Web-based weight management programs in an integrated health care setting : a randomized , controlled trial . OBJECTIVE To assess the efficacy of a Web-based tailored behavioral weight management program compared with Web-based information-only weight management materials . RESEARCH METHODS AND PROCEDURES Participants , 2862 eligible overweight and obese ( BMI = 27 to 40 kg/m2 ) members from four regions of Kaiser Permanente 's integrated health care delivery system , were randomized to receive either a tailored expert system or information-only Web-based weight management materials . Weight change and program satisfaction were assessed by self-report through an Internet-based survey at 3- and 6-month follow-up periods . RESULTS Significantly greater weight loss at follow-up was found among participants assigned to the tailored expert system than among those assigned to the information-only condition . Subjects in the tailored expert system lost a mean of 3 +/- 0.3 % of their baseline weight , whereas subjects in the information-only condition lost a mean of 1.2 +/- 0.4 % ( p < 0.0004 ) . Participants were also more likely to report that the tailored expert system was personally relevant , helpful , and easy to understand . Notably , 36 % of enrollees were African-American , with enrollment rates higher than the general proportion of African Americans in any of the study regions . DISCUSSION The results of this large , randomized control trial show the potential benefit of the Web-based tailored expert system for weight management compared with a Web-based information-only weight management program .
