本研究检验了国际身体活动长表中文版（IPAQ-LC）在中国老年人中的信度和效度，包括社区步行能力和社会经济地位（SES）对信度和效度的调节作用。 IPAQ-LC 由访谈员管理 (n = 96)，收集加速度计和 7 天步行日记数据 (n = 94)，并重新管理 IPAC-LC (N = 92)。总体上以及不同类型社区的所有身体活动 (PA) 指标的可靠性均可接受。来自高度步行社区的参与者在估计步行交通方面更可靠。来自低社会经济地位地区的参与者在估计休闲时间 PA 和坐姿方面不太可靠，但在估计与交通相关的步行方面更可靠。 IPAQ-LC 步行与轻度而非中等强度的基于加速度计的 PA 显着相关。它与 7 天步行日记有中度到强烈的相关性。数据表明步行节奏缓慢，可能是由于年龄、气候和地形的原因。研究结果表明，IPAQ-LC 的信度和效度在中国老年人中是可以接受的。
This study examined reliability and validity of the Chinese version of the International Physical Activity Questionnaire-Long Form (IPAQ-LC) in Chinese seniors, including moderating effects of neighborhood walkability and socioeconomic status (SES) on reliability and validity. The IPAQ-LC was interviewer-administered (n = 96), accelerometer and 7-day walk-diary data were collected (n = 94), and the IPAC-LC was readministered (N = 92). Acceptable reliability was found for all measures of physical activity (PA) overall and across different types of neighborhood. Participants from highly walkable neighborhoods were more reliable at estimating walking for transport. Participants from low-SES areas were less reliable at estimating leisure-time PA and sitting but more reliable at estimating transport-related walking. IPAQ-LC walking was significantly related to light-but not moderate-intensity accelerometry-based PA. It was moderately to strongly related to a 7-day diary of walking. The data imply slow-paced walking, probably due to age, climate, and terrain. The findings suggest that the IPAQ-LC's reliability and validity are acceptable in Chinese seniors.
