ( p = 0.2777) and age ( p = 0.6752) were not associated with birth weight. Meanwhile, maternal weight and body mass index before pregnancy ( p = 0.0006 and 0.0204, respectively), weight at delivery ( p = 0.0036), maternal height ( p = 0.0118), and gestational age ( p  = 0.0016) were positively associated with birth weight, while serum insulin ( p = 0.0300) and homeostatic model assessment for insulin resistance ( p = 0.0334) were negatively associated with infant’s birth weight. Using multivariate modeling, we identified severalconfounders: parity (multipara mothers delivered heavier babies compared to first-time mothers) explained as much as 24% of variation in birth weight ( p = 0.005), maternal height explained 20.7% ( p = 0.014), gestational age accounted for 19.7% ( p = 0.027), and maternal body mass index explained 19.1% ( p = 0.023) of the variation in the infant’s birth weight. Maternal serum insulin and infant’s sex were not observed to be associated with birth weight ( p = 0.342 and 0.669, respectively) in the overall model. Conclusion: Overweight/obese women may experience higher incidence of delivering larger babies. Multivariable regression analyses showed that maternal body mass index and height, parity, and gestational age are associated with newborn’s birth weight.

ABSTRACT Objective: To investigate whether tri-ponderal mass index and body mass index Z scores are equivalent for screening children and adolescents with insulin resistance. Methods: Cross-sectional study with 296 children and adolescents enrolled at public schools of Vitória, Espírito Santo, Brazil, aged eight to 14 years. The tri-ponderal mass index was calculated as the ratio between weight and height cubed. The body mass index was calculated as the ratio between weight and height squared. Insulin resistance was defined with the homeostatic model assessment (HOMA-IR). Results: The HOMA-IR was higher in the 4th quartile of body mass index Z scores and tri-ponderal mass index compared to 1st and 2nd quartiles for both girls and boys. The areas under the age-adjusted receiver operating characteristic curves were similar between the indices for girls (body mass index Z scores=0.756; tri-ponderal mass index=0.763) and boys (body mass index Z scores=0.831; tri-ponderal mass index=0.843). In addition, according to the simple linear regression analyses estimations, both body mass index Z scores and tri-ponderal mass index explained a significant fraction of the homeostatic model assessment variability for girls (body mass index Z scores: R2=0.269; tri-ponderal mass index: R2=0.289; p<0.001) and boys (body mass index Z scores: R2=0.175; tri-ponderal mass index: R2=0.210; p<0.001). Conclusions: The tri-ponderal mass index and body mass index Z scores were similar to discriminate children and adolescents with insulin resistance. It is noteworthy that the use of tri-ponderal mass index is clearly advantageous, because it can be calculated with no concerns on adjustments for the age, a fact that makes it very applicable in the clinical practice.

The Relationship

Abstract:To elucidate the effect of early growth patterns on the metabolic sensitivity to adiposity, we examined the relationship between the homeostatic model assessment of insulin resistance (HOMA-IR) and body mass index (BMI) levels at 12 years of age in 101 boys and 91 girls in a birth cohort. Children with an increase in BMI from the ages of 1.5 to 3 years exhibited a greater increase of HOMA-IR per BMI increase at 12 years of age compared to those with a decrease in BMI or stable BMI from 1.5 to 3 years. This suggests that children who show an increase in BMI from 1.5 to 3 years, a period normally characterized by a decreased or stable BMI, are more prone to developing insulin resistance at 12 years of age.

