简要总结
In this study, the investigators are exploring how a mindfulness-based physical activity program can help improve exercise habits and overall health among 258 inactive Latina women aged 18 to 65. The study will be conducted entirely remotely over and 18 month period. During the first 6 months, all participants will receive an exercise program that has previously been tested by our research team. After 6 months, the investigators will check if participants are meeting the recommended exercise guidelines of at least 150 minutes/week of at least moderate intensity activity. Participants who meet the guidelines will continue with the successful exercise program for another 6 months. For participants who do not meet the guidelines (are exercising less than 150 minutes/week), they will receive one of two enhanced programs, which will be randomly assigned. One program offers additional physical activity support, and the other incorporates stress management through mindfulness techniques. For all participants, over 18 months, the investigators will track physical activity levels, stress, and heart health indicators.
详细描述
The current study is an innovative adaptive intervention tested on inactive Latinas aged 18-65 (n=258). During the initial 6 month phase, all participants will receive our evidence based physical activity (PA) intervention. At 6 months, participants who meet national PA guidelines (at least 150 mins/week of at least moderate intensity PA) will continue to receive the standard PA intervention for another 6 months. Participants who do not meet the PA guidelines, will be randomized to continue intensive PA counseling or receive attention matched PA counseling incorporating the most potent components from Mindfulness-Based Stress Reduction (MBSR) adapted for PA. Participants in all 3 arms will be followed and compared over 18 months. The investigators will also rigorously evaluate stress as a mechanism for meeting PA guidelines using multiple measures (objective and self-report), including using wearable technology and Ecological Momentary Assessment (EMA). Finally, heart health indicators will be collected to assess long term benefits of PA.

结局指标
主要结局
Accelerometer-measured min/week MVPA
时间窗: 12 and 18 Months (outcome timepoints)
For the week prior to each assessment (baseline, 6, 12, 18-months), all participants will wear an Actigraph GT3X+ accelerometer, which measures movement and intensity of activity and has been validated against heart rate telemetry and total energy expenditure. Data will be used to generate a binary indicator of meeting national PA guidelines (at least 150 min/week MVPA) at each follow-up.
次要结局
- Perceived Stress Scale(PSS)(Baseline, 6 months, 12 months, 18 months)
- Moment to moment self-reported stress evaluated via Ecological momentary assessment (EMA)(Baseline, 6, 9, 12 months)
