rates for all three Level 1 risk factors, although the magnitude of decrease was larger for DALY rates than death rates. In the year 2016, behavioural risk factors accounted for the largest number of deaths (21·8 million [20·5 million to 23·3 million]) and DALYs (781·1 million [737·1 million to 830·1 million]). While there were decreases in both deaths and DALYs attributable to behavioural risk factors since 2006, these decreases were significant for deaths (2·5% [0·1–4·9]) and DALYs (14·3% [11·8–16·6]). There was a significant, 17·9% (15·7–20·6), increase in number of deaths attributable to metabolic risk factors, from 14·8 million deaths (14·0 million to 15·7 million) in 2006 to 17·5 million deaths (16·4 million to 18·5 million) in 2016, with similar increases observed for DALYs. Environmental and occupational risk factors accounted for the fewest number of deaths and DALYs, and there was a significant decline in both measures since 2006.Table 4Global all-age attributable deaths and DALYs, in 2006 and 2016, and percentage change of deaths, age-standardised death rates, DALYs, and age-standardised DALY rates between 2006 and 2016, for all risk-outcome pairs, both sexes combinedRisk2006 deaths (in thousands)2016 deaths (in thousands)Percentage change of deaths 2006–16Percentage change of age-standardised deaths rate 2006–162006 DALYs (in
