本文报告了“智能步行”（Smart Walk）的研究结果：这是一项为期8个月、针对患有肥胖症的非裔美国女性的、具有文化针对性且通过智能手机实施的身体活动（PA）干预的随机试点试验。60名参与者（年龄范围为24 - 49岁；体重指数范围为30 - 58 kg/m²）被随机分配到智能步行干预组（n = 30）或健康对照干预组（n = 30）。结果支持了该干预措施的可接受性和可行性，这体现在参与者的留存率（4个月时为85%，8个月时为78%）、智能步行应用程序的使用以及干预满意度上（即100%完成干预的身体活动参与者[n = 24]表示他们会将其推荐给朋友）。智能步行参与者还报告称，中等至剧烈身体活动有更大幅度的增加（4个月时组间变化差异[b] = 43.3分钟/周；p = 0.018；科恩效应量d = 0.69；8个月时b = 56.6分钟/周；p = 0.046；d = 0.63），并且在心肺适能（b = 1.67 mL/kg/min；d = 0.40）、收缩压（b = -3.33 mmHg；d = 0.22）、舒张压（b = -4.28 mmHg；d = 0.37）和脉搏波速度（b = -0.46 m/s；d = 0.33）方面从基线到4个月显示出具有临床相关性的改善，尽管在统计学上不显著（p值>0.05）。8个月的心脏代谢结果呈现出类似趋势，但由于新冠疫情的限制，缺失数据率较高（45% - 53%）。总体而言，研究结果表明在可接受性和可行性方面取得了良好的结果，同时也突出了未来研究中需要改进的关键领域。
This article reports the results of Smart Walk: a randomized pilot trial of an 8-month culturally tailored, smartphone-delivered physical activity (PA) intervention for African American women with obesity. Sixty participants (age range = 24–49 years; BMI range = 30–58 kg/m2) were randomized to the Smart Walk intervention (n = 30) or a wellness comparison intervention (n = 30). Results supported the acceptability and feasibility of the intervention, as demonstrated by participant retention (85% at 4 months and 78% at 8 months), Smart Walk app use, and intervention satisfaction (i.e., 100% of PA participants completing the intervention [n = 24] reported they would recommend it to friend). Smart Walk participants also reported greater increases in moderate-to-vigorous PA (4-month between-arm difference in change [b] = 43.3 min/week; p = 0.018; Cohen’s d = 0.69; 8-month b = 56.6 min/week; p = 0.046; d = 0.63) and demonstrated clinically relevant, although not statistically significant (p-values > 0.05), baseline to 4 months improvements in cardiorespiratory fitness (b = 1.67 mL/kg/min; d = 0.40), systolic blood pressure (b = −3.33 mmHg; d = 0.22), diastolic blood pressure (b = −4.28 mmHg; d = 0.37), and pulse wave velocity (b = −0.46 m/s; d = 0.33). Eight-month cardiometabolic outcomes followed similar trends, but had high rates of missing data (45–53%) due to COVID-19 restrictions. Collectively, findings demonstrated favorable outcomes for acceptability and feasibility, while also highlighting key areas for refinement in future research.
