TOSS Feasibility + Fitbit Community = Reduced Obesity in Older Black Women

Study Overview
=================
Brief Summary
-----------------
The primary goal of this proposed physical activity (PA) intervention is to develop a realistic and an economical intervention to promote regular PA among older, overweight or obese Black women. Physical inactivity is prevalent among older Black women and this lifestyle behavior is both a destructive and expensive public health issue. Because many in this population do not engage in sufficient amounts of regular PA, this group miss the cardio-protective effects that may reduce many chronic conditions that disproportionately affect Blacks such as hypertension, diabetes, and obesity. The proposed obesity-reduction intervention is aligned with Stage 1 of the National Institute on Aging Stage Model for Behaviors Interventions Development. For the proposed hypothesis, the investigators propose a 2-group randomized controlled pilot, feasibility study in which 30 women will be randomized to receive either the TOSS PA Text messages Plus Fitbit community or the Control group and followed for 12 weeks to detect intervention effect.

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The researchers hypothesize that older overweight or obese Black women who participate in the PA intervention group (TOSS text messages plus Fitbit) will show increases in self-report and objective (assessed by accelerometer and a Fitbit) PA behaviors compared to the control group.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Physical Activity intervention group<br>Older overweight or obese Black women who participate in the physical activity intervention group will receive a daily text message from the TOSS study for 12 weeks, a Fitbit device plus have access to the Fitbit community option on their Fitbit app as an opportunity for virtual peer support. They will also receive an instruction pamphlet that describes the health benefits of regular physical activity (PA), safety instructions for PA, the national PA guidelines for older adults, suggested strategies to increase number of steps and an accelerometer pre and post-intervention. | Behavioral: TOSS Feasibility + Fitbit Community = Reduced Obesity in Older Black Women<br>* See arm description<br>|
| Active Comparator: Control group<br>The control will only receive a weekly neutral text message during the 12-week intervention. For this project, a neutral text message is defined as a message that only provides facts about a topic.They will also receive a Fitbit device, an instruction pamphlet that describes the health benefits of regular physical activity (PA), safety instructions for PA, the national PA guidelines for older adults, suggested strategies to increase number of steps and an accelerometer pre and post-intervention | Behavioral: TOSS Feasibility + Fitbit Community = Reduced Obesity in Older Black Women<br>* See arm description<br>|
