1. The worldwide epidemic of obesity in adults has been mirrored in children in developed and developing countries. 2. Central obesity appears to be driving a cluster of abnormalities often referred to as the metabolic syndrome. 3. The definition of the metabolic syndrome in children is not suited to arbitrary cut-offs and a definition using the significant clustering of risk factors that is already evident in childhood and adolescent populations may be preferable. 4. An Australian population study showed that 25% of 8-year-olds and 29% of 14-year-olds could be described by the high risk cluster with features similar to adult metabolic syndrome. 5. The high risk cluster was significantly linked to high and low birthweight, shorter duration of breast-feeding, larger postnatal weight gains after 12 months of age and raised C-reactive protein, gamma glutamyl transferase and alanine transaminase levels. At-risk young adults have also been shown to have macroscopic atherosclerosis in post-mortem studies. 6. Identification of at-risk children has obvious benefits for the individual and as well, for prevention of a future cohort with raised cardiovascular morbidity and mortality; however, complexities and controversies exist in doing so. Familial, genetic and lifestyle risk factors aggregate and labelling children with predisease may be problematic. Committed political and societal changes are necessary to reduce childhood obesity and subsequent adult cardiovascular disease.

Both low back pain (LBP) and obesity are common public health problems, yet their relation remains controversial. The aim of this study was to investigate the associations between weight-related factors and the prevalence of LBP in young adults in Finland. Participants in the ongoing Cardiovascular Risk in Young Finns Study aged 24-39 years were included (N = 2,575). In 2001, 31.2% of men and 39.5% of women reported LBP with recovery within a month or recurrent or continuous pain during the preceding 12 months. For women only, those with higher body mass index, waist circumference, hip circumference, waist-to-hip ratio, serum leptin level, and C-reactive protein level showed an increased prevalence of LBP. With all weight-related factors in the model, only waist circumference was related to LBP in women. For women, the odds ratios of LBP were 1.2 (95% confidence interval: 0.8, 1.8) for a waist circumference of 80-87.9 cm and 1.8 (95% confidence interval: 1.0, 3.2) for a waist circumference of > or =88 cm compared with a waist circumference of <80 cm. This association was independent of C-reactive protein, leptin, and adiponectin levels. The authors' findings in a relatively young population suggest that abdominal obesity may increase the risk of LBP in women.

The aim of this work was to assess the 5-year incidence of hypertension and its predictors among prehypertensive adults. Under the context of the ATTICA Study, data from 1188 individuals, free of cardiovascular disease, but with defined high blood pressure levels (prehypertension) at baseline examination (during 2001-2002) were retrieved. In 2006, the 5-year follow-up of the study was performed, and 798 of the prehypertensive participants were allocated. In this work, incidence and determinants of developing hypertension were evaluated. The 5-year ageadjusted incidence of hypertension was 18.7% in men and 24.6% in women (P = 0.05); while almost one half of prehypertensive individuals at the age of 55-65 years developed hypertension, and approximately 6 out of 10 people over 65 years of age developed the disease. Multiple logistic regression analysis revealed that increased age (odds ratio [OR] per 1 year = 1.09, 95% confidence interval [CI] 1.07-1.12), male sex (OR = 0.40, 95% CI 0.21-0.68), high education status (OR per 1 year of school = 0.94, 95% CI 0.88-0.98), waist circumference (OR per 1 cm = 1.04, 95% CI 1.02-1.06) and C-reactive protein (OR per 1 mg/l = 1.12, 95% CI 1.05-1.20), were positively associated with the development of hypertension. Moreover, greater adherence to Mediterranean diet seems to protect only prehypertensive, with abdominal obesity patients prone to develop hypertension (OR = 0.94, 95% CI 0.90-0.98). Annual incidence of hypertension was roughly 4% in men and women. Older people, with low education, abdominal obesity, lower adherence to the Mediterranean diet, and increased inflammation, constitute a model of prehypertensive individuals that are prone to develop hypertension.

