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 .

OBJECTIVE To investigate the occurrence and association of arterial hypertension with several lifestyle variables . METHODS Transversal population -based study with a r and om sample of students ( 7 to 14 years of age ) of public and private schools . Variables investigated were nutritional status , blood pressure , and lifestyle ( tobacco use , alcohol intake , physical activity and eating habits ) . RESULTS Out of the 3,169 schoolchildren assessed , 5.0 % had arterial hypertension and 6.2 % had normal-high blood pressure . Classification by gender shows boys 6.4 % and girls 6.0 % with normal-high blood pressure , and boys 4.3 % and girls 5.7 % with arterial hypertension . Body mass index ( BMI ) measurements identified 16.0 % excess weight students , 4.9 % of whom were obese . A significant association ( p = 0.01 ) between arterial hypertension and excess weight was observed . Among the students participating in the study , 11.6 % did not attend physical education classes and 37.8 % had sedentary leisure habits . Twenty students ( 0.6 % ) were smokers and 32.7 % had already experimented with alcohol . None of these variables showed statistical significance as to blood pressure values and nutritional status . CONCLUSION In light of the findings in this study which show schoolchildren with a higher than expected frequency of mean blood pressure and BMI values , associated with a lifestyle that tends to favour the development of cardiovascular diseases , we felt led to propose interventional measures focused on the school as an agent of change and capable of conveying information to family units . This possibility encourages us to propose that schools be partners in promoting health
