HealthDay News — Health wearable devices are effective intervention tools/strategies for reducing body weight and BMI in individuals with overweight/obesity and chronic comorbidities, according to a review published online in the British Journal of Sports Medicine.

Daniel J. McDonough, from University of Minnesota in Minneapolis, and colleagues conducted a systematic literature review to identify randomized controlled trials evaluating health wearable-based interventions using two or more physical activity intervention arms/strategies.

Based on 31 included studies, researchers found that for body weight reduction in individuals with overweight/obesity and chronic comorbidities, accelerometer/pedometer-only and commercial health wearable-only intervention strategies were the most effective (vs 3 other treatments and a control condition). Multicomponent accelerometer/pedometer and commercial health wearable-only intervention strategies were the most effective for BMI reduction compared with the other 4 conditions.

“While research-grade step counters and accelerometers aren’t available to the public, commercial wearable fitness trackers are, and represent a practical option for people who are overweight/obese and who have weight-related conditions,” the researchers said in a statement.
