研究问题
Yet, informal caregivers continue to meet most care needs in Zambia and the number of healthcare providers with expertise in conditions that affect aging adults, particularly dementia, remains limited.；Dementia prevalence in Zambia is largely unknown and may range from 4.6%, as in nearby Tanzania, to as high as 27%, as shown in one rural hospital-based study,.；A few have compared dementia designation using the CSI-D cognitive or discrimination function score cutoffs with other dementia measures,, yet, it is not known whether the CSI-D participant interview in its current format reasonably summarizes the cognitive domains affected by dementia across populations.
方法
The Zambian Cohort of Healthy Aging and Dementia (Z-CHAD) study is an ongoing observational study of dementia and associated risk factors in a population-based sample of urban, peri-urban, and rural Zambians.；This analysis is drawn from participants recruited between August 7, 2023 and December 2, 2025 from four Lusaka communities - Chipata, Chawama, Chilenje, and Matero.；After enumeration, our teams returned to all households in the EA with eligible participants to discuss the study and obtained informed consent.；In each household, a participant and informant were recruited.
核心结论
Across the study communities, there were significant differences in demographic characteristics.；Specifically, Chilenje participants were more likely to be female (75% vs Chawama 73%, Chipata 61%, and Matero 63%, p < 0.01), older (68.1 yrs vs.；Chawama 66.3 yrs, Chipata 67.4 yrs, and Matero 65.4 yrs p < 0.01), and were less likely to be born outside of Lusaka compared to the other study communities (69% vs. ‖ 结论：These findings suggest that the development of more nuanced, culturally relevant dementia measures is necessary to address the growing burden of dementia in LMICs.
局限
Conversely, while model fit for language was satisfactory, item thresholds were less variable than in the memory domain (−1.99 to −0.71),, suggesting that the CSI-D might have limitations in what can be assessed about this cognitive domain in our setting.；The lack of difficulty in these items makes them useful for diagnosing advanced dementia and screening for delirium, though they are likely less helpful for assessing smaller longitudinal changes in cognition.；The CSI-D participant interview and its brief counterpart do have notable shortcomings, namely the lack of items assessing executive functioning.