Hypertension is highly prevalent in South Africa, resulting in high stroke mortality rates. Since obesity is very common among South African women, it is likely that obesity contributes to the hypertension prevalence. The aims were to determine whether black African women have higher blood pressures (BPs) than Caucasian women, and whether obesity is related to their cardiovascular risk. African (N=102) and Caucasian (N=115) women, matched for age and body mass index, were included. Correlations between obesity (total body fat, abdominal obesity and peripheral fat) and cardiovascular risk markers (haemodynamic parameters, lipids, inflammatory markers, prothrombotic factors, adipokines, HOMA-IR (homoeostasis model assessment insulin resistance)) were compared between the ethnic groups (adjusted for age, smoking, alcohol and physical activity). Comparisons between low- and high-BP groups were also made for each ethnic group. Results showed that African women had higher BP (P<0.01) with increased peripheral vascular resistance. Surprisingly, African women showed significantly weaker correlations between obesity measures and cardiovascular risk markers when compared to Caucasian women (specifically systolic BP, arterial resistance, cardiac output, fibrinogen, plasminogen activator inhibitor-1, leptin and resistin). Interestingly, the latter risk markers were also not significantly different between low- and high-BP African groups. African women, however, presented significant correlations of obesity with triglycerides, C-reactive protein and HOMA that were comparable to the Caucasian women. Although urban African women have higher BP than Caucasians, their obesity levels are weakly related to traditional cardiovascular risk factors compared to Caucasian women. The results, however, suggest a link with the development of insulin resistance.

Severe or important blood pressure elevations are associated with the risk of cardiovascular disease. However, a significant proportion of myocardial infarctions and strokes occur in subjects with only slight elevations or even with normal blood pressure. Both the coexistence of other cardiovascular risk factors, such as diabetes or dyslipidemia, or those recently recognized, such as elevations of C-reactive protein or abdominal obesity and metabolic syndrome, or the presence of target organ damage, such as microalbuminuria, left ventricular hypertrophy, mild renal dysfunction or increased intima-media thickness, all indicate the existence of a high cardiovascular risk in mild hypertensives or in subjects with normal or high-normal blood pressure. Unfortunately, these high-risk patients are often not recognized and thus under-treated. The 2003 European Societies of Hypertension and Cardiology guidelines emphasize the importance of a complete risk assessment and stratification in subjects at all blood pressure categories. The search for other cardiovascular risk factors and target organ damage should be encouraged. Identification of these high-risk patients may allow an earlier indication for antihypertensive treatment and for correction of all cardiovascular risk factors. The objective would be to impair the progression or to induce the regression of silent vascular damage before a clinical event develops.

We report the determination of intramyocellular lipids (IMCLs) of the soleus muscle of patients with type 2 diabetes mellitus (T2DM) using proton magnetic resonance spectroscopy. In addition, the various anthropometric and biochemical profiles of these patients were determined, including estimation of C-reactive protein (CRP), an inflammatory marker of coronary heart disease, and insulin resistance [Homeostasis Model Assessment (HOMA-IR)]. The estimated CRP level and the IMCL content in these patients were correlated with body mass index, percentage of body fat, other measures of abdominal obesity, serum lipoproteins, fasting and post-oral glucose load serum insulin levels and other surrogate markers of insulin resistance. The IMCL content (P=.04), CRP (P=.008) and insulin resistance (P=.0007) were significantly higher in T2DM patients compared to healthy controls. However, IMCL content did not correlate with values of fasting insulin, HOMA-IR or CRP in either group. These findings have strong implications of increased cardiovascular risk in Asian Indians with T2DM. The absence of relationship between CRP and IMCL needs to be explored further in a study using a large sample size.

The aim of the current study was to examine the associations of visceral adiposity and exercise participation with C-reactive protein (CRP), insulin resistance, and endothelial dysfunction in Korean adults selected from the general population. We studied 160 Korean adults (aged 41.3 +/- 13.0 years; n = 38 men and n = 122 women) who volunteered in a health promotion program. Subjects were divided into 2 groups based upon spontaneous exercise participation for using a cross-sectional approach. We measured anthropometric factors (body mass index [BMI], percentage body fat, waist-hip ratio [WHR], and abdominal fat area by computed tomographic scanning), blood pressure (BP), blood levels of glucose, lipids, fibrinogen, CRP, leptin, hemoglobin A(1c), homeostasis model assessment (HOMA), and carotid intima media thickness (IMT; via ultrasonography). Associations among the variables were assessed by Pearson partial correlation and linear regression, controlling for age and sex. Independent t tests were used to assess differences between exercise participants and nonparticipants. Significance was accepted at P < .05. As expected, the measures of adiposity (BMI, percentage body fat, WHR, abdominal fat area) were highly correlated with each other (r = .49-.86, P < .01). Blood levels of high-sensitivity CRP (hsCRP), leptin, and HOMA were modestly correlated with all measures of adiposity. Visceral fat area was the most important predictor of hsCRP, explaining 19.6% of the variance using stepwise linear regression analysis (P < .01). As visceral fat area tertiles increased from low to high, a significant stepwise increment in blood levels of CRP (P < .001), HOMA (P = .005), and left carotid IMT (P = .035) was observed. However, hsCRP and HOMA were not significantly different when compared across whole-body fat tertiles. Systolic BP, diastolic BP, and left carotid IMT were modestly correlated with WHR and visceral fat area (P < .05); but systolic BP and diastolic BP were also correlated with BMI and percentage body fat (P < .05). Therefore, the relative importance of central adiposity as opposed to total body fatness in endothelial dysfunction is unclear. Compared with the nonexercise group, exercise participants had significantly lower (P < .05) WHR, visceral fat area, ratio of visceral fat area to subcutaneous area, hsCRP, hemoglobin A(1c), and HOMA, with no significant differences in BMI, percentage body fat, and physical fitness. Central obesity with high visceral fat is strongly associated with blood level of hsCRP, insulin resistance, and endothelial dysfunction-related factors in healthy Korean adults. In addition, exercise participation, even in the absence of difference in physical fitness, may be protective against development of central obesity and insulin resistance in this understudied Korean population.

