Comparison of dietary behaviors and nutrient intake by gender and household type among older Koreans: a cross-sectional study using data from the 8th Korea National Health and Nutrition Examination Survey.
Article in Korean journal of community nutrition, 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
objectivesThis study aimed to identify gender- and household type-specific nutritional vulnerability among older Koreans by comparing dietary behaviors, nutrient intake, and diet quality.
methodsWe analyzed data from 2,412 adults aged ≥ 65 years (1,118 men; 1,294 women) from the 8th Korea National Health and Nutrition Examination Survey (2019-2021). Household type was classified as one-person, couple-only, or with-children. Outcome variables included dietary behavior, daily energy and nutrient intake, and diet quality, assessed using the Korean Healthy Eating Index (KHEI). Analyses were carried out accounting for the complex sampling design, adjusting for age, residential area, education level, household income level, economic activity status, self-rated health status, and survey year.
resultsElderly men in one-person households, compared with those in couple-only households, were more likely to skip breakfast and lunch and to consume less energy. The odds of intake below the estimated average requirement (EAR) were higher for iron (odds ratio [OR] = 1.731, P = 0.022) and zinc (OR = 2.460, P = 0.002) among men in one-person households. The KHEI score was the lowest among men in one-person households. Elderly women in with-children households, compared with those in couple-only households, were more likely to skip breakfast and to consume less energy. The risks of intake below the estimated energy requirement (EER) and EAR were higher among women in with-children households than those in couple-only households (EER: OR = 1.448; magnesium: OR = 2.090; iron: OR = 1.692; zinc: OR = 1.902; folate: OR = 2.282; all P < 0.05). The KHEI score was lower among women in with-children households.
conclusionElderly men living alone and elderly women living with children showed significantly greater nutritional vulnerability. More attention should be given to understanding how gender-specific household types can affect nutritional vulnerability in later life.
