Potential causes of malnutrition in older adults in primary healthcare-A cross-sectional study.
Observational study in The journal of nutrition, health & aging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesTo evaluate the prevalence of the Determinants of Malnutrition in Aged Persons (DoMAP) and identify determinants of malnutrition among older adults attending primary healthcare. DESIGN AND
settingProspective, observational, monocentric study in primary healthcare.
participants500 older adults. MEASUREMENTS: Malnutrition was diagnosed using the Global Leadership Initiative on Malnutrition (GLIM) criteria. Potential causes of malnutrition were assessed by the attending physician using the DoMAP model with a 1:1 recruitment of malnourished and non-malnourished older persons.
resultsMalnourished individuals (mean age 81.7 ± 5.0 years; 59% women) exhibited a significantly higher prevalence of almost all DoMAP determinants compared to non-malnourished persons, particularly low intake (88 vs. 11%), high requirements (83 vs. 49%), poor appetite (73 vs. 9%), shopping difficulties (59 vs. 26%), inflammation (81 vs. 49%), gastrointestinal disease (17 vs. 2%), cancer (11 vs. 1%), depression (35 vs. 19%), dementia (21 vs. 6%), polypharmacy (60 vs. 38%), and hospitalization (27 vs. 4%). The mean total determinants count was significantly higher in malnourished participants (14.9 ± 5.0) than in non-malnourished ones (6.8 ± 4.4; p < 0.001). Regression analysis revealed low intake as the strongest determinant at Level1; poor appetite, forgetting to eat, shopping difficulties and inflammation at Level2; gastrointestinal disease, cancer and depression at Level3, and frailty and hospitalization at Level4.
conclusionThis study highlights the complex multifactorial nature of malnutrition in older adults attending primary healthcare, confirming the superior role of low intake and poor appetite among other determinants. The DoMAP model offers a structured framework for potential causative factors of malnutrition in older subjects.
