Food insecurity, food assistance, and physical and cognitive functioning among older Americans.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionFood insecurity is associated with adverse late-life health outcomes, including disability, dementia, and mortality. But its role in changes in physical and cognitive functioning remains unclear, as does the impact of food assistance.
methodsWe used weighted generalized estimating equations to investigate the association between food insecurity, food assistance, and physical and cognitive functioning among US adults aged 50 years and older (n = 6489). Using 2014 Health and Retirement Study (HRS) wave as the baseline, we extracted individual-level data from a HRS subsample from the 2013 Health Care and Nutrition Study and linked it to three additional HRS waves through 2020. This study included two outcome measures. First, physical functioning, a summary score of nine items that assessed difficulties in performing everyday physical activities (range 0-9), with higher scores indicating lower physical functioning. Second cognitive functioning, a composite score based on four cognitive tasks (range 0-27), with higher scores indicating better cognitive functioning.
resultsIn fully adjusted models, greater food insecurity was associated with lower physical functioning at baseline (β = 0.074 [95% CI 0.019, 0.129]) and showed marginal evidence of higher decline over time (0.010 [0.000, 0.020], p = .058). Food assistance was only associated with baseline physical functioning (-0·011 [-0·047, 0·025]). The triple interaction between food insecurity, food assistance, and time suggested that food assistance may attenuate declines in physical functioning (-0.014 [-0.030, 0.002], p = .078). Greater food insecurity (-0.206 [-0.305, -0.107]) and food assistance (-1.215 [-1.582, -0.848]) were associated with lower baseline cognitive functioning, but neither was associated with change over time. Food assistance did not moderate the association between food insecurity and changes in cognitive functioning over time.
conclusionsFood insecurity is associated with poorer physical and cognitive functioning in older adults. Strengthening policies and strategies that promote food assistance participation may help mitigate declines in physical functioning and improve health outcomes among older adults.
