gut microbiota

This study utilized the National Health and Nutrition Examination Survey (NHANES) 2007-2018 data, with 13,857 participants included in the final analysis after excluding patients with incomplete data. Probiotic, prebiotic, synbiotic, and yogurt supplements intakes, OBS values, depression levels, sleep disturbances, and cognitive function were assessed based on questionnaires and laboratory data. Logistic regression, mediation effects analysis, and COX regression modeling were employed to explore these supplements’ associations with OBS values in relation to mortality linked to depression, sleep disorders, and cognitive dysfunction.
