Li Q, Yang Z, Zhu M, Li J, Lu C, Li Z, Kong C, Li H, Niu M, Kang P. Prevalence and risk factors of osteoporotic fracture among the elderly population in China: a multicenter cross-sectional study. INTERNATIONAL ORTHOPAEDICS 2024; 48:1323-1330. [PMID: 38467869 DOI: 10.1007/s00264-024-06145-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Accepted: 03/08/2024] [Indexed: 03/13/2024]
Abstract
PURPOSE Prevalence of osteoporotic fracture (OPF) is increasing with ageing, resulting in a significant financial burden for healthcare. However, research on the nationwide epidemiological data of OPF in Chinese elderly is still scarce. The aim of this study was to investigate the prevalence and risk factors of OPF in Chinese population aged 60 years or order. METHODS A cross-sectional survey was conducted in an elderly Chinese population in five centres. Questionnaire investigation and imaging examination were taken in all participants to identify OPF prevalence and risk factors. Diagnosis of OPF was determined based on imaging of vertebral fractures or history of fall-related fractures. We then used multivariate logistic regression model to analyze the associations between the potential risk factors and OPF. RESULTS The overall prevalence of OPF in population aged 60 years or older was 24.7% (1,071/4,331), showing an increasing trend with age (P < 0.001). The prevalence of OPF was geographically distinct (P < 0.001), but similar between men and women (P > 0.05). Up to 96.8% of OPFs consisted of vertebral fractures, especially involving T11, T12, and L1 segments. Advanced age (≥ 80), vision loss, severe hearing loss, multiple exercise forms, chronic kidney disease, osteoarthritis, and trauma-related vertebral fractures were significantly associated with risk factors, while education level and vitamin D supplementation were associated with protective factors of OPF. CONCLUSION High prevalence of OPF is a serious threat to bone health among elderly people in China. There is an urgent need for effective strategies to diagnose, prevent, and treat OPF in elderly adults.

Chang KC, Huang CT, Hsieh CT, Chen CM, Chang CJ. Risk factors for bone cement dislodgement following balloon kyphoplasty for osteoporotic vertebral compression fracture. Neurochirurgie 2024; 70:101559. [PMID: 38614310 DOI: 10.1016/j.neuchi.2024.101559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 04/01/2024] [Accepted: 04/02/2024] [Indexed: 04/15/2024]
Abstract
OBJECTIVE The study aimed to determine the incidence and risk factors associated with bone cement dislodgement in patients with osteoporotic vertebral compression fracture following balloon kyphoplasty treatment. METHODS A retrospective study was conducted on 203 patients who underwent kyphoplasty in 255 vertebral bodies between January 2017 and December 2021. The patients were categorized into two groups: the bone cement dislodgment group (n = 16) and the non-bone cement dislodgement group (n = 239). Various patient characteristics and radiologic parameters were evaluated. Statistical analysis involved the assessment of the background homogeneity of the group by using independent sample t tests, chi-square tests, and Fisher's exact. Univariate and multivariate logistic regression analyses were performed to explore the impact of background variables on cement dislodgement. RESULTS The results revealed that split-type fracture (χ2 = 31.706, p < 0.001), DISH (χ2 = 18.827, p = 0.011), pedicle fracture (χ2 = 22.246, p < 0.001), endplate deficit (χ2 = 14.023, p < 0.001), posterior wall injury (χ2 = 29.124, p < 0.001), and intervertebral vacuum cleft (χ2 = 21.469, p < 0.001) were the factors that significantly differed between the two groups. The multivariate logistic regression analysis revealed posterior wall injury (OR = 12.983, p = 0.025) and intervertebral vacuum cleft (OR = 5.062, p = 0.024) to be independent risk factors. CONCLUSION The incidence of bone cement dislodgement in our study was 6.3%. This study underscores the importance of using preoperative radiologic parameters to predict the risk of bone cement dislodgement following balloon kyphoplasty.

Effects of hospitalist co-management on rate of initiation of osteoporosis treatment in patients with vertebral compression fractures: Retrospective cohort study. J Orthop Sci 2023; 28:1359-1364. [PMID: 36244847 DOI: 10.1016/j.jos.2022.09.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 08/04/2022] [Accepted: 09/11/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND Vertebral compression fractures are common in elderly people and most are due to osteoporosis. Osteoporosis treatment is effective for secondary prophylaxis, so initiation is recommended. Despite the clear benefits, the rate of initiation of osteoporosis treatment is very low. It is reported to be due to several factors including insufficient systems-based approaches for hospitals and post-acute care. Hospitalists, who are physicians dedicated to the treatment of patients in hospital and whose activity is generalist rather than specialized, are reported to be associated with higher-quality inpatient care because of, among other things, closer adherence to guidelines. Co-management by hospitalists for patients with vertebral compression fractures has potential benefits towards improving the outcomes. We compared the rate of initiation of osteoporosis treatment for patients with vertebral compression fractures between conventional orthopedic surgeon-led care (conventional group) and hospitalist co-management care (co-management group). METHODS This is a single-center retrospective cohort study to evaluate the rate of initiation of osteoporosis treatment and reasons for non-initiation of osteoporosis treatment. Other clinical indicators were also evaluated, including length of hospital stay, preventable complications during hospitalization, and rate of 30-day readmission. RESULTS We identified 55 patients in the conventional group and 93 patients in the co-management group. The rate of initiation of osteoporosis treatment was higher in the co-management group (45.2% vs. 3.6%, OR 21.5; 95%CI 5.12-192.0; P < 0.01). Most of the patients with non-initiation in the co-management group had reasons for it described in the medical records, but in the conventional group the reasons were unknown. There was no significant difference in length of hospital stay, preventable complications during hospitalization, or 30-day readmission between the groups. CONCLUSIONS Hospitalist co-management of patients with vertebral compression fractures showed significantly higher rate of initiation of osteoporosis treatment than conventional orthopedic surgeon-led care.

