The Utility of Radiomorphometric Mandibular Indices on Cone Beam Computer Tomography in the Assessment of Bone Mass in Postmenopausal Women: A Cross-Sectional Study.

The present study examined the potential use of computed tomography radiomorphometric mandibular indices on cone beam CT (CBCT) for the assessment of bone density in postmenopausal women with low bone mass. We included 104 postmenopausal women who received dual-energy X-ray absorptiometry (DXA) using a DXA scanner and mental foramen (MF) region CBCT using a NewTom VGi EVO Cone Beam 3D system. We assessed the relationships between the following DXA parameters: lumbar, femoral neck, and total hip T-scores, bone mineral density (BMD), lumbar trabecular bone score (TBS), and mandibular inferior cortical bone thickness at 4 sites. The cross-sectional images were obtained, as follows: anterior (A)-10 mm anterior from the MF; molar (M)-10 mm posterior from the MF; posterior (P)-25 mm posterior from the MF; symphysis (S)-equidistant from the centers of the right and left MF. We found that A and M indices showed statistically significant moderate positive correlations with lumbar spine, femoral neck, and total hip BMD, as well as TBS. The P index demonstrated moderate positive correlations with these measurements, while the S index did not show significant correlations with BMD or TBS in postmenopausal women. These findings support the potential usefulness of CBCT-derived radiomorphometric mandibular indices for non-invasive bone health assessment in clinical practice.

Effect of laparoscopic cholecystectomy on 25-hydroxyvitamin D levels and bone mineral density in post menopausal women

Background Laparoscopic cholecystectomy (LC) is the gold standard management for benign gallbladder diseases. It has been observed that there is alteration in vitamin D levels and bone mineral density after cholecystectomy due to altered enterohepatic circulation. With increase in average age expectancy of the population, low levels of vitamin D levels and osteoporosis after cholecystectomies might cause increased health care burden. Methods A prospective observational study was planned between 1 January 2022 and 30 June 2023 in the Department of General Surgery at PGIMER Chandigarh, a tertiary care hospital in north India. One hundred and three post-menopausal women who underwent LC and met the inclusion and exclusion criteria were included in the study. All participants underwent estimation of vitamin D and bone mineral density preoperatively and third-post operative month (POM). Results The mean age of the patients was 58.46 ± 7.44. Pain abdomen was present in 68(66%) patients, 18 had epigastric discomfort and 17 had dyspepsia. The mean levels of vitamin D decreased from 21.92 at the baseline to 20.12 at third POM (p < .001). There was a significant change in t score Femoral Neck (−1.12 vs −1.15, p < .001) and Lumbar spine L1–L4 − 1.98 vs −1.98 (p = .033). z-scores of the femoral neck were −0.34 vs −0.54 (p < .001) and of lumbar spine L1–L4 were −0.95 vs 1.02 (p < .001). The decrease in fracture risk for the femoral neck (p = .344) and the lumbar spine (p = .223) was not statistically significant. Conclusion There is a significant decrease in vitamin D and BMD levels after LC in post-menopausal females.

Benefits of Targeted Vibration for Bone Strength and Bone Density in Postmenopausal Women with Osteopenia: A Randomized, Sham-Controlled Trial

Abstract Postmenopausal women are at increased risk of fractures due to higher bone turnover that accompanies reduced estrogen production. Vibration may be an effective intervention for maintaining bone strength and bone density. The Osteoboost Belt is a wearable, home-use device that delivers targeted vibration to the lumbar spine and hips. This randomized, sham-controlled trial evaluated the safety and effectiveness of targeted vibration on bone strength and density in postmenopausal women with osteopenia. Participants (n = 126) were randomized (1:1) to receive the Active (vibration therapy device) or Sham (inactive device) treatment for 30 minutes/day over 12 months. At baseline and 12 months, computed tomography scans of the lumbar spine were analyzed to measure finite element analysis-assessed vertebral bone compressive strength (vertebral strength) and volumetric bone mineral density (vBMD) of the L1 vertebra. The primary endpoint, the difference in percentage change of vertebral strength between the Active (-1.40%, [95% CI: -2.73, -0.08]) and Sham (-2.74% [-4.04, -1.43]) groups in the modified intent-to-treat population, did not reach statistical significance (relative benefit: +1.33% [-0.57, 3.24], P=.17). However, a statistically significant benefit of targeted vibration was observed for participants who met the prespecified per-protocol compliance criterion (averaged ≥3 treatment sessions/week): -0.48% [-2.12, 1.17]) and -2.84% [-4.21, -1.47] (n = 73, P=.028) for Active and Sham groups, respectively. Similarly, in this compliant cohort, targeted vibration provided a statistically significant benefit on vertebral bone density, with the percentage change in vBMD of -0.29% [-1.28, 0.70] and -1.97% [-2.92, -1.01] (P=.016) for the Active and Sham groups, respectively. The vibration therapy was well-tolerated, and there were no serious device-related adverse events. These results demonstrate that targeted vibration is safe and, in adherent individuals, can significantly mitigate the decline in vertebral bone strength and vertebral bone density in postmenopausal women with osteopenia.

