The metabolic syndrome consists of a combination of risk factors that include abdominal obesity, atherogenic dyslipidaemia, hypertension and insulin resistance. It increases the risk of cardiovascular disease and type 2 diabetes. The increased risk of cardiovascular disease is higher in women than in men. The first manifestation of metabolic syndrome may occur in pregnancy presenting as gestational diabetes or preeclampsia. Both conditions are associated with increased insulin resistance. Also metabolic syndrome is more common in polycystic ovarian syndrome. It has been suggested that there is a metabolic syndrome resulting from the menopause due to estrogen deficiency, as many of the risk factors are more prevalent in postmenopausal women. Also estrogen replacement improves insulin sensitivity and reduces the risk of diabetes. The key elements in managing the metabolic syndrome are weight reduction, increasing physical activity and diet modification. If blood pressure, lipid and glycaemic control are not achieved through these interventions then pharmacological therapy will be required.

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.

The mortality of schizophrenia patients is approximately twice that of the general population and there is a 20% reduction in life expectancy in this patient group. Cardiovascular disease (CVD) is responsible for as much as 50% of the excess mortality associated with schizophrenia. One important source of the high CVD prevalence is the cluster of metabolic characteristics defining the metabolic syndrome (MetS: 3 or more of the following features: abdominal obesity, high blood pressure, elevated levels of triglycerides and fasting glucose and low levels of high-density lipoproteins). Patients with schizophrenia seem to be undertreated for these vascular risk factors relative to the general population. More knowledge is needed concerning broadened risk factors of cardiovascular disease in a representative sample of schizophrenia patients. We conducted preliminary cross sectional analyses in a sample of 64 consecutive outpatients with schizophrenia with a mean age of 37 years consisting of 59% men, who were enrolled in a treatment study. All used antipsychotics, and 71% were smokers. We found that (percentage of patients under treatment for the respective somatic condition in parenthesis) 82% were overweight, 49% had hypertonia (17%), 24% hyperglycemia (3%), 48% hypertriglyceridemia and 13% hyperlipidemia (10% triglycerid or cholesterol lowering medication). Forty percent had metabolic syndrome compared to 11% in the normal population (Norway, age corrected). Additionally, estimates of insulin resistance will be conducted. We found that the prevalence of MetS components was high in outpatient schizophrenia. A substantial discrepancy was found between metabolic ill health and medication treatment of such conditions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The metabolic syndrome (MetS) is a common phenotype that is clinically defined by threshold values applied to measures of central obesity, dysglycemia, dyslipidemia, and/or elevated blood pressure, which must be present concurrently in any one of a variety of combinations. Insulin resistance, although not a defining component of the MetS, is nonetheless considered to be a core feature. MetS is important because it is rapidly growing in prevalence and is strongly related to the development of cardiovascular disease. To define etiology, pathogenesis and expression of MetS, we have studied patients, specifically Canadian families and communities. One example is familial partial lipodystrophy (FPLD), a rare monogenic form of insulin resistance caused by mutations in either LMNA, encoding nuclear lamin A/C (subtype FPLD2), or in PPARG, encoding peroxisomal proliferator-activated receptor-γ (subtype FPLD3). Because it evolves slowly and recapitulates key clinical and biochemical attributes, FPLD seems to be a useful monogenic model of MetS. A second example is the disparate MetS prevalence between two Canadian aboriginal groups that is mirrored by disparate prevalence of diabetes and cardiovascular disease. Careful phenotypic evaluation of such special cases of human MetS by using a wide range of diagnostic methods, an approach called “phenomics,” may help uncover early presymptomatic disease biomarkers, which in turn might reveal new pathways and targets for interventions for MetS, diabetes, and atherosclerosis.

In the present study, we examined the associations of total carbohydrate intake, dietary glycaemic load (DGL) and white rice intake with metabolic syndrome risk factors by sex in Korean adolescents. For the present cross-sectional study, data from the Fourth Korea National Health and Nutrition Examination Survey (2007–9) were used. A total of 2209 adolescents (n 1164 boys and n 1045 girls) aged 10–18 years with complete anthropometric, biochemical and dietary intake data were included in the study. Dietary intake data were obtained using the 24 h recall method, and total carbohydrate intake, DGL and white rice intake were divided into quartiles by sex. The metabolic syndrome and its risk factors were defined using the International Diabetes Federation criteria for children and adolescents. Fasting insulin levels and insulin resistance were included as the metabolic syndrome risk factors. All statistical analyses considered the complex sampling design effect and appropriate sampling weights. Multivariate linear regression analysis was used to estimate means with their standard errors of the mean for the metabolic syndrome risk factors across the quartiles of total carbohydrate intake, DGL and white rice intake. While high DGL was significantly associated with increased fasting glucose levels in boys, high total carbohydrate intake, DGL and white rice intake were consistently associated with reduced HDL-cholesterol levels in girls. High white rice intake was significantly associated with an increased risk of insulin resistance and the metabolic syndrome in girls but not in boys. Optimising dietary carbohydrate intake with respect to the source or amount is fundamental to preventing and managing metabolic diseases in Asian adolescents.
