Multi-omics signatures in new-onset diabetes predict metabolic response to dietary inulin: findings from an observational study followed by an interventional trial.

AIM: The metabolic performance of the gut microbiota contributes to the onset of type 2 diabetes. However, targeted dietary interventions are limited by the highly variable inter-individual response. We hypothesized (1) that the composition of the complex gut microbiome and metabolome (MIME) differ across metabolic spectra (lean-obese-diabetes); (2) that specific MIME patterns could explain the differential responses to dietary inulin; and (3) that the response can be predicted based on baseline MIME signature and clinical characteristics. METHOD: Forty-nine patients with newly diagnosed pre/diabetes (DM), 66 metabolically healthy overweight/obese (OB), and 32 healthy lean (LH) volunteers were compared in a cross-sectional case-control study integrating clinical variables, dietary intake, gut microbiome, and fecal/serum metabolomes (16 S rRNA sequencing, metabolomics profiling). Subsequently, 27 DM were recruited for a predictive study: 3 months of dietary inulin (10 g/day) intervention. RESULTS: MIME composition was different between groups. While the DM and LH groups represented opposite poles of the abundance spectrum, OB was closer to DM. Inulin supplementation was associated with an overall improvement in glycemic indices, though the response was very variable, with a shift in microbiome composition toward a more favorable profile and increased serum butyric and propionic acid concentrations. The improved glycemic outcomes of inulin treatment were dependent on better baseline glycemic status and variables related to the gut microbiota, including the abundance of certain bacterial taxa (i.e., Blautia, Eubacterium halii group, Lachnoclostridium, Ruminiclostridium, Dialister, or Phascolarctobacterium), serum concentrations of branched-chain amino acid derivatives and asparagine, and fecal concentrations of indole and several other volatile organic compounds. CONCLUSION: We demonstrated that obesity is a stronger determinant of different MIME patterns than impaired glucose metabolism. The large inter-individual variability in the metabolic effects of dietary inulin was explained by differences in baseline glycemic status and MIME signatures. These could be further validated to personalize nutritional interventions in patients with newly diagnosed diabetes.

Accelerated atherosclerosis, hyperlipoproteinemia and insulin resistance in long-term survivors of Hodgkin lymphoma during childhood and adolescence.

Long-term survivors of Hodgkin lymphoma during childhood or adolescence (HL survivors) are at high risk of developing treatment-related late cardiovascular sequelae. In our study we evaluated the presence of modifiable cardiovascular risk factors (hypertension, hyperlipoproteinemia, hyperinsulinemia, obesity), endothelial and inflammatory markers (E-selectin, PAI-1, hs-CRP) and atherosclerotic changes in the common carotid arteries. Assessment was performed in 80 young adult Hodgkin lymphoma long-term survivors at more than 10 years after the potentially cardiovascular toxic anticancer treatment (median age at evaluation 34.7 years; range 24.1-40.9 years). The HL survivors were compared with 83 age- and gender-matched healthy volunteers. The HL survivors showed unfavorable lipid profiles compared to those of healthy controls: triglycerides (p=0.01), total cholesterol (p=0.0004), low density lipoprotein cholesterol (p=0.005). In HL survivors, we found a higher prevalence of hypertension (p=0.004) and insulin resistance - HOMA-IR (p=0.0002). Ultrasonographic examination of both common carotid arteries revealed a higher prevalence of atherosclerotic plaques (p=0.0009) and higher carotid intima-media thickness (p<0.0001) in HL survivors. Markers of oxidative stress (advanced oxidation protein products, oxidized low-density lipoprotein), inflammation (hs-CRP) and endothelial dysfunction (E-selectin, PAI-1) were also higher in HL survivors (p<0.0001, p=0.0002, p=0.0031, p=0.0087, p=0.004, respectively). Adult survivors of Hodgkin lymphoma during childhood and adolescence need closer follow-up with screening of metabolic syndrome components, unfavorable lifestyle factors and early management of these risk factors.

The assessment of the serum C-peptide and plasma glucose levels by orally administered whey proteins in type 2 diabetes mellitus.

