Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study the investigators are specifically targeting Latina women because they are more likely to be inactive and, therefore, are at higher risk for developing chronic conditions like obesity, diabetes, or cardiovascular disease. Through focus groups and cognitive interviews with Latinas in the Providence area, the investigators have modified our print-based intervention, already tested and proven to be effective in English-speaking communities, to be culturally and linguistically appropriate for the Latina community.

The objective of Seamos Saludables is to determine whether this culturally tailored print intervention will produce greater increases in physical activity levels among Latina women than a program focused on general health topics. Participants are randomly assigned to one of two groups (exercise and general wellness) and attend 4 clinic visits to complete baseline and follow-up assessments.

The investigators hypothesize that at the end of treatment, intervention participants will report significantly more minutes of at least moderate intensity physical activity per week than the wellness contact control participants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the U.S., Latinos report higher rates of inactivity and related health conditions (e.g., hypertension,hypercholesteremia, obesity, heart disease, stroke, diabetes) than non-Hispanic whites. Furthermore, Latino women (Latinas) report higher rates of sedentary behavior than Latino men. Due to cultural factors, socioeconomic circumstances, differences in educational background, and language barriers, Latinos in general, and especially Latinas, have limited access to public health interventions that promote physically active lifestyles. To address this public health crisis, effective interventions that leverage state-of-the-art theory and methods are needed. The investigators research group has 20 years experience developing and evaluating individually tailored computer expert system-driven physical activity interventions (based on Social Cognitive Theory and the Transtheoretical Model). In the investigators recent pilot study (R21NR009864), the investigators culturally and linguistically adapted the existing tailored intervention for sedentary Latinas and conducted a small randomized trial of the modified program (N=94). Six month (post-intervention) assessments are still ongoing, but three month data have been collected on 87 participants (93% retention). Intervention participants increased their physical activity from a mean of 17 minutes per week (SD=25.8) at baseline to 92 minutes (SD=69.8) at three months, whereas contact control participants reported increasing their physical activity from 12 minutes per week (SD=21.8) at baseline to 64 minutes (SD=84.3) at three months. The trends in the means at 3 months lend preliminary support for the efficacy of the intervention and the high retention rates, especially for a study targeting a hard-to-reach group like Latinas, bode well for its feasibility and acceptability. For the current proposal, the investigators will build on these encouraging results by conducting an adequately powered (N=312) randomized controlled trial to test the efficacy of the culturally and linguistically modified, individually tailored print intervention compared with a wellness contact control condition (e.g., cardiovascular health information from NHLBI in Spanish). Data will be collected at baseline, 6, and 12 months using well-established physical activity measures (7-Day PAR, Actigraphs), as well as a comprehensive set of psychosocial questionnaires. The investigators hypothesize that at the end of treatment, intervention participants will report significantly more minutes of at least moderate intensity physical activity per week than the wellness contact control participants. The investigators will also examine the maintenance of treatment effects at 12 months, costs of delivering the tailored intervention program, and potential mediators and moderators of the intervention-physical activity relationship. In the proposed study the investigators seek to promote physical activity among this at-risk population using a high-reach, low-cost strategy, which has great potential for adoption on a larger scale and thus high potential for reducing existing health disparities in the U.S.
