Topic: Risk, prevention and care in population studies

The overall sample (N =329) was predominantly female (76.4%) with a mean age of 64.5 (range 45-92) and an average of 14.9 years of education (Table 1). Participants with a PACC≤1 SD (N =51) were more likely to be male, be older, be less educated, report less cohesion, and report being more depressed. SEM revealed that depression mediated the association between neighborhood cohesion and cognitive impairment. A one-point increase in neighborhood cohesion was associated with a -0.08 (SD=0.03, p <0.01) decrease in depression, and depression was associated with a 0.05 (SD=0.01, p <0.05)* increase in possible cognitive impairment (Figure 1). Discrimination was partially mediating the relationship between neighborhood cohesion and depression. A one-point increase in neighborhood cohesion was associated with -0.21 (SD=0.06, p <0.01) decrease in discrimination, and a one-point increase in discrimination was associated with 0.11 (SD=0.02, p <0.001) increase in depression. The area deprivation index was not associated with depression or cognitive impairment. Supportive mental health, social support, and positive interpersonal interactions with community members, regardless of neighborhood quality and socioeconomic disadvantages, are associated with better cognitive outcomes.

Key findings

The overall sample (N =329) was predominantly female (76.4%) with a mean age of 64.5 (range 45-92) and an average of 14.9 years of education (Table 1).
Participants with a PACC≤1 SD (N =51) were more likely to be male, be older, be less educated, report less cohesion, and report being more depressed.
SEM revealed that depression mediated the association between neighborhood cohesion and cognitive impairment.
A one-point increase in neighborhood cohesion was associated with a -0.08 (SD=0.03, p <0.01) decrease in depression, and depression was associated with a 0.05 (SD=0.01, p <0.05)* increase in possible cognitive impairment (Figure 1).
Discrimination was partially mediating the relationship between neighborhood cohesion and depression.

Why it matters

This study found that depression mediated the link between neighborhood cohesion and cognitive impairment in Black older adults. It does not test any treatment, cure, or prevention for Alzheimer's disease.
