The potential impact on obesity of a 10% tax on sugar-sweetened beverages in Ireland, an effect assessment modelling study

Table 4 Estimated impact on obesity of a 10% tax by income (95% credible intervals)

Income group	Percentage reduction in obesity
Income group	Female	Male	Overall
Income group 1 (lowest)	1.4% (1.0% to 1.9%)	0.7% (0.5% to 1.0%)	1.1% (0.7% to 1.4%)
Income group 2	1.2% (0.8% to 1.6%)	1.0% (0.7% to 1.3%)	1.1% (0.7% to 1.4%)
Income group 3 (highest)	1.2% (0.8% to 1.6%)	1.5% (1.0% to 1.9%)	1.4% (0.9% to 1.8%)

Estimates are of the reduction in adults with a BMI ≥ 30 kg/m². Income groups are based on level of net household income and are grouped as follows: Group 1: <€19,999 per year; Group 2: €20,000-€39,999 per year; Group 3: >€40,000 per year. Estimates are based on a tax pass on rate of 90% and price elasticity of −0.9. Estimates are weighted for age and sex of the Irish population.
