Abstract:
Objective To investigate the characteristics of gender difference and the trend of the mortality rate of senile dementia in registered population in Shanghai from year 2002 to 2018， and to provide the basis for formulating relative intervention measures before and after senile dementia from an public-health view.
Methods Based on the collected data of death registration， focused on the senile dementia disease codes F03，G30.0，G30.1，G30.8，G30.9 according to The International Classification of Diseases 10th revision （ICD-10）. We analyzed the characteristics of gender difference in the mortality rate of senile dementia in registered population in Shanghai from year 2002 to 2018. According to ASR， we calculated the standardized mortality rate of senile dementia， and used the chi-square test to compare the difference between the gender mortality rates. The trend and the turning point of the mortality rate of senile dementia were determined by linear regression analysis by Join-point.
Results The crude mortality rate of senile dementia in the registered population in Shanghai from year 2002 to 2018 was 5.46/105， 3.50/105 in males and 7.43/105 in females. The standardized mortality rate of senile dementia was 2.61/105， 1.67/105 in males and 3.56/105 in females. The trend of the standardized mortality rate of senile dementia in 17 years decreased ［APC=-5.5（-6.5，-4.5）%，P<0.01］. The trend of the standardized mortality rate of senile dementia decreased in both males ［APC=-4.9（-6.2，-3.6）%，P<0.01］ and females ［APC=-5.9（-6.9，-4.9）%，P<0.01］. The trend of the gender difference decreased ［APC=-6.8（-8.2，-5.3）%，P<0.01］. The mortality rate of senile dementia was higher in females than in males ［（χ2=33.63，P<0.01）］.
Conclusion The mortality rate of senile dementia in females is higher than in males in Shanghai， though the trend of the gender difference decreased. This gender difference is worth of attention.
