目的：研究人员根据体重指数（BMI）评估了计步器干预的有效性和步行行为的差异。参与者：290名大学生于2005年1月至2月完成了干预。方法：参与者每周佩戴计步器5天，持续12周，并完成评估人口统计学信息的问卷调查。作者计算了第16周和第12周的每日平均步数。然后，他们根据BMI将学生分为体重不足（UW），正常体重（NW）或超重/肥胖。作者使用重复测量方差分析对数据进行了分析。结果：平均每日步数在第1周至第6周（p <0.001）和第12周（p = 0.002）增加。UW参与者在每个时间点报告的步数最少，但只有与NW参与者相比时差异才显着（p = .03）。结论：这些结果支持计步器干预对增加大学生步行的有效性。应强调体重管理以外的健康益处，以最大限度地提高对所有学生的影响。
Objective: The researchers assessed the effectiveness of a pedometer intervention and differences in walking behaviors according to body mass index (BMI). Participants: Two hundred ninety college Students completed the intervention from January to February 2005. Methods: Participants wore pedometers 5 days per week for 12 weeks and completed questionnaires assessing demographic information. The authors calculated daily step averages for weeks I 6, and 12. They then classified Students as underweight (UW), normal weight (NW), or overweight/obese, by BMI. The authors analyzed data using repeated-measures analysis of variance. Results: The average number of daily steps increased front week 1 to week 6 (p < .001) and week 12 (p = .002). UW participants reported the fewest steps at each time point, but the difference was significant only when compared with NW participants (p = .03). Conclusions: These results Support the effectiveness of a pedometer intervention to increase walking in college students. Health benefits other than weight management should be emphasized to maximize the effects for all students.
