| Objective To investigate the correlation between bone mineral density (BMD) and 25- hydroxyl-vitamin D (25OHD) in the elderly, in order to provide reliable clinical theoretical basis for the prevention and treatment of senile osteoporosis. Methods A total of 647 older than 60-year patients were selected in our hospital from 2013 March to 2014 October. BMD was measured using DXA. According to BMD, the patients were divided into osteoporosis group, low bone mass group, and normal BMD group. Age, height, body weight, and serum 25OHD content were compared among the groups. The correlation between BMD and above parameters was analyzed. Results The height, weight, and 25OHD content increased with the increase of BMD in the elderly patients, and the difference was statistically significant (P<0.0001). BMD was associated with body weight, height, and 25OHD, and the correlation coefficients were 0.303, 0.174, and 0.25, respectively. Multivariate linear regression analysis showed that body weight, height, and 25OHD were influential factors of BMD. Conclusion Height, weight, and 25OHD are influential factors of BMD in the elderly. Detection of serum 25OHD content can provide reliable clinical basis for prevention and treatment of osteoporosis in the elderly. |
