White rice consumption is a risk factor for metabolic syndrome in Tehrani adults: a prospective approach in Tehran Lipid and Glucose Study.

Consumption of white rice has been proposed as a dietary risk factor for development of metabolic disorders and type 2 diabetes, especially in populations who consume white rice as a staple food. In this study, we investigated the association between consumption of white rice and the occurrence of metabolic syndrome in Tehrani adults after 3 years of follow-up. This longitudinal study was conducted within the framework of the Tehran Lipid and Glucose Study on 1476 adults, aged 19-70 years. Dietary intakes were measured using a validated semi-quantitative food frequency questionnaire at baseline. Biochemical and anthropometric measurements were assessed and documented at baseline (2006-2008) and again 3 years later (2009-2011). Multiple logistic regression models were used to estimate the occurrence of the MetS in each quartile of white rice consumption. The mean age of participants was 37.8 ± 12.3 years, and mean BMI was 26.0 ± 4.5 Kg/m2 at baseline. Participants in the highest quartile of white rice consumption were significantly younger, had lower HDL-C levels, and higher systolic and diastolic blood pressures at baseline (P < 0.01). Higher consumption of white rice was also accompanied by higher increase in serum triglyceride levels after the 3-year follow-up (9.9 ± 2.3 vs. 8.2 ± 2.3%, P < 0.01). After adjustment for all potential confounders, the risk of metabolic syndrome in the highest quartile of white rice consumption compared with the lowest, was 1.66 (95% CI: 1.04-2.66). Moreover, participants with central obesity, low physical activity or low-fiber diet had greater risk of metabolic syndrome if white rice constituted ≥25.6% of total energy. We demonstrated that higher consumption of white rice may be a risk factor for development of metabolic syndrome among Iranian adults.

Metabolic syndrome reduces bone mineral density in overweight adolescents

Growing concern has focused on the occurrence of metabolic syndrome (MetS) and its effects on bone mass. There is little information available in the literature concerning the relationship between MetS and BMD in adolescents. The aim of this study was to evaluate the effects of MetS and its components on bone mineral density (BMD) in overweight adolescent boys and girls. This cross-sectional study assessed 271 overweight adolescents with or without MetS (age 10 to 16years). Anthropometric and biochemical tests were performed. Lumbar spine, proximal femur and total and subtotal body BMD values were obtained by bone densitometry with dual-energy X-ray absorptiometry. MetS was observed in 14% of the adolescents. Overweight adolescents of both genders who were positive for MetS presented with significant decreases in BMD (g/cm2/kg bodyweight) at all sites evaluated (p<0.01). Female adolescents with large waist circumference, low HDLc, hypertriglyceridemia and high blood pressure showed significant reductions in BMD at all sites evaluated (p<0.01) and, with the exception of increased triglycerides (which had no effect on BMD, p>0.05), the same pattern was observed in male adolescents. Linear regression analyses revealed that waist circumference was negatively correlated with BMD in both genders and that triglycerides were negatively correlated with BMD only in female adolescents. Our results suggest that overweight adolescents with MetS have lower BMD than adolescents without MetS. Among all MetS components measured, increased waist circumference had the strongest relationship with reductions in BMD.

Metabolic syndrome and nephrolithiasis: a systematic review and meta-analysis of the scientific evidence

The metabolic syndrome is a cluster of cardiometabolic alterations at least partly dependent on reduced insulin sensitivity and hyperinsulinemia that can have several renal implications. A systematic review and meta-analysis of studies available in the international literature in English language demonstrates that the metabolic syndrome occurrence is associated with a significantly higher prevalence of nephrolithiasis (odds ratio 1.29, 95% confidence intervals: 1.11-1.51). The pathophysiological bases of this association are currently not completely understood, however. Potential pathogenetic links between the two conditions include metabolic factors that promote insulin resistance as well as stone formation in urine, environmental factors such as diet, oxidative stress and inflammation, and molecular changes impacting the transport of some analytes in urine. Metabolic syndrome-related nephrolithiasis shows peculiar clinical and biochemical characteristics and should be considered a multifactorial systemic disorder needing a multidisciplinary approach for adequate prevention and management in pediatric and adult age.

