Plain language summary
Fragility fractures are associated with both personal and healthcare system burdens. It is well established that bone loss leading to osteopenia or osteoporosis results in increased risk of fractures. Prescription of pharmacological agents is commonly used as first-line treatment. The aim of this study was to evaluate the effect of the Osteo-cise: Strong Bones for Life program on the patient-reported outcomes including health related quality of life (HRQoL), osteoporosis knowledge and osteoporosis attitudes and beliefs. This study is a secondary analysis of an 18-month randomised controlled trial in which participants were randomly allocated to either the community-based Osteo-cise: Strong Bones for Life program (‘Osteo-cise’) or a standard care control group. Results showed that there were no significant effects on HRQoL, osteoporosis knowledge or osteoporosis attitudes and beliefs compared with usual care. However, per protocol analyses revealed that those most adherent to exercise training did experience significant improvements in both HRQoL and osteoporosis knowledge compared with usual care. Authors concluded that their findings highlight the need to identify strategies that promote long-term adherence to multifaceted exercise programs in community-dwelling older adults.
Abstract
UNLABELLED This study identified that an 18-month community-based, multifaceted, exercise program consisting of resistance, weight-bearing impact, and balance/mobility training combined with osteoporosis education and behavioural support can improve health-related quality of life (HRQoL) and osteoporosis knowledge in older adults at risk of fracture, but only for those adherent to the exercise regime. PURPOSE To evaluate the effects of an 18-month community-based exercise, osteoporosis education and behaviour change program (Osteo-cise: Strong Bones for Life) on HRQoL, osteoporosis knowledge and osteoporosis health beliefs. METHODS This was a secondary analysis of an 18-month randomised controlled trial in which 162 older adults aged ≥ 60 years with osteopenia or increased falls/fracture risk were randomized to the Osteo-cise program (n = 81) or control group (n = 81). The program consisted of progressive resistance, weight-bearing impact and balance training (3 days/week); osteoporosis education to facilitate self-management of musculoskeletal health and behavioural support to enhance adherence to exercise. HRQoL, osteoporosis knowledge and osteoporosis health beliefs were assessed using the EuroQoL questionnaire (EQ-5D-3L), Osteoporosis Knowledge Assessment Tool and Osteoporosis Health Belief Scale, respectively. RESULTS Overall, 148 participants (91%) completed the trial. Mean exercise adherence was 55% and mean attendance for the three osteoporosis educational sessions ranged from 63-82%. After 12 and 18 months, there were no significant effects of the Osteo-cise program on HRQoL, osteoporosis knowledge or health beliefs relative to controls. Per protocol analyses (≥ 66% exercise adherence; n = 41) revealed a significant net benefit in EQ-5D-3L utility for the Osteo-cise group relative to controls after 12 months (P = 0.024) and 18 months (P = 0.029) and a significant net improvement in osteoporosis knowledge scores at 18 months (P = 0.014). CONCLUSION This study supports the importance of adherence to exercise regimes, as adherence to the Osteo-cise: Strong Bones for Life program was associated with improvements in HRQoL and osteoporosis knowledge in older adults at increased risk for falls and fractures.

Osteoporosis (OP) is the most common metabolic bone disease associated with aging. Microbiome dysbiosis leading to impaired intestinal immune responses and subsequent production of osteoclastogenic cytokines has been proposed as the mechanism by which gut microbes are associated with osteoporosis. The aim of this study was to identify gut bacteria consistently associated with osteoporosis across different cohorts. This study was a meta-analysis of five studies. Results showed that gut microbial dysbiosis in osteoporosis patients is associated with functional changes, which result in significant changes in metabolites that play a key role in bone metabolism. Authors concluded that their findings set the stage for future studies to provide more comprehensive knowledge on how dysbiosis in the gut microbiome contributes to osteoporosis.
Abstract
Over the past decade, the role of the gut microbiota in many disease states has gained a great deal of attention. Mounting evidence from case-control and observational studies has linked changes in the gut microbiota to the pathophysiology of osteoporosis (OP). Nonetheless, the results of these studies contain discrepancies, leaving the literature without a consensus on osteoporosis-associated microbial signatures. Here, we conducted a comprehensive meta-analysis combining and reexamining five publicly available 16S rRNA partial sequence data sets to identify gut bacteria consistently associated with osteoporosis across different cohorts. After adjusting for the batch effect associated with technical variation and heterogeneity of studies, we observed a significant shift in the microbiota composition in the osteoporosis group. An increase in the relative abundance of opportunistic pathogens Clostridium sensu stricto, Bacteroides, and Intestinibacter was observed in the OP group. Moreover, short-chain-fatty-acid (SCFA) producers, including members of the genera Collinsella, Megasphaera, Agathobaculum, Mediterraneibacter, Clostridium XIV, and Dorea, were depleted in the OP group relative to the healthy control (HC) group. Lactic acid-producing bacteria, including Limosilactobacillus, were significantly increased in the OP group. The random forest algorithm further confirmed that these bacteria differentiate the two groups. Furthermore, functional prediction revealed depletion of the SCFA biosynthesis pathway (glycolysis, tricarboxylic acid [TCA] cycle, and Wood-Ljungdahl pathway) and amino acid biosynthesis pathway (methionine, histidine, and arginine) in the OP group relative to the HC group. This study uncovered OP-associated compositional and functional microbial alterations, providing robust insight into OP pathogenesis and aiding the possible development of a therapeutic intervention to manage the disease. IMPORTANCE Osteoporosis is the most common metabolic bone disease associated with aging. Mounting evidence has linked changes in the gut microbiota to the pathophysiology of osteoporosis. However, which microbes are associated with dysbiosis and their impact on bone density and inflammation remain largely unknown due to inconsistent results in the literature. Here, we present a meta-analysis with a standard workflow, robust statistical approaches, and machine learning algorithms to identify notable microbial compositional changes influencing osteoporosis.

