Conclusion This review indicates that current research on activity monitoring devices may be overstated due to the variability in adherence .
Results showed that physical activity tracking in women and in young adults have been understudied
Background Activity monitoring devices are currently being used to facilitate and monitor physical activity .
No prior review has examined adherence to the use of activity monitoring devices amongst adults with cardiovascular disease .
Use of Consumer Wearable Devices to Promote Physical Activity: A Review of Health Intervention Studies
Background Although many wearable devices for monitoring and tracking physical activity are available to consumers , relatively few research studies have been conducted to determine their efficacy in promoting health . Methods In this article , data on the use of consumer wearable devices in promoting healthy behaviors  are summarized based upon bibliographic search es in PubMed and Psychology and Behavioral Sciences Collection with relevant search terms through September 2016 . Results A total of 274 articles were identified in the bibliographic search es . By screening abstract s or full-text articles , six pre/post test trials and seven r and omized controlled trials were identified . In initial trials , consumer wearable devices have been shown to increase physical activity and help users lose weight . However , the number of studies completed to date is small and limited by small sample sizes , short study duration s , and uncertain generalizability of the findings . Conclusions Future studies should utilize r and omized controlled trial research design s , larger sample sizes , and longer study periods to better establish the efficacy of wearable devices in promoting physical activity . Additional research is needed to determine the feasibility and effectiveness of wearable devices in promoting physical activity and weight loss in community setting s including communities affected by health disparities . Studies focusing on children and adolescents are also needed
