Topic: Risk, prevention and care in population studies
Dementia mortality varied over 2-fold between DSPs (median rate ratio: 2.59). Significant variation in DSP slopes through time (variance 0.075, SE 0.020) indicated spatiotemporal variations. Mortality rates were significantly higher in the east (rate ratio 2.28; 95% confidence intervals, 1.45-3.60) compared with the north. There was a declining trend in 2 (east and northwest) of the 7 regions. Dementia mortality decreased by 15% in urban areas but increased by 24% in rural areas. Our findings indicate that regional inequalities in dementia mortality are salient, and the increase in mortality rates in rural areas is an emerging public health challenge in China. Tailored preventive health strategies should be in place to narrow down this avoidable and wholly unnecessary inequality.
Key findings
- Dementia mortality varied over 2-fold between DSPs (median rate ratio: 2.59).
- Significant variation in DSP slopes through time (variance 0.075, SE 0.020) indicated spatiotemporal variations.
- Mortality rates were significantly higher in the east (rate ratio 2.28; 95% confidence intervals, 1.45-3.60) compared with the north.
- There was a declining trend in 2 (east and northwest) of the 7 regions.
- Dementia mortality decreased by 15% in urban areas but increased by 24% in rural areas.
Why it matters
This study found that dementia mortality varied over 2-fold between disease surveillance points in China, with significantly higher rates in the east compared with the north. It found that dementia mortality decreased by 15% in urban areas but increased by 24% in rural areas, and suggests that tailored preventive health strategies should be in place to narrow this inequality.
