Conclusion These studies provide preliminary evidence suggesting that EAMS can increase physical activity and decrease weight significantly , but their efficacy compared to other interventions has not yet been demonstrated .
Background Obesity is a growing global health concern that may lead to cardiovascular disease , type II diabetes , and cancer .
Several systematic review s have shown that technology is successful in combating obesity through increased physical activity , but there is no known review on interventions that use an electronic activity monitor system ( EAMS ) .
EAMSs are defined as a wearable device that objective ly measures lifestyle physical activity and can provide feedback , beyond the display of basic activity count information , via the monitor display or through a partnering application to elicit continual self-monitoring of activity behavior .
These devices improve upon st and ard pedometers because they have the ability to provide visual feedback on activity progression , verbal encouragement , and social comparison .
This systematic review aim ed to synthesize the efficacy and feasibility results of EAMSs within published physical activity interventions .
A smartphone-supported weight loss program: design of the ENGAGED randomized controlled trial
Background Obesity remains a major public health challenge , dem and ing cost-effective and scalable weight management programs . Delivering key treatment components via mobile technology offers a potential way to reduce expensive in-person contact , thereby lowering the cost and burden of intensive weight loss programs . The ENGAGED study is a theory-guided , r and omized controlled trial design ed to examine the feasibility and efficacy of an abbreviated smartphone-supported weight loss program . Methods / design Ninety-six obese adults ( BMI 30–39.9 kg/m2 ) will be r and omized to one of three treatment conditions : ( 1 ) st and ard behavioral weight loss ( STND ) , ( 2 ) technology-supported behavioral weight loss ( TECH ) ; or ( 3 ) self-guided behavioral weight loss ( SELF ) . All groups will aim to achieve a 7 % weight loss goal by reducing calorie and fat intake and progressively increasing moderate intensity physical activity to 175 minutes/week . STND and TECH will attend 8 group sessions and receive regular coaching calls during the first 6 months of the intervention ; SELF will receive the Group Lifestyle Balance Program DVD ’s and will not receive coaching calls . During months 1–6 , TECH will use a specially design ed smartphone application to monitor dietary intake , body weight , and objective ly measured physical activity ( obtained from a Blue-tooth enabled accelerometer ) . STND and SELF will self-monitor on paper diaries . Linear mixed modeling will be used to examine group differences on weight loss at months 3 , 6 , and 12 . Self-monitoring adherence and diet and activity goal attainment will be tested as mediators . Discussion ENGAGED is an innovative weight loss intervention that integrates theory with emerging mobile technologies . We hypothesize that TECH , as compared to STND and SELF , will result in greater weight loss by virtue of improved behavioral adherence and goal achievement . Trial registration
