Abstract 2154: Actívatexto:Feasibility and acceptability of a mobile intervention that promotes smoking cessation and physical activity among Latinos

Abstract The purpose of this study was to assess the feasibility and acceptability of a mobile intervention that promotes smoking cessation and physical activity among Latinos. Twenty Latino adults who smoked and did not meet recommended levels of physical activity were recruited using community-based recruitment strategies. Participants received Actívatexto, a theory-based, culturally accommodated, 12-week text messaging intervention (available in English and Spanish) that promotes both smoking cessation and physical activity. Actívatexto integrates four components: 1) a text messaging program that promotes both smoking cessation and physical activity, 2) a wearable device to monitor physical activity, 3) an online dashboard where the research team manages participants’ incoming and outgoing data from both the text messaging program and wearable devices, and 4) smoking cessation pharmacotherapy (i.e., nicotine replacement therapies). We assessed self-reported 7-day point prevalence smoking abstinence (not smoking any cigarettes in the past seven days) at Month 3, weekly minutes of moderate to vigorous physical activity (MVPA), pharmacotherapy adherence, self-efficacy, and satisfaction. At baseline, participants’ mean age was 47.3 years old (SD 16.0), 55% of participants were female, 80% had completed high school or lower educational level, and 60% indicated that Spanish was their language of preference. Most participants (75%) smoked 1-10 cigarettes daily, 35% smoked their first cigarette within five minutes after waking up, and 60% used menthol cigarettes. At Month 3, 14 participants (70%) self-reported 7-day point prevalence smoking abstinence (90% follow-up rate). Fitbit-assessed mean minutes of MVPA per week increased from 113 (SD 127; range 0-399) at Week 1 to 177 (SD 163; range 0-513) at Month 3, although the difference was not statistically significant (p=0.15). Sixteen participants (88.9%, 16/18) reported NRT use in the past 90 days. Mean scores of self-efficacy for smoking cessation increased from 31.2 (SD 10.6) at baseline to 47.8 (SD 13.0) at Month 3 (p<0.01). Mean scores of self-efficacy for physical activity increased from 12.3 (SD 3.9) at baseline to 14.6 (SD 4.4) at Month 3 (p=0.2). Most participants reported being satisfied or extremely satisfied with the intervention (88.9%, 16/18). In conclusion, Actívatexto resulted in a noteworthy cessation rate at Month 3 (70%), increased mean minutes of MVPA per week, produced high use of NRT, increased self-efficacy for smoking cessation and physical activity, and was well received by participants. Additional testing in a formal randomized clinical trial is warranted to assess the efficacy of the intervention. Citation Format: Daimarelys Lara, Edgar I.
