Area Change

Bone mineral density (aBMD) is equivalent to bone mineral content (BMC) divided by area. We rechecked the significance of aBMD changes in aging by examining BMC and area separately. Subjects were 1167 community-dwelling Japanese men and women, aged 40–79 years. ABMDs of femoral neck and lumbar spine were assessed by DXA twice, at 6-year intervals. The change rates of BMC and area, as well as aBMD, were calculated and described separately by the age stratum and by sex. In the femoral neck region, aBMDs were significantly decreased in all age strata by an increase in area as well as BMC loss in the same pattern in both sexes. In the lumbar spine region, aBMDs decreased until the age of 60 in women, caused by the significant BMC decrease accompanying the small area change. Very differently in men, aBMDs increased after their 50s due to BMC increase, accompanied by an area increase. Separate analyses of BMC and area change revealed that the significance of aBMD changes in aging was very divergent among sites and between sexes. This may explain in part the dissociation of aBMD change and bone strength, suggesting that we should be more cautious when interpreting the meaning of aBMD change.

Macro And Micronutrients

ABSTRACT Background Macro- and micronutrients, such as proteins, vitamin D, and calcium (Ca), are important dietary factors that can modify bone mineral density (BMD). Genetic factors can interact with diet, affecting an individual's predisposition to osteoporosis. Objectives This study aimed to evaluate the associations between macro- and micronutrient intakes and BMD in Mexican postmenopausal women, and their interactions with genetic polymorphisms involved in the vitamin D metabolic pathway. Methods We analyzed data from 317 postmenopausal women from the Health Workers Cohort Study, a longitudinal cohort studied in Cuernavaca, Mexico. Postmenopausal women participated in 2 data collection waves (2004–2006 and 2010–2011), with a mean time of 6.4 years. Dietary intake was assessed with a semi-quantitative FFQ. BMD (femoral neck, hip, and lumbar spine) was measured by DXA. Hybrid mixed-effects regression models were used to assess the associations of dietary macro- and micronutrients on BMD, after adjusting for confounding factors and for diet and single nucleotide polymorphism interactions. Results At baseline, the median age was 57 years (IQR, 50–64). Mean femoral neck, hip, and lumbar spine BMDs decreased over time. We observed statistically significant longitudinal associations for diet (Ca, vitamin D, magnesium, phosphorus, and protein intake) and BMD. Increases of vitamin D, Ca, and protein intakes by 1 SD were associated with mean increases in the femoral neck BMD (0.083 SD, 0.064 SD, and 0.130 SD, respectively). Multiple significant interactions were identified between several loci (CYP2R1, CYP24A1, CYP27B1, VDR, and DHCR7/NADSYN1) and diet for BMDs (femoral neck, hip, and lumbar spine), mainly for protein intake. Conclusions Our data support associations of vitamin D, Ca, protein, phosphorous, and magnesium consumption with BMD in Mexican postmenopausal women and suggest possible gene-diet interactions. These results could facilitate future personalized nutrition recommendations to help prevent low BMD.

Abstract Aim To evaluate the quality of life in postmenopausal women and its correlation with bone mineral density. Study design Cross-sectional study. Duration of the study October 2012 to September 2014. Settings Physical Medicine and Rehabilitation Department, Regional Institute of Medical Sciences, Imphal. Study population Postmenopausal women who attended the department during the study period. Materials and Methods Quality of life was assessed using WHOQOL-BREF questionnaire, a validated brief version of the WHOQOL-100. Bone mineral density (BMD) in the lumbar spine, femoral neck and trochanter were measured using dual energy x-ray absorptiometry (DEXA) scan – GE Lunar model. Results A total of 125 patients were studied. The mean t-scores in lumbar spine, femoral neck and trochanter were -2.550 ± 1.209, -1.831 ± 0.921 and -1.621 ± 1.064 respectively. The mean BMD (g/cm2) in lumbar spine, femoral neck and trochanter were 0.867 ± 0.144, 0.789 ± 0.131 and 0.682 ± 0.139 respectively. The mean overall WHOQOL score was 57.68±10.07. There were statistically significant positive association of WHOQOL score with the BMDs in lumbar spine, femoral neck and trochanter (p < 0.05). Multivariate regression showed significant relation of overall WHOQOL score with BMD lumbar spine (b=0.229; R2=0.119), BMD femoral neck (b=0.285; R2=0.129), and BMD trochanter (b=0.245; R2=0.119). Conclusion BMDs in the lumbar spine, femoral neck and trochanter had a positive correlation with quality of life scores. BMD also had a good predictive value in determining the quality of life in postmenopausal women.