A personalized antidiabetic therapy is not yet part of the official guidelines of professional societies for clinical practice. The aim of this study was to evaluate the serum C-peptide and plasma glucose levels in patients with type 2 diabetes mellitus (T2DM) after oral administration of whey proteins. Sixteen overweight T2DM Caucasians with good glycemic control and with preserved fasting serum C-peptide levels (>200 nmol/l) were enrolled in this study. Two oral stimulation tests - one with 75 g of glucose (OGTT) and the other with 75 g of whey proteins (OWIST) - were administered for assessing serum C-peptide and plasma glucose levels in each participant. Both oral tests induced similar pattern of C-peptide secretion, with a peak at 90 min. The serum C-peptide peak concentration was 2.91+/-0.27 nmol/l in OWIST, which was 22 % lower than in OGTT. Similarly, the C-peptide iAUC(0-180) were 32 % lower in the OWIST than in the OGTT (p<0.01). Contrary to OGTT the OWIST did not cause a significant increase of glycemia (p<0.01). Our study showed that the OWIST represents a useful tool in estimation of stimulated serum C-peptide levels in patients with T2DM.

Chronic dietary exposure to branched chain amino acids impairs glucose disposal in vegans but not in omnivores.

BACKGROUND/OBJECTIVES: Branched chain amino acids (BCAA) are among nutrients strongly linked with insulin sensitivity (IS) measures. We investigated the effects of a chronic increase of BCAA intake on IS in two groups of healthy subjects differing in their basal consumption of BCAA, that is, vegans and omnivores. SUBJECTS/METHODS: Eight vegans and eight matched omnivores (five men and three women in each group) received 15 g (women) or 20 g (men) of BCAA daily for 3 months. Anthropometry, blood analyses, glucose clamp, arginine test, subcutaneous abdominal adipose tissue (AT) and skeletal muscle (SM) biopsies (mRNA levels of selected metabolic markers, respiratory chain (RC) activity) were performed at baseline, after the intervention and after a 6 month wash-out period. RESULTS: Compared with omnivores, vegans had higher IS at baseline (GIR, glucose infusion rate: 9.6±2.4 vs 7.1±2.4 mg/kg/min, 95% CI for difference: 0.55 to 5.82) that declined after the intervention and returned to baseline values after the wash-out period (changes in GIR with 95% CI, 3-0 months: -1.64 [-2.5; -0.75] and 9-3 months: 1.65 [0.75; 2.54] mg/kg/min). No such change was observed in omnivores. In omnivores the intervention led to an increased expression of lipogenic genes (DGAT2, FASN, PPARγ, SCD1) in AT. SM RC activity increased in both groups. CONCLUSIONS: Negative impact of increased BCAA intake on IS was only detected in vegans, that is, subjects with low basal amino acids/BCAA intake, which appear to be unable to induce sufficient compensatory changes within AT and SM on a BCAA challenge.

The labile iron pool in monocytes reflects the activity of the atherosclerotic process in men with chronic cardiovascular disease.

The study investigates the relationship between the labile iron pool (LIP) in circulating monocytes and markers of iron metabolism, inflammation, oxidative stress, endothelial dysfunction and arterial elasticity in patients with chronic cardiovascular disease and in healthy volunteers. The patients with a history of CVEs had significantly higher LIP values than did the control group (1.94+/-0.46 microM vs. 1.62+/-0.49 microM, p=0.02). Except for the leukocyte number (WBCs), the groups did not differ in other inflammatory markers (CRPus, CD 163, MPO, MMP-1). Similarly, there were no differences in the markers of endothelial dysfunction (ICAM, VCAM, E-selectin, vWF). The CVE group had higher pulse pressures, levels of markers of impaired arterial elasticity (AI, Young´s modulus, pulsatility, stiffness index), IMT values and ABI values. The LIP concentration was significantly correlated with the transferrin receptor/ferritin ratio, hepcidin levels, VFT content and the ABI and ET values. Patients with a history of CVE have significantly higher concentrations of iron in their intracellular LIP in circulating monocytes than do healthy controls. The independent and significant correlation of LIP with markers of the progression of atherosclerosis and arterial stiffness suggests LIP as a possible novel marker of atherosclerotic activity.

Higher insulin sensitivity in vegans is not associated with higher mitochondrial density.

