Determinants of metabolic syndrome and its prognostic implications among stroke patients in Africa: Findings from the Stroke Investigative Research and Educational Network (SIREN) study

BACKGROUND

The prognostic implications of metabolic syndrome (METS) among African stroke patients are poorly understood. This study aimed to investigate the determinants of METS and its prognostic implications among Africans with newly diagnosed stroke in the SIREN study.

METHODS

We included stroke cases (adults aged >18 years with CT/MRI confirmed stroke). The validated tools comprehensively evaluated vascular, lifestyle, and psychosocial factors. We used logistic regression to estimate adjusted odds ratios (OR) with 95% CIs for the association between METS and risk factors. We also computed the prediction power of the domain of covariates in a sequential manner using the area under the receiver operating curve (ROC) curve.

RESULTS

Among 3998 stroke subjects enrolled in the study, 76.8% had METS by at least one of the clinical definitions. Factors associated with METS were age > 50 years (OR- 1.46, CI-1.19-1.80), male gender (OR 4.06, CI- 3.28-5.03), income >100USD (OR1.42, CI-1.17-1.71), stress (OR1.46, CI-1.14-1.87), family history of diabetes mellitus (OR1.38, CI-1.06-1.78), and cardiac disease (OR1.42, CI-1.18-1.65). Stroke severity was higher among those with METS (SLS = 5.8 ± 4.3) compared with those without METS (6.2 ± 4.5) at p = 0.037. METS was associated with higher odds (aOR 1.31, CI-1.08-1.58) of one-month fatality after adjusting for stroke severity, age > 50 years, and average monthly income >100USD.

CONCLUSION

METS is very common among African stroke patients and is associated with stroke severity and worse one-month fatality. Lifestyle interventions may prevent METS and attenuate its impact on stroke occurrence and outcomes.

Metabolic and Obesity Phenotype Trajectories in Taiwanese Medical Personnel

The distribution of metabolic and obesity phenotypes in Taiwanese medical personnel is unknown. In this study, trajectory analysis with repeated measurements was used to explore the development and associated risk factors of different metabolic and obesity phenotypes in hospital staff from a Taiwanese medical center. The results demonstrated that metabolically unhealthy workers presented with a higher body mass index (BMI) compared with their metabolically healthy counterparts. Male and aged > 40 years hospital workers were more likely to be in a deleterious metabolic/obesity state. Meanwhile, profession and working hours were not significantly associated with the development of certain phenotypes in our study. These results shed light on the necessity of adequate data retrieval regarding working hours, and a nuanced examination of working conditions among different professions. Our findings are helpful for the development of advanced guidance regarding health promotion in hospital workers.

Body impedance analyzer and anthropometric indicators; predictors of metabolic syndrome

Aim

Metabolic syndrome is one of the outcomes of a sedentary lifestyle in the modern world. In this study, we want to introduce the predictors of metabolic syndrome using anthropometric indices and Bio-Electrical Impedance Analysis (BIA) test values.

Method

This cross-sectional study was performed on 2284 employees of Tehran University of Medical Sciences in different job categories. Metabolic syndrome was determined according to IDF criteria. Anthropometric dimensions, para-clinical tests, basic information were collected from the participants. Also, the body analysis of the participants was performed using a BIA method.

Result

The prevalence of metabolic syndrome in this study was 23.2% based on IDF criteria, which was 21% and 26.6% in men and women, respectively. The most important factor among the components of IDF criteria was HDL deficiency. In this study, neck circumference, fat mass, visceral fat, muscle mass percentage and waist to height ratio were observed as predictors of metabolic syndrome.

Conclusion

This study realized that there is association between fat mass, fat-free mass, visceral fat and muscle mass which all are some elements of body composition analysis and metabolic syndrome as a major health issue.

Association of Age and Sex with Metabolic Syndrome in Taiwanese Adults

Objective

This study aimed to investigate the association of age and sex with metabolic syndrome (MS) in Taiwanese adults.

Methods

We extracted information of 4307 men and 4783 women aged 30–70 from the Taiwan Biobank.

