Peanuts contain bioactive substances that are beneficial for cardiovascular health. This three-arm, parallel-group randomised controlled trial (ARISTOTLE) and meta-analysis evaluated the beneficial effects of high-oleic peanuts and peanut butter in improving cardiometabolic health. Participants in the randomised controlled trial consumed 25 g of skin-roasted peanuts or 32 g of peanut butter, or a control butter made with peanut oil without fibre and polyphenols for six months. The skin-roasted peanuts group showed a reduction in total cholesterol/HDL-cholesterol and LDL-cholesterol/HDL-cholesterol ratios. The meta-analysis was highly heterogeneous in participant ethnicity, health status, peanut intervention dosage and duration. The dosage of peanuts, peanut butter and high oleic peanuts used was between 25 and 200 g/day. The participants were healthy, with metabolic syndrome (MeS), or at risk of MeS. There was a significant increase in body weight among those with or at risk of MeS. In addition, healthy participants showed reduced triglycerides, total cholesterol, and LDL-cholesterol/HDL-cholesterol ratios. Healthcare professionals can use the results of this research to understand the beneficial impact of peanut consumption on the lipid profile. However, further robust studies are required due to the high heterogeneity of the included studies in the meta-analysis.
Abstract
UNLABELLED Although numerous studies have reported the protective effect of nut consumption on cardiovascular risk, evidence for the role of peanuts in maintaining cardiometabolic health is inconclusive. Presented here are the results from the ARISTOTLE study, a parallel randomized controlled trial evaluating the impact of regular peanut intake on anthropometric, biochemical, and clinical measurements. The 63 healthy subjects that completed the study consumed their habitual diet plus either: a) 25 g/day of skin roasted peanuts (SRP, n = 21), b) two tablespoons (32 g)/day of peanut butter (PB, n = 23) or c) two tablespoons (32 g)/day of a control butter based on peanut oil (CB, n = 19) for 6 months. In addition, a meta-analysis of clinical trials, including data from the ARISTOTLE study, was carried out to update the evidence for the effects of consuming peanuts, including high-oleic peanuts, and peanut butter on healthy subjects and those at high cardiometabolic risk. After a systematic search on PubMed, Web of Science, Cochrane Library and Scopus databases up to July 2021, 11 studies were found to meet the eligibility criteria. In the ARISTOTLE study, lower total cholesterol/HDL-cholesterol and LDL-cholesterol/HDL-cholesterol ratios were found in the SRP group compared to the CB group (p = 0.019 and p = 0.008). The meta-analysis of clinical trials revealed that peanut consumption is associated with a decrease in triglycerides (MD: -0.13; 95% CI, -0.20 to -0.07; p < 0.0001) and that healthy consumers had lower total cholesterol and LDL-cholesterol/HDL-cholesterol ratios compared to the control groups (MD: -0.40; 95% CI, -0.71 to -0.09; p = 0.01 and MD: -0.19; 95% CI, -0.36 to -0.01; p = 0.03, respectively). However, individuals at high cardiometabolic risk experienced an increase in body weight after the peanut interventions (MD: 0.97; 95% CI, 0.54 to 1.41; p < 0.0001), although not in body fat or body mass index. According to the dose-response analyses, body weight increased slightly with higher doses of peanuts. In conclusion, a regular consumption of peanuts seems to modulate lipid metabolism, reducing triglyceride blood levels.

Plain language summary
Metabolic syndrome is a condition characterised by at least three of the five risk factors, such as abdominal obesity, elevated fasting glucose, blood pressure and triglycerides and reduced high-density lipoprotein cholesterol (HDL-c). There is a strong link between metabolic syndrome and the development of cardiovascular disease and Type 2 diabetes. Research suggests that increasing consumption of flavonoid-rich foods can be beneficial in reducing cardiovascular morbidity and mortality. Flavonoids are bioactive compounds that possess antioxidative, anti-inflammatory, anti-cancerous, anti-mutagenic, and enzymatic properties. This systematic review of 29 randomised controlled trials evaluated the beneficial effects of long-term flavonoid supplementation in reducing the risk factors of metabolic syndrome. This review included a variety of flavonoid supplements, such as anthocyanin, hesperidin, quercetin, epigallocatechin gallate (egcg), genistein, theaflavin, catechin, and eriocitrin. Additionally, this research investigated the mechanisms behind the beneficial effects of flavonoid supplementation. Results showed that flavonoid supplementation for at least three weeks improved metabolic parameters and inflammatory markers, with hesperidin showing the greatest improvements in metabolic parameters. Healthcare professionals can use these findings to understand the potential benefits of long-term flavonoid supplementation in improving metabolic parameters. However, more robust studies are needed to determine the therapeutic dosages of different flavonoids.
