Redefining Dementia Disparities: A Closer Look at Race and Lifestyle
Dementia, a decline in cognitive function that affects daily life, has been observed to disproportionately affect racial minorities. This research delves into the disparities in dementia incidence, particularly focusing on racial and socio-economic factors. The UK Biobank study, which included over 323,000 respondents, found that racial minorities had a 24% higher risk of developing dementia compared to their white counterparts. Interestingly, this risk was somewhat reduced when socio-economic status (SES) was taken into account. The study also highlighted the significant role of lifestyle factors, termed as "Life's Essential 8 lifestyle sub-score (LE8LIFESTYLE)", which encompasses diet, smoking, physical activity, and sleep. These factors, when combined with SES, play a pivotal role in understanding the higher dementia risk among racial minorities. In essence, leading a healthier lifestyle and addressing socio-economic disparities could be key in reducing the prevalence of dementia across different racial groups.
