Abstract Background: The MC4R gene harbours one of the strongest susceptibility locus for obesity, and its metabolic consequences. The objective of this study was to analyze whether dietary factors may attenuate the MC4R genotypes effects on obesity and its comorbidities.Methods: In 819 adult participants, genotyped for MC4R SNPs (rs17782313, rs12970134, rs633265, rs1350341) the anthropometric measurements, total body fat, visceral (VAT) and subcutaneous adipose tissue (SAT), blood glucose, insulin, total-, LDL-, HDL-cholesterol, and triglycerides concentrations were assessed. The daily macronutrient intake was calculated based on the three-day food intake records, and daily physical activity based on the validated questionnaire. The ANOVA or Kruskal-Wallis tests were used, and multivariate linear regression models were developed to evaluate the effects of diet on obesity and related factors in various genotypes carriers.Results: The CC genotype (rs17782313) carriers, being in the upper quantiles of protein intake, presented significantly higher VAT, VAT/SAT ratio, fasting blood glucose and triglyceride concentrations, and an increase of energy derived from proteins was associated with significantly higher BMI (Est. 5.74, R2=0.12), body fat content (Est. 8.44, R2=0.82), VAT (32.59, R2=0.06), and VAT/SAT ratio (Est. 0.96, R2=0.05). The AA genotype carriers (rs12970134) being in the upper protein intake quantiles presented higher BMI, body fat, SAT and VAT volume, waist circumference, fasting blood glucose, triglycerides and total cholesterol concentrations. Individuals carrying the AG and GG genotypes in the upper carbohydrate intake quantile had significantly lower body weight, waist circumference, insulin resistance and fasting insulin levels. An increase of energy derived from proteins by AA carriers was associated with significantly higher VAT (Est. 19.95, R2=0.06) and VAT/SAT ratio (Est. 0.64, R2=0.05).Conclusions: Our findings provide evidence that associations of the common MC4R SNPs with obesity and its comorbidities is modulated by dietary intake, and may be useful for genome-customized diets for obesity prevention.Trial registration. This trial was registered at www.clinicaltrials.gov as NCT03792685. Date of registration: 3Jan2019 (retrospectively registered), https://clinicaltrials.gov/ct2/show/NCT03792685.

The melanocortin-4 receptor (MC4R) gene harbours one of the strongest susceptibility loci for obesity and obesity-related metabolic consequences. We analysed whether dietary factors may attenuate the associations between MC4R genotypes and obesity and metabolic parameters. In 819 participants genotyped for common MC4R polymorphisms (rs17782313, rs12970134, rs633265, and rs135034), the anthropometric measurements, body fat content and distribution (visceral and subcutaneous adipose tissue, VAT and SAT, respectively), and blood glucose, insulin, total-, LDL-, HDL-cholesterol, triglycerides concentrations, and daily macronutrient intake were assessed. ANOVA or Kruskal–Wallis tests were used, and multivariate linear regression models were developed. We observed that the CC genotype carriers (rs17782313) presented higher VAT, VAT/SAT ratio, fasting blood glucose and triglyceride concentrations when they were stratified to the upper quantiles of protein intake. An increase in energy derived from proteins was associated with higher BMI (Est. 5.74, R2 = 0.12), body fat content (Est. 8.44, R2 = 0.82), VAT (Est. 32.59, R2 = 0.06), and VAT/SAT ratio (Est. 0.96, R2 = 0.05). The AA genotype carriers (rs12970134) presented higher BMI, body fat, SAT and VAT, fasting blood glucose, triglycerides and total cholesterol concentrations. An increase in energy derived from proteins by AA carriers was associated with higher VAT (Est.19.95, R2 = 0.06) and VAT/SAT ratio (Est. 0.64, R2 = 0.05). Our findings suggest that associations of the common MC4R SNPs with obesity and its metabolic complications may be dependent on the daily dietary intake, which may open new areas for developing personalised diets for preventing and treating obesity and obesity-related comorbidities.

Objectives. The study aimed to assess the relationship between body fat and each of body mass index (BMI) and waist circumference (WC), and to test the effectiveness of fat mass (FM), percent of body fat (PBF), BMI, and WC in predicting high levels of fasting blood glucose (FBG).Methods. A total of 167 adolescents aged 11–17 years were recruited from Rabat region. BMI and WC were determined using standard equipments. FM and PBF were derived from isotope dilution technique. FBG was determined by the hexokinase method.Results. Regardless of the weight status, BMI showed a strong positive correlation with FM and PBF in both genders. WC was significantly correlated with FM in boys and girls, and with PBF in different groups of girls and boys of the study sample. However, there was no significant relationship between WC and PBF in normal weight and overweight-obese groups of boys. FBG was highly correlated with FM and PBF in girls of the study sample and in overweight-obese girls. Similar significant relationship between FBG and both BMI and WC was observed in overweight-obese girls, while there was no significant association between FBG and other variables in boys and normal-weight girls.Conclusion. BMI and WC were closely associated with FM and PBF, respectively. However, the degree of these associations depends on gender and weight status. BMI may provide a better proxy estimate of overall adiposity than WC; nevertheless, both of them would appear to be a reasonable surrogate for FM and PBF as screening tools to identify adolescents at risk of developing excess body fat and high level of FBG.

