开发一个健身追踪器（FitSight），鼓励孩子们增加户外活动的时间。通过估计儿童的光照水平，评估该跟踪器的佩戴模式和户外时间模式。FitSight健身追踪器的开发涉及两个组件的设计：（1）带有定制FitSight手表应用程序（应用程序）的智能手表，用于记录佩戴者暴露于的即时光照度水平，以及（2）配套的智能手机应用程序，通过蓝牙通信将智能手表记录的户外时间传输到智能手机。从23名新加坡儿童（平均值±标准差年龄：9.2 ± 1.4岁）中收集了7天内智能手表佩戴模式和跟踪器记录的每日光照度水平数据。关于跟踪器的反馈来自14位家长，使用三级评级量表：非常差/差/好。在14位家长中，93%的人认为完整的“FitSight健身追踪器”很好，64%的人认为其可穿戴性很好。23名儿童中有61%在所有学习日都戴着手表（即，0个非穿戴日），26%的儿童有1个非穿戴日，4.5%的儿童分别有3、4和5个非穿戴日。平均而言，儿童在工作日和周末分别在大于1000勒克斯的光照水平下度过约1小时和1.3小时（60 ± 46 vs. 79 ± 53分钟，P = 0.19）。每天室外“喷射”（光照度水平>1000 lux）的平均次数为8 ± 3次喷射，喷射持续时间为34 ± 32分钟。FitSight追踪器以其新颖的功能可以激励儿童增加户外时间，并在补充社区户外计划以预防近视方面发挥重要作用。如果开发出的非侵入性、可穿戴、基于智能手表的健身追踪器FitSight能促进儿童白天的户外活动，那么它将有利于解决近视的流行问题。
To develop a fitness tracker (FitSight) to encourage children to increase time spent outdoors. To evaluate the wear pattern for this tracker and outdoor time pattern by estimating light illumination levels among children. The development of the FitSight fitness tracker involved the designing of two components: (1) the smartwatch with custom-made FitSight watch application (app) to log the instant light illuminance levels the wearer is exposed to, and (2) a companion smartphone app that synchronizes the time outdoors recorded by the smartwatch to smartphone via Bluetooth communication. Smartwatch wear patterns and tracker-recorded daily light illuminance levels data were gathered over 7 days from 23 Singapore children (mean ± standard deviation age: 9.2 ± 1.4 years). Feedback about the tracker was obtained from 14 parents using a three-level rating scale: very poor/poor/good. Of the 14 parents, 93% rated the complete “FitSight fitness tracker” as good and 64% rated its wearability as good. While 61% of 23 children wore the watch on all study days (i.e., 0 nonwear days), 26% had 1 nonwear day, and 4.5% children each had 3, 4, and 5 nonwear days, respectively. On average, children spent approximately 1 hour in light levels greater than 1000 lux on weekdays and 1.3 hours on weekends (60 ± 46 vs. 79 ± 53 minutes, P = 0.19). Mean number of outdoor “spurts” (light illuminance levels >1000 lux) per day was 8 ± 3 spurts with spurt duration of 34 ± 32 minutes. The FitSight tracker with its novel features may motivate children to increase time outdoors and play an important role in supplementing community outdoor programs to prevent myopia. If the developed noninvasive, wearable, smartwatch-based fitness tracker, FitSight, promotes daytime outdoor activity among children, it will be beneficial in addressing the epidemic of myopia.
