Abstract

BACKGROUND

Black adults in the United States experience disproportionately high rates of tobacco- and obesity-related diseases, driven in part by disparities in smoking cessation and physical activity. Smartphone-based interventions with financial incentives offer a scalable solution to address these health disparities.

OBJECTIVE

This study aims to assess the feasibility and preliminary efficacy of a mobile health intervention that provides financial incentives for smoking cessation and physical activity among Black adults.

METHODS

A total of 60 Black adults who smoke (≥5 cigarettes/d) and are insufficiently physically active (engaging in <150 min of weekly moderate-intensity physical activity) will be randomly assigned to either HealthyCells intervention (incentives for smoking abstinence only) or HealthyCells+ intervention (incentives for both smoking abstinence and daily step counts). Participants will use study-provided smartphones, smartwatches, and carbon monoxide monitors for 9 weeks (1 wk prequit date through 8 wk postquit date). Feasibility will be evaluated based on recruitment rates, retention, and engagement. The primary outcomes include carbon monoxide-verified, 7-day smoking abstinence at 8 weeks postquit date and changes in average daily step count. Feasibility benchmarks include a recruitment rate of ≥5 participants per month, a retention rate of ≥75%, and a smoking abstinence rate of ≥20% at 8 weeks postquit date. Expected increases in physical activity include a net gain of 500 to 1500 steps per day compared to baseline.

RESULTS

Recruitment is expected to begin in February 2025 and conclude by September 2025, with data analysis completed by October 2025.

CONCLUSIONS

This study will evaluate the feasibility of a culturally tailored mobile health intervention combining financial incentives for smoking cessation and physical activity promotion. Findings will inform the design of larger-scale trials to address health disparities through scalable, technology-based approaches.

摘要

背景

美国黑人成年人患烟草相关疾病和肥胖相关疾病的比例过高，部分原因是戒烟和体育活动方面的差异。基于智能手机并提供经济激励的干预措施为解决这些健康差异提供了一种可扩展的解决方案。

目的

本研究旨在评估一项移动健康干预措施的可行性和初步疗效，该干预措施为黑人成年人的戒烟和体育活动提供经济激励。

方法

总共60名吸烟（≥5支/天）且体育活动不足（每周进行中度强度体育活动的时间<150分钟）的黑人成年人将被随机分配到HealthyCells干预组（仅针对戒烟的激励措施）或HealthyCells+干预组（针对戒烟和每日步数的激励措施）。参与者将使用研究提供的智能手机、智能手表和一氧化碳监测器，为期9周（从戒烟前1周直至戒烟后8周）。将根据招募率、留存率和参与度评估可行性。主要结局包括在戒烟后8周经一氧化碳验证的7天戒烟情况以及平均每日步数的变化。可行性基准包括每月招募率≥5名参与者、留存率≥75%以及在戒烟后8周戒烟率≥20%。预计体育活动的增加包括与基线相比每天净增加500至1500步。