Background: Few research studies have focused on the effects of dietary protein on metabolic syndrome and its components. Our objective was to determine the relationship between the type of dietary protein intake and animal to plant (AP) protein ratio with metabolic syndrome and its components. Methods: This population-based study had a cross sectional design and conducted on 518 participants of the Adventist Health Study 2 (AHS-2) Calibration Study. Two sets of three dietary 24-h recalls were obtained six months apart. Anthropometric measures and biochemical tests were performed in clinics. Regression calibration models were used to determine the association of type of dietary protein with metabolic syndrome and its components (raised triglyceride, raised blood pressure, reduced high-density lipoprotein cholesterol (HDL), raised fasting blood glucose and increased waist circumference). Results: The likelihood of metabolic syndrome was lower in those with higher total dietary protein and animal protein intake (p = 0.02).Total protein (β = 0.004, [95%CI: 0.002, 0.007]), animal protein intake (β = 0.004, [95%CI: 0.001, 0.007]) and AP protein intake ratio (β = 0.034, [95%CI: 0.021, 0.047]) were positively associated with waist circumference. Higher AP protein ratio was related to higher fasting blood glucose (β = 0.023, [95%CI: 0.005, 0.041]). Conclusion: Our study suggests that considering a significant amount of plant protein as a part of total dietary protein has beneficial effects on cardiometabolic risk factors.

Background: Cardiometabolic disease risk is increasing in the premenopausal phase of women life. This study aims to relationship body fat percentage with the modifiable risk factors of cardiometabolic disease in Minangkabau premenopausal people. Methods: A cross-sectional study was conducted in 111 Minangkabau premenopausal people, aged 40 – 55 years old at Padang City in West Sumatera, Indonesia. Body fat percentage analyzed by Bioelectrical Impedance Analyzer (BIA). Fasting blood glucose and lipid profile was examined from venous blood. Data were analyzed by using a Rank-Spearman correlation test with significant levels p<0.05. Results:Average body fat percentage of subjects 36.23 ± 6.9, fasting blood glucose 101.52 ± 12.3 mg/dL; total cholesterol 193.99±41.5 mg/dL; triglyceride 113.76±37.9 mg/dL mg/dL; LDL-cholesterol 120.59±45.7 mg/dL and HDL-cholesterol 53.52±15.6 mg/dL. Body fat percentage has a significant correlation with triglyceride (r=0.368; p=0.001), and HDL-cholesterol levels (r=-0.307; p=0.006 ) just in subject with polymorphism, but does not have a significant correlation with another biomarker. Conclusion: Body fat percentage correlates with triglyceride and HDL cholesterol in Minangkabau premenopausal women who have polymorphism of TERT Gene. BACKGROUND: Cardiometabolic disease risk is increasing in the premenopausal phase of women life. The telomerase reverse transcriptase (TERT) gene is a gene that plays a role in protecting telomeres from progressive shortening. Telomere shortening is associated with the incidence of cardiometabolic disease. AIM: This study aims to elucidate the relationship body fat percentage with the modifiable risk factors of cardiometabolic disease in Minangkabau premenopausal people. METHODS: A cross-sectional study was conducted in 111 Minangkabau premenopausal people aged 40–55 years old at Padang City in West Sumatera, Indonesia. Body fat percentage analyzed by bioelectrical impedance analyzer. Fasting blood glucose and lipid profile were examined from venous blood. Polymorphism of the TERT rs2736098 gene was analyzed by a polymerase chain reaction. Data were analyzed using Spearman’s rank correlation test with significant levels p < 0.05. RESULTS: Average body fat percentage of subjects was 36.23 ± 6.9, fasting blood glucose was 101.52 ± 12.3 mg/dL; total cholesterol was 193.99 ± 41.5 mg/dL; triglyceride was 113.76 ± 37.9 mg/dL; LDL-cholesterol was 120.59 ± 45.7 mg/dL and HDL-cholesterol was 53.52±15.6 mg/dL. Body fat percentage has a significant correlation with triglyceride (r = 0.368; p = 0.001) and HDL-cholesterol levels (r = −0.307; p = 0.006) just in subject with polymorphism but does not have a significant correlation with another biomarker. CONCLUSION: Body fat percentage correlates with triglyceride and HDL cholesterol in Minangkabau premenopausal women who have polymorphism of TERT gene.

