格里菲斯大学在《BMJ Public Health》发表的研究指出,澳大利亚若对含糖饮料征收20%的糖税,可在未来25年内预防370万例龋齿、19.1万例牙龈疾病和11.5万例完全失牙 1。研究指出,含糖饮料价格每上涨1%,消费预计下降1.2%,20%的糖税可使含糖饮料消费下降24% 1。研究建议将税收用于加强医疗和全民牙科服务,预计可产生约50万健康调整生命年 1。澳大利亚议会预算办公室估算,该税可在两个财年内筹集近14亿澳元 1。2024年,澳大利亚议会调查建议引入20%的含糖饮料税 1。
目前,口腔疾病占澳大利亚总健康负担的2.4%,近三分之一的15岁及以上澳大利亚人有未经治疗的龋齿,2017-2018年约9.1%的澳大利亚成年人每天饮用含糖饮料 1。英国在2018年引入糖税后,软饮含糖量减少了46% 1。澳大利亚医学协会主席Steve Robson表示100%支持该税 1。但澳大利亚饮料委员会反对糖税,称其将最严重打击低收入家庭 1。
A recent study published by Griffith University in BMJ Public Health highlights the significant public health benefits of implementing a 20% sugar tax on sugary drinks in Australia 1. Over the next 25 years, this policy could prevent 3.7 million cases of tooth decay, 191,000 cases of gum disease, and 115,000 cases of complete tooth loss, alongside a 24% reduction in sugary drink consumption 1. The research projects the generation of approximately 500,000 health-adjusted life years and recommends allocating the tax revenue to bolster healthcare and universal dental services 1. This scientific backing follows a 2024 Australian parliamentary inquiry that formally recommended introducing the 20% levy 1.
The Australian Parliamentary Budget Office estimates that the proposed tax would generate nearly 1.4 billion AUD over two financial years 1. The urgency for such a measure is underscored by current health data, which shows that oral diseases constitute 2.4% of the nation's total health burden, nearly a third of Australians aged 15 and older have untreated tooth decay, and roughly 9.1% of adults consumed sugary drinks daily in 2017-2018 1. Economic modeling suggests that every 1% price increase leads to a 1.2% drop in consumption, a dynamic mirrored in the UK, where a 2018 sugar tax resulted in a 46% decrease in soft drink sugar content 1. While Australian Medical Association President Steve Robson has voiced 100% support for the tax, the Australian Beverages Council opposes the policy, arguing it would most severely impact low-income households 1.
