ABSTRACT
@#Objective To investigate the relationship between objectively determined daily physical activities and blood pressure levels in Chinese adults. Methods 125 individuals who participated in routine physical examinations of health were investigated, include systolic pressure, diastolic pressure, pulse pressure, and daily walking steps determined by pedometer. Results The daily walking steps correlated negatively with systolic pressure（Male r=－0.613, P＜0.01; Female r=－0.430, P＜0.01） and diastolic pressure (male r=－0.686, P＜0.01; female r=－0.388,P＜0.01). Daily walking steps of normotensive, pre-hypertensive, and hypertensive groups were (18249±6066) step/d, (10395±3788) step/d, (6232±3967) step/d for males, and (12564±6927) step/d, (11458±5084) step/d, (6153±3569) step/d for females respectively （P＜0.05）. Conclusion The daily physical activity determined by walking steps correlated negatively with blood pressure in Chinese adults. Hypertensives often live in low active or sedentary lifestyle. Active lifestyle （≥10000 step/d） may help keep normal blood pressure for Chinese adults.
