abstract

  • <strong></strong><p class="Pa7"><strong>Objective: </strong>We set out to determine if a primarily Internet-delivered behavioral weight loss intervention produced differ­ential weight loss in African American and non-Hispanic White women, and to identify possible mediators.</p><p class="Pa7"><strong>Design: </strong>Data for this analysis were from a randomized controlled trial, collected at baseline and 4-months.</p><p class="Pa7"><strong>Setting: </strong>The intervention included monthly face-to-face group sessions and an Internet component that participants were recom­mended to use at least once weekly.</p><p class="Pa7"><strong>Participants: </strong>We included overweight or obese African American and non-Hispanic White women (n=170), with at least weekly Internet access, who were able to attend group sessions.</p><p class="Pa7"><strong>Intervention: </strong>Monthly face-to-face group sessions were delivered in large or small groups. The Internet component included automated tailored feedback, self-monitor­ing tools, written lessons, video resources, problem solving, exercise action planning tools, and social support through message boards.</p><p class="Pa7"><strong>Main outcome measure: </strong>Multiple linear regression was used to evaluate race group differences in weight change.</p><p class="Pa7"><strong>Results: </strong>Non-Hispanic White women lost more weight than African American women (-5.03% vs.-2.39%, P=.0002). Greater website log-ins and higher change in Eating Behavior Inventory score in non-Hispanic White women partially mediated the race-weight loss relationship.</p><p class="Default"><strong>Conclusions: </strong>The weight loss disparity may be addressed through improved website engagement and adoption of weight control behaviors. <em></em></p><p class="Default"><em>Ethn Dis. </em>2018;28(1):43-48; doi:10.18865/ed.28.1.43.</p>