Association of FTO , LEPR and MTHFR Gene Polymorphisms with Metabolic Syndrome in Schizophrenia Patients Receiving Antipsychotics

The occurrence of metabolic syndrome (MS) in schizophrenia patients receiving long-term antipsychotics (APs) contributes to their high mortality rate. We aimed to determine whether genetic polymorphisms of identified candidate genes are associated with MS in our study population. We recruited 206 schizophrenia patients receiving AP treatment for at least a year. Cross-sectional measurements of weight, height, blood pressure, waist and hip circumference, and other lipid profiles were recorded. Patient DNA was genotyped for 16 candidate gene polymorphisms. Of these patients, 59.7% were found to have MS while 40.3% did not. All metabolic parameters were significantly different between the two groups. Only three of the 16 polymorphisms studied showed significant association with MS; rs9939609 of the FTO gene confers risk for MS (odds ratio [OR]: 1.73, 95% CI: 1.07-2.78, p = 0.026), while rs1137101 of the LEPR gene (OR: 0.47, 95% CI: 0.28-0.80, p = 0.005) and rs1801133 of the MTHFR gene (OR: 0.59, 95% CI: 0.35-0.99, p = 0.049) are protective against MS. Polymorphisms of the FTO, LEPR and MTHFR genes may play a role in MS in Malaysian schizophrenia patients receiving long-term treatment with APs.

Endothelial and metabolic disorders in adolescence: low birth weight is not an isolated risk factor.

Low birth weight (LBW) seems to be a determining factor for many cardiovascular diseases in adult life. The objectives of this study were to investigate the occurrence of metabolic syndrome (MetS) and endothelial dysfunction in adolescents with LBW and compare them with subjects with normal birth weights (NBW). This retrospective cohort study evaluated 172 adolescents (86 in each group) aged 10-20 years, who were born in a reference maternity hospital. The following criteria were adopted: International Diabetes Federation parameters for the diagnosis of MetS and flow-mediated brachial artery dilatation for endothelial dysfunction. Student's t-test or Mann-Whitney tests were used for continuous variables (depending on the normality of distribution evaluated by the Shapiro-Wilk test), and the Fisher exact test was used for categorical variables. The significance level was determined at 0.05. MetS was present in three cases of LBW and in four cases of NBW (p=0.70). The number of components of the syndrome was, on average, 0.6 and 0.5 in LBW and NBW, respectively (p=0.77). Endothelial dysfunction occurred in 25 (29.1%) cases of LBW and in 31 (36.1%) cases of NBW (p=0.33). LBW did not represent a risk factor in the occurrence of MetS or endothelial dysfunction in adolescence.

A-FABP Concentration Is More Strongly Associated with Cardiometabolic Risk Factors and the Occurrence of Metabolic Syndrome in Premenopausal Than in Postmenopausal Middle-Aged Women

We aimed at the evaluation of the relationship between adipocyte fatty acid binding protein (A-FABP) and cardiometabolic risk factors in premenopausal and postmenopausal women. Additionally, we compared A-FABP with adipokines related to metabolic syndrome (MetS) such as leptin and adiponectin. 94 premenopausal and 90 early postmenopausal middle-aged Caucasian women were subject to examinations. Postmenopausal women had higher A-FABP than premenopausal; this difference became insignificant after controlling for age. We found significantly higher correlation coefficients between A-FABP and TC/HDL-C ratio and number of MetS components in premenopausal women, compared to postmenopausal. Each 1 ng/dL increase in A-FABP concentration significantly increased the probability of occurrence of atherogenic lipid profile in premenopausal women, even after multivariate adjustment. All odds ratios became insignificant after controlling for BMI in postmenopausal women. A-FABP was more strongly associated with MetS than leptin and adiponectin in premenopausal women. Adiponectin concentration was a better biomarker for MetS after menopause. Our results suggest that the A-FABP is more strongly associated with some cardiometabolic risk factors in premenopausal than in postmenopausal women. Higher values of A-FABP after menopause are mainly explained by the fact that postmenopausal women are older. Because of the limitation of study, these results should be interpreted with caution.

