41/100

✓ Peer-reviewed alzhub usefulness score 41 out of 100. Risk factors

Topic: Risk, prevention and care in population studies

Lower objective SES was associated with poorer performance on all cognitive domains: episodic memory (β = 0.115, p = 0.003), executive function (β = 0.210, p 0.05). When examining all SES indicators simultaneously, only the objective SES composite remained significantly associated with cognitive function. In secondary models, the objective SES composite score explained additional variance beyond education, income, and their standardized average. Objective SES showed the broadest and most robust associations with cognitive function relative to subjective and area-level indicators among cognitively normal older adults. Future studies may benefit from examining multiple financial indicators to better detect the extent and magnitude of cognitive deficits related to socioeconomic disadvantage in older adulthood.

Key findings

Lower objective SES was associated with poorer performance on all cognitive domains: episodic memory (β = 0.115, p = 0.003), executive function (β = 0.210, p 0.05).
When examining all SES indicators simultaneously, only the objective SES composite remained significantly associated with cognitive function.
In secondary models, the objective SES composite score explained additional variance beyond education, income, and their standardized average.
Objective SES showed the broadest and most robust associations with cognitive function relative to subjective and area-level indicators among cognitively normal older adults.
Future studies may benefit from examining multiple financial indicators to better detect the extent and magnitude of cognitive deficits related to socioeconomic disadvantage in older adulthood.

Why it matters

This study found that lower objective socioeconomic status was linked to worse performance across all cognitive domains in cognitively normal older adults. It does not test any treatment, cure, or prevention for Alzheimer's disease.
