This randomized controlled pilot trial tested the preliminary effect of a 24-week mHealth-facilitated, personalized intervention on physical activity (PA) and sleep in 21 community-dwelling older adults. The intervention included a personalized exercise prescription, training, goal setting, and financial incentives. mHealth strategies, including self-monitoring, motivational messages, activity reminders, and phone coaching, were used to facilitate PA participation. PA and sleep were measured using actigraphy and questionnaires at baseline and 8-, 16-, and 24-week visits. Participants in the intervention group had lower objective PA levels at 24 weeks than at 8 and 16 weeks, although levels of PA remained higher than at baseline. Compared with the control group, the intervention increased PA at 8, 16, and 24 weeks; improved subjective sleep quality at 16 and 24 weeks; and increased actigraphy-measured sleep duration and sleep efficiency at 24 weeks. mHealth PA interventions may benefit PA and sleep in older adults. Strategies for maintaining long-term PA behavioral changes are needed.
这项随机对照试验测试了一项为期24周、由移动健康辅助的个性化干预措施对21名社区居住的老年人身体活动（PA）和睡眠的初步影响。该干预措施包括个性化运动处方、训练、目标设定和经济激励。移动健康策略，包括自我监测、激励信息、活动提醒和电话指导，被用于促进PA参与。在基线以及第8、16和24周访视时，使用活动记录仪和问卷对PA和睡眠进行测量。干预组参与者在24周时的客观PA水平低于第8周和第16周，尽管PA水平仍高于基线。与对照组相比，干预措施在第8、16和24周增加了PA；在第16周和第24周改善了主观睡眠质量；在第24周增加了活动记录仪测量的睡眠时间和睡眠效率。移动健康PA干预措施可能有益于老年人的PA和睡眠。需要维持长期PA行为改变的策略。
