Abstract Context Bone mineral density (BMD) T-score reference may be updated when the peak BMD of the population is unclear and may need to be updated. Objective To update BMD T-score references using the peak BMD from the most recent National Health and Nutrition Examination Survey (NHANES) data. Design Cross-sectional study. Setting The NHANES 2005-2014. Participants Non-Hispanic white females between the ages 10-40 years (N=1549) were our target population to estimate peak BMD (SD). Individuals aged≥50 years (N=5523) were used to compare the percentages of osteoporosis and low bone mass based on existing and updated BMD T-score references. Main Outcome Measurements: BMD data within the age at attainment of peak BMD±5 years were used to calculate updated BMD T-score references. Results The updated average of BMD (SD) for diagnosing osteoporosis at the femoral neck and lumbar spine were 0.888 g/cm 2 (0.121 g/cm 2) and 1.065 g/cm 2 (0.122 g/cm 2), respectively. The percentages of individuals with osteoporosis at the femoral neck and low bone mass at the femoral neck and lumbar spine based on the updated BMD T-score references were higher than the percentages of people designated with these outcomes under the existing guidelines (P<0.001). However, we observed the opposite pattern for lumbar spine osteoporosis (P<0.001). Conclusions We calculated new BMD T-score references at the femoral neck and lumbar spine. We found significant differences in the percentages of individuals classified as having osteoporosis and low bone mass between the updated and existing BMD T-score references.

Prevalence Of Osteoporosis

Osteoporosis is one of the systemic features of COPD. Aims and objective is to determine the prevalence of osteoporosis in male COPD. In a cross-sectional study, we conducted dual-energy X-ray absorptiometry bone mineral density scans of the femoral neck and lumbar spine and collected data on smoking, duration of COPD, inhaled and oral corticosteroid treatment and staging by pulmonary function tests. We included 60 male patients with COPD, the mean age was 62.4 ± 8.1 years, smoking was 36.8 ± 17.2 smoking-pack year, duration of COPD was 5.4 ± 3.3 years, GOLD stage-III (56.7%) stage-IV (38.3%) and stage-II (5.0%), use of oral steroid (11.7%) inhaled steroid (63.3%) and none (25.0%). Normal bone mineral density was in 6 (10.0%), osteopenia in 24 (40.0%) and osteoporosis in 30 (50%) patients in femoral neck; whereas normal bone mineral density was in 4 (6.7%), osteopenia in 17 (28.3%) and osteoporosis in 39 (65.0%) patients in lumbar spine. Osteoporosis is highly prevalent in male COPD patients in both femoral neck and lumbar spine.Medicine Today 2018 Vol.30(1): 1-4

Patients with hyperparathyroidism (HPT) generally display reduced bone mass due to excessive PTH activity. The effect of parathyroidectomy on bone mass changes in different types of HPT, however, is not well understood. Bone mineral density (BMD) was measured in the distal radius, total body, femoral neck, and lumbar spine by dual energy x-ray absorptiometry in four groups of patients with different hyperparathyroid conditions: primary symptomatic HPT (n = 54), primary asymptomatic (mild) HPT (n = 24), HPT associated with hemodialysis (n = 20), and HPT associated with renal transplant (n = 30). Subsets of patients with primary symptomatic HPT (n= 52), HPT associated with hemodialysis (n = 19), and HPT associated with renal transplant (n = 15) underwent parathyroidectomy, and bone density was measured longitudinally for 3 yr. Patients with primary asymptomatic (mild) HPT did not undergo surgery and were followed prospectively. Before surgery, all groups showed a greater reduction of bone mineral density in cortical bone (distal radius) than in predominantly trabecular bone (lumbar spine). In primary symptomatic HPT, the BMD z-score of the distal radius was −1.80 ± 0.21 (±sem), and the corresponding figures for the total body, femoral neck, and lumbar spine were −0.60 ± 0.15, −0.54 ± 0.14, and −0.53 ± 0.18 compared with those of an age- and sex-matched reference group. In renal HPT BMD z-scores were −2.51± 0.38 (hemodialysis patients) and −2.83 ± 0.43 (renal transplant patients) for the distal radius and between −0.81 and− 1.46 for the other measured sites. After parathyroidectomy, BMD increased by 1–8% at all sites in patients with primary symptomatic HPT and HPT associated with renal transplant. The largest increase in bone mass was observed in patients with HPT associated with hemodialysis, in whom the improvement amounted to 7–23%. In patients with primary HPT and HPT associated with hemodialysis, this increase in bone density resulted in virtual recovery from their preoperative bone loss. The majority of patients with asymptomatic primary HPT disease (n = 21) maintained their bone density during the follow-up period and have not shown evidence of increases in serum calcium or PTH levels, but three patients followed conservatively underwent parathyroidectomy due to progressive deterioration of BMD. We conclude that, regardless of the etiology, a large proportion of HPT patients show reduced bone density. In patients with primary symptomatic HPT and patients with HPT associated with hemodialysis, bone density increases after parathyroidectomy to an extent that largely restores the preoperative bone loss. However, no anabolic effect of parathyroidectomy on bone mass was observed in patients with HPT associated with renal transplant, probably because of their immunosuppressive therapy.

