Conjoint Associations of Adherence to Physical Activity and Dietary Guidelines With Cardiometabolic Health: The Framingham Heart Study.

Background The conjoint associations of adherence to the recent physical activity and dietary guidelines with the metabolic syndrome (MetS) are incompletely understood. Methods and Results We evaluated 2379 FHS (Framingham Heart Study) Third Generation participants (mean age, 47 years; 54.4% women) attending examination cycle 2. We examined the cross-sectional relations of adherence to the 2018 Physical Activity Guidelines for Americans (binary; moderate-to-vigorous physical activity ≥150 versus <150 min/wk) and 2015 Dietary Guidelines for Americans (binary; 2015 Dietary Guidelines for Americans Adherence Index ≥median versus

Metabolic Syndrome in Children and Adolescents: Diagnostic Criteria, Therapeutic Options and Perspectives.

PURPOSE OF REVIEW: This review summarizes our current understanding of the metabolic syndrome (MetS) in children and adolescents. Special emphasis is given towards diagnostic criteria and therapeutic options. RECENT FINDINGS: Consistent diagnostic criteria to define MetS in childhood and adolescence are not available to date. There is common agreement that the main features defining MetS include (1) disturbed glucose metabolism, (2) arterial hypertension, (3) dyslipidemia, and (4) abdominal obesity. However, settings of cut-off values are still heterogeneous in the pediatric population. Additional features that may define cardiometabolic risk, such as non-alcoholic fatty liver disease (NAFDL) or hyperuricemia, are not considered to date. Prevalence of childhood obesity has more than doubled since 1980, and 6-39% of obese children and adolescents already present with MetS, depending on the definition applied. There is common agreement that a consistent definition of MetS is urgently needed for children to identify those at risk as early as possible. Such definition criteria should consider age, gender, pubertal stage, or ethnicity. Additional features such as NAFDL or hyperuricemia should also be included in MetS criteria. Lifestyle modification is still the main basis to prevent or treat childhood obesity and MetS, as other therapeutic options (pharmacotherapy, bariatric surgery) are not available or not recommended for the majority of affected youngster.

[Evaluation of a program for management of metabolic syndrome in adults with overweight and obesity]. / Evaluación de un programa ministerial para manejo del síndrome metabólico en adultos con sobrepeso y obesidad.

BACKGROUND: The Chilean Ministry of Health developed a healthy lifestyles intervention directed to adults with overweight and cardiovascular risk factors, called "Program on Healthy Eating and Physical Activity" (PASAF). AIM: To evaluate the impact of PASAF on nutritional status and metabolic parameters. PATIENTS AND METHODS: We analyzed databases from three primary care centers belonging to a municipality of Metropolitan Santiago. We selected adults enrolled in the PASAF during three years (2007-2009). The program lasted four months and included an assessment of anthropometric and metabolic parameters at baseline and at the end, eight workshops with a nutritionist, seven with a psychologist and 32 sessions of physical activity. RESULT: We evaluated 526 subjects aged ≥18 years (93% females), of whom 85.6% attended the last appointment for assessment. Analyzing available data, attendance to workshops was <50% of the scheduled sessions. Weight, body mass index and waist circumference decreased significantly (median: -1.4 kg, -0.6 kg/m² and -3 cm, respectively). The median weight loss was 1.8% of initial weight and 17.1% of participants experienced a decrease ≥5% of their initial weight. There were significant improvements in lipid levels and blood pressure among participants with lower initial excess weight. A reduction in fasting blood glucose was observed only among subjects who lost ≥5% of their initial weight. CONCLUSIONS: The PASAF modestly reduced nutritional parameters. Correction of metabolic parameters was especially effective in less obese subjects. The attendance to workshops was low.

[The efficacy of the combined rehabilitative treatment of the patients presenting with obesity, metabolic syndrome, and diseases of the hepatobiliary system].

