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

It has been reported that the frequency of cola intake (COLA) is positively associated with serum triglycerides and negatively associated with high-density-lioprotein (HDL) cholesterol, both components of the metabolic syndrome (MetS). The question now is whether noncola soft drink intake (NCOLA) is associated with MetS. Among the 18 770 participants in the Oslo Health Study, 5373 men and 6181 women had data on COLA and NCOLA and risk factors for MetS (except fasting glucose). Main MetS requirements are central obesity and 2 of the following: increased triglycerides, low HDL cholesterol, increased systolic or diastolic blood pressure, and elevated fasting blood glucose. The MetSRisk index was calculated to estimate many MetS components. Using regression analyses, the association between COLA (NCOLA) and MetS (MetSRisk) was studied. In young (aged 30 years), middle-aged (aged 40 and 45 years), and senior (aged 59 and 60 years) men and women, there was, in general, a positive correlation between COLA and MetSRisk, and between COLA and single MetS risk factors, except HDL cholesterol, which was negatively correlated. A less consistent picture was found for NCOLA. By regression analyses, after adjustment for sex, age, time since last meal, and use of sugar-sweetened soft drinks, a positive association between COLA (NCOLA) and MetSRisk (MetS) was still found. However, when also controlling for cheese, fatty fish, coffee, alcohol, smoking, physical activity, education, and birthplace, only the association with COLA remained significant, irrespective of the presence or absence of sugar. In conclusion, the self-reported intake frequency of soft drinks can be positively associated with MetS.

Background: The prevalence of obesity, one risk factor for developing the metabolic syndrome (MS), has increased during the last decades. It has therefore been assumed that the prevalence of MS would also increase. Aims: The aim was to analyse the prevalence of MS and its risk factors in a middle-aged Swedish population. Methods: Data were obtained between 2003 and 2004 from a random population based sample of 502 men and 505 women, 45–69 years old. Measures of plasma glucose, serum lipids, blood pressure, weight, height, waist circumference and self-reported data concerning presence of disease, medication and lifestyle were obtained. Results: The prevalence of MS was 14.8% among men and 15.3% among women, with an increase by age among women only, 10% to 25% ( p = 0.029). Among individuals with MS the most frequent risk factor was large waist circumference, present in 85% of men and 99% of women, followed by high blood pressure, high triglycerides, high glucose and HDL cholesterol (38% and 47% respectively). Conclusion: The prevalence of MS was 15%, increasing with age only among women. Overweight was a dominant characteristic, and only half of the individuals with MS had glucose/HDL cholesterol levels beyond defined cut points of the syndrome.

A cluster of metabolic factors have been merged into an entity named the metabolic syndrome. Although the characteristics of this syndrome have varied over time the presently used definition was established in 2009. The presence of three abnormal findings out of five components qualifies a person for the metabolic syndrome: elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure and elevated fasting plasma glucose. Cut points have been defined for all components apart from waist circumference, for which national or regional values are used. The metabolic syndrome predicts cardiovascular disease and type 2 diabetes. This associated risk does not exceed its components whereof elevated blood pressure is the most frequent. A successful management should, however, address all factors involved. The management is always based on healthy lifestyle choices but has not infrequently to be supported by pharmacological treatment, especially blood pressure lowering drugs. The metabolic syndrome is a useful example of the importance of multiple targets for preventive interventions. To be successful management has to be individualized not the least when it comes to pharmacological therapy. Frail elderly people should not be over-treated. Knowledge transfer of how risk factors act should be accompanied by continuous trust building and motivation. In complex situations with a mix of biological risk factors, adverse social conditions and unhealthy lifestyle, everything cannot be changed at once. It is better to aim for small steps that are lasting than large, unsustainable steps with relapses to unhealthy behaviours. A person with the metabolic syndrome will always be afflicted by its components, which is the reason that management has to be sustained over a very long time. This review summarizes the knowledge on the metabolic syndrome and its management according to present state of the art.

