Prevalence of metabolic syndrome in Brazilian adults: a systematic review

Sociodemographic and reproductive risk factors associated with metabolic syndrome in a population of Brazilian women from the city of Ribeirão Preto: a cross-sectional study

Objective

To identify sociodemographic and reproductive risk factors associated with MetS in women in their fourth decade of life.

Methods

Cohort study conducted on women born from June 1978 to May 1979 in Ribeirão Preto, Brazil. Sociodemographic, clinical, and obstetric data were collected by interview and clinical evaluation. Univariable and multivariable binomial logistic regression models were constructed to identify the risk factors of metabolic syndrome and the adjusted relative risk (RR) was calculated.

Results

The cohort included 916 women, and 286 (31.2%) of them have metabolic syndrome. MetS was associated with lack of paid work (RR 1.49; 95% CI 1.14-1.95), marital status of without a partner (RR 1.33; 95% CI 1.03-1.72), low educational level (less than 8 years of schooling [RR 1.72; 95% CI 1.23-2.41], 8 to 12 years of schooling [RR 1.37; 95% CI 1.06-1.76], when compared with more than 12 years of schooling), and teenage pregnancy (RR 2.00; 95% CI 1.45-2.77). There was no association between MetS, and the other covariates studied.

Conclusion

Metabolic syndrome in a population of women in the fourth decade of life was associated with lack of employment, lack of a partner, low educational level, and teenage pregnancy.

2024 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Transitioning from having no metabolic abnormality nor obesity to metabolic impairment in a cohort of apparently healthy adults

INTRODUCTION

The global prevalence of metabolic syndrome and its association with increased morbidity and mortality has been rigorously studied. However, the true prevalence of "metabolic health", i.e. individuals without any metabolic abnormalities is not clear. Here, we sought to determine the prevalence of "metabolically healthy" individuals and characterize the "transition phase" from metabolic health to development of dysfunction over a follow-up period of 5 years.

METHODS

We included 20,507 individuals from the Tel Aviv Sourasky Medical Center Inflammation Survey (TAMCIS) which comprises apparently healthy individuals attending their annual health survey. A second follow-up visit was documented after 4.8 (± 0.6) years. We defined a group of metabolically healthy participants without metabolic abnormalities nor obesity and compared their characteristics and change in biomarkers over time to participants who developed metabolic impairment on their follow-up visit. The intersections of all metabolic syndrome components and elevated high sensitivity C-reactive protein (hs-CRP) were also analyzed.

RESULTS

A quarter of the cohort (5379 individuals, (26.2%) did not fulfill any metabolic syndrome criteria during their baseline visit. A total of 985 individuals (12.7% of returning participants) developed metabolic criteria over time with hypertension being the most prevalent component to develop among these participants. Individuals that became metabolically impaired over time demonstrated increased overlap between metabolic syndrome criteria and elevated hs-CRP levels. The group that became metabolically impaired over time also presented higher delta values of WBC, RBC, liver biomarkers, and uric acid compared with participants who were consistently metabolically impaired. LDL-C (low-density lipoprotein cholesterol) delta levels were similar.

CONCLUSIONS

Roughly one-quarter of apparently healthy adults are defined as "metabolically healthy" according to current definitions. The transition from health to metabolic dysfunction is accompanied with active inflammation and several non-metabolic syndrome biomarkers. Aggressive screening for these biomarkers, blood pressure and hs-CRP might help identify apparently healthy individuals at increased risk of developing metabolic syndrome over time.

Effect of liraglutide on cardiometabolic profile and on bioelectrical impedance analysis in patients with obesity and metabolic syndrome

Metabolic syndrome (MetS) and obesity represent a public health problem worldwide. Bioelectrical impedance analysis (BIA) is a practical and effective way of evaluating body composition, especially abdominal fat. Liraglutide, a GLP-1 analog, reduces body weight and improves cardiometabolic parameters. In this prospective non-randomized intervention study, we evaluated the effect of 6 months of treatment with liraglutide (n = 57) on the clinical, laboratory and BIA findings of adult sex-stratified patients diagnosed with obesity and MetS, compared to a control group receiving sibutramine (n = 46). The groups were statistically similar with regard to the age of females (p = 0.852) and males (p = 0.657). Almost all anthropometric and BIA variables were higher in the treatment group than in the comparative group (p < 0.05). Abdominal circumference (AC) decreased significantly more in the treatment group. In males, body weight and fat mass also decreased (p < 0.05). Liraglutide treatment was associated with a greater reduction in trunk fat mass (FMT) (p < 0.05). AC and FMT were strongly correlated (rho = 0.531, p < 0.001) in the treatment group. In the multiple regression analysis, liraglutide treatment remained independently associated with FMT. Treatment with liraglutide for 6 months promoted weight loss, improved cardiometabolic and inflammatory parameters and led to a significant reduction in FMT correlated with AC in obese MetS patients of both sexes.

24 h movement behavior and metabolic syndrome study protocol: A prospective cohort study on lifestyle and risk of developing metabolic syndrome in undergraduate students from low-income regions during a pandemic

Introduction

Obesity and its comorbidities are increasingly prevalent in Latin America, with a more rapid growth in individuals with lower income. The composition of movement behaviors within a 24 h period may have important implications for obesity, metabolic and mental health in cross-sectional data. However, a longitudinal study is needed to confirm the findings from the primarily cross-sectional evidence. The COVID-19 pandemic has been associated with cardiometabolic outcomes and has impeded healthy behavior.

Objectives

The first objective is to evaluate the time elapsed since the diagnosis of not meeting 24 h movement guidelines and the potential subsequent onset of metabolic syndrome in undergraduate students from low-income regions within 4 years of follow up. The second objective is to test the association between 24 h movement, mental wellbeing, eating behaviors, and abdominal obesity in the period of this pandemic.

Methods

The 24 h movement behavior and metabolic syndrome (24 h-MESYN) study is a multicentre cohort study that will include participants from two Brazilian cities within the 2022-2025 period to asses the first objective, and also a nested case-control study at the baseline will be carried out to evaluate the second objective. Previously, we conducted a feasibility study in the academic year of 2021 to assessing the psychometric properties of subjective tools, refine our study protocol, and adjust the epidemiological conditions of the cohort's subsequent phases (like as prevalence of exposure of interest, sampling process, and study adherence). Statistical tests as Cohen's kappa agreement; factorial analysis; logistic, Poisson and linear regression; and Kaplan-Meier analysis will be performed, in accordance with the objectives.

Prevalence and Factors Associated with Metabolic Syndrome in Patients at a Psychosocial Care Center: A Cross-Sectional Study

BACKGROUND

Metabolic syndrome (MS) is associated with greater risk of morbimortality and it has high prevalence in people with mental illness.

OBJECTIVE

Estimate the prevalence of Metabolic Syndrome (MS) and its associated factors in the patients of a Psychosocial Care Center (CAPS in Brazilian Portuguese) in the city of Salvador, state of Bahia, Brazil.

METHOD

Cross-sectional study set at CAPS in the city of Salvador-Bahia between August 2019 and February 2020. MS was evaluated according to the National Cholesterol Education Program's Adult Treatment Panel III. In addition to descriptive statistics, gross and adjusted prevalence ratios were described.

RESULTS

MS was found in 100 (35.2%) individuals, 116 (40.9%) were obese and 165 (58.1%) had increased waist circumference. Polypharmacy was identified in 63 (22.3%) patients and 243 (85.9%) used antipsychotics. Under gross evaluation, women (PR = 1.88; 95%CI: 1.35-2.63) and those who used antidepressants (PR = 1.41; 95%CI: 1.05-1.88) showed an association with MS. After logistic regression, depression (PR = 1.86; 95%CI: 1.38-2.51), acanthosis (PR = 1.50; 95%CI: 1.18-1.90), use of antipsychotics (PR = 1.88; 95%CI: 1.13-2.75), and hypertriglyceridemic waist (PR = 3.33; 95%CI: 2.48-4.46) were associated with MS.

CONCLUSION

The prevalence of MS signals multimorbidity among individuals with mental disorders and suggests a need for clinical screening.

Epidemiology of metabolic syndrome in Tunisia. HSHS 5 study

OBJECTIVE

To measure the prevalence of metabolic syndrome and its components in the HSHS cohort (Hammam Sousse, Tunisia), in 2009, and to identify its determining factors.

METHODS

This was a descriptive epidemiological study of the "community based" type having focused on a random sample of people aged 20 and over. The metabolic syndrome was defined according to the criteria of the "International Diabetes Federation" (IDF 2005) and those of the "National Cholesterol Education Program-Adult Treatment Panel III" (NCEP-ATP III, 2001).