A total of 80 patients presenting with exogenous constitutional obesity, metabolic syndrome, and diseases of the hepatobiliary system (including chronic non-calculous cholecystitis and fatty hepatosis) were enrolled to participate in the present study. The basal treatment consisted of the adequate reducing diet, remedial gymnastics, massage, reflexo-acupuncture, the application of galvanic muds, and controlled intake of chofitol. It was supplemented with magnetic laser irradiation of selected abdominal regions, and electrical stimulation of femoral, dorsal, and abdominal muscles. It was shown that the combination of the above procedures and physical factors significantly improves the overall outcome of the treatment. The patients suffering intestinal dysbacteriosis were prescribed the intake of probiotic Nor Narine together with Jermuk mineral water; they were found to benefit from such treatment due to normalization of intestinal biocenosis and improvement of their general condition. The clinical and paraclinical data obtained in this study give evidence of the therapeutic efficacy of certain physical factors and especially their combination used for the medical rehabilitation of the patients presenting with constitutional obesity, metabolic syndrome, and digestive disorders. Moreover, the well-apparent positive results were documented from the combined treatment with magnetic laser radiation and therapeutic muds.

[The combined rehabilitative treatment of the children with obesity and metabolic syndrome].

The present study included a total of 66 children at the age from 11 to 16 years with obesity and metabolic syndrome. The latter condition in the childhood and adolescence is characterized by the pronounced disturbances of basal metabolism, vasoactive systems, psychoemotional status, and regulatory hormonal functions that determine the choice of rehabilitative modalities. The combined treatment of such disturbances is considered to be an efficacious method for the rehabilitation of these patients. It is recommended that cortexin be prescribed to the children presenting with obesity and metabolic syndrome because this medication promotes correction of the hormonal and metabolic status and improves the brain cognitive function.

[Impact of a lifestyle intervention program on metabolic, anthropometrical and dietary profile of Japanese-Brazilians with and without metabolic syndrome]. / Impacto de um programa de intervenção sobre o estilo de vida nos perfis metabólico, antropométrico e dietético em nipo-brasileiros com e sem síndrome metabólica.

OBJECTIVE: We evaluated the changes in biochemical and nutritional profiles of Japanese-Brazilians with and without metabolic syndrome after two years of participation in the intervention program. MATERIALS AND METHODS: It was a non-controlled experimental study. The biochemical and clinical assessments were conducted at baseline (2005), after a year (2006) and after two years (2007) of intervention. On the present study, data of 360 individuals, who participated on the three assessments were considered. RESULTS: Both groups presented improvements on the anthropometric and metabolic profile, after two years of intervention. It was observed reduction in the intake of total fat, saturated fat, and dietary cholesterol, and increased intake of fiber among men without metabolic syndrome. It was observed reduction in the intake of total fat (p = 0,003) and monounsaturated fatty acid (p = 0,002). CONCLUSION: The results showed a positive impact of the lifestyle intervention program in metabolic and nutritional profile of Japanese-Brazilians with and without metabolic syndrome.

Exercise training improves in vivo endothelial repair capacity of early endothelial progenitor cells in subjects with metabolic syndrome.

BACKGROUND: Endothelial dysfunction and injury are considered to contribute considerably to the development and progression of atherosclerosis. It has been suggested that intense exercise training can increase the number and angiogenic properties of early endothelial progenitor cells (EPCs). However, whether exercise training stimulates the capacity of early EPCs to promote repair of endothelial damage and potential underlying mechanisms remain to be determined. The present study was designed to evaluate the effects of moderate exercise training on in vivo endothelial repair capacity of early EPCs, and their nitric oxide and superoxide production as characterized by electron spin resonance spectroscopy analysis in subjects with metabolic syndrome. METHODS AND RESULTS: Twenty-four subjects with metabolic syndrome were randomized to an 8 weeks exercise training or a control group. Superoxide production and nitric oxide (NO) availability of early EPCs were characterized by using electron spin resonance (ESR) spectroscopy analysis. In vivo endothelial repair capacity of EPCs was examined by transplantation into nude mice with defined carotid endothelial injury. Endothelium-dependent, flow-mediated vasodilation was analysed using high-resolution ultrasound. Importantly, exercise training resulted in a substantially improved in vivo endothelial repair capacity of early EPCs (24.0 vs 12.7%; p < 0.05) and improved endothelium-dependent vasodilation. Nitric oxide production of EPCs was substantially increased after exercise training, but not in the control group. Moreover, exercise training reduced superoxide production of EPCs, which was not observed in the control group. CONCLUSIONS: The present study suggests for the first time that moderate exercise training increases nitric oxide production of early endothelial progenitor cells and reduces their superoxide production. Importantly, this is associated with a marked beneficial effect on the in vivo endothelial repair capacity of early EPCs in subjects with metabolic syndrome.

