Taxation of sugar-sweetened beverages in South Africa: Perspectives of consumers in Cape Town.

Background: Globally, fiscal measures are deemed effective in combating the obesity epidemic at population level. A health promotional levy (HPL) on sugar sweetened beverages (SSBs) was implemented in April 2018 in South Africa to reduce sugar consumption. Design and methods: This cross-sectional, descriptive study investigated consumers' understanding and opinion of the HPL, and impact on consumption of SSBs. Data was collected outside 15 grocery stores, within four health sub-districts of the City of Cape Town. An interviewer-administered questionnaire was completed with literate, adult consumers ( Results: Participants (46.0%) were aware of the HPL but regarded it insufficient to change purchasing behaviour (55.4%). The lower income group (56.4%) was most affected by the increased price of SSBs. Those who agreed (46.8%) that the levy would help to reduce the prevalence of obesity was significantly more likely to notice a price increase in SSBs (54.5%) ( Conclusions: Participants were receptive for legislative measures to combat the prevalence of obesity but lacked clarity of the goal and implementation of the HPL. A multipronged approach is crucial to lower sugar intake sustainably and an environment which offers healthy alternatives to SSBs. A higher HPL combined with transparency of how revenue is utilised could enhance the impact of the sugar tax strategy.