Abstract
Diets high in bioactive compounds, such as polyphenols, have been used to mitigate metabolic syndrome (MetS). Polyphenols are a large group of naturally occurring bioactive compounds, classified into two main classes: non-flavonoids and flavonoids. Flavonoids are distributed in foods, such as fruits, vegetables, tea, red wine, and cocoa. Studies have already demonstrated the benefits of flavonoids on the cardiovascular and nervous systems, as well as cancer cells. The present review summarizes the results of clinical studies that evaluated the effects of flavonoids on the components of the MetS and associated complications when offered as supplements over the long term. The results show that flavonoids can significantly modulate several metabolic parameters, such as lipid profile, blood pressure, and blood glucose. Only theaflavin and catechin were unable to affect metabolic parameters. Moreover, only body weight and body mass index were unaltered. Thus, the evidence presented in this systematic review offers bases in support of a flavonoid supplementation, held for at least 3 weeks, as a strategy to improve several metabolic parameters and, consequently, reduce the risk of diseases associated with MetS. This fact becomes stronger due to the rare side effects reported with flavonoids.

Plain language summary
Metabolic syndrome (MetS) is a cluster of metabolic disorders such as hyperlipidaemia, hypertension, hyperglycaemia, insulin resistance, and abdominal obesity. MetS is associated with cardiovascular disease (CVD), type 2 diabetes mellitus and non-alcoholic fatty liver disease. The aim of this study was to investigate the effects of curcumin and/or coenzyme Q10 supplementation on metabolic syndrome components in subjects with MetS. This study is a 2×2 factorial, randomised, double-blinded, placebo-controlled study which was conducted for 12 weeks. Eighty-eight subjects were randomly assigned into four groups. All subjects completed the trial. Results show that curcumin supplementation improves lipid profile, but it does not have any effect on body composition, hypertension and fasting plasma glucose. However, supplementation with coenzyme Q10 as well as curcumin plus coenzyme Q10 did not show any significant effects on lipid profile, body composition, hypertension and fasting plasma glucose. Authors conclude that curcumin supplementation (especially by its effects on dyslipidaemia) is more effective than coenzyme Q10 as well as the combination of curcumin and coenzyme Q10 in the management of MetS. However, curcumin, coenzyme Q10 and their combination have no effect on body composition, hypertension and glycaemic control.
Abstract
BACKGROUND Metabolic syndrome (MetS) as a cluster of conditions including hyperlipidemia, hypertension, hyperglycemia, insulin resistance, and abdominal obesity is linked to cardiovascular diseases and type 2 diabetes. Evidence suggested that intake of curcumin and coenzyme Q10 may have therapeutic effects in the management of MetS. AIMS We investigated the effects of curcumin and/or coenzyme Q10 supplementation on metabolic syndrome components including systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference (WC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-c) and fasting plasma glucose (FPG) as primary outcomes, and total cholesterol (TC), low density lipoprotein-cholesterol (LDL-c) and body mass index (BMI) as secondary outcomes in subjects with MetS. METHODS In this 2 × 2 factorial, randomized, double-blinded, placebo-controlled study, 88 subjects with MetS were randomly assigned into four groups including curcumin plus placebo (CP), or coenzyme Q10 plus placebo (QP), or curcumin plus coenzyme Q10 (CQ), or double placebo (DP) for 12 weeks. RESULTS The CP group compared with the three other groups showed a significant reduction in HDL-c (P = 0.001), TG (P < 0.001), TC (P < 0.001), and LDL-c (P < 0.001). No significant differences were seen between the four groups in terms of SBP, DBP, FPG, WC, BMI and weight. CONCLUSION Curcumin improved dyslipidemia, but had no effect on body composition, hypertension and glycemic control. Furthermore, coenzyme Q10 as well as the combination of curcumin and coenzyme Q10 showed no therapeutic effects in subjects with MetS. The trial was registered on 09/21/2018 at the Iranian clinical trials website (IRCT20180201038585N2), URL: https://www.irct.ir/trial/32518 .

