Brief Summary:

This study examined the impact of using a motivational mobile text messaging intervention to increase step count among older community-dwelling African Americans. Secondary aims were to study the effects of text messaging on self-reported leisure time exercise behavior.


Participants in the motivational mobile text messaging group will have an increase step count after 6-weeks.

Condition or disease Intervention/treatment
Physical Activity Motor Activity Behavioral: Motivational text messaging

Detailed Description:

Background: Older minority populations can benefit from increased physical activity, especially walking. Text messaging interventions have the potential to encourage positive changes in health behavior in these groups.

Purpose: To examine if a six week program of motivational text messaging increases physical activity (step count) among older African Americans in an urban setting.

Design: Randomized, controlled trial pilot study with assignment to motivational text messaging group or a control group.

Setting/Participants: Thirty-six African Americans aged 60 to 85.

Intervention: The intervention group received motivational text messages three times a day, three days a week, for six weeks. Both groups received pedometers and walking manuals to record step counts. Study was conducted and analyzed in 2011.

Main Outcome Measures: Primary outcome measure was step count. Secondary outcome measure was perceived activity levels assessed by the Leisure Time Exercise Questionnaire (LTEQ).

Step count

Primary Outcome Measures :
  1. Primary outcome measure was step count [ Time Frame: 6-weeks ]
    Motivational text messaging led to greater improvements in step count (+679 vs. +398; P < .05)

Secondary Outcome Measures :
  1. Secondary outcome measure was perceived activity levels assessed by the Leisure Time Exercise Questionnaire (LTEQ). [ Time Frame: 6-weeks ]
    Motivational text messaging led to greater improvements perceived activity levels (P < .05) than the group who did not receive any text messages.
