Topic: Risk, prevention and care in population studies
Background Low socioeconomic status is associated with a higher risk for a number of health conditions, including cognitive impairment. Objective While the association with economic indicators has been well researched, aim of this paper was to investigate specifically the association between non-economic social deprivation and cognitive functioning later in life. Methods Participants without objective cognitive impairment at baseline (n = 91 controls, n = 106 with subjective cognitive decline) of the multicenter DZNE-Longitudinal Cognitive Impairment and Dementia Study (DELCODE) filled out a posthoc survey on social deprivation. Factor analysis identified four non-economic domains of social deprivation (Residential area conditions, Accessibility, Neighborhood support, Household distress). Cognition was assessed via the CERAD neuropsychological battery. Analyses were conducted using linear regression models as well as maximum-likelihood mixed-effects models adjusted for age, gender, years of education, marital status, depression, BMI, heart disease, hypercholesterolemia, hypertension, and diabetes. Results At the time of the survey, cognitive functioning was significantly lower among participants with high deprivation ( b = −0.21, p = 0.037). These participants also had a faster rate of cognitive decline ( b = −0.07, p = 0.006). Analyses of the deprivation sub-scores revealed statistically significant effects only for Accessibility ( b = −0.31, p = 0.001; rate of cognitive decline b = −0.07, p = 0.004). Conclusions Our findings suggest that non-economic social deprivation, especially in terms of access to a grocery store, pharmacy, postal office, and bus stop, might be relevant for maintaining cognitive functioning in old age. Further research should explore potential mechanisms of how these environmental conditions affect brain aging and neurodegenerative processes.
Key findings
- Background Low socioeconomic status is associated with a higher risk for a number of health conditions, including cognitive impairment.
- Results At the time of the survey, cognitive functioning was significantly lower among participants with high deprivation ( b = −0.21, p = 0.037).
- Analyses of the deprivation sub-scores revealed statistically significant effects only for Accessibility ( b = −0.31, p = 0.001; rate of cognitive decline b = −0.07, p = 0.004).
- Conclusions Our findings suggest that non-economic social deprivation, especially in terms of access to a grocery store, pharmacy, postal office, and bus stop, might be relevant for maintaining cognitive functioning in old age.
Why it matters
In the DELCODE study, people with higher non-economic social deprivation had lower cognitive functioning and faster cognitive decline, with significant effects only for the Accessibility domain. This links social conditions to cognition but does not test a treatment, cure, or prevention for Alzheimer's disease.

How this study scored 48/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 46 of the 96 points we could judge it on, which is 48 out of 100.