Results

The interaction between age and sex on MS was significant (p-value = 0.0001). After stratification by sex, men and women aged 50–70 years (reference: 30≤age<50 years) had a higher risk of MS. The odds ratio (OR), 95% confidence interval (CI) was 2.316, 1.936–2.772 in men and 3.101, 2.561–3.754 in women. After stratification by age, men aged 50–70 years had a lower risk of MS compared to women (OR, 95% CI = 0.713, 0.598–0.851).

Conclusion

The interaction between age and sex on MS was significant. Sex-wise, both men and women aged 50–70 years had a higher likelihood of MS. Age-wise, men aged 50–70 years had a lower risk of MS compared to women.

Spousal Concordance in Dietary Behaviors and Metabolic Components, and Their Association: A Cross-Sectional Study

This study aims to investigate spousal concordance in dietary behaviors, spousal concordance in metabolic components (MCs), and their association. A cross-sectional survey was conducted in Taiwan from November 2014 to May 2015. Matched-pair analysis, McNemar’s test, logistic regression analysis, and stratified analysis were performed. A total of 901 pairs of spouses (1802 participants) were analyzed. Husbands were less likely to report intakes of high-fiber food (OR_MP (matched pairs odds ratio) = 0.30, p < 0.0001), fish (OR_MP = 0.74, p = 0.0128), biscuits or cakes (OR_MP = 0.60, p < 0.0001), and fast food (OR_MP = 0.65, p = 0.01) compared with their wives. Husbands had significantly higher odds of being overweight (OR_MP = 2.34, p < 0.0001); and of having hypertension (OR_MP = 2.14, p < 0.0001), hypercholesterolemia (OR_MP = 1.75, p = 0.0007), hyperlipidemia (OR_MP = 2.96, p < 0.0001), and one or more metabolic components (composite MCs) (OR_MP = 2.50, p < 0.0001) compared with their wives. After adjusting for age and education, the spousal concordance in high-fiber food intake was inversely associated with the spousal concordance in composite MCs (aOR = 0.62, 95% CI = 0.44–0.88, p = 0.0074), whereas the spousal concordance in processed food intake was positively associated with the concordance in composite MCs (aOR (adjusted odds ratio) = 1.56, 95% CI (Confidence Interval) = 1.03–2.36, p = 0.034). An intervention study for couples with intakes of different fiber foods and/or processed foods is critical for future study, in order to test what kinds of fiber foods/processed foods are associated with the development of the spousal concordance of metabolic components.

Prevalence of metabolic syndrome and its determinants among Iranian adults: evidence of IraPEN survey on a bi-ethnic population

Metabolic syndrome (MetS) is a growing public health concern worldwide. It has been demonstrated that individuals with MetS are at an increased risk of cardiovascular events and diabetes. We aimed to investigate the prevalence of MetS and its components among Turkic and Kurds ethnic groups in a bi-ethnic (Turk and Kurd) population. This cross-sectional study is part of the national health transformation plan created in response to the emerging epidemic of non-communicable diseases (Iran’s Package of Essential Non-communicable Disease study), launched in 2014 in Naqadeh, Iran. In total, 3506 participants aged 30–70 years were randomly included in the study from urban and rural regions. Cardio-metabolic risk factors related to MetS diagnosis and other related sociodemographic factors were assessed for men and women in both the Turk and the Kurd population. Multivariate logistic regressions were applied to identify MetS -associated factors among both the Turk and the Kurd population. The mean (SD) age of the participants was 49.6 (12.3) years. Of the participants, 56.2% (n = 1969) were women, and 43.8% (n = 1537) were men. Three-fifths of the participants were Turk (60.3%, n = 1751). The overall prevalence of MetS was 37.05%, with a higher prevalence in women (49.8% versus 24.3% in men). The prevalence of MetS and its components among Turk people (41.6%) were significantly higher than that among Kurd people (33.9%) (p < 0.0001). In addition, the prevalence of MetS was higher among women, urban, and older people for both ethnicities. Strong associations were found between MetS prevalence and being older, being female, being overweight, being obese, having a higher waist-to-hip ratio, and having a history of diabetes and cardiovascular disease (CVD) in the family for both Turks and Kurds. The raised waist circumference (WC) is the most prevalent MetS component for Turk men and women. Meanwhile, the most prevalent MetS component for Kurd participants is low high-density lipoprotein for women and a raised WC for men. Significant differences were found between Kurdish men and women for all components, except for a raised WC and a raised fasting blood glucose (p < 0.05). Because the Iranian population features multiple ethnicities, the recognition of the prevalence of MetS components is a major step in establishing intervention strategies for modifying cardio-metabolic risk factors based on the population ethnicities and their socio-demographic, cultural, and lifestyle factors. We recommend future studies for planning an efficient and sustainable health education and promotion program to halt MetS prevalence.