RESULTS

The study involved 1441 people including 960 women (66.6%). The age- and sex-adjusted prevalences of increased waist circumference, blood pressure, blood sugar and triglycerides, and decreased HDL-cholesterol were respectively 63.2%, 95%CI[62.5-63.8]; 47.7%, 95%CI[47.4-48.6]; 25.7%, 95%CI[25.1-26.2]; 11.9%, 95%CI[11.4-12.3] and 65,6%, 95%CI[65.0-66.2], according to IDF thresholds and 37.4%, 95%CI[36.3-37.6]; 45.7%, 95%CI[45.4-46.6]; 13.8%, 95%CI[13.4-14.2]; 8.4%, 95%CI[8.0-8.7] and 61.9%, 95%CI[61.2-62.5], according to those of the NCEP-ATP III. The prevalence of metabolic syndrome adjusted for age and sex was 36.5% 95%CI[33.0%-38.9%] according to the IDF definition and 23.0% 95%CI[20.4%-25.6%] according to that of NCEP-ATP III. The multivariate study by logistic regression made it possible to retain three significant independent determining factors of the metabolic syndrome: age ≥40 years, low level of physical activity and family history of diabetes mellitus with respectively adjusted ORs of 3.77 95%CI[2.70-5.27], 1.39 95%CI[1.01-1.89], 1.62 95%CI[1.21-2.15], according to IDF and 5.87 95%CI[3.88 -8.88], 1.47 95%CI[1.07-2.01] and 1.45 95%CI[1.07-1.96], according to NCEP-ATP III .

CONCLUSION

With this high prevalence rate of the metabolic syndrome, the establishment of an action plan would be essential. This plan should be based on the combination of the promotion of physical activity and screening for the components of the metabolic syndrome, particularly in subjects aged 40 or over, with a family history of diabetes mellitus.

Global prevalence of metabolic syndrome in patients with psoriasis in the past two decades: current evidence

Patients with psoriasis are at an increased risk of metabolic syndrome (MetS); however, a systematic analysis of its global prevalence has not been performed to date. Here, we performed a systematic review and meta-analysis to assess the prevalence of MetS among patients with psoriasis. We searched five databases from inception through September 2021 and used the Agency for Healthcare Research and Quality (AHRQ) and Newcastle-Ottawa Scale (NOS) tools to assess observational study quality. Stata SE 15.1 was used to perform the data analysis. Subgroup, meta-regression and sensitivity analyses were used to evaluate interstudy heterogeneity. Publication bias was evaluated using Egger's and Begg's linear tests. The global prevalence of MetS in patients with psoriasis was 32% (95% confidence interval [CI], 0.26-0.38). The prevalence in adults was 32% (95% CI, 0.29-0.36), while that in children and adolescents was 9% (95% CI, 0.00-0.18). Latin America had the highest prevalence of 47% (95% CI, 0.43-0.51), whereas North America had the lowest prevalence of 26% (95% CI, 0.16-0.37). Patients with psoriasis vulgaris (29%; 95% CI, 0.23-0.35) or severe psoriasis (37%; 95% CI, 0.27-0.46) had a higher prevalence of MetS than those with other psoriasis types. These findings suggest that MetS should be appropriately recognized and managed in patients with psoriasis. More population-based prospective observational studies are required to elucidate the mechanisms underlying the coexistence of MetS in patients with psoriasis.

Overview of Nutraceuticals and Cardiometabolic Diseases following Socio-Economic Analysis

The importance of functional food and nutraceutical products to deal with cardiometabolic diseases (CMDs) and metabolic syndrome (MetS) has gained attention in the past few years. The aim of this narrative review is to highlight the potential and effectiveness of nutraceutical in the improvement of CMDs and MetS biomarkers, alongside their burden of disease and economic health expenditure. A science database search was conducted between May and June 2021. A total of 35 studies were included in this paper. We included male and female subjects, children, and adults, in good health or with cardiovascular or metabolic disease. CMDs and MetS have gradually become worldwide health problems, becoming two of the major causes of morbidity and mortality in western countries. The results indicate a positive link between daily consumption of nutraceutical products and an improvement in cardiometabolic and anthropometric biomarkers. In this paper we included a wide range of nutraceutical products. Most of them showed promising data, indicating that nutraceuticals could provide a new therapeutic treatment to reduce prevalence and pharmaceutical expenditures attributed to CMDs and MetS. Unfortunately, there is a huge vacuum of data on nutraceutical usage, savings, and burden reduction. Therefore, further clinical and pharmaco-economic research in the field is highly required.

The Racial Disparities in the Epidemic of Metabolic Syndrome With Increased Age: A Study From 28,049 Chinese and American Adults

BACKGROUND

Previous studies have revealed ethnic disparities in the prevalence of metabolic syndrome (MetS); however, the literature regarding aging-related patterns of disparities in MetS and its components remains limited.

METHODS

This cross-sectional study recruited 28,049 subjects, consisting of one Chinese race and three American races, 18-85 years of age, from the National Health and Nutrition Examination Survey (NHANES, 1999-2018) of the United States, and the Guangdong Gut Microbiome Project (GGMP, 2018) of China. MetS was defined in accordance with the National Cholesterol Education Program Adult Treatment Panel III. A modified sliding-window-based algorithm was used to depict the trajectories of the prevalence of MetS with increased age. Logistic regression analysis was performed to investigate associations between MetS and its components.

RESULTS

The prevalence of MetS increased non-linearly with age, with growth speed reaching its maximum at approximately 40-50 years. Chinese subjects exhibited a lower prevalence of MetS than non-Hispanic whites, non-Hispanic blacks, and Mexican Americans in all age groups. The two most prevalent components in Chinese subjects were reduced high-density lipoprotein cholesterol levels (42.0%) and elevated blood pressure (49.5%), and elevated triglyceride levels (36.3-49.5%) and abdominal obesity (55.8-55.9%) in Americans. Before 40 years of age, the top two MetS-associated components were abdominal obesity and elevated triglyceride levels in all races, while after 40 years, the prominent associations between MetS and its components varied among the different races and age groups.

CONCLUSIONS

Although racial disparities in the epidemic of MetS varied with increased age, abdominal obesity and elevated triglyceride levels were the top two MetS-associated components in all younger adults of different races.

Prevalence of metabolic syndrome in Brazilian adults in the last 10 years: a systematic review and meta-analysis

Background

A cluster of interconnected cardiometabolic risk factors characterizes metabolic Syndrome (MS). The prevalence of MS is increasing worldwide, but there is not a meta-analysis of this prevalence in the Brazilian population. We aimed to determine the prevalence of metabolic syndrome among adult general population in Brazil through a meta‑analysis study.

Methods

Original research studies were searched at PubMed, Scopus, Web of Science, and SciELO databases, from 2011 to 2021. We used the Joanna Briggs Institute tool to assess the quality of included studies. The random effect model was used to estimate the pooled prevalence of MS. Subgroup and meta-regression analysis were conducted for explored heterogeneity and used the Funnel Plot and Egger’s test to assess publication bias. The study was performed based on the criteria of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).

Results

The search in electronic databases identified 1598 records. From this total, 26 studies were eligible to be included in the final analysis. The overall pooled prevalence among the general population of Brazil was 33% with high heterogeneity observed. By gender, the prevalences were 26% in males and 38% in females. By criteria that was used to define MS, the prevalence were 31% in NCEP ATP III, 25% in JIS, 37% in IDF/NHLBI/AHA/WHF/IAS/IASO and 33% in IDF criteria. The prevalence in different habitat was 34% in urban, 15% in rural, 28% in quilombola and 37% in indigenous. In different regions was 37% in the South, 30% in Southeast, 38% in North, 31% in Northeast and 39% in Midwest. The pooled prevalence of MS with age was < 45 years: 43% and ≥ 45 years: 42% and the prevalence based on year of study implementation was 31% in 2015–2019, 35% in 2010–2014 and 28% in 2005–2009. There were no statistically significant differences between subgroups. Most of the studies showed high quality assessment criteria’s except adequate sample size criteria and many studies participants were not sampled in an appropriate way.

Conclusions

Our review indicates a high prevalence of MS in the healthy Brazilian adult population, when compared to others countries and with a world estimate.

Predictors of Health Promotion Behaviors Among Working Adults at Risk for Metabolic Syndrome

BACKGROUND

Metabolic syndrome has a high global prevalence, affecting 26% of South Koreans. Lifestyle modifications have shown benefits in studies involving health behavior enhancement, specifically through workplace eating and exercise interventions. However, workplace interventions focusing on health behaviors have been inadequately explored.