Plain language summary
Osteoporosis is associated with severe complications, such as osteoporotic fracture and fracture-related functional disability. Risk factors for osteoporosis must be identified and validated at the earliest. The aim of this study was to investigate the association of coffee and tea intake with bone mass density (BMD) and hip fracture risk. This study was a systematic review and meta-analysis of 106 studies. In total, 416,847 individuals (BMD related studies, 99,750 individuals; hip fracture–related studies, 408,562 individuals) were included in the final analysis. Results showed that the daily intake of caffeinated beverages, such as coffee and tea, is not associated with BMD or hip fracture risk, particularly in postmenopausal women. Authors concluded that their findings help reduce the inconsistency in the current literature. Furthermore, it may serve as a reference for future studies aimed at identifying the risk factor for osteoporosis.
Abstract
Background and Objectives: Osteoporosis is characterized by low bone mass and high bone fragility. Findings regarding the association of coffee and tea intake with osteoporosis have been inconsistent. We conducted this meta-analysis to investigate whether coffee and tea intake is associated with low bone mineral density (BMD) and high hip fracture risk. Materials and Methods: PubMed, MEDLINE, and Embase were searched for relevant studies published before 2022. Studies on the effects of coffee/tea intake on hip fracture/BMD were included in our meta-analysis, whereas those focusing on specific disease groups and those with no relevant coffee/tea intake data were excluded. We assessed mean difference (MD; for BMD) and pooled hazard ratio (HR; for hip fracture) values with 95% confidence interval (CI) values. The cohort was divided into high- and low-intake groups considering the thresholds of 1 and 2 cups/day for tea and coffee, respectively. Results: Our meta-analysis included 20 studies comprising 508,312 individuals. The pooled MD was 0.020 for coffee (95% CI, -0.003 to 0.044) and 0.039 for tea (95% CI, -0.012 to 0.09), whereas the pooled HR was 1.008 for coffee (95% CI, 0.760 to 1.337) and 0.93 for tea (95% CI, 0.84 to 1.03). Conclusions: Our meta-analysis results suggest that daily coffee or tea consumption is not associated with BMD or hip fracture risk.

Plain language summary
Menopause is the permanent cessation of menstrual cycles following the loss of ovarian follicular activity. It is associated with increased prevalence of obesity, metabolic syndrome, cardiovascular disease, and osteoporosis. The aim of this narrative review was to discuss the current evidence on the association between dietary patterns and clinical endpoints in postmenopausal women (body composition, bone mass, and risk markers for cardiovascular disease), and thereby providing novel insight into the establishment of optimal dietary guidelines for healthy postmenopausal period. Research shows that: - the changes in weight and fat distribution in women are associated with aging and mainly with the decrease in oestradiol levels during peri- and post-menopause. - calcium, vitamin D, vitamin K, selenium, magnesium, and beta-carotene adequate intake could be linked with better BMD in postmenopausal women. - diet is a major modifiable risk factor for cardiovascular disease and could be a powerful intervention to reduce cardiovascular risks in postmenopausal women. - the Mediterranean diet is composed of healthy foods that have anti-inflammatory and antioxidant properties. Authors indicate that future studies evaluating the effects of low-fat, plant-based diets on fat mass in post-menopausal women are needed.
Abstract
Among the various aspects of health promotion and lifestyle adaptation to the postmenopausal period, nutritional habits are essential because they concern all women, can be modified, and impact both longevity and quality of life. In this narrative review, we discuss the current evidence on the association between dietary patterns and clinical endpoints in postmenopausal women, such as body composition, bone mass, and risk markers for cardiovascular disease. Current evidence suggests that low-fat, plant-based diets are associated with beneficial effects on body composition, but further studies are needed to confirm these results in postmenopausal women. The Mediterranean diet pattern along with other healthy habits may help the primary prevention of bone, metabolic, and cardiovascular diseases in the postmenopausal period. It consists on the use of healthy foods that have anti-inflammatory and antioxidant properties, and is associated with a small but significant decrease in blood pressure, reduction of fat mass, and improvement in cholesterol levels. These effects remain to be evaluated over a longer period of time, with the assessment of hard outcomes such as bone fractures, diabetes, and coronary ischemia.

