Mediation of nutritional status between the number of teeth and depressive symptoms in multi-ethnic older adults from Western China
Published 2025-04-01“…Mediation analysis confirmed nutritional status partially mediated the relationship between the number of teeth and depressive symptoms (indirect effect estimate = −0.059; 95% CI −0.076, −0.044, direct effect estimate = −0.089; 95% CI −0.158, −0.020). Furthermore, structural equation model for pathway analysis verified the correlation between the number of teeth, nutritional status, and depressive symptoms (p < 0.05).ConclusionNutritional status partially mediated the association between the number of teeth and depressive symptoms, revealing significant direct and indirect effects. …”
