Relationship of Physical Activity and Body Mass Index to the Risk of Hypertension: A Prospective Study in Finland
Abstract — Prospect i ve studies on physical activity in relation to the risk for hypertension are scant , particularly in women . This study aim ed at finding out whether regular physical activity can reduce the risk of hypertension in both men and women , and in subjects with and without overweight . We prospect ively followed 8302 Finnish men and 9139 women aged 25 to 64 years without a history of antihypertensive drug use , coronary heart disease , stroke , and heart failure at baseline . Both single and joint associations of physical activity and body mass index with the risk of hypertension were examined using Cox proportional hazard models . During a mean followup of 11 years , there were 1600 incident cases of drug-treated hypertension . Multivariate-adjusted hazards ratios of hypertension associated with light , moderate , and high physical activity were 1.00 , 0.63 , and 0.59 in men ( Ptrend<0.001 ) , and 1.00 , 0.82 , and 0.71 in women ( Ptrend=0.005 ) , respectively . This association persisted both in subjects who were overweight and in those who were not . Multivariate-adjusted hazards ratios of hypertension based at different levels of body mass index ( < 25 , 25 to 29.9 , and ≥30 ) were 1.00 , 1.18 , and 1.66 for men ( Ptrend<0.001 ) , and 1.00 , 1.24 , and 1.32 for women ( Ptrend=0.007 ) , respectively . Further adjustment for baseline systolic blood pressure did not affect the protective effect associated with physical activity , but it weakened markedly the association between body mass index and hypertension . The present study indicates that regular physical activity and weight control  can reduce the risk of hypertension . The protective effect of physical activity was observed in both sexes regardless of the level of obesity
Overall , the current literature supports clearly the dose-response relationship between physical activity and the seven chronic conditions identified .
Moreover , higher levels of physical activity reduce the risk for premature all-cause mortality .
The current Canadian guidelines appear to be appropriate to reduce the risk for the seven chronic conditions identified above and all-cause mortality
