ADHD Prevalence and Incidence in Latin America and Globally (1990–2026)

Juan Moises de la Serna Tuya's dataset provides synthetic and coherent estimates for ADHD prevalence, incidence, and case numbers. It is based on Global Burden of Disease (GBD) 1990–2021 estimates for Latin American subregions and supplemented with country-level data from studies in Chile, Mexico, Brazil, and Colombia. The dataset includes interpolated and projected values for 1990–2026 and is intended for exploratory analysis, visualization, and educational purposes.

Use Cases

• Visualizing ADHD prevalence trends over time based on the 'year', 'region', and 'value' fields.
• Comparing ADHD measures (e.g., prevalence vs. incidence) across different 'age_group' and 'sex' categories.
• Assessing the burden of ADHD in specific Latin American countries using the 'country' and 'source' fields.
• Educational modeling of disease projections using the labeled 'Interpolated' and 'Projection' data points.

Strengths

• Covers a 37-year time range from 1990 to 2026, providing historical and projected data.
• Integrates data from an authoritative source (Global Burden of Disease) with peer-reviewed country studies.
• Contains 65,841 data points, offering a substantial volume for analysis.
• Includes clear annotation of synthetic data via 'indicator_type' and 'notes' fields.

Limitations

• Contains synthetic and projected values that are not official GBD figures, limiting its use for formal publication.
• The exact number of rows is not specified in the provided metadata.
• Country-level data mixes real study points with synthetic assumptions, requiring careful filtering.
