Abstract

BACKGROUND

Compared to those without vision impairments, adults with low vision have higher rates of obesity and face more barriers to participation in traditional weight loss programs.

OBJECTIVE

This pilot study examined the usability and helpfulness of an adaptive, evidence-based weight loss program for adults who are legally blind.

METHODS

The study was a remotely delivered, single-arm weight loss trial for adults who were legally blind with a body mass index (BMI) ≥ 25. At weeks 4 and 8, participants reported usability and helpfulness of program components using a five-point scale (0-4) with higher numbers indicating greater usability and helpfulness. Weight data were collected at baseline, week 4, and week 8 using a scale with cellular technology. The adaptive 8-week weight loss program included evidence-based lifestyle recommendations for diet, physical activity, and self-weighing. The program provided support through text messages, emails, and video-based problem-solving sessions.

RESULTS

Participants (N = 28) were aged 53.4 ± 10.2 years, 89.3% female, 35.7% Black, and 57.1% non-Hispanic White with an average BMI of 35.4 ± 8.8 kg/m. Most program components had a median score of 4 for usability and helpfulness except educational materials (helpfulness, median 3). Compared to baseline weight, participants had a weight loss of 2.2 ± 2.1% (p < .001) at week 4 and 3.6 ± 3.0% (p < .001) at week 8.

CONCLUSIONS

This study has provided evidence that an all-remote weight loss program can be a useable, helpful, and effective approach for adults who are legally blind. More work is needed to develop scalable, sustainable, and fully accessible evidence-based weight loss programs.

摘要

背景

与视力正常者相比，低视力成年人肥胖率更高，并且在参与传统减肥计划方面面临更多障碍。

目的

本研究旨在检验一种适应性、基于证据的减肥方案对视力受损成年人的可用性和有益性。

方法

本研究是一项针对肥胖成年人的远程减肥试验，参与者为法定盲人，体重指数（BMI）≥25。在第 4 周和第 8 周，参与者使用 5 分制（0-4 分）报告方案各组成部分的可用性和有益性，分数越高表示可用性和有益性越强。体重数据通过具有蜂窝技术的秤在基线、第 4 周和第 8 周进行收集。适应性 8 周减肥方案包括饮食、身体活动和自我称重等基于证据的生活方式建议。方案通过短信、电子邮件和基于视频的问题解决会议提供支持。

结果

参与者（N=28）年龄为 53.4±10.2 岁，女性占 89.3%，黑人占 35.7%，非西班牙裔白人占 57.1%，平均 BMI 为 35.4±8.8kg/m2。除教育材料（有益性，中位数 3 分）外，大多数方案组成部分的可用性和有益性中位数均为 4 分。与基线体重相比，参与者在第 4 周时体重下降了 2.2±2.1%（p<0.001），第 8 周时体重下降了 3.6±3.0%（p<0.001）。
