A Pilot Study for Latinos and Non-Latinos to Evaluate Cultural Differences and Preferences for Weight Loss Using a Text Message Intervention

Americans have fallen into routines of higher caloric intake and sedentary lifestyles resulting in increased prevalence of obesity. Text messages (SMS) provide a novel solution for quick and accessible information and just-in-time prompts that can motivate change towards a healthier lifestyle. Our research goal was to pilot test an SMS-based weight loss program to determine if it accommodated cultural differences and was equally accessible to both English and Spanish speakers. A sample of 20 participants (non-Latino English n=5; Latino English n=5; Latino Spanish n=10) were divided into two language-based groups to test the intervention. For a period of eight weeks, participants received daily text messages and weekly phone calls. In addition, we provided them with a binder that included weekly-weight control themed information, and a pedometer to monitor their daily physical activity. At the 8-week post assessment, a semi-structured interview was conducted to collect participants’ feedback in relation to the overall program experience, effectiveness, and cultural appropriateness. Participants from both language groups identified pedometer use, text reminders, and the accountability component as key features for weight loss. On the other hand, cultural thematic differences created a barrier for Latinos who were trying to change their lifestyle. Results of this pilot study will be used to improve the intervention so that it addresses Latino’s social environment, work schedules, and culturally tailored foods. This pilot-study will give us useful data to launch a clinical trial of a 12-month weight loss program utilizing SMS health-based information at “one’s finger tips.”