The reversal rate from clustering of cardiovascular disease (CVD) risk factors—components of the metabolic syndrome (MetS) is not known.Methods and Results. Among 35,534 subjects who received the annual health examinations at the NiigataHealth Foundation (Niigata, Japan), 4,911 subjects had clustering of 3 or more of the following CVD risk factors: (1) body mass index (BMI) ≥25 Kg/m2, (2) blood pressure ≥130 mm Hg in systolic and/or ≥85 mm Hg in diastolic, (3) triglycerides ≥150 mg/dL, (4) high-density lipoprotein cholesterol ≤40 mg/dL in men, ≤50 mg/dL in women, and (5) fasting blood glucose ≥100 mg/dL. After 5 years 1,929 subjects had a reversal of clustering (39.4%). A reversal occurred more often in males. The subjects with a reversal of clustering had milder level of each risk factor and a smaller number of risk factors, while BMI was associated with the least chance of a reversal.Conclusion. We concluded that a reversal of clustering CVD risk factors is possible in 4/10 subjects over a 5-year period by habitual or medical interventions. Gender and each CVD risk factor affected the reversal rate adversely, and BMI was associated with the least chance of a reversal.

BackgroundDepression is associated with the metabolic syndrome (MS). We examined whether metabolic dysregulation predicted the 2-year course of clinical depression.MethodA total of 285 older persons (⩾60 years) suffering from depressive disorder according to DSM-IV-TR criteria was followed up for 2 years. Severity of depression was assessed with the Inventory of Depressive Symptomatology (IDS) at 6-month intervals. Metabolic syndrome was defined according the National Cholesterol Education Programme (NCEP-ATP III). We applied logistic regression and linear mixed models adjusted for age, sex, years of education, smoking, alcohol use, physical activity, somatic co-morbidity, cognitive functioning and drug use (antidepressants, anti-inflammatory drugs) and severity of depression at baseline.ResultsMS predicted non-remission at 2 years (odds ratioper component = 1.26, 95% confidence interval 1.00–1.58), p = 0.047), which was driven by the waist circumference and HDL cholesterol. MS was not associated with IDS sum score. Subsequent analyses on its subscales, however, identified an association with the somatic symptom subscale score over time (interaction time × somatic subscale, p = 0.005), driven by higher waist circumference and elevated fasting glucose level.ConclusionsMetabolic dysregulation predicts a poor course of late-life depression. This finding supports the concept of ‘metabolic depression’, recently proposed on population-based findings of a protracted course of depressive symptoms in the presence of metabolic dysregulation. Our findings seem to be driven by abdominal obesity (as indicated by the waist circumference) and HDL cholesterol dysregulation.

AbstractIrregularity in eating patterns could be a potential cardiometabolic risk factor. We aimed to study the associations of irregular intake of energy at meals in relation to cardiometabolic risk factors 10 and 17 years later. Variability of energy intake data – derived from 5-d estimated diet diaries of cohort members of the National Survey for Health and Development collected at ages 36 (n1416), 43 (n1505) and 53 years (n1381) – was used as a measure for irregularity. Associations between meal irregularity scores with cardiometabolic risk factors measured 10 and 17 years later were investigated using linear mixed models and logistic regression models. The results showed that irregularity scores changed significantly over the years (P<0·05). At age 36 years, subjects with a more irregular intake of energy at lunch (OR 1·42; 95 % CI 1·05, 1·91) and between meals (OR 1·35; 95 % CI 1·01, 1·82) had an increased risk for the metabolic syndrome 17 years later; at lunch was also associated with an increased waist circumference (OR 1·58; 95 % 1·27, 1·96) and TAG levels (OR 1·33; 95 % CI 1·02, 1·72). At age 43 years, subjects with a more irregular intake at breakfast had an increased risk of the metabolic syndrome 10 years later (OR 1·53; 95 % CI 1·15, 2·04), as well as an increased BMI (OR 1·66; 95 % CI 1·31, 2·10), waist circumference (OR 1·53; 95 % CI 1·23, 1·90) and diastolic blood pressure (OR 1·42; 95 % CI 1·13, 1·78). In conclusion, subjects with a more irregular intake of energy, mostly at breakfast and lunch, appeared to have an increased cardiometabolic risk 10 and 17 years later.

