Overview

Observational study characterizes sugar-sweetened beverage tax implementation globally, revealing key predictors of adoption.

Key Points

  • The study aims to characterize sugar-sweetened beverage tax implementation and identify national predictors of adoption.
  • Longitudinal analysis of global datasets from 1990 to 2024 across 183 countries.
  • Assessment of sugar-sweetened beverage tax characteristics and predictors like disease rates and GDP.
  • Used Cox proportional hazards models with time-varying covariates to analyze predictors of tax implementation.
  • 64 countries implemented sugar-sweetened beverage taxes from 1990 to 2024, covering 3.5 billion people.
  • South Asia led with 50% adoption; median tax rate was 7.5%.
  • Key predictors included diabetes prevalence (HR=1.22), obesity prevalence (HR=1.14), GDP per capita (HR per $10,000: 1.19), and SDI (HR=0.70).
