Using Social Networks to Promote Physical Activity in African American and Hispanic Women

The goal of this research study is to learn if enrolling in a program with a partner that involves monitoring each other's physical activity and providing support to one another can help both participants be more physically active.

Study Groups:

If you are found to be eligible to take part in this study, you and your partner will be randomly assigned (as in a flip of a coin) to be in 1 of 2 groups after you complete the first in-person visit. You will have an equal chance of being in any group.

If you are assigned to Group 1, the following tests and procedures will be performed:

* You will wear an activity tracker that you will be given at the baseline visit. The activity tracker is a small device worn on your wrist that records how many steps you have taken.
* You will be instructed in the use of a smartphone application at the baseline visit which you will use to track your physical activity, connect with your partner to share information about your physical activity, and provide support to your partner to be more physically active.
* You will have 6 counseling calls over the telephone throughout the study with a trained counselor and your partner.
* You will be emailed electronic newsletters to read that may help you be more physically active.

If you are assigned to Group 2, you will be sent the newsletters that may help you be more physically active and upon completing the16 week visit, you will be given an activity tracker and instruction in the use of a smartphone application.

Study Visits:

You will visit MD Anderson Cancer Center, Windsor Village United Methodist Church, or a community site 2 times (1 time at the beginning of the study, and 1 time 16 weeks after you begin the study). Each visit should take about 90 minutes. The following procedures will be performed:

* Your blood pressure will be measured. If you have a blood pressure reading higher than 140/90 mm Hg, you can participate in this study only with a clearance letter from your physician or nurse practitioner. If your blood pressure reading is higher than 180/120 mm Hg, the study staff must contact 911 and have EMS come and treat you due to your blood pressure being dangerously high. You have the right to refuse EMS services but study staff are still required to contact 911 immediately as a precaution. You will not be able to continue in the study until the clearance letter has been received.
* You will complete questionnaires about your feelings, moods, your motivation for physical activity, any social support you may receive from others, the neighborhood you live in, and other physical activity-related topics. The questionnaires should take about 45 minutes to complete. For the 2nd visit, you will have the option of completing the questionnaire online before your scheduled visit. This may reduce the length of your 2nd visit.
* You will be asked about your diet (for example, what you eat and drink each day).
* Your height, weight, and waist and hip circumference will be measured. To measure your waist and hip circumference, you may be asked to lift your shirt to expose your stomach area and lower your pants to expose your mid-hip area. The height, weight, and waist and hip circumference measurements should take about 10 minutes and will be performed in a private area.
* Your heart rate variability (HRV) will be measured with a wrist watch and a belt band. To measure your HRV, you will be asked to lift your shirt to expose your upper stomach area (at the breast bone). The band will be damp and should make firm contact with your skin. °You will wear the device for 5 minutes while it records your HRV as you sit quietly.
* You will be given an accelerometer at each visit. You will wear the accelerometer for 7 days and then return it in an pre-addressed envelope provided to you. An accelerometer is a small device that is worn on your hip that measures the amount of physical activity you do.

At 8 weeks after you begin the study, you will answer some questions either over the phone or through an online survey. The questions will cover the same topics as for the in-person visits. This should take about 30 minutes to complete.

All participants will be invited to take part in a final focus group. This focus group will take place sometime after the 16-week visit. You will be asked what you think about the study, including what you liked, did not like, and how you think it could be improved. If you want to provide this feedback but you cannot come to the focus group, you may provide feedback in another way (such as a phone interview or you could meet the study staff at the church or a community setting). These focus groups/interviews will be audio recorded. Your name and identifying information will be deleted from the recording before being transcribed (typed out) by an outside party. This should take about 90 minutes. The digital audio files will be destroyed within 10 years after publication.

Length of Study:

Your participation on this study will be over after you complete the final focus group visit.

Additional Information:

If you are assigned to Group 1, you may be contacted by phone or mail while you are taking part in this study to remind you about study visits, study procedures, and counseling calls.

You will be asked to give the names and contact information of family members and/or friends for the study staff to contact in the event they cannot reach you first.

The counseling calls for Group 1 will be recorded to monitor counseling procedures.

You will also be asked to participate in two optional procedures. First, you will be asked to "friend" your counselor on the mobile application so that the counselor can monitor your steps in preparation for the counseling calls. Second, you will also be asked to share your user ID and password for the activity tracker. This will enable research staff to download your physical activity data that will help staff to understand how much participants are using the device and how many steps they are taking. These data will only be examined during the 16-week study period, and you will be instructed to change your password at the end of the study.

If the accelerometer is lost or stolen, you will not be responsible for the replacement cost, but you should tell the study staff right away.

You will be able to keep the activity tracker after the study is complete.

Your home address may be used to access public information about the area where you live. This is to help researchers learn about how your neighborhood encourages physical activity. The results from this study will only be reported as a group and you will not be identifiable from any products resulting from this study (such as research papers). Your home address will never be released or published in any form. Your address will be stored separately from other study data, and only the study chair will be able to see the data after the neighborhood information has been collected.

You may be contacted in the future to see if you would agree to take part in other research studies.

Women who are pregnant or thinking about becoming pregnant during the study period will no longer be able to participate. If you become pregnant during this study, please tell the study staff right away.

This is an investigational study.
