Associations between frailty severity and dietary quality and food security among older Korean adults: a cross-sectional study.

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
backgroundFrailty in older adults is a multidimensional condition that extends beyond physical decline to include emotional and psychological vulnerability. However, evidence on how food security and overall diet quality vary according to frailty severity among older Korean adults is limited. This study aimed to systematically examine the associations between food security and diet quality, and frailty severity in this population.
methodsA cross-sectional study was conducted using data from the Korean National Health and Nutrition Examination Survey from 2013 to 2020. Among the 62,686 participants, 9,263 adults aged 65 years and older were included after those with missing frailty index variables, no nutritional records, or extreme energy intake values were excluded. Frailty was assessed using a 41-item Frailty Index (FI), categorizing participants into nonfrail (FI ≤ 0.15), prefrail (0.15 < FI ≤ 0.25), and frail (FI > 0.25) groups. Diet quality was evaluated using the Korean Healthy Eating Index (KHEI), and food security status was assessed through a standardized questionnaire.
resultsThe incidence of frailty was 14.1% in men and 23.8% in women, and it was associated with lower education, lower income, and living alone. KHEI scores decreased significantly with increasing frailty severity in both men and women (P for trend < 0.0001). Severe food insecurity was significantly associated with frailty risk with an OR = 3.62 (95% CI: 1.23-10.66) for men and an OR = 9.03 (95% CI: 2.92-27.97) for women. In the case of KHEI scores, only frail women had a significant trend for the odds of frailty (P for trend = 0.0202), whereas no significant association was observed in men.
conclusionsThese findings emphasize the importance of sex-specific nutritional interventions and stable food supply systems for preventing frailty in aging populations.