BACKGROUND/OBJECTIVES: Vegans have a lower incidence of insulin resistance (IR)-associated diseases and a higher insulin sensitivity (IS) compared with omnivores. The aim of this study was to examine whether the higher IS in vegans relates to markers of mitochondrial biogenesis and to intramyocellular lipid (IMCL) content. SUBJECTS/METHODS: Eleven vegans and 10 matched (race, age, sex, body mass index, physical activity and energy intake) omnivorous controls were enrolled in a case-control study. Anthropometry, bioimpedance (BIA), ultrasound measurement of visceral and subcutaneous fat layer, parameters of glucose and lipid homeostasis, hyperinsulinemic euglycemic clamp and muscle biopsies were performed. Citrate synthase (CS) activity, mitochondrial DNA (mtDNA) and IMCL content were assessed in skeletal muscle samples. RESULTS: Both groups were comparable in anthropometric and BIA parameters, physical activity and protein-energy intake. Vegans had significantly higher glucose disposal (M-value, vegans 8.11±1.51 vs controls 6.31±1.57 mg/kg/min, 95% confidence interval: 0.402 to 3.212, P=0.014), slightly lower IMCL content (vegans 13.91 (7.8 to 44.0) vs controls 17.36 (12.4 to 78.5) mg/g of muscle, 95% confidence interval: -7.594 to 24.550, P=0.193) and slightly higher relative muscle mtDNA amount (vegans 1.36±0.31 vs controls 1.13±0.36, 95% confidence interval:-0.078 to 0.537, P=0.135). No significant differences were found in CS activity (vegans 18.43±5.05 vs controls 18.16±5.41 µmol/g/min, 95% confidence interval: -4.503 to 5.050, P=0.906). CONCLUSIONS: Vegans have a higher IS, but comparable mitochondrial density and IMCL content with omnivores. This suggests that a decrease in whole-body glucose disposal may precede muscle lipid accumulation and mitochondrial dysfunction in IR development.

Orally administered whey proteins have comparable effect on C-peptide secretion in healthy subjects as standard C-peptide stimulation tests.

Our study compared total C-peptide secretion after administration of whey proteins and whey proteins in combination with glucose with results of classical tests assessing beta cell function in the pancreas of healthy individuals. Eight young, healthy (7 males, 1 female; aged 20-26 years), non-obese (BMI: 17-25.9 kg/m²) participants with normal glucose tolerance underwent six C-peptide secretion tests. Three secretion tests measured C-peptide response to orally administered substances: whey proteins only (OWT), whey proteins with glucose (OWGT) and glucose only (OGTT); while three secretion tests measured C-peptide response to intravenously administered substances: arginine (AST), glucagon (GST) and glucose (IVGTT). OWT stimulated a greater (93 %, p<0.05) C-peptide response than AST and a 64 % smaller response (p<0.05) than OGTT. OWT also showed lower variability (p<0.05) in C-peptide responses compared to OWGT and OGTT. The greatest total C-peptide response was induced by OWGT (36 % higher than glucose). OWT consistently increased C-peptide concentrations with lower individual variability, while insignificantly increasing glucose levels. Results of this study suggest that both dietology and beta-cells capacity testing could take advantage of the unique property of whey proteins to induce C-peptide secretion.

Short-term dietary intake of C18:1 trans fatty acids decreases the function of cellular immunity in healthy young men.

AIM: In this study, we tested the impact of short-term intake of increased amounts of C18:1 trans fatty acids (TFAs) on parameters of cellular and humoral immunity in healthy young men. METHODS: Twenty-seven healthy young men were subsequently exposed to a standard diet for 7 days and an experimental TFA-enriched diet for 4 days. The mean energy content of these diets was 2,453 and 2,455 kcal/day, with 10, 35 and 55% of energy from proteins, fats and carbohydrates, respectively. Standard diet contained about 0.8 g and experimental diet 10.4 g TFAs. Plasma levels of C18:1 TFAs and immunological parameters were measured. RESULTS: The 4-day increased consumption of C18:1 TFAs led to a significant decrease in mitogen-induced CD69 expression on CD8+ T cells as well as decreased phagocytic activity on neutrophils. After returning to the participants' habitual diet (1 week after the end of the experimental diet), we observed a significant decrease in the mean level of circulating immune complexes. Concentrations of plasma immunoglobulins remained unchanged throughout the study. CONCLUSIONS: Acute impact of higher dietary C18:1 TFA intake on phagocytosis and cell-mediated immunity seems to be suppressive. This finding differs from results describing proinflammatory effects associated with long-term exposure to TFAs.

Markers of Chlamydia pneumoniae and human cytomegalovirus infection in patients with chronic peripheral vascular disease and their relation to inflammation, endothelial dysfunction and changes in lipid metabolism.