Abstract
Osteoporosis is a condition characterized by decreased bone mineral density (BMD) and reduced bone strength, leading to an increased risk of fractures. Here, to identify novel risk variants for susceptibility to osteoporosis-related traits, an exome-wide association study is performed with 6,485 exonic single nucleotide polymorphisms (SNPs) in 2,666 women of two Korean study cohorts. The rs2781 SNP in UBAP2 gene is suggestively associated with osteoporosis and BMD with p-values of 6.1 × 10-7 (odds ratio = 1.72) and 1.1 × 10-7 in the case-control and quantitative analyzes, respectively. Knockdown of Ubap2 in mouse cells decreases osteoblastogenesis and increases osteoclastogenesis, and knockdown of ubap2 in zebrafish reveals abnormal bone formation. Ubap2 expression is associated with E-cadherin (Cdh1) and Fra1 (Fosl1) expression in the osteclastogenesis-induced monocytes. UBAP2 mRNA levels are significantly reduced in bone marrow, but increased in peripheral blood, from women with osteoporosis compared to controls. UBAP2 protein level is correlated with the blood plasma level of the representative osteoporosis biomarker osteocalcin. These results suggest that UBAP2 has a critical role in bone homeostasis through the regulation of bone remodeling.

Abstract
Osteoporosis is a major public health issue in Thailand, which increased morbidity, mortality, and health-care utilization. The objective of this review is to provide current perspectives on epidemiology, evaluation and management of osteoporosis in Thailand. According to epidemiologic data, the prevalence of osteoporosis and the incidence of hip fracture were comparable to the rest of the world. However, among Thai postmenopausal women, the prevalence of asymptomatic vertebral fracture was disproportionately high. In addition to established risk factors, conditions that may affect the risk of osteoporosis in the Thai population include certain genetic variants, thalassemia, vitamin D deficiency, and low dietary calcium intake, which requires further investigations to draw conclusions. In 2021, the Thai Osteoporosis Foundation released a new Clinical Practice Guideline that provides up-to-date evidence-based recommendations for evaluation and management of osteoporosis. Nonetheless, more research is required to provide local evidence in a variety of areas to guide management of osteoporosis in Thailand. These include epidemiology of distal radial fracture, the optimal intervention threshold of the Thai-specific Fracture Risk Assessment Tool model, screening for asymptomatic vertebral fracture, and the economic evaluation of osteoporosis management options, including fracture liaison service.

Prevalence of osteoporosis and incidence of related fractures in developed economies in the Asia Pacific region: a systematic review. Osteoporos Int 2023; 34:1037-1053. [PMID: 36735053 DOI: 10.1007/s00198-022-06657-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Accepted: 12/21/2022] [Indexed: 02/04/2023]
Abstract
UNLABELLED Robust data on osteoporosis in the Asia Pacific region could improve healthcare decision-making. Osteoporosis affects 10-30% of women aged 40 + , and up to 10% of men in 7 developed economies in Asia Pacific. Fractures affect 500-1000 adults aged 50 + per 100,000 person-years. Policymakers and clinicians must address this problem. PURPOSE Osteoporosis and associated fractures result in considerable morbidity, loss of productivity, early mortality, and increased healthcare expenses. Many countries in the Asia Pacific (AP) region, especially middle- and higher-income economies, are faced with aging and increasingly sedentary populations. It is critical to consolidate and analyze the available information on the prevalence and incidence of the disease in these countries. METHODS We systematically reviewed articles and gray literature for Australia, China, Hong Kong, Japan, Singapore, South Korea, and Taiwan. We searched PubMed, ScienceDirect, JSTOR, Cochrane, Google Scholar, and other databases for data published 2009-2018. We included articles with prevalence or incidence estimates for adults with osteoporosis or related fractures. RESULTS All locations had data available, but of widely varying quantity and quality. Most estimates for osteoporosis prevalence ranged from 10 to 30% for women ages 40 and older, and up to 10% for men. Osteoporotic fracture incidence typically ranged between 500 and 1000 per 100,000 person-years among adults aged 50 and older. Both outcomes typically increased with age and were more common among women. CONCLUSION Osteoporosis and associated fractures affect significant portions of the adult population in developed economies in the AP region. Governments and healthcare systems must consider how best to prevent and diagnose osteoporosis, and manage affected individuals, to reduce healthcare costs and mortality associated with fractures.

Abstract
In this population-based, cross-sectional study, we investigated vertebral fracture (VF) prevalence among Chinese postmenopausal women. We found 14.7% of population had VFs, which increased with age. Age ≥ 65 years, hip fracture, and densitometric osteoporosis were significantly associated with VFs. The prevalence of osteoporosis was remarkably high. PURPOSE To investigate VF prevalence among Chinese postmenopausal women in this population-based, randomized-sampling, cross-sectional study. METHODS The investigator obtained lists of women from communities. Randomization was performed using SAS programming based on age group in each region. Postmenopausal women aged ≥ 50 years in the urban community were included. The investigator interviewed subjects to collect self-reported data and measured BMD. Spine radiographs were adjudicated by Genant's semi-quantitative method. VFs were defined as fractures of at least one vertebra classified by Genant's score 1-3 and were analyzed using descriptive statistics. RESULTS A total of 31,205 women listed for randomized sampling from 10 Tier-3 hospitals at 5 regions. Of 2634 women in the full analysis set, 14.7% (388/2634, 95% CI: 13.4, 17.1) had prevalent VFs. VF prevalence increased with age (Cochran-Armitage test p < 0.0001) and was significantly higher in women aged ≥ 65. VF prevalence did not differ between North (14.4%, 95% CI: 12.5, 16.4) and South China (15.1%, 95% CI: 13.3, 17.1). In women with no prior VFs, prevalent VFs were 12.4% (95% CI: 11.2, 13.7). Age ≥ 65 years (OR: 2.57, 95% CI: 1.91, 3.48), hip fracture (OR: 2.28, 95% CI: 1.09, 4.76), and densitometric osteoporosis (OR: 2.52, 95% CI: 1.96, 3.22) were significantly associated with prevalent VFs. Prevalence of osteoporosis was 32.9% measured by BMD and 40.8% using NOF/IOF clinical diagnosis criteria. CONCLUSION VFs are prevalent among Chinese postmenopausal women who were ≥ 50 years and community-dwelled. Osteoporosis prevalence is remarkable when fragile fractures were part of clinical diagnosis.