Metabolic syndrome has been defined as the presence of abdominal obesity combined with 2 of the following factors: hypertension, dyslipidemia, and impaired glucose tolerance, or diabetes mellitus. Magnesium is an essential cofactor for more than 300 enzymes involved in carbohydrate and lipid metabolism. In this study, we enrolled 117 consecutive overweight and obese patients and we measured serum magnesium levels together with fasting serum glucose, high-density lipoprotein cholesterol, and triacylglycerols. A strong inverse relationship between magnesium levels in serum and the presence of metabolic syndrome was noticed. Moreover, magnesium levels decreased as the number of components of metabolic syndrome increased. Also, there is an inverse relationship between serum magnesium levels and high-sensitivity C-reactive protein. We concluded that decreased levels of serum magnesium are associated with increased risk for metabolic syndrome, perhaps by a low-grade inflammation process.

Central obesity in adulthood, the metabolic syndrome, erectile failure and lower urinary tract symptoms (LUTS) are all associated with lower-than-normal testosterone levels, although the relationship between testosterone and LUTS appears weak. The metabolic syndrome is associated with an overactivity of the autonomic nervous system. Alternatively, the metabolic syndrome is associated with markers of inflammation, such as C-reactive protein (CRP), maybe signalling intraprostatic inflammation. A large cohort of 95 middle-aged to elderly hypogonadal men (T levels 5.9-12.1 nmol l(-1)) were treated with parenteral testosterone undecanoate and its effects on the metabolic syndrome {waist circumference, cholesterol, CRP and LUTS [residual bladder volume (RBV), International Prostate Symptoms Score (IPSS), prostate volume, prostate-specific antigen (PSA)]} were evaluated. Along with the improvements of the metabolic syndrome, there was a significant decline of the values of the IPSS, RBV and CRP. There was a (low) level of correlation between the decline of waist circumference and residual volume of urine but not with IPSS and prostate size. Along with the improvement of the metabolic syndrome upon testosterone administration, there was also an improvement of the IPSS and of RBV of urine and CRP. The mechanism remains to be elucidated.

Abdominal obesity (high waist circumference) is more strongly associated with cardiovascular disease and type 2 diabetes than generalized adiposity (high body mass index). Recent research has highlighted the role of chronic overactivation of the endogenous endocannabinoid system, acting through its CB(1) receptor, as a key factor involved in the development of abdominal obesity and related cardiometabolic risk abnormalities such as insulin resistance, low HDL-cholesterol, hypertriglyceridemia, inflammation and low adiponectin. Evidence suggests that these cardiometabolic risk factors/markers are not optimally managed by current treatments. Improving the nutrition and physical activity/exercise habits of patients remains the cornerstone of management of elevated global cardiometabolic risk. Antagonism of the endocannabinoid system provides a novel strategy to target several unaddressed cardiometabolic risk markers/factors. Randomized trials of rimonabant in patients with overweight or obesity and/or type 2 diabetes have demonstrated marked and significant improvements in body weight, waist circumference, glycemic control (in patients with type 2 diabetes), features of atherogenic dyslipidemia, insulin resistance, adipose tissue-derived cytokines (leptin and adiponectin) and C-reactive protein (a marker of systemic inflammation). Further analyses suggested that about half of the improvements of several cardiometabolic risk markers were independent from concomitant weight loss. Blood pressure also improved with rimonabant treatment, this effect being consistent with the blood pressure lowering effect of weight loss. The tolerability and safety of rimonabant have been extensively studied and most transient side effects include some gastrointestinal side effects, anxiety, mood changes and incidence of depressive disorders, particularly in patients with previous history of depression. Rimonabant is a useful option for patients with abdominal obesity and with related cardiometabolic risk abnormalities such as an atherogenic dyslipidemia and/or type 2 diabetes.