Dietary Total Antioxidant Capacity and Dietary Polyphenol Intake and Prevalence of Metabolic Syndrome in Polish Adults: A Nationwide Study

Specific classes and subclasses of polyphenols have been studied for their potential effects on noncommunicable diseases, but studies on association between dietary polyphenol intake (DPI) and dietary total antioxidant capacity (DTAC) and MetS (metabolic syndrome) are scarce. Therefore, the aim of this study was to determine associations between DTAC and DPI and the prevalence of MetS and its components in the Polish adult population. Subjects (5690) were participants of the Polish National Multicentre Health Examination Survey (WOBASZ II study) performed in 2013-2014. MetS was defined according to the International Diabetes Federation (IDF) and the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) criteria. Daily food consumption was assessed by 24-hour dietary recall. DTAC and DPI were evaluated using the data of food consumption and antioxidant potential of foods, measured by FRAP (ferric reducing antioxidant potential) method, and total polyphenol content in foods, measured by Folin-Ciocalteu assay. Logistic regression models were used to assess the relationship between DTAC and DPI and MetS and its components. Crude, age-adjusted, and multivariable-adjusted models were performed. This study demonstrated that in Polish women, high DPI and high DTAC were significantly associated with a reduced odds ratio for the prevalence of MetS components, such as elevated blood pressure and diabetes. In contrast, in men, high DPI and high DTAC did not have the potential to alleviate MetS components.

Impact of gender and menopausal status on metabolic parameters in chronic hepatitis C infection

Hepatitis C infection (HCV) and menopause are associated with insulin resistance (IR), and IR accelerates HCV-induced liver disease. The relationship between menopause and IR has not been studied in this population. This study aimed to assess the impact of menopause on IR and metabolic syndrome in HCV. One hundred and three (69 men, 16 premenopausal, 18 postmenopausal women) noncirrhotic, nondiabetic HCV-infected adults underwent IR measurement via steady-state plasma glucose during a 240-min insulin suppression test. Metabolic syndrome was defined by at least three of five standard laboratory/clinical criteria. The patient characteristics were as follows: mean age 48 years, waist circumference 94.4 ± 12.4 cm and 37.9% Caucasian. SSPG was higher in postmenopausal than premenopausal women or men (mean difference 18, 95% CI -41 to 76 and 35, 95% CI -3 to 72 mg/dL; respectively). After adjusting for waist circumference, female gender, nonwhite race and triglycerides were positively associated and high-density lipoprotein negatively associated with steady-state plasma glucose. Compared to men, both pre- (Coef 48, 95% CI 12-84) and postmenopausal women (Coef 49, 95% CI 17-82) had higher steady-state plasma glucose. Compared to premenopausal women, men (OR 2.0, 95% CI 0.38-10.2) and postmenopausal women (OR 2.9, 95% CI 0.46-18.8) had higher odds of metabolic syndrome, but this was statistically nonsignificant. Both liver inflammation (OR 7.9) and nonwhite race (OR 6.9) were associated with metabolic syndrome. We conclude that women are at inc-reased risk for IR in HCV. There may also be an increased risk of metabolic syndrome postmenopause. Along with lifestyle modification and weight loss, women with metabolic abnormalities represent an especially at-risk group warranting HCV treatment to prevent adverse metabolic outcomes.

Hemoglobin and Ferritin Concentrations in Subjects with Metabolic Syndrome

BACKGROUND

Metabolic syndrome (MetS), a clinical condition characterized by insulin resistance, glucose intolerance, dyslipidemia, hypertension, and obesity, has been linked with raised levels of serum ferritin (Sfr) concentrations.

OBJECTIVES

This study was carried out to compare hemoglobin (Hb) and Sfr concentrations in patients with MetS, regular donors and first-time donors.

