Our aim was to examine wireless physical activity monitor (WPAM) use and its associations with contextual factors (age, highest education level, social support and mental health) among adults living with HIV engaged in a community-based exercise (CBE) intervention.
Quantitative, longitudinal, observational study.
Toronto YMCA, Ontario, Canada.
Eighty adults living with HIV who initiated the CBE intervention.
Participants received a WPAM to track physical activity during a 25-week CBE intervention involving thrice-weekly exercise, supervised weekly (phase 1) and a 32-week follow-up involving thrice-weekly exercise with no supervision (phase 2), completed in December 2018.
Uptake was measured as participants who consented to WPAM use at initation of the intervention. Usage was defined as the proportion of days each participant had greater than 0 steps out of the total number of days in the study. We measured contextual factors using a baseline demographic questionnaire (age, highest education level), and median scores from the bimonthly administered Medical Outcomes Study-Social Support Scale and Patient Health Questionnaire (mental health), where higher scores indicated greater social support and mental health concerns, respectively. We calculated Spearman correlations between WPAM usage and contextual factors.
Seventy-six of 80 participants (95%) consented to WPAM use. In phase 1, 66% of participants (n=76) and in phase 2, 61% of participants (n=64) used the WPAM at least 1 day. In phase 1, median WPAM usage was 50% (25th, 75th percentile: 0%, 87%; n=76) of days enrolled and in phase 2, 23% (0%, 76%; n=64) of days. Correlation coefficients with WPAM usage ranged from weak for age (ρ=0.26) and mental health scores (ρ=-0.25) to no correlation (highest education level, social support).
Most adults living with HIV consented to WPAM use, however, usage declined over time from phase 1 to phase 2. Future implementation of WPAMs should consider factors to promote sustained usage by adults living with HIV.

我们旨在研究无线活动监测器（WPAM）在参与社区为基础的锻炼（CBE）干预的艾滋病毒感染者中的使用情况及其与背景因素（年龄、最高教育水平、社会支持和心理健康）之间的关系。
定量、纵向、观察性研究。
加拿大安大略省多伦多基督教青年会。
80 名开始 CBE 干预的艾滋病毒感染者。
参与者在 25 周的 CBE 干预中接受了 WPAM，以跟踪他们的身体活动，其中包括每周三次的锻炼、每周一次的监督（第 1 阶段）和 32 周的无监督随访（第 2 阶段），该研究于 2018 年 12 月完成。
80 名参与者中有 76 名（95%）同意使用 WPAM。在第 1 阶段，66%的参与者（n=76）和第 2 阶段，61%的参与者（n=64）至少使用 WPAM 1 天。在第 1 阶段，WPAM 的中位使用率为 50%（第 25 和第 75 百分位数：0%，87%；n=76），而在第 2 阶段，使用率为 23%（0%，76%；n=64）。与 WPAM 使用相关的相关系数从年龄（ρ=0.26）和心理健康评分（ρ=-0.25）的弱相关到无相关性（最高教育水平、社会支持）不等。
大多数艾滋病毒感染者同意使用 WPAM，但从第 1 阶段到第 2 阶段，使用率逐渐下降。未来实施 WPAM 时，应考虑促进艾滋病毒感染者持续使用的因素。
