Physical activity and sedentary behavior vary across the life span, and in very old people activity behavior can vary considerably over 24 h. A physical activity questionnaire adapted for this age group is lacking. This study was conducted to validate such a newly developed questionnaire suitable for use in very old people.
Is the International Physical Activity Questionnaire adapted for adults aged ≥ 80 years (IPAQ-E 80 +) a valid measure of physical activity in very old people?
Seventy-six participants (55.3% women) with a mean age of 84.4 ± 3.8 years wore accelerometers for ≥ 5 consecutive days, and completed the IPAQ-E 80 +. Spearman's rho and Bland-Altman plots were used to analyze the validity of IPAQ-E 80 + against accelerometer measures. Analyses were conducted for the separate items sitting, laying down at daytime and nighttime, walking, moderate to vigorous (MV) walking, and moderate to vigorous physical activity (MVPA), and the summary measures: total inactive time, sedentary time (i.e. lying down at daytime + sitting), total active time, and total MVPA + MV walking.
The IPAQ-E 80 + correlated with the accelerometer measures of total inactive- (r = 0.55, p < 0.001), sedentary- (r = 0.28, p = 0.015), walking- (r = 0.54 p < 0.001) and total active- (r = 0.60, p < 0.001) times, but not with measures of intensity of walking or physical activity; MV walking (r = 0.06, p = 0.58), MVPA (r = 0.17, p = 0.13).
In this study the IPAQ-E 80 + showed fair to substantial correlations with accelerometers, and it therefore seems able to rank very old people according to levels of PA (total inactive-, sedentary-, and total active time, and walking time). The IPAQ-E 80 + seems promising for use in studies investigating associations between activity behavior and health in this population. Further investigation is needed to determine whether the IPAQ-E 80 + can accurately measure PA intensity.
体力活动和久坐行为在整个生命周期中都有所不同，在非常年长的人群中，24 小时内的活动行为可能会有很大差异。目前还缺乏专门为这个年龄段设计的体力活动问卷。本研究旨在验证一种新开发的适用于非常年长人群的问卷的有效性。
适用于 80 岁及以上成年人（IPAQ-E 80+）的国际体力活动问卷（IPAQ）是否是评估非常年长人群体力活动的有效测量工具？
76 名参与者（55.3%为女性）的平均年龄为 84.4±3.8 岁，他们佩戴加速度计连续 5 天以上，并完成了 IPAQ-E 80+。采用 Spearman's rho 和 Bland-Altman 图分析 IPAQ-E 80+与加速度计测量值的有效性。分别对坐着、白天和夜间躺着、行走、中等到剧烈（MV）行走以及中等到剧烈体力活动（MVPA）的单项进行分析，并对总非活跃时间、久坐时间（即白天躺着+坐着）、总活跃时间和总 MVPA+MV 行走进行分析。
IPAQ-E 80+与加速度计测量的总非活跃时间（r=0.55，p<0.001）、久坐时间（r=0.28，p=0.015）、行走时间（r=0.54，p<0.001）和总活跃时间（r=0.60，p<0.001）呈正相关，但与行走或体力活动强度的测量值不相关；MV 行走（r=0.06，p=0.58）、MVPA（r=0.17，p=0.13）。
在这项研究中，IPAQ-E 80+与加速度计的相关性为中等至较大，因此它似乎能够根据 PA（总非活跃时间、久坐时间和总活跃时间，以及行走时间）水平对非常年长的人进行排名。IPAQ-E 80+似乎有望用于研究该人群中活动行为与健康之间的关联。需要进一步研究来确定 IPAQ-E 80+是否能够准确测量 PA 强度。
