“…The present study extends the results of our previously published studies (19,20) and is in line with international results demonstrating stabilization of overweight in the same age groups in boys and girls (9,24). Stabilization in BMI was also confirmed in different age categories in school-aged children in the Czech Republic (19,20) as well as internationally in different countries across the globe (25)(26)(27).…”

SUMMARYObjective: Overweight and obesity in adolescents is associated with many health risks and considerable direct and indirect healthcare costs. The purpose of this study is to examine trends in the prevalence of overweight and obesity in 11-, 13-and 15-year-old adolescents in the Czech Republic from 1998 to 2014.Methods: Data from five self-reported survey rounds (1998, 2002, 2006, 2010, and 2014) of the Health Behaviour in School-aged Children Study (HBSC) were used to assess trends in overweight and obesity among Czech adolescents. The total sample consisted of 19,103 adolescents (51.2% girls). A logistic regression analysis was used to assess trends in different age and gender categories.Results: From 1998 to 2014 a significant increase in the prevalence of overweight and obesity was observed among boys in all age categories (11 years old 22.2% 1998 -28.3% 2014 ; 13 years old 17.9% 1998 -26.7% 2014 ; 15 years old 9.8% 1998 -20.8% 2014 ) and among 15-year-old girls (6.0% 1998 -10.9% 2014 ). None of the age and gender categories showed an overall decrease over the 16-year period. In boys, the prevalence of overweight was significantly higher with steeper negative trends compared with girls. However, stabilization in overweight rates was observed between 2010 and 2014 in all age and gender groups.Conclusion: Nationally representative self-reported data show a significant increase in overweight (including obesity) prevalence among children from 1998 to 2014 in the Czech Republic. The results also suggest stabilization in overweight prevalence between 2010 and 2014. Continuing research is needed to determine future trends while interventions aimed at reducing overweight and obesity in children should be implemented on different levels of public policy.

“…9 A recent report shows that although the obesity trends have plateaued in some countries, youth overweight and obesity among 11-to 15-year-olds remains high in Europe and North America. 16 Childhood overweight tracks strongly into adulthood, and thus, also a rise in BP can be expected to continue in the younger-age classes. Despite increasing BMI, overweight, and obesity among Finns, the BP levels of all age groups have decreased remarkably during the last 30 years, albeit they remain still high.…”

Repeated Blood Pressure Measurements in Childhood in Prediction of Hypertension in Adulthood

et al. 2016

Hypertension may be predicted from childhood risk factors. Repeated observations of abnormal blood pressure in childhood may enhance prediction of hypertension and subclinical atherosclerosis in adulthood compared with a single observation. Participants (1927, 54% women) from the Cardiovascular Risk in Young Finns Study had systolic and diastolic blood pressure measurements performed when aged 3 to 24 years. Childhood/youth abnormal blood pressure was defined as above 90th or 95th percentile. After a 21- to 31-year follow-up, at the age of 30 to 45 years, hypertension (>140/90 mm Hg or antihypertensive medication) prevalence was found to be 19%. Carotid intima-media thickness was examined, and high-risk intima-media was defined as intima-media thickness >90th percentile or carotid plaques. Prediction of adulthood hypertension and high-risk intima-media was compared between one observation of abnormal blood pressure in childhood/youth and multiple observations by improved Pearson correlation coefficients and area under the receiver operating curve. When compared with a single measurement, 2 childhood/youth observations improved the correlation for adult systolic (r=0.44 versus 0.35, P <0.001) and diastolic (r=0.35 versus 0.17, P <0.001) blood pressure. In addition, 2 abnormal childhood/youth blood pressure observations increased the prediction of hypertension in adulthood (0.63 for 2 versus 0.60 for 1 observation, P =0.003). When compared with 2 measurements, third observation did not provide any significant improvement for correlation or prediction ( P always >0.05). A higher number of childhood/youth observations of abnormal blood pressure did not enhance prediction of adult high-risk intima-media thickness. Compared with a single measurement, the prediction of adult hypertension was enhanced by 2 observations of abnormal blood pressure in childhood/youth.

“…[1][2][3] Pediatric obesity is often carried into adulthood 4,5 and is associated with risk factors for chronic diseases such as cardiovascular disease and type 2 diabetes. 6,7 Impaired vascular function may contribute to increased cardiovascular disease risk, as atherosclerosis begins in childhood and endothelial dysfunction has been identified as an early event contributing to the development of atherosclerosis.…”

Exercise and Vascular Function in Child Obesity: A Meta-Analysis

CONTEXT: Conduit artery flow-mediated dilation (FMD) is a noninvasive index of preclinical atherosclerosis in humans. Exercise interventions can improve FMD in both healthy and clinical populations.OBJECTIVE: This systematic review and meta-analysis aimed to summarize the effect of exercise training on FMD in overweight and obese children and adolescents as well as investigate the role of cardiorespiratory fitness (peak oxygen consumption [VO 2peak ]) on effects observed.DATA SOURCES: PubMed, Medline, Embase, and Cinahl databases were searched from the earliest available date to February 2015.STUDY SELECTION: Studies of children and/or adolescents who were overweight or obese were included.DATA EXTRACTION: Standardized data extraction forms were used for patient and intervention characteristics, control/comparator groups, and key outcomes. Procedural quality of the studies was assessed using a modified version of the Physiotherapy Evidence Base Database scale. RESULTS:A meta-analysis involving 219 participants compared the mean difference of preversus postintervention vascular function (FMD) and VO 2peak between an exercise training intervention and a control condition. There was a significantly greater improvement in FMD (mean difference 1.54%, P , .05) and VO 2peak (mean difference 3.64 mL/kg/min, P , .05) after exercise training compared with controls.LIMITATIONS: Given the diversity of exercise prescriptions, participant characteristics, and FMD measurement protocols, varying FMD effect size was noted between trials.CONCLUSIONS: Exercise training improves vascular function in overweight and obese children, as indicated by enhanced FMD. Further research is required to establish the optimum exercise program for maintenance of healthy vascular function in this at-risk pediatric population.