Background Prevalence of Metabolic syndrome is high among Asians including Indians, and is high among those having sedentary occupations. Teaching is one of the important occupations, which demands no strenuous physical activity. However, there is little information available about the prevalence of metabolic syndrome among teaching staff of engineering college. Hence, the present study was conducted to study its prevalence, certain risk factors and co-morbidities among teaching staff of engineering institutes. Methods Teachers from engineering colleges of Nagpur city were the study subjects. Data was collected by interview technique. Clinical examination and laboratory investigations like Fasting blood glucose, High Density Lipoproteins and Serum Triglycerides were done. National Cholesterol Evaluation Programme (NCEP) Adult Treatment Panel Three (ATPIII) criteria were used to study Metabolic syndrome. Blood pressure and anthropometric measurements like height, weight and waist circumference were obtained by standard methods. Results The prevalence of metabolic syndrome was found to be 20.5%. It was 25.32% in females and 19.31% in males. It was more common in subjects of higher age group, muslim religion, and among widows and separated. Alcohol consumption, smoking and sedentary life style was found to be significantly associated with presence of metabolic syndrome. Frozen shoulder, fungal infection and stroke were common co morbidities found among subjects having metabolic syndrome.

Background/Aim: Multiple risk factors including dysipidemia, hypertension and hyperglycemia which cluster together are termed the metabolic syndrome. It means managing the metabolic syndrome is crucial to prevent cardiovascular disease (CVD). Several studies found that CVD is the common disease and the leading cause of on-duty death among firefighters. Although importance of understanding to investigate risk factors that causes CVD among firefighter has been emphasized, research about it is still behind. Thus, to understand risk factor of CVD among firefighters, this study was examined an association between metabolic syndrome and shift work among firefighters. Methods: A total of 257 men firefighters were included from Firefighter Research Enhancement of Safety & Heath (FRESH) cohort in Korea. No history of CV related disease including hypertension and diabetes were selected. Weight circumference, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured. SBP and DBP were measured three times at interval of five minutes in resting and average of the three of SBP and DBP was used in this analysis. Fasting hyperglycaemia, Triglycerides and HDL cholesterol were analysed from blood sample collected from the participants. Metabolic syndrome, using the modified National Cholesterol Education Program (Adult Treatment Panel III) criteria, was defined. The information of shift works, smoking and alcohol consumption were self-reported from the participants and divided into three; no shift work, 24 hour shift work and 2 or 3 shifts works. To analysis the association between metabolic syndrome and shift works, logistic model was used, adjusting for age, BMI, smoking and alcohol. Results: 26 (10.1%) participants out of 257 were metabolic syndrome in the participants group. The unadjusted prevalence of the metabolic syndrome by shift works is 8.2% in no shift work group, 7.1% in 24 hour shift work group and 15.9% in 2 or 3 shifts work group. Adjusted Odds Ratio (OR) with 95% CI for 24 hours shift work was 1.51 [0.35 6.45] and 4.77 [1.08 20.9] for 3 shifts works. Conclusions: There is an association between metabolic syndrome and shift work in Korea firefighters, which implies shift work might be associated with CVD.

