Cross-Sectional and longitudinal associations of objectively-measured physical activity on blood pressure: evaluation in 37 countries

Abstract

Background: We examined the cross-sectional and longitudinal associations of objectively-measured physical activity (step counts) and blood pressure (BP) among adults spanning 37 countries.Methods: Across 37 countries, we used data from a pool of 9238 adult owners of Withings’ Pulse activity trackers, which measures steps taken each day, and Wireless Blood Pressure Monitor, which measures BP. Analyses were adjusted on age, sex, number of days where the tracker was worn, and number of BP measurements. Data was collected from 2009 to 2013.Results: Subjects had a mean ± standard deviation (SD) age of 51.6 ± 11.3 years and a body mass index (BMI) of 28.7±5.5 kg/m2. A 1-month increase of more than 3000 steps per day was associated with a decrease of systolic BP (SBP) and diastolic BP (DBP) among the obese (1.57mm Hg and 1.29 mm Hg respectively, both P<0.001) and the overweight population (0.79 mm Hg and 0.84 mm Hg respectively, both P≤0.001), but not in the normal weight population (P=0.60 and P=0.36 respectively).Conclusion: One-month increases in daily step counts was associated with a decrease of SBP and DBP in a large obese and overweight free living population.

The effects of acute exercise on episodic memory function among young university students: moderation considerations by biological sex

“…Regular participation in physical activity has many health benefits, including a reduced risk of diabetes, cardiovascular disease and premature mortality, 1-6 as well as enhancing psychological health. 7,8 As such, from a health promotion perspective, promotion of physical activity is of critical importance for living a healthy lifestyle.…”

Associations of Physical Activity Level and Variability With 6-Month Weight Change Among 26,935 Users of Connected Devices: Observational Real-Life Study

“…Customer data, including sex, age, number of steps per day, body weight, heart rate, and blood pressure, were provided by Withings and were collected between October 2009 and April 2016. Data were preprocessed before analysis, as we excluded some outliers from daily data on weight and steps with unlikely values as follows: (1) a lower threshold of 500 steps per day was used to denote valid days with daily step count data [ 27 , 28 ], but the application of this criterion did not result in any deletion of data as the minimum daily step value was 501 steps per day; (2) daily step values exceeding the 99 th percentile of the steps per day distribution were removed (99th percentile=22,414 steps/day; 151,937 measurements removed); and (3) weight values lower than 45 kg and above 200 kg were excluded (12,403 measurements removed). In addition, individuals were excluded if they did not (1) have at least two step measurements within the first and sixth 30-day period of activity tracker use (n=4733) and (2) have at least one weight measurement within the first 30-day period of activity tracker use and 6 months after (n=4173).…”

Embracing Change: Learnings From Implementing Multidimensional Digital Remote Monitoring in Oncology Patients at a District General Hospital During the COVID-19 Pandemic

“…We believe that a combination of offered devices will lead to the most comprehensive, individualized, and long-term engagement-likely in the form of watches and/or armbands, 41 rings, 42 transdermal patches, 43 or even integrated solutions using multiple dedicated sensors. 44,45 Our series informally gather the key staff members' opinion of efficiency. Although trial processes are inherently inefficient cited by the initial onboarding of patients, there was a general buy-in that optimizing this technique is a progressive step and dedicated nursing support has been funded to investigate streamlining a protocol.…”