Our aim was to detect markers of Chlamydia pneumoniae (CPN) and human cytomegalovirus (HCMV) infection in patients with peripheral vascular occlusive disease and to follow markers of inflammation, endothelial dysfunction and lipid metabolism alteration in patients with active infection. CPN genome was detected in 9 (47.4 %) patients by at least one PCR method. Serological markers of acute CPN infection were found in 5 (26.3 %) subjects; each of them showed also positivity in at least one of the PCR methods. HCMV DNA were detected in 2 (10.5 %) patients; HCMV-specific antibodies were detected in 14 (73.7 %) subjects, however only in IgG subclass. Subjects with HCMV PCR positivity thus showed no serological markers of active HCMV infection. Laboratory findings of acute CPN infection were associated with increased plasma levels of Lp(a), triacylglycerols, atherogenic index of plasma and E-selectin (p < 0.05). No significant differences were found in the other markers, including plasma levels of total cholesterol, ferritin, homocysteine, oxidized LDL, IL-6, IL-8, IL-18, TNF-alpha, soluble forms of VCAM-1 and ICAM-1, von Willebrand factor, C-reactive protein, and plasma nitrites & nitrates. Frequent presence of chlamydial DNA in atheromatous plaques from patients with peripheral vascular disease was confirmed. HCMV DNA was detected only sporadically and with positivity in anamnestic anti-HCMV antibodies (IgG) only, indicating a rare presence of latent virus rather than active replication. Patients with laboratory markers of acute CPN infection exhibited more pronounced alterations in lipid metabolism and endothelial dysfunction.

A comparison of the influence of a high-fat diet enriched in monounsaturated fatty acids and conventional diet on weight loss and metabolic parameters in obese non-diabetic and Type 2 diabetic patients.

AIMS: The aim of our study was to compare the influence of a hypocaloric, high-fat diet enriched with MUFA (M) and conventional diet (C) on weight loss and metabolic parameters in obese non-diabetic and obese Type 2 diabetic subjects over a 3-month period. It was our hypothesis that the enriched diet would be more effective in decreasing blood glucose and glycated haemoglobin (HbA(1c)) than the control diet. METHODS: Twenty-seven Type 2 diabetic patients (54.5 +/- 3.5 years; DM), treated with diet or oral glucose-lowering agents, and 31 obese non-diabetic subjects (53.6 +/- 3.5 years; OB) were randomized to M or C. Individual calculations of energy requirements were based on the formula: [resting energy expenditure (REE) x 1.5] - 600 kcal. Subjects were assessed by a dietitian every 2 weeks and by a physician every month. Statistical analyses were carried out between the four groups--DM/M, DM/C, OB/M and OB/C--using pair Student's test and anova. RESULTS: After 3 months, body weight, waist-hip ratio, total body fat, levels of C-peptide, triglycerides and homeostasis model assessment (HOMA) decreased in all four groups (P < 0.01). However, fasting blood glucose and HbA(1c) decreased (P < 0.01) and high-density lipoprotein cholesterol increased significantly only in the DM/M group (P < 0.05). In general, M was well tolerated. CONCLUSIONS: Individualized M and C diets were successful in improving metabolic and anthropometric parameters in both the obese non-diabetic and the Type 2 diabetic subjects. Although the superiority of the higher fat diet did not reach statistical significance, the decline in blood glucose and HbA(1c) in the Type 2 diabetic group on M was encouraging.

Hyperlipoproteinemia impairs endothelium-dependent vasodilation.

Atherogenic lipoproteins can cause endothelial dysfunction in the initial stage of atherogenesis. In our study we examined 134 patients with defined hyperlipoproteinemia (non-HDL cholesterol>4.1 mmol/l or triglycerides>2.5 mmol/l or taking any of lipid lowering drugs)--94 men and 40 women. The subgroup of controls of comparable age contained 54 normolipidemic individuals--30 men and 24 women. Patients with hyperlipoproteinemia revealed significantly lower ability of endothelium-dependent flow-mediated vasodilation (EDV) measured on brachial artery (4.13+/-3.07 vs. 5.41+/-3.82 %; p=0.032) and higher carotid intima media thickness than normolipidemic controls (0.68+/-0.22 vs. 0.58+/-0.15 mm; p=0.005). In regression analysis, EDV correlated significantly with plasma concentrations of oxLDL (p<0.05) HDL-cholesterol (p<0.05), Apo A1 (p<0.05), ATI (p<0.01) and non-HDL cholesterol (p<0.05). Patients with hyperlipoproteinemia showed higher plasma levels of oxLDL (65.77+/-9.54 vs. 56.49+/-7.80 U/l; p=0.015), malondialdehyde (0.89+/-0.09 vs. 0.73+/-0.08 micromol/l; p=0.010) and nitrites/nitrates (20.42+/-4.88 vs. 16.37+/-4.44 micromol/l; p=0.018) indicating possible higher long-term oxidative stress in these patients.

