Actívatexto: Advancing Smoking Cessation and Physical Activity Among Latinos

The purpose of this randomized controlled trial is to assess the efficacy of Actívatexto (Aim 1) and the mediators of the presumed treatment effect (Aim 2) among Latino adults who smoke. Actívatexto is a mobile intervention that integrates four components: 1) a text messaging program that promotes both smoking cessation and physical activity, 2) wearable devices to monitor physical activity, 3) smoking cessation pharmacotherapy \[i.e., nicotine replacement therapies (NRT)\], and 4) an online dashboard where the research team manages participants' incoming and outgoing data from both the text messaging program and wearable devices.

We will conduct a two-arm randomized controlled trial among Latinos who smoke and do not meet the recommended levels of physical activity (N=408). Participants will be recruited via community-based efforts and randomly assigned in a 1:1 ratio to Actívatexto (a mobile intervention that promotes both smoking cessation and physical activity) or Decídetexto (a mobile intervention that solely promotes smoking cessation). All participants will be provided with nicotine replacement therapies and a Fitbit Versa 4 device. Participants in both groups will complete a baseline assessment at enrollment and follow-up assessments at Months 3 and 6.
