63/100

✓ Peer-reviewed alzhub usefulness score 63 out of 100. Risk factors

Topic: Risk, prevention and care in population studies

Of 3037 participants, a weighted 57.8% (raw count, 1345) were younger than 75 years, 56.2% (raw count, 1777) were women, and most (84.9% [raw count, 2268]) were White. Over 7 years, 417 (weighted proportion, 12.1%) experienced food insecurity at least once. Food insecurity was associated with a faster decline in executive function in a fully adjusted model: the mean difference of annual change in executive function score between people exposed to and not exposed to food insecurity was -0.04 (95% CI, -0.09 to -0.003) points. However, food insecurity was not associated with changes in immediate and delayed memory (0.01 [95% CI, -0.05 to 0.08] and -0.01 [95% CI, -0.08 to 0.06], respectively). Conclusions and Relevance: Among community-dwelling older adults, food insecurity was prevalent and associated with a decline in executive function. Interventions and policies aiming to increase healthy food access or reduce food insecurity should be assessed for their impact on older adults' cognitive outcome.

Key findings

Of 3037 participants, a weighted 57.8% (raw count, 1345) were younger than 75 years, 56.2% (raw count, 1777) were women, and most (84.9% [raw count, 2268]) were White.
Over 7 years, 417 (weighted proportion, 12.1%) experienced food insecurity at least once.
Food insecurity was associated with a faster decline in executive function in a fully adjusted model: the mean difference of annual change in executive function score between people exposed to and not exposed to food insecurity was -0.04 (95% CI, -0.09 to -0.003) points.
However, food insecurity was not associated with changes in immediate and delayed memory (0.01 [95% CI, -0.05 to 0.08] and -0.01 [95% CI, -0.08 to 0.06], respectively).
Conclusions and Relevance: Among community-dwelling older adults, food insecurity was prevalent and associated with a decline in executive function.

Why it matters

This study found that food insecurity was linked to faster decline in executive function but was not linked to changes in immediate or delayed memory. It suggests reducing food insecurity might affect one aspect of cognition, but it does not test a treatment or cure for Alzheimer's disease.
