| Objective To study the relationship between nutritional metabolism (body mass index)and hip bone mineral jbdensity (BMD)in the elderly. Methods 430 elderly female patients with osteoporosis from January 2019 to June 2021 were collected. The age, height, weight, uric acid, creatinine, glomerular filtration rate (GFR), hip BMD, parathyroid hormone (PTH), N-terminal Osteocalcin (n-osrteoc), N-terminal procollagen I (PINP), 25 hydroxyvitamin D 3(25-OH-D3) were recorded. Pearson correlation test was used for the correlation test of each index. Results There were significant differences and negative correlation between BMD and GFR in different age groups. There was no significant difference in BMI, uric acid nitrogen, creatinine, uric acid, PTH, n-osrteoc and PINP in different age groups, but there was significant and positive correlation in 25-OH-D3. There was no significant difference in bone metabolism markers in different uric acid groups. There was significant and positive correlation in BMI, BMD, uric acid nitrogen and creatinine, and significant and negative correlation in GRF; There were significant differences in BMI, uric acid nitrogen, creatinine, uric acid and GRF in different BMD groups, and there was a positive correlation with BMI, uric acid nitrogen, creatinine and uric acid, and a negative correlation with GRF. There was no significant difference in bone metabolism markers in BMD groups. Conclusion Changes of BMI lead to the change of uric acid in vivo. Maintaining a certain BMI and uric acid has a positive effect on the maintenance of bone mineral density in elderly women. This effect is not related to the change of bone metabolism caused by hormone changes in vivo. |