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is characterised by fat deposition that is not linked to excessive alcohol intake. This condition is often linked to other health issues such as obesity, metabolic syndrome, type 2 diabetes and cardiovascular disease, and they share common diagnostic biomarkers. An unhealthy diet and lifestyle are also linked to the progression of NAFLD. Mediterranean diet is a predominantly plant-based diet that may have an association with lower risk and reduced severity of NAFLD. This multicentre, prospective, randomised controlled trial included one hundred and thirty-six NAFLD patients to analyse the effect of Mediterranean diet adherence on NAFLD in patients with metabolic syndrome. The NAFLD patients followed a personalised Mediterranean diet and physical activity interventions for six months. Individuals with greater adherence to the Mediterranean diet and physical activity interventions showed improvements in body mass index, body weight, waist circumference, blood pressure and intrahepatic fat content after six months of intervention. Healthcare professionals can use the results of this study to understand the benefits of adherence to the Mediterranean diet and physical activity interventions in reducing NAFLD severity and metabolic irregularities. However, due to the small sample size of this study, further robust studies are required to evaluate the benefits of different dietary strategies, the therapeutic value of different food items and the intervention duration required to achieve improvements in NAFLD and metabolic syndrome.
Abstract
Unhealthy diet is an important factor in the progression of non-alcoholic fatty liver disease (NAFLD). Previous studies showed the benefits of a Mediterranean diet (MedDiet) on Metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM), and cardiovascular diseases, which usually have a pathophysiological relationship with NAFLD. To assess the effect of adherence to a MedDiet on NAFLD in MetS patients after lifestyle intervention, this multicentre (Mallorca and Navarra, Spain) prospective randomized trial, with personalized nutritional intervention based on a customized MedDiet, coupled with physical activity promotion was performed to prevent, and reverse NAFLD among patients with MetS. The current analysis included 138 patients aged 40 to 60 years old, Body Mass Index (BMI) 27-40 kg/m2, diagnosed with NAFLD using MRI, and MetS according to the International Diabetes Federation (IDF). A validated food frequency questionnaire was used to assess dietary intake. Adherence to Mediterranean diet by means of a 17-item validated questionnaire, anthropometrics, physical activity, blood pressure, blood biochemical parameters, and intrahepatic fat contents (IFC) were measured. The independent variable used was changes in MedDiet adherence, categorized in tertiles after 6 months follow-up. Subjects with high adherence to the MedDiet showed higher decreases in BMI, body weight, WC, SBP, DBP, and IFC. An association between improvement in adherence to the MedDiet and amelioration of IFC after 6-month follow-up was observed. High adherence to the MedDiet is associated with better status of MetS features, and better values of IFC.

Plain language summary
With Type 2 Diabetes growing globally this paper analyses whether T2D is preventable with lifestyle measures including diet. Seven RCTs were included for review with a total of 4090 participants, and 2466 incidents of T2D, and were chosen on the basis that the lifestyle interventions included both physical exercise and diet (typically Mediterranean Diet). They found that diet and lifestyle intervention reduced the risk of T2D by 47%. Sustained risk reduction was also found in follow-up studies up to 10 years later with participants maintaining improved blood glucose control. Lifestyle interventions may also reduce risk factors for cardiovascular disease. Weight reduction was considered a cornerstone of preventing T2D and adherence to lifestyle changes a key element in long term prevention. Dietary foods reviewed include processed meats, white rice and sugars which correlated highly with T2D whilst leafy greens, berries, wholegrains, legumes, dietary fibre and yoghurt correlate with a lower risk of T2D. Dietary patterns of skipping breakfast and snacking correlate higher with T2D. Different criteria for evaluating physical activity estimate that it reduces risk factors by 50%. In conclusion there is high evidence that lifestyle factors which optimise diet, increase physical activity and promote weight reduction are preventative factors for T2D and can be sustained long term.