Bone density in postmenopausal women with scoliosis is associated with markers of degenerative joint disease.

Bone mineral density (BMD) measured with dual x-ray absorptiometry (DXA) is the clinical standard for the diagnosis of osteoporosis and prediction of bone fracture risk. In the aging skeleton, osteoporosis is often concomitantly present with degenerative joint disease (DJD). In this study, we evaluated tissue-level changes in the differentially loaded concave (CC) and convex (CV) sides of the lumbar spine in a sample of postmenopausal women with scoliosis. We used a cumulative degeneration score to assess osteophyte formation, the severity of sclerotic morphology, and marrow changes as markers of DJD in the lumbar spine and examined the correlation between markers of DJD and BMD. More severe osteophyte growth and sclerosis were present on the CC side of the spine. The degenerative score (DS) was higher on the CC side of the lumbar spine compared with the CV side. While CC BMD was positively correlated with CC DS and marrow, CV DS was not correlated with CV BMD. Marrow changes were correlated with DS on the CC lumbar spine. These results highlight the importance of mechanoadaptive as well as broader inflammatory processes in the manifestation of degenerative changes and local mineral deposition at the lumbar spine. DXA-based BMD measurement of osteoporosis need to be contextualized within the biomechanical and degenerative conditions of a joint rather than using a strict threshold cutoff.

How Bone Mineral Density Affect Periodontal Health in Postmenopausal Women using DEXA Scanning: A Digital Radiographic Study

Background: Periodontitis and osteoporosis are the diseases with common feature of both bone loss. However, the relation and extent between these diseases is still unclear. The purpose of present study was to evaluate the relationship between periodontal status and systemic bone mineral density in postmenopausal women. Methods and Material: A total of 40 postmenopausal women aged between 45–60 Years (50.6±4.6 years) were randomly selected from the department of periodontics. All women were examined for periodontal status and Bone Mineral Density(BMD). Periodontal status was examined by recording plaque index(PI), gingival index(GI), pocket probing depth(PPD), clinical attachment level (CAL) and alveolar bone loss (ABL). BMD was measured by Dual Energy X-ray absorptiometry (DEXA) scan for bone mineral density score. (T-score) values. The recorded data for T-score and periodontal status were subjected to statistical analysis for correlation and regression analysis. Results: The results showed that there was no statistically significant correlation between Probing depth (r= -0.168, P &gt; 0.05), gingival index (r= -0.441, P&gt;0.05), and plaque index (r= -0.345, P&gt;0.05) with T-score; whereas CAL (r= -0.604, P&gt;0.05) and ABL (r= -0.637, P&gt;0.05) was significantly correlated with T-score. Conclusion: In the present study systemic BMD was related to ABL and CAL, suggesting that postmenopausal bone loss can be a risk indicator for periodontal disease.

Effects of daily probiotic supplementation with Lactobacillus acidophilus on calcium status, bone metabolism biomarkers, and bone mineral density in postmenopausal women: a controlled and randomized clinical study.

