Vitamin D Status according to the Diseases in Hospitalized Rehabilitation Patients: Single Center Study

ABSTRACT

To investigate vitamin D status according to the diseases in patients admitted to the department of rehabilitation medicine. In total, 282 patients admitted to the department of rehabilitation medicine in our hospital were included. Patients were classified into 4 groups according to ailment stroke, traumatic brain injury, spinal cord injury, and fracture. All patients were also classified as ambulatory or non-ambulatory. Serum 25-hydroxyvitamin D (25[OH]D) levels were estimated at admission and at discharge. Bone mineral density (BMD) and ionized calcium levels were also measured. All subjects completed the Desmond Fall Risk Questionnaire for fall risk assessment. In total, 92 patients (59 males and 33 females; mean age, 69.09 ± 9.4 years) was enrolled. Low serum 25(OH)D levels (6–28 ng/mL) were observed in all patients in this study, and these were lower in the group of fractures resulting from falls than in the group of strokes (p < 0.05). Significant correlations were found between BMD and ionized calcium levels, Desmond Fall Risk Questionnaire scores and BMD, and questionnaire scores and serum 25(OH)D (p < 0.05). Serum 25(OH)D levels were lower in the department of rehabilitation medicine inpatients in our study than in the general population. The ambulatory patients had higher serum 25(OH)D levels at discharge than the non-ambulatory patients'. The hospitalized rehabilitation patients had lower serum 25(OH)D compared with the community. There were lower serum 25(OH)D levels in patients with fractures and non-ambulatory groups. We should pay attention to serum vitamin D levels of rehabilitation center inpatients.