The Difference of Disease Injury and Postoperative Recovery in the Occupational Characteristics of Thoracolumbar Fracture Patients: A Retrospective Study. Orthop Surg 2022; 14:2059-2072. [PMID: 35913219 PMCID: PMC9483088 DOI: 10.1111/os.13403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 06/20/2022] [Accepted: 06/23/2022] [Indexed: 02/05/2023] Open
Abstract
Objectives Understanding the occupational characteristics of patients is not only related to patients' life and health, but also conducive to improving their happiness. However, there were no studies that had been conducted on the relationship between occupation characteristic and postoperative recovery in patients with spinal fractures. The purpose of this study was to explore the relationship between the occupation characteristics of patients with thoracolumbar fracture and the characteristics of disease injury, treatment, and recovery so as to reduce the incidence and improve postoperative rehabilitation. Methods Patients (n = 719) with thoracolumbar fractures were recruited. Patients were grouped according to the characteristic of occupations: unemployed group (n = 299), white‐collar worker group (n = 20), and blue‐collar worker group (n = 400). Data were collected, including the characteristics, injury and treatment information, and the recovery records for 1 year after operation. One‐way ANOVA analysis, χ2 test, and binary logistic regression analysis was used to explore the relationship among these factors. Results Male, high‐falling injuries and single segment injury (mainly T 11, T 12 and L2) were common in patients with thoracolumbar fractures, especially in the blue‐collar worker group (70.8%, 78.3%, and 85.4%). Compared with the unemployed group, the patients in the white‐collar worker group and blue‐collar worker group had a higher proportion of young patients, a higher height and weight, a lesser rate of hypertension or diabetes. One week after injury, 73.4% of patients underwent surgery, with the blue‐collar worker group accounted for the largest proportion. One month after surgery, 77.1% of patients were able to get out of bed, with the white‐collar worker group accounted for the largest proportion. In the postoperative recovery information, patients in the blue‐collar worker group were more likely to have severe low back pain (OR = 2.023, 95% CI: 1.440‐2.284) and pain‐disturbed sleep (OR = 2.287, 95% CI: 1.585‐3.299) than those who in the unemployed group. Conclusions Blue‐collar workers, with a high risk of thoracolumbar fracture, have a higher incidence of low back leg pain and pain‐disturbed sleep in the recovery after thoracolumbar fracture surgery, and this requires more attention.

Abstract
IMPORTANCE The aging of the population is associated with an increasing burden of fractures worldwide. However, the epidemiological features of fractures in mainland China are not well known. OBJECTIVE To assess the prevalence of and factors associated with osteoporosis, clinical fractures, and vertebral fractures in an adult population 40 years or older in mainland China. DESIGN, SETTING. AND PARTICIPANTS This cross-sectional study, the China Osteoporosis Prevalence Study, was conducted from December 2017 to August 2018. A random sample of individuals aged 20 years or older who represented urban and rural areas of China were enrolled, with a 99% participation rate. MAIN OUTCOMES AND MEASURES Weighted prevalence of osteoporosis, clinical fracture, and vertebral fracture by age, sex, and urban vs rural residence as determined by x-ray absorptiometry, questionnaire, and radiography. RESULTS A total of 20 416 participants were included in this study; 20 164 (98.8%; 11 443 women [56.7%]; mean [SD] age, 53 [13] years) had a qualified x-ray absorptiometry image and completed the questionnaire, and 8423 of 8800 (95.7%) had a qualified spine radiograph. The prevalence of osteoporosis among those aged 40 years or older was 5.0% (95% CI, 4.2%-5.8%) among men and 20.6% (95% CI, 19.3%-22.0%) among women. The prevalence of vertebral fracture was 10.5% (95% CI, 9.0%-12.0%) among men and 9.7% (95% CI, 8.2%-11.1%) among women. The prevalence of clinical fracture in the past 5 years was 4.1% (95% CI, 3.3%-4.9%) among men and 4.2% (95% CI, 3.6%-4.7%) among women. Among men and women, 0.3% (95% CI, 0.0%-0.7%) and 1.4% (95% CI, 0.8%-2.0%), respectively, with osteoporosis diagnosed on the basis of bone mineral density or with fracture were receiving antiosteoporosis treatment to prevent fracture. CONCLUSIONS AND RELEVANCE In this cross-sectional study of an adult population in mainland China, the prevalence of osteoporosis and vertebral fracture were high and the prevalence of vertebral fracture and clinical fracture was similarly high in men and women. These findings suggest that current guidelines for screening and treatment of fractures among patients in China should focus equally on men and women and should emphasize the prevention of vertebral fractures.