OBJECTIVES

This study examined factors affecting health promotion behaviors of workers at high risk of metabolic syndrome by applying Theory of Planned Behavior constructs (attitude, subjective norm, perceived behavioral control, and intention).

METHODS

This correlational cross-sectional study collected survey data from 164 hotel workers in South Korea. The study applied factor analysis and structural equation modeling for the data analysis.

RESULTS

Analysis revealed five health promotion behaviors: exercise, making healthy food choices, avoiding fatty foods, eating a nutritious and balanced diet, and eating regular moderate meals. Participants were grouped as total participants, those with one risk factor and those with two risk factors. In the total group, four behaviors were influenced by perceived behavioral control: exercise, making healthy food choices, eating a nutritious and balanced diet, and eating regular moderate meals. In the one risk factor group, intention and attitude influenced the eating regular moderate meals behavior, and two other behaviors were influenced by perceived behavioral control: exercise and eating a nutritious and balanced diet; in the two risk factors group, only perceived behavioral control directly affected exercise.

DISCUSSION

Perceived behavioral control was a key predictor of health behaviors, and theory constructs partially explained behaviors. Perceived behavioral control influenced four behaviors and influenced exercise in all three groups. Also, theory constructs showed a greater effect on behaviors in the one risk factor group than in the two risk factor group, indicating that participants with one risk factor more effectively managed their behaviors on their own and with health care providers' support. Occupational health providers should conduct early assessments of workers showing metabolic syndrome risk factors to identify their particular risks, intention, and behaviors. As the number of risk factors affects behaviors and perceived behavioral control primarily influences exercise, these findings should be incorporated in metabolic syndrome interventions.

Variáveis clínicas consideradas fatores de risco para a síndrome metabólica: um estudo transversal

RESUMO Objetivo Identificar os principais fatores de risco para a síndrome metabólica e sua relação com a percepção da qualidade de vida em colônias pesqueiras brasileiras. Métodos Incluímos 77 participantes com idade > 18 anos. Síndrome metabólica e qualidade de vida foram os principais desfechos do estudo. Consideramos nível de significância < 0,05 e todos os procedimentos foram aprovados pelo comitê de ética. Resultados A maioria dos participantes é do sexo masculino, solteiros, classe econômica D-E, carga horária trabalhada de 6 a 8 horas, tempo de serviço de 1 a 5 anos e dedicados exclusivamente à pesca. Conclusão: Perímetro abdominal e pressão arterial foram os critérios mais frequentes e de maior contribuição para a síndrome metabólica. Apesar de a qualidade de vida apresentar maior escore para o domínio relações sociais, neste estudo, o domínio físico foi o único associado a outra observação, na qual observamos correlação significativa com a pressão arterial sistólica.

Clinical variables considered risk factors for the metabolic syndrome: a cross-sectional study

ABSTRACT Objective To identify the main risk factors for metabolic syndrome and its relationship with the perception of quality of life in Brazilian fishing colonies. Methods We included 77 participants aged > 18 years. Metabolic syndrome and quality of life were the main study outcomes. We considered a significance level < 0.05 and all procedures were approved by the ethics committee. Results Most participants are male, single, economic class D-E, working hours of 6 to 8 hours, length of service from 1 to 5 years, and dedicated exclusively to fishing. Conclusion Abdominal perimeter and blood pressures were the most frequent criteria and the greatest contribution to metabolic syndrome. Although quality of life had a higher score for the social relationship domain, in this study, the physical domain was the only one associated with another observation, in which we observed a significant correlation with systolic blood pressure.

Metabolic syndrome in middle-aged and older women: A cross-sectional study

Objective:

This study aims to compare the prevalence of metabolic syndrome between different age groups of middle-aged and older women and to assess whether these differences are independent of potential covariates.

Methods:

Study conducted with 510 women divided into three age groups: 45–54, 55–64 and 65–74 years. Socioeconomic, reproductive and lifestyle variables were self-reported. We defined metabolic syndrome using the National Cholesterol Education Program Adult Treatment Panel III criteria (abdominal obesity, diabetes, reduced high-density lipoprotein, elevated triglycerides, and hypertension). Logistic regression assessed the association between age groups, and metabolic syndrome was adjusted for covariates (socioeconomic variables, age at menarche and at first childbirth, parity, menopausal status, physical activity variables and smoking).

Results:

Women aged 55–64 years presented higher prevalence of all metabolic syndrome criteria than the other groups, except for abdominal obesity, which was higher in the oldest group. In the fully adjusted analysis, the 55–64 years age group continues to exhibit significantly higher odds of presenting metabolic syndrome when compared to the youngest group (45–54 years) (OR = 2.257; 95% CI = 1.20:4.24). There was no statistical difference in the odds of presenting metabolic syndrome when comparing the oldest and the youngest groups (OR = 1.500; 95% CI = 0.85:2.65).

Conclusion:

The higher prevalence of metabolic syndrome among those aged 55–64 years may indicate that middle-aged women become unhealthy earlier in the life course and that many of them may die prematurely. This result highlights the importance of screening metabolic syndrome earlier in the midlife and the need for public health policies aimed at reducing adverse effects in later years.

Correlation between parity and metabolic syndrome in Chinese women aged 40 years and older: the Reaction study

AIMS

The purpose of the present study was to investigate the correlation between the number of live-birth pregnancies and metabolic syndrome (MetS) in Chinese women according to menstruation history.

METHODS

Registry data for all pregnancies in a cohort of 6157 Chinese women aged 40 years or older were obtained and the number of live-birth pregnancies were enumerated. We defined MetS using five criteria: impaired insulin metabolism and glucose tolerance, obesity in the abdominal area, dyslipidemia, and hypertension. Multivariate logistic regression analysis was conducted to assess potential risk factors for MetS. Postmenopausal women with three or more of live-birth pregnancies had the highest prevalence of MetS (P < 0.05).

RESULTS

Among the 6157 females aged 40 years or older in Luzhou city, 2143 (34.8%) participants had incident MetS. The number of live-birth pregnancies was significantly correlated with age and fasting blood glucose (FBG) level (P < 0.05). The prevalence of MetS increased with the number of live-birth pregnancies (P < 0.01), and the frequency in postmenopausal women was significantly higher than that in premenopausal women (P < 0.001). In the binary logistic regression model, menopausal status [OR = 0.343 (0.153-0.769), P < 0.001] were significantly associated with an increased risk of MetS.

CONCLUSIONS

The number of live-birth pregnancies is correlated with an increased risk of MetS in Chinese women aged 40 years and over, especially in postmenopausal women. Greater attention should be paid to postmenopausal women who have had multiple live-birth pregnancies with a view to intervening early to prevent related diseases.

Cardiometabolic syndrome and associated factors among Ethiopian public servants, Addis Ababa, Ethiopia

Non-communicable diseases (NCDs) are increasingly becoming the global cause of premature death encompassing cardiovascular diseases (CVDs), cancer, respiratory diseases and diabetes mellitus. However, cardiometabolic risk factors in the general population, especially among the high-risk groups have rarely been assessed in Ethiopia. The study aimed to assess the prevalence of metabolic syndrome, its components and associated factors among staff in the Ethiopian Public Health Institute (EPHI). An institutional-based cross-section study was conducted from March to June 2018 among EPHI staff members. A total of 450 study participants were involved in the study, and the World Health Organization NCD STEPS survey instrument version 3.1 was used for the assessment. The biochemical parameters were analyzed by using COBAS 6000 analyzer. Statistical package for the social science (SPSS) version 20 was used for data analysis. Both bivariate and multivariate logistic regression analyses were used to identify associated risk factors. p value < 0.05 was considered for statistical significance. The overall prevalence of metabolic syndrome was 27.6% and 16.7% according to IDF and NCEP criteria respectively, with males having greater prevalence than females (35.8% vs 19.4%). Central obesity, low high-density lipoprotein (HDL) and hypertension had a prevalence of 80.2%, 41.3%, and 23.6%, respectively. In multivariate analysis increasing age and having a higher body mass index (25-29.9) were significantly associated with metabolic syndromes. The magnitude of metabolic syndrome was relatively high among public employees. Preventive intervention measures should be designed on the modification of lifestyle, nutrition and physical activities, and early screening for early identification of cardiometabolic risks factors should be practised to reduce the risk of developing cardiovascular diseases.

