Conclusion

In a general population analysis with data from 1995 to 2012, risk factor changes accounted for 57% of the decrease in IS incidence. The most important contributors were the declines in mean SBP and prevalence of smoking, whereas the increasing DM prevalence contributed negatively to the IS incidence. These findings confer to the need to further reduce modifiable risk factors and encourage future research of less well-recognized risk factors.
