AbstractSalusins have emerged as a new biomarker that reflects an increased inflammatory state, which is associated with cardiovascular risk. We investigated the predictive value and usefulness of salusins as an inflammatory biomarker in obese children. This prospective cohort study included 75 obese children and 101 healthy children (as a control group). Salusin-α, Salusin-β, and various cardiovascular parameters were assessed in both groups. Correlation analyses of Salusin-α and Salusin-β with body mass index standard deviation scores and inflammatory and cardiovascular markers were performed. The mean patient age was 11.9±2.4 years for the obese group and 12.5±2.1 years for the control group. The obese children had a significantly higher heart rate, systolic blood pressure, diastolic blood pressure, epicardial adipose tissue thickness, and left ventricular mass than did the children in the control group. There was no significant correlation between Salusin-α and Salusin-β and body mass index; however, there was a negative correlation between Salusin- α and diastolic blood pressure (r = 0.277, p = 0.004). Overall, there was no significant difference in the Salusin-α and Salusin-β levels between obese and healthy children. However, a negative correlation was found between Salusin-α and diastolic blood pressure. Although this result suggests that Salusin-α might be an early marker of cardiovascular involvement in obese children, further studies are needed to demonstrate the predictive value of salusins.

Objective – to analyze the association of risk factors with the 1666 A>C polymorphism of the AGTR1 gene in patients with essential hypertension.Material and methods. 100 patients were screened, 72 of whom were genotyped. The control group consisted of 48 healthy individuals who did not differ in gender and age, and with the group of patients.Results. The obtained data confirmed that the level of blood pressure elevation is associated, to some extent, with modified (diabetes mellitus 2, smoking, body mass index) and unmodified factors (family history, gender) the risk of essential hypertension. The results of the analysis of blood pressure levels considering the A1166C polymorphism of the AGTR1 gene showed that the values of systolic and diastolic blood pressure in the group of patients with C-allele carriers were higher than in carriers of AA genotype: SBP – by 5.38% (p<0.05), DBP – by 5.15% (p<0.05). Conclusions. The level of blood pressure in patients with essential hypertension depends on body mass index and smoking. In carriers of the C-allele of the AGTR1 gene (A1166C), the level of systolic and diastolic blood pressure exceeds the ones of the carriers of the AA genotype. The presence of the C-allele of the AGTR1 gene (A1166C) almost doubles the risk of severe essential hypertension [OR = 2.75; p = 0.037].

Obesity in childhood, which is associated with cardiovascular risk factors such as hypertension, is on the increase. Countermeasures are necessary. In this paper, we present the baseline and final data from the StEP TWO programme, a prospective study to prevent overweight and obesity in primary schools. Methods: We recorded and calculated, from 1689 children, anthropometric data, including analyses of bioelectric impedance, waist and hip circumferences, body mass index and its standard deviation, and the ratio of waist to hip. Blood pressure was measured after 5 minutes at rest. From the three schools involved in a programme of intervention, 121 children were invited to take part, and 40 (33.1 per cent) completed the programme. The effect was compared with 155 overweight and obese children identified at the 4 control schools. Results: 830 (49.5 per cent) boys and 848 girls (50.5 per cent) took part. Their mean age was 8.2 plus or minus 1.3 years, their height was 1.31 plus or minus 0.09 metres, they weighed 30.0 plus or minus 8.2 kilograms, and their mean index of body mass was 17.1 plus or minus 2.9 kilograms per metre squared. Of the children, 7.3 per cent were obese, 10.4 per cent were overweight, 75.7 per cent had normal weights, and 6.6 per cent were underweight. Resting hypertension was observed in 2.3 per cent of the children. Increased blood pressure was associated with a higher body weight, body mass index, standard deviation score for body mass index, and waist and hip circumferences (each p < 0.001), but not with the ratio of waist to hip. Hypertension at rest was also found in 11.0 per cent of obese children, 4.4 per cent of those who were overweight, 1.2 per cent of those with normal weight, and 1.0 per cent of underweight children (p < 0.001). After the intervention, the increase of the body mass index tended to be lower in those in whom we had intervened (p = 0.069), and in these the decrease of the standard deviation score for body mass index was significantly higher (p = 0.028). Systolic blood pressure was reduced by about 10 millimetres of mercury in those in whom we had intervened (p = 0.002), while there were no changes in the control group. Diastolic blood pressure was lowered by 3 millimetres of mercury, but this was not significant. Conclusion: Obese children had the highest values for systolic and diastolic blood pressure. Increased levels of blood pressure are associated with other parameters of obesity, such as the circumference of the waist and hip. Early preventive measurements in childhood are necessary, and appropriate intervention appears to be effective.

