The goal of this study was to address the absence of evidence-based weight-control programs developed for use with Deaf people.
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. The study enrolled 104 Deaf adults aged 40 to 70 years with BMI of 25 to 45 from community settings in Rochester, New York, and randomized participants to immediate intervention (n = 48) or 1-year delayed intervention (n = 56). The delayed intervention serves as a no-intervention comparison until the trial midpoint. The study 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).
At 6 months, the difference in mean weight change for the immediate-intervention arm versus the delayed-intervention arm (no intervention yet) was -3.4 kg (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.
DWW, a community-engaged, culturally appropriate, and language-accessible behavioral weight loss intervention, was successful with Deaf ASL users.
本研究旨在解决缺乏针对聋人开发的基于循证的体重控制项目这一问题。
基于社区的参与式研究为聋人健康明智（DWW）试验和干预措施的设计提供了信息。DWW 主要通过改变饮食和锻炼来关注健康的生活方式和体重。该研究招募了来自纽约罗切斯特社区环境中的 104 名年龄在 40 至 70 岁之间、BMI 为 25 至 45 的聋人成年人，并将参与者随机分为立即干预组（n=48）或延迟 1 年干预组（n=56）。延迟干预组在试验中点之前作为无干预对照。该研究从基线到 24 个月共收集了五次数据（每 6 个月一次）。所有 DWW 干预负责人和参与者都是使用美国手语（ASL）的聋人。
在 6 个月时，立即干预组与延迟干预组（尚未进行干预）之间的平均体重变化差异为-3.4kg（多重调整后 p=0.0424；95%置信区间：-6.1 至-0.8kg）。立即组中大多数（61.6%）人减去了基线体重的≥5%，而尚未进行干预组中只有 18.1%（p<0.001）。参与者参与指标包括 16 次课程中的 11 次（69%）的平均出勤率，92%的人完成了 24 个月的数据收集。
DWW 是一项社区参与、文化适宜且语言可及的行为减肥干预措施，对使用美国手语的聋人有效。
