| Objective To investigate the relationship between the cognitive situation of postmenopausal osteoporosis and bone mineral density in postmenopausal women. Methods A total of 1048 postmenopausal women were randomly selected in Fuzhou Han population. They were divided into cognition group (n =319 cases) and non-cognitive group (n = 669 cases)，and were investigated using a questionnaire. Bone mineral density (BMD) of the lumbar spine, femoral neck，large trochanter, and Ward s area was detected using dual energy X-ray, The correlation between cognitive group and bone mineral density in different parts was analyzed using a SPSS 20. 0 statistical software. Results (1) The bone mineral density of the lumbar spine in the cognitive group (0. 752 ± 0. 105 g/cm2) was significantly higher than that in the non-cognitive group (0. 734 ± 0. 098 g/cm2, P < 0. 01). The age， menarche, pregnancy, lactation number, culture degree, drink milk, sunlight，exercise time, and lumbar BMD were significantly different between cognitive group and non cognitive group (P < 0. 05). (2) The correlation between BMD and the influential factors was analyzed. BMD of the lumbar vertebrae was correlated with the cognition. Age, menarche, cognition, lactation number, and height were important factors for osteoporosis cognitive OP. (3) The prevalence of OP in the non-osteoporosis cognitive group and the cognitive group was 71. 16% and 70. 18% , respectively, with no statistical difference ( P >0.05). Conclusion The cognitive status of osteoporosis in postmenopausal women is associated with BMD. BMD of the lumbar vertebrae cognition group is higher than that in non-cognitive group, indicating that it is important to improve cognitive education for the prevention of osteoporosis. |