MATERIALS AND METHODS

A total of 102 subjects who were between 18 and 60 years were enrolled for the study. They were divided into three groups. The first group (n = 20) was made up of 5 males and 15 females, all who met the criteria that define MetS. The second group (n = 52; M = 34, F = 18) were regular donors, while the last group (n = 30; M = 16, F = 14) were first-time donors or those who had not donated before. Following an overnight fast, 20 mL of venous blood was drawn from each subject. About 5 mL of this was put into sodium ethylenediaminetetraacetate (EDTA) specimen bottles for the full blood count parameters with Sysmex KX-21N hematology analyzer (made in Japan). The remaining 15 mL had serum separated for Sfr assay using enzyme-linked immunosorbent assay (ELISA) with a commercial assay kit manufactured by Teco Diagnostics.

RESULTS

Significant difference was found in the mean Sfr concentration of subjects with MetS (163 ± 136.92 ng/mL) and regular donors (41.46 ± 40.33 ng/mL), P = 0.001. The mean Sfr concentrations of subjects with MetS (163 ± 136.92 ng/mL) were also higher than that of first-time donors (102.46 ± 80.26 ng/mL), but it was not statistically significant, P = 0.053. The Hb concentrations of the three groups were not significantly different.

CONCLUSION

Sfr concentrations of regular donors were lower than that of subjects with MetS and first-time donors. The difference between regular donors and subjects with MetS was statistically significant. However, there is no significant difference in the Hb concentrations in the three groups. MetS is not associated with anemia or hyperferritinemia.

Metabolic syndrome in patients undergoing coronary angiography

INTRODUCTION

Metabolic Syndrome (MetS) is basically a cluster of cardiovascular risks that involve changes in metabolic and hemodynamic indicators; various organizations have defined it with small differences. Metabolic syndrome is a lethal endocrinopathy starting with insulin resistance and inviting a chain of systemic disorders such as abdominal obesity, glucose intolerance or diabetes mellitus (DM), dyslipidemia, hypertension (HT) and coronary artery disease (CAD).

MATERIAL AND METHODS

This prospective and descriptive study was conducted at the Cardiology Clinic of a Private Hospital in Osmaniye between January 2014 and May 2014. The study population included all patients who were administered a CA procedure at the Cardiology Clinic of Private New Life Hospital in Osmaniye in 2014.

RESULTS

The majority of the patients were male (63.3%), the mean age was 59.09±10.98, vast majority of them had social security (98.5%), 32.8% of them smoked, 7.2% had peripheral arterial disease (PAD), 52.5% were diagnosed with DM, 24.8% with HT, percutaneous transluminal coronary angioplasty (PTCA) or stent was administered to 40.3% of the patients who underwent CA and coronary artery bypass grafting (CABG) was decided for 15.5% of them. 41.8% of the patients met the MetS diagnosis criteria. The mean BMI was found to be 28.61±4.68, the mean FBS to be 143.20±74.83, the mean triglyceride value to be 168.73±96.94 and the mean HDL value to be 37.04±9.20. Although male gender came first among the patients who underwent CA, the prevalence of MetS did not show a statistically significant correlation with gender, mean age or smoking. The prevalence of HT, PAD and DM was significantly higher in the patients who met the MetS criteria. The mean values of FBS, HDL, CK-MB, triglyceride and cholesterol were also significantly higher in the patients who met the MetS criteria. As BMI increased, the rate at which MetS criteria are met also increased.

CONCLUSION

The objective is to prevent diabetes and cardiovascular diseases. Weight loss achieved with proper nutrition and an exercise program will have a reversing effect on all the disorders seen in metabolic syndrome.

Prevalence of metabolic syndrome: association with risk factors and cardiovascular complications in an urban population

Introduction

Metabolic syndrome (MS) is a set of cardiovascular risk factors and type 2 diabetes, responsible for a 2.5-fold increased cardiovascular mortality and a 5-fold higher risk of developing diabetes.

Objectives

1-to evaluate the prevalence of MS in individuals over 18 years associated with age, gender, socioeconomic status, educational levels, body mass index (BMI), HOMA index and physical activity; moreover, to compare it to other studies; 2-to compare the prevalence of elevated blood pressure (BP), high triglycerides and plasma glucose levels, low HDL cholesterol and high waist circumference among individuals with MS also according to gender; 3-to determine the number of risk factors in subjects with MS and prevalence of complications in individuals with and without MS aged over 40 years.

