摘要

The correlation between the Nutritional Risk Index (NRI), a crucial metric for evaluating nutritional status, and depression as well as suicidal ideation has received little attention. This research aimed to find out the effect of NRI on suicidal ideation as well as depression. Data was gathered from the National Health and Nutrition Examination Survey (NHANES) 2005–2020. Weighted multiple logistic regression analysis were utilised to inspect the potential correlations between different NRI and suicidal ideation as well as depression. Furthermore, various subgroups were conducted to explored the differences in the correlations between NRI and depression as well as suicidal ideation. In all 13,424 participants were obtained. In a multiple logistic regression model with fully adjusted confounding variables, a lower risk of suicidal ideation [Odds Ratio (OR): 0.980, 95% confidence interval (CI): (0.965,0.995)] and depression [OR: 0.981, 95%CI: (0.972,0.991)] was linked to a higher NRI. A negative association between the NRI and the risk of depression was more significant in the elderly (≥ 60 years old) (OR (95%CI):1.294 (1.014, 1.651)), individuals with low education (OR (95%CI): 1.586 (1.342, 1.875)), males (OR (95%CI): 1.309 (1.091, 1.571)), and living alone (OR (95%CI): 1.369 (1.074, 1.744)). This study emphasized the negative correlation between NRI and depression and suicidal ideation, especially in certain populations. These findings emphasized that reducing the occurrence and development of depression and suicidal ideation should take NRI into account.
