有有限的研究记录客观测量的体力活动（PA）和久坐时间（ST）在南亚（SA）的妇女，没有发表的证据的有效性自我报告方法评估PA/ST在SA。本研究的目的是通过混合方法比较加速度计和国际体力活动问卷（IPAQ）得出的PA/ST之间的SA妇女在英国（UK）。一百四十SA妇女穿着加速度计连续七天，一个子样本（n = 50）完成了IPAQ-SF（IPAQ-SF）和简短的结构化面试。全样本的加速度计代谢当量（MET）每周分钟数（min/wk）、中度至剧烈体力活动（MVPA）（平均值+/- SD）为793.94（+/- 519.44），平均加速度计ST wk为530.20（+/- 81.76）。IPAQ-SF衍生的MVPA（MET min/wk）为636.80（+/- 2113.56），平均ST wk为315.31（+/- 266.98）。加速度计和IPAQ-SF评估的MVPA（r = -.119，p = .579）和ST（r = -.140，p = .229）之间的Pearson相关性不显著。从访谈中合成的主要主题包括无法回忆起坐着的时间和有限的MVPA的现实生活中的例子的一般知识。这些结果表明，IPAQ-SF可能无法准确测量PA/ST在英国SA妇女。这些发现得到了定性证据的支持，表明通过本问卷评估的PA/ST的解释和回忆存在几个问题。
There is limited research documenting objectively measured physical activity (PA) and sedentary time (ST) in South Asian (SA) women, with no published evidence of the validity of self-report methods for assessment of PA/ST in SA. The purpose of this study was to compare accelerometer- and International Physical Activity Questionnaire (IPAQ)-derived PA/ST among SA women in the United Kingdom (UK) via a mixed-methods approach. One hundred and forty SA women wore an accelerometer for seven consecutive days; a sub-sample (n = 50) completed the IPAQ-Short Form (IPAQ-SF) and a brief structured interview. Accelerometer-derived metabolic equivalent (MET) minutes per week (min/wk) moderate-to-vigorous physical activity (MVPA) (mean +/- SD) for the full sample was 793.94 (+/- 519.44) and mean accelerometer-derived ST wk was 530.20 (+/- 81.76). IPAQ-SF-derived MVPA (MET min/wk) was 636.80 (+/- 2113.56) and mean ST wk was 315.31 (+/- 266.98). Pearson correlations were not significant between accelerometer- and IPAQ-SF-assessed MVPA (r = -.119, p = .579) and ST (r = -.140, p = .229). Major themes synthesised from interviews included inability to recall sitting time and limited general knowledge of real-life examples of MVPA. These results suggest that the IPAQ-SF may not accurately measure PA/ST in the UK SA women. These findings are supported by qualitative evidence indicating several issues with interpretation and recall of PA/ST as assessed via this questionnaire.
