引言本研究评估了使用可穿戴传感器对高收入家庭的极端热量对人的特定影响。重点是对体育活动的深入和纵向评估，并随着人的特定环境温度的上升而睡眠。方法这项研究在2022年8月和9月在得克萨斯州休斯敦的低收入和主要黑人社区中招募了30名参与者。每个参与者都在其手腕上戴上一个加速度计，该加速度计记录了特定于人的环境温度，久坐的行为，身体活动强度， （低至中度至有剧烈的），在14天内24小时睡眠效率。混合效应模型用于分析体育活动，睡眠和特定于人的环境温度之间的关联。结果主要发现包括增加久坐的时间，与人级环境温度升高的睡眠障碍以及AC的缓解作用。结论极大地影响体育锻炼和睡眠。负面后果对于在低收入颜色社区中使用AC使用有限的人尤其重要。在炎热的日子里居住在室内温度较高的地方会导致各种不良健康结果，包括加速认知能力下降，癌症风险更高和社会隔离。
Introduction This study assesses the person-specific impact of extreme heat on low-income households using wearable sensors. The focus is on the intensive and longitudinal assessment of physical activity and sleep with the rising person-specific ambient temperature. Methods This study recruited 30 participants in a low-income and predominantly Black community in Houston, Texas in August and September of 2022. Each participant wore on his/her wrist an accelerometer that recorded person-specific ambient temperature, sedentary behavior, physical activity intensity (low and moderate to vigorous), and sleep efficiency 24 h over 14 days. Mixed effects models were used to analyze associations among physical activity, sleep, and person-specific ambient temperature. Results The main findings include increased sedentary time, sleep impairment with the rise of person-level ambient temperature, and the mitigating role of AC. Conclusions Extreme heat negatively affects physical activity and sleep. The negative consequences are especially critical for those with limited use of AC in lower-income neighborhoods of color. Staying home with a high indoor temperature during hot days can lead to various adverse health outcomes including accelerated cognitive decline, higher cancer risk, and social isolation.