Ventricular Repolarisation

Abstract Objective: Ventricular repolarisation changes may lead to sudden cardiac death in obese individuals. We aimed to investigate the relationship between ventricular repolarisation changes, echocardiographic parameters, anthropometric measures, and metabolic syndrome laboratory parameters in obese children. Methods: The study involved 81 obese and 82 normal-weight healthy children with a mean age of 12.3 ± 2.7 years. Anthropometric measurements of participants were evaluated according to nomograms. Obese patients were subdivided into two groups; metabolic syndrome and non-metabolic syndrome obese. Fasting plasma glucose, fasting insulin, and lipid profile were measured. QT/QTc interval, QT/QTc dispersions were measured, and left ventricular systolic and diastolic measurements were performed. Results: Body weight, body mass index, relative body mass index, waist/hip circumference ratio, and systolic and diastolic blood pressures were significantly higher in obese children. QT and QTc dispersions were significantly higher in obese children and also obese children with metabolic syndrome had significantly higher QT and QTc dispersions compared to non-metabolic syndrome obese children (p < 0.001) and normal-weight healthy children (p < 0.001). Waist/hip circumference ratio, body mass index, and relative body mass index were the most important determinant of QT and QTc dispersions. Left ventricular wall thickness (left ventricular posterior wall thickness at end-diastole, left ventricular posterior wall thickness at end-systole, interventricular septal thickness at end-diastole) and left ventricular mass index were significantly higher and ejection fraction was lower in obese children. Left ventricular mass index and interventricular septal thickness at end-diastole were positively correlated with QT and QTc dispersions. Conclusions: Our study demonstrated that QT/ QTc interval prolongation and increase in QT and QTc dispersion on electrocardiogram may be found at an early age in obese children.

Background Definition of childhood overweight/obesity should aim to identify children with excess body fat in order to treat the associated adverse health outcomes. Objective To investigate relationship between Body Mass Index (BMI) and systolic blood pressure (SBP) and diastolic blood pressure (DBP) values in children between the ages of 6 and 14 year old. Materials and Methods Secondary data gathered from public health screening days at Child Health and Diseases Polyclinic of Kocaeli Metropolitan Municipality Maternity and Children Hospital on 1899 children. Each child was classified on the basis of age- and sex-specific Body Mass Index percentile (BMI%) as normal weight (BMI% < 85th), overweight (BMI% ≥ 85th and < 95th), or obese (BMI% ≥ 95th). Systolic and diastolic blood pressures were compared among age-sex-BMI percentile groups. Results SBP and DBP values are higher in obese and overweight children compared to normal children. Among all children in this study, being overweight and obese increased the likelihood of elevated SBP and DBP values after adjusting for age.  Blood pressure (BP) is increasing with increasing BMI in all age groups (6 to 14 year old) and this is also found at a young age. The same trend is also present within the normal BMI% group. Conclusions Our results show that BMI is associated with elevated systolic and diastolic blood pressure in overweight and obese children as well as children in normal BMI% group. BP is increasing with increasing BMI values even in normal group but the increase is more in obese children. Hence, maintaining age related normal growth increase in the BMI in childhood is important in preventing higher BP values later in life.Keywords: Body Mass Index; BMI; Blood pressure; Children DOI: http://dx.doi.org/10.3126/nje.v1i3.5574 Nepal Journal of Epidemiology 2011;1(3) 101-105

