Modelled health benefits of a sugar-sweetened beverage tax across different socioeconomic groups in Australia: A cost-effectiveness and equity analysis

This research assessed the potential cost-effectiveness, health gains, and financial impacts by socioeconomic position (SEP) of a 20% sugar-sweetened beverage (SSB) tax for Australia. The study demonstrated that from a 20% tax on SSBs, the most health-adjusted life years  gained and healthcare costs saved would accrue to the most disadvantaged in Australia. Whilst those in more disadvantaged areas would pay more SSB tax, the difference between areas is small. The equity of the tax could be further improved if the tax revenue were used to fund initiatives benefiting those with greater disadvantage.