Living in the Southern Hemisphere: Metabolic Syndrome and Its Components in Amazonian Riverine Populations

The metabolic syndrome (MetS) epidemic is a global challenge. Although developing countries (including Brazil, India, and South Africa) present a higher proportion of deaths by cardiovascular diseases than developed countries, most of our knowledge is from these developed countries. Amazonian riverine populations (ARP), as well as other vulnerable populations of the Southern Hemisphere, share low-income and traditional practices, among other features. This large cross-sectional study of ARP (n = 818) shows high prevalence of hypertension (51%) and obesity (23%). MetS was diagnosed in 38% of participants (especially in women and 60-69 years-old individuals) without the influence of ancestry. Only 7-8% of adults had no cardio-metabolic abnormalities related to MetS. Atherogenic dyslipidemia (low HDL-cholesterol) was generally observed, including in individuals without MetS. Still, slight differences were detected between settings with a clear predominance of hypertension in Tucuruí. Hypotheses on possible genetic influence and factors (nutrition transition and environmental pollutants -mercury) are proposed for future studies. Moreover, a roadmap to MetS progression based on the most prevalent components is provided for the development of tailored interventions in the Amazon (initially, individuals would present low HDL-cholesterol levels, later progressing to increased blood pressure characterizing hypertension, and ultimately reaching MetS with obesity). Our alarming results support the need to improve our knowledge on these vulnerable populations.

Can Myogenic Tone Protect Endothelial Function? Integrating Myogenic Activation and Dilator Reactivity for Cerebral Resistance Arteries in Metabolic Disease

The obese Zucker rat (OZR) manifests multiple risk factors for impaired cerebrovascular function, including hypertension and insulin resistance although how they combine to produce integrated vascular function is unclear. As studies have suggested that myogenic activation (MA) severity for middle cerebral arteries (MCAs) may be proportional to hypertension severity, we hypothesized that MA will negatively correlate with dilator reactivity in OZR. MA of MCA from OZR was divided into low, medium, and high based on the slope of MA, while MCA reactivity and vascular metabolite bioavailability were assessed in all groups. Endothelium-dependent dilation of MCA in OZR was attenuated and correlated with the MA slope. Treatment of OZR MCA with TEMPOL (antioxidant) improved dilation in low or medium MA groups, but had less impact on high MA. Alternatively, treatment with gadolinium to normalize MA in OZR had reduced impact on dilator reactivity in MCA from low and medium MA groups, but improved responses in the high group. Treatment with both agents resulted in dilator responses that were comparable across all groups. These results suggest that, under conditions with stronger MA, endothelial function may receive some protection despite the environment, potentially from the ability of MCA to reduce wall tension despite increased pressure.

Cortisol level after dexamethasone suppression test in patients with non-functioning adrenal incidentaloma is positively associated with the duration of reactive hyperemia response on microvascular bed

PURPOSE

Data on endothelial derangements in patients with non-functioning adrenal incidentaloma (NFAI) are scarce.

METHODS

We investigated if NFAI patients present clinical, biochemical and endothelial alterations compared to individuals without an adrenal lesion and also the associations among these variables. Forty-two NFAI and 40 controls were evaluated. NFAI diagnosis and controls were defined according to the current guidelines and based on a normal adrenal imaging exam, respectively. Body composition was evaluated by dual emission X-ray absorptiometry. Endothelial reactivity was assessed by two methods: tonometry (Endo-PAT^®) and laser speckle contrast imaging (LSCI).

RESULTS

There were no differences between groups regarding age, gender, ethnicity, smoking status, and statin use. The frequency of metabolic syndrome according to the International Diabetes Federation criteria was 69% and 57.9%, respectively in NFAI and controls (p = 0.36), whereas the atherosclerotic cardiovascular disease (ASCVD) risk was 63.4% and 66.7% (p = 0.81). The clinical, laboratory, and anthropometric characteristics, as well as body composition, were similar between the groups. Additionally, any differences between groups were observed on endothelial reactivity tests. Nevertheless, we noted an association between cortisol levels after 1 mg-dexamethosone suppression test (1 mg-DST) and the duration of post-occlusive reactive hyperemia tested on microcirculation (r = 0.30; p = 0.03). NFAI patients require more antihypertensive drugs to achieve blood pressure control (p = 0.04). The number of antihypertensive drugs used to control blood pressure correlated with cortisol levels after 1 mg-DST (r = 0.29; p = 0.03).

CONCLUSIONS

Since both groups herein investigated had a high frequency of metabolic syndrome and ASCVD risk, it might explain similarities observed on endothelial reactivity. Nevertheless, prolonged reactive hyperemia response on microcirculation was correlated with cortisol levels under suppression.

Heart Disease and Stroke Statistics-2021 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2021 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors related to cardiovascular disease.

RESULTS

Each of the 27 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Predictors of Metabolic Syndrome in Adults and Older Adults from Amazonas, Brazil

Metabolic syndrome has been considered a factor of vulnerability and a major public health problem because it increases the risk of cardiovascular disease and type 2 diabetes. The present study from Amazonas, Brazil aimed to estimate the prevalence of the individual and general components of metabolic syndrome in adults and older adults and identify the independent predictors of metabolic syndrome. The sample of the present cross-sectional study comprised 942 participants (590 women), with a mean age of 59.8 ± 19.7 (range: 17.5 to 91.8). Blood pressure in men (62.5%), abdominal obesity in women (67.3%), and lower high-density lipoprotein cholesterol (HDL-C) in both (52.2% in men and 65.0% in women) were the most prevalent individual risk factors for metabolic syndrome. Women had a higher prevalence of abdominal obesity (p < 0.001), low HDL-C (p < 0.001), and metabolic syndrome (p < 0.001) than men; however, opposite results were seen in men for blood pressure (p < 0.001). The overall prevalence of metabolic syndrome was 47.5%. Advanced age, being female, having a higher body mass index, and a having lower educational level independently increased the odds of metabolic syndrome. Due to the association of metabolic syndrome with deterioration of health status and increased vulnerability, this study sustains the need for early public health interventions in the Amazonas region.

Diabetic Patients with Cardiovascular Disease Show More Metabolic Syndrome than Nondiabetic Patients: Multicentric Study in the Northeast of Brazil

Background: Diabetes mellitus (DM) is associated with a higher prevalence of metabolic syndrome (MS) and cardiovascular mortality. However, few Brazilian studies evaluated MS in diabetic individuals with cardiovascular disease (CVD). Nevertheless, the objective of this study was to compare the prevalence of MS in cardiac patients with and without DM. Methods: Cross-sectional study of BALANCE Program Trial with patients with CVD, ≥45 years old, who had been attending specialized ambulatories on cardiovascular health, in eight states in the Northeast of Brazil. The components of MS were evaluated by following the criteria of National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) and Joint Interim Statement (JIS). In addition, there were investigated different indexes of abdominal obesity, variables related to lifestyle, and food intake. The statistical analysis included descriptive statistics and the Student's t-test, Mann-Whitney, and chi-squared tests for the comparison of groups. There were significant values of P < 0.05. Results: Six hundred forty-seven individuals were evaluated with average (standard deviation) age of 63.1 (9.3) years, being 50.5% females and 40.3% diabetic patients. When the groups of patients who were diabetic and the nondiabetic ones, the first showed higher percentage of obesity (38.5% vs. 23.2%, P < 0.001), of high waist circumference (84.8% vs. 71.9%; P < 0.001), higher waist-height ratio [0.6 (0.6-0.7) vs. 0.6 (0.5-0.6); P < 0.001], conicity index [1.35 (1.29-1.39) vs. 1.32 (1.27-1.38); P = 0.004], and prevalence of MS, because of the criteria of NCEP ATP III (98.8% vs. 80.4%; P < 0.001), as well as the criteria of JIS (99.2% vs. 89.3%; P < 0.001). The component of higher frequency was high blood pressure and/or hypertension (95.0%), followed by hypertriglyceridemia (93.0%). There were no differences regarding age, lifestyle, and food intake. Conclusions: Diabetic individuals with CVD showed more prevalence of MS and more abdominal obesity than nondiabetic individuals. ClinicalTrials.gov ID: NCT01620398.

Prevalence of overweight and metabolic syndrome, and associated sociodemographic factors among adult Ecuadorian populations: the ENSANUT-ECU study

BACKGROUND

Obesity and metabolic syndrome (MetS) are key risk factors for type 2 diabetes and cardiovascular disease. Little information exists on the prevalence of obesity and MetS in Latin America and specifically in Ecuador. We aimed to estimate the prevalence of overweight, obesity, and MetS among adults in Ecuador.

METHODS

We analyzed data from a nation-wide population-based survey in Ecuador (ENSANUT-ECU) among 10,318 participants (3684 men, 6634 women; age range: 18-59 years) conducted in 2012. Data related to residential location (urban versus rural), altitude (< 500, 500-1500 or > 1500 m above sea level (MASL)), region (highland, coast, amazon, or Galápagos), and socioeconomic status were collected. BMI, waist circumference, blood lipids, glucose, and blood pressure were measured by trained fieldworkers following standardized procedures.

