Objective: To explore the trends and distribution of intracerebral hemorrhage (ICH) mortality of the residents with different characteristics from 1999 to 2015 in Tianjin. Methods: ICH mortality data in 1999-2015 were from Tianjin population based mortality surveillance system. The mortality rate of ICH, difference in the rate by gender, age, and geographic distribution, and trends over the years were analyzed. Standardized mortality rates of ICH were calculated using the year 2000 world standard population. Joinpoint regression and Cochran-Armitage trend were used to examine the trends in mortality. Results: A total of 102 279 ICH death cases were observed in Tianjin from year 1999 to 2015. The crude ICH mortality rate in Tianjin decreased from 76.35/100 000 in 1999 to 51.46/100 000 in 2015 (annual percent change (APC)=-1.96%, Z=-31.08, P<0.001) , and the standardized mortality rate decreased from 72.41/100 000 to 29.00/100 000 (APC=-5.20%, Z=-70.91, P<0.001). The crude mortality rate of ICH mortality in males decreased from 87.26/100 000 to 59.89/100 000 (APC=-1.79%, Z=-21.71, P<0.001) and the standardized mortality rate decreased from 85.65/100 000 to 35.75/100 000 (APC=-4.93%, Z=-52.32, P<0.001). The crude mortality rate of ICH mortality in females decreased from 65.21/100 000 to 42.98/100 000 (APC=-2.18%, Z=-22.28, P<0.001) and the standardized mortality rate decreased from 59.17/100 000 to 22.26/100 000 (APC=-5.63%, Z=-48.15, P<0.001). The ICH mortality rate under 35 years old increased from 0.78/100 000 to 0.92/100 000 (APC=4.41%, Z=5.07, P<0.001), especially in males increasing from 0.90/100 000 to 1.54/100 000 (APC=6.59%, Z=6.52, P<0.001). The crude mortality rate of ICH in urban areas decreased from 69.74/100 000 to 41.79/100 000 (APC=-3.18%, Z=-31.43, P<0.001) and the standardized mortality rate decreased from 57.56/100 000 to 20.42/100 000 (APC=-6.59%, Z=-53.43, P<0.001). The crude mortality rate of ICH in rural areas decreased from 82.99/100 000 to 61.49/100 000 (APC=-1.10%, Z=-14.06, P<0.001) and the standardized mortality rate decreased from 91.55/100 000 to 43.14/100 000 (APC=-3.78%, Z=-43.21, P<0.001). The ICH mortality rate in rural areas was higher than that in urban areas (P<0.05). Conclusion: ICH mortality rate in Tianjin decreased from 1999 to 2015. Further efforts to reduce ICH mortality in Tianjin is needed, in particular males, under 35 years old, and people in rural areas.
