Effects of Internet behavioral counseling on weight loss in adults at risk for type 2 diabetes: a randomized trial.
CONTEXT Weight loss programs on the Internet appear promising for short-term weight loss but have not been studied for weight loss in individuals at risk of type 2 diabetes ; thus , the longer-term efficacy is unknown . OBJECTIVE To compare the effects of an Internet weight loss program alone vs with the addition of behavioral counseling via e-mail provided for 1 year to individuals at risk of type 2 diabetes . DESIGN , SETTING , AND PARTICIPANTS A single-center r and omized controlled trial conducted from September 2001 to September 2002 in Providence , RI , of 92 overweight adults whose mean ( SD ) age was 48.5 ( 9.4 ) years and body mass index , 33.1 ( 3.8 ) . INTERVENTIONS Participants were r and omized to a basic Internet ( n = 46 ) or to an Internet plus behavioral e-counseling program ( n = 46 ) . Both groups received 1 face-to-face counseling session and the same core Internet programs and were instructed to su bmi t weekly weights . Participants in e-counseling su bmi tted calorie and exercise information and received weekly e-mail behavioral counseling and feedback from a counselor . MAIN OUTCOME MEASURES Measured weight and waist circumference at 0 and 12 months . RESULTS Intent-to-treat analyses showed the behavioral e-counseling group lost more mean ( SD ) weight at 12 months than the basic Internet group ( -4.4 [ 6.2 ] vs -2.0 [ 5.7 ] kg ; P = .04 ) , and had greater decreases in percentage of initial body weight ( 4.8 % vs 2.2 % ; P = .03 ) , body mass index ( -1.6 [ 2.2 ] vs -0.8 [ 2.1 ] ; P = .03 ) , and waist circumference ( -7.2 [ 7.5 ] vs -4.4 [ 5.7 ] cm ; P = .05 ) . CONCLUSION Adding e-mail counseling to a basic Internet weight loss intervention program significantly improved weight loss in adults at risk of diabetes
