Evidence informed priority setting: spotlight on introducing a Sugar-Sweetened Beverage (SSB) tax
iDSI collaborated with the University of Zambia’s School of Public Health to examine the potential impact of imposing a tax on SSBs over a period of 40 years for the Zambian population. Using a mathematical model developed by PRICELESS SA and local data, we showed that introducing a 25% tax on SSBs would reduce weekly per capita consumption of sugary drinks by between 102ml and 168ml – potentially extending life for a Zambian woman by 3.5 years; no significant benefit was observed for men.
Following the study, Zambia has joined the growing number of countries to have adopted a SSB tax to reduce the prevalence of lifestyle-related diseases such as obesity and type 2 diabetes.