Abstract
Objective This study aimed to determine the prevalence of vertebral fractures (VF) in a selected urban population in Malaysia and to explore possible variables associated with VF in the study population. Methods A cross-sectional study involving community-living, healthy subjects aged between 45–90 years from the state of Selangor, Malaysia, were invited to attend a bone health check-up. Subjects with diseases known to affect bone metabolism or were on treatment for osteoporosis (OP) were excluded. Bone mineral density (BMD) was measured using dual energy X-ray absorptiometry (DXA). Lateral and antero-posterior view lumbar spine x-rays were performed and VF was determined by the semi-quantitative Genant method. Results A total of 386 subjects were studied. Asymptomatic morphometric VF were found in 44 (11.4%) subjects. T12 was the most common vertebrae to be fractured. The prevalence of VF was significantly higher in menopausal women (12.4%) compared to non-menopausal women, in those above the age of 60 (18.5%), in those of Chinese ethnicity (16.5%), in those with a low body fat percentage (17.1%) and among those with OP (27.0%). The mean (standard deviation) 25-hydroxyvitamin D [25(OH)D] levels were significantly higher in those with VF compared to those without VF, 67.64 (23.50) and 57.47 (21.71) nmol/L, respectively. However, after multiple regression analysis, age over 60 years and OP on DXA BMD measurement were the only significant associated factors for VF. Conclusion Overall, 11.4% of a selected Malaysian urban population had asymptomatic morphometric VF. Age over 60 years and OP on DXA BMD measurement, but not 25(OH)D levels, were associated with VF.

Abstract
The increase in the incidence of hip fractures over time disappeared in Northern European and North American Caucasians after 2000, while an increase was observed in Asian countries including Japan until 2010. However, a decrease in the incidence was observed after 2010. The prevalence of vertebral fractures in Asians, Europeans, and American Caucasians is similar, and the incidences of clinical and morphometric vertebral fractures are higher in Asians compared with European Caucasians. The decrease in the incidence of vertebral fractures over time has been observed in Japan. Although the stabilization or decrease over time in the incidence of hip and vertebral fractures have been observed, the number of patients with these fractures is expected to increase rapidly with increases in the elderly population. Multidisciplinary measures to prevent fragility fractures are an urgent issue in Asia at this time. This narrative review outlines the recent trends in incidence and future burdens of hip fracture and vertebral fracture in Asia.

Abstract
OBJECTIVE To determine the prevalence of and risk factors for morphometric vertebral fracture (VF) in apparently healthy postmenopausal women with osteopenia. METHODS This cross-sectional study included 490 postmenopausal Thai women with osteopenia. All had no known history of low-trauma fracture, no underlying diseases, or history of taking medications that affect bone metabolism. Morphometric VFs were assessed by thoracolumbar spine x-rays, using the Genant semiquantitative method, and interpreted independently by three radiologists. RESULTS Mean age of participants was 59.9 ± 7.8 years and mean body mass index was 24.3 ± 3.4 kg/m2. Morphometric VFs were present in 29% (142/490) of women (grade 1: 62.0%, grade 2: 19.3%, and grade 3: 18.7%). Of these, 4.9% were aged 50 years or less, 40.1% were aged 50-59 years, 38% were aged 60-69 years, and 16.9% were aged over 70 years. Age and the Fracture Risk Assessment Tool (FRAX) scores for hip and major osteoporotic fracture, with or without bone mineral density, were positively correlated with VF. No differences in fracture prevalence among those with various degrees of osteopenia. Applying the current guidelines for VF screening results in discoveries of less than a half of osteopenic women who have had morphometric VF. CONCLUSIONS Almost one third of apparently healthy postmenopausal women with osteopenia had morphometric VF. Advancing age and greater FRAX scores were associated with higher prevalence of morphometric VF.

Abstract
Osteoporosis (OP) is a condition where there is low bone density and microarchitectural deterioration which can predispose to fragility fractures. There is a wealth of literature on OP from the developed countries, but less so from Asia. This review will explore the field of OP research in South-East Asia with regard to the epidemiology, the diagnosis of OP and the role of laboratory tests in the management of OP, with emphasis on 25-dihydroxyvitamin D and bone turnover markers.

BMC Musculoskelet Disord 2019; 20:435. [PMID: 31526375 PMCID: PMC6747745 DOI: 10.1186/s12891-019-2821-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2017] [Accepted: 09/10/2019] [Indexed: 11/13/2022] Open
Abstract
Introduction Vertebral fractures are common osteoporotic fractures, affecting 2–46% of the population, causing morbidity and increased risk of mortality. Physical activity has beneficial effects for bone health, including increased bone mineral density and reduced hip fractures. However, evidence concerning prevention of vertebral fractures is scarce. Therefore, the aim of this study was to investigate the association between leisure time physical activity and vertebral fracture risk. Methods The data were retrieved from the 2001 and 2007–2008 surveys of the Tromsø Study, a longitudinal population study in Norway. A total of 1904 participants (1030 women and 874 men, age 38–87 yr and 40–87 yr respectively) were included in the cross-sectional analysis (2007–2008). Prospective follow-up data (2001 to 2007) on physical activity were available for 1131 participants (636 women and 495 men, age 32–69 yr and 33–69 yr respectively). Physical activity was assessed by a questionnaire and vertebral fracture by lateral vertebral fracture assessment from dual-energy x-ray absorptiometry scans. Logistic regression was used to examine associations between physical activity and vertebral fracture. Results After controlling for confounders (age, height, weight, smoking, osteoporosis, osteoporosis medication, left hip total bone mineral density, and use of hormones in women only), no cross-sectional associations between physical activity levels and vertebral fracture were observed, OR 1.13 (95% CI: 0.59–2.13), for moderately active women and 1.44 (0.61–3.42) for highly active women, compared with sedentary women. In men, the respective ORs were 1.74 (95% CI: 0.91–3.35) and 1.64 (0.78–3.41). In the prospective analyses, OR for vertebral fracture in women with reduced physical activity was 0.81 (95% CI: 0.18–3.62), 1.24 (95% CI: 0.29–5.26) for increased physical activity and 1.54 (95% CI: 0.43–5.50) for active unchanged physical activity pattern, compared with sedentary unchanged physical activity. In men, the respective ORs were 2.05 (95% CI: 0.57–7.42), 2.23 (95% CI: 0.63–7.87), and 1.81 (95% CI: 0.54–6.02). Subanalyses of women and men ≥50 yr showed similar results. Conclusions Our findings suggest that physical activity does not play a major role in preventing vertebral fractures in Norwegian adults. Future studies may benefit from data on incident vertebral fracture, and objectively measured physical activity.

