Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 2
Abstract
ObjectiveTo 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 2018ï¼ and to provide the basis for formulating relative intervention measures before and after senile dementia from an public-health view.MethodsBased on the collected data of death registrationï¼ focused on the senile dementia disease codes F03ï¼G30.0ï¼G30.1ï¼G30.8ï¼G30.9 according to The International Classification of Diseases 10th revision ï¼ICD-10ï¼. 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 ASRï¼ we calculated the standardized mortality rate of senile dementiaï¼ 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.ResultsThe crude mortality rate of senile dementia in the registered population in Shanghai from year 2002 to 2018 was 5.46/105ï¼ 3.50/105 in males and 7.43/105 in females. The standardized mortality rate of senile dementia was 2.61/105ï¼ 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 ï¼»APC=-5.5ï¼-6.5ï¼-4.5ï¼%ï¼P<0.01ï¼½. The trend of the standardized mortality rate of senile dementia decreased in both males ï¼»APC=-4.9ï¼-6.2ï¼-3.6ï¼%ï¼P<0.01ï¼½ and females ï¼»APC=-5.9ï¼-6.9ï¼-4.9ï¼%ï¼P<0.01ï¼½. The trend of the gender difference decreased ï¼»APC=-6.8ï¼-8.2ï¼-5.3ï¼%ï¼P<0.01ï¼½. The mortality rate of senile dementia was higher in females than in males ï¼»ï¼Ï2=33.63ï¼P<0.01ï¼ï¼½.ConclusionThe mortality rate of senile dementia in females is higher than in males in Shanghaiï¼ though the trend of the gender difference decreased. This gender difference is worth of attention.