RESULTS

The age-standardized prevalence of overweight was 39.5%; 22.3% was obese; and 31.2% had MetS. The prevalence of obesity, low HDL-cholesterol, and abdominal obesity were higher in women than in men, whereas men had a higher prevalence of hypertension (p < 0.05). Sex differences were not observed regarding the prevalence of combined MetS. Prevalence of both obesity and MetS was higher in urban areas, at low altitude regions (coast and Galapagos), and at high socioeconomic status (all p < 0.05).

CONCLUSIONS

Prevalence of obesity and MetS in Ecuador are high. There are important demographic differences in the prevalence of MetS between Ecuadorian subpopulations that requires targeted research and prevention efforts, to hold and reduce the current public health problem of metabolic disorders.

Contribution of minimally processed and ultra-processed foods to the cardiometabolic risk of Brazilian young adults: a cross-sectional study

Introduction

Introduction: the simultaneous increase in the prevalence of cardiometabolic diseases and in the consumption of ultraprocessed foods (UPF) suggests a possible relationship between UPF and cardiometabolic risk (CMR). Objective: to evaluate the association between food consumption, according to the degree of processing, and CMR in young adults. Methods: this is a comparative cross-sectional study in 120 Brazilian young adults aged 18-25 years, categorized by the presence of CMR. Food consumption was investigated using a semi-quantitative food frequency questionnaire, and classified according to the extent of food processing. Food groups and tertiles in grams of unprocessed, minimally processed (MPF), processed and ultra-processed foods (UPF) were compared using the Kruskal-Wallis test. The associations of food consumption, according to level of processing (MPF and UPF), with CMR components were evaluated using logistic regression models. Results: a high caloric contribution of UPF was observed in the diet of this study population. The total energy intake from lipids in all foods (p = 0.04) and in UPF (p = 0.03) was greater in the group with CMR. A greater consumption of UPF was a risk factor for abdominal obesity (OR = 1.09; 95 % CI = 1.00-1.18) while a greater consumption of MPF was protective for LDL-c alterations independently of sex, physical activity, and alcohol intake (OR = 0.70; 95 % CI = 0.50-0.98). Conclusions: UPF contributed to a greater caloric intake from fat in the CMR, and was a risk factor for abdominal obesity. MPF was an independent protective factor for LDL-c alterations.

Incidence of metabolic syndrome in adults with healthy weight, normal weight obesity, and overweight/obesity

OBJECTIVES

The aim of this study was to estimate the incidence of metabolic syndrome (MetS) in individuals with a healthy weight (HWI), normal weight obesity (NWO), or overweight/obesity (OWO).

METHODS

In all, 787 adults belonging to a 1978/1979 birth cohort from Ribeirão Preto were placed into one of three groups: HWI (body mass index [BMI] ≥18.5 and <25 kg/m² + ∑skinfolds ≤90th percentile); NWO (BMI ≥18.5 and <25 kg/m² +∑skinfolds >90th percentile); and OWO (BMI ≥25 kg/m² +∑skinfolds >90th percentile). Those diagnosed with MetS at the 23 to 25 y of age were excluded according to Joint Interim Statement criteria. The incidence of MetS and its components in individuals 37 to 39 y of age was evaluated by Poisson regression with robust estimation of variance, which was adjusted for family income; physical activity level; and daily intake of calories, lipids, and added sugar.

RESULTS

MetS was detected in 279 adults at 37 to 39 y of age. NWO and OWO individuals showed higher risk ratios (RRs) for the development of MetS (RR,1.87; 95% confidence interval [CI], 1.36-2.57; RR, 1.61; 95% CI, 1.29-2.03), increased blood glucose levels (RR, 1.77; 95% CI, 1.12-2.79; RR, 1.51; 95% CI, 1.12-2.04), and increased waist circumferences (RR, 1.46; 95% CI, 1.32-1.61; RR, 1.50; 95% CI, 1.38-1.62). There was a higher risk for increased blood pressure (RR, 1.72; 95% CI, 1.35-2.19) among OWO individuals, but not among those with NWO.

CONCLUSION

Individuals with NWO have a risk ratio for MetS similar to individuals with OWO. This demonstrates the need to assess body fat percentages, even in BMI-designated normal weight individuals, both for prevention and management of obesity.

The Prevalence of Metabolic Syndrome in Ethiopian Population: A Systematic Review and Meta-analysis

Background

The metabolic syndrome is a clustering of hyperglycemia/insulin resistance, hypertension, dyslipidemia, and obesity which are risk factors for cardiovascular disease, type 2 diabetes and stroke, and all-cause mortality. The burden of metabolic syndrome is emerging alarmingly in low- and middle-income countries such as Ethiopia; however, there is lack of comprehensive estimation. This study aimed to determine the pooled prevalence of metabolic syndrome in Ethiopia.

Methods

This systematic review and meta-analysis included original articles of observational studies published in the English language. Searches were carried out in PubMed, Google Scholar, and Africa Journals from conception to August 2020. A random-effects model was used to estimate the pooled prevalence of metabolic syndrome in Ethiopia. Heterogeneity was assessed using the I 2 statistic. Subgroup analysis was also conducted based on sex/gender and study subjects. Egger's test was used to assess publication bias.

Results

Electronic and gray literature search retrieved 942 potentially relevant papers. After removing duplicates and screening with eligibility criteria, twenty-eight cross-sectional studies were included in this meta-analysis. The pooled prevalence of metabolic syndrome in Ethiopia was found to be 34.89% (95% CI: 26.77, 43.01) and 27.92% (95% CI: 21.32, 34.51) by using NCEP/ATP III and IDF criteria, respectively. The weighted pooled prevalence of metabolic syndrome was higher in females 36.74% (95% CI: 20.72, 52.75) and 34.09% (95% CI: 26.68, 41.50) compared to males 22.22% (95% CI: 14.89, 29.56) and 24.82% (95% CI: 18.34, 31.31) by using IDF and NCEP/ATP III criteria, respectively. Subgroup analysis based on the study subjects using NCEP/ATP III showed that the weighted pooled prevalence was 63.78%(95% CI: 56.17, 71.40), 44.55% (95% CI: 30.71, 52.38), 23.09% (95% CI: 19.74, 26.45), 20.83% (95% CI: 18.64, 23.01), and 18.45% (95% CI: 13.89, 23.01) among type 2 diabetes patients, hypertensive patients, psychiatric patients, HIV patients on HAART, and working adults, respectively. The most frequent metabolic syndrome components were low HDL-C 51.0% (95% CI: 42.4, 59.7) and hypertriglyceridemia 39.7% (95% CI: 32.8, 46.6).

Conclusions

The findings revealed an emerging high prevalence of metabolic syndrome in Ethiopia. Therefore, early intervention is required for the primary prevention of the occurrence of metabolic syndrome and the further reduction of the morbidity and mortality related to it.

Metabolic syndrome in type 2 diabetic patients: a review of current evidence

The metabolic syndrome (MS) is a set of metabolic disturbances, represented by various cardiovascular risk factors which are generally associated with the central accumulation of fat and the resistance to insulin. Inadequate changes in eating behaviours and weight loss, which are associated to taking part in regular physical activity, are considered to be primary and first choice therapies for the treatment of MS, as they assist in the reduction of the abdominal girth and visceral fat, improve the sensibility to insulin and reduce the plasmatic concentrations of glucose and triglycerides, raise the values of high density lipoproteins and, consequently decrease the risk factors which contribute to the development of type 2 diabetes. The MS is a current discussion theme in the health field as it is related to illnesses/diseases, which not only cause a worldwide high mortality rate but show increasing incidence. Type 2 diabetes is characterised by a deregulation of the carbohydrates, lipids and proteins found in the metabolism and result in diminished secretion of insulin, resistance to insulin or a combination of both. Type 2 diabetes is the most form of diabetes of the first 3 types of diabetes, representing 90% of all cases. Diabetes is a chronic and complex disease which requires a strict medical follow-up so as to reduce the risks and obtain strategies for its control. The fast-epidemiological global evolution which has been registered in the last few years, leads to it being considered one of the pandemics of the 21st century. In this non-systematic and advanced review of the MS in type 2 diabetic patients, several articles were consulted, and some recently published studies were analysed.

Plasma metabolomics are associated with metabolic syndrome: A targeted approach

OBJECTIVES

Advances in metabolomic tools have allowed us to gain a more comprehensive understanding of metabolic syndrome (MetS). The aim of this study was to evaluate the association between plasma metabolomic profiles and MetS.