Objective:Traditionally prepared infusions and decoctions are commonly used in the management of diabetes mellitus, in southern Nigeria; one of such is the aqueous extract of the sclerotia of Pleurotus tuberregium (“usu” milk). In this study, the effects of the extract on the body weights, tissue/ organ weights, fasting blood glucose, blood/plasma lipid profiles and atherogenic indices were investigated in normal and alloxan-induced diabetic rabbits.Methods:Diabetes mellitus was induced by the injection of alloxan (120 mg/kg body weight) via the marginal ear vein. The extract was administered orally at 100, 200 and 300 mg/kg to normal and diabetic rabbits; while metformin was administered at 50 mg/kg. The crude extract was analyzed by gas chromatography, coupled to flame ionization detector.Results:Thirty-one known flavonoids were detected, consisting mainly of isoquercetin (28.5%), luteolin (24.3%), quercetin (18.8%) and kaempferol (11.3%). Sitosterol (82.0%) and stigmasterol (12.5%) were the most abundant of the seven phytosterols detected. Compared to the diabetic control, the treatment significantly (p<0.05) lowered the weights of the kidney and liver, as well as the levels of blood glucose and triglyceride, plasma VLDL, LDL and non-HDL cholesterol, atherogenic index of plasma, cardiac risk ratio, atherogenic coefficient and Castelli’s risk index II. It, however, significantly (p<0.05) increased plasma HDL cholesterol, without significantly affecting blood total cholesterol levels.Conclusion:This study showed that the extract was hypoglycemic, and improved lipid profile and atherogenic indices, thus highlighting its cardioprotective potential, thereby supporting its use in the management of diabetes mellitus.

Abstract Objective Arterial hypertension (HTN) is one of the most common diseases associated with obesity. Visceral obesity (VO) with dysfunctional visceral adipose tissue plays the main role in obesity induced HTN. Direct criteria of VO including echocardiographic epicardial fat thickness (EFT) may become an additional predictor of HTN. Purpose The aim was to assess the role of echocardiographic EFT (EEFT) as a predictor of HTN in normotensive patients with abdominal obesity (AO). Methods 526 normotensive men (according to ambulatory blood pressure monitoring (ABPM) without therapy) with AO (waist circumference (WC) &gt;94 cm) and SCORE &lt;5%, without cardiovascular diseases and diabetes mellitus were examined (age 45.1±5.0 years). The lipid and glucose profiles, creatinine, uric acid and C-reactive protein blood levels, albuminuria evaluation, echocardiography, carotid ultrasound, bifunctional ABPM were performed. The values of EEFT ≥75 percentile for persons 35–45 years and 46–55 years were 4.8 mm and 5.8 mm respectively. These values used as epicardial VO criteria. Patients with subclinical carotid atherosclerosis due to the lipid-lowering therapy administration (n=98) were excluded from the follow-up. Re-examination with ABPM was conducted on average through 46.3±5.1 months. Data were summarized as mean ± standard error, statistical analysis conducted with paired two-tailed t-tests, Pearson χ2 criterion and multivariate regression analysis. Results Data of 406 persons were available for analysis. HTN as average daily blood pressure ≥130/80 mm Hg was detected in 157 (38.7%) patients. These patients were characterized by initially higher values of age (45.9±4.6 years vs 44.3±4.9 years, p&lt;0.001), waist circumference (106.9±7.3 cm vs 104.2±7.3 cm, p&lt;0.001), body mass index (BMI) (32.0±3.3 kg/m2 vs 30.9±3.2 kg/m2, p&lt;0.001), average daily systolic and diastolic blood pressure (120.7/74.5±4.6/3.4 mm Hg vs 118.2/73.2±5.5/3.9 mm Hg, p&lt;0.001), EEFT (5.2±0.7 mm vs 4.4±1.0 mm, p&lt;0.001). The epicardial VO was initially detected in 95 (23.3%) patients. In patients with HTN the initial prevalence of epicardial VO was greater (58.0% vs 23.3%, p&lt;0.001). As predictors for the multivariate regression analysis the clinical and laboratory examinations data and EEFT were evaluated. According to the results a mathematical model for estimating the probability HTN was obtained: 0.696*fasting blood glucose + 0.198*systolic BP + 2.844*EFT – 40.166 (constant). Among these predictors EEFT was characterized by the highest standardized regression coefficient (0.302, p&lt;0.001) (0.295, p&lt;0.01 for fasting blood glucose, 0.035, p&lt;0.001 for systolic BP). The Hosmer-Lemeshow test value was 0.863, the total percentage of correct classifications was 86%, the area under the ROC-curve was 0.913. Conclusions EEFT (4.8 mm for persons 35–45 years and 5.8 mm for persons 46–55 years) may be an additional predictor of HTN in normotensive patients with AO.