Abstract
Prevention of type 2 diabetes (T2D) is a great challenge worldwide. The aim of this evidence synthesis was to summarize the available evidence in order to update the European Association for the Study of Diabetes (EASD) clinical practice guidelines for nutrition therapy. We conducted a systematic review and, where appropriate, meta-analyses of randomized controlled trials (RCTs) carried out in people with impaired glucose tolerance (IGT) (six studies) or dysmetabolism (one study) to answer the following questions: What is the evidence that T2D is preventable by lifestyle changes? What is the optimal diet (with a particular focus on diet quality) for prevention, and does the prevention of T2D result in a lower risk of late complications of T2D? The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was applied to assess the certainty of the trial evidence. Altogether seven RCTs (N = 4090) fulfilled the eligibility criteria and were included in the meta-analysis. The diagnosis of incident diabetes was based on an oral glucose tolerance test (OGTT). The overall risk reduction of T2D by the lifestyle interventions was 0.53 (95% CI 0.41; 0.67). Most of the trials aimed to reduce weight, increase physical activity, and apply a diet relatively low in saturated fat and high in fiber. The PREDIMED trial that did not meet eligibility criteria for inclusion in the meta-analysis was used in the final assessment of diet quality. We conclude that T2D is preventable by changing lifestyle and the risk reduction is sustained for many years after the active intervention (high certainty of evidence). Healthy dietary changes based on the current recommendations and the Mediterranean dietary pattern can be recommended for the long-term prevention of diabetes. There is limited or insufficient data to show that prevention of T2D by lifestyle changes results in a lower risk of cardiovascular and microvascular complications.

Children and adolescents with obesity are at a high risk of being obese in adulthood. The aim of this study was to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity. The study is based on the Intervention for Childhood and Adolescents Obesity via Activity and Nutrition (ICAAN) – quasi-experimental intervention trial - which recruited 103 participants aged between 6 and sixteen years (63 were boys and 40 girls). The study was based on 2 active treatment groups (usual care group vs exercise group) receiving a 16-week intervention program. Results indicate that children and adolescents with obesity can achieve positive effects on body composition, physical fitness, and cardiometabolic markers, particularly with the exercise intervention. Authors conclude that the moderate-intensity multidisciplinary lifestyle intervention program they developed, can be sustained in the real-world setting and it is applicable to both moderate and severe obesity.
Abstract
This study aimed to develop a multidisciplinary lifestyle intervention program targeted at children and adolescents with moderate to severe obesity, and assess the additional effects of exercise intervention when compared to usual care. Overall, the 103 enrolled participants were ≥85th percentile of age and sex-specific body mass index (BMI). Participants were divided into groups that received 16 weeks of either usual care or exercise intervention. The BMI z-score of the overall completers decreased by about 0.05 after the 16-week intervention (p = 0.02). After the intervention, only the exercise group had a significantly lower BMI z-score than the baseline score by about 0.1 (p = 0.03), but no significant group by time interaction effects were observed. At the 16-week follow-up, significant group by time interaction effects were observed in percentage body fat (%BF) (β = -1.52, 95%CI = -2.58⁻-0.45), lean body mass (LM) (β = 1.20, 95%CI = 0.12⁻2.29), diastolic blood pressure (β = -5.24, 95%CI = -9.66⁻-0.83), high-sensitivity C-reactive protein (β = -1.67, 95%CI = -2.77⁻-1.01), and wall sit test score (β = 50.74, 95%CI = 32.30⁻69.18). We developed a moderate-intensity intervention program that can be sustained in the real-world setting and is practically applicable to both moderate and severe obesity. After interventions, the exercise group had lower %BF and cardiometabolic risk markers, and higher LM and leg muscle strength compared to the usual care group.

Selenium (Se) is an antioxidative micronutrient that activates Se-containing proteins known as selenoproteins. The aim of this study was to examine the relationship between serum Se level and metabolic syndrome including each metabolic factor. A secondary aim was to find a correlation between obesity, insulin resistance, and gender. The study is a case control study based on the comparison of Se levels between patients with and without metabolic syndrome. The study enrolled a total of 1165 ambulatory males or females, aged more than 40 years. Results showed a positive association between serum Se level and the risk of metabolic syndrome. Also, the serum Se concentration was positively associated with a number of metabolic factors following a dose–response relationship. Authors conclude that gender stratification analyses clearly highlighted the gender differences in insulin resistance, adiposity, and lipid metabolism.
