The results suggest that despite the existence of hegemonic thinking to guide these relationships , BP and physical activity do not always have negative associations , and BP and obesity do not always have positive associations .
In the light of the importance of the impacts that obesity and physical activity may have on  blood pressure ( BP ) among adolescents , and the suggestion that abnormal pressure levels at young ages are maintained into more mature stages of these individuals ' lives , the scope of this study is to conduct a systematic review of the associations between obesity and BP and between physical activity and BP among adolescents .
Cardiovascular risk factors in children and adolescents living in an urban area of Southeast of Brazil: Ouro Preto Study
This study aims to identify risk factors for cardiovascular disorders in schoolchildren living in Ouro Preto City , Brazil . A cross-sectional study was carried out in a  population -based sampling of schoolchildren ( 6–14 years old ) , r and omly selected and stratified by the proportion of students according to age and gender in each schools of the city .  Biochemical , clinical and anthropometric variables as well as physical activity and family history were used in a logistic regression model for obesity or arterial hypertension . Out of 780 schoolchildren sample d , the risk of obesity was greater in subjects presenting high triglyceride and low high density lipoprotein-cholesterol levels , and those whose parents were obese , whilst the risk of hypertension was high in obese subjects and those who presented low birth weight . It was observed that 44.4 % of the schoolchildren were exposed to two or three cardiovascular disease ( CVD ) risk factors and 8.2 % were exposed to four or six factors . These findings should be considered in preventive measures to reduce the future risk for CVD among schoolchildren in Brazil
