Arms Assigned Interventions
Experimental: PA intervention and Maintenance plus
3-month physical activity intervention and 6-month maintenance intervention-Plus program
 Behavioral: Mobile phone based physical activity intervention with maintenance plus
This group will receive a mobile phone software program and a pedometer. Over a 3-month period, participants in this group will be asked to wear a pedometer, use a mobile phone physical activity diary, and respond daily physical activity messages or video clips. Over a 6-month maintenance period, participants will be asked to continue using a pedometer and a mobile phone physical activity diary.
Experimental: PA intervention and Maintenance regular
3-month physical activity intervention and 6-month maintenance - Regular program
 Behavioral: Mobile phone based physical activity intervention with maintenance regular
This group will receive a mobile phone software program and a pedometer. Over a 3-month period, participants in this group will be asked to wear a pedometer, use a mobile phone physical activity diary, and respond daily physical activity messages or video clips. Over a 6-month maintenance period, participants will be asked to continue using a pedometer.
Active Comparator: Pedometer
Non-intervention group
 Behavioral: Pedometer only
This group will receive a pedometer. Over a 9-month period, participants in this group will be asked to wear a pedometer.

Detailed Description:

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.
