Examine changes in sleep duration by 3 behavioral phenotypes during a workplace wellness program with overweight and obese adults.
Secondary analysis of a randomized clinical trial.
Remotely monitored intervention conducted across the United States.
553 participants with a body mass index ≥25.
Participants were randomized to 1 of 4 study arms: control, gamification with support, gamification with collaboration, and gamification with competition to increase their physical activity. All participants were issued a wrist-worn wearable device to record their daily physical activity and sleep duration.
The primary outcome was change in daily sleep duration from baseline during the 24 week intervention and follow-up period by study arm within behavioral phenotype class.
Linear mixed effects regression.
Participants who had a phenotype of less physically active and less social at baseline, in the gamification with collaboration arm, significantly increased their sleep duration during the intervention period (30.2 minutes [95% CI 6.9, 53.5], = 0.01), compared to the control arm. There were no changes in sleep duration among participants who were more extroverted and motivated or participants who were less motivated and at-risk.
Changes in sleep during a physical activity intervention varied by behavioral phenotype. Behavioral phenotypes may help to precisely identify who is likely to improve sleep duration during a physical activity intervention.
在一项针对超重和肥胖成年人的职场健康计划中，研究3种行为表型的睡眠时间变化。
对一项随机临床试验的二次分析。
在美国各地进行的远程监测干预。
553名体重指数≥25的参与者。
参与者被随机分配到4个研究组之一：对照组、有支持的游戏化组、有协作的游戏化组和有竞争的游戏化组，以增加他们的身体活动。所有参与者都佩戴了腕式可穿戴设备来记录他们的日常身体活动和睡眠时间。
主要结局是在24周的干预和随访期间，按行为表型类别，各研究组的每日睡眠时间相对于基线的变化。
线性混合效应回归。
与对照组相比，在基线时身体活动较少且社交较少的表型参与者，在有协作的游戏化组中，干预期间的睡眠时间显著增加（30.2分钟[95%CI 6.9, 53.5]，P = 0.01）。性格更外向且积极性更高的参与者或积极性较低且有风险的参与者的睡眠时间没有变化。
体育活动干预期间的睡眠变化因行为表型而异。行为表型可能有助于精确识别在体育活动干预期间哪些人可能会延长睡眠时间。
