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 .
Variations of adolescent blood pressure by multifactorial analysis in an urban slum of Kolkata.
To find out the factors responsible for variations of  adolescent blood pressure  , a  community-based cross-sectional study was undertaken among 1081 adolescents , aged 10 - 19 years , selected by simple r and om sampling in an urban slum of Kolkata , Chetla in 2003 - 04 . Age , educational status , additional ghee/butter intake with diet , family history of hypertension , weight , height and body mass index were found to be associated with blood pressure in unifactorial analysis , hence these variables were considered for multifactorial analysis . All these independent variables were correlated with both systolic and diastolic blood pressure except additional ghee/butter intake with food . In stepwise multiple regression analysis , age , education , family history of hypertension , weight , height and body mass index contributed 64.6 % of the total variation of systolic blood pressure , where weight alone contributed to 62.6 % while 35.4 % of variations remained unexplained . In case of diastolic blood pressure , 56.8 % of the total variations were due to age , education , family history of hypertension , weight , height and body mass index , out of which weight alone contributed 56 % while remaining 43.2 % of total variations remained unexplained . Since single most important predictor of blood pressure was weight , regular aerobic physical activity , dietary modification , behavioral changes and health education are recommended for weight reduction and prevention of obesity
