Health consequences of adolescent non-communicable disease risk factor reduction over 2020–2070

Income group	50-year cumulative health benefits (millions of premature deaths averted)
Income group	Tobacco use	Alcohol use	High body mass index	All risk factors
Low-income countries	1.5 (0.69 to 2.1)	0.46 (0.14 to 0.69)	0.10 (0.038 to 0.17)	2.0 (0.86 to 3.0)
Lower-middle-income countries	8.3 (2.2 to 14)	2.8 (1.0 to 3.9)	0.86 (0.33 to 1.4)	12 (3.5 to 19)
Upper-middle-income countries	4.3 (0.95 to 7.5)	0.72 (0.12 to 1.6)	0.53 (0.20 to 0.93)	5.6 (1.3 to 10)
High-income countries	0.82 (0.25 to 1.3)	0.24 (0.078 to 0.34)	0.075 (0.028 to 0.13)	1.1 (0.35 to 1.7)
Global	17 (4.6 to 28)	4.8 (1.6 to 7.4)	1.8 (0.67 to 3.0)	24 (6.8 to 39)

Estimates of premature (under-70) deaths averted, that is, statistical lives saved, are not discounted. Range of values given in parentheses come from the worst-case and best-case scenario analyses. ‘All risk factors’ totals may not add up exactly due to rounding. ‘Global’ totals aggregate the totals from the four income groups divided by 88% (the percentage of the 5–14 world population represented by the 70 countries).