Physical activity as the main therapeutic tool for metabolic syndrome in childhood.

Physical activity (PA) and diet directly influence obesity and metabolic syndrome (MS) as important determinants of body composition. Understanding how PA relates to MS in youth is of great importance, and could offer a common strategy for clinical and public health approaches to control this condition. The underlying disorder of MS is a condition of insulin resistance, and a strong relationship between PA level and insulin sensitivity is clearly ascertained. The type, duration, frequency and intensity of PA affect fuel metabolism, in particular carbohydrate and lipid oxidation. The possible modulation of metabolism because of increased fat oxidation by PA is the basis for both prevention and restoration of insulin resistance and MS in obese children. In daily clinical practice, diet followed by pharmacologic treatment are usually the approaches taken, whereas PA is often considered just a suggestion. Although diet and PA have different effects on body composition, with both contributing to fat loss, only PA increases muscle mass and thus has a direct effect on metabolic function, expressed by changes in cardiovascular risk factors. Therefore, it is important to remember their complementary but different targets in daily clinical practice, such as body weight control for diet and metabolic health for PA. In this review, we have summarized the literature on the relationship between PA and MS in pediatrics. Then, we have analyzed the possibility of using PA for MS treatment, as an alternative to drugs, by discussing the results of intervention studies, reasons for low compliance to PA, related benefits, adherence difficulties and costs. Finally, we have tried to suggest recommendations for a multiple-step PA strategy in children and adolescents at risk for MS, by considering PA as the 'key' player in treatment.

Management of the metabolic syndrome in patients with human immunodeficiency virus.

Patients with human immunodeficiency virus (HIV) are an increasing subpopulation of patients seen in endocrine/diabetes clinics. This article explores evidence-based treatment recommendations for patients with metabolic syndrome who are also positive for HIV. Patients infected with HIV may manifest metabolic abnormalities. They often present with low high-density lipoprotein (HDL-C), hypertension, visceral adiposity, and insulin resistance, among other symptoms consistent with features of the metabolic syndrome. The etiologies of the metabolic abnormalities are not completely understood. The role of highly active antiretroviral therapy (HAART) and the separate effect of HIV on patients who are surviving longer may contribute to the increased incidence of the development of the metabolic syndrome. The role of the health care team is to provide patient education to patients with HIV concerning lifestyle modification in order to prevent complications related to the metabolic syndrome.

Healthy lifestyle habits and 10-year cardiovascular risk in schizophrenia spectrum disorders: an analysis of the impact of smoking tobacco in the CLAMORS schizophrenia cohort.

