Several studies also indicated a high prevalence of prehypertension and hypertension in Portuguese adolescents Besides, our results that were obtained in the sample of schoolchildren could be partly explained by a high prevalence of hypertension in Lithuanian adult population [ 18 ]. The prevalence of overweight and obesity was higher in the current sample Researchers indicated that the prevalence of overweight and obesity among the studied youth in Lithuania were 5.
However, the prevalence of overweight and obesity in our study sample was lower than that in most other studies [ 89111216 ], but was higher than in several others [ 1429 ] that investigated risk factors associated with high BP among children and adolescents.
The findings of the current study indicating that overweight and obesity among adolescents were significantly associated with prehypertension are consistent with the results of other previously published studies [ 814 ].
However, some studies presented different results. One study in China found overweight and obesity to be significantly associated with prehypertension in boys, but not in girls [ 12 ].
Another study in Canada reported no significant associations between overweight and prehypertension among girls and across both sexes combined, except among boys; however, obesity was associated with prehypertension across all sex groups [ 9 ], the latter result being similar to ours.
However, one study did not find any significant association between overweight and hypertension among girls in the population of children in rural Canada [ 9 ]. Regarding abdominal obesity, the findings of the present study are not easily comparable with other previous studies because there are differences in sample size, the age of the investigated children and adolescents, the methodology, the cut-off criteria for defining abdominal obesity, and potential confounders e.

There is a problem concerning the definition of abdominal obesity among children and adolescents in research studies of this field. The associations between abdominal obesity and high BP among children or adolescents were established by several researchers [ 12162933 ]; however, these studies yielded inconsistent findings.
In contrast, Guo et al. Morton explains how wide-ranging the effects of obesity are. Use our BMI calculator to help you determine whether or not you are considered obese.
If you are obese, or have one or more risk factors for obesity, our physicians can help. In cases of severe obesity, surgery may be an option. Learn more about obesity treatments at Stanford. Health Effects of Obesity Obesity has a far-ranging negative effect on health. Each year obesity-related conditions cost over billion dollars and cause an estimatedpremature deaths in the US.

The health effects associated with obesity include, but are not limited to, the following: These results are presented in Table 3. Discussion The recognition that the presence and severity of atherosclerotic lesions are positively and significantly linked with cardiovascular risk factors present in childhood and adolescence2,31,32 and that such lesions are more often found from the age of it is important to conduct studies showing the prevalence, association and correlation of these factors in populations, as the case of this study.
This study found the adverse impact of excess body fat present in the sample in Although this study mentions the limitations in using the TSF due to the possibility of large intra and inter-observer variation and cost of equipmentthe World Health Organization directs its use to the diagnosis of obesity in children and adolescents, provided that the measure is used by a professional with specific training, as the case of this research In our study, we observed a significant association and correlation of BMI according to some authors, it identifies excess weight, but not necessarily excess fatTSF a marker of excess body fat and WC marker of central deposition of excess body fat among themselves and with blood pressure.
The differences between the methods are expected and reflect the individual characteristics of body fat distribution, but show that in clinical practice, at least two of these parameters will be probably necessary to expand the diagnostic scope of obesity.

Thus, we can emphasize, as in other studies, that the investigation of obesity in children and adolescents requires the use of BMI associated with another anthropometric method to identify children who present a greater risk of obesity and its consequences.
These authors concluded that there was an increase in blood pressure in the last decade and that this outcome can be partly attributed to the increasing prevalence of excess body weight, also observed in the same population. In Brazil, several studies have demonstrated similar results.
Ribeiro et al21, by assessing 1, students aged 6 to 18 have shown that individuals with high BMI are 3. Monego and Jardim35, by studying 3, schoolchildren, found a significant association between overweight and hypertension. Using the TSF, more commonly accepted as a marker of excess body fat, Silva and Lopes20, by assessing 1, students aged 7 to 12, identified a significant association between excess body fat and high blood pressure systolic and diastolic. Ribeiro et al21, using the sum of skin folds including the TSFshowed demonstrated a greater risk of high blood pressure in those with excess body fat.
Rosa et al23, also using the same parameter30, evaluated students aged 12 to 17 and demonstrated a significant association between hypertension and high WC.
Despite a strong correlation between WC, BMI and other anthropometric parameters, Sarni et al22, by assessing 65 preschool children with mean age of 5. These authors explained this result as a function of age and limited sample size, and we agree with such explanation.
As in adults, a combination of factors, such as overactivity of the sympathetic nervous system, insulin resistance and abnormalities in vascular structure and function, seem to contribute to the occurrence of hypertension associated with obesity in children and adolescents In children, primary hypertension is important for several reasons. Firstly, because it determines damage in target organs. Left ventricular hypertrophy is the most important clinical evidence of this complication Secondly because there is a trend over life of the persistence of high blood pressure in childhood and adolescence, which makes this behavior tracking one of the main markers of hypertension early in adult life3,4, Finally, because of the frequent association, in the same individual, of high blood pressure with other cardiovascular risk factors17,26,27,36, which triggers the early appearance and the rapid development of atherosclerotic lesions37,38, which determine the most frequent cause of death in Brazil1 and in several other parts of the world.
These are the reasons why it is necessary to encourage studies such as this one. Firstly, to enable that, in Brazil, the magnitude of the problem related to the presence of cardiovascular risk factors for atherosclerotic disease among children be identified.High Blood Pressure - Hypertension - Nucleus Health
Besides this, to make it possible to expand the number of proposals for early prevention of cardiovascular disease in Brazil Potential Conflict of Interest No potential conflict of interest relevant to this article was reported.