Abstract
Vertebral fracture (VF) is a common osteoporotic fracture, while its epidemiology varies according to regions and ethnicities, little is known about it in Japan. Using whole-spine radiographs from a population-based cohort study, the Research on Osteoarthritis/Osteoporosis Against Disability study 3rd survey performed in 2012-2013, we estimated the sex- and age-specific prevalence of VF in the Japanese. Genant's semiquantitative method (SQ) was used to define VF; SQ ≥ 1 as VF, SQ = 1 as mild VF, SQ≥ 2 as severe VF. We also revealed accurate site-specific prevalence, and associated factors with mild and severe VF. The participants were 506 men [mean age 66.3 years, standard deviation (SD):13.0] and 1038 women (mean age 65.3 years, SD: 12.6). The prevalence of VF in participants aged under 40, in their 40s, 50s, 60s, 70s, and ≥ 80 years was 17.4, 7.9, 18.5, 25.6, 26.3, and 41.5%, respectively, in men, and 2.9%, 2.4%, 7,3, 10.3, 27.1, and 53.0%, respectively, in women. Men had a significantly higher prevalence of mild VF (21.2%) than women (10.0%, p < 0.001); whereas, severe VF was significantly more prevalent in women (9.1%) than in men (4.7%, p = 0.003). VF was distributed with 2 peaks regarding site; one large peak at the thoracolumbar region, and another at the middle thoracic lesion. Low back pain and decreased walking ability were independently associated with severe VF, but not with mild VF, after adjustment for participant characteristics. Decreased walking ability was associated with multiple VFs in women, but not in men.

The epidemiology of osteoporosis, associated fragility fractures, and management gap in China. Arch Osteoporos 2019; 14:32. [PMID: 30848398 DOI: 10.1007/s11657-018-0549-y] [Citation(s) in RCA: 120] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Accepted: 11/12/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND Osteoporosis has been one of the most common but largely under-diagnosed clinical problems among elderly population. The disease burden is even greater in China because of limited medical resources and large population size. This article is aimed to provide an overview of disease burden, secular trend, and management gap of osteoporosis and related fractures in China. METHODS Based on the related studies published in English and Chinese from 1990 to 2017, we investigated the prevalence/incidence of osteoporosis and osteoporotic fracture in Chinese mainland, Hong Kong, and Taiwan, characterizing the secular trend and disease burden in different regions. Strict inclusion criteria were applied to control the study quality. We further examined the diagnosis and treatment gap of osteoporosis management observed in clinical practice in China and summarized the efforts made by Chinese government and scholars to combat this situation. RESULTS Twenty-seven studies concerning osteoporosis prevalence in China (including Chinese mainland, Hong Kong, and Taiwan) met the inclusion criteria and were included in the final analysis. Another 15 studies about hip fracture incidence and 13 studies about vertebral fracture prevalence/incidence were also included. The epidemiological data varied greatly across studies due to different design and population included. A higher prevalence was indicated in female population, older age groups, and residents in northern China compared to their counterparts. Though attenuated increased rates or slight decline patterns have been observed in Hong Kong and Taiwan, osteoporotic fracture incidence still showed steady increase in Chinese mainland. The diagnosis and treatment of osteoporosis as well as post-fracture management were still insufficient in China. CONCLUSION Due to its silent nature, osteoporosis and its related fractures remain largely under-diagnosed and under-managed in China. It also highlights the scarcity of high-quality studies specifically focus on longtime documentation of disease burden change and male population, especially in mainland area.

Abstract
Minodronate is a third-generation bisphosphonate that was developed and approved for clinical use in osteoporosis therapy in Japan. The mechanism of action for suppressing bone resorption is the inhibition of farnesyl pyrophosphate synthase, a key enzyme in the mevalonic acid metabolic pathway of osteoclasts, to induce apoptosis of the cells. Minodronate is the strongest inhibitor of bone resorption among the currently available oral bisphosphonates. Large randomized, placebo-controlled, double-blind clinical trials have revealed an increase in bone mineral density of both the lumbar spine and femoral neck over 3 years of daily minodronate therapy and risk reduction in vertebral fractures over 2 years of therapy. The increase in bone mass and the prevention of vertebral fractures are similar to those with alendronate or risedronate. The incidence of adverse events, especially gastrointestinal disturbance, is the same as or less than that with weekly or daily alendronate or risedronate. The unique mechanism of action of minodronate via the inhibition of the P2X(2/3) receptor compared with other bisphosphonates may be an advantage in reducing low back pain in patients with osteoporosis. The monthly regimen of minodronate, introduced in 2011, is expected to have better patient adherence and longer persistence. In experimental animal models, minodronate preserved, or even ameliorated, bone microarchitectures, including microcracks and perforation of the trabeculae in the short term. The lowest incidence of bisphosphonate-related osteonecrosis of the jaw among all bisphosphonates and the lack of atypical femoral fractures attributed to its use to date, however, are partly because only a smaller population used minodronate than those using other bisphosphonates. To date, minodronate is available only in Japan. Hip fracture risk reduction has not been verified yet. More clinical studies on minodronate and its use in osteoporosis treatment, with a large number of subjects, should be conducted to verify hip fracture risk reduction and long-term results.