AIM: We analysed the impact of tobacco smoking over several healthy lifestyle habits along with the impact on 10-years cardiovascular event (CVE) risk in the CLAMORS schizophrenia cohort. METHODS: This analysis was performed within the scope of the CLAMORS study which included consecutive outpatients meeting DSM-IV criteria for schizophrenia spectrum disorder. Beside smoking history, data on usual healthy lifestyle habits included current exercise, saturated fat sparing diet, low-caloric diet, and daily dietary fibre, salt, caffeine and alcohol consumption were recorded. The 10-year CVE risk was calculated with Framingham function. RESULTS: 1704 patients (61.1% male), 18 to 74 years were examined. Prevalence of smoking was 54.54% (95% CI: 52.16%-56.90%) significantly higher than in age and sex matched general population subjects, 31.51% (31.49%-31.52%); OR=2.61 (2.37-2.87, p<0.0001). After controlling by confounders smokers showed a 10-year CVE risk excess versus non-smokers of 2.63 (2.16-3.09), p<0.001. Smoking cessation would reduce the likely of high/very high 10-year CVE risk (above 10%) by near 90% [OR=0.10 (0.06-0.18), p<0.0001]. Also, smokers were more likely to consume alcohol daily [4.13 (3.07-5.54), p<0.0001] and caffeine [3.39 (2.72-4.23), p<0.0001] than non-smoker patients with schizophrenia, and less likely to avoid daily consumption of salt [0.58 (0.43-0.78), p<0.0001], saturated fat [0.71 (0.56-0.91), p=0.006], high fibre diet [0.67 (0.53-0.84), p=0.001], or to follow a low-caloric diet [0.63 (0.48-0.81), p<0.0001]. Smokers also were less likely to do exercise habitually [0.62 (0.48-0.82, p=0.001]. CONCLUSION: Compared with the general population, patients with schizophrenia showed significant higher prevalence of smoking. Smokers who stop smoking would benefit by a near 90% reduction in the likely of 10-year cardiovascular event risk above 10%.

Effects of a 6-month lifestyle modification intervention on the cardiometabolic risk factors and health-related qualities of life in women with metabolic syndrome.

Although therapeutic lifestyle modification (TLM) has been recommended as a cornerstone treatment of metabolic syndrome (MetS), little is known about the biobehavioral effects of a TLM program for patients in a community. The purpose of this study was to examine the effects of a 6-month TLM program on MetS risk factors and health-related qualities of life (HRQOL) among middle-aged and older women in a community in Korea. Fifty-two women (mean age, 62.7 +/- 9.0 years) with MetS were recruited from 3 community health centers and were randomly assigned to the intervention (n = 31) or control (n = 21) groups. The patients in the intervention group participated in supervised TLM sessions for 6 months. The TLM program included health monitoring, counseling, health education, exercise, and dieting. Metabolic risk factors and HRQOL were measured at baseline, during the study (month 3), at completion (month 6), and post completion (month 12) of the TLM program. Compared with the control group, the TLM group showed significantly greater reductions in body weight (P < .001) and waist circumference (P < .001); these effects were sustained for 6 months after intervention. With regard to HRQOL, the TLM group showed greater improvements in physical function (P = .017), general health (P < .001), vitality (P = .008), and mental health (P = .027). These improvements, however, were not sustained after the intervention. The results indicate that a nurse-led systematic TLM program may be an effective strategy for managing middle-aged and older women with MetS at a community level.

The influence of cardiac rehabilitation on inflammation and metabolic syndrome in women with coronary heart disease.

BACKGROUND: Metabolic syndrome (MetS) and increased inflammatory markers, both predictors of future cardiovascular events, are more prevalent in women with coronary heart disease (CHD). The influence of cardiac rehabilitation (CR) on MetS and inflammatory biomarkers is not well characterized for women. PURPOSE: : The purpose of this article was to examine the effects of a 12-week behaviorally enhanced CR exclusively for women compared with traditional CR on components of the MetS and inflammatory markers in women with CHD. METHODS: The randomized clinical trial used 2 treatment groups, both receiving a comprehensive 12-week CR program, with 1 group receiving a motivationally enhanced intervention exclusively for women. A subset of 91 women (mean age, 61.6 years) from the parent study provided serum samples to examine the effects of CR on high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and intercellular adhesion molecule-1 (ICAM-1). RESULTS: After CR, the total sample of women demonstrated significant reductions in hsCRP (P =.002), IL-6 (P <.001), TNF-alpha (P =.010), and ICAM-1 (P =.016). Women in the gender-tailored CR program significantly improved all biomarker levels compared with baseline (P <.05 for all), whereas those in the traditional group improved only hsCRP (P <.05) and IL-6 (P <.05) levels. The combined study group demonstrated improvements in several components of MetS (triglycerides, waist circumference, and systolic blood pressure) but not in others (high-density lipoprotein cholesterol, fasting glucose, and diastolic blood pressure). CONCLUSION: Cardiac rehabilitation promotes greater improvements in inflammatory biomarkers than in components of MetS for women with CHD. Improvements in body composition or weight may not be a precondition for the benefits of exercise because of loss of abdominal fat. Examining components of MetS as continuous variables is recommended to prevent lost information inherent in dichotomization.

