Online home exercises represent opportunities to increase physical activity levels. However, high dropout rates are commonly reported in such programmes. This study aimed to investigate the predictors of dropping out from an online home exercise programme.
A total of 760 individuals from nine countries participated in this 8-week prospective cohort study derived from a randomised controlled trial. The participants were randomised into "4-week live-streamed exercise ->4-week recorded exercise" or "4-week no intervention ->4-week recorded exercise" group. Repeated measurements using weekly questionnaires were performed. Pain intensity, disability, mental well-being score, exercise motivation, sleep quality, impulsiveness/anxiety, and physical activity level were analysed.
A total of 53.8% (95% confidence interval [CI] 50.3%-57.3%) participants dropped out from the programme. The identified predictors of dropping out from the programme were: well-being (odds ratio [OR] 0.94, 95% CI 0.91-0.97) and disability (OR 1.02, 95% CI 1.002-1.04) at baseline considering the first 4 weeks; age (0.98; 95% CI 0.96-1.00) and baseline well-being (0.93; 95% CI 0.89-0.97) considering the entire follow-up (8 weeks); exercise motivation (0.92; 95% CI 0.87 to 0.97) and general impulsiveness/anxiety (1.04; 95% CI 1.01-1.07) repeated measured over time.
About half of the participants dropped out from the online home exercise programme. Higher baseline scores in mental well-being and age predicted a reduction in dropping out. Higher baseline disability predicted an increase in dropping out. During the follow-up, higher exercise motivation was associated with a reduction in dropping out, and higher impulsiveness and anxiety were associated with an increase in dropping out.
在线居家锻炼为提高身体活动水平提供了契机。然而，此类项目中普遍存在高辍学率的情况。本研究旨在调查在线居家锻炼项目辍学的预测因素。
来自9个国家的760名个体参与了这项源自随机对照试验的为期8周的前瞻性队列研究。参与者被随机分为“4周直播锻炼→4周录像锻炼”组或“4周无干预→4周录像锻炼”组。使用每周问卷进行重复测量。分析疼痛强度、残疾情况、心理健康评分、锻炼动机、睡眠质量、冲动性/焦虑以及身体活动水平。
共有53.8%（95%置信区间[CI] 50.3%-57.3%）的参与者退出了该项目。确定的项目辍学预测因素为：在前4周时，基线时的幸福感（优势比[OR] 0.94，95% CI 0.91-0.97）和残疾情况（OR 1.02，95% CI 1.002-1.04）；在整个随访期（8周）内，年龄（0.98；95% CI 0.96-1.00）和基线幸福感（0.93；95% CI 0.89-0.97）；随时间重复测量的锻炼动机（0.92；95% CI 0.87至0.97）和一般冲动性/焦虑（1.04；95% CI 1.01-1.07）。
约一半的参与者退出了在线居家锻炼项目。较高的基线心理健康评分和年龄预示着辍学率降低。较高的基线残疾情况预示着辍学率升高。在随访期间，较高的锻炼动机与辍学率降低相关，而较高的冲动性和焦虑与辍学率升高相关。
