Abstract

BACKGROUND

Hispanic men have disproportionate rates of overweight and obesity compared with other racial and ethnic subpopulations. However, few weight loss interventions have been developed specifically for this high-risk group. Furthermore, the use of mobile health (mHealth) technologies to support lifestyle behavior changes in weight loss interventions for Hispanic men is largely untested.

OBJECTIVE

This single-arm pilot study examined the feasibility and acceptability of integrating mHealth technology into a 12-week gender- and culturally sensitive weight loss intervention (GCSWLI) for Hispanic men with overweight and obesity.

METHODS

A total of 18 Hispanic men (mean age 38, SD 10.9 years; mean BMI 34.3, SD 5.5 kg/m²; 10/18, 56% Spanish monolingual) received a GCSWLI, including weekly in-person individual sessions, a daily calorie goal, and prescription of ≥225 minutes of moderate-intensity physical activity per week. mHealth technology support included tailored SMS text messaging, behavior self-monitoring support using Fitbit Charge 2, and weight tracking using a Fitbit Aria Wi-Fi Smart Scale. Changes in weight from baseline to 12 weeks were estimated using a paired 2-tailed t test. Descriptive analyses characterized the use of Fitbit and smart scales. Semistructured interviews were conducted immediately after intervention to assess the participants' weight loss experiences and perspectives on mHealth technologies.

RESULTS

Of 18 participants, 16 (89%) completed the 12-week assessments; the overall attrition rate was 11.1%. The mean weight loss at week 12 was -4.7 kg (95% CI 7.1 to -2.4 kg; P<.001). Participants wore the Fitbit 71.58% (962/1344) of the intervention days and logged their body weight using the smart scale (410/1344, 30.51% of the intervention days). Participants identified barriers to the use of the technology, such as lack of technological literacy and unreliable internet access for the smart scale.

CONCLUSIONS

Although clinically significant weight loss was achieved by integrating mHealth technology into the GCSWLI, adherence to the prescribed use of technology was modest. Addressing barriers to the use of such technologies identified in our work may help to refine an mHealth intervention approach for Hispanic men.

摘要

背景

与其他种族和族裔亚人群相比，西班牙裔男性超重和肥胖的比例过高。然而，专门针对这一高风险群体开发的减肥干预措施很少。此外，在针对西班牙裔男性的减肥干预措施中，使用移动健康（mHealth）技术来支持生活方式行为改变在很大程度上尚未得到检验。

目的

这项单臂试点研究检验了将mHealth技术整合到一项针对超重和肥胖西班牙裔男性的为期12周的性别和文化敏感型减肥干预（GCSWLI）中的可行性和可接受性。

方法

共有18名西班牙裔男性（平均年龄38岁，标准差10.9岁；平均BMI 34.3，标准差5.5kg/m²；18人中有10人，56%为只会说西班牙语）接受了GCSWLI，包括每周一次的面对面个人辅导、每日卡路里目标以及每周≥225分钟中等强度体育活动的处方。mHealth技术支持包括量身定制的短信、使用Fitbit Charge 2进行行为自我监测支持以及使用Fitbit Aria Wi-Fi智能体重秤进行体重跟踪。使用配对双尾t检验估计从基线到12周的体重变化。描述性分析对Fitbit和智能体重秤的使用情况进行了描述。干预结束后立即进行半结构化访谈，以评估参与者的减肥经历以及对mHealth技术的看法。

结果

18名参与者中，16人（89%）完成了12周的评估；总体流失率为11.1%。第12周时平均体重减轻了-4.7kg（95%CI 7.1至-2.4kg；P<.001）。参与者在71.58%（962/1344）的干预日佩戴了Fitbit，并使用智能体重秤记录了体重（410/1344，占干预日的30.51%）。参与者指出了使用该技术的障碍，如缺乏技术素养以及智能体重秤的网络连接不可靠。