Menopause poses significant health risks for women, particularly an increased vulnerability to fractures associated with osteoporosis. Dietary interventions have emerged as promising strategies, focusing on mitigating the risk of osteoporosis rather than solely addressing the established disease. This 12-week randomized controlled trial aimed to analyze the effects of consuming Lactobacillus acidophilus probiotics on calcium levels, biomarkers of bone metabolism, and bone mineral density (BMD) profiles in postmenopausal women. Fifty-five participants were randomly assigned to receive either a placebo (n = 25) or the probiotic L. acidophilus UALa-01™ (n = 30) daily via oral intervention. Throughout the study, evaluations included body composition, blood biochemical parameters, serum calcium levels, and biomarkers of bone metabolism. Additionally, Dual-energy X-ray absorptiometry was used to measure BMD profiles. The findings delineated that the probiotic group experienced a decrease in serum calcium levels compared to their initial levels. However, hair calcium levels and biomarkers related to bone metabolism showed no notable changes within this group. Consumption of probiotic L. acidophilus also seemed to prevent fluctuations in bone turnover markers. Moreover, there were no significant alterations in BMD levels at the lumbar spine, left femur, and total body in the probiotic group. Additionally, probiotic intake led to favorable outcomes by significantly reducing both body fat and visceral fat during the intervention period. Conversely, an adverse effect of consuming probiotic L. acidophilus was observed with a significant increase in glucose concentration. In conclusion, the consumption of L. acidophilus probiotics daily for 12 weeks among postmenopausal women does not affect the profile of BMD, but it may help in stabilizing bone turnover. It is important to note that most measured parameters were within the normal range for this population. However, it is worth noting that 3 months of probiotic supplementation could potentially disrupt calcium and glucose status in postmenopausal women.

Pan-immune inflammatory value a new diagnostic biomarker in postmenopausal osteoporosis

Aims: Postmenopausal osteoporosis (PMOP) is one of the most common bone diseases. We aimed to investigate the relationship between pan-immune inflammatory value and decreased bone mineral density in postmenopausal women. Methods: This prospective cross-sectional study was composed of 186 postmenopausal women. Osteoporosis was diagnosed with dual‐energy X‐ray absorptiometry (DEXA) results according to World Health Organization (WHO) recommendations and patients were separated into 3 groups; 1. control group with a T-score &gt;-1; 2. group osteopenia with a T-score between -1,0 and -2,5; 3. group osteoporosis with a T-score ≤-2,5. After the physical examinations of all patients, venous blood samples were collected and the pan-immune inflammation value (PIV) was calculated. The parameters were evaluated statistically with the PIV value between the groups. Results: Groups are similar in terms of age, menopausal age, education, and occupation. PIV was significantly higher in postmenopausal women with osteoporosis than women with osteopenia and the control group (p

Associations between the VDR Gene rs731236 (TaqI) Polymorphism and Bone Mineral Density in Postmenopausal Women from the RAC-OST-POL.

Postmenopausal osteoporosis is not only related to hormonal factors but is also associated with environmental and genetic factors. One of the latter is the polymorphism of vitamin D receptor (VDR). The aim of the reported study was to comprehensively analyze the VDR gene polymorphic variants rs731236 (TaqI), rs1544410 (BsmI) and rs7975232 (ApaI) in the Polish population of postmenopausal women. The study group consisted of 611 women after menopause (their median age was 65.82 ± 6.29 years). Each of them underwent bone densitometry (DXA) of the non-dominant femoral neck and total hip with a biochemical analysis of vitamin D3 serum concentration and genotyping of the above-mentioned single nucleotide polymorphisms (SNPs); the obtained results were analyzed in the aspect of waist circumference (WC), body mass index (BMI) and past medical history. The genotype prevalence rates of all SNPs were compatible with Hardy-Weinberg equilibrium (p > 0.050). Out of the studied polymorphisms, only rs731236 genotype variants affected DXA, with AG heterozygotes showing the worst bone parameters. Neither patient age nor vitamin D3 concentration, BMI, WC or comorbidities was associated with rs731236 genotype. Out of the polymorphisms studied, only rs731236 genotypes differed among the DXA results, while the AG heterozygotes were characterized by the lowest median bone mineral density.

Instrumental parameters of bone mineral density in postmenopausal women: combined use of ultrasound densitometry and the FRAX model

Osteoporosis is a systemic widespread disease of the musculoskeletal system that leads to impaired bone microarchitecture with a risk of fractures. The menopause period is one of the leading factors that leads to dysfunction of the RANK/RANKL/OTG signaling pathway, activating systemic inflammation. The purpose of the study was to determine the mineral status of bone tissue in menopausal women with simultaneous assessment of the risk of low-trauma fractures using ultrasound densitometry and the FRAX computerized model. The study included 153 people aged 20 to 89 years (mean age 55.3±15.4 years). Depending on the presence of menopause and gender, the corresponding groups were formed: I - main (menopausal women), II - control (women of reproductive age), III - comparison (men). The results of the study revealed a decrease in bone mineral density in the main group (I), where the T-criterion was -1.45± -1.95, compared with the control group (II) and comparison group (III), where the index was -0.51±0.7 and 0.27±0.72, respectively. The 10-year risk of any osteoporotic fractures according to the FRAX model demonstrates significantly higher risks in group I ([7.4 [4.0-15.0] %) compared to groups II and III, where the risks were 2.7 [2.4 - 3.3] % and 3.2 [2.3 - 3.8] %, respectively, p&lt; 0.0001. As a result of the combined use of ultrasound densitometry and the FRAX model, lower bone mineral density of the radial bones in the main group was found compared to the control and comparison groups. The above results indicate that hypoestrogenism caused by the onset of menopause is a key factor in the development of osteodysmetabolic syndrome.

