Brief Summary
This research aims to investigate the effectiveness of an automated Simple Message Service (SMS, also known as text messaging) advisor system relative to a proven human advisor program to promote regular, sustained physical activity among inactive, overweight Latinos. The SMS Advisor program represents a potentially lower-cost and high yield alternative to person-delivered health promotion programs that could be more rapidly disseminated with greater and faster uptake.

Outcome Measures
Primary Outcomes (1)
Change in weekly walking minutes from baseline to 12 months
Total weekly walking minutes measured by CHAMPS questionnaire (Stewart AL, Mills KM, King AC, Haskell WL, Gillis D, Ritter PL. CHAMPS physical activity questionnaire for older adults: outcomes for interventions. Med Sci Sports Exerc. 2001 Jul;33(7):1126-41)
baseline, 6 months, 12 months
Secondary Outcomes (2)
Body weight stability from baseline to 12 months
baseline, 6 months, 12 months
Change in moderate-to-vigorous physical activity from baseline to 12 months
baseline, 6 months, 12 months
Study Arms (3)
Telephone Support
EXPERIMENTALParticipants will receive bi-weekly 20 minute telephone calls from a trained professional facilitator offering physical activity advice with the goal of increasing moderate-to-vigorous intensity physical activity.
SMS Support
EXPERIMENTALParticipants will receive weekly text messages (3-5 text messages per week) offering physical activity advice with the aim of increasing moderate-to-vigorous intensity physical activity.
Attention-control
ACTIVE COMPARATORParticipants will receive telephone-based general nutrition advice.
Interventions
telephone-based physical activity advice and support delivered by a trained professional facilitator.
Telephone-based physical activity advice and support delivered by SMS.
