N2 - Physical inactivity is highly prevalent in Latinos. Use of smartphone technology may improve physical activity (PA) among Latino adults. We sought to determine the efficacy of a multi-component intervention to promote PA among Latino adults. We conducted a 3-month, 2-arm randomized trial among Latino adults with one or more risk factors for cardiovascular disease (CVD). We adapted a scripted, counseling approach into text messages and combined this intervention with brief motivational interviewing delivered by telephone. We compared this intervention to a control group. Both groups received a handout on the benefits of PA. During the baseline visit, participants completed a validated medical history survey as well as an assessment of quality of life and exercise behaviors. The primary outcome was change at three months in mean steps per week. We enrolled 69 patients, 35 in the intervention arm and 34 in the control arm. The mean age of the cohort was 58.7 years (SD 6.82). At baseline, mean steps per week were 65,218.2 (SD 25420.8) for intervention participants compared to 71,581.26 (SD 26118.07) for control participants, P = 0.36. At 3 months, the change in mean steps per week was 31,184.6 (SD 26121.52) for participants randomized to the intervention compared to 15,370.9 (SD 22247.84) for those randomized to control, P = 0.045. Among Latino adults with one or more risk factors for CVD, there was an increase in mean steps per week among those randomized to an intervention, involving the use of smartphones, versus control.
