Abstract

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 6-week program of motivational text messaging increases physical activity (step count) among older African Americans in an urban setting.

DESIGN:

RCT pilot study with assignment to motivational text messaging group or a control group.

SETTING/PARTICIPANTS:

Thirty-six African Americans aged 60-85 years.

INTERVENTION:

The intervention group received motivational text messages three times a day, 3 days a week, for 6 weeks. Both groups received pedometers and walking manuals to record step counts. The study was conducted and data were analyzed in 2011.

MAIN OUTCOME MEASURES:

The primary outcome measure was step count. The secondary outcome measure was perceived activity levels assessed by the Leisure Time Exercise Questionnaire (LTEQ).

RESULTS:

The group who received motivational text messages had greater improvements in step count (+679 vs +398; p<0.05) and perceived activity levels (p<0.05) than the group who did not receive text messages.

CONCLUSIONS:

Motivational text messaging three times a week for 6 weeks was effective in increasing step count and self-reported leisure time exercise behavior among older African Americans.

REGISTRATION:

This study is registered at www.clinicaltrials.govNCT01697475.
