本研究的目的是调查日常经历中久坐行为（SB）与瞬时情感之间的相互关系。招募居住在社区的中年妇女（N = 121；年龄范围 40-60 岁）进行为期 15 天的每日日记研究。当个人数字助理设备每天四次提示时，这些女性对自己的积极和消极影响进行评分，并佩戴加速计来客观评估 SB。估计多级模型来测试 SB 和情感的瞬时估计之间的并发和滞后关联。在控制星期几、潮热次数和加速计佩戴时间总分钟数的模型中，较高的并发积极影响与较少的久坐分钟数相关（β = -.31，p < .01）。滞后的积极情绪和消极情绪都不能预测稍后的 SB，但是，久坐时间越多，预测下一次的积极情绪就越低 (β = -.04, p < .01)。这些结果表明，SB 时时刻刻都会产生负面的情感后果。长期 SB 发作后积极情绪减少对随后的动机、行为或幸福结果的影响仍有待确定。
The purpose of this study was to investigate the reciprocal relationship between sedentary behavior (SB) and momentary affect in the context of daily experiences. Community-dwelling midlife women (N = 121; age range 40-60 years) were recruited for a 15-day daily diary study. The women rated their positive and negative affect when prompted on a personal digital assistant device four times per day and wore an accelerometer for objective assessment of SB. Multilevel models were estimated to test concurrent and lagged associations between momentary estimates of SB and affect. In models that controlled for day of week, number of hot flashes, and total minutes of accelerometer wear time, greater concurrent positive affect was associated with fewer minutes spent being sedentary (β = −.31, p < .01). Neither lagged positive nor negative affect predicted later SB, however, more sedentary minutes predicted lower positive affect at the next occasion (β = −.04, p < .01). These results suggest that SB has negative affective consequences from moment to moment. The implications of reduced positive affect following prolonged bouts of SB for subsequent motivational, behavioral, or wellbeing outcomes remain to be determined.