Abstract
We investigated the prevalence and incidence of vertebral fractures worldwide. We used a systematic Medline search current to 2015 and updated as per authors' libraries. A total of 62 articles of fair to good quality and comparable methods for vertebral fracture identification were considered. The prevalence of morphometric vertebral fractures in European women is highest in Scandinavia (26%) and lowest in Eastern Europe (18%). Prevalence rates in North America (NA) for White women ≥50 are 20-24%, with a White/Black ratio of 1.6. Rates in women ≥50 years in Latin America are overall lower than Europe and NA (11-19%). In Asia, rates in women above ≥65 are highest in Japan (24%), lowest in Indonesia (9%), and in the Middle East, Lebanon, rates are 20%. The highest-lowest ratio between countries, within and across continents, varied from 1.4-2.6. Incidence data is less abundant and more heterogeneous. Age-standardized rates in studies combining hospitalized and ambulatory vertebral fractures are highest in South Korea, USA, and Hong Kong and lowest in the UK. Neither a North-South gradient nor a relation to urbanization is evident. Conversely, the incidence of hospitalized vertebral fractures in European patients ≥50 shows a North-South gradient with 3-3.7-fold variability. In the USA, rates in Whites are approximately 4-fold higher than in Blacks. Vertebral fractures variation worldwide is lower than observed with hip fractures, and some of highest rates are unexpectedly from Asia. Better quality representative studies are needed. We investigate the occurrence of vertebral fractures, worldwide, using published data current until the present. Worldwide, the variation in vertebral fractures is lower than observed for hip fractures. Some of the highest rates are from North America and unexpectedly Asia. The highest-lowest ratio between countries, within and across continents, varied from 1.4-2.6. Better quality representative data is needed.

Endocrinol Metab (Seoul) 2016; 31:433-438.

Abstract
BACKGROUND Osteoporosis in men is markedly underdiagnosed and undertreated despite higher morbidity and mortality associated with fractures. This study aimed to characterize adult Filipino men with osteopenia, osteoporosis and prevalent fractures. METHODS A cross-sectional study of 184 Filipino men ≥50 years screened for bone mineral density was performed. Age, weight, body mass index (BMI), Osteoporosis Self-Assessment Tool for Asians (OSTA) score, smoking status, family history of fracture, diabetes mellitus, physical inactivity, and T-score were considered. RESULTS Of the 184 patients, 40.2% and 29.9% have osteopenia and osteoporosis. Sixteen (21.6%) and 18 (32.1%) osteopenic and osteoporotic men have fragility hip, spine, or forearm fractures. Men aged 50 to 69 years have the same risk of osteoporosis and fractures as those ≥70 years. While hip fractures are higher in osteoporotic men, vertebral fractures are increased in both osteopenic and osteoporotic men. Mere osteopenia predicts the presence of prevalent fractures. A high risk OSTA score can predict fracture. A BMI <21 kg/m² (P<0.05) and current smoking are associated with osteoporosis. CONCLUSION A significant fraction of Filipino men with osteopenia and osteoporosis have prevalent fractures. Our data suggest that fractures occur in men <70 years even before osteoporosis sets in. Low BMI, high OSTA score, and smoking are significant risk factors of osteoporosis.

Abstract
The greatest burden of hip fractures around the world is expected to occur in East Asia, especially China. However, there is a relative paucity of information on the epidemiology and burden of fractures in East Asia. Osteoporosis is greatly under-diagnosed and under-treated, even among the highest-risk subjects who have already suffered fractures. The accessibility to bone densitometry, the awareness of the disease by professionals and the public, and the use and reimbursement of drugs are some of the areas which need improvement especially. Cost-effective analysis on screening strategy and intervention thresholds based on local epidemiology data and economic status are available only in Japan. In addition, clinical risk factor models for the assessment of fracture probability may be ethnic specific. Further research is needed to develop a cost-effective risk assessment strategy to identify high-risk individuals for screening and treatment based on local data. Moreover, inadequate calcium and vitamin D intake is still an issue faced by this region.

Abstract
Some vertebral fractures come to clinical attention but most do not. This cross-sectional survey aimed to clarify the associations of self-reported height loss and kyphosis with vertebral fractures. We enrolled 407 women aged 60-92 years who visited our orthopaedic clinic between June and August 2014 in our study. Inclusion criteria were lateral radiography followed by completion of a structured questionnaire in this study. The primary outcome was vertebral fracture diagnosed on lateral radiography and graded using a semiquantitative grading method, from SQ0 (normal) to SQ3 (severe). Self-reported kyphosis was defined as none, mild to moderate, severe. Self-reported height loss was defined as <4 cm or ≥4 cm. Number of SQ1 fracture was associated only with kyphosis. Self-reported severe kyphosis was significantly associated with increased numbers of ≥SQ2 vertebral fractures (p = 0.007). Height loss ≥4 cm was significantly associated with increased ≥SQ2 grade fractures (p < 0.001). Odds ratios (ORs) for fractures associated with mild-to-moderate and severe kyphosis were 2.1 [95% confidence interval 1.4 to 3.3) and 4.2 (1.8 to 9.5), respectively. OR for fractures associated with height loss ≥4 cm was 2.3 (1.4 to 3.7). Self-reported kyphosis may be useful for identifying Japanese women aged ≥60 years who have undetected vertebral fractures.

Abstract
The purpose of the study was to study the relationship of morphometric vertebral fractures with bone mineral density (BMD) in Indian women older than 50 yr. Four hundred fifteen healthy Indian women older than 50 yr (mean age: 62.8 yr) underwent lateral X-rays of the lumbar and thoracic spine. Genant's semiquantitative method was used to diagnose and classify morphometric vertebral fractures. BMD was measured by DXA at lumbar spine and total hip. Recruited subjects underwent anthropometric, biochemical, and hormonal evaluation. Vertebral fractures were present in 17.1% (95% confidence interval: 13.5, 20.8) subjects. Prevalence of osteoporosis based on BMD was 35.7%. By adding those with prevalent fractures, the number of women requiring therapy for osteoporosis would increase to 46.5%. The BMD measured at femur neck, total hip, and lumbar spine (L1eL4) was not found to be lower in women with vertebral fractures as compared with those without fractures. BMD was not found to be lower in women with vertebral fractures as compared with those without fractures. Significant number of additional subjects with BMD in the normal or osteopenic range become eligible for osteoporosis treatment when presence of vertebral fracture is used as an independent indication for such treatment.