Optimizing bone mass gain during childhood and adolescence may help prevent bone diseases in advanced ages. The aim of this study was to verify the bone mineral density (BMD) and bone mineral content (BMC) in female adolescent’s handball players. This is a cross-sectional study where 68 female adolescents (12–17 years) were allocated into two groups: handball players (n = 29) (HG) and control group (n = 39) (CG). BMC and BMD from total body (TB), total body less head (TBLH), lumbar spine (L1–L4), femoral neck (FN), Ward’s triangle (WT) and respectively Z-scores were measured using dual-energy X-ray absorptiometry (DXA). Sexual maturity, menarche, PHV, time of sun exposure, physical activity level and Calcium and vitamin D intake were assessed. The HG showed significantly higher BMC, BMD as well Z-scores values (p≤0.05) of total body, TBLH, femoral neck, hip and lumbar spine than the CG. When the values were adjusted for lean soft tissue (LST) the HG showed significantly higher BMC of femoral neck (p≤0.05), as well as BMD of TBLH and femoral neck (p≤0.05) and Z-score values all bone sites except hip, than the CG. We conclude that handball players have significantly higher bone mass values compared to group of girls of the same age.

Background This study set out to determine the prevalence of low bone mass following long-term exposure to antiretroviral therapy in Ugandan people living with HIV. Methods A cross-sectional study was conducted among 199 people living with HIV that had been on anti-retroviral therapy for at least 10 years. All participants had dual X-ray absorptiometry to determine their bone mineral density. The data collected included antiretroviral drug history and behavioral risk data Descriptive statistics were used to summarize the data. Inferential statistics were analyzed using multilevel binomial longitudinal Markov chain Monte Carlo mixed multivariate regression modelling using the rstanarm package. Results One hundred ninety nine adults were enrolled with equal representation of males and females. The mean age was 39.5 (SD 8.5) years. Mean durations on anti-retroviral treatment was 12.1 (SD 1.44) years, CD4 cell count was 563.9 cells/mm3. 178 (89.5%) had viral suppression with <50 viral copies/ml. There were 4 (2.0%) and 36 (18%) participants with low bone mass of the hip and lumbar spine respectively. Each unit increase in body mass index was associated with a significant reduction in the odds for low bone mineral density of the hip and lumbar spine. The duration on and exposure to the various antiretroviral medications had no significant effect on the participant’s odds for developing low bone mass. All the coefficients of the variables in a multivariable model for either hip or lumbar spine bone mass were not significant. Conclusion These results provide additional evidence that patients on long term ART achieve bone mass stabilization. Maintaining adequate body weight is important in maintaining good bone health in people on antiretroviral therapy.

Periodontal Index

The association between osteoporosis and periodontal disease (PD) has been revealed by previous studies, but there have been few studies on the association in younger adults. We enrolled a total of 7298 adults aged 40 to 44 who underwent PD screening between 2003 and 2008. Data on quantitative ultrasound for the measurement of bone mineral density (BMD) were collected for the diagnostic criteria of osteopenia and osteoporosis. The Community Periodontal Index (CPI) was measured for defining PD. A multiple logistic regression model was used to assess the effect of low bone mass on the risk of PD. Of 7298 enrollees, 31% had periodontal pockets >3 mm, 36.2% had osteopenia, and 2.1% had osteoporosis. The 39.8% of PD prevalence was high in adults with osteoporosis, followed by 33.3% in osteopenia. A negative association was found between BMD and CPI value (p < 0.0001). Low bone mass was associated with the risk of PD (adjusted OR: 1.13; 95% CI:1.02–1.26) after adjusting the confounding factors, including age, gender, education level, overweight, smoking status, past history of osteoporosis, and diabetes mellitus. An association between BMD and PD among young adults was found. An intervention program for the prevention of PD and osteoporosis could be considered starting in young adults.