Evaluation of Bone Density Changes Before and After One Year of Denosumab (Prolia) Administration in Osteoporosis Patients

Background: Osteoporosis, a widespread disease associated with aging, is characterized by a decrease in bone tissue density. With the global population aging, numerous studies aim to present methods for preventing or treating this disease to avoid pathological fractures by preserving bone density. Objectives: This study aimed to compare the changes in bone density in females with osteoporosis before and after receiving denosumab for at least one year. Methods: This clinical trial was conducted on 202 patients with osteoporosis who were referred to two private clinics in Tehran between 2019 and 2020. Each patient received two subcutaneous injections of 60 mg denosumab (Prolia) once every six months. Bone density was measured using the DXA method, and the T-score and the risk of bone fracture were calculated and compared using the FRAX instrument before drug administration and six months after the second dose injection. Results: The average age of the participants was 69.0 ± 8.0 years. Significant differences were observed in vertebral bone density (-2.55 ± 0.06 to -2.00 ± 0.07) and femur bone density (-2.10 ± 0.10 to -1.88 ± 0.06) before and after denosumab treatment (P &lt; 0.05). Furthermore, the risk of major fractures (23.0 ± 1.9 to 18.9 ± 1.5) and hip fractures (8.5 ± 1.3 to 5.7 ± 0.9) significantly decreased before and after treatment with denosumab (P &lt; 0.05). A significant improvement in bone density was observed across all age groups of patients before and after treatment with denosumab (P &lt; 0.05). Conclusions: Denosumab significantly reduces the risk of bone fractures and enhances bone density in postmenopausal women. It proves to be an effective medication for reducing the increased risk of fractures in postmenopausal women and for improving their bone density.

Association of neutrophil to lymphocyte ratio with bone mineral density in post-menopausal women: a systematic review and meta-analysis

BackgroundWe conducted a systematic review and meta-analysis to compare the neutrophil lymphocyte ratio (NLR) levels between women with post-menopausal osteopenia or osteoporosis to those with normal bone mineral density (BMD).MethodsWe used Web of Science, PubMed, and Scopus to conduct a systematic search for relevant publications published before June 19, 2022, only in English language. We reported standardized mean difference (SMD) with a 95% confidence interval (CI). Because a significant level of heterogeneity was found, we used the random-effects model to calculate pooled effects. We used the Newcastle–Ottawa scale for quality assessment.ResultsOverall, eight articles were included in the analysis. Post-menopausal women with osteoporosis had elevated levels of NLR compared to those without osteoporosis (SMD = 1.03, 95% CI = 0.18 to 1.88, p = 0.017, I2 = 98%). In addition, there was no difference between post-menopausal women with osteopenia and those without osteopenia in neutrophil lymphocyte ratio (NLR) levels (SMD = 0.58, 95% CI=-0.08 to 1.25, p = 0.085, I2 = 96.8%). However, there was no difference between post-menopausal women with osteoporosis and those with osteopenia in NLR levels (SMD = 0.75, 95% CI=-0.01 to 1.51, p = 0.05, I2 = 97.5%, random-effect model).ConclusionThe results of this study point to NLR as a potential biomarker that may be easily introduced into clinical settings to help predict and prevent post-menopausal osteoporosis.

Cigarette smoking and mammographic breast density in post-menopausal women from the EPIC Florence cohort.

