Main finding

As reported in the abstract

Diet-attributable incident T2D, global
Incident T2D cases attributable to suboptimal diet
14.1 million (95% UI, 13.8-14.4 million)
Proportion of new T2D cases globally
70.3% (68.8-71.8%)

Further findings

Proportional burden by region · 2018

Central and eastern Europe and central Asia (highest)
85.6% (83.4-87.7%)
Latin America and the Caribbean (highest)
81.8% (80.1-83.4%)
South Asia (lowest)
55.4% (52.1-60.7%)

Diet-attributable T2D by sex, age, urbanicity and education · 2018

Proportions generally larger in men than in women and inversely correlated with age
Generally larger in urban vs rural and higher vs lower educated, except in high-income countries, central and eastern Europe and central Asia, where larger in rural and lower educated
