Sardana M, Lin H, Zhang Y, et al. - This study was intended to evaluate the relationship between habitual physical activity and home BP. Researchers calculated the cross-sectional association between physical activity and average home BP using linear mixed effects models adjusting for age, gender, wear time, antihypertensive drug use, and familial structure. A total of 660 electronic Framingham Heart Study participants were examined (mean age 53 years, SD 9 years; 387 [58.6%] women; 602 [91.2%] White) who wore the smartwatch 5 or more hours per day for 30 or more days and transmitted three or more BP readings. It was shown that the higher daily habitual physical activity measured by a smartwatch was correlated with a moderate, but statistically significant, reduction in home BP in this community-based sample of adults. Moreover, variations in BMI among study participants accounted for the majority of the observed association.
