The aim of the study was to investigate the relationship between bone mineral density (BMD) of lumbar spine, femoral neck, trabecular bone score (TBS) and body mass index (BMI), in postmenopausal women with knee osteoarthritis (OA). Materials and methods: The study group comprised 359 postmenopausal women aged 50-89 years. They were divided into 2 groups: I group – 117 postmenopausal women with symptomatic knee OA and II group –242 women with a normal functional activity of knee joints. Analysis of data was performed taking into account their BMD of lumbar spine (L1-L4) and femoral neck, measured by the Dual-energy X-ray absorptiometry (DXA) Hologic (Discovery WI, USA, 2016). TBS of L1-L4 was detected by TBS insight® software (MedImaps, Pessac, France), and BMI classified by World Health Organization (WHO). Results: In postmenopausal women with obesity prevalence of symptomatic knee OA was detected in 41.1% of cases. However, in women with normal BMI knee OA was revealed in 29.0% of women. The highest level of knee OA in obese women aged 70-79 years – 45.8%. According to a chi-squared (χ2) test, a significantly higher level of BMI was detected in postmenopausal women with OA (χ2=5.05, p=0.02). Conclusion: Women with a symptomatic OA had a significantly higher BMD of lumbar spine compared with women who had a normal functional activity of knee. Significant negative correlation were detected between TBS and BMI, and significant positive correlations between lumbar spine BMD and BMI.

Context: Genistein aglycone improves bone metabolism in women. However, questions about the long-term safety of genistein on breast as well as its continued efficacy still remain. Objective: We assessed the continued safety profile of genistein aglycone on breast and endometrium and its effects on bone after 3 yr of therapy. Design: The parent study was a randomized, double-blind, placebo-controlled trial involving 389 osteopenic, postmenopausal women for 24-months. Subsequently, a subcohort (138 patients) continued therapy for an additional year. Patients and Interventions: Participants received 54 mg of genistein aglycone daily (n = 71) or placebo (n = 67). Both treatment arms received calcium and vitamin D3 in therapeutic doses. Main Outcomes: Mammographic density was assessed at baseline, 24 and 36 months by visual classification scale and digitized quantification. BRCA1 and BRCA2, sister chromatid exchange, and endometrial thickness were also evaluated. Lumbar spine and femoral neck bone mineral density were also assessed. Secondary outcomes were biochemical levels of bone markers. Results: After 36 months, genistein did not significantly change mammographic breast density or endometrial thickness, BRCA1 and BRCA2 expression was preserved, whereas sister chromatid exchange was reduced compared with placebo. Bone mineral density increases were greater with genistein for both femoral neck and lumbar spine compared to placebo. Genistein also significantly reduced pyridinoline, as well as serum carboxy-terminal cross-linking telopeptide and soluble receptor activator of NF-κB ligand while increasing bone-specific alkaline phosphatase, IGF-I, and osteoprotegerin levels. There were no differences in discomfort or adverse events between groups. Conclusions: After 3 yr of treatment, genistein exhibited a promising safety profile with positive effects on bone formation in a cohort of osteopenic, postmenopausal women.

Abstract Context Fracture risk in people with type 1 diabetes (T1D) is higher than their peers without diabetes. Objective To compare bone mineral density (BMD) across the lifespan in individuals with T1D and age- and sex-matched healthy controls. Design Cross-sectional. Setting Subjects (5–71 years) with T1D and matched controls from ongoing research studies at Barbara Davis Center for Diabetes. Patients or other participants Participants with lumbar spine BMD by dual X-ray absorptiometry (DXA) were divided into 2 groups: children ≤20 years and adults >20 years. Intervention None. Main outcome measures Comparison of BMD by diabetes status across age groups and sex using a linear least squares model adjusted for age and body mass index (body mass index (BMI) for adults; and BMI z-score in children). Results Lumbar spine BMD from 194 patients with T1D and 156 controls were analyzed. There was no difference in age- and BMI-adjusted lumbar spine BMD between patients with T1D and controls: among male children (least squares mean ± standard error of the mean [LSM ± SEM]; 0.80 ± 0.01 vs 0.80 ± 0.02 g/cm2, P = .98) or adults (1.01 ± 0.03 vs 1.01 ± 0.03 g/cm2, P = .95), and female children (0.78 ± 0.02 vs 0.81 ± 0.02 g/cm2, P = .23) or adults (0.98 ± 0.02 vs 1.01 ± 0.02 g/cm2, P = .19). Lumbar spine (0.98 ± 0.02 vs 1.04 ± 0.02 g/cm2, P = .05), femoral neck (0.71 ± 0.02 vs 0.79 ± 0.02 g/cm2, P = .003), and total hip (0.84 ± 0.02 vs 0.91 ± 0.02, P = .005) BMD was lower among postmenopausal women with T1D than postmenopausal women without diabetes. Conclusion Across age groups, lumbar spine BMD was similar in patients with T1D compared with age- and sex-matched participants without diabetes, except postmenopausal females with T1D had lower lumbar spine, femoral neck, and total hip BMD.

Objective.To assess the relationship between bone mineral density (BMD) and varus deformity arising from bone structural changes caused by knee osteoarthritis (OA) in postmenopausal women.Methods.This cross-sectional study involved 135 consecutive postmenopausal female patients who had varus knee OA and a Kellgren-Lawrence grade ≥ 2. Knee radiographs were obtained with the patient standing on one leg, and subjects were classified into 3 tertile groups according to femorotibial angle, which was taken as a measure of varus knee OA severity. We also measured the 3 subangles that make up the femorotibial angle, and focused on the varus inclination of the tibial plateau. BMD was measured in the lumbar spine, femoral neck, and medial and lateral tibial condyles using dual-energy X-ray absorptiometry. Differences between femorotibial angle tertile groups were assessed, and associations between femorotibial sub-angles and BMD values at various points were evaluated.Results.After adjustment for age and body mass index, there was no significant association between the varus inclination of the tibial plateau and lumbar spine BMD. A weak but statistically significant negative correlation existed between varus inclination of the tibial plateau and BMD at the ipsilateral proximal femur and lateral tibial condyle.Conclusion.Varus inclination of the tibial plateau was significantly more severe in the femorotibial angle tertile 3 group, and in patients with lower BMD in the ipsilateral lower limb. Varus knee OA may result not only from cartilage loss but also from structural changes of the bone.

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.