[Diabetic diet and reduction diet are worthy of a basic discussion of their paradigms]. / Diabetická i redukcní dieta zasluhují základní diskusi o svých paradigmatech.

Present knowledge of etiopathogenesis of various types of diabetes postulate substantial differences between type I and type II diabetes. Whereas type I diabetes results from autoimmune destruction of pancreatic B-cells and subsequent absolute lack of insulin, type II diabetes is connected with insulin resistance and frequently with rather relative lack of sometimes absolutely elevated plasmatic insulin. From the viewpoint of the diet therapy an access to both types of diabetes fairly differs. Whilst in type I diabetes it is necessary to find out relationship among preprandial insulin dose, received carbohydrates, and expected physical activity soon after meal, treatment of type II diabetes is based in an effort to influence insulin resistance and the whole metabolic syndrome. Therefore, on one side carbohydrates with low glycemic index and plenty of fibers are administered in a diet and on the other side monoenic and polyenic fatty acids are preferred to saturated fatty acids and trans fatty acids are continuously reduced in a diet. Of course, diets for patients with overweight and for obese patients are low energy. From the viewpoint of the current structure of the diabetic diets it is suitable to differentiate diets for patients with type I and type II diabetes. Instead of the use of a fix proportion of nutrients we have to discuss diets with regard to a qualitative composition of fatty acids in fats, glycemic index of saccharides, and an amount of fibers in the diet.

[Ferritin, oxidative stress and coronary atherosclerosis]. / Feritin, oxidacní stres a koronární ateroskleróza.

BACKGROUND AND AIM: In the recent years several studies showed the association between body iron stores, represented by serum ferritin, and atherosclerosis. It was proposed that iron bound to ferritin catalyzes the formation of highly reactive forms of oxygen free radicals which subsequently cause the oxidative modification of atherogenic lipoproteins. Aim of our study was to compare serum ferritin concentrations and certain markers of oxidative stress in patients with and without coronarographically assessed coronary vascular disease. METHODS AND RESULTS: Measurements were performed in 216 subjects at the age of 35-60 years. The patient group included 76 patients with coronarographically assessed coronary vascular disease (CVD) (mean age 51.16 +/- 5.713 years) and 140 healthy controls (mean age 50.21 +/- 5.331 years). The plasma concentration of ferritin was higher in patients (169.04 +/- 63.899 micrograms/l) than controls (87.70 +/- 41.394 micrograms/l), p < 0.001. The group of patients revealed significantly lower plasma concentrations of anti-oxLDL antibodies, nitrites/nitrates, tocopherol and high density lipoprotein cholesterol (HDL-cholesterol) than controls; on the contrary patients had significantly higher concentrations of hemoglobin, thrombocytes and triacylglycerols. In the whole cohort of investigated subjects, ferritin correlated positively with retinol, body mass index (BMI), total-cholesterol, triacylglycerols, low density lipoprotein cholesterol (LDL-cholesterol), blood glucose, creatinine, uric acid, alaninaminotransferase (ALT), aspartateaminotransferase (AST), hematocrite, erythrocytes, with occurrence of CVD and with sex. Inverse correlation was observed between ferritin and HDL-cholesterol. CONCLUSIONS: Our observations are consistent with the hypothesis that high stored iron levels, measured by serum ferritin concentrations, may contribute to the oxidative stress and thus elevate the risk for development of CVD.

[Sonographic measurement of intimal thickness of the common carotid artery in diabetics]. / Sonografické merení sírky intimy spolecné karotické tepny u diabetiku.

