In a recent epidemiological study, health registry data estimated that 312,400 cases of cardiovascular disease (CVD) in a metropolitan population were directly attributable to preventable lifestyle and environmental risk factors.
The table below shows the proportion of these preventable CVD cases attributed to various risk factors.
| Risk Factor | Percentage of preventable cases (%) |
|---|---|
| Poor diet (high sodium/saturated fat) | 31.8 |
| Physical inactivity | 22.4 |
| Tobacco smoking | 18.3 |
| High alcohol consumption | 7.9 |
| Other combined risk factors | 19.6 |