Negative Effekte

Zusammenfassung Hintergrund Diabetes mellitus Typ 2 (T2DM) und Sarkopenie nehmen mit steigendem Alter in ihrer Prävalenz zu und können langfristig betrachtet jeweils zu erheblichen gesundheitlichen und funktionellen Einschränkungen führen. Während eine zunehmende Insulinresistenz bei abnehmender Muskelmasse plausibel erscheint, sind umgekehrt auch glukotoxische negative Effekte auf die Skelettmuskulatur im Sinne einer sekundären Sarkopenie denkbar. Ziel dieser Arbeit war es, den Zusammenhang zwischen Sarkopenie, Insulinresistenz und T2DM bei älteren Menschen zu untersuchen. Methoden Untersucht wurden 1555 Probanden der Berliner Altersstudie II (BASE-II) mit einem durchschnittlichen Alter von 68 ± 4 Jahren. Die Diagnose T2DM wurde basierend auf der Anamnese sowie oralem Glukosetoleranztest und HbA1c-Wert nach ADA-Kriterien gestellt und die Insulinresistenz wurde via Homeostatic Model Assessment for Insulin resistance (HOMA-IR) und Insulinsensitivitätsindex nach Matsuda (ISI) eingeschätzt. Die appendikuläre Skelettmuskelmasse (ALM) wurde mittels Dual-Röntgen-Absorptiometrie (DXA) und eine Sarkopenie mithilfe der anhand des Body-Mass-Index (BMI) korrigierten Muskelmasse (ALM/BMI) nach den Cut-off-Werten des FNIH Sarcopenia Project bestimmt. Gruppenvergleiche wurden mittels Kruskal-Wallis-Test berechnet, und der Zusammenhang zwischen Diabetes mellitus und Sarkopenie bzw. ALM und Insulinresistenz wurde mittels geeigneter Regressionsmodelle überprüft. Ergebnisse 25,2 % der insgesamt 160 Probanden mit T2DM hatten bereits eine Sarkopenie. Sarkopenisch-adipöse Probanden wiesen im Vergleich zu nur adipösen, nur sarkopenen oder weder adipösen noch sarkopenen Probanden im Median einen niedrigeren ISI und einen höheren HOMA-IR auf (jeweils p < 0,001). T2DM zeigte sich unabhängig assoziiert mit Sarkopenie (OR 3,293, 95 %-KI 1,984–5,466, p < 0,001), während nach Ausschluss bekannter Diabetiker eine höhere ALM mit einem höheren ISI (B 0,229, 95 %-KI 0,119–0,338; p < 0,001), nicht jedoch niedrigerem HOMA-IR (B –0,017, 95 %-KI –0,089–0,055; p = 0,640) einherging. Diskussion Sarkopenie ist sowohl mit Insulinresistenz als auch T2DM assoziiert. Die Frage bzgl. der Kausalität ist aufgrund des querschnittlichen Designs der Studie nicht zu beantworten, jedoch sollte eine mögliche Rolle des T2DM als sekundäre Sarkopenieursache berücksichtigt und weiter untersucht werden. Im Hinblick auf mögliche Folgen erscheinen die Identifizierung von Risikopatienten mit kombiniertem Auftreten von Sarkopenie und Insulinresistenz und die Evaluation basaler präventiver Maßnahmen wie gezieltes körperliches Training und angepasste Ernährung ein weiterführendes sinnvolles Ziel.

Discordant Twins

AbstractBackground:Insulin resistance (IR) in adults has been associated with intrauterine growth restriction (IUGR). Leptin and adiponectin correlations with anthropometric parameters and IR at 72 h in discordant twins were tested.Methods:We included 24 discordant (birth weight discordance ≥20% in relation to the heavier cotwin) and 30 concordant (birth weight discordance ≤10%) twins.Results:A correlation between leptin (but not adiponectin) level and birth weight (BW), birth length and head circumference in IUGR twins was recorded (p<0.05). Insulin sensitivity (IS) and homeostatic model assessment (HOMA)-IR in IUGR twins were similar to appropriate-for-gestational-age cotwins and unrelated to adipokines. In IUGR twins, adiponectin and insulin associated positively. In larger concordant twins’ leptin level correlated with HOMA-IR and insulin.Conclusions:Leptin, but not adiponectin, levels correlate positively with anthropometric parameters in IUGR twins. IR in IUGR twins is unrelated to adipokines in the first few days of life.

Abstract Introduction: Insulin resistance (IR) develops as early as age 1 to 3 yr in small for gestational age (SGA) infants who show rapid catch-up postnatal weight gain. In contrast, greater insulin secretion is related to infancy height gains. We hypothesized that IGF-I levels could be differentially related to gains in length and weight and also differentially related to IR and insulin secretion. Methods: In a prospective study of 50 SGA (birth weight &lt; 5th percentile) and 14 normal birth weight [appropriate for gestational age (AGA)] newborns, we measured serum IGF-I levels at birth, 1 yr, and 3 yr. IR (by homeostasis model assessment) and insulin secretion (by short iv glucose tolerance test) were also measured at 1 yr and 3 yr. Results: SGA infants had similar mean length and weight at 3 yr compared with AGA infants. SGA infants had lower IGF-I levels at birth (P &lt; 0.0001), but conversely they had higher IGF-I levels at 3 yr (P = 0.003) than AGA infants. Within the SGA group, at 1 yr IGF-I was associated with length gain from birth and insulin secretion (P &lt; 0.0001); in contrast at 3 yr IGF-I was positively related to weight, body mass index, and IR. Conclusions: IGF-I levels increased rapidly from birth in SGA, but not AGA children. During the key first-year growth period, IGF-I levels were related to β-cell function and longitudinal growth. In contrast, by 3 yr, when catch-up growth was completed, IGF-I levels were related to body mass index and IR, and these higher IGF-I levels in SGA infants might indicate the presence of relative IGF-I resistance.

