Description:Objective:
To address the absence of evidence-based weight control programs developed for use with Deaf people.
Methods:
Community-based participatory research informed the design of the Deaf Weight Wise (DWW) trial and intervention. DWW focuses primarily on healthy lifestyle and weight through change in diet and exercise. We enrolled 104 Deaf adults aged 40-70 years with a BMI of 25-45 from community settings in Rochester, NY, and randomized participants to immediate intervention (n=48) or one-year delayed intervention (n=56). The delayed intervention serves as a no-intervention comparison until the trial mid-point. We collected data five times (every 6 months) from baseline to 24-months. All DWW intervention leaders and participants are Deaf people who use American Sign Language (ASL).
Results:
At 6-months, the difference in mean weight change for the immediate intervention arm versus the delayed intervention arm (no intervention yet) was −3.4kg (multiplicity-adjusted p=0.0424; 95% CI: −6.1 to −0.8 kg). Most (61.6%) in the immediate arm lost ≥5% of baseline weight versus 18.1% in the no-intervention-yet arm (p<0.001). Participant engagement indicators include mean attendance of 11/16 sessions (69%), and 92% completed 24-month data collection.
Conclusion:
Deaf Weight Wise, a community-engaged, culturally-appropriate and language-accessible behavioral weight loss intervention was successful with Deaf ASL-users.
