Physical activity and incident hypertension in black and white adults: the Atherosclerosis Risk in Communities Study.
BACKGROUND The epidemiologic observation that physical activity reduces the risk for hypertension has only been made for white men who self-reported hypertension . This study examined physical activity and clinical ly determined incident hypertension in black and white men and women of the Atherosclerosis Risk in Communities ( ARIC ) Study . METHODS ARIC is a population -based prospect i ve study with four U.S. clinic centers . The present analyses included 7,459 black and white adults 45 - 65 years of age . Hypertension  ( systolic/diastolic blood pressure > /= 140/90 mm Hg ) was defined by blood pressure measured by a r and om-zero device or medication use .  Physical activity  was assessed with the  Baecke question  naire . RESULTS After adjustment for age , baseline blood pressure , ARIC center , education , body mass index , waist-hip ratio , parental history of hypertension , cigarette smoking , alcohol consumption , and diet , white men in the highest quartile of leisure activity ( primarily cycling and walking ) had a 34 % lower odds of developing hypertension over 6 years compared to the least active ( OR = 0.66 , 95 % CI = 0.47 - 0.94 ; P for quartile trend = 0.01 ) . Baseline activity was not associated with incident hypertension  in white women or blacks . CONCLUSIONS Leisure-time physical activity reduces the odds of  hypertension  in middle-aged white men . Additional studies in women and blacks are needed
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