The Effect of Bergamot-Derived Polyphenolic Fraction on LDL Small Dense Particles and Non Alcoholic Fatty Liver Disease in Patients with Metabolic Syndrome

The occurrence of Metabolic Syndrome (MS) represents an independent risk factor for developing cardiovascular disease states in patients suffering from type 2 diabetes mellitus. Moreover, both the size of LDL particles and liver dysfunction identified as non alcoholic fatty liver disease (NAFLD) represent important biomarkers for the development of cardiometabolic risk in patients with MS. Here we studied the effect of bergamot polyphenolic fraction (BPF) in patients with MS and NAFLD. 107 patients were enrolled at the San Raffaele IRCCS (Rome). All of them showed ultrasonografic evidences of NAFLD and at least three out of five previous identified criteria for the diagnosis of MS. Patients were divided into two groups: one receiving placebo and the second receiving BPF 650 mg twice a day for 120 consecutive days. In the group receiving BPF 650 mg twice a day, a significant reduction of fasting plasma glucose, serum LDL cholesterol and triglycerides alongside with an increase of HDL cholesterol was found. This effect was accompanied by significant reduction of both ultrasonographic and metabolic biomarkers of NAFLD. Moreover, a significant reduction of small dense LDL particles, as detected via proton NMR Spectroscopy, was found after BPF treatment. In conclusion, our data confirm the beneficial effect of bergamot-extract in patients with MS an effect highlighted by significant reduction of small dense LDL particles and by improvement of NAFLD biomarkers. This suggests a potential preventive role of bergamot derivatives in reducing cardiometabolic risk.

Lipogenic metabolism: a viable target for prostate cancer treatment?

Cancer cells often depend on altered metabolism compared with their normal counterparts.1234 As observed in 1924 by Otto Warburg, cancer cells show preferential glucose consumption by way of aerobic glycolysis while normal cells generally assume mitochondrial oxidative phosphorylation.4 Another metabolic hallmark of carcinogenesis is altered lipid metabolism, whereby cancer cells may adopt enhanced de novo lipid production (lipogenesis).123 Enhanced lipid metabolism is also observed in individuals with metabolic syndromes potentially a consequence of increasing popularity of the Standard American Diet, composed of high levels of saturated fats and carbohydrates.5 A growing body of epidemiological data indicates a positive correlation between the occurrence of metabolic syndromes, such as cardiovascular disease, obesity, type-2 diabetes and associated hyperinsulemia, with the aggressiveness of cancer.6789 Remarkably, it is estimated that for every 1% reduction in saturated fats, replaced by polyunsaturated, there would be a 2%–3% reduction in cardiovascular disease.10 Thus, it is conceivable that an equally remarkable attenuation in cancer progression might be achieved with such a reduction in lipid accumulation.

Adiposity Rebound and the Development of Metabolic Syndrome

The age of adiposity rebound (AR) is defined as the time at which BMI starts to rise after infancy and is thought to be a marker of later obesity. To determine whether this age is related to future occurrence of metabolic syndrome, we investigated the relationship of the timing of AR with metabolic consequences at 12 years of age. A total of 271 children (147 boys and 124 girls) born in 1995 and 1996 were enrolled in the study. Serial measurements of BMI were conducted at the ages of 4 and 8 months and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 years, based on which age of AR was calculated. Plasma lipids and blood pressure were measured at 12 years of age. An earlier AR (<4 years of age) was associated with a higher BMI (≥ 20) and a lipoprotein phenotype representative of insulin resistance. This phenotype consists of elevated triglycerides, apolipoprotein B, and atherogenic index and decreased high-density lipoprotein cholesterol in boys and elevated apolipoprotein B in girls at 12 years of age. The earlier AR was also related to elevated blood pressure in boys. This longitudinal population-based study indicates that children who exhibit AR at a younger age are predisposed to future development of metabolic syndrome. Therefore, monitoring of AR may be an effective method for the early identification of children at risk for metabolic syndrome.

Insulinooporność u dzieci

Insulin resistance is the state of reduced tissue sensitivity to insulin. The frequency of this occurrence is increasing dramatically in developed countries. Both, environmental and genetic factors are involved in the pathogenesis of insulin resistance. Sedentary lifestyle and the excessive calorie intake cause the substantial increase of the fat issue, leading to overweight and obesity. Insulin resistance occurs physiologically during puberty, but it is also a pathological condition predisposing children to develop abnormal glucose tolerance, diabetes, hypertension and polycystic ovary syndrome among girls. More frequent occurrence of metabolic syndrome can be observed among children born small for gestational age (SGA). The article presents the current views on risk factors, etiology, diagnosis and consequences insulin resistance and disorders of glucose tolerance.

Correlation of obstructive sleep apnea hypopnea syndrome with metabolic syndrome in snorers.

