Multiple behavior changes in diet and activity: a randomized controlled trial using mobile technology.
BACKGROUND Many patients exhibit multiple chronic disease risk behaviors . Research provides little information about advice that can maximize simultaneous health behavior changes . METHODS To test which combination of diet and activity advice maximizes healthy change , we r and omized 204 adults with elevated saturated fat and low fruit and vegetable intake , high sedentary leisure time , and low physical activity to 1 of 4 treatments :  increase fruit/vegetable intake and physical activity , decrease fat and sedentary leisure , decrease fat and increase physical activity , and increase fruit/vegetable intake and decrease sedentary leisure .  Treatments provided 3 weeks of remote coaching supported by mobile decision support technology and financial incentives . During treatment , incentives were contingent on using the mobile device to self-monitor and attain behavioral targets ; during follow-up , incentives were contingent only on recording . The outcome was st and ardized , composite improvement on the 4 diet and activity behaviors at the end of treatment and at 5-month follow-up . RESULTS Of the 204 individuals r and omized , 200 ( 98.0 % ) completed follow-up . The increase fruits/vegetables and decrease sedentary leisure treatments improved more than the other 3 treatments ( P < .001 ) . Specifically , daily fruit/vegetable intake increased from 1.2 servings to 5.5 servings , sedentary leisure decreased from 219.2 minutes to 89.3 minutes , and saturated fat decreased from 12.0 % to 9.5 % of calories consumed . Differences between treatment groups were maintained through follow-up . Traditional dieting ( decrease fat and increase physical activity ) improved less than the other 3 treatments ( P < .001 ) . CONCLUSIONS Remote coaching supported by mobile technology and financial incentives holds promise to improve diet and activity . Targeting fruits/vegetables and sedentary leisure together maximizes overall adoption and maintenance of multiple healthy behavior changes
