A pilot study on the impact of body composition on bone and mineral metabolism in Parkinson's disease

The impact of body composition on bone and mineral metabolism in Parkinson's disease (PD) was evaluated. Body fat mass, lean mass, bone mineral content, and bone mineral density (BMD) were measured by DXA in 22 PD patients and 104 controls. Female patients exhibited reduced body mass index, fat mass, and BMD compared to controls (p<0.05). Significant positive correlation was found between 25 OHD levels and BMC. Diminished bone mass in women with PD was found to be associated with alterations in body composition and low 25 OHD levels.
