A recent study published in the American Journal of Preventive Medicine aimed to evaluate the efficacy of using the Fitbit tracker and website as a physical intervention tool for postmenopausal women. Fifty-one women were included in the study; they were randomized to either a 16-week web-based self-monitoring intervention group or a control group. The group that received the Fitbit was associated with greater physical activity at 16-weeks; 100% of the group reported liking the tracker.5 The researchers conclude that using mHealth technologies, such as fitness trackers, with behavior modification can help improve physical activity interventions.