Metabolic syndrome can be found on an individual with normal weight (Metabolically Obese Normal Weight/MONW). Eating habits and lifestyle changing in early adulthood can be the risk of metabolic syndrome in person with a normal body mass index (BMI). The purpose of this study was to identify metabolic characteristics in women with normal BMI and to analyze the correlation of nutrition intake with metabolic syndrome on women with normal BMI. This is an observational study with a cross-sectional design at five offices in Semarang. The sample in this study was 64 subjects. Inclusion criteria of study subject were women aged 25-40 years and BMI <25 kg/m2 . Study subject was chosen by using a consecutive sampling method. The data of nutrition intake was obtained by using the Food Frequency Questionnaire. HDL cholesterol, fasting blood glucose and triglyceride were analyzed. Analysis data was conducted by using Pearson correlation and Rank Spearman. MONW was present in 10.9% and more than 50% had pre metabolic syndrome. A total of 51.6% of the subjects had central obese and 26.6% had low HDL cholesterol. About 14.1% of the subjects have hypertension. There was a positive correlation between energy, fat intake and waist circumference. Carbohydrate intake was positively correlated with fasting blood glucose and triglyceride. The higher protein intake, the higher HDL cholesterol. The most common indicator of metabolic syndrome on women with normal BMI was central obesity and low HDL cholesterol. The factors related to the prevalence of metabolic syndrome on women with normal BMI was macronutrient intake.

Objective: This study was aimed to determine the correlation between vitamin D and insulin resistance in women with PCOS. Method: This study was correlational analytic with cross-sectional approach to 34 women diagnosed with PCOS based on ultrasonography. Waist circumference and fasting blood glucose (FBG) represented insulin resistance. Women with hormonal therapy and vitamin D supplementation were not included to this study. This study used consecutive sampling method. Result: The average of age was 25.6±6.1 years old. Waist circumference and fasting blood glucose (FBG) represented insulin resistance. The average of waist circumference and FBG were 87.6±12.4 cm and 86.2±27.9 mg/dl, respectively. The mean of vitamin D levels was 11,5±3,6 ng/ml. According to Spearman’s correlation, vitamin D levels were weak negative correlated with waist circumference (r=-0.2; p>0.05) and FBG (r= -0,1; p>0,05), it statistically was not significant. Conclusion: There is weak negative correlation between vitamin D and metabolic syndrome in PCOS patients.

Both genetic and environmental factors play role in the pathogenesis of the metabolic syndrome. The magnitude of genetic and environmental influences on the components of metabolic syndrome may vary in different populations. Aims: The present study was aimed to determine the effects of genetic and environmental factors on risk factors characteristic for the metabolic syndrome. Methods: A total of 101 (63 monozygotic and 38 dizygotic) adult twin pairs (n = 202; mean age: 43.3±15.8 years) were investigated. Medical history was recorded and physical examination was carried out for each subject. Fasting venous blood samples were used for measuring laboratory parameters. The presented estimates include the heritability structural equation (A-C-E) model results. In Model-1, all presented parameters are age- and gender- corrected. In Model-2, parameters were corrected for age, gender, body mass index and waist circumference. Results: Heritability in waist circumference (as well as in other anthropometric parameters such as weight and height) was high (Model-1: 71.0–88.1%). Similarly, genetic factors had the highest proportion of total phenotypic variance in systolic and diastolic blood pressure (Model-2: 57.1% and 57.7%, respectively). Based on the results of Model-2, unique environmental factors dominate alterations in serum triglycerides values (55.9%) while shared environmental factors proved to be substantial in alterations of HDL-cholesterol and fasting blood glucose values (58.1% and 57.1%, respectively). Comparing the results of Model-1 and Model-2, the difference in A-C-E model varied from 0.0% to 17.1%, indicating that only a minor proportion of genetic and environmental influences can be explained by the effects of anthropometric parameters. Conclusions: Among adult Hungarian healthy people, genetic factors have substantial influence on waist circumference and blood pressure values while environmental factors dominate alterations in serum triglycerides, HDL-cholesterol and fasting blood glucose values. The different heritability of individual risk factors challenges the original unifying concept of the metabolic syndrome. The results may be useful for establishing and implementing primary cardiovascular prevention both at individual and population levels. Orv. Hetil., 2011, 152, 1265–1271.
