The Relationship Between Bone Mineral Density Values and Prognostic Nutritional Index As Well As Serum Trace Element Levels in Postmenopausal Women

In women, the menopausal transition is characterized by acid-base imbalance, estrogen deficiency and rapid bone loss. Research into nutritional factors that influence bone health is therefore necessary. In this study, the relationship between nutrient patterns and nutrients important for bone health with bone mineral density (BMD) was explored. In this cross-sectional analysis, 101 participants aged between 54 and 81 years were eligible. Body composition and BMD analyses were performed using dual-energy X-ray absorptiometry (DXA). Nutrient data were extracted from a 3-day diet diary (3-DDD) using Foodworks 9 and metabolic equivalent (MET-minutes) was calculated from a self-reported New Zealand physical activity questionnaire (NZPAQ). Significant positive correlations were found between intakes of calcium (p = 0.003, r = 0.294), protein (p = 0.013, r = 0.246), riboflavin (p = 0.020, r = 0.232), niacin equivalent (p = 0.010, r = 0.256) and spine BMD. A nutrient pattern high in riboflavin, phosphorus and calcium was significantly positively correlated with spine (p < 0.05, r = 0.197) and femoral neck BMD (p < 0.05, r = 0.213), while the nutrient pattern high in vitamin E, α-tocopherol, β-carotene and omega 6 fatty acids was negatively correlated with hip (p < 0.05, r = −0.215) and trochanter BMD (p < 0.05, r = −0.251). These findings support the hypothesis that a nutrient pattern high in the intake of vitamin E, α-tocopherol and omega 6 fatty acids appears to be detrimental for bone health in postmenopausal women.

The Relationship

Background:The relationship between lean mass (LM), fat mass (FM) and bone mineral density (BMD) remains controversial. Some population studies have emphasized the positive association between them, while others have found an inverse relationship. RA patients are characterized by a decrease in muscle mass and an increase in fat mass. Such changes in body composition may be associated with low BMD.Objectives:To study the relationship between BMD, LM and FM in postmenopausal women with RA.Methods:68 postmenopausal women with RA (median age 59 [54; 63] years) were included in the study. BMD and body composition were evaluated using two-energy X-ray absorptiometry. Correlation analysis between body composition parameters and BMD was performed with the Spearman method, correlation coefficients R for p<0.05 are presented.Results:The average L1-L4 BMD was 0,92±0,16 g/cm2, total hip BMD - 0,84±0,15 g/cm2 and femoral neck - 0,73±0,13 g/cm2. 33 (48.5%) women had osteopenia, and 17 (25.0%) - osteoporosis (OP). Low appendicular LM was found in 5 (7.4%) and low appendicular muscle index (appendicular LM/height2, AMI) – in 10 (14.7%) patients. Overfat was revealed in 47 (69.1%) women, but only 20 (29.4%) women had BMI corresponding to obesity. The positive correlations between BMD in L1-L4, total hip and femoral neck regions and body weight (R=0.46, R=0.56 and R=0.50, respectively), trunk fat (R=0.4, R=0.51 and R=0.37, respectively), total FM (R=0.27, R=0.43 and R=0.34, respectively), trunk LM (R=0.55, R=0.54 and R=0.51, respectively), total LM (R=0.51, R=0.50 and R=0.52, respectively), appendicular LM (R=0.31, R=0.29 and R=0.37, respectively) and AMI (R=0.26, R=0.33 and R=0.51, respectively) were found out. In the multivariate linear regression analysis total LM was associated with BMD of lumbar spine (β=0.638, p=0.001) and total hip (β=0.473, p=0.008), and AMI - with femoral neck BMD (β=0.360; p=0.014). We found that FM hadn’t a significant effect on BMD in any region.Conclusion:73.5% of patients with RA had a reduced BMD, and 14.7% women – low AMI. LM was positively associated with BMDs in different regions of interest, but FM had no effect on BMD. Further researches are needed to identify associations between body composition, inflammatory activity and bone health in patients with RA.Disclosure of Interests:None declared

The Relationship

Objective: To demonstrate the relationship between anemia and complete blood count (CBC) parameters with bone mineral density (BMD) in postmenopausal women. Materials and Methods: A cross-sectional chart-review study was conducted between November 2017 and June 2019. Three hundred twenty-four postmenopausal women aged 50 years or older who had BMD and CBC results were included in the present study. Results: The prevalence of osteopenia and osteoporosis diagnosed by T-score were 53.1% and 32.7%, respectively. Simple and multiple linear regression analyses showed that no association between CBC parameter with BMD except basophil count, which was negatively associated with BMD (p=0.011). There was no correlation between anemia and BMD status (p=0.168). Conclusion: CBC parameters such as hemoglobin or white blood cell count were not statistically correlated with BMD. This is the first study demonstrating that basophil count may be an associated factor for deceased BMD. Keywords: Postmenopausal women, Bone mineral density, Complete blood count, Basophil
