Spatial disparity and factors associated with dementia mortality: A cross-sectional study in Zhejiang Province, China
Xiaotian Heng, Xiaoting Liu, Na Li, Jie Lin, Xiaoyan Zhou. Frontiers in Public Health, 2023-03-24
Topic: Risk, prevention and care in population studies
Thirty thousand three hundred and ninety-eight deaths attributable to dementia as the underlying or related cause (multiple causes) were reported during 2015-2019. Counties and districts in the southeast and west of Zhejiang province had significantly higher standardized mortality ratios than others. Counties and districts with a smaller proportion of residents aged 60 years or older, poorer economic status, insufficient health resources, and worse pollution had a higher risk of deaths due to dementia. Higher risks of dementia mortality were found in counties and districts with poorer economic status, insufficient health resources, and worse pollution in Zhejiang. Our study adds new evidence on the association between socioeconomic and environmental factors and the mortality risk due to dementia.
Key findings
- Thirty thousand three hundred and ninety-eight deaths attributable to dementia as the underlying or related cause (multiple causes) were reported during 2015-2019.
- Counties and districts in the southeast and west of Zhejiang province had significantly higher standardized mortality ratios than others.
- Counties and districts with a smaller proportion of residents aged 60 years or older, poorer economic status, insufficient health resources, and worse pollution had a higher risk of deaths due to dementia.
- Higher risks of dementia mortality were found in counties and districts with poorer economic status, insufficient health resources, and worse pollution in Zhejiang.
- Our study adds new evidence on the association between socioeconomic and environmental factors and the mortality risk due to dementia.
Why it matters
In Zhejiang Province, China, counties and districts with poorer economic status, insufficient health resources, and worse pollution had a higher risk of deaths due to dementia. The study is about socioeconomic and environmental factors associated with dementia mortality, not about treating, curing, or preventing Alzheimer's disease.

How this study scored 32/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 31 of the 96 points we could judge it on, which is 32 out of 100.