Cigarette smoking has been recognized as a risk factor for breast cancer (BC) also if the biological mechanism remains poorly understood. High mammographic breast density (MBD) is associated with BC risk and many BC risk factors, such as genetic, anthropometric, reproductive and lifestyle factors and age, are also able to modulate MBD. The aim of the present study was to prospectively explore, in post-menopausal women, the association between smoking habits and MBD, assessed using an automated software, considering duration and intensity of smoking. The analysis was carried out in 3,774 women enrolled in the European Prospective Investigation into Cancer and Nutrition (EPIC) Florence cohort in 1993-98, participating in the 2004-06 follow up (FU) and with at least one full-field digital mammography (FFDM) performed after FU. For each woman, detailed information on smoking habits, anthropometry, lifestyle and reproductive history was collected at enrollment and at FU. Smoking information at baseline and at FU was integrated. The fully automated Volpara™ software was used to obtain total breast volume (cm3), absolute breast dense volume (DV, cm3) and volumetric percent density (VPD, %) from the first available FFDM (average 5.3 years from FU). Multivariable linear regression models were applied to evaluate the associations between smoking habits and VPD or DV. An inverse association between smoking exposure and VPD emerged (Diff% -7.96%, p <0.0001 for current smokers and -3.92%, p 0.01 for former smokers, compared with non-smokers). An inverse dose-response relationship with number of cigarettes/day, years of smoking duration and lifetime smoking exposure (pack-years) and a direct association with time since smoking cessation among former smokers emerged. Similar associations, with an attenuated effect, emerged when DV was considered as the outcome variable. This longitudinal study confirms the inverse association between active smoking, a known risk factor for BC, and MBD among post-menopausal women. The inclusion of smoking habits in the existing BC risk prediction models could be evaluated in future studies.

Effect of traditional Chinese fitness exercises on bone mineral density in postmenopausal women: a network meta-analysis of randomized controlled trials.

This study strictly followed the evaluation guidelines of PRISMA and followed the "PICOS" principle outlined in the Cochrane Handbook. We performed a systematic search on Web of Science, Springer Link, Scopus, EMBASE, EBSCO, PubMed, the Cochrane Library, CNKI, Wanfang, CBMdisc, and the VIP Database, and we targeted RCTs studying the effect of TCE on BMD in postmenopausal women published prior to September 2023. The quality of the literature and the risk of bias of the included studies were assessed according to ROB2 and GRADE criteria, and data analysis was performed using Stata 14. A total of 33 RCTs (3658 post-menopausal women) were included. Network meta-analysis showed that Taiji (SMD=0.72, 95% CI: 0.22, 1.21, P<0.01) and Yijinjing (SMD=0.51, 95% CI: 0.03, 0.99, P<0.05) were significantly superior to conventional rehabilitation in lumbar BMD. In terms of improvement of femoral neck BMD, Baduanjin (SMD=1.63, 95% CI: -3.58, 6.85, P<0.001) and Taiji (SMD=0.46, 95% CI: 0.14, 0.79, P<0.05) had statistically different outcomes to conventional rehabilitation. Regarding Ward's triangle BMD, Taiji (SMD= 0.32, 95% CI: 0.14, 0.50, P< 0.05) had statistically different outcomes to conventional rehabilitation. The results of the SUCRA probability ranking showed that Baduanjin + drug interventions achieved the most significant improvement in lumbar BMD (SUCRA=83.6%) and femoral neck BMD (SUCRA=90.2%). Taiji + drug interventions most effectively improved Ward's triangle BMD (SUCRA=86.0%). In terms of traditional Chinese fitness exercises alone, Taiji was the most effective in improving lumbar BMD (SUCRA=64.4%) and Ward's triangle BMD (SUCRA=46.8%), and Baduanjin was the most effective in treating femoral neck BMD (SUCRA=89.9%). Traditional Chinese fitness exercises can significantly improve the BMD levels of postmenopausal women. Taiji, Yijinjing, and Baduanjin combined with medication showed better intervention effects overall. However, due to the limitations of the number of studies and sample sizes of individual interventions, definitive conclusions need to be verified by more high-quality studies.

The impact of thyroid function on total spine bone mineral density in postmenopausal women.

Osteoporosis has been a widespread concern for older women, especially postmenopausal women. Thyroid function is crucial for bone metabolism. However, the relationship between thyroid function variation within thyroxine reference range and bone mineral density (BMD) remains ambiguous. The objective of this study was to evaluate the effect of subclinical hypothyroidism or hyperthyroidism on total spinal BMD in postmenopausal women. Based on data from the National Health and Nutrition Examination Survey (NHANES) 2007-2010, multivariable weighted logistic regression was used to evaluate the relationships between total spine BMD and TSH among postmenopausal women aged ≥50. After accounting for a number of variables, this study discovered that the middle TSH tertile was associated with a decreased probability of osteoporosis. Additionally, the subgroup analysis revealed that postmenopausal women over the age of 65 or people with an overweight BMI had a clearer relationship between total spine BMD and TSH. The total spinal BMD had a positive relationship with thyroid stimulating hormone in postmenopausal women, and that appropriate TSH level (1.38-2.32 mIU/L) was accompanied by higher total spinal BMD.