Though obstructive sleep apnea hypopnea syndrome (OSAHS) and metabolic syndrome (MS) are correlated; the contributing factors for the occurrence of MS in Chinese snorers remain largely undefined. We aimed to investigate the associated pathogenesis of coexistence of OSAHS and MS in Chinese snorers. A total of 144 Chinese habitual snorers were divided into 3 groups, the control group (simple snorers) (n = 36), the mild OSAHS group (n = 52) and the moderate-to-severe OSAHS group (n = 56). The incidence of MS in the moderate-to-severe OSAHS group (26.8%) was significantly higher than that in the control group (8.3%), the mild OSAHS group (11.1%) and all the OSAHS patients (19.45%) (all P < 0.05). Homeostatic model assessment (HOMA) index and proinsulin (PI) were negatively correlated with nocturnal meanSpO2 and miniSpO2. Meanwhile, nocturnal SpO2 were negatively correlated with body mass index, waist and neck circumferences and diastolic blood pressure, but positively correlated with total cholesterol and high-density lipoprotein cholesterol. The study indicated that in Chinese snorers, moderate-to-severe OSAHS was closely associated with MS via nocturnal hypoxemia.

Fast food consumption and the risk of metabolic syndrome after 3-years of follow-up: Tehran Lipid and Glucose Study

There are growing concern globally regarding fast food consumption and its related cardiometabolic outcomes. In this study we investigated whether fast food consumption could affect the occurrence of metabolic syndrome (MetS) after 3-years of follow-up in adults. This longitudinal study was conducted in the framework of Tehran Lipid and Glucose Study on 1476 adults, aged 19-70 y. The usual intakes of participants were measured using a validated semi-quantitative food frequency questionnaire at baseline. Biochemical and anthropometric measurements were assessed at baseline (2006-2008) and 3 years later (2009-2011). Multiple logistic regression models were used to estimate the occurrence of the MetS in each quartile of fast food consumption. The mean age of participants was 37.8±12.3 y, and mean BMI was 26.0±4.5 kg/m(2) at baseline. Participants in the highest quartile of fast food consumption were younger (33.7 vs 43.4 years, P<0.01). Higher consumption of fast food was accompanied with more increase in serum triglyceride levels and triglyceride to HDL-C ratio after the 3-year follow-up. After adjustment for all potential confounding variables, the risk of metabolic syndrome, in the highest quartile of fast foods compared with the lowest, was 1.85 (95% CI=1.17-2.95). The effects of fast food consumption on the occurrence of MetS were more pronounced in younger adults (<30 years), and participants who had greater wait to hip ratio, consumed less phytochemical-rich foods or had low-fiber diet (P<0.05). We demonstrated that higher consumption of fast foods had undesirable effects on metabolic syndrome after 3-years of follow-up in Iranian adults.

Effects of energy-dense nutrient-poor snacks on the incidence of metabolic syndrome: A prospective approach in Tehran Lipid and Glucose Study

ObjectivesIncreased consumption of energy-dense, nutrient-poor snacks is one of the major, growing concerns in relation to the alarming trend of overweight, obesity, and metabolic disorders worldwide. The aim of this study was to investigate whether consumption of energy-dense snacks could affect the occurrence of metabolic syndrome after 3 y of follow-up in adults. MethodsThis longitudinal study was conducted within the framework of the Tehran Lipid and Glucose Study between 2006 and 2008 and 2009 and 2011, on 1466 adults, ages 19 to 70 y. The usual intake of participants was measured using a validated semiquantitative food frequency questionnaire at baseline. Biochemical and anthropometric measurements were assessed at baseline and 3 y later. Multiple logistic regression models were used to estimate the occurrence of metabolic syndrome (MetS) in each quartile of energy-dense snacks. ResultsParticipants in the highest quartile of energy-dense snack consumption were significantly younger (33.8 versus 43.1 y; P < 0.01). There were non-significant increased risks for MetS in the highest quartile of biscuits and cakes (odds ratio [OR], 1.13; 95% confidence interval [CI], 0.77–1.66), and candies and chocolates (OR, 1.31; 95% CI, 0.88–1.94). The risk for MetS in participants with highest consumption of salty snacks increased more than 50% (OR, 1.56; 95% CI, 1.01–2.40). Consumption of soft drinks had a borderline effect on the risk for MetS. More than 361 kcal/d from total energy-dense snacks independently increased the occurrence of MetS in the fourth compared the first quartile category (OR, 1.53; 95% CI, 1.03–2.29). ConclusionThe findings of this study demonstrated that higher consumption of energy-dense snacks could be a dietary risk factor for development of MetS.