Austrian Moderate Altitude Studies (AMAS): benefits of exposure to moderate altitudes (1,500-2,500 m).

OBJECTIVES: A considerable part of the millions of Alpine tourists suffer from pre-existing diseases (e.g., metabolic syndrome) and high daily stress levels. The main goal of the Austrian Moderate Altitude Study (AMAS) was to investigate (a) the consequences of an active vacation at moderate altitude on the key parameters of the metabolic syndrome (AMAS I) and (b) the effects of a short active vacation on adult progenitor cells, bio-psychological parameters, and heart rate variability (HRV). METHODS: During the AMAS I pilot study (n = 22; 1,700 m a.s.l.) and AMAS I main study (n = 71; 1,700 m a.s.l. and 200 m a.s.l.), the volunteers simulated 3-week coached hiking vacations. For AMAS II, healthy volunteers (n = 13) participated in a 1-week active holiday at 1,700 m. RESULTS: There were significant improvements of obesity, hypertension, dyslipidemia, and insulin resistance of AMAS I patients after the vacation. In AMAS II participants, we found an increase in circulating endothelial progenitor cells as well as improvements in bio-psychological and HRV parameters. CONCLUSIONS: Active vacations at moderate altitude are associated with a variety of positive health effects in persons with metabolic syndrome and in healthy subjects.

Effects of cardiac rehabilitation in patients with metabolic syndrome after coronary artery bypass grafting.

BACKGROUND: Cardiac rehabilitation (CR) has numerous beneficial effects, including the modification of coronary risk factors and improvement of the prognosis, in patients with coronary artery disease (CAD). Limited data are available regarding the effects of CR on the physical status and risk factors in patients with metabolic syndrome (MetS) after coronary artery bypass grafting (CABG). METHODS AND RESULTS: We enrolled 32 patients with MetS after CABG, who participated in a supervised CR program for 6 months. Metabolic parameters, blood chemistry, exercise tolerance, and muscle strength of the thigh were measured before and after CR. After CR: (1) the body mass index, waist circumference, and fat weight significantly decreased; (2) peak V O(2) and anaerobic threshold were significantly increased; (3) isokinetic peak torques of knee extensor and flexor muscles significantly increased; (4) metabolic scoring defined by the number of the modified Adult Treatment Panel criteria of the US National Cholesterol Education Program was significantly improved; (5) serum concentration of high-sensitivity C-reactive protein also significantly decreased. CONCLUSIONS: These results suggest that CR might be useful for patients with MetS after CABG.

Long-term cardiac rehabilitation and exercise training programs improve metabolic parameters in metabolic syndrome patients with and without coronary heart disease.

BACKGROUND AND AIMS: The effectiveness of long-term cardiac rehabilitation and exercise training programs on metabolic parameters was evaluated in metabolic syndrome subjects with and without coronary heart disease (CHD). METHODS AND RESULTS: Fifty-nine CHD and 81 non-coronary patients with metabolic syndrome (59+/-8 vs 56+/-9years) were identified retrospectively at entry into identical cardiac rehabilitation and exercise-training programs. Metabolic syndrome was defined using modified Adult Treatment Panel III criteria. Exercise training occurred approximately twice per week. Metabolic and exercise testing data were collected at baseline and after 12months during the course of the program. Mean duration of cardiac rehabilitation and exercise training programs was over one year in both coronary and non-coronary patients (366+/-111 vs 414+/-102days for CHD and non-coronary CHD cohorts respectively, p<0.01). Significant improvements in bodyweight, body mass index, blood lipids, triglyceride/HDL ratio and exercise tolerance were noted in both cohorts. At the end of follow-up, 31% of CHD and 20% of non-CHD subjects no longer possessed diagnostic criteria for metabolic syndrome (p<0.0001 and p<0.001 respectively). CONCLUSIONS: A long-term cardiac rehabilitation program reduces metabolic syndrome prevalence in CHD patients and results in a similar improvement in risk factor control for metabolic syndrome patients without CHD.

