Is there a benefit to patients using wearable devices such as Fitbit or Health Apps on Mobiles?: A systematic review.

Abstract

BACKGROUND\nWearable devices have become a standard healthcare intervention with emerging healthcare technologies. These devices are designed to promote healthy behaviors and decrease risk for chronic disease like cardiovascular disease and diabetes. The purpose of this study was to provide evidence of the benefit of wearable devices in chronic disease outcomes among adults.\n\n\nMETHODS\nSystematic search of PubMed, Web of Science, WHO international clinical trials registry platform, BMC ISRCTN registry and IEEE was performed based upon the PRISMA guideline. Included articles were randomized controlled trials or quasi-experimental studies with health outcomes published in English up to October 2018. Studies focusing on adults were selected. Three investigators reviewed the selected publications and made agreement on final selection.\n\n\nRESULTS\nOut of total 550 publications extracted, six studies met the final criteria. There was little indication that wearable devices provide a benefit for health outcomes. Of the six studies examined, only one study showed a significant reduction for weight loss among participants who used wearable devices. No significant reduction was discovered in cholesterol or blood pressure. Among the six studies, only one study examined HbA1c and it showed a significant reduction in older patients with type 2 diabetes.\n\n\nCONCLUSION\nThe current literature evaluating wearable devices indicates little benefit of the devices on chronic disease health outcomes. Wearable devices play a role as a facilitator in motivating and accelerating physical activity but current data do not suggest other consistent health benefits.