Abstract
Few studies have investigated the association between selenium and metabolic syndrome. This study aimed to explore the associations between the serum selenium level and metabolic syndrome as well as examining each metabolic factor. In this case-control study, the participants were 1165 adults aged ≥40 (65.8 ± 10.0) years. Serum selenium was measured by inductively coupled plasma-mass spectrometry. The associations between serum selenium and metabolic syndrome were examined by multivariate logistic regression analyses. The least square means were computed by general linear models to compare the serum selenium levels in relation to the number of metabolic factors. The mean serum selenium concentration was 96.34 ± 25.90 μg/L, and it was positively correlated with waist circumference, systolic blood pressure, triglycerides, fasting glucose, and homeostatic model assessment insulin resistance (HOMA-IR) in women, but it was only correlated with fasting glucose and HOMA-IR in men. After adjustment, the odds ratios (ORs) of having metabolic syndrome increased with the selenium quartile groups (p for trend: <0.05), especially in women. The study demonstrated that the serum selenium levels were positively associated with metabolic syndrome following a non-linear dose⁻response trend. Selenium concentration was positively associated with insulin resistance in men and women, but it was associated with adiposity and lipid metabolism in women. The mechanism behind this warrants further confirmation.

Physical activity has been shown to considerably reduce the burden of several non-communicable disorders (are diseases of long duration and generally slow progression), such as heart disease, stroke, diabetes, and breast and colon cancers. The aim of the study is to estimate the prevalence of physical activity among a mixed group of patients with psychiatric illnesses in Saudi Arabia. Furthermore, the study sought to evaluate the associations between physical activity, patients with different psychiatric diagnoses and the use of psychotropic medications. The study is a cross-sectional observational study that recruited 1185 patients seeking psychiatric advice, with an average age of 38.0±13.0 years. Results indicate a low prevalence of physical activity in a large, mixed sample of patients with psychiatric illnesses in both inpatient and outpatient settings in Saudi Arabia. Authors conclude that physical activity levels vary according to the type of psychiatric disease and the medications used. They outline that it is important to assess the physical activity status in patients with psychiatric illnesses and promote physical activity programs among psychiatric patients.
Abstract
OBJECTIVES To estimate prevalence of physical activity and its associations with various psychiatric disorders and the use of psychotropic medications. METHODS A cross-sectional observational study was carried out between July 2012 and June 2014. Patients were enrolled from a number of hospitals located in 5 regions of the Kingdom of Saudi Arabia. RESULTS A total of 1185 patients were included in current analysis: 796 were outpatients, and 389 were inpatients. Out of 1,185 patients, 153 (12.9%) were physically active. Much higher rates of physical activity were reported among males than females (15.9% versus 9.6%, p less than 0.001). According to the univariate analysis, higher rates of physical activity were positively correlated with primary bipolar disorders, the use of antianxiety medications and, to a lesser extent, use of antipsychotic medications, but they were negatively correlated with primary anxiety disorders, use of antidepressant medications, and use of multiple psychotropic medications. The associations between physical activity and primary bipolar disorders (odds ratio [OR]=2.47, p=0.002), use of antianxiety medications (OR=3.58, p=0.003), and use of multiple psychotropic medications (OR=0.33, p less than 0.001) remained significant after adjusting for demographic and clinical characteristics. CONCLUSION We report a variable but generally low prevalence of physical activity among a large, mixed sample of psychiatric patients in Saudi Arabia. These findings may highlight the importance of assessing physical activity status of psychiatric patients and the critical need for physical activity promotion programs among this group of disadvantaged patients.

