Mindfulness-Based Interventions: Efficacy and Anxiety Data for Latin America

This statistical database, compiled by Juan Moises de la Serna in 2026, aggregates clinical study results and public health indicators regarding Mindfulness-Based Interventions (MBI) in Latin America. It synthesizes data from over 1,100 participants across Venezuela, Brazil, and Mexico, alongside regional anxiety prevalence statistics from PAHO/WHO 2021.

Use Cases

• Analyzing the correlation between MBI participation and cognitive performance metrics like attention (d=0.37) and working memory (d=0.35).
• Comparing regional anxiety prevalence (9.3% in Brazil vs 7.3% regional average) against global benchmarks.
• Evaluating the 73.9% treatment gap in relation to mental health access indicators and scientific publication trends from 2015-2024.

Strengths

• Includes specific effect sizes (d-values) for anxiety reduction (d=-1.26) and cognitive improvements.
• Aggregates data from regional-specific sources like SciELO and BVS alongside global databases.
• Provides specific sample sizes for clinical cohorts, such as n=818 for Brazilian nursing meta-analysis.

Limitations

• Small sample sizes for specific national clinical studies (e.g., n=153 for Venezuela).
• Secondary data compilation which may introduce selection bias from the literature review process.
• Geographic concentration on Brazil and Mexico may not represent the entire Latin American region.
