The prevalence of dementia in rural Tanzania: a cross‐sectional community‐based study

Abstract

The prevalence of dementia in this rural Tanzanian population is similar to that reported in high-income countries. Dementia is likely to become a significant health burden in this population as demographic transition continues. Further research on risk factors for dementia in sub-Saharan Africa is needed to inform policy makers and plan local health services.

The association between disability and cognitive impairment in an elderly Tanzanian population

“…People with dementia and MCI were over-sampled relative to the background population, where the prevalence of dementia is 6.4% [12]. Nevertheless, the data analysis techniques used are robust to these population characteristics, and no inferences have been drawn regarding the population as a whole.…”

“…Data for this study were collected as part of a wider dementia prevalence study, details of which have already been published [12]. Brief details of the study methodology are given below.…”

“…Using a random number generator, six villages, with a census population of 1277 people aged 70 years and over, were selected to form the basis of the study cohort. Exclusions, refusals and additions have been described previously [12]. The final study population was 1198 people during phase one screening.…”

Prevalence of Dementia and Its Associated Factors in Cotonou Teaching Hospital, Benin

“…Thus, Paraïso et al [6] recorded 2.6% in rural area (Djidja) and 3.7% in urban area (Cotonou) in a door-to-door research conducted in Benin in 2010 on dementia epidemiology with patients aged 65 and above, whilst Guerchet et al [12] recorded 6.7% in a cross-sectional research conducted in the year 2012 on dementia epidemiology within elderly population living in Brazzaville (Congo). Longdon et al [13] registered 6.4% prevalence in a cross-sectional community research on dementia prevalence in rural Tanzania. El Tallawy et al [14] also registered 2.3% in a research conducted in 2011 on dementia prevalence in Kharga (Egypte) in 2012, whilst Yusuf et al [15] estimated dementia prevalence at 2.8% in a community research on dementia prevalence and subtypes dementia within elderly population living in northern Nigeria.…”

Mild Cognitive Impairment in Rural Tanzania: Prevalence, Profile, and Outcomes at 4-Year Follow-up

“…Of the 52 villages in the Hai demographic surveillance site, 6 were selected using a random number generator, and our goal was to screen all those aged 70 and over in these villages. 14 Screening was carried out by trained census enumerators local to each village using the Cognitive Screening Instrument for Dementia (CSI-D). 15 This instrument has been validated in a number of LMICs and low literacy settings and has previously been translated and validated in Swahili in neighboring Kenya.…”
