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.
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.

| Remote Physical Activity Intervention | Behavioral | The intervention includes a Zoom goal setting session on PA at baseline and phone calls at week 1, and months 1, 2, 3, and 9 for new goal setting and to address questions and monitor progress on PA goals. Participants will receive mailings weekly in month 1, bi- weekly in months 2 and 3, and monthly in months 4 to 6, with maintenance doses in months 8 and 10. Mailings include motivation-matched physical activity manuals, tip sheets (on stretching, boredom, places to be active, etc.) and computer expert system-tailored PA feedback reports which draw from a bank of over 330 messages addressing psychosocial and environmental factors affecting PA. Participants receive one interactive text message on PA (goal setting and tips for increasing PA) daily for the first 6 months and weekly for months 7-12. |
| Measure | Description | Time Frame |
|---|---|---|
| Accelerometer-measured min/week MVPA | 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. | 12 and 18 Months (outcome timepoints) |
| Measure | Description | Time Frame |
|---|---|---|
| Perceived Stress Scale(PSS) | Measured using a 14-item Perceived Stress Scale(PSS), this self-report measure assesses general perceptions of demands in life exceeding one's capacities to manage them. This scale has shown good reliability and validity in past studies with Spanish speaking Latino participants. The scale score ranges from 0 to 56, with higher scores indicative of higher perceived stress. |
| Measure | Description | Time Frame |
|---|---|---|
| Lipid Panel | Heart health indicators will be collected at baseline and follow-ups (6, 12 and 18 months), including Total cholesterol, Triglycerides, HDL cholesterol and LDL cholesterol (all measured as mg/dl) | Baseline, 6 months, 12 months, 18 months |

All quantitative data produced in the course of the project will be preserved and shared upon reasonable request. Based on ethical considerations, only the following data produced in the course of the project will be preserved and shared: de-identified physical activity outcomes and questionnaire data.
Shared data generated from this project will be made available as soon as possible, and no later than the time of publication. The duration of preservation and sharing of the data will be a minimum of 7 years after the end of the funding period.
Researchers will need to contact the study PI (Dr. Marcus)

| Mindfulness Enhanced Remote Physical Activity Intervention | Behavioral | Women who do not meet the PA guidelines (60% based on our prior work), will be randomized to receive the Attention Matched Enhanced Remote PA intervention or Mindfulness enhanced remote Physical Activity intervention. The intervention includes a Zoom goal setting session on PA at baseline and phone calls at week 1, and months 1, 2, 3, and 9 for new goal setting and to address questions and monitor progress on PA goals. Participants will receive mailings weekly in month 1, bi- weekly in months 2 and 3, and monthly in months 4 to 6. In months 7-12, they will receive 4 monthly calls, 11 mailers and daily texts. In months 13-18, they will receive 1 call, weekly texts to self monitor daily PA and meeting goals. For the Mindfulness enhanced remote Physical Activity intervention participants will receive additional messaging and support to manage their stress through incorporating evidence based MBSR and mindful movement into their daily routine. |
