The aim of this article is to examine associations of self-reported physical activity (PA) and pedometer steps with health-related quality of life (HRQoL) among a population-based sample of older adults.
Adults ≥55 years (N = 1,296) were recruited through random-digit dialing and responded to a questionnaire via computer-assisted telephone interviewing methods. Questionnaires assessed demographic variables and validated measures of PA and HRQoL. Participants received a step pedometer and waist circumference tape measure via post.
Compared with participants in the low-step group (0-6,999 steps/day), participants in the high-step group (>10,000 steps/day) had significantly higher scores on mental health (Mdiff = 3.1, p < .001, confidence intervals [CI] = [1.8, 4.3]), physical health (Mdiff = 3.5, p < .001, CI = [2.2, 4.7]), and global health (Mdiff = 3.5, p < .001, CI = [2.3, 4.7]). Waist circumference and body mass index did not moderate any associations of pedometer steps and PA with HRQoL.
Older adults exceeding established step thresholds reported significantly higher HRQoL indices compared with those achieving lower thresholds.
本文旨在研究在一个基于人群的老年人样本中,自我报告的身体活动(PA)和计步器步数与健康相关生活质量(HRQoL)之间的关联。
通过随机数字拨号招募年龄≥55岁的成年人(N = 1296),并通过计算机辅助电话访谈方法对问卷进行回答。问卷评估了人口统计学变量以及经过验证的PA和HRQoL测量方法。参与者通过邮寄方式收到一个计步器和腰围卷尺。
与低步数组(0 - 6999步/天)的参与者相比,高步数组(>10000步/天)的参与者在心理健康(M差值 = 3.1,p <.001,置信区间[CI] = [1.8, 4.3])、身体健康(M差值 = 3.5,p <.001,CI = [2.2, 4.7])和总体健康(M差值 = 3.5,p <.001,CI = [2.3, 4.7])方面的得分显著更高。腰围和体重指数并未调节计步器步数和PA与HRQoL之间的任何关联。
与达到较低步数阈值的老年人相比,超过既定步数阈值的老年人报告了显著更高的HRQoL指数。
