• Registration Number: NCT04236882
• Lead Sponsor: M.D. Anderson Cancer Center

Brief Summary

This trial studies how well sleep and physical activity interventions work in increasing the physical activity of overweight or obese and sedentary African Americans. Sleep and physical activity interventions may help to increase physical activity among overweight and obese African American adults who do not get enough exercise.

Detailed Description

PRIMARY OBJECTIVES:

I. Determine the feasibility and satisfaction of a brief sleep intervention prior to or following a physical activity (PA) intervention and a contact control among overweight/obese sedentary African Americans.

II. Examine experiences of sleep among overweight/obese sedentary African Americans using qualitative focus groups/individual interviews.

SECONDARY OBJECTIVES:

I. Pilot test and evaluate the efficacy and sequential effects of a brief sleep intervention prior to or following a PA intervention in improving sleep, increasing physical activity, and reducing sedentary behavior, compared to a contact control group.

II. Explore the correlations among psychosocial (e.g., perceived stress, affect, neighborhood characteristics), biomarker (e.g., non-fasting glucose levels, blood pressure), and health behavior (e.g., diet and sedentary behavior) with sleep and PA.

OUTLINE:

FOCUS GROUPS AND INTERVIEWS: Participants attend either a focus group or interview about the sleep intervention and sleep-related problems over 90 minutes.

Participants are randomized to 1 of 3 groups.

GROUP I: Participants receive a web-based sleep intervention weekly during weeks 1-4. Participants then receive 2 web-based health coaching sessions over 30-45 minutes consisting of topics such as healthy shopping, increasing physical activity, identifying barriers, and eating out during weeks 5-9. Participants may optionally complete an interview over 1 hour at week 9.

GROUP II: Participants receive 2 web-based health coaching sessions over 30-45 minutes consisting of topics such as healthy shopping, increasing physical activity, identifying barriers, and eating out during weeks 1-4. Participants then receive a web-based sleep intervention weekly during weeks 5-9. Participants may optionally complete an interview over 1 hour at week 9.

GROUP III: Participants receive educational material on healthy homes. Participants also receive 2 web-based counseling sessions over 30-45 minutes consisting of topics such as indoor air quality, cardiopulmonary resuscitation (CPR) and first aid, and emergency preparedness at weeks 1 and 3. Participants may optionally complete an interview over 1 hour at week 9.