Atrial Electromechanical Delay

Background and Objective: Childhood obesity is one of the worldwide health problems with an increasing prevalence and accompanied by severe morbidity and mortality. It is a serious predisposing risk factor especially for the development of cardiovascular diseases and arrhythmias. Electromechanical delay (EMD) is known to be a predictor for the development of atrial fibrillation (AF). Our study aims to investigate whether EMD, which is a predictor of AF, prolongs in obese children or not. Material and Methods: The study included 59 obese patients aged between 8–18 years and 38 healthy patients as the control group with a similar age and gender. All the individuals underwent transthoracic echo and tissue Doppler echocardiography. Systolic and diastolic left ventricular (LV) functions, inter- and intra-atrial electromechanical delay were measured by tissue Doppler imaging (TDI) and conventional echocardiography. Results: Obese patients had significantly lengthened P-wave on surface ECG to the beginning of the late diastolic wave (PA) lateral, PA septum, intra- and inter-atrial electromechanical delays when compared with the control group (p < 0.001, p = 0.001, p < 0.001 and p < 0.001, respectively) Inter-atrial EMD and intra-atrial EMD correlated positively with body mass index (BMI) values (r = 0.484, p < 0.001 and r = 0.376, p = 0.001; respectively) BMI was significantly related with inter-atrial EMD (β = 0.473, p < 0.001) However, there was no relationship between inter-atrial EMD and serum glucose and platelet count. Conclusion: In our study, we declared that electromechanical delay was increased in obese children when compared to the control group and intra- and inter-atrial electromechanical delay was in correlation with body mass index. Furthermore, we discovered that BMI is an independent predictor of the inter-atrial EMD in obese children.

Aims: StEP TWO is a school- and family-based intervention consisting of extra lessons, healthy nutrition and physical education for overweight and obese children in primary schools, aimed at reducing body mass index by maintenance or reduction of weight, and improving motor abilities. We analysed differences in changes in anthropometric, cardiovascular and obesity parameters between children who underwent intervention, non-participants in intervention, and controls. Methods: Anthropometric data and waist circumference were recorded for 1678 children; body mass index and body mass index–standard deviation score were calculated. Blood pressure was measured after 5 minutes at rest. 121 overweight and obese children enrolled at 3 schools involved in programmes of intervention were invited to take part; 40 of them completed the programme from November 2003 to July 2004. Of these overweight children, 74 were invited, but did not take part. As controls, we enrolled 155 overweight and obese children from 4 other schools. Results: After the programme, the children involved in intervention showed a lower increase in the body mass index (0.3 plus or minus 1.3 versus 0.7 plus or minus 1.2 kilograms per metre squared) and an approximately three times higher diminution of the body mass index–standard deviation score in comparison with their controls (−0.15 plus or minus 0.26 versus 0.05 plus or minus 0.27). Systolic blood pressure was significantly lowered by 9.5 plus or minus 19.6 millimetres of mercury in those involved in intervention, but increased in the control group by 0.5 plus or minus 16.5 millimetres of mercury. Among those invited but not participating, the increase of the body mass index (0.5 plus or minus 1.3 kilograms per metre squared) was less, and the reduction of the body mass index-standard deviation score (−0.09 plus or minus 0.31) and systolic blood pressure (−5.3 plus or minus 15.6 millimetres of mercury) was higher than in the control group. Overweight but not obese children seem to benefit from a screening examination alone. Conclusions: Early preventive measures in schools are necessary and effective for overweight and obese primary school children. The screening itself seems also to have a minor positive effect, especially for overweight children. Sustainability of the observed improvements over a longer period remains to be confirmed.

Background: The purpose of this study was to investigate the effects of Nordic Walking compared to conventional walking on aerobic capacity, the lipid profile, left ventricular ejection fraction, body mass, and body mass index in women over 55 years old. Methods: The study was comprised of 74 women over 55 years of age. Participants were randomized to the Nordic Walking (n = 38) or conventional walking (n = 36) training groups. The echocardiogram, treadmill exercise stress test, lipid profile, and body mass were assessed at baseline (pretest) and after 12 weeks (posttest). Results: The authors found a significant main effect over time in duration (effect size [ES] = 0.59, P < .0001), distance covered (ES = 0.56, P < .0001), peak oxygen consumption (ES = 0.43, P < .0001), metabolic equivalent (ES = 0.29, P < .0001), peak heart rate (ES = 0.2, P < .0001), peak diastolic blood pressure (ES = 0.11, P = .0045), total cholesterol (ES = 0.26, P < .0001), and low-density lipoprotein cholesterol (ES = 0.16, P = .0005). The authors did not observe a time versus group interaction or the effect between groups. Post hoc tests revealed significant pretraining to posttraining differences in low-density lipoprotein cholesterol after the Nordic Walking training program and in peak diastolic blood pressure after the conventional walking training program. The heart rate, systolic blood pressure, and diastolic blood pressure at rest, peak diastolic blood pressure, somatic parameters (body mass and body mass index), and left ventricular ejection fraction did not change in either group. Conclusions: Both training programs resulted in increases in aerobic capacity and decreases in total cholesterol.

