A Tailored Web and Text-based Intervention to Increase Physical Activity for Latino Men: Protocol for a Randomized Controlled Feasibility Trial
ABSTRACT
Background:
Latino men in the U.S. report low physical activity (PA) levels and related health conditions (e.g., diabetes, obesity). Engaging in regular PA can reduce the risk of chronic diseases and yield many health benefits; yet, there is a paucity of interventions developed exclusively for Latino men. To address the need for culturally relevant PA interventions, we developed Hombres Saludables, a 6-month Spanish-language, theory-based, tailored web and text message PA intervention for Latino men. This paper describes the study design, intervention, and evaluation methods for Hombres Saludables.
Objective:
The purpose of this paper is to describe the study design, intervention, and evaluation methods for Hombres Saludables, an internet- and text-based tailored Spanish-language PA intervention designed for an ethnically diverse population of Latino men.
Methods:
Latino men ages 18-65 were randomized to either the individually-tailored PA internet intervention arm or the nutrition and wellness internet control arm. The PA intervention includes: 2 check-in phone calls, automated SMS text messages, a pedometer, a 6-month gym membership, access to a private Facebook group, and an interactive website with PA tracking, goal setting, and individually-tailored PA content. The primary outcome is minutes/week of moderate-to-vigorous PA (MVPA) assessed via ActiGraph GT3X+ accelerometer and 7-Day Physical Activity Recall at baseline and 6-months. Secondary outcomes will examine potential moderators (e.g., demographics, acculturation, and environmental variables) and mediators (e.g., self-efficacy, cognitive and behavioral processes of change) of treatment effects at 6-months post-randomization.
Results:
Recruitment for the clinical trial occurred from February 2018 through July 2019. Baseline data collection occurred from February 2018 through October 2019 with a total of 43 participants randomized. Follow-up data was collected through April 2020. Data cleaning and analysis is continuing and is expected to be completed by November 2020 with final results expected to be published in 2021.
Conclusions:
Hombres Saludables uses an innovative, interactive web and text message-based intervention for improving PA among Latino men, an underserved population at risk of low PA and related chronic disease. If the intervention demonstrates feasibility, acceptability, and preliminary efficacy, we will refine and evaluate it in a larger randomized control trial. Clinical Trial: NCT03196570
