Overview

Background and Objectives: To compare the differences in musculoskeletal health with vitamin D alone in comparison with vitamin D with physical activity (PA) among chronic kidney disease (CKD) patients. Methods and Study Design: An open labeled, randomized, controlled trial was conducted at two tertiary care centers in Pakistan. Patients with CKD stage 2-4 and vitamin D deficiency (<20 ng/mL) were recruited in the trial. Both the arms were given oral vitamin D (cholecalciferol) drops (4000 IU) once daily for three months. One arm received only vitamin D (VD arm), while the second arm received vitamin D along with PA (VDPA arm). Results: Of the 1,235 CKD stage 2-4 subjects contacted, forty-six subjects were enrolled. Eighteen were assigned to VD arm and twenty-eight were assigned to VDPA arm. Between groups comparison shows that bicep strength increases from 15 to 17 kg. Likewise, back flexibility and aerobic fitness also increased among those who receive vitamin D and physical activity, however these differences were not statistically significant (p>0.05). Sensitivity analysis within group comparison shows rise of bicep strength from 13.8 kg to 15.2 kg in the VD alone arm (p=0.05); however, in the VDPA arm, there is a greater difference of 14.3 kg to 17.2 kg (p<0.001). Conclusions: Targeted PA among CKD patients has potential to improve bicep strength and back flexibility. However, as the sample size was small, further studies would be required to suggest whether a PA should be included as part of the treatment regimen.
