Across types of risk factors, behavioural risk factors accounted for 32·7% (30·7–34·8) of attributable DALYs, followed by metabolic risk factors at 16·8% (15·7–18·0), and environmental and occupational at 13·1% (12·1–14·2). This pattern was seen in middle SDI, middle-high SDI, and high SDI locations, while in low SDI and low-middle SDI locations environmental risk factors accounted for a larger proportion of attributable DALYs than metabolic risk factors. This is a pattern that has persisted since 1990; notably, however, the importance of metabolic risk factors is growing steadily in low SDI and low-middle SDI locations, while that of environmental and occupational risks has decreased during this time period. More detail can be found in appendix 2 (p 1399).