Background: The relative contribution of selected circulatory biomarkers that represent distinct biological pathways to the incidence of metabolic syndrome (MetS) in African Americans is not well elucidated despite the greater prevalence of cardiovascular diseases in this ethnic group. Thus, we aimed to assess the relative contribution of a panel of representative cardiometabolic biomarkers with the hypothesis that they are predictors of incident MetS and longitudinal changes in MetS components. Materials and Methods: At the end of the second JHS examination cycle (average 4.7 years from baseline), 178 participants of the total 1055 without prevalent MetS at baseline had developed MetS. We selected informative markers from a panel of 7 representing inflammation (C - reactive protein and leptin), neurohormonal activity (aldosterone, BNP, cortisol), and endothelial function (endothelin and homocysteine) that were significantly associated with incident metabolic syndrome (MetS). Biomarker selection was performed using stepwise selection in multivariable logistic regression models. We adjusted for baseline age, gender, systolic and diastolic BP, log triglycerides, fasting glucose and HDL cholesterol, and waist circumference measurements. Results: Serum homocysteine, aldosterone and B-natriuretic peptide (BNP) concentration were retained as significantly associated with incident MetS, with p-values 0.037, 0.008 and 0.022, respectively. The multivariable adjusted OR (95%CI) were 1.28 (1.02 to 1.62) for homocysteine; 1.33 (1.08 to 1.65) for aldosterone, and 2.47 (1.31 to 4.66) for 2nd BNP quartile compared to the first quartile. In multivariable analyses evaluating longitudinal change in MetS components (analyzed as continuous variables); homocysteine was significantly and positively associated with diastolic BP. Serum aldosterone was associated with all MetS risk factors, while higher levels of plasma circulating BNP were associated with all risk factors except sex-standardized waist circumference. Discussion and Conclusions: Higher circulating homocysteine and aldosterone levels were directly associated with the development of MetS and with longitudinal change of its components except HDL cholesterol and sex standardized waist circumference, which were negatively associated with aldosterone. The second and fourth quartiles of circulating plasma BNP concentration were significantly associated with greater odds of developing MetS than the first quartile. Further, higher concentration of BNP was associated with positive changes in all risk components except for HDL cholesterol and waist circumference. These results suggest that the biomarkers and their related pathways are essential in mediating metabolic risk in African Americans.

An increasing number of children are exhibiting features of the metabolic syndrome (MetS) including abdominal fatness, hypertension, adverse lipid profile and insulin resistance. Healthy eating practices during school hours may improve the cardiometabolic profile, but there is a lack of evidence. In the present study, the effect of provision of school meals rich in fish, vegetables and fibre on a MetS score (primary outcome) and on individual cardiometabolic markers and body composition (secondary outcomes) was investigated in 834 Danish school children. The study was carried out as a cluster-randomised, controlled, non-blinded, cross-over trial at nine schools. Children aged 8–11 years received freshly prepared school lunch and snacks or usual packed lunch from home (control) each for 3 months. Dietary intake, physical activity, cardiometabolic markers and body composition were measured at baseline and after each dietary period. The school meals did not affect the MetS score (P= 1·00). However, it was found that mean arterial pressure was reduced by 0·4 (95 % CI 0·0, 0·8) mmHg (P= 0·04), fasting total cholesterol concentrations by 0·05 (95 % CI 0·02, 0·08) mmol/l (P= 0·001), HDL-cholesterol concentrations by 0·02 (95 % CI 0·00, 0·03) mmol/l, TAG concentrations by 0·02 (95 % CI 0·00, 0·04) mmol/l (bothP< 0·05), and homeostasis model of assessment-insulin resistance by 0·10 (95 % CI 0·04, 0·16) points (P= 0·001) compared with the control diet in the intention-to-treat analyses. Waist circumference increased 0·5 (95 % CI 0·3, 0·7) cm (P< 0·001), but BMIz-score remained unaffected. Complete-case analyses and analyses adjusted for household educational level, pubertal status and physical activity confirmed the results. In conclusion, the school meals did not affect the MetS score in 8–11-year-olds, as small improvements in blood pressure, TAG concentrations and insulin resistance were counterbalanced by slight undesired effects on waist circumference and HDL-cholesterol concentrations.
