Introduction:
Meta Salud is a community health worker-facilitated intervention in Hermosillo, Sonora, Mexico, and was adapted from Pasos Adelante, a similar evidence-based intervention developed for a Latino population in the United States-Mexico border region. The objective of this study was to examine outcomes for Meta Salud and compare them with outcomes for Pasos Adelante.
Methods:
This pretest-posttest study took place during 13 weeks among low-income residents of an urban area. The program provided information on topics such as heart health, physical activity, nutrition, diabetes, healthy weight, community health, and emotional well-being; included individual and group activities aimed at motivating behavior change; and encouraged participants to engage in brisk physical activity.
Results:
We found significant decreases from baseline to conclusion in body mass index, waist circumference, hip circumference, weight, triglycerides, and low-density lipoprotein (LDL) cholesterol. From baseline to 3-month follow-up, we found significant decreases in body mass index, waist circumference, weight, LDL cholesterol, and glucose, and an increase in high-density lipoprotein cholesterol. Outcomes for Meta Salud were similar to those found for Pasos Adelante.
Conclusion:
The physiological improvements found among participants in Meta Salud and comparable changes among participants in Pasos Adelante suggest a scalable and effective behavioral intervention for regions of the United States and Mexico that share a common boundary or have similar cultural and linguistic characteristics.
