The prevalence of osteoporosis in postmenopausal women in urban Tianjin, China and its related factors

OBJECTIVES: The aims of the study are to understand the prevalence of osteoporosis in postmenopausal women in urban Tianjin, China and its related factors through a questionnaire and to assess the correlation between individual characteristics, physical mobility, psychological and emotional well-being, and prevalence, as well as people's awareness of osteoporosis. METHODS: We selected 240 postmenopausal women from 12 randomly selected streets in 6 administrative districts of Tianjin for bone mineral density measurement and a face-to-face questionnaire survey to obtain the relevant data. Female residents who had lived in the communities under the jurisdiction of the incorporated streets for more than 10 years and had been in menopause for 2 years were included. The women were made aware of the study, there were no communication barriers, and they were willing to undergo dual-energy absorptiometry and cooperate in completing the questionnaire. We used one-way analysis of variance, Fisher exact test, and Pearson correlation analysis for the statistical analysis. RESULTS: The overall prevalence of osteoporosis in postmenopausal women in the six districts of Tianjin was found to be 52.08%, and the χ 2 test for trend showed a clear trend of increasing with age ( P = 0.035). Body mass index was found to be the most significant personal characteristic affecting the prevalence of osteoporosis; the mean values of the nonosteoporosis and osteoporosis group were (25.45 ± 3.09) and (23.85 ± 3.16), respectively ( P < 0.001); previous fractures were closely associated with the prevalence of osteoporosis. Awareness about osteoporosis had not disseminated among the population, and 9.17% of the participants had never heard of the disease. While 75.42% and 72.92% of the participants, respectively, believe that the harm of osteoporosis cannot be compared with heart disease and cerebral infarction, 56.67% had never had an examination for osteoporosis and paid little to no attention to this disease. People still had major misconceptions about the hazards of osteoporosis and common-sense precautions that needed to be followed. CONCLUSIONS: Although osteoporosis is prevalent among postmenopausal women in urban Tianjin and is strongly linked to both history of fracture and body mass index, most women are only familiar with the disease's name and lack an understanding of the dangers it poses as well as the importance of early diagnosis and treatment. To ensure the prevention and control of osteoporosis, it is crucial to focus on increasing the examination and treatment rates and spreading awareness of the three-level diagnosis and treatment pattern among the public.
