Impact evaluation of soft drink taxes as part of nutrition policies in Gulf Cooperation Council countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates

Background: Prevalence of overweight and obesity is high in the Eastern Mediterranean Region, and there are higher rates in Gulf Cooperation Council (GCC) countries. This had led GCC countries to impose policies that aim to decrease obesity, overweight, and diabetes rates. The objective of this research is to measure the impact of such implemented policy to reduce obesity, namely taxes applied to sugar-sweetened beverages (SSB) in GCC. Methods: : The impact of SSB taxes has been measured using a panel data set that covers sales volumes of soft drinks in GCC countries from 2010 to 2020. Results: : annual growth in soft drink sales volumes decreased; from 5.44% to 1.33% in Saudi Arabia, 7.37% to 5.93% in United Arab Emirates, and 5.25% to 5.09% in Bahrain from 2016 to 2017. In Qatar, a tax was implemented in 2019, and a reduction in sales volume growth was observed between 2019 and 2020 (3.78% to 2.45%), and in Oman a reduction was observed between 2018 and 2019 (3.60% to 2.99%). Kuwait was the last GCC country to implement taxes in 2020, and the growth in sales volumes decreased from 6.31% to 5.47% from 2019 to 2020. Conclusions: : The introduction of health-related taxes on soft drinks has been followed by a drop in the growth rates of sales in GCC countries. This, in turn, can be expected to contribute to a reduction in the prevalence of overweight and obesity, especially when combined with complementary public health policies and interventions. Hence, awareness campaigns should promote the reduction of the consumption sales of SSB and substitute with more consumption of fresh juices. These recommendations align with the recommended priority actions by the World Health Organization Strategy on nutrition for the Eastern Mediterranean Region 2020-2030 adopted by the countries of the Region in October 2019.