Unveiling the Burden of Osteoporosis: Exploring the Prevalence and Risk Factors among Postmenopausal Women in North Central Bangladesh.

Background: Osteoporosis affects 30% of women globally between the ages of 40 and 50. This disease is among the top causes of death and disability among the elderly. This study aimed to examine the prevalence of primary osteoporosis and poor bone density in postmenopausal women, as well as their socio demographic, obstetric, and lifestyle risk factors. Aim: The purpose of this study is to investigate at the prevalence of osteoporosis and the risk factors linked with it in postmenopausal women. Methods: The present prospective cross-sectional study was conducted on postmenopausal women who visited orthopedics, gynecology, and medicine outpatient departments between August 2022 and March 2023; 539 women aged 45 to 80 years with verified menopause were recruited. The final recommendation was for 539 women to have bone mineral density testing utilizing dual energy X-ray absorptiometry. Socio-individual, obstetric-medical, short-form physical activity, and anthropometric questionnaires were administered. Chi-square and Student's t-tests were applied to categorical and continuous data, respectively, to assess the differences between the groups. In SPSS 26, P&lt;0.05 was regarded to indicate significant connections. Results: In our study, 38.0% of participants were between56 and 60 years of age. The majority of the individuals (51.9%) were illiterate. 37.7% of respondents reported having six or more children. 3.6% of the sample smoked or chewed tobacco. 61.0 percent of individuals had menopause after the age of 45, and 48.8% of subjects had experienced menopause for more than ten years at the time of enrollment in the research. 83.5% of postmenopausal women were affected by osteoporotic fractures (osteoporosis: 40.0% and osteopenia: 43.5%). The incidence of osteoporosis rose as parity and abortion rates increased. The prevalence of osteoporosis was greater (P&lt; 0.05) among those with a familial history of osteoporosis-related symptoms and fragility fracture, as well as a personal history of fragility fracture. Conclusion: Given the significant prevalence of primary osteoporosis and poor bone density in postmenopausal women, health education is essential for minimizing modifiable risk factors and mitigating the disease's consequences.

Associations of healthy eating index-2015 with osteoporosis and low bone mass density in postmenopausal women: a population-based study from NHANES 2007-2018.

The current study aimed to explore the associations of diet quality assessed by healthy eating index-2015 (HEI-2015) with risks of osteoporosis and low bone mineral density (BMD) among American postmenopausal women aged 50 years and older. Postmenopausal women aged 50 years and older in the National Health and Nutrition Examination Survey from 2007 through 2018 were included in the final sample. Analysis of variance and Rao-Scott adjusted chi-square tests were used to compare the characteristics across tertiles of HEI-2015. Univariate and multivariate weighted logistic regression models were employed to explore the associations of HEI-2015 tertiles and continuous HEI-2015 with the risks of osteoporosis and low BMD. Nonlinear dose-response associations were evaluated using weighted restricted cubic spline analyses, and the contributions of various HEI-2015 components were assessed using weighted quantile sum regression models. The final sample included 3,421 postmenopausal women aged 50 years and older representative for approximately 28.38 million non-institutionalized U.S. postmenopausal women. Osteoporosis prevalence decreased with HEI-2015 tertiles while the prevalence of low BMD showed no significant decrease. Compared with postmenopausal women in the first tertile of HEI-2015, those with the second (OR: 0.57, 95%CI: 0.38-0.84) and third (OR: 0.48, 95%CI: 0.29-0.78) HEI-2015 tertiles were associated with reduced osteoporosis risk after multivariate adjustments, but no significant association of HEI-2015 with the risk of BMD was identified. Furthermore, similar effects were confirmed in the sensitivity analyses and subgroup analyses and interaction effects. Moreover, significant nonlinear associations were observed between HEI-2015 with osteoporosis risk, and total vegetables, refined grains and greens and beans demonstrated the strongest protective effect among HEI-2015 components against osteoporosis. This study strongly suggests the significant negative associations of HEI-2015 with osteoporosis risk in American postmenopausal women. These findings highlight the importance of adherence to the dietary guidelines for Americans in reducing the risk of osteoporosis.
