Abstract
The relationship between sarcopenic obesity and hypovitaminosis D in individuals with chronic kidney disease is complex and has significant impacts on muscle and bone health. An observational, cross-sectional, and analytical study was conducted to analyze possible associations between serum vitamin D levels and sarcopenic obesity in patients with chronic kidney disease stages 3 and 4 in a cohort of patients under nephrology care. The presence of sarcopenic obesity was assessed using bioimpedance criteria, and vitamin D levels were measured and recorded for each patient. Statistically significant associations were found between sarcopenic obesity and suboptimal vitamin D levels (p < 0.005) as well as between severe sarcopenia and hypovitaminosis D (p < 0.05) in patients with chronic kidney disease stages 3 and 4. Patients with optimal levels of vitamin D showed better muscle quality and a lower prevalence of sarcopenia and severe sarcopenia. The findings suggest that vitamin D levels play a crucial role in muscle quality in patients with CKD stages 3 and 4. Maintaining optimal levels of vitamin D may help reduce the prevalence of sarcopenic obesity and improve quality of life in these patients.
