Association between depressive symptoms and bone density in elderly patients with non-dialysis dependent chronic...

Area of Science:

• Nephrology
• Geriatrics
• Psychiatry

Background:

• Depression frequently co-occurs with chronic kidney disease (CKD) in elderly patients.
• The underlying causes and connections between these comorbid conditions are not well understood.
• Bone disorders are common in both CKD and depression, suggesting a potential link.

Purpose of the Study:

• To investigate the relationship between CKD-Mineral and Bone Disorder (CKD-MBD) markers and comorbid depression in elderly CKD patients.
• To evaluate the association between depressive symptoms and bone mineral density in this population.

Main Methods:

• A cross-sectional study involving 646 patients with CKD.
• Comparison of sociodemographic factors, kidney function, CKD-MBD markers, and bone mineral density based on depressive symptoms.
• Univariate and multivariate logistic regression analyses were performed.

Main Results:

• Patients with CKD and depressive symptoms had lower education, lived alone, exercised less, and had lower 24-hour urine phosphorus.
• Depressive symptoms were significantly associated with low bone density in the lowest body parts and total hip, even after adjusting for multiple confounding factors.
• Adjusted odds ratios for low bone density were 1.55 (95% CI: 1.06-2.29) and 1.72 (95% CI: 1.17-2.53) respectively.

Conclusions:

• Low bone density is linked to depressive symptoms in elderly patients with non-dialysis chronic kidney disease.
• Further research is needed to elucidate the complex interplay between CKD, depression, and bone health.
• Bone health assessment may be important in elderly CKD patients experiencing depressive symptoms.
