Background: Bone mineral density (BMD) measurement is one of the method for making osteoporosis diagnosis. World Health Organization (WHO) recommends the measurement of BMD conducted at antero-posterior lumbar vertebrae, unilateral hip (femur), and radius. However, there was a concern about osteoporosis under diagnosis if the measurement is only conducted at unilateral hip. Some studies found significant differences of BMD between both femur and evidence of the importance to examine both femur in making the diagnosis of osteoporosis. This study aims to determine anydifference between right and left femur BMD measurement and to investigate the bone status result with measurement of BMD of bilateral femur in Hasan Sadikin General Hospital. Methods: A retrospective study was conducted from June to November 2015. Patients who received dual-femur BMD testing using General Electrics (GE) Lunar Prodigy dual-energy x-ray absorptiometry at the DXA Facility in Hasan Sadikin General Hospital,Bandung between January 1, 2006 to December 31, 2014 were included. Statistical analysis performed to assess the difference and the correlation between theBMD of two femurs (g/cm2). T-scores of the subject were implemented into bone status according to WHO Diagnostic Criteria for Osteoporosis.Results: From sixty-one patients included in this study, there were difference bone status resulted from BMD of the femoral neck, Ward’s triangle, trochanter, andtotal hip area between right and left femur, although no statistically significance were found. There was a positive correlation between BMD of right and left femurat all areas of femur. There were 16 subjects (26.1%) showed combination level of bone status (normal, osteopenia, or osteoporosis in one femur).Conclusion: BMD results in each area of the right and left femurs are different.Therefore, performing bilateral hip BMD examination as a routine measurement for makingdiagnosis of osteoporosis is important.Keywords: Bone Mineral Density, Dual-energy X-ray Absorptiometry, Femur, Osteoporosis

With an aging population, osteoporosis is increasingly becoming a public health concern. Bangladesh has a high incidence of osteoporosis and occurs among a relatively younger age group than in the developed world. There are several factors that could be associated with bone mineral density (BMD). We are keen to determine the association with BMD and BMI. The study was carried out on 152 patients who were referred to INMAS for dual energy X- ray absorptiometry (DEXA) measurement of bone mineral density (BMD) during the periods of January 2018 to July 2019. BMD was measured at right femoral neck and lumbar spines. Data about age and sex, BMI were recorded. Reporting was done according to the T score following WHO criteria. Prevalence were compared using chi-squared tests. Among 152 patients, 84.9% were females and 15.1% were males. Results showed for right femur that normal bone density in 91 (59.1%), osteopenia in 54 (35.1%), osteoporosis in 9 (5.8%) and BMD in spine was normal in 57 (37.0%) osteopenia in 44 (28.6%), osteoporosis in 53 (34.4%). About 60% of the study population was normal weight and others were underweighted or overweighed. Status of BMD was associated with BMI in the lumbar spine and femur. In this study group, total 61.2% and 26.3%were found low BMD in spine and right femur respectively. In age group ≥ 60 years, low BMD in spinewas 72.0% that is 42.29% higher compare to below 60 years’ group (50.6%).Correlation of BMI with lumbar spine T score, right femur and left femur T score were measured by Pearson’s correlation coefficient test. Positive significant Pearson’s correlation was observedbetween BMI with spine T score (r = 0.397; p = <0.001), BMI with right femur T score (r = 0.347; p = <0.001) and BMI with left femur T score (r = 0.382; p = <0.001).

Significant Change

Background:Dual energy X-ray absoprtiometry is the reference method to mesure bone mineral density (1). Loss of bone mineral density is significant if it exceeds the least significant change. The threshold value used in general population is 0,03 g/cm2 (2). Patients with obesity are known for having a higher bone mineral density due to metabolism and physiopathology characteristics (3,4).Objectives:The aim of our study was to determine the least significant change in bone densitometry in patients with obesity.Methods:We conducted an interventionnal study in 120 patients with obesity who performed a bone densitometry. We measured twice the bone mineral density at the lumbar spine, the femoral neck and the total hip in the same time (5,6). We determined the least significant change in bone densitometry from each pair of measurements, using the Bland and Altman method. We also determined the least significant change in bone densitometry according to each stage of obesity.Results:The least significant change in bone densitometry in patients with obesity is 0,046g/cm2 at the lumbar spine, 0.069 g/cm2 at the femoral neck and 0.06 g/cm2 at the total hip.Conclusion:The least significant change in bone densitometry in patients with obesity is higher than in general population. These results may improve DXA interpretation in this specific population, and may personnalize their medical care.References:[1]Lees B, Stevenson JC.
