The Use of Small Electronic Devices and Health: Feasibility of Interventions for a Forthcoming Crossover Design

Background Modern lifestyle is heavily affected by technology such as smartphones, tablets, and other small computers; yet it remains unclear how our health well-being are the heavy use of these devices. Objective This feasibility study aims to test two different interventions an experimental protocol for a forthcoming large-scale community-based get estimates parameters sample size calculation. The aim investigate effect (1) wearable tracking device on aerobic capacity (VO2max/kg) (2) restricting media total sleep time. Methods Twenty healthy participants were included equipped with wrist-worn physical activity sleep. Participants allocated either group, which was instructed support exercise, or silent remove switch off all electronic devices in bedroom (except device). intervention lasted approximately 4 weeks. Data collected blood pressure, submaximal cycle ergometer test, self-reported use, compliance using device. Results All wore 95.8% (SD 4.4%) group increased from 30.38 8.98) 32.1 8.71) mL/kg/min (t=–2.31, P=.046) decreased their systolic pressure 126.5 15.8) mm Hg 121.8 11.7) (t=2.72, P=.02). prolonged time offline before bedtime 18.1 19.4) minutes 27.2 17.3) (t=–2.94, Conclusions feasible conduct. willing wear wrist restrict thereby reduce use. Our results also suggest that accompanied noteworthy benefits. We outline necessary adjustments study.