METHODS

For this study, adults without diabetes, chronic kidney disease, stroke, heart disease, or cancer and with full metabolomics, biochemical, and dietetic data available, representing a subsample of the Health Survey of Sao Paulo study (ISA-Capital; N = 130), were included. The joint interim statement consensus criteria were used for diagnosing MetS. Absolute quantification (µmol/L) of blood metabolites was achieved by targeted quantitative profiling of annotated metabolites by electrospray ionization tandem mass spectrometry in plasma samples. Mean differences in the compounds for MetS were evaluated by linear regression adjusted for confounding factors.

RESULTS

Serine was inversely associated with MetS (β = -15.04; P = 0.014). In glycerophospholipids with acyl-alkyl bonds, there was an inverse association with MetS, including phosphatidylcholine (PC) ae C42:5 (β = -0.15; P = 0.040), PC ae C44:5 (β = -0.15; P = 0.046), PC ae C40:4 (β = -0.21; P = 0.014) and PC ae C44:4 (β = -0.04; P = 0.032).

CONCLUSION

Plasma metabolomic profiles were associated with MetS, especially the amino acid serine and some acyl-alkyl PCs.

Metabolic Syndrome in HIV-patients in Antiretroviral Therapy

INTRODUCTION

The global prevalence of metabolic syndrome (MS) among people living with HIV/AIDS varies from 20% to 33%.

OBJECTIVE

to estimate the prevalence of metabolic syndrome and associated factors in a group of HIV-infected patients on antiretroviral therapy.

METHODS

This is a cross-sectional study with HIV-infected patients from a reference center in Bahia, Brazil. We evaluated clinical, socio-demographic and anthropometric data. MS was defined according to the guidelines of International Diabetes Federation.

RESULTS

We evaluated 152 patients with mean age of 47.3±11.6 years, 59.2% male. The main comorbidities detected were diabetes (3.3%) hypertriglyceridemia (9.3%) and metabolic syndrome (MS,38.2%). Patients with MS were predominantly women (55.2% vs 31.9%; p=0.005), older [52.1 (10.4) vs 44.3 (11.3); p<0.001], and had overweight (74.1% vs 23.4%; p<0.001). After multivariate analysis MS remained associated with age (OR = 1.076; 95% CI: 1.030 - 1.125), female sex (OR = 2.452; 95% CI: 1.114 - 5.374) and family history of hypertension (OR = 3.678; 95% CI: 1.431 - 9.395).

CONCLUSION

Almost half of the HIV-infected patients in Bahia presents with MS which seems to be driven by classical risk factors.

Supplementation with Resveratrol, Piperine and Alpha-Tocopherol Decreases Chronic Inflammation in a Cluster of Older Adults with Metabolic Syndrome

Metabolic Syndrome (MetS) is increasing worldwide regardless of culture, genetic, gender, and geographic differences. While multiple individual risk factors, such as obesity, hypertension, diabetes, and hyperlipidemia, can cause cardiovascular disease (CVD), it is the intercurrence of these risk factors that defines MetS as a cluster that creates an environment for atherosclerosis and other manifestations of CVD. Despite the advances in the knowledge and management of each of the components of MetS, there are two molecular biology processes, chronic inflammation and oxidative stress, which are still underdiagnosed and undertreated. In order to assess the effect of a dietary supplement on chronic inflammation in MetS, we conducted a clinical trial with volunteers receiving a formula composed of resveratrol, piperine and alpha tocopherol (FRAMINTROL^®), together with their habitual treatment, for three months. The inflammatory state was evaluated by ultrasensitive C reactive protein (US CRP) and ferritin in plasma, and oxygen consumption and chemiluminescence in neutrophils. The results showed that ferritin decreased by 10% (p < 0.05), US-CRP by 33% (p < 0.0001), oxygen consumption by 55% (p < 0.0001), and spontaneous chemiluminiscence was by 25% (p < 0.005) after treatment. As far as we know, this is the first study showing a chronic inflammation decrease in MetS patients due to the administration of a biopower Resveratrol-piperine and alpha tocopherol dietary supplement together with conventional therapy.

Positive psychological characteristics in patients with metabolic syndrome associated with prospective changes in diet and anthropometric factors

The prevalence of metabolic syndrome (MetS) is increasing worldwide, and diet therapy plays a key role in treating this disease. Since most patients show difficulties in adhering to nutritional interventions, research on the association of positive psychological characteristics with greater engagement in physical health is relevant to this field. The present study aimed to evaluate the association between positive psychology attributes (optimism, hope, self-esteem, positive/negative affect and life satisfaction) and changes in diet quality and anthropometric parameters of individuals with MetS who received nutritional counseling. The study assessed 63 patients at a nutrition outpatient clinic. Anthropometric parameters and 24-hour food recall data (for evaluation of the Brazilian Healthy Eating Index-Revised-BHEI-R) were collected at the first visit and subsequent return visit (on average five months later). Psychological data were collected at the first visit using validated and standardized scales. The results were adjusted in relation to the depression scores of the patients, which were evaluated using the Beck Depression Inventory-II (BDI-II). Changes in anthropometric factors and in the BHEI-R were assessed, and their associations with the psychological attributes were investigated. The results indicated that positive affect and hope were associated with improvement in the BHEI-R scores (Cohen effect sizes -0.65 and -0.58; p = 0.012 and 0.025, respectively). A significant association was also observed between optimism and a reduction in abdominal circumference (Cohen effect size 0.56; p = 0.031). The associations remained significant even after adjusting for the BDI-II scores (p = 0.022, p = 0.037 and p = 0.05, respectively). No statistically significant associations were observed for the other attributes assessed.The study suggests that some attributes may have a greater influence on the nutritional treatment of MetS and that future studies should be conducted in order to enable effective multidisciplinary interventions to treat MetS.

Prevalence of Metabolic Syndrome by different definitions, and its association with type 2 diabetes, pre-diabetes, and cardiovascular disease risk in Brazil

BACKGROUND AND AIMS

Metabolic Syndrome (MS) is increasing in developing countries. Different definitions of MS lead to discrepancies in prevalence estimates and applicability. We assessed the prevalence of MS as defined by the International Diabetes Federation (IDF), modified National Cholesterol Education Program Adult Treatment Plan III (Modified NCEP) and Joint Interim Statement (JIS); compared the diagnostic performance and association of these definitions of MS with pre-diabetes, type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) risk.

METHODS

A total of 714 randomly selected subjects from Northeastern Brazil were investigated in a cross-sectional study. Sociodemographic, anthropometric, and clinical data were recorded. Diagnostic test performance measures assessed the ability of the different MS definitions to identify those with pre-diabetes, T2DM and increased CVD risk.

RESULTS

The adjusted prevalence of MS was 36.1% applying the JIS criteria, 35.1% the IDF and 29.5% Modified NCEP. Women were more affected by MS according to all definitions. MS was significantly associated with pre-diabetes, T2DM and CVD risk following the three definitions. However, the JIS and IDF definitions showed higher sensitivity than the Modified NCEP to identify pre-diabetes, T2DM and CVD risk. The odds ratios for those conditions were not significantly different when comparing the definitions.

CONCLUSIONS

MS is highly prevalent in Brazil, particularly among those with pre-diabetes, T2DM, and high CVD risk. The IDF and JIS criteria may be better suited in the Brazilian population to identify pre-diabetes, T2DM and CVD risk. This may also signify the importance of the assessment of MS in clinical practice.

Prevalence of the Metabolic Syndrome and its components in the Brazilian adult population

We estimated the prevalence of the Metabolic Syndrome (MetS) and its components in the Brazilian population according to sociodemographic factors. This is a cross-sectional population-based study that used laboratory data from the National Health Survey. We estimated the prevalence of MetS and its components with 95% confidence intervals and the unadjusted and adjusted prevalence ratio (PR) with the Poisson regression. MetS prevalence ratio was 38.4%. High waist circumference (WC) (65.5%) and low HDL cholesterol (49.4%) were the most prevalent components, including in the youngest people. MetS and its components were more frequent among women (41.8%), individuals with low schooling (47.5%), and older adults (66.1%). In the adjusted analysis, females (PR = 1.16; 95% CI 1.08-1.24), older adults (PR = 3.69; 95% CI 3.26-4.17), and low schooling (PR = 1.32; 95% CI 1.17-1.49) were associated with MetS. MetS was prevalent in the Brazilian population, especially among women, individuals with low schooling, and older adults. High WC and low HDL cholesterol were the most prevalent components, with the aggravating high prevalence factor in young adults. These findings reveal the need to consider laboratory data for a more accurate analysis of this condition, which can be challenging at the national level.

