The crude mortality rate, standardized mortality rate, death cause rank, and potential years of life lost rate (PYLLR) were calculated.

The mortality rate was higher in men than in women (χ²=142.156, P<0.001). The mortality rate in residents aged ＞45 years increased significantly, reaching a peak at age of 65 years.
