Disparities in neighborhood food environment and cognitive decline among US older adults: a cohort study

Table 2 Association between living in neighborhoods with low food access and low income and cognitive function among US urban community-dwelling older adults (N = 4768)

Model terms	Age adjusted B (95% CI)	P value	Fully adjusted B (95% CI)	P value
Low food access and low income	− 0.64 (− 1.69, 0.41)	0.23	0.58 (− 0.35, 1.50)	0.22
Study year	− 0.42 (− 0.47, − 0.36)	< 0.001	− 0.39 (− 0.46, − 0.33)	< 0.001
Low food access and low income × study year	− 0.18 (− 0.34, − 0.02)	0.03	− 0.19 (− 0.32, − 0.05)	0.01

Age adjusted model included age (year) at baseline. Fully adjusted models included baseline age (year), gender, race and ethnicity, educational attainment, log-transformed income, living arrangement, study year, census region, and street disorder, as well as interaction terms between study year with gender and race and ethnicity
The coefficient for low food access and low-income reflects the association between living in a low access and low-income neighborhood and baseline cognitive function
The coefficient for study year represents annual change in cognitive function
The interaction term between residing in a neighborhood with low food access and low-income and study year tests the study’s primary aim: the association between living in neighborhood with low access and low-income and cognitive change over time
