In this study of postmenopausal women in Malaysia, total adiposity was inversely associated with total BMD, while regional associations varied. No differences were detected across Malay, Chinese, and Indian ethnicities. Low BMD contributes substantially to morbidity and mortality, and increasing adiposity levels globally may be contributing to this.

Purpose: To investigate associations of total and regional adiposity with bone mineral density (BMD) among a multi-ethnic cohort of postmenopausal women.

Methods: Dual X-ray absorptiometry (DXA) imaging was undertaken for 1990 postmenopausal women without prior chronic diseases (30% Malay, 53% Chinese, and 17% Indian) from The Malaysian Cohort (TMC). The strength of the associations between standardized total and regional body fat percentages with total and regional BMD was examined using linear regression models adjusted for age, height, lean mass, ethnicity, education, and diabetes. Effect modification was assessed for ethnicity.

Results: Women with a higher total body fat percentage were more likely to be Indian or Malay. Mean (SD) BMD for the whole-body total, lumbar spine, leg, and arm were 1.08 (0.11), 0.96 (0.15), 2.21 (0.22), and 1.36 (0.12) g/cm², respectively. Total body and visceral fat percentage were inversely associated with total BMD (- 0.02 [95% CI - 0.03, - 0.01] and - 0.01 [- 0.02, - 0.006] g/cm² per 1 SD, respectively). In contrast, subcutaneous and gynoid fat percentages were positively associated with BMD (0.007 [0.002, 0.01] and 0.01 [0.006, 0.02] g/cm², respectively). Total body fat percentage showed a weak positive association with lumbar BMD (0.01 [0.004, 0.02]) and inverse associations with leg (- 0.04 [- 0.06, - 0.03]) and arm (- 0.02 [- 0.03, - 0.02]) BMD in the highest four quintiles. There was no effect modification by ethnicity (p_hetero > 0.05).

Conclusion: Total adiposity was inversely associated with total BMD, although regional associations varied. There was no heterogeneity across ethnic groups suggesting adiposity may be a risk factor for low BMD across diverse populations.

This study investigated treatment trends and major adverse events in patients hospitalized for osteoporotic vertebral fracture (OVF). The frequency of surgical interventions for OVF increased significantly, but this did not decrease major adverse events. The findings underscore the necessity for reevaluating OVF management strategies.

Purpose: Osteoporotic vertebral fracture (OVF) is a common condition in the aging population, often leading to increased morbidity and mortality. Here, we analyzed treatment trends and incidence of major adverse events in patients hospitalized for OVF.

Methods: We conducted a cross-sectional descriptive study, using a large Japanese hospital administrative database. The cohort included hospitalized patients aged 65 years or older, admitted for OVF from January 2015 to December 2021. The primary outcomes were the trend in the proportion of the patients undergoing surgery for OVF and the incidence of major adverse events within 30 days of admission. As a secondary outcome, we evaluated the trend in hospitalization costs.

Results: The study cohort consisted of 14,714 patients, with a mean age of 82.4 years. There was a significant increase in surgical interventions for OVF, from 3.7% of patients in 2015 to 9.8% in 2021 (p < 0.001). The incidence of major adverse events remained unchanged, with a risk ratio of 1.09 (95% confidence interval, 0.88 to 1.35) in 2021 compared to 2015. Average hospitalization costs increased significantly, from $7,570.6 (SD 6,047.0) in 2015 to $9,502.9 (SD 7,231.5) in 2021 (p < 0.001).

Conclusion: Despite a significant increase in the proportion of surgical intervention for OVF, no reduction in the risk of major adverse events was observed between 2015 and 2021. Surgeons and policy makers need to interpret these findings and work towards an optimized approach to the management of OVF in the aging population.

The current study investigated subsequent fracture risk following a forearm fracture in three country of birth categories: Norway, Europe and North America, and other countries. Subsequent fracture risk was modestly higher in Norwegian-born individuals compared to the two other groups. Secondary fracture prevention should be recommended regardless of country background.

Background: Fracture risk is higher in patients with a previous fracture, but whether subsequent fracture risk differs by origin of birth is unknown. This study explores subsequent fracture risk in patients with an index forearm fracture according to region of birth.

Methods: Nationwide data on forearm fractures in patients ≥ 18 years in 2008-2019 were obtained from the Norwegian Patient Registry and Statistics Norway. Index fractures were identified by ICD-10 code S52, whereas subsequent fractures included any ICD-10 fracture code. Data on country of birth were from Statistics Norway and included three regional categories: (1) Norway, (2) other Europe and North America and (3) other countries. Direct age standardization and Cox proportional hazard regression were used to analyse the data.