Metabolic syndrome and its components in adult hypopituitary patients

PURPOSE

To evaluate the prevalence of metabolic syndrome (MetS) and its components in adult hypopituitary patients.

PATIENTS AND METHODS

Retrospective, cross-sectional analysis of a cohort of hypopituitary adult patients followed in a single reference center for pituitary diseases. MetS was defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. Patients with 18 years or older, presenting two or more anterior pituitary deficiencies associated or not with diabetes insipidus (DI), were included, while patients with hypopituitarism due to Acromegaly or Cushing's disease were excluded.

RESULTS

We studied 99 hypopituitary patients (52 males, mean age 50.1 ± 16.3 years, mean age at diagnosis 33.7 ± 17.6 years) who have been followed for a mean time of 15.9 ± 10.1 years. Hypothalamic-pituitary tumors and non-tumoral etiologies were observed in 53.4% and 46.6% of the cases, respectively. FSH/LH, GH, TSH, ACTH deficiency and DI was present in 99%, 98.6%, 96%, 81.8%, and 23.2%, respectively. The prevalence of MetS was 39.4% and was significantly higher in patients older than 50 years (p = 0.02), overweight/obese (p < 0.001), with hypopituitarism diagnosed in adult life (p = 0.02), who did not replace GH (p = 0.004) and in smokers (p = 0.007). In the logistic regression model, body mass index (BMI) and GH replacement were significantly associated with the presence of MetS. Reduced HDL cholesterol was the most prevalent component of MetS in hypopituitary patients.

CONCLUSIONS

MetS is a common finding in adult hypopituitary patients, which is mainly influenced by increased BMI and untreated GH deficiency. Trial Registration number (Plataforma Brasil): CAAE 51008815.2.0000.0096 (May 31, 2017) .

Level of leisure-time physical activity and its association with the prevalence of metabolic syndrome in adults: a population-based study

OBJECTIVE

To analyze the associations between changes in the level of leisure-time physical activity in adults and the prevalence of metabolic syndrome.

METHODS

This is a population-based study conducted with 818 adults aged 20 years or older from Florianópolis, Santa Catarina, Southern Brazil, between 2009 and 2014. We tested the association of maintenance and/or changes in the level of physical activity with the prevalence of metabolic syndrome, adjusted for sociodemographic variables (gender, age, schooling, income, marital status, and ethnicity) and smoking habits. We used logistic regression and estimated the odds ratios (OR) and their respective confidence intervals (95%CI).

RESULTS

The overall prevalence of metabolic syndrome was 30.9% (95%CI 27.2-34.7). Regardless of adjustment variables, adults who ceased to be active and/or remained physically inactive during leisure time in the study period presented, respectively, 108 and 124% higher odds of developing metabolic syndrome (OR=2.08; 95%CI 1.30-3.33 and OR=2.24; 95%CI 1.38-3.65). Women and individuals younger than 45 years showed lower odds of having metabolic syndrome.

CONCLUSIONS

This sample presented a significant association between remaining or becoming inactive and a greater chance of developing metabolic syndrome.

Metabolic syndrome: physical inactivity and socioeconomic inequalities among non-institutionalized Brazilian elderly

OBJECTIVE

Evaluate the association between Metabolic Syndrome (MetS), physical activity and socioeconomic conditions among non-institutionalized elderly individuals.

METHODOLOGY

Cross-sectional study with, elderly individuals (≥ 60) living in the city of São Paulo. MetS was evaluated by means of the National Cholesterol Education Program criteria, the Adult Treatment Panel III. Descriptive and bivariate analyses were performed, followed by multiple logistic regression with a 5% significance level. An attributable fraction (AF) and a proportional attributable fraction (PAF) were calculated in relation to physical activity. The magnitude of the socioeconomic inequalities was evaluated using the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII).

RESULTS

The prevalence of MetS was 40.1%, and 23.3% of the individuals had at least one MetS' component. Physically inactive elderly had higher chances of having MetS. The prevalence of MetS was higher among those with lower education levels in both absolute and relative terms. AF and PAF were significant among the inactive individuals and for the total population.

CONCLUSION

This study demonstrated that physical activity and schooling are significantly associated with MetS, highlighting the importance of these factors for the control of this syndrome.

Latin American Consensus on the management of hypertension in the patient with diabetes and the metabolic syndrome

: The prevalence of hypertension, type 2 diabetes mellitus (DM2) and the metabolic syndrome continues to increase in Latin America, while the rates of diagnosis, treatment and control of these disorders remain low. The frequency of the risk factors that constitute the metabolic syndrome and are associated with an increased risk of cardiovascular disease has not diminished since the publication of the previous consensus. This document discusses the socioeconomic, demographic, environmental and cultural characteristics of most associated Latin American countries and partially explains the lack of better results in improving clinical and public health actions that allow high morbidity and mortality rates caused by cardiovascular diseases and DM2 to be reduced through programs aligned with the so-called precision medicine, which should be predictive, preventive, personalized and participatory. The Consensus ratifies the diagnostic criteria expressed in the previous consensus to define hypertension and DM2 but, for the metabolic syndrome, and in the absence of evidence, the recommendation is to implement a cohort study that determines the abdominal perimeter value associated with hard outcomes, such as DM2 and CVD. Meanwhile, we recommend modifying the criterion to more than 94 cm in men and more than 84 cm in women according to WHO recommendations. We also recommend the carrying out of a study that identifies the situation of hypertension and DM2 in people of African ancestry who, in Latin America, exceed 75 million and whose epidemiology does not include solid studies. With respect to the proposed therapeutic targets, we recommended maintaining those defined in the previous consensus, but insisting that early pharmacological management of prediabetes with metformin should be introduced, as should the treatment of diabetic hypertensive patients with a combination therapy of two fixed-dose antihypertensive drugs and management with statins. To increase adherence, the use of different drugs combined in a single pill (polypill) is recommended. The simplification of the therapeutic regimen is accompanied by greater control of cardiovascular risk factors, both in primary and secondary prevention, and has been shown to be cost-effective. The consensus recommends the use of the currently available polypill combining an angiotensin-converting enzyme inhibitor, a statin and aspirin for secondary cardiovascular prevention and in patients with a high cardiovascular risk, such as hypertension patients with DM2.

The effect of diet on oxidative stress and metabolic diseases-Clinically controlled trials

Oxidative stress is associated with several chronic diseases. It is acknowledged that molecules damaged by reactive oxygen species activate the inflammatory process and that this response increases the production of free radicals. Modifications in a diet can improve or decrease redox state markers. The aim of this revision was to provide an update of clinical controlled trials, to assess changes in diet and markers of oxidative stress in subjects with metabolic diseases. They were investigated randomized controlled intervention studies (RCTs) published in MEDLINE (U.S. National Library of Medicine, National Institutes of Health) that were conducted in subjects with obesity, hypertension, diabetes, or dyslipidemia; with dietary intervention; where markers of oxidative stress have been evaluated and published in the last 5 years. Food antioxidants, hypocaloric diets with loss of adipose tissue, substitution of animal protein by vegetable, and changes in the microbiota improve antioxidant status in people with chronic disease. PRACTICAL APPLICATIONS: Hyperglycemia in diabetes mellitus and adipose tissue in obesity are known to trigger oxidative stress. Oxidative stress, in turn, decreases insulin sensitivity and favors an inflammatory state producing adhesion molecules. Oxidative stress and adhesion molecules, can increase blood pressure and oxidation of lipoproteins, that ultimately could lead to a cerebrovascular event. Consumption of high-antioxidant and polyphenol foods increases plasma antioxidant capacity and decreases oxidative stress markers in people with diabetes, obesity, hypertension, and hypertriglyceridemia. In addition, weight loss caused by caloric restriction with or without exercise increases the endogenous antioxidant capacity. Therefore, it is likely that the combination of a hypocaloric diet with a high content of antioxidants and polyphenols will have a greater effect. Other dietary changes with antioxidant effect, such as the substitution of animal for vegetable protein or the addition of fiber, might be mediated by changes in the microbiota. However, this aspect requires further study.

Dietary total antioxidant capacity significantly interacts with 6-P21 rs2010963 gene polymorphisms in terms of cardio-metabolic risk factors in patients with metabolic syndrome

OBJECTIVE

Gene- nutrient interaction might possibly be involved in the pathogenesis of metabolic syndrome and its components. In the current report, the association between antioxidant potential of the diet with 6P21 rs2010963 gene polymorphism in patients with metabolic syndrome has been evaluated. Two hundred fifty-four patients with metabolic syndrome were enrolled. Total dietary antioxidant capacity (TAC) has been estimated and anthropometric assessments were assessed. Biochemical assays including serum glucose, matrix metalloproteinase-3, liver enzymes and lipid profiles were also assessed. Polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) method was used for determination of 6P21 rs2010963 polymorphism.

