A systematic review of the prevalence and covariates of dementia or relative cognitive impairment in the older African‐Caribbean population in Britain

Abstract

The published research in this area is limited. The available studies consistently indicate an excess of dementia in older African-Caribbean people when compared to the indigenous white population. However, the magnitude of this difference and the associated risk factors are not clear, and warrant further investigation.

Presence of and correction for interviewer error on an instrument assessing cognitive function of older adults

“…The direction of the association of the respondent‐level variables with SPMSQ score was congruent with the existing literature . Higher scores for those predominantly interviewed in Malay or Tamil, relative to those predominantly interviewed in English, could be reflective of non‐equivalence of the SPMSQ across the various language versions.…”

“…Using multilevel statistical modeling, we “corrected” for interviewer error by subtracting the random intercept estimates obtained in model 2 for each interviewer from the respondent SPMSQ score. We consider this approach to be reasonable, as the model included respondent‐level variables most commonly associated with cognitive function . Thus, the residual interviewer‐level variance is likely as a result of interviewer‐level variables.…”

Prevalences of dementia and cognitive impairment among older people in sub-Saharan Africa: a systematic review

“…36 Studies of migrant African origin populations now living in Europe or North America have reported higher prevalences of cognitive impairment (range: 8-34%) but the majority of these studies included African-Caribbean participants or did not clearly distinguish the ethnic origins of study subjects. 37,38 Further research of firstgeneration sub-Saharan Africa migrant populations may provide more accurate data and insight into environmental factors associated with dementia.…”

Black, Asian and Minority Ethnic Communities and Dementia – Where Are We Now?

“…Lievesley [25] in updating his previous work on the UK black and minority ethnic ageing population [26] has pointed out that the 2011 Census shows that 58% of the black ethnic groups (Black AfricanCaribbean, Black African and Black other) live in London and also that the Black African-Caribbean population is demographically the 'oldest' of the Black ethnic groups. From the 2011 Census data this would mean over 2,700 of those who identified as Black AfricanCaribbean in the capital over 65 are likely to be living with dementia.…”