Results: Among 143,476 individuals with an index forearm fracture, 35,361 sustained a subsequent fracture. Norwegian-born forearm fracture patients had the highest subsequent fracture rates (516/10,000 person-years in women and 380 in men). People born outside Europe and North America had the lowest rates (278/10,000 person-years in women and 286 in men). Compared to Norwegian-born individuals, the hazard ratios (HRs) of subsequent fracture in individuals from Europe and North American were 0.93 (95% CI 0.88-0.98) in women and 0.85 (95% CI 0.79-0.92) in men. The corresponding HRs in individuals from other countries were 0.76 (95% CI 0.70-0.84) in women and 0.82 (95% CI 0.74-0.92) in men.

Conclusion: Individuals born outside Norway had a lower subsequent fracture risk than Norwegian-born individuals; however, subsequent fracture risk increased with age in all groups. Our results indicate that secondary fracture prevention should be recommended regardless of region of origin.

Summary

The association between live microbe intake and osteoporosis in postmenopausal women remains unknown. The research findings indicated that an increased intake of live microbes through dietary sources was associated with a low prevalence of osteoporosis among postmenopausal women.

Purpose

To investigate the relationship between the consumption of live microbes in the diet and osteoporosis in postmenopausal women.

Methods

A cross-sectional investigation using data obtained from the National Health and Nutrition Examination Survey was conducted. Participants were classified into three groups by using the dietary live microbe classification system developed by Sanders. Dual x-ray absorptiometry was used to measure body mineral density, and osteoporosis was diagnosed according to the World Health Organization criteria. We conducted a crude and adjusted multivariate logistic regression analysis, and utilized the restricted cubic splines model to assess the correlation between the consumption of live microbes in the diet and osteoporosis in postmenopausal women.

Results

A total of 1378 women who had undergone menopause were enrolled in the study. After controlling for potential covariates, individuals with a high consumption of live microbes in their diet exhibited a notably low prevalence of osteoporosis in comparison to those with a low intake of dietary live microbes (odd ratio: 0.46, 95% confidence interval: 0.23, 0.93, P = 0.03). Subgroup analysis showed the stability of the results, and restricted cubic splines showed an approximate L-shape curve.

Conclusions

In this research, a higher consumption of live microbes in the diet was linked to a low prevalence of osteoporosis in postmenopausal women.

Summary

Fracture Liaison Service is a coordinator-based model effective in addressing the fragility fracture care gap. This study found that the service was feasible in Malaysia and could improve the delivery of secondary fracture prevention. Local adaptations and reactive responses addressed challenges, enhancing feasibility.

Purpose

To assess the feasibility of a Fracture Liaison Service in Malaysia and to benchmark our service against the International Osteoporosis Foundation Best Practice Framework.

Methods

This feasibility study was conducted at a tertiary hospital in Malaysia from March 2021 to March 2022. Patients aged ≥ 50 years admitted with fragility fractures were recruited. Excluded were those with poor prognosis or transferred out from the hospital during admission. Patients were screened, assessed, and followed up at months 4 and 12 post-fracture presentations. Data was collected using Microsoft Excel and the REDCap database. The feasibility of the Fracture Liaison Service was evaluated using the typology of feasibility.

Results

A total of 140 patients (female (93/140, 66.4%), median age 77 (IQR 72, 83), hip fractures (100/140, 65.8%)) were recruited into the Fracture Liaison Service. The recruitment rate was (140/215, 65.1%), as some patients were “missed” due to the COVID-19 pandemic. The completion rate was high (101/114, 88.6%). Among those indicated for antiosteoporosis medication, 82/100 (82%) were initiated on treatment. Various “Best Practice Standards,” such as patient evaluation (140/140, 100%), fall prevention (130/140, 92.9%), and medication review standards (15/15, 100%) were high. Complicated referral pathways, inexperienced staff, lack of resources, and communication issues were some of the barriers identified while implementing the Fracture Liaison Service. Challenges were overcome by modifying the service workflow and coordinating with different departments.

Conclusion

The Fracture Liaison Service was found to be feasible in Malaysia. It demonstrated promise in improving bone health management; however, several changes were needed to adapt the service to suit our environment.

This study assessed osteoporosis knowledge and awareness among multiple sclerosis patients. The findings reveal a concerning lack of knowledge and awareness regarding osteoporosis, emphasizing the necessity for educational interventions to enhance early detection and mitigate complications within this particular patient group.

