ObjectiveHigh as well as low levels of IGF1 have been associated with cardiovascular diseases (CVD). The relationship of IGF1 with (components of) the metabolic syndrome could help to clarify this controversy. The aims of this study were: i) to investigate the association of IGF1 concentration with prevalent (components of) the metabolic syndrome; and ii) to examine the role of (components of) the metabolic syndrome in the relationship between IGF1 and incident CVD during 11 years of follow-up.MethodsData were used from the Longitudinal Aging Study Amsterdam, a cohort study in a representative sample of the Dutch older population (≥65 years). Data were available in 1258 subjects. Metabolic syndrome was determined using the definition of the US National Cholesterol Education Program Adult Treatment Panel III. CVD were ascertained by self-reports and mortality data.ResultsLevels of IGF1 in the fourth quintile were associated with prevalent metabolic syndrome compared with the lowest quintile (odds ratio: 1.59, 95% confidence interval (CI) 1.09–2.33). The middle up to the highest quintile of IGF1 was positively associated with high triglycerides in women. Metabolic syndrome was not a mediator in the U-shaped relationship of IGF1 with CVD. Both subjects without the metabolic syndrome and low IGF1 levels (hazard ratio (HR) 1.75, 95% CI 1.12–2.71) and subjects with the metabolic syndrome and high IGF1 levels (HR 2.28, 95% CI 1.21–4.28) demonstrated increased risks of CVD.ConclusionsIn older people, high-normal IGF1 levels are associated with prevalent metabolic syndrome and high triglycerides. Furthermore, this study suggests the presence of different pathomechanisms for both low and high IGF1 levels and incident CVD.

Introduction. Fasting glucose (FG) is part of the Adult Treatment Panel III (ATP III) criteria for defining the metabolic syndrome (MetS). Glycated hemoglobin (HbA1c) is a measure of 2-3 month endogenous glucose exposure and is now recommended for diabetes diagnosis and screening for high-risk individuals. The aim of this study was to evaluate if replacing FG with HbA1c to define MetS improves prediction of incident coronary heart disease (CHD) in the Atherosclerosis Risk in Communities (ARIC) cohort. Methods. We included 11,194 ARIC participants without diabetes (based on diagnosis, medication use, FG ≥126 mg/dL, or HbA1c ≥6.5%) or prevalent CHD at baseline (1990-92). Cox proportional hazards models (adjusted for age, race, and study center) were used to compare the association between MetS defined using HbA1c (5.7-6.4%) or FG (100-125 mg/dL, based on ATP III guidelines) and risk of CHD (defined by myocardial infarction or fatal CHD, event data available through 2009). Results. Study participants had a mean age at baseline of 57 years, 43% were male, and 79% were white; median follow-up time was 16 years. Thirty-four percent of the study population had both normal FG (<100 mg/dL) and HbA1c (<5.7%), 37% had elevated FG and normal HbA1c, 4% had normal FG and elevated HbA1c, and 25% had both elevated FG (100-125 mg/dL) and HbA1c (5.7-6.4%). The association of combined FG and HbA1c categories with incident CHD are shown in the Figure. The adjusted hazard ratio predicting for incident CHD from MetS status was 1.43 (95% CI: 1.25-1.63, c-statistic: 0.61) using FG in the definition of MetS and 1.69 (95% CI: 1.48-1.93, c-statistic: 0.62) in the model replacing FG with HbA1c. Conclusions. Incorporating HbA1c into the definition of the MetS may help in identifying individuals who should be targeted for aggressive CHD risk factor reduction. Additionally, HbA1c may be useful clinically and in research settings for identifying individuals with MetS in cases where FG measures are not available.

Abstract Metabolic syndrome is a term linking the clinical profiles of some of the world's major health problems today: obesity, heart disease, and diabetes. It is predicated on dietary patterns, and particularly on the delivery of fuel. The effects may be seen first in the development of abdominal obesity and insulin resistance leading to Type 2 diabetes mellitus and coronary heart disease. This review examines the role resistant starch might play in the prevention and management of these conditions. Beginning with a definition of resistant starch, a critical review of the scientific literature is presented. Current knowledge suggests that resistant starch in the diet may assist in the prevention and management of conditions associated with the metabolic syndrome via its potential effects on delaying the delivery of glucose as fuel with subsequent fat utilization and appetite control benefits. There is still a great deal of research to be undertaken in this area, but it is clearly warranted, given the position of starches in the global food supply and the potential impact on population health.

AbstractObjectiveTo analyse whether poor breakfast habits in adolescence predict the metabolic syndrome and its components in adulthood. Previous studies suggest that regular breakfast consumption improves metabolic parameters.DesignProspective. Breakfast habits and other lifestyle variables at age 16 years were assessed from questionnaires. Poor breakfast habits were defined as skipping breakfast or only drinking or eating something sweet. At age 43 years, the effective sample consisted of 889 participants defined as having the metabolic syndrome or not, using the International Diabetes Federation criteria. Logistic regression was used to calculate odds ratios and confidence intervals.SettingThe Northern Swedish Cohort, a longitudinal population-based cohort with 27-year follow-up.SubjectsAdolescents (age 16 years).ResultsPrevalence of the metabolic syndrome at age 43 years was 27·0 %. Of the participants, 9·9 % were classified with poor breakfast habits at age 16 years. Adjusted odds for the metabolic syndrome at age 43 years was OR = 1·68 (95 % CI 1·01, 2·78) for those with poor breakfast habits at age 16 years compared with breakfast eaters. Looking at the metabolic syndrome components, poor breakfast habits at age 16 years were associated with central obesity (OR = 1·71; 95 % CI 1·00, 2·92) and high fasting glucose (OR = 1·75; 95 % CI 1·01, 3·02) at age 43 years, even after multivariate adjustments.ConclusionsPoor breakfast habits in adolescence predicted the metabolic syndrome in adulthood. Of the metabolic syndrome components, poor breakfast habits in adolescence predicted central obesity and high fasting glucose in adulthood. Further research is needed to fully understand the relationship between early breakfast habits and adult metabolic syndrome.

The purpose of this study was to explore the relationship between the metabolic syndrome severity Z-score and kidney function by gender. We also examined the estimated glomerular filtration rate in relation to other known risk factors. The study used was a population-based prospective longitudinal research design. A total of 4,838 participants (2,683 females and 2,155 males) included individuals aged >30 years who were undergoing a health examination from 2006 to 2014 in Pingzhen City, Taiwan. In the initial generalized estimated equation model analysis, which included the covariates of age of first visit, period between the first and current visit, and metabolic syndrome severity Z-score, the results indicated that the interaction between age and metabolic syndrome severity Z-score is significantly related to the estimated glomerular filtration rate for males ( p = .040). For females, the interaction between age and metabolic syndrome severity Z-score was not significant, but a higher metabolic syndrome severity Z-score was significantly associated with lower estimated glomerular filtration rate ( p = .001). After controlling for the confounders, unhealthy behaviors, and comorbidities, the metabolic syndrome severity Z-score was still a negative predictor of estimated glomerular filtration rate in both the male ( p = .005) and female ( p = .023) models.