Abstract Objectives Madhumeha Kusumakar Rasa (MKR) is an Ayurved formulation having a strong pharmacological base for diabetes management. This study aimed to validate MKR's efficacy in dexamethasone-induced insulin resistance (IR). Methods Albino Wistar rats were divided into four groups. Group 1 served as the normal control, Group 2 received dexamethasone 1.5 mg/kg (i.p.), Group 3 received dexamethasone and metformin 200 mg/kg (p.o.), and Group 4 received dexamethasone and MKR 236 mg/kg (p.o.). Animals were evaluated for serum glucose levels and glucose tolerance, serum insulin, Homeostatic model assessment of insulin resistance (HOMA-IR), Homeostatic model assessment of insulin sensitivity (HOMA-IS), fasting glucose to insulin ratio (FGIR), and lipid parameters. Pancreas, liver, and kidneys were evaluated for reduced Glutathione (GSH) and Malondialdehyde (MDA) levels. These tissues were also evaluated for histopathological changes. Results MKR showed significant improvement in serum glucose and glucose tolerance, serum insulin and HOMA-IR, HOMA-IS, and FGIR. It also showed a significant improvement in lipid parameters as compared to the dexamethasone-treated group. It prevented depletion of GSH levels and elevation in MDA levels. These effects were supported by histopathological analysis. Conclusions MKR treatment significantly attenuated dexamethasone-induced IR. This study validates the mechanism of the anti-diabetic potential of MKR.

AbstractBackgroundThe obesity epidemic is a pressing global health concern, as obesity rates continue to climb worldwide. The current study was aimed mainly to evaluate the correlation between thyroid hormones and homeostatic model assessment of insulin resistance in Saudi obese women with metabolic syndrome.Methods100 obese women aged 25 to 55 years were clinically evaluated, from which 72 women were diagnosed with the metabolic syndrome and 28 without metabolic syndrome. Insulin resistance was quantified using the homeostatic model assessment of insulin resistance method and the resulting values were analyzed for association with demographic, clinical, and metabolic parameters.ResultsThis analysis revealed that body mass index, systolic blood pressure, and biochemical parameters and fasting insulin showed statistically higher levels in the group with metabolic syndrome compared to the group without metabolic syndrome. Similarly, values of waist circumference, fat ratio, cholesterol, free thyroxine, free triiodothyronine and homeostatic model assessment of insulin resistance results were higher in the group with metabolic syndrome as compared to the group without metabolic syndrome. Correlation analysis revealed positive association of thyroid-stimulating hormone with waist circumference (P=0.01), total cholesterol (P=0.002), fasting insulin (P=0.03) and homeostatic model assessment of insulin resistance results (P<0.01), and negatively associated with diastolic blood pressure (P=0.013) and age (P=0.05). Free thyroxine was positively associated with triglyceride level (P=0.003) and negatively associated with homeostatic model assessment of insulin resistance values (P=0.035) and fasting insulin. Free triiodothyronine was positively associated with body mass index (P=0.032) and waist circumference (P= 0.006) and negatively with age (P=0.004) and total cholesterol (P=0.001).Homeostatic model assessment of insulin resistance test revealed elevated level with positive association of body mass index, waist circumference, biochemical parameters and thyroid-stimulating hormone in insulin resistant obese women. Higher level of free triiodothyronine was found to be associated with low insulin sensitivity.

The present study aims to detect several biochemical markers associated with PCOS (Polycysticovary syndrome) in Iraqi women comparing the results with control normal fertile women andalso studying the effect of obesity on the same biochemical markers. Ninety eight women withPCOS, 51 non-obese [body mass index (BMI) less than 25 kg/m2] and 47 obese (BMI >25 kg/m2)were enrolled for the study. Each group of them was compared forty normal fertile women ascontrol group matched for each in age and BMI. The first part of this study was devoted to themeasurement of Body Mass Index (BMI) and Waist Hip Ratio (WHR), subdivided PCOSaccording to the body mass index, and measurement of fasting insulin, fasting glucose,Homeostatic Model Assessment (HOMA), HbA1c and lipid profile. A significant differences wasfound in HbA1c (P≤0.0001) VLDL (p≤0.0001), triglyceride (p≤0.05) and cholesterol (p≤0.05)between obeses and lean PCOS patients. Insulin serum level (P≤0.0001) was highly significantlyincreased in obeses PCOS patients as compared to obeses control, the serum insulin (P≤0.0001)also significantly increased in lean PCOS women when compared with lean control. There was asignificant differences between HOMA (P≤0.05) in obeses PCOS patients than in the obesecontrol group and between obese and lean women PCOS patients.