Methods

A cross-sectional study of 1369 Individuals, 667 males (48.7%) and 702 females (51.3%) was considered to evaluate the prevalence of MS and associated factors in the population.

Results

The study showed that 22.7% (95% CI: 19.4% to 26.0%) of the population has MS, which increases with age, higher BMI and sedentary lifestyle. There was no significant difference between genders until age ≥70 years and social classes. Higher prevalence of MS was observed in lower educational levels and higher prevalence of HOMA positive among individuals with MS. The most prevalent risk factors were elevated blood pressure (85%), low HDL cholesterol (83.1%) and increased waist circumference (82.5%). The prevalence of elevated BP, low HDL cholesterol and plasma glucose levels did not show significant difference between genders. Individuals with MS had higher risk of cardiovascular complications over 40 years.

Conclusion

The prevalence of MS found is similar to that in developed countries, being influenced by age, body mass index, educational levels, physical activity, and leading to a higher prevalence of cardiovascular complications after the 4th decade of life.

Decreased global DNA methylation in the white blood cells of high fat diet fed vervet monkeys (Chlorocebus aethiops)

Epigenetic mechanisms are associated with the development of many chronic diseases and due to their reversible nature offer a unique window of opportunity to reverse the disease phenotype. This study investigated whether global DNA methylation correlates with dysglycemia in the vervet monkey (Chlorocebus aethiops). Diet-induced changes in DNA methylation were observed where global DNA methylation was twofold lower in monkeys fed a high fat diet (n = 10) compared to monkeys fed a standard diet (n = 15). An inverse correlation was observed between DNA methylation, blood glucose concentrations, bodyweight, and age, although the association was not statistically significant. Consumption of a high fat diet is associated with the development of metabolic disease; thus, these results suggest the use of global DNA methylation as a biomarker to assess the risk for metabolic disease. Moreover, this study provides further support for the use of the vervet monkey as a model system to study metabolic diseases such as type 2 diabetes. Integration of altered DNA methylation profiles into predictive models could facilitate risk stratification and enable intervention strategies to inhibit disease progression. Such interventions could include lifestyle modifications, for example, the increased consumption of functional foods with the capacity to modulate DNA methylation, thus potentially reversing the disease phenotype and preventing disease.

Adherence to the Nordic Nutrition Recommendations in a Nordic population with metabolic syndrome: high salt consumption and low dietary fibre intake (The SYSDIET study)

BACKGROUND

The Nordic countries collaborate in setting recommendations for intake of nutrients by publishing the Nordic Nutrition Recommendations (NNR). Studies exploring how well the Nordic population adheres to the NNR are limited and none are available for the metabolic syndrome (MetS) subgroup. Individuals with MetS are a large part of the adult Nordic population and their diet's nutritional quality is of great importance as it can affect the progression of MetS.

OBJECTIVE

To evaluate nutritional intake in a cohort of Nordic adults with MetS or MetS risk factors and their adherence to the NNR.

DESIGN

A multi-centre study was carried out in six centres in four Nordic countries (SYSDIET CoE). Participants (n=175) were 30-65 years of age, with BMI 27-38 kg/m(2) and had at least two criteria for MetS. The NNR was used to evaluate the baseline nutrient intake calculated from the participants' 4-day food diaries using national nutrient databases.

RESULTS

Less than 20% of participants consumed ≤10 E% from saturated fat as recommended in the NNR. Recommended intake (RI) of polyunsaturated fat was met by approximately one-third of participants. Only 20% of men and 26% of women met the RI of dietary fibre. Intake below the defined lower intake level of 2.5 µg/day for vitamin D was observed in nearly 20% of participants. The daily median intake of salt was 8.8 g for men and 6.7 g for women.

CONCLUSION

Dietary quality of this Nordic population with Mets or MetS risk factors is unsatisfactory and characterised by high intakes of SFA and sodium and low intakes of PUFA and dietary fibre. Vitamin D intake was below RI level in a large part of the population. Authorities in the Nordic countries are encouraged to develop intervention programmes for high-risk groups.
