“…17 In Germany, 23.3% of postmenopausal German women aged 50 to 64 years had osteoporosis. 18 The prevalence of osteoporosis (25.7%) in this study was similar to the prevalence rate 19 Because of the silent nature of osteoporosis, most patients who do not undergo DXA are unaware of the diagnosis. Realisation usually comes when a fragility fracture occurs.…”

Objectives:To evaluate the prevalence of osteoporosis in treatment-naïve postmenopausal women, their treatment adherence, and the risk factors for osteoporosis.Design: Cross-sectional study of bone density reports, a self-administered health checklist, and computerised consultation records.Setting: Primary care sexual and reproductive health service in Hong Kong.Participants: Postmenopausal Chinese women who had never received osteoporosis treatment or hormone replacement therapy.Intervention: Each woman completed a checklist of risk factors for osteoporosis, menopause age, history of hormone replacement therapy, and osteoporosis treatment prior to undergoing bone mineral density measurement at the postero-anterior lumbar spine and left femur. The consultation records of those with osteoporosis were reviewed to determine their treatment adherence. Main outcome measures:T-score at the spine and hip, presence or absence of risk factors for osteoporosis, and treatment adherence.Results: Between January 2008 and December 2011, 1507 densitometries were performed for eligible women; 51.6% of whom were diagnosed with Bone health status of postmenopausal Chinese women IntroductionOsteoporosis is a major health problem in the elderly causing significant morbidity, mortality, and socioeconomic burden. Women are more vulnerable to osteoporosis than men because they have smaller and thinner bones. In addition, the sudden drop in ovarian oestrogen production around menopause New knowledge added by this study • Osteoporosis affects one in four postmenopausal Chinese women in Hong Kong.• Age, body mass index of <18.5 kg/m 2 , a positive parental history of osteoporosis or hip fracture, and duration of menopause are significant risk factors for osteoporosis.• Only 31% of osteoporotic women complied with the treatment protocol. Implications for clinical practice or policy • This study showed that osteoporosis is prevalent in Hong Kong Chinese postmenopausal women. Doctors should encourage postmenopausal women to have an adequate calcium intake, perform sufficient weightbearing exercise, and have enough sun exposure. Those with risk factors should also undergo dual-energy X-ray absorptiometry to ascertain their bone status.• Drug compliance is a problem in those with osteoporosis. Patient education should be provided to help them understand the importance of treatment compliance, the risk of fracture, and osteoporosis-associated morbidity and mortality.

“…The results of a systematic review of the studies in Tables 1 and 2 were reported based on the osteoporosis screening indices as well as the country in which the study was conducted. The lowest and highest sample sizes were related to the studies of Bakir et al (2018) ( n = 38) [ 30 ] and Lau et al (2015) ( n = 12,401) [ 31 ].…”

Background Osteoporosis is one of the most common bone system diseases that is associated with an increased risk of bone fractures and causes many complications for patients. With age, the prevalence of this disease increases so that it has become a serious problem among the elders. In this study, the prevalence of osteoporosis among elders around the world is examined to gain an understanding of its prevalence pattern. Methods In this systematic review and meta-analysis, articles that have focused on prevalence of osteoporosis in the world’s elders were searched with these key words, such as Prevalence, Osteoporosis, Elders, Older adult in the Science Direct, Embase, Scopus, PubMed, Web of Science (WoS) databases and Google Scholar search engine, and extracted without time limit until March 2020 and transferred to information management software (EndNote). Then, duplicate studies were eliminated and the remaining studies were evaluated in terms of screening, competence and qualitative evaluation based on inclusion and exclusion criteria. Data analysis was performed with Comprehensive Meta-Analysis software (Version 2) and Begg and Mazumdar test was used to check the publication bias and I2 test was used to check the heterogeneity. Results In a review of 40 studies (31 studies related to Asia, 5 studies related to Europe and 4 studies related to America) with a total sample size of 79,127 people, the prevalence of osteoporosis in the elders of the world; 21.7% (95% confidence interval: 18.8–25%) and the overall prevalence of osteoporosis in older men and women in the world, 35.3% (95% confidence interval: 27.9–43.4%), 12.5% (95% confidence interval: 9.3–16.7%) was reported. Also, the highest prevalence of osteoporosis in the elders was reported in Asia with; 24.3% (95% confidence interval: 20.9–28.1%). Conclusion The results of the present study showed that the prevalence of osteoporosis in the elders and especially elders' women is very high. Osteoporosis was once thought to be an inseparable part of elders’ lives. Nowadays, Osteoporosis can be prevented due to significant scientific advances in its causes, diagnosis, and treatment. Regarding the growing number of elderly people in the world, it is necessary for health policy-makers to think of measures to prevent and treat osteoporosis among the elders.

“…The prevalence of osteoporosis increased to 55.6% at the spine and 71.1% at the neck of femur in those aged 80 and above [ 11 ]. In another local study published in 2015, the prevalence of osteoporosis and osteopenia among 6099 women aged 50–89 years old was 24.9% and 51.7%, respectively [ 12 ]. In this study, the prevalence of osteoporosis and osteopenia was 23.7% and 60.4%, respectively.…”

Objectives To determine the prevalence of osteoporosis and the proportion who needed treatment after screening women aged 65 years or older; their treatment acceptance and continuation. Methods This is an observational study conducted between May 2017 and April 2020. Participants underwent clinical assessment and bone mineral density measurement of lumbar spine, total hip, and femoral neck by dual energy X-ray absorptiometry. Those with osteoporosis at any site or osteopenia with 10-year major fracture risk ≥ 20% or hip fracture risk ≥ 3% by Fracture Risk Assessment Tool® were offered drug treatment. Results Among 1800 participants, 15.9% were normal, 33.2% were low-risk osteopenic, 27.2% were high-risk osteopenic, and 23.7% were osteoporotic. Their mean age was 69.4 years and 6.3% had low-energy fractures after menopause. After stepwise logistic regression analysis, only prior low-energy fractures after menopause and low body mass index (BMI) remained significantly correlated with osteoporosis. Those who needed treatment were significantly older, menopaused at age 45 years or earlier, had a parent with hip fracture, had low-energy fractures after menopause, and low BMI. Drug was offered to 916 women but 67.6% refused because they worried about side effects, interaction with existing drugs, and were reluctant to take more drugs. Treatment acceptance was significantly higher among osteoporotic patients. Treatment continuation at 6th and 12th months was also significantly higher in osteoporotic patients. Conclusions Osteoporosis screening in elderly women identified a significant proportion who needed treatment. Encouraging them to initiate drug, especially high-risk osteopenic patients, remained a challenge.
