Leptin and cardiometabolic risk factors in overweight persons in young age

Aim of the study was to investigate the associations of leptin levels with cardiometabolic risk factors in overweight young people. Material and methods. From a representative sample of the young population of the Oktyabrsky district of Novosibirsk at the age of 25–35 years (636 people), all overweight people (196 persons) and people with normal body weight (control group 197 persons) were chosen for determination of serum leptin (393 people). Study design – case-control. Overweight was determined according to body mass index (BMI) ≥ 25 kg/m 2 . Leptin levels were determined by immunofluorescence analysis (IFA) using Elisa test systems (Diagnostics Biochem Canada Inc., Canada) on an IFA analyzer Multiscan EX (Finland). For calculations, the median and interquartile range were used (Me [25; 75]). Results . Leptin level in the study group with BMI ≥ 25 kg/m 2 was 4 times higher than in the control group (17.0 [8.6; 36.9] and 4.4 [1.5; 13,1] ng/ml, respectively). The indicators of risk factors in leptin content quartiles were analyzed: it was found that in men and women included in leptin Q4the waist circumference, hip circumference, BMI, blood pressure, triglyceride content were more than in Q1; they also showed an increase in the frequency of metabolic syndrome and a decrease in the level of high-density cholesterol. In addition, in men, in contrast to women, leptin Q4 showed an increase in total cholesterol and low-density cholesterol level. According to the ROC analysis, all studied anthropometric parameters reflecting overweight were associated with a high level of blood leptin, and the maximum associations were found between obesity grade II (BMI more than 35 kg/m 2 ) and normal body weight – area under ROC curve 0.91, p < 0.001. The threshold value of the leptin level for detecting MS in men is 6.5 ng/ml, in women 25.8 ng/ml. Conclusions . Serum leptin levels are associated with cardiometabolic risk factors and metabolic syndrome in young population, and leptin levels above 6.5 ng/ml in men and 25.8 ng/ml in women are characteristic of individuals with metabolic syndrome.

Circulating levels of MCP-1, VEGF-A, sICAM-1, sVCAM-1, sE-selectin and sVE-cadherin: Relationship with components of metabolic syndrome in young population

IntroductionInflammation and endothelial dysfunction are considered the primary manifestations of the cardiovascular disease. Studies have established a relationship among components of metabolic syndrome (MetS) with inflammatory markers and the loss of permeability, vasoconstriction and vasodilatation endothelial. ObjectiveTo determine the relationship among the concentrations of soluble endothelial dysfunction molecules and inflammation cytokines and components of the metabolic syndrome in young population. Material and methodsA study was performed in 240 young adult students ages 18–28 years. To define the presence of clinical and metabolic alterations and MetS the modified ATP-III criteria was considered. In all subjects were determined sociodemographic characteristics, anthropometric measures and the metabolic profile. Circulating levels of MCP-1, VEGF-A, sICAM-1, sVCAM-1, sE-selectin and sVE-cadherin were determined by ELISA immunoassay (Bioscience). Statistical analysis was performed using STATA statistical software v. 9.2. ResultsFrom all the participants, 44.6% had obesity, 59.9% had abdominal obesity, 49.6% low HDL-c and 16.7% high levels triglycerids. The 16.25% of the population showed 3 or more components of the MetS. Elevated MCP-1, sICAM-1 and sE-selectin levels were linked to the presence of obesity. In a model adjusted by age–gender, high soluble levels of MCP-1 and VEGF-A were linked with abdominal obesity (OR=1.83; 1.02–3.28 and OR=2.03; 1.15–3.56, respectively), as well as to the presence of the 2 components of MetS. sVCAM-1 levels were associated with impaired glucose (OR=4.74; 1.32–17.0); sE-selectin with low HDL-c (OR=1.99; 1.05–3.75), although sICAM-1 and sVE-cadherin were associated with impaired systolic blood pressure (OR=4.04; 1.24–13.1 and OR=6.28; 1.90–20.7, respectively). ConclusionLevels of circulating MCP-1 and VEGF-A were associated with adiposity, levels of sVCAM-1 with the presence of impaired glucose, sE-selectin with low HDL-c, while the levels of sICAM-1 and sVE-cadherin were associated with impaired systolic blood pressure in young adults independently of other traditional risk factors.

Prevalence and Correlates of Metabolic Syndrome in Young Population: A Cross Sectional Study

Background: The Metabolic Syndrome (MS) is emerging as one of the major public health problem all over the world including India. It confers increased risk of Cardiovascular Disease (CVD) and Diabetes Mellitus (DM), both of which pose a huge burden over the society and economics. This study was conducted to assess the prevalence and correlates of MS in young population. Settings and design: A cross-sectional study was performed in Department of Medicine of a rural teaching tertiary care hospital in central India. Materials and methods: In all consecutive study subjects, a National Cholesterol Education Programme Adult Treatment Panel (NCEP ATP – III) criteria was applied to assess the magnitude of MS. Statistical analysis: Prevalence of MS was expressed in percentage. For determining the association of risk factors with MS, we used Student’s t-test to test for continuous variables Chi square for categorical variables and Fisher exact test in the case of small cell sizes (expected value<5). Association was considered statistical significant when P value was ≤ 0.05. Results: The magnitude of MS was 11.2%. Conclusion: Metabolic syndrome exists in significant number of young student population. The early identification of MS and associated risk factors can help to prevent or delay MS, diabetes and CVD by modifying their lifestyle.

Management of Metabolic Syndrome in Young Population

Metabolic syndrome is a complex disorder associated with several cardiovascular risk factors resulting in a 2.5-fold increase in cardiovascular mortality in adults. However, over the last 20 years, the same association has been demonstrated in the young population, and it is also related to a parental history of the syndrome. However, the root of the problem could be a high risk factor profile for metabolic syndrome in children and adolescents, as it has been demonstrated over the last 20 years. It has been shown that the association of obesity, alterations of glucose and lipids metabolism, and high blood pressure are responsible for early atherosclerotic lesions at autopsy as observed in young people. The prevalence of several risk factors for cardiovascular diseases has increased in the Brazilian population, as has that of obesity, a cause of great concern because of its importance as one of the metabolic syndrome components. The anthropometric patterns of the Brazilian population have changed over the last 30 years from undernourishment to weight excess, regardless of age, sex, or socioeconomic level. The identification of such individuals, followed by primary preventive measures, changes in lifestyle, and pharmacologic treatment, should be implemented, aiming at reducing the cardiovascular risk in countries undergoing economic transition, such as Brazil. The measures recommended for that age group should focus on changing lifestyle through adoption of healthy habits such as avoiding excessive intake of calories, salt, saturated fat, and cholesterol and engagement in regular physical activity without smoking.
