Summary
Prevalence of Alzheimer's disease was significantly lower in older Cree adults in Northern Manitoba compared to Winnipeg residents. This study highlights potential ethnic variations in dementia prevalence.
Area of Science:
- Gerontology
- Epidemiology
- Neuroscience
Background:
- Dementia prevalence studies often lack diverse representation.
- Understanding ethnic variations in dementia is crucial for targeted public health initiatives.
Purpose of the Study:
- To compare the prevalence of Alzheimer's disease and all dementias between older Cree adults in Northern Manitoba and English-speaking Winnipeg residents.
Main Methods:
- Community survey and clinical assessment of 192 Cree aged 65+ in Northern Manitoba.
- Age-stratified sample of 241 English-speaking Winnipeg residents.
- Statistical analysis to compare prevalence rates and age-specific patterns.
Main Results:
- Alzheimer's disease prevalence was 0.5% in Cree vs. 3.5% in Winnipeg (p < .001).
- Overall dementia prevalence was 4.2% in both groups.
- Age-specific dementia patterns differed significantly between the two groups (p = .0254).
Conclusions:
- Significantly lower Alzheimer's disease prevalence observed in the Cree population.
- Dementia prevalence may vary across different ethnic and geographic groups.
- Further research is needed to explore factors contributing to these observed differences.
