<p>Wearable Technology To Reduce Sedentary Behavior And CVD Risk In Older Adults: A Pilot Randomized Clinical Trial</p>

Abstract

BackgroundPhysical exercise is associated with decreased cardiovascular disease (CVD) risk, but recent large-scale trials suggest that exercise alone is insufficient to reduce CVD events in high-risk older adults.PurposeThis pilot randomized clinical trial aimed to collect critical data on feasibility, safety, and protocol integrity necessary to design a fully powered randomized controlled trial (RCT) and evaluate the impact of combining structured exercise with an intervention designed to enhance non-exercise physical activity (EX+NEPA) compared to EX alone.MethodsForty participants aged ≥60 years with moderate-to-high risk of coronary heart disease events were randomly assigned to either the EX+NEPA or EX groups and followed for 20 weeks. Both groups underwent a twice-weekly, 8-week center-based exercise intervention with aerobic and resistance exercises. EX+NEPA group also received a wearable activity tracking device along with behavioral monitoring and feedback throughout the study. Study outcomes were evaluated at 8 and 20 weeks.ResultsData are presented as adjusted mean change of the differences over time with 95% confidence intervals at 20 weeks. Relative to EX, the change in steps/day at 20 weeks was 1994 (−40.27, 4028) higher for EX+NEPA. For sedentary time at close-out, the EX+NEPA group was −6.8 (−45.2, 31.6) min/day relative to EX. The between-group differences for systolic and diastolic blood pressure were −9.9 (−19.6, −0.3) and −1.8 (−6.9, 3.3) mmHg, respectively.ConclusionThe addition of wearable technology intervention appeared to positively influence daily activity patterns and changes in blood pressure – potentially improving risk factors for CVD. A fully powered randomized trial is needed to ultimately test this hypothesis.

Effect of eHealth to increase physical activity in healthy adults over 55 years: A systematic review and meta‐analysis

“…Nineteen studies (Figure 1) 27‐45 were identified totaling 4937 participants (excluded studies with reasons for exclusion are available in Table ). Studies were conducted in three continents: 12 in North America, six in Europe and one in Oceania, and published between 2005 and 2019.…”

Evaluating treatment-specific post-discharge quality-of-life and cost-effectiveness of TAVR and SAVR: Current practice & future directions

“…Their proposal differs from usual telemetry systems by allowing for out-of-hospital monitoring through leveraging automatic detection algorithms and continuous home-to-hospital data. This level of healthcare decentralization is still largely hypothetical; however, a recent pilot study evaluated the effects of wearable activity trackers on physical activity amongst elderly patients at higher risk of CVD [47] . An ongoing prospective study by Lorenzoni et al is currently in the process of using a commercial smartwatch to address the lack of recovery trajectory data for TAVR/SAVR patients [48] .…”

Impact of a Pilot Structured Mobile Technology Based Lifestyle Intervention for Patients with Nonalcoholic Fatty Liver Disease

“…Study staff provided each of the participants with personalized feedback on physical activity with tailored step count goals (10% increase per week with maximum increase of 800 steps per week to a maximum of 10,000 steps per week) and motivational messages via email. This physical activity prescription was based on the United States Preventive Services Task Force recommendations and protocols used in the general obesity and cardiovascular disease literature [ 10 , 11 ]. Patients with consecutive days without data recorded or with other signs of low Fitbit usage (days with minimal step counts) were contacted via email or phone to encourage increased use.…”

“…The design was based on a pre-existing study protocol that had been pilot-tested among individuals with cardiovascular disease and shown to be feasible and efficacious in that patient population. 10 All participants received a Fitbit Zip at enrollment to track step counts. Participants were to wear their FitBit every day during waking hours for the entire study.…”
