This study compared subjective and objective methods of measuring different categories of physical activity in non-depressed middle-aged subjects with normal cognitive function (NCF) and mild cognitive impairment (MCI). In total, 75 participants (NCF: = 48, MCI: = 27) were recruited and physical activity was assessed for seven days using the ActiGraph and the International Physical Activity Questionnaire (IPAQ). Anthropometric parameters, body compositions, resting metabolic rate, and energy expenditure were also assessed. ActiGraph data indicated that subjects with NCF were more active than MCI subjects. A comparison of the IPAQ and the ActiGraph data revealed a significant correlation between these methods for total (r = 0.3315, < 0.01) and moderate (r = 0.3896, < 0.01) physical activity in the total population and moderate activity (r = 0.2893, < 0.05) within the NCF group. No associations between these methods were found within the MCI group. Independent predictors of subjectively evaluated total physical activity were alcohol consumption ( = 0.0358) and socio-professional status ( = 0.0288), while weight ( = 0.0285) and the Montreal Cognitive Assessment results ( = 0.0309) were independent predictors of objectively measured physical activity. In conclusion, the long version of IPAQ is a more reliable tool to assess PA in subjects with NCF than those with MCI. More studies are needed to confirm this finding.
本研究比较了非抑郁中年受试者中不同类别的身体活动的主观和客观测量方法，这些受试者具有正常认知功能（NCF）和轻度认知障碍（MCI）。共招募了 75 名参与者（NCF：= 48，MCI：= 27），并使用 ActiGraph 和国际体力活动问卷（IPAQ）对其进行了为期七天的身体活动评估。还评估了人体测量参数、身体成分、静息代谢率和能量消耗。ActiGraph 数据表明，NCF 受试者比 MCI 受试者更活跃。IPAQ 和 ActiGraph 数据的比较表明，这些方法在总人群中（r = 0.3315，< 0.01）和中等强度（r = 0.3896，< 0.01）以及 NCF 组的中等强度活动（r = 0.2893，< 0.05）之间存在显著相关性。在 MCI 组中，这些方法之间没有相关性。主观评估的总身体活动的独立预测因子是饮酒（= 0.0358）和社会职业地位（= 0.0288），而客观测量的身体活动的独立预测因子是体重（= 0.0285）和蒙特利尔认知评估结果（= 0.0309）。总之，IPAQ 的长版本是评估 NCF 受试者 PA 的更可靠工具，而不是 MCI 受试者。需要更多的研究来证实这一发现。
