Polish Obesity and Sugar Consumption Trends Around the 2021 Sugar Tax

An ecological study analyzes population-level trends in Poland from 2014 to 2024. It uses nationally aggregated administrative and survey data on per-capita sugar purchases, sugar-sweetened beverage consumption, and healthcare use for obesity-related conditions. The research, authored by Michał Seweryn, evaluates associations with the introduction of a sugar tax in 2021.

Use Cases

• Modeling the impact of a sugar tax on per-capita sugar purchases based on time-series data from 2014-2024.
• Analyzing trends in sugar-sweetened beverage and sweets consumption using survey data from 2018, 2022, and 2025.
• Evaluating changes in healthcare utilization for obesity-related conditions, including bariatric surgery and pharmacological treatment.
• Assessing the association between policy implementation and population-level obesity rates using cross-sectional BMI data.

Strengths

• Data spans up to 11 years (2014-2024), providing a longitudinal view of trends.
• Integrates multiple national data sources, including the National Health Fund, Central Statistical Office, and National Public Health Institute.
• License is CC-BY-4.0, allowing for broad reuse and sharing.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The ecological study design means findings represent temporal associations rather than direct causal evidence.