The Maternal Health Clinic: A New Window of Opportunity for Early Heart Disease Risk Screening and Intervention for Women with Pregnancy Complications

W cardiovascular health is a key national priority that should be addressed through improving cardiovascular awareness and prevention and reducing care inequities for women in general and younger women in particular.1–5 Given the costs of treating cardiovascular disease and screening for it, novel and innovative ways to identify women who should undergo cardiovascular risk screening, including biochemical testing, is critical to achieving this goal.

Association Between a 11β-Hydroxysteroid Dehydrogenase Type 1 Gene Polymorphism and Metabolic Syndrome in a South Indian Population

The striking phenotypic similarities between metabolic syndrome and the Cushing syndrome of glucocorticoid excess have often been linked to 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which activates inert precursors like the cortisone, 11-dehydrocortisone to active glucocorticoids by oxo-reductase activity in several organs. Thus, increased expression of 11β-HSD1 is associated with insulin resistance, diabetes, hypertension, and dyslipidemia. In this study, we investigated the association of a common polymorphism of the HSD11B1 gene with metabolic syndrome and its components. The study included 205 subjects, including 105 diagnosed with metabolic syndrome and 100 controls. The subjects were genotyped for the HSD11B1 gene polymorphism (rs12086634) T→G using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The distribution of the genotypes and its association with clinical and biochemical parameters were assessed. There was a significant association between the HSD11B1 gene polymorphism (rs12086634) and occurrence of metabolic syndrome compared to controls (P<0.0001). Regarding the rs1206634 T→G variant, heterozygous patients had a higher systolic blood pressure (P=0.039), higher prevalence of diabetes (P=0.010), and higher total cholesterol levels (P=0.006) compared to homozygotes. However, there was no significant association of the polymorphism with obesity or specific body habitus. We conclude that in a South Indian population, a polymorphism of the HSD11B1 gene containing the single-nucleotide polymorphism (SNP) rs12086634 T→G confers increased risk of metabolic syndrome.

Age dependence of association between metabolic syndrome and obesity among women

The study included 335 women aged 21-74. The results have shown that age is associated with the progressive accumulation of fat tissue and an increase in the waisttohip circumference ratio, which are mostly expressed in the second period of middle age. The ratio of the frequencies of gynoid and android spe� cies among overweight and obese women in the first and second period of middleaged groups and old age was 2.7 : 1; 1.3 : 1 and 0.2 : 1, respectively. The occurrence of metabolic syndrome in this age groups of women with gynoid species was 16.3, 18.9, and 30.0%; however, for android species, it was 62.5, 47.9, and 83.0%, respectively. Our results allow us to state that women with gynoid species are at the lowest risk for metabolic syndrome, even in old age.

Low level of serum sex hormone binding globulin is associated with the occurrence of metabolic syndrome

Objective To investigate the relationship between serum sex hormone binding globulin (SHBG)and metabolic syndrome (MS) in Chinese young population.Methods A total of 797 patients were enrolled and subdivided into MS group(n=377)and non-MS group(n =420).Body height and weight were measured for body mass index(BMI),and waist and hip circumstances for waist-to-hip ratio (WHR).Glutamate aminotransferase,aspartate aminotransferase,serum lipid level,fasting glucose and fasting insulin were determined.The level of serum SHBG was measured by chemiluminescent microparticle immunoassay.HOMA-IR was employed to evaluate the insulin sensitivity.Results The serum SHBG level of non-MS group was significantly higher than that in MS group[(34.97± 33.97 vs 19.54 ± 15.54) nmol/L,P＜0.001].After adjusted for age,sex,BMI,and WHR,serum SHBG level was negatively associated with diastolic blood pressure,fasting plasma glucose,fasting insulin,homeostasis model assessment for insulin resistance (HOMA-IR),and triglycerides (P ＜ 0.05),but it was significantly positively associated with HDL-C (P ＜ 0.001).After adjusted for age,sex,BMI,WHR,and HOMA-IR,binary logistic regression analysis showed that serum SHBG level was negatively associated with metabolic syndrome.Conclusions In Chinese young population,low level of serum SHBG is associated with the occurrence of metabolic syndrome.
