Associations Among Living Alone, Eating Alone, and Depressive Symptoms: Evidence from a Nationwide Study of South Korean Adults.
Article in Nutrients, 2026. 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
backgroundWith the continuous increase in the prevalence of single-person households, growing public health concerns have emerged regarding mental health. This study examined the associations among living alone, eating alone, and depressive symptoms.
methodsWe analyzed a nationally representative sample of 23,066 adults from South Korea. Participants were asked whether they lived alone or with other household members and whether they usually ate breakfast, lunch, or dinner alone. Depressive symptoms were assessed using the Patient Health Questionnaire-9. An analysis was conducted to estimate the direct and indirect associations among living alone, eating breakfast, lunch, or dinner alone, and depressive symptoms, using odds ratios (ORs) and 95% confidence intervals (CIs).
resultsAmong the participants, 12.7% lived alone and 87.3% lived with others. The prevalence of depressive symptoms was 10.6% among those living alone and 4.7% among those living with others. In the analysis, the OR (95% CI) for the total association between solitary eating and depressive symptoms was 1.94 (1.62, 2.35). The OR (95% CI) for the overall indirect association through eating alone was 1.36 (1.24-1.51).
conclusionsThis study found an indirect association between living alone and depressive symptoms through solitary eating. Future longitudinal studies are required to establish the temporal ordering among living alone, eating alone, and depressive symptoms and to validate our findings.
