Abstract

BACKGROUND

Little attention has been paid to within-person daily associations among light physical activity (PA), moderate-to-vigorous physical activity (MVPA), and sedentary behavior (SB) with subsequent bodily pain and fatigue. Daily reports of pain and fatigue are less likely to be affected by recall bias and to conflate days of high and low pain/ fatigue into one overall score.

PURPOSE

The purpose of this study was to examine daily within-person associations between pain, fatigue, and physical health and ascertain whether such associations are moderated by individual differences in these variables.

METHODS

Participants were 63 community-living older adults (female n = 43, mean age = 70.98 years). Questionnaires measured typical levels of PA, SB, bodily pain, fatigue, and physical health. Subsequently, on a daily basis over a 1-week period, participants' levels of light PA, MVPA, and SB were measured using accelerometers. Participants completed a questionnaire rating their pain and fatigue at the end of each day.

RESULTS

Multilevel modeling revealed positive within-person associations between daily light PA, dailyMVPA, and pain, as well as negative within-person associations between daily SB and pain. For individuals with higher typical levels of fatigue, there was a negative association between daily light PA, MVPA, and fatigue. For individuals with better levels of physical health, there was also a negative association between daily MVPA and fatigue. For those with higher typical levels of fatigue and better levels of physical health, there was a positive association between daily SB and fatigue. No such interaction effects were found between high levels of typical pain and PA or SB.

CONCLUSIONS

Our findings indicate that efforts to promote daily PA in older adults might be more effective for those who report high typical levels of fatigue and physical health, compared to those who report high levels of daily physical pain.

摘要

背景

人们很少关注个体日常的轻体力活动（PA）、中高强度体力活动（MVPA）和久坐行为（SB）与随后的身体疼痛和疲劳之间的内在联系。与疲劳/疼痛的回忆偏差相比，每日报告的疼痛和疲劳不太可能受到影响，也不太可能将高/低疼痛/疲劳日混为一个整体评分。

目的

本研究旨在检验疼痛、疲劳和身体健康的个体内在关联，并确定这些变量的个体差异是否会调节这些关联。

方法

参与者为 63 名居住在社区的老年人（女性 n=43，平均年龄 70.98 岁）。问卷调查测量了参与者的典型 PA、SB、身体疼痛、疲劳和身体健康水平。随后，在一周的时间内，参与者使用加速度计每天测量轻 PA、MVPA 和 SB 的水平。参与者每天结束时完成一份问卷，评估他们的疼痛和疲劳程度。

结果

多层次模型显示，每日轻 PA、MVPA 与疼痛之间存在正内在关联，每日 SB 与疼痛之间存在负内在关联。对于典型疲劳水平较高的个体，每日轻 PA、MVPA 与疲劳之间存在负关联。对于身体健康水平较好的个体，每日 MVPA 与疲劳之间也存在负关联。对于典型疲劳水平较高和身体健康水平较好的个体，每日 SB 与疲劳之间存在正关联。在典型高水平疼痛和 PA 或 SB 之间没有发现这种交互效应。
