Abstract

Objective: To examine agreement between concurrently worn ActivPAL (AP) and ActiGraph (AG) accelerometers in college students.

Methods: Thirty-six students (age 21.6 ± 2.4 years) wore AP and AG accelerometers for 4-8 days. Agreement was assessed using paired t-tests, intraclass correlation coefficients, mean absolute percentage error, Bland-Altman analyses, and ±10% equivalence testing.

Results: AG wear time averaged 15.5 ± 1.0 h/day. Compared with AP, AG measured 698 ± 805 fewer steps/day, 69 ± 70 more sedentary min/day, and 112 ± 57 fewer zero cadence min/day. Peak 1-min and 30-min cadence demonstrated strong agreement and met equivalence criteria. Daily steps showed agreement but did not meet equivalence; sedentary and zero cadence time demonstrated the weakest agreement.

Conclusions: Device agreement varied by metric, emphasizing the importance of measurement selection in college student research. Reliable step-based measurement may support research needed to develop step recommendations and physical activity promotion strategies for college students.

在一所住宿大学的大学生中同时佩戴的ActivPAL和ActiGraph加速度计的身体活动指标的一致性。

目的：探讨大学生同时佩戴actipal （AP）和ActiGraph （AG）加速度计的一致性。方法：36名学生（年龄21.6±2.4岁）佩戴AP和AG加速度计4 ~ 8天。采用配对t检验、类内相关系数、平均绝对百分比误差、Bland-Altman分析和±10%等效检验来评估一致性。结果：AG磨损时间平均为15.5±1.0 h/d。与AP相比，AG少走698±805步/天，多坐69±70分钟/天，少112±57分钟/天。1分钟和30分钟的峰值节奏表现出强烈的一致性，并符合等效标准。每日步数显示出一致性，但不符合等效性；久坐不动和零节奏时间表现出最弱的一致性。结论：仪器的一致性随测量的不同而不同，强调了测量选择在大学生研究中的重要性。可靠的以步数为基础的测量可能支持研究需要制定步数建议和体育活动促进策略的大学生。

期刊介绍： Binge drinking, campus violence, eating disorders, sexual harassment: Today"s college students face challenges their parents never imagined. The Journal of American College Health, the only scholarly publication devoted entirely to college students" health, focuses on these issues, as well as use of tobacco and other drugs, sexual habits, psychological problems, and guns on campus, as well as the students... Published in cooperation with the American College Health Association, the Journal of American College Health is a must read for physicians, nurses, health educators, and administrators who are involved with students every day.
