简要总结
The primary purpose of this study is to assess the efficacy of the mobile phone-based physical activity intervention on increasing physical activity compared to the control group.
详细描述
Physical inactivity is associated with increased risk of co-morbidity and premature mortality. Given the rapid growth of mobile phone technology and the increasing number of users, the investigators developed an interactive mobile phone-based physical activity intervention for sedentary women. The investigators propose to conduct a randomized, controlled trial to assess the efficacy of the mobile phone-based physical activity intervention on increasing physical activity over a 3-month period. 192 sedentary women will be randomized in a 2-to-1 ratio to a 3-month mobile phone-based physical activity intervention group or to a control group. To provide insight into how best to maximize the potential for sustained physical activity after completion of the 3-month program, women in the intervention group who complete the physical activity program will be further randomized into a 6-month maintenance intervention-PLUS program (pedometer plus mobile phone diary) or to a 6-month maintenance intervention-REGULAR program (pedometer only). Unlike a conventional maintenance follow-up in which all subjects continue in their respective randomization arms, re-randomizing subjects into either a maintenance intervention-REGULAR group or a maintenance intervention-PLUS group will allow us to examine the "dose-response" of the maintenance methods if the intervention is effective.

结局指标
主要结局
Accelerometer (Omron Active Style Pro HJA-350IT) Measured Daily Steps
时间窗: Baseline, 3, and 9 months
This Omron Active Style Pro HJA-350IT comes with a Universal Serial Bus (USB) Connection and personal computer (PC) Software. The Active Style Pro HJA-350IT can display daily steps. The advantage of using the Omron Active Style Pro HJA-350IT is that the Omron Active Style Pro HJA-350IT will automatically reset the step count every evening at midnight while still allowing participants to view the past 7 days of step counts. Another advantage of using this Omron Active Style Pro HJA-350IT is that a researcher can select 1 of 4 Omron Active Style Pro HJA-350IT screen displays: (1) Steps display only, (2) metabolic equivalents (MET) display only, (3) 24-hour clock display (does not show any physical activity information), and (4) Steps, MET, and weekly average activities during the last four weeks. Data from the most recent 150 days performance will also be automatically stored so they can be directly downloaded to a computer.