Dietary fat is associated with metabolic syndrome in Japanese Brazilians.

OBJECTIVE: The aim of this study was to examine the association of nutrient intakes with metabolic syndrome in a Japanese descendant population at high risk for metabolic abnormalities. RESEARCH DESIGN AND METHODS: In a population-based study of Japanese Brazilians aged > or =30 years, 412 men and 465 women were studied. The diagnosis of metabolic syndrome was based on the National Cholesterol Education Program criteria modified for Asians. Food intake was assessed by a validated food frequency questionnaire. RESULTS: Men and women showed similar mean ages (55.7 +/- 12.7 and 54.4 +/- 11.9 years) and 49% (95% CI 44.8-54.6) and 43% (38.4-47.6) had metabolic syndrome, respectively. As expected, clinical parameters were less favorable in the subset of subjects with metabolic syndrome. Men with metabolic syndrome showed higher cholesterol (233.2 +/- 116.3 vs. 211.7 +/- 5.8 g/day, P < 0.05) and lower carbohydrate (288.5 +/- 45.8 vs. 300.1 +/- 39.8 g/day, P < 0.001) intakes than those without metabolic syndrome, but no difference was observed among the women. After adjusting for sex, age, smoking, education level, generation, physical activity, total energy, and dietary fiber intake, a positive association between metabolic syndrome and total fat intake was detected. Comparing people in the highest quintile of total fat consumption with those in the lowest quintile, odds ratio (OR) of metabolic syndrome was 5.0 ([95% CI 1.58-16.00]; P < 0.005). In contrast, linoleic acid intake was inversely associated with metabolic syndrome (OR 0.50 [95% CI 0.26-0.98]; P < 0.05). Considering food groups, after adjustments only fried food intake was shown to be associated with increased risk of metabolic syndrome. CONCLUSIONS: Despite the limitation of such a study design in investigating cause-effect relationships, our findings favor the hypothesis that dietary total fat may increase whereas linoleic acid intake may reduce the risk of metabolic syndrome in Japanese descendants living in Brazil.

The incidence and persistence of the NCEP (National Cholesterol Education Program) metabolic syndrome. The French D.E.S.I.R. study.

CONTEXT: In 2001 the "National Cholesterol and Education Program Expert Panel" gave a clinical definition of the metabolic syndrome. The frequency of this syndrome at baseline and its incidence and persistence at three years is studied in a French population. SUBJECTS: 2109 men and 2184 women from the D.E.S.I.R. longitudinal cohort study (Data from an Epidemiological Study on the Insulin Resistance syndrome) in central-western France, aged 30 to 64 years, were examined at inclusion and three years later. METHODS: Evaluation of the frequencies, incidences and persistence of the metabolic syndrome and its abnormalities. This syndrome is defined by the presence of three or more of five abnormalities: waist circumference > 102/88 cm (men/women); triglycerides > o r=1.69 mmol/l, HDL-cholesterol<1.04/1.29 mmol/l (men/women); systolic/diastolic blood pressure > or =130 and/or 85 mmHg; fasting plasma glucose > or =6.1 mmol/l. RESULTS: At baseline, 10% of men and 7% of women had the metabolic syndrome. If the syndrome was defined to include a treatment in the abnormalities (for diabetes, hypertension, dyslipidemia), the syndrome frequencies increased to 16% and 11%. However only 12% and 8% respectively, had this syndrome both at inclusion and at three years. High blood pressure was the most frequent abnormality: 70% and 47% in men and women respectively, at inclusion. The most stable abnormality was high waist circumference (80% persisted), hyperglycaemia the least stable (60% persisted). Hyperinsulinaemia did not cluster closely with this syndrome. CONCLUSIONS: The age-specific frequency of the syndrome is more than 2.5 times higher in the US than in this French cohort and this ratio increased with age. The higher frequencies of abdominal obesity and low HDL-cholesterol in women than in men suggest that these gender-specific thresholds may need to be refined.