Incidence of atherosclerotic cardiovascular diseases in diabetics is known to be 2-4 times higher than in nondiabetic subjects. Intima-media-thickness of common carotid artery (IMT ACC) measured by B-mode sonography positively correlates with the severity of atherosclerotic changes in coronary arteries. This study compares sonographically assessed IMT ACC in patients with type 2 diabetes mellitus (27 patients, mean age 66.57 +/- 6.06 years) vs. 66 nondiabetic subjects (mean age 63.58 +/- 9.09 years). Intima-media thickness in diabetics was significantly higher when compared with the control group (0.826 +/- 0.29 mm vs. 0.647 +/- 0.26 mm). In the whole cohort of investigated subjects IMT ACC positively correlates with age. When adjusted for age, the mean IMT ACC level was significantly higher in men than in women.

[Type 1 diabetes mellitus in the aged]. / Diabetes mellitus I. typu ve vyssím veku.

Diabetes mellitus type I was till recently considered a disease affecting children and young adults. Research in the past several years provided evidence that this type of diabetes is found in all age groups and that the majority develops after the age of 35 years. Diagnostic possibilities of type I diabetes were markedly extended due to the introduction of radioimmunoassay of antibodies against glutamate decarboxylase. This examination has a 82% sensitivity and 100% specificity in diabetes. Diabetes mellitus in advanced age is manifested much less dramatically than in child age. It is found in non-obese subjects and usually its clinical manifestation is gradual. At first the patients are as a rule treated by diet. After several months usually sulphonylurea derivatives are started and only later insulin. If the diagnosis of diabetes mellitus type I is beyond doubt due to autoimmune disease, assessed preferably by antiGAD antibodies, immediate substitution therúpy with insulin is fully indicated. The latter can protect the residual function of B cells of the islets of Langerhans of the pancreas and contribute thus to the prevention of microvascular complications of diabetes mellitus.

Fasting plasma insulin levels in an unselected Prague suburban population.

OBJECTIVE: The aim of the study was to determine the levels of fasting plasma insulin in an unselected population of a Prague suburban community and correlate the levels of insulin with other metabolic and anthropometric parameters which could be directly or indirectly associated with insulin levels. RESEARCH DESIGN AND METHODS: A total of 835 adult inhabitants, the Prague suburban community, were examined. Mean age of examined people was 44.9 +/- 16.9 years, the group included 370 men and 465 women, 189 of the latter were in the menopause. The parameters examined included the fasting plasma levels of insulin, glycaemia, total cholesterol, HDL cholesterol and triacylglycerols; LDL cholesterol and, using the basic anthropometric data, the body mass index (BMI) and the waist/hip ratio (WHR) were calculated. RESULTS: The levels of all parameters were divided in ten-year groups of men and women. The average levels of fasting plasma insulin in all ten-year groups of men and women were normal. We found in the men small but constant rise of fasting insulinaemia in the decades. This was not observed in women, where the insulin levels were similar up to the time after menopause, then the level of average plasma insulin rose significantly. We found the positive correlation of plasma insulin levels with triacylglycerol levels (p < or = 0.001), BMI (p < or = 0.001) and WHR (p < or = 0.001) and a negative correlation with plasma HDL cholesterol (p < or = 0.001) in the whole group of probands. No significant correlation was demonstrated between fasting insulinaemia and total or LDL cholesterol. When dividing the group by age and sex, the strongest positive correlations were seen between insulin and triacylglycerols, glycaemia, BMI, and WHR, and negative correlations between insulin and HDL cholesterol. CONCLUSION: Fasting plasma insulin levels in an unselected population were within the normal range, but follow a continuous and steady upward course in men while did not change until after the menopause when they bounce in women; compared to insulin levels in younger women, insulinaemia does not increase up to 55 years of age. The strongest positive correlations were demonstrated between plasma insulin and triacylglycerols, and between insulin and BMI and WHR in men and postmenopausal but not premenopausal women whereas a negative correlation was observed between fasting plasma insulin and HDL cholesterol.

"Healthy Dubec" -design of a joint Czech-American community project for the reduction of cardiovascular and cerebrovascular disease (adapted from American experience).

The project is a combination of individual and community-based intervention which adapted and modified methods and techniques originally used in The Three-City Community Study and The Stanford Five-City Project in a small community outside Prague. The goal is to reduce cardiovascular and cerebrovascular risk factors by primary and secondary prevention, using a community-based approach. 61.5% of examined population with the low risk score during the baseline survey was exposed to intervention by community-based methods. 38.5% of adult population was included in intervention activities within the framework of secondary prevention in high risk groups. There are described: the method of community oriented intervention and the intervention oriented on high risk groups - nutrition intervention, quit smoking activities, stress control, physical activity promotion.