Abstract
Treatment with anti-inflammatory glucocorticoids is associated with osteoporosis. Many of the treated patients are postmenopausal women, who even without treatment have an increased risk of osteoporosis. Lymphocytes have been shown to play a role in postmenopausal and arthritis-induced osteoporosis, and they are targeted by glucocorticoids. The aim of this study was to investigate the mechanisms behind effects of glucocorticoids on bone during health and menopause, focusing on lymphocytes. Female C57BL/6 or SCID mice were therefore sham-operated or ovariectomized and 2 weeks later treatment with dexamethasone (dex), the nonsteroidal anti-inflammatory drug carprofen, or vehicle was started and continued for 2.5 weeks. At the termination of experiments, femurs were phenotyped using peripheral quantitative computed tomography and high-resolution micro-computed tomography, and markers of bone turnover were analyzed in serum. T and B lymphocyte populations in bone marrow and spleen were analyzed by flow cytometry. Dex-treated C57BL/6 mice had increased trabecular bone mineral density, but lower cortical content and thickness compared with vehicle-treated mice. The dex-treated mice also had lower levels of bone turnover markers and markedly decreased numbers of spleen T and B lymphocytes. In contrast, these effects could not be repeated when mice were treated with the nonsteroidal anti-inflammatory drug carprofen. In addition, dex did not increase trabecular bone in ovariectomized SCID mice lacking functional T and B lymphocytes. In contrast to most literature, the results from this study indicate that treatment with dex increased trabecular bone density, which may indicate that this effect is associated with corticosteroid-induced alterations of the lymphocyte populations.

Abstract
Purpose To systematically review the literature describing the efficacy, effectiveness, and safety of raloxifene for postmenopausal Japanese women with osteoporosis or low bone mass (osteopenia). Materials and methods Medline via PubMed and Embase was systematically searched using prespecified terms. Retrieved publications were screened and included if they described randomized controlled trials or observational studies of postmenopausal Japanese women with osteoporosis or osteopenia treated with raloxifene and reported one or more outcome measures (change in bone mineral density [BMD]; fracture incidence; change in bone-turnover markers, hip structural geometry, or blood–lipid profile; occurrence of adverse events; and change in quality of life or pain). Excluded publications were case studies, editorials, letters to the editor, narrative reviews, or publications from non-peer-reviewed journals; multidrug, multicountry, or multidisease studies with no drug-, country-, or disease-level analysis; or studies of participants on dialysis. Results Of the 292 publications retrieved, 15 publications (seven randomized controlled trials, eight observational studies) were included for review. Overall findings were statistically significant increases in BMD of the lumbar spine (nine publications), but not the hip region (eight publications), a low incidence of vertebral fracture (three publications), decreases in markers of bone turnover (eleven publications), improved hip structural geometry (two publications), improved blood–lipid profiles (five publications), a low incidence of hot flushes, leg cramps, venous thromboembolism, and stroke (12 publications), and improved quality of life and pain relief (one publication). Conclusion Findings support raloxifene for reducing vertebral fracture risk by improving BMD and reducing bone turnover in postmenopausal Japanese women with osteoporosis or osteopenia. Careful consideration of fracture risk and the risk–benefit profile of antiosteoporosis medications is required when managing patients with osteoporosis.

Abstract
The FRAX tool has been used to determine possible thresholds for therapeutic intervention; however, there are no FRAX-based intervention thresholds available for China, we proposed that the 10-year probability of major osteoporotic fracture and hip fracture of about 4.0 and 1.3%, respectively, may be acceptable intervention thresholds for central south Chinese postmenopausal women.

Abstract
Background The issue of osteoporosis-induced fractures has attracted the world’s attention. Postmenopausal women are particularly at risk for this type of fracture. The nonmedicinal intervention for postmenopausal women is mainly exercise. Whole body vibration (WBV) is a simple and convenient exercise. There have been some studies investigating the effect of WBV on osteoporosis; however, the intervention models and results are different. This study mainly investigated the effect of high-frequency and high-magnitude WBV on the bone mineral density (BMD) of the lumbar spine in postmenopausal women. Methods This study randomized 28 postmenopausal women into either the WBV group or the control group for a 6-month trial. The WBV group received an intervention of high-frequency (30 Hz) and high-magnitude (3.2 g) WBV in a natural full-standing posture for 5 minutes, three times per week, at a sports center. Dual-energy X-ray absorptiometry was used to measure the lumbar BMD of the two groups before and after the intervention. Results Six months later, the BMD of the WBV group had significantly increased by 2.032% (P=0.047), while that of the control group had decreased by 0.046% (P=0.188). The comparison between the two groups showed that the BMD of the WBV group had increased significantly (P=0.016). Conclusion This study found that 6 months of high-frequency and high-magnitude WBV yielded significant benefits to the BMD of the lumbar spine in postmenopausal women, and could therefore be provided as an alternative exercise.

Number and severity of prevalent vertebral fractures and the risk of subsequent vertebral fractures in Japanese women with osteoporosis: results from the minodronate trial. J Bone Miner Metab 2013; 31:544-50.