RESULTS

Dietary vitamin E score was significantly higher in GC genotype compared with other genotypes (P = 0.035). Patients in CC genotype of 6P21 rs2010963 had significantly higher body mass index (BMI), fasting blood sugar and liver enzymes (P < 0.05). Being in the higher dietary TAC scores was also associated with lower liver enzymes. The interaction between 6P21 rs2010963 and dietary TAC significantly affected BMI, FBS and diastolic blood pressure (P < 0.05). According to our findings the CC genotype of 6P21 rs2010963 could be considered as the possible risk factor for obesity and metabolic disorders among patients with metabolic syndrome.

Heart Disease and Stroke Statistics-2020 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals.

RESULTS

Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Prevalence of Metabolic Syndrome Among Patients with Psoriasis Treated with TNF Inhibitors and the Effects of Anti-TNF Therapy on Their Lipid Profile: A Prospective Cohort Study

Background: Tumor necrosis factor (TNF) is an important inflammatory cytokine in the pathogenesis of psoriasis and metabolic syndrome (MS). Patients with psoriasis have higher rates of MS; therefore, some authors suggest an MS screening within this population. In addition, TNF inhibitor treatment often modifies the metabolic profiles of these patients. This study describes the epidemiological, clinical, and laboratory characteristics of patients with psoriasis undergoing anti-TNF treatment and evaluates whether anti-TNF treatments influence changes in their metabolic parameters. Methods: A prospective 6-month cohort study followed patients who underwent three consecutive consultations at 0, 3, and 6 months. The sample composed of 83 patients with psoriasis using anti-TNF. Results: The mean age and disease duration of the patients were 48 ± 11 and 16 ± 9 years, respectively. Most patients were men (61.5%). The prevalence of MS was 36%, and high rates of abdominal obesity (59%) and overweight (82%) were observed. Anti-TNF treatment significantly altered total cholesterol levels (195.5 ± 36.17 vs. 183.5 ± 41.23, P = 0.04) and low-density lipoprotein (LDL) cholesterol levels (128.5 ± 31.26 vs. 113 ± 36.31, P = 0.04). This study has some limitations, such as small sample size, brief follow-up period (6 months), patient recruitment from a tertiary-level referral center, and no control group. Conclusions: Patients with psoriasis have high rates of MS, overweight, and obesity, but anti-TNF treatment seems to improve the metabolic profile of these patients by decreasing their total and LDL cholesterol levels.

Individual and Combined Components of Metabolic Syndrome with Chronic Kidney Disease in Individuals with Hypertension and/or Diabetes Mellitus Accompanied by Primary Health Care

PURPOSE

To identify the associations between MetS and its components and chronic kidney disease (CKD) in a population with arterial hypertension (AH), or diabetes mellitus (DM) accompanied by the Primary Health Care (PHC).

PATIENTS AND METHODS

A cross-sectional study with 788 individuals diagnosed with AH and/or DM followed by PHC of Viçosa, Brazil. Anthropometric, biochemical and clinical measures were performed for the diagnosis of MetS and CKD. MetS was identified using the NCEP-ATPIII criteria. CKD was identified by estimating the glomerular filtration rate using the CKD-EPI equation. Logistic regression models were used to estimate the chances of CKD associated with MetS and its components and specific combinations of components.

RESULTS

The prevalence of MetS reported in the population was 65.4%, that of hidden CKD was 15.4%. The prevalence of CKD among participants with MetS was 75.2%. The most prevalent component of MetS in the population was AH (96.7%). Elevated fasting blood glucose, central obesity, and reduced HDL-c were significantly associated with an increased chance of CKD (OR = 2.80, 95% CI 1.76-4.45, OR = 1.68, 95% CI, 05-2.71, OR = 1.61, CI 95% 1.03-2.50, respectively). For the multivariate adjustment, the participants with MetS were 2 times more likely to have CKD than those without MetS (OR = 2.07; 95% CI, 1.25-3.44). The combination of three components of MetS high blood pressure, abdominal obesity and elevated fasting blood glucose and the combination of four components of MetS high blood pressure, reduced HDL-c, high fasting blood glucose and abdominal obesity were associated with increased odds of CKD (OR = 2.67, CI 95% 1.70-4.20, OR = 2.50, CI 95% 1.55-4.02, respectively).

CONCLUSION

MetS, as well as its individual or combined components were independently associated with CKD in the population with AH and/or DM accompanied by PHC.

Carbohydrate intake and risk of metabolic syndrome: A dose-response meta-analysis of observational studies

BACKGROUND AND AIMS

Epidemiological association studies have reported inconsistent findings on the relationship between carbohydrate intake and risk of metabolic syndrome (MetS). Therefore, we aimed to conduct the first dose-response meta-analysis to investigate this effect.

METHODS AND RESULTS

A systematic search in PubMed and Web of Science databases from their inception to June 01, 2019, together with relevant literature scrutiny, was performed to identify related studies for inclusion into the meta-analysis. We calculated the odds ratios (ORs) with 95% confidence intervals (CIs) using a random effects model. Furthermore, subgroup, sensitivity, heterogeneity, and publication bias analyses were performed. This meta-analysis included 14 cross-sectional and four cohort studies, totaling 284,638 participants and 69,554 MetS cases. The highest versus the lowest carbohydrate intake values were associated with an increased risk of MetS (OR: 1.253, 95% CI: 1.147-1.368), with moderate heterogeneity (I² = 54.5%). Using dose-response analysis, we found a linear association between carbohydrate consumption and MetS risk with a corresponding OR of 1.026 (95% CI, 1.004-1.048) and with significant heterogeneity (I² = 82.0%) at 5% energy intake from carbohydrates. We have found similar results using subgroup analyses for major study characteristics and adjustment for confounders. Sensitivity analysis further enhanced the robustness of the results, and no publication bias was detected.

CONCLUSION

Carbohydrate intake is associated with an increased risk of developing MetS. Therefore, additional large prospective cohort studies are warranted to confirm our findings.

Metabolic syndrome (MetS) and associated factors in middle-aged women: a cross-sectional study in Northeast Brazil

We determined the prevalence of Metabolic Syndrome (MetS) and associated factors in 419 women (aged 40 to 65 years) in Northeast Brazil in a cross-sectional study conducted from April to November 2013. We defined MetS using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. Socio-demographic variables, reproductive factors, lifestyle factors, anthropometrics, body composition, quality of life, and physical performance were assessed for their associations. We constructed multivariate Poisson regression models to estimate prevalence rate ratios (PRR) and 95% confidence intervals (CI). We identified 275 (65.6%) cases of MetS. The three most prevalent indicators were obesity (73.5%), reduced high-density lipoprotein level (63.0%), and elevated blood pressure (60.9%). In the final adjusted model, black race (PR 1.30, 95% CI: 1.07-1.57), lower grip strength/body mass index (PR 1.31, 95% CI: 1.15-1.50), and low estradiol levels (PR 1.17, 95% CI: 1.00-1.35) were associated with MetS. MetS is a long-term threat to the health of middle-aged women and a potential public health burden. These results may help in developing health promotion strategies to prevent morbidity and mortality associated with MetS in this vulnerable population.

Metabolic Syndrome, Physical Activity, and Medication-Related Expenditures: A Longitudinal Analysis

Background: Metabolic syndrome (MetS) is a combination of risk factors for cardiovascular disease and type 2 diabetes mellitus. The prevalence of MetS worldwide is increasing. There is no study investigating the economic burden of MetS, especially in developing countries, on medication-related expenditure. The aim of this study was to investigate the association of medication-related expenditures with MetS and to explore how physical activity (PA) may influence this association. Methods: A total of 620 participants, 50 years or older, randomly selected in the city of Bauru, Brazil. Participants were followed from 2010 to 2014, and data on health care expenditure were collected annually. PA questionnaire was applied at baseline, 2 (2012), and 4 (2014) years later. Results: Mean age was 64.7 (95% confidence interval, 64.1–65.3). MetS was associated with higher medication expenditure related to diseases of the circulatory (P <.01) and endocrine (P <.01) systems. MetS explained 17.2% of medication-related expenditures, whereas PA slightly attenuated this association, explaining 1.1% of all health care costs. Conclusion: This study demonstrates that MetS has a significant burden on health care expenditures among adults, whereas PA seems to affect this phenomenon significantly, but in low magnitude.
