ABSTRACT

The purpose of this study was to examine the prevalence of individual risk factors for metabolic syndrome as well as the prevalence of metabolic syndrome in the National Health and Nutrition Examination Survey (NHANES) 2003-2006.
The analytic sample consisted of 3,423 adults, 20 years of age and over, from NHANES 2003-2006. The National Cholesterol Education Program's Adult Treatment Panel III (NCEP/ATP III) guidelines were used to identify adults who met their criteria for metabolic syndrome. Prevalence estimates were calculated for each risk factor for metabolic syndrome in addition to the prevalence of metabolic syndrome. Prevalence estimates and odds ratios were analyzed by sex and by age group, race and ethnicity, and body mass index (BMI) stratified by sex.
Approximately 34% of adults met the criteria for metabolic syndrome. Males and females 40-59 years of age were about three times as likely as those 20-39 years of age to meet the criteria for metabolic syndrome. Males 60 years of age and over were more than four times as likely and females 60 years of age and over were more than six times as likely as the youngest age group to meet the criteria. Non-Hispanic black males were about one-half as likely as non-Hispanic white males to meet the criteria for metabolic syndrome, while non-Hispanic black and Mexican-American females were about 1.5 times as likely as non-Hispanic white females to meet the criteria. Overweight males were about six times as likely and obese males were about 32 times as likely as normal weight males to meet the criteria. Overweight females were more than five times as likely and obese females were more than 17 times as likely as normal weight females to meet the criteria.
These results demonstrate that metabolic syndrome is prevalent and that it increases with age and with BMI. The prevalence varied by race and ethnicity but the pattern was different for males and females.

    • "The prevalence of obesity, defined as having a body mass index (BMI) ≥ 30 kg/m 2 , has increased dramatically in recent decades in the United States, and more than 35% of adults and 20% of children are now obese [1]. Among obese individuals, approximately 65% of males and 56% of females meet the criteria for the metabolic syndrome, a state of metabolic dysregulation characterized by insulin resistance, hyperglycemia, dyslipidemias (particularly hypertriglyceridemia), and hypertension [2]. In obesity and/or metabolic syndrome, alterations also occur in circulating levels of insulin, bioavailable insulin-like growth factor (IGF)-1, adipokines (eg, leptin and adiponectin), inflammatory factors (eg, cytokines), and vascular integrity-related factors (eg, plasminogen activator inhibitor [PAI]-1 and vascular endothelial growth factor [VEGF]) [3] [4].

    ABSTRACT: Both black (B) and green (G) cardamom are used as flavours during food preparation. This study investigated the responses to B and G in a diet-induced rat model of human metabolic syndrome. Male Wistar rats were fed either a corn starch-rich diet (C) or a high-carbohydrate, high-fat diet with increased simple sugars along with saturated and trans fats (H) for 16 weeks. H rats showed signs of metabolic syndrome leading to visceral obesity with hypertension, glucose intolerance, cardiovascular remodelling and nonalcoholic fatty liver disease. Food was supplemented with 3% dried B or G for the final eight weeks only. The major volatile components were the closely related terpenes, 1,8-cineole in B and α-terpinyl acetate in G. HB (high-carbohydrate, high-fat + black cardamom) rats showed marked reversal of diet-induced changes, with decreased visceral adiposity, total body fat mass, systolic blood pressure and plasma triglycerides, and structure and function of the heart and liver. In contrast, HG (high-carbohydrate, high-fat + green cardamom) rats increased visceral adiposity and total body fat mass, and increased heart and liver damage, without consistent improvement in the signs of metabolic syndrome. These results suggest that black cardamom is more effective in reversing the signs of metabolic syndrome than green cardamom.

According to the National Health and Nutritional Examination Survey (NHANES) [4], the prevalence of metabolic syndrome among adults in the United States was approximately 23% from 1988 to 1994, but increased to almost 34% from 2003 to 2006 even though the criterion for fasting blood glucose was updated to 100 mg/dl [5].

    ABSTRACT: Aims To briefly summarize findings from epidemiological studies on the relationship between dairy product consumption and the metabolic syndrome(MetS). Materials and methods A search for relevant literature was undertaken on Web of Science, Google scholar, Pubmed (2000 to July 2013), to identify observational studies which examined the association between dairy intake and MetS (prevalence or incidence), and for any randomized controlled trials investigating the effect of dairy intake on MetS. Results Here we review the physiological effects and possible mechanisms involved of three main dairy constituents (calcium (Ca), protein, fat) on important components of the MetS. Effects of Ca may be related to intestinal binding to fatty acids or bile acids, or to changes in intracellular Ca metabolism by suppressing calciotropic hormones. Dietary proteins may increase satiety in both the short and longer term, which may result in a reduced energy intake. Dairy proteins are precursors of angiotensin-I converting enzyme-inhibitory peptides, which may lower blood pressure. To reduce the intake of saturated fatty acids (SFA), the consumption of low-fat instead of high-fat dairy products is recommended. Conclusion More research is warranted to better understand the physiological effects and the mechanisms involved of dairy products in the prevention and treatment of the MetS.
