Abstract
BACKGROUND: Individuals of all ages are becoming more health conscious, and wearable technology devices (eg, Fitbit and Apple Watch) are becoming increasingly popular in encouraging healthy lifestyles. OBJECTIVE: The aim of this paper was to explore how consumers use wearable devices. METHODS: A retrospective review was done on the top-rated verified purchase reviews of the Fitbit One posted on Amazon.com between January 2014 and August 2018. Relevant themes were identified by qualitatively analyzing open-ended reviews. RESULTS: On retrieval, there were 9369 reviews with 7706 positive reviews and 1663 critical reviews. The top 100 positive and top 100 critical comments were subsequently analyzed. Four major themes were identified: sleep hygiene ("charts when you actually fall asleep, when you wake up during the night, when you're restless--and gives you a cumulative time of "actual sleep" as well as weekly averages."), motivation ("25 lbs lost after 8 months - best motivator ever!"), accountability ("platform to connect with people you know and set little competitions or group…fun accountability if you set a goal with a friend/family."), and discretion ("able to be clipped to my bra without being seen."). Alternatively, negative reviewers felt that the wearable device's various tracking functions, specifically steps and sleep, were inaccurate. CONCLUSIONS: Wearable technology devices are an affordable, user-friendly application that can support all individuals throughout their everyday lives and potentially be implemented into medical surveillance, noninvasive medical care, and mobile health and wellness monitoring. This study is the first to explore wearable technology device use among consumers, and further studies are needed to examine the limitless possibilities of wearable devices in health care.
