Low Levels of Usual Physical Activity Are Associated with Higher 24 h Blood Pressure in Type 2 Diabetes Mellitus in a Cross-Sectional Study

The aim of this study is to evaluate the association between usual physical activity and 24 h blood pressure (bp) profile in people with type 2 diabetes mellitus (dm). this is a cross-sectional study of 151 participants with type 2 dm. usual physical activity was assessed by step counting and self-reported questionnaire. bp was measured in office and by 24 h ambulatory bp monitoring (abpm; 24 h,daytime and nighttime). mean participant age was 61.1 ± 8.4 years,64% was women,and mean duration of diabetes was 14.3 ± 8.5 years. ninety-two percent of participants had hypertension,and office bp was 138 ± 18/78 ± 10 mmhg. inverse correlations were observed between step count and 24 h bp (systolic,r=-0.186; p=0.022),daytime bp (systolic,r=-0.198; p=0.015),and nighttime bp (pulse pressure,r=-0.190; p=0.019). people were categorized into tertiles of daily step count,and the 1st tertile had higher 24 h systolic bp,daytime systolic bp,daytime mean bp,and daytime systolic bp load than those in the other tertiles,even after adjusting for age and hba1c. participants with type 2 dm and low levels of physical activity exhibit higher 24 h and daytime systolic ambulatory bp values as compared with those who performed more steps per day,even after adjustments for confounding factors. © 2017 alessandra teixeira neto zucatti et al.
