Impact assessment of the public health product tax in Hungary

Abstract Many countries apply fiscal policies to promote healthy diets to reduce the risk factors of NCDs. In 2011, a public health product tax (PHPT) was introduced in Hungary, taxing non-staple food products that carry proven health risks when consumed. The objectives of PHPT were to promote healthier eating habits by increasing the availability of healthy choices; to encourage reformulation; and to increase revenues for public health. With the purpose of evaluating the social and economic effects of PHPT, impact assessments (IAs) were conducted in 2012, 2014, and in 2018. The IA in 2018 was conducted within the framework of an EU-cofunded development project. To measure the awareness of the population on the law; to assess the population's attitude towards PHPT; to map the consumption patterns and to examine the major factors influencing food choices were fundamental parts of the IAs. We aim to present the findings of the latest IA and compare them to the results of the previous studies. Population surveys with questionnaires including the same questions were applied in the three assessments, hence changes during the 6 years could be detected. A sample of the adult population was involved in form of personal interviews in each IA. Based on the results, the awareness of PHPT was less (66%) in 2018 than in 2012 (72%). The adult population's consumption of the taxed products increased in all categories between 2012 and 2018 (except for salty condiments). Sociodemographic factors and awareness of the law correlated with the consumption of certain PHPT products. Taste was the primary determinant of food choice both in 2012 and 2018. The role of the price and the energy content in food choices were decreased significantly by 2018. A higher proportion of people identified the aims of PHPT correctly and agreed with them in 2018. The results draw attention to the importance of further interventions and the need of targeted health communication. Key messages The impact of the PHPT should continue to be monitored and evaluated. To achieve the aims of PHPT in the long term, it is needed to use more effective health communication, furthermore harmonized intersectoral actions should be also implied to promote healthy diet.
