To investigate how attitudes and beliefs about exercise relate to physical activity behavior in older adults with knee pain attributable to osteoarthritis (OA).
We conducted secondary data analyses of a randomized controlled trial of exercise interventions (ISRCTN: 93634563). Participants were adults ≥45 years old with knee pain attributable to OA (n = 514). Crude and adjusted cross-sectional and longitudinal associations between baseline Self-Efficacy for Exercise (SEE), Positive Outcome Expectations for Exercise (POEE), Negative Outcome Expectations for Exercise scores, and physical activity level, at baseline, 3 months, and 6 months (measured by self-report using the Physical Activity Scale for the Elderly [PASE]), and important increases in physical activity level (from baseline to 6-month followup) were investigated using multiple linear and logistic regression.
Cross-sectional associations were found between SEE and PASE scores (β = 4.14 [95% confidence interval (95% CI) 0.26, 8.03]) and POEE and PASE scores (β = 16.71 [95% CI 1.87, 31.55]), adjusted for sociodemographic and clinical covariates. Longitudinal associations were found between baseline SEE and PASE scores at 3 months (β = 4.95 [95% CI 1.02, 8.87]) and 6 months β = 3.71 (0.26, 7.16), and baseline POEE and PASE at 3 months (β = 34.55 [95% CI 20.13, 48.97]) and 6 months (β = 25.74 [95% CI 11.99, 39.49]), adjusted for baseline PASE score and intervention arm. However, no significant associations with important increases in physical activity level were found.
Greater exercise self-efficacy and more positive exercise outcome expectations were associated with higher current and future physical activity levels. These may be targets for interventions aimed at increasing physical activity.
探讨对运动的态度和信念如何与膝关节骨关节炎（OA）所致膝关节疼痛的老年患者的身体活动行为相关。
我们对运动干预的随机对照试验（ISRCTN: 93634563）进行了二次数据分析。参与者为年龄≥45 岁且膝关节疼痛归因于 OA（n=514）的成年人。使用老年人身体活动量表（PASE）进行自我报告，在基线、3 个月和 6 个月时，分别评估基线自我效能感（SEE）、运动的积极预期（POEE）、运动的消极预期得分与身体活动水平之间的横断面和纵向关系，并评估身体活动水平的重要增加（从基线到 6 个月随访）。采用多元线性和逻辑回归进行分析。
在调整了社会人口统计学和临床协变量后，发现 SEE 与 PASE 评分之间存在横断面关联（β=4.14 [95%置信区间（95%CI）0.26, 8.03]）和 POEE 与 PASE 评分之间存在横断面关联（β=16.71 [95%CI 1.87, 31.55]）。还发现基线 SEE 与 3 个月（β=4.95 [95%CI 1.02, 8.87]）和 6 个月（β=3.71 [0.26, 7.16]）时的 PASE 评分之间存在纵向关联，以及基线 POEE 与 3 个月（β=34.55 [95%CI 20.13, 48.97]）和 6 个月（β=25.74 [95%CI 11.99, 39.49]）时的 PASE 评分之间存在纵向关联，调整了基线 PASE 评分和干预臂。然而，与身体活动水平的重要增加没有发现显著关联。
更高的运动自我效能和更积极的运动预期结果与更高的当前和未来身体活动水平相关。这些可能是旨在增加身体活动的干预措施的目标。
