Dietary determinants of post-menopausal bone loss at the lumbar spine: a possible beneficial effect of iron

1. This study examined the influence of brisk walking on skeletal status in post-menopausal women. 2. Subjects were 84 healthy women aged 60–70 years who were previously sedentary and at least 5 years post-menopausal. Subjects were randomly assigned to walking (n = 43) and control (n = 41) groups. Walkers followed a 12-month, largely unsupervised programme of brisk walking. The bone mineral density of the lumbar spine, femoral neck and calcaneus and broadband ultrasonic attention of the calcaneus were measured at baseline and after 12 months. 3. Forty control subjects and 38 walkers completed the study. Walkers built up to 20.4 ± 3.8 min/day (mean ± SD) of brisk walking. Body mass increased in control subjects relative to walkers [mean change (SE) ± 0.9 (0.3) and −0.1 (0.3) kg respectively; P = 0.04]. Predicted maximum oxygen uptake increased in walkers by 2.1 (0.9) ml min−1 kg−1 (P = 0.02). Bone mineral density in the lumbar spine and calcaneus fell in control subjects [–0.005 (0.004) and −0.010 (0.004) g/cm2, respectively] but not in walkers [+0.006 (0.004) and +0.001 (0.004) g/cm2]. The difference in response between groups was significant in the calcaneus (P = 0.04) but not in the lumbar spine (P = 0.08). Mean femoral neck bone mineral density did not change significantly in either group, although changes in walkers were related to the amount of walking completed (r = 0.51, P = 0.001). The change in broadband ultrasonic attenuation of the calcaneus differed between groups [control subjects, −3.7 (0.8); walkers, −0.7 (0.8) dB/MHz; P = 0.01]. 4. Walking decreased bone loss in the calcaneus and possibly in the lumbar spine. It also improved functional capacity and enabled walkers to avoid the increase in body mass seen in control subjects.

Abstract Background To explore the prevalence of bone loss among patients with rheumatoid arthritis (RA) and healthy controls (HC) and further explored the risk factors for osteopenia and osteoporosis of RA patients. Methods A cross-sectional survey was undertaken in four hospitals in different districts in South China to reveal the prevalence of bone loss in patients. Case records, laboratory tests, and bone mineral density (BMD) results of patients were collected. Traditional multivariable logistic regression analysis and two machine learning methods, including least absolute shrinkage selection operator (LASSO) and random forest (RF) were for exploring the risk factors for osteopenia or osteoporosis in RA patients. Results Four hundred five patients with RA and 198 HC were included. RA patients had lower BMD in almost BMD measurement sites than healthy controls; the decline of lumbar spine BMD was earlier than HC. RA patients were more likely to comorbid with osteopenia and osteoporosis (p for trend < 0.001) in the lumbar spine than HC. Higher serum 25-hydroxyvitamin D3 level and using tumor necrosis factor inhibitor in the last year were protective factors; aging, lower body mass index, and increased serum uric acid might be risk factors for bone loss. Conclusions RA patients were more prone and earlier to have bone loss than HC. More attention should be paid to measuring BMD in RA patients aging with lower BMI or hyperuricemia. Besides, serum vitamin D and all three measurement sites are recommended to check routinely. TNFi usage in the last year might benefit bone mass.

Background:Hand osteoarthritis (OA) and its more severe subset erosive hand OA are common causes of pain and morbidity. Some metabolic factors were suggested to be implicated in erosive disease. Few studies investigated differences in systemic bone loss between erosive and non-erosive hand OA.Objectives:To compare the change of bone mineral density (BMD) between patients with erosive and non-erosive hand OA in a two-year longitudinal study.Methods:Consecutive patients with symptomatic HOA fulfilling the American College of Rheumatology (ACR) criteria were included in this study. Erosive hand OA was defined by at least one erosive interphalangeal joint. All patients underwent clinical assessments of joint swelling and radiographs of both hands. DEXA examination of lumbar spine, total femur and femur neck was performed at the baseline and after two years.Results:Altogether, 141patients (15 male) with symptomatic nodal HOA were included in this study and followed between April 2012 and January 2019. Out of these patients, 80 had erosive disease after two years. The disease duration (p<0.01) was significantly higher in patients with erosive compared with non-erosive disease at baseline.Osteoporosis (T-score <-2.5 SD) was diagnosed in 12.5% (9/72) of patients with erosive hand OA and in 8.06% (5/57) of patients with non-erosive hand OA at baseline. BMD was significantly lowered in patients with erosive compared with non-erosive disease at baseline (lumbar spine: 1.05g/cm2 vs. 1.13 g/cm2, p<0.05, total femur: 0.90 g/cm2 vs. 0.97 g/cm2, p<0.01 and femur neck: 0.86 g/cm2 vs. 0.91, p<0.05). T-scores of lumbar spine (-0.96 vs. -0.41 SD, p<0.05), total femur (-0.69 vs. -0.33 SD, p<0.05) and femur neck (-1.14 vs. -0.88 SD, p<0.05) were also significantly lowered in patients with erosive compared with non-erosive disease.Two years, the BMD remained also significantly lowered in patients with erosive compared with non-erosive disease (lumbar spine: 1.05g/cm2 vs. 1.14 g/cm2, p<0.05, total femur: 0.92 g/cm2 vs. 0.97 g/cm2, p<0.05 and femur neck: 0.86 g/cm2 vs. 0.91, p<0.05), which was in agreement with the finding for T-scores of lumbar spine (-1.05 vs. -0.39 SD, p<0.05), total femur (-0.74 vs. -0.34 SD, p<0.01) and femur neck (-1.07 vs. -0.72 SD, p<0.01).Conclusion:These results suggest that patients with erosive hand OA are at higher risk for the development of general bone loss. Over two years patients with erosive disease had significant lower bone mineral density at all measured sites.References:[1]This work was supported by the project AZV no. 18-00542 and MHCR No. 023728.Acknowledgments:Project AZV no. 18-00542 and MHCR No. 023728Disclosure of Interests:Karel Pavelka Consultant of: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Speakers bureau: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Ladislav Šenolt: None declared, Olga Sleglova: None declared, Jiří Baloun: None declared, Olga Růžičková: None declared

The application of medical scanning technologies to archaeological skeletons provides novel insights into the history and potential causes of osteoporosis. The present study investigated bone mineral density (BMD) in medieval skeletons from England and Norway. Comparisons between the two adult populations found no statistically significant differences. This compares with a modern fracture incidence for the femoral neck in women from Norway that is almost three times that in the UK. The pattern of age-related bone loss in medieval men was similar to that seen in men today. In contrast, the pattern in medieval women differed from that of modern young women. On average, medieval women experienced a decrease in BMD at the femoral neck of approximately 23 per cent between the ages of 22 and 35. These losses were partially recovered by age 45, after which BMD values show a decline consistent with post-menopausal bone loss in modern western women. A possible explanation of the rapid decline in BMD in young medieval women is bone loss in connection with pregnancy and lactation in circumstances of insufficient nutrition.