Plain language summary
Metabolic Syndrome is the term used to group a cluster of health concerns including overweight, obesity, hypertension, elevated cholesterol, blood glucose intolerance and insulin resistance which together can contribute to the development of Type II Diabetes and Cardiovascular Disease. Diagnosis is usually given if a patient has three or more of these conditions however the diagnosis in children and adolescents is often inconsistent, and so guidelines for therapeutic strategies for metabolic syndrome also vary greatly. This review looked at 9 studies of children aged up to 19 years old, all diagnosed with metabolic syndrome, and given dietary, physical, psychological, and pharmacological interventions, to try and understand what the best clinical approach might be. It was found that a balanced diet combined with aerobic and resistance exercise helped to significantly reduce body mass, more so than the trials which included treatment with Metformin. A balance diet included calorie restriction and carbohydrate reduction, carefully planned around the daily exercise program of 2-3 resistance sessions each week and frequent cardio sessions of differing intensity and duration. They concluded that a minimum of 6 months was needed to reach optimal weight loss and body fat loss. Overall, the findings of this study support diet and physical exercise as beneficial clinical interventions, whilst the use of medication is still unclear.
Abstract
OBJECTIVE To record which interventions produce the greatest variations in body composition in patients ≤19 years old with metabolic syndrome (MS). METHOD search dates between 2005 and 2017 in peer reviewed journals, following the PRISMA method (Preferred Reporting Items for Systematic reviews and Meta-Analyses). The selection criteria were: diagnostic for MS or at least a criterion for diagnosis; randomized clinical trials, ≤19 years of age; intervention programs that use diet and/or exercise as a tool (interventions showing an interest in body composition). RESULTS 1781 clinical trials were identified under these criteria but only 0.51% were included. The most frequent characteristics of the selected clinical trials were that they used multidisciplinary interventions and were carried out in America. The most utilized parameters were BMI (body mass index) in kg/m² and BW (body weight) in kg. CONCLUSIONS Most of the clinical trials included had been diagnosed through at least 2 diagnostic criteria for MS. Multidisciplinary interventions obtained greater changes in body composition in patients with MS. This change was especially prevalent in the combinations of dietary interventions and physical exercise. It is proposed to follow the guidelines proposed for patients who are overweight, obese, or have diabetes type 2, and extrapolate these strategies as recommendations for future clinical trials designed for patients with MS.

There is conflicting evidence on the benefits of either skipping breakfast versus the idea that breakfast is the most important meal of the day. This study examines the effects of skipping breakfast on weight loss in a group of 240 participants diagnosed as having Metabolic syndrome (MetS). The study looked at data from a diet trial looking at the effects of a high fibre diet or the American Heart Association diet on MetS, in which they all also monitored breakfast eating patterns, to see if there was any change to body weight, nutrient intakes, and selected metabolic measures. The study lasted one year, and dietary recalls were collected throughout. The results showed that at the start of the trial 32.9% of the participants self-reported regularly skipped breakfast and generally they had lower levels of vitamins B1, B3 and folate intake. They also had a higher fat intake compared to those who ate breakfast. However, at the end of the year there was no statistical differences between those who ate and those who skipped breakfast when it came to the other metabolic parameters of weight, BMI, weight circumference, blood pressure, cholesterol, and fasting glucose. Interestingly at the end of the trial only 14% reported skipping breakfast suggesting that participants had the intention to change their eating patterns because of having participated in the trial. The study concluded that skipping breakfast alone was not enough to influence MetS.
Abstract
The effect of skipping breakfast on health, especially in adults, remains a controversial topic. A secondary data analysis was conducted to examine associations between breakfast eating patterns and weight loss, nutrient intake, and metabolic parameters among participants with metabolic syndrome (MetS) (n = 240). Three randomly selected 24-h dietary recalls were collected from each participant at baseline and at the one-year visit. Skipped breakfast was seen in 32.9% at baseline and in 17.4% at the one-year visit, respectively. At baseline, after adjustment for demographics and physical activity, participants who ate breakfast had a higher thiamin, niacin, and folate intake than did breakfast skippers (p < 0.05); other selected parameters including body weight, dietary quality scores, nutrient intake, and metabolic parameters showed no significant differences between the two groups (p ≥ 0.05). From baseline to one year, after adjustment for covariates, mean fat intake increased by 2.7% (95% confidence intervals (CI): -1.0, 6.5%) of total energy in breakfast skippers in comparison to the 1.2% decrease observed in breakfast eaters (95% CI: -3.4, 1.1%) (p = 0.02). Mean changes in other selected parameters showed no significant differences between breakfast skippers and eaters (p > 0.05). This study did not support the hypothesis that skipping breakfast has impact on body weight, nutrient intakes, and selected metabolic measures in participants with MetS.