The aim – to study the features of structural and functional remodeling of the left ventricle in patients suffering from arterial hypertension with concomitant hypothyroidism and to determine clinical and past medical history and laboratory factors associated with their development. Materials and methods. 50 patients suffering from hypertension with concomitant hypothyroidism were enrolled into the study. Depending on the level of thyroid stimulating hormone in the serum the examined patients were distributed into two groups of 25 patients with the compensated and 25 with decompensated course of hypothyroidism. The control group consisted of 30 patients with hypertension in which the pathology of the thyroid gland was excluded. The comparison of the main parameters of the echocardiography study of the myocardium has been performed depending on hypothyroidism compensation. Assessment of parameters of transmitral diastolic blood flow has been performed. A regression analysis has been conducted to detect the relation of clinical and past medical history factors and echocardiographic parameters with the development of diastolic dysfunction by E/A ratio. The values of central hemodynamics have been studied for evaluation of the contractile function of the myocardium. Results and discussion. According to the results of the echocardiography of both examined groups it has been found that the final systolic and stroke volume exceeded the parameters of the control group. The mean value of the left ventricle ejection fraction was statistically significantly lower than in the control group (p=0.004). The left ventricle myocardial mass in patients with hypothyroidism was statistically significantly greater than in the control group. It was proved that in patients, who were diagnosed with decompensated hypothyroidism, the mean value of the left atrium size to growth by the degree of 2.7 was statistically significantly higher than in the control group (p=0.01), whereas the average value of the ratio of the size of the left atrium to the surface area of the body had no statistically significant differences between the groups. It has been found that in both groups the proportion of patients with diastolic dysfunction in which the E/A ratio was less than 1.0 was higher than in the control group (р=0.01 and p=0.03, respectively). The independent factors of diastolic dysfunction of the left ventricle in patients with hypertension in the presence of hypothyroidism have been found. Conclusions. In the presence of decompensated hypothyroidism in patients with arterial hypertension, both with obesity and with normal body mass index, left ventricular mass indexes were significantly higher in comparison with a control group. Regardless of the compensation of the thyroid state in patients with arterial hypertension, the ejection fraction was significantly lower. According to regression analysis, independent factors for the development of diastolic dysfunction in patients with arterial hypertension and hypothyroidism with a body mass index ≥ 30 kg/m2 is the index of mass of the left ventricular myocardium, determined by the degree of 2.7, the level of total cholesterol to statistical significance – the level of office systolic blood pressure and the duration of hormone replacement therapy for hypothyroidism; with body mass index < 30 kg/m2 – age and left atrial index, determined by body surface area. For patients with arterial hypertension and reduced thyroid gland function, violation of the left ventricular myocardial relaxation is typical as evidenced by a higher proportion of patients with a decrease in E/A to less than 0.8 in these patients.

ABSTRACTAimLongitudinal global strain (LGS) is reduced in obese patients with normal ejection fraction of the left ventricle. TAPSE/PAPS ratio, recently described, may be a step forward a more efficient RV function evaluation.There are still few publications in the application of these methods in pediatric patients.MethodsThis case-control study compared 104 children aged 5-18 years between October 2017 and February 2019, 52 obese children with body mass index (BMI) > +2 SD, and 52 matched controls.They were screened for other cardiovascular risk factors like insulin resistance or hypercholesterolemia. A complete echocardiography including standard and functional parameters was performed.ResultsWe found that obese children presented poor systolic function (LGS −15,90 ± 3,84 %) in comparison with non-obese children (−19,44 ± 5,75 %, p=0,001). LGS correlated positively with body mass index (BMI).Standard echocardiography also revealed cardiomegaly and hypertrophy.TAPSE/PASP ratio correlated negatively with triglycerides levels (β −0,402, p=0,014). Diastolic function was poor in those with HOMA-IR (β −0,375, p=0,016) and hypertriglyceridemia (β −0,375 p=0,024).ConclusionWe think that is necessary to perform a standarised cardiovascular evaluation in obese children for early identification of subclinical dysfunction especially in those with insulin resistance and dyslipidemia