Abstract
The aim was to evaluate the risk of new vertebral fractures with the increasing number and severity of prevalent vertebral fractures in women who received placebo or minodronate in a post hoc analysis of a 2-year randomized, double-blind, placebo-controlled study. The subjects were women aged 55-80 years old with 1-5 fragility fractures between the T4 and L4 vertebrae and bone mineral density <80 % of the young adult mean. A total of 704 subjects were randomized to take minodronate 1 mg (n = 359) or placebo (n = 345) once a day for 24 months. In the placebo group, the risk of incident vertebral fractures during the 2-year observational period was significantly related to the number and severity of prevalent vertebral fractures at baseline. The number of prevalent vertebral fractures was an independent risk factor for incident vertebral fracture in multivariate analysis. The relative risk reductions of vertebral fractures by minodronate treatment were 45.2, 61.1, and 64.2 % for patients with 1, 2, and ≥3 prevalent vertebral fractures, respectively, and 87.8, 64.6, and 50.1 % for patients with mild, moderate, and severe prevalent vertebral fractures, respectively. In conclusion, the number of prevalent vertebral fractures is an independent risk factor for incident vertebral fracture and minodronate reduces the fracture risk even in patients at a higher risk for fracture.

Abstract
Osteoporosis is a skeletal disorder characterized by loss of bone mass, decreased bone strength, and an increased risk of bone fracture. The disease progresses with age, especially in postmenopausal women. Japan is one of the most rapidly aging societies worldwide. Japanese individuals over 65 years of age constituted 23.0% of the population in 2010 and 25.1% to 25.2% as of 2013. The estimated number of people with osteoporosis in Japan is currently 13 million. Bisphosphonates increase bone mineral density by inhibiting osteoclast-mediated bone resorption, thereby reducing the risk of fractures. Alendronate sodium hydrate (alendronate) is a bisphosphonate that potently inhibits bone resorption and is used to treat osteoporosis. Sufficient water is required to take an alendronate oral tablet; insufficient water could result in digestive system diseases, such as esophageal ulceration. Elderly patients with swallowing difficulty may choke on the tablet. Taking a tablet with oral jelly is a method to prevent digestive system disease and reduce the choking hazard. Once-weekly alendronate oral jelly was approved in 2012 by the Ministry of Health, Labour, and Welfare of Japan as the world's first drug for osteoporosis in a jelly formulation. It consists of a jelly portion and an air portion. The jelly formulation is smoothly discharged by pushing the air portion. Therefore, elderly patients with physical disabilities are able to easily take all of the jelly formulation from the package. In this review, this new formulation of alendronate sodium hydrate (oral jelly) is introduced and discussed in terms of osteoporosis treatment. This new formulation provides an alternative so that patients may select a method of dosing tailored to their preferences. Management of osteoporosis involves assessing fracture risk and preventing fractures. Higher adherence to the treatment of patients with osteoporosis and prevention of osteoporotic fractures are issues to be resolved.

Greater Skeletal Gains in Ovary Intact Rats at Maturity Are Achieved by Supplementing a Standardized Extract of Butea monosperma Stem Bark that Confers Better Bone Conserving Effect following Ovariectomy and Concurrent Treatment Withdrawal. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:519387. [PMID: 23710224 PMCID: PMC3655608 DOI: 10.1155/2013/519387] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/27/2012] [Accepted: 03/13/2013] [Indexed: 12/17/2022]
Abstract
With a longitudinally designed study, we tested whether an acetone soluble fraction (ASF) from the stem bark of Butea monosperma resulted in maximizing bone gain in rats during growth and maturation and thus protected against osteopenia following ovariectomy (OVx) with concomitant treatment withdrawal. Female rats at weaning were given ASF (100 mg/kg/d) or vehicle for 12 weeks, and baseline skeletal parameters (micro-CT) and total plasma antioxidant status (TAS) were measured. At this stage, one group was OVx and the other group was sham operated. Vehicle group (untreated) after OVx was given E2 or continued with vehicle (OVx control). ASF group after OVx was given vehicle (ASF withdrawn, ASFW). After another 12 weeks, all groups were killed and various skeletal parameters were determined. ASF resulted in substantially better skeletal parameters and higher plasma TAS over control at maturity. Rats treated with ASF before OVx had reduced rates of bone loss compared to OVx control. Twelve weeks after OVx, the ASFW group exhibited better trabecular microarchitectural preservation, bone turnover profiles, increased cortical deposition, and biomechanical strength over the OVx control, and the effects were comparable to OVx + E2 group. ASF supplementation during skeletal growth could maximize bone accrual and could confer increased resistance to post-OVx osteopenia despite treatment withdrawal.

Prevalence and risk factors of vertebral fracture in female Japanese patients with systemic lupus erythematosus. Mod Rheumatol 2012; 23:765-73.

Abstract
OBJECTIVE We examined the prevalence and risk factors of vertebral fracture in female Japanese patients with systemic lupus erythematosus (SLE). METHODS We performed lateral radiographs of the thoracic and lumbar spine and bone mineral density (BMD) measurements and collected demographic, lifestyle, clinical, and treatment characteristics of 52 SLE patients. Vertebral fractures were defined as a >20% reduction of vertebral body height. Odds ratios (ORs) and their 95% confidence intervals (CIs) were computed to assess the strength of associations between vertebral fractures and selected factors among SLE patients. RESULTS At least one vertebral fracture was detected in 50% of SLE patients. A history of previous bone fracture was significantly associated with an increased risk of vertebral fractures among SLE patients (adjusted OR = 14.8, 95% CI = 1.62-134; P = 0.017). Daily use of tea or coffee was marginally associated with a decreased risk of vertebral fractures among SLE patients (adjusted OR = 0.11, 95% CI = 0.01-1.01; P = 0.051). CONCLUSION The high prevalence of vertebral fracture in SLE patients (50%) indicates that we need to assess the lateral spine radiograph in more female Japanese SLE patients regardless of BMD and use of corticosteroids, although additional studies are warranted to confirm the findings suggested in this study.