Background: No studies to date have compared bone mineral density (BMD) changes after epidural steroid injection (ESI) between postmenopausal patients taking antiosteoporotic medication and those who are not. Objective: The aim of the present study was to analyze the relationship between ESI and BMD changes in postmenopausal patients according to antiosteoporotic medication use. Study Design: Retrospective analysis. Setting: Department of Anesthesiology and Pain Medicine at Asan Medical Center, Korea. Methods: We retrospectively analyzed postmenopausal women who underwent ESI using dexamethasone. All women had received a diagnosis of lumbar spinal stenosis and their BMD had been measured before and after treatment. BMD was evaluated by dual-energy x-ray absorptiometry at the lumbar spine, femoral neck, femoral trochanter, and total femur, and was recorded as absolute g/cm2 and T-scores. A total of 126 patients were included in the final analysis. ESI patients were grouped as follows: group 1 (n = 74) ESI patients who took antiosteoporotic medication; group 2 (n = 52) ESI patients who did not take antiosteoporotic medication. Results: In group 1, there were no significant differences between baseline and post-treatment BMD absolute values (g/cm2) in the lumbar spine, femoral neck, femoral trochanter, and total femur. In group 2, significant changes in the post-treatment BMD absolute values (g/cm2) from baseline were observed in the femoral neck (–1.48 ± 3.84%), femoral trochanter (–2.80 ± 7.50%), and total femur (–2.23 ± 4.52%), but not in the lumbar spine (–2.23 ± 4.52%). Limitations: This study contained a small sample size, no control group, and no long-term follow-up of the BMD changes after ESI. Conclusions: Our data provide new evidence indicating that ESI causes BMD changes in postmenopausal women who do not take antiosteoporotic medication. Thus, we recommend that prophylactic antiosteoporotic treatment be considered for postmenopausal women who require ESI treatment.

e11604 Background: Adjuvant therapy with aromatase inhibitors (AI) is associated with increased bone loss in postmenopausal women. We assessed changes in bone mineral density (BMD) from baseline to 60 months of treatment in patients receiving anastrozole (ANA) as initial adjuvant therapy with/without oral bisphosphonates (Bis). Methods: Postmenopausal women with endocrine responsive breast cancer receiving ANA as adjuvant therapy at our hospital since 2004 were enrolled in this study. BMD was assessed by dual-energy X-ray absorptiometry at baseline and after 6, 12, 24, 36, 48 and 60 months. Oral Bis (risedronate or alendronate) treatment was initiated when patients were diagnosed as having osteoporosis with a T-score of -2.5 or lower. Results: Fifty-seven patients were enrolled in the study between 2004 and 2011. Patients’ median age was 65 years (range 50~85) and the median follow-up period was 46.3 months (9.6~83.8). Thirty-five patients were administered Bis (risedronate in 27 patients, alendronate in 8 patients). Within 6 months of hormone therapy, BMD decreased by 0.3% from baseline at the lumbar spine and BMD decreased by 1.2% at the femoral neck. However, BMD increased by 2.8% at the lumbar spine and BMD decreased 0.5% at the femoral neck for 60 months of treatment. In patients treated with upfront Bis (n=24), 4.9% BMD increase from baseline was noted at the lumbar spine whereas in those without Bis (n=20) BMD decreased by 4.6% from baseline within 24 months (p=0.0002). Fractures were observed in 4 patients (7.0%), and 1 patient (1.8%) had fragility fracture. Conclusions: Oral Bis prevented ANA-induced bone loss, and upfront treatment of Bis significantly increased BMD at the lumber spine.
