People incarcerated have limited access to physical activity and there are challenges to accurately measure their physical activity in jail settings. We aimed to (1) determine the feasibility of time use diaries to measure physical activity and sedentary time among people incarcerated in jail and (2) estimate time spent in physical activity and sedentary behaviors, overall and by gender and job assignment.
In July 2023, we recruited women and men from two housing units at Yavapai County Detention Facility, a county jail in Camp Verde, Arizona. Participants were asked to complete a four-day time use diary, documenting activities in 10-minute increments. Participants provided feedback about the diary during listening sessions after the four-day period. Feasibility was measured as the proportion of people recruited who participated and the proportion of completed and returned diaries. Activities documented in the diaries were linked to the Compendium of Physical Activities to determine intensity and duration of physical activity and sedentary behavior. Average daily time spent in physical activity and sedentary behavior was calculated for each participant.
Of the 24 women and 41 men recruited, 24 (100%) women and 40 (97.5%) men agreed to participate in the study. All diaries were returned. Most (82.8%) participants completed all four days in the diary. Participants were enthusiastic about filling out the diaries because they helped pass the time and felt the work would further knowledge and wellbeing in jails. Participants made concrete recommendations including altering the diary format to allow for additional detail about their time in jail. Participants spent on average 571 minutes sedentary, 79 minutes in light activity, and 60 minutes in moderate activity per day. Women spent 66 more minutes per day engaged in light activities compared to men. Women with job assignments spent 179 less minutes in sedentary behavior and 245 more minutes in moderate activity compared to women who did not have a job assignment.
Time use diaries are a feasible and appropriate way to measure physical activity and sedentary behavior among people incarcerated in jail.
被监禁的人进行体育活动的机会有限，并且在监狱环境中准确测量他们的体育活动存在挑战。我们旨在：（1）确定使用时间使用日记来测量监狱中被监禁人员的体育活动和久坐时间的可行性；（2）估计总体上以及按性别和工作分配情况，在体育活动和久坐行为上花费的时间。
2023年7月，我们从亚利桑那州弗德营地的雅瓦派县拘留所的两个住房单元招募了男性和女性。参与者被要求完成一份为期四天的时间使用日记，以10分钟为增量记录活动。在四天期限结束后的听取意见会议期间，参与者提供了关于日记的反馈。可行性通过招募的参与者中实际参与的比例以及完成并返回的日记的比例来衡量。日记中记录的活动与《体育活动纲要》相关联，以确定体育活动和久坐行为的强度和持续时间。计算每个参与者每天在体育活动和久坐行为上花费的平均时间。
在招募的24名女性和41名男性中，24名（100%）女性和40名（97.5%）男性同意参与研究。所有日记都被返还。大多数（82.8%）参与者完成了日记中的所有四天记录。参与者热衷于填写日记，因为这有助于打发时间，并且觉得这项工作将增进对监狱情况的了解并促进监狱中的健康。参与者提出了具体建议，包括改变日记格式，以便能更详细地记录他们在监狱中的时间。参与者平均每天久坐571分钟，进行轻度活动79分钟，进行中度活动60分钟。与男性相比，女性每天进行轻度活动的时间多66分钟。有工作分配的女性比没有工作分配的女性久坐时间少179分钟，中度活动时间多245分钟。
时间使用日记是测量监狱中被监禁人员的体育活动和久坐行为的一种可行且合适的方法。
