Screening results and influencing factors of osteoporosis in postmenopausal women in community

Objective To analyze the results and influencing factors of osteoporosis screening in postmenopausal women, and to evaluate the predictive power of OSTA scores on the risk of osteoporosis in postmenopausal women, so that to provide experience for peers to identify community-related osteoporosis. Methods A total of 5 191 postmenopausal women who participated in osteoporosis screening at Caolu Community Health Service Center in Pudong New Area, Shanghai were enrolled from March to April 2019. Osteoporosis screening was performed using a questionnaire combined with calcaneus bone mineral density by quantitative ultrasound system. Data analysis was performed using SPSS 24.0 software. Results Of the 5 191 postmenopausal women, 1 502 (28.93%) had intermediate and higher risk of osteoporosis, and the results of calcaneus ultrasound showed that the number of people whose T value ≤ -2 reached 1 280 (24.66%). The older the age, the smaller the BMI and the lower the OSTA score, the lower the T value (P<0.05). Whether the postmenopausal women were with low body weight, fragility fracture history, low back pain, history of falls, Parkinson's, uterus and ovarian cancer or not, and different osteoporosis risk rank, and the difference in T values measured by calcaneus ultrasound was statistically significant (P<0.05). Whether the OSTA score was ≤ -1, and whether the T value measured by the ultrasound of the calcaneus was ≤ -2, there was a poor consistency (Kappa=0.197<0.4, P<0.05). Conclusion The identification of community osteoporosis risk population could be evaluated by OSTA assessment, calcaneus ultrasound, in conjunction with other personal health history such as BMI or low body weight, fragility fracture history, low back pain, history of falls, Parkinson's, uterus and ovarian cancer.