Aim: To assess the knowledge and awareness of osteoporosis in Turkish multiple sclerosis (MS) patients.

Material-methods: Three hundred twenty-five patients were asked to fill out the osteoporosis awareness scale (OAS), which has a scoring range of 31-124, and the revised osteoporosis knowledge test (R-OKT), which has a score range of 0-32. Fall risk assessment for patients was conducted using the timed up-and-go test (high risk: > 30, moderate risk: 29-20, low risk: 14-19, and no risk: < 13 s).

Results: An average score of 59.42 ± 19.63(31%) on the OAS and 14.99 ± 5.39 (47%) on the R-OKT was detected. No difference was found in R-OKT scores between genders, education levels, and patients with different fall risks and between genders and education levels in OAS scores. Patients with low, medium, and high fall risks exhibited higher OAS scores compared to those without any fall risk (p = 0.006, p < 0.001, and p < 0.001, respectively). No correlation was found between gender and education level with OAS and R-OKT scores and between the R-OKT scores and the risk of falls. There was a weak correlation between the OAS scores and an increased risk of falls (r = 0.269, p < 0.001). No differences between the age groups regarding OAS and R-OKT scores were observed.

Conclusions: Turkish MS patients have inadequate knowledge and low awareness of OP compared to the healthy population. Urgent action is warranted to educate and support individuals with MS, implementing targeted interventions and awareness campaigns to improve early detection and prevent osteoporosis-related complications.

This study explored why some elderly females do not adhere to their bone density tests. It found that factors like age, race, marital status, insurance type, social vulnerability index, and vaccination status influence completion of these tests. Addressing these differences could improve the management of bone health in older adults.

Purpose: This study investigated factors influencing the cancellation of dual-energy x-ray absorptiometry (DXA) scans among females aged 65 and above during the COVID-19 pandemic.

Methods: Utilizing a dataset of 19,066 females from 2021 to 2023, the research employed chi-squared tests and logistic regression analyses to examine demographic, socio-economic, and health-related determinants of DXA scan adherence.

Results: Key findings revealed that younger seniors, White patients, married individuals, those with commercial/private or Medicare insurance, and vaccinated persons were more likely to complete DXA scans. In contrast, Asian and African American females, along with those from higher Social Vulnerability Index areas, showed lower completion rates.

Conclusion: These results highlight the need for tailored strategies to improve osteoporosis screening adherence, focusing on identified demographic groups to enhance overall healthcare outcomes in osteoporosis management.

The impact of milk on bone health in rural preschoolers is under-researched. This study, through a clinical trial and a meta-analysis, finds that milk supplementation enhances forearm and calcaneus bone acquisition in children, supporting the benefits of daily milk consumption.

Purpose: This study evaluated the impact of dairy supplementation on bone acquisition in children's limbs through a cluster-randomized controlled trial and a meta-analysis.

Methods: The trial involved 315 children (4-6 year) from Northwest China, randomized to receive either 390 ml of milk daily (n = 215) or 20-30 g of bread (n = 100) over 12 months. We primarily assessed bone mineral density (BMD) and content (BMC) changes at the limbs, alongside bone-related biomarkers, measured at baseline, the 6th and 12th months. The meta-analysis aggregated BMD or BMC changes in the forearm/legs/calcaneus from published randomized trials involving children aged 3-18 years supplemented with dairy foods (vs. control group).

Results: Of 278 completed the trial, intention-to-treat analysis revealed significant increases in BMD (4.05% and 7.31%) and BMC (4.69% and 7.34%) in the left forearm at the 6th and 12th months in the milk group compared to controls (P < 0.001). The calcaneus showed notable improvements in BMD (2.01%) and BMC (1.87%) at 6 months but not at 12 months. Additionally, milk supplementation was associated with beneficial changes in bone resorption markers, parathyroid hormone (- 12.70%), insulin-like growth factor 1 (6.69%), and the calcium-to-phosphorus ratio (2.22%) (all P < 0.05). The meta-analysis, encompassing 894 children, indicated that dairy supplementation significantly increased BMD (SMD, 0.629; 95%CI: 0.275, 0.983) and BMC (SMD, 0.616; 95%CI: 0.380, 0.851) (P < 0.05) in the arms, but not in the legs (P > 0.05).

Conclusion: Milk supplementation significantly improves bone health in children's forearms, underscoring its potential as a strategic dietary intervention for bone development. Trial registration NCT05074836.
