To model the potential effect of a proposed 10% tax on sugar-sweetened beverages on daily energy consumption and adult obesity prevalence across different demographic groups.
Applied an own-price elasticity estimate of -0.9 and a 90% tax pass-on rate to baseline consumption and obesity data from the 2007 Survey on Lifestyle and Attitude to Nutrition.
Employed a comparative risk assessment model to predict changes in daily caloric intake and obesity rates across age, sex, and income groups, complemented by sensitivity analyses.
A 10% tax was estimated to lower mean energy intake by 2.1 kcal/person/day, reducing the adult obese population (BMI ≥ 30 kg/m²) by 1.3%, or 9,900 individuals (95% credible interval [CrI]: 7,750 to 12,940).
Overweight and obesity prevalence combined (BMI ≥ 25 kg/m²) was predicted to decline by 0.7%, equating to 14,380 adults (95% CrI: 9,790 to 17,820).
Reductions were comparable across sexes (1.2% in men, 1.3% in women) and income levels (1.1% to 1.4%), but substantially greater in adults aged 18–24 years (2.9%) compared to adults aged 65 and older (0.6%).