Plain language summary
Osteoporosis is a disease where bone density is decreased and is often seen in postmenopausal women. Current prescribed treatments are costly and can often have serious side effects and as a result natural treatments are often requested. Probiotics have been shown in previous studies to be of benefit to bones, however no large review of all the available studies has been performed. This systematic review and meta-analysis of current randomised control trials (RCT’s) aimed to summarise the effect of probiotics on bone density in postmenopausal women. The results showed that only five RCT’s were available on the effect of probiotics on bone density of which there were 497 postmenopausal women. Bone density at the base of the spine was increased in women taking probiotics, however there was no difference seen in bone density of the hip. Bone markers for bone degradation were decreased, however other markers associated with bone density changes were unaffected. It was concluded that probiotics may increase bone density at the base of the spine, however more high-quality studies are needed. This study could be used by healthcare professionals to understand how probiotics may be of benefit to postmenopausal women, however definitive recommendations based on this study may need to be made with caution.
Abstract
OBJECTIVE Osteoporosis is a common disease in postmenopausal women. Several studies have analysed the associations between dietary supplementation with probiotics and bone health in postmenopausal women, but the results are still controversial. We conducted this meta-analysis to assess the effects of probiotics supplement on bone mineral density (BMD) and bone turnover markers for postmenopausal women. DESIGN Systematic review and meta-analysis. METHODS We systematically searched PubMed, EMBASE and the Cochrane Library from their inception to November 2020 for randomised controlled trials (RCTs) assessing probiotic supplements and osteoporosis in postmenopausal women. Study-specific risk estimates were combined using random-effect models. RESULTS Five RCTs (n=497) were included. Probiotic supplements were associated with a significantly higher BMD in the lumbar spine (standardised mean difference, SMD=0.27, 95% CI 0.09 to 0.44) than in control. There was no difference between probiotic supplements and BMD in hips (SMD=0.22, 95% CI -0.07 to 0.52). Collagen type 1 cross-linked C-telopeptide levels in the treatment groups were significantly lower than those of the placebo group (SMD=-0.34, 95% CI -0.60 to -0.09). In subgroup meta-analysis, levels of bone-specific alkaline phosphatase, osteoprotegerin, osteocalcin and tumour necrosis factor did not differ between the probiotic and placebo groups. CONCLUSIONS We conclude cautiously that supplementation with probiotics could increase lumbar BMD. More RCTs are recommended to validate or update these results.

Eating habits not only affect current health but may determine the development of future diseases in later stages of life. The appearance of genomics has presented an opportunity to explore the inter-individual differences in the metabolism of and response to nutrients. Nutraceuticals are biological substances extracted from natural sources by non-denaturing processes to preserve their original properties without any chemical manipulation. Thus, non-denaturation conditions and the use of the original matrix of the species allow all health-beneficial properties to remain intact. This review outlines that: - fish occupies the highest position in marine animal consumption. Literature shows strong links between fish and seafood consumption and positive health effects, particularly in a decreased risk of coronary heart and cardiovascular diseases, a decrease in inflammatory diseases such as arthritis, and the prevention of cancer. - the consumption of complex marine extracts provides numerous health benefits concerning the immune system, hypertension, atherosclerosis, arthritis, and menopause-related dysfunctions, and might reduce the risk of cardiovascular problems, osteoporosis, or senile muscle weakness. - based on nutrigenomic and epigenomic principles, nutritional advice can benefit the relationship between genes and the nutritional habit-related consequences. Authors conclude that the use of each person’s genetic profile for the prescription of nutraceuticals is a major goal to be striven for in order to improve their effectiveness in the prevention and natural treatment of prevalent diseases.
Abstract
The investigation of new alternatives for disease prevention through the application of findings from dietary and food biotechnology is an ongoing challenge for the scientific community. New nutritional trends and the need to meet social and health demands have inspired the concept of functional foods and nutraceuticals which, in addition to their overall nutritional value, present certain properties for the maintenance of health. However, these effects are not universal. Nutrigenetics describes how the genetic profile has an impact on the response of the body to bioactive food components by influencing their absorption, metabolism, and site of action. The EbioSea Program, for biomarine prospection, and the Blue Butterfly Program, for the screening of vegetable-derived bioproducts, have identified a new series of nutraceuticals, devoid of side effects at conventional doses, with genotype-dependent preventive and therapeutic activity. Nutrigenomics and nutrigenetics provide the opportunity to explore the inter-individual differences in the metabolism of and response to nutrients, achieving optimal results. This fact leads to the concept of personalized nutrition as opposed to public health nutrition. Consequently, the development and prescription of nutraceuticals according to the individual genetic profile is essential to improve their effectiveness in the prevention and natural treatment of prevalent diseases.

Plain language summary
The body composition of postmenopausal women changes rapidly due to hormonal changes, including the loss of bone (osteoporosis) and muscle (sarcopenia), usually in the presence of increased adiposity and fat redistribution towards central-type obesity. The aim of this study was to summarise the efficacy of soy foods and their impact on body composition. Research shows that soy products: - may improve the body composition of menopausal and premenopausal women. - delay the physical disabilities of menopausal women with osteosarcopenia and obesity. - may improve muscle mass and bone strength to prevent the development of osteosarcopenia in post-menopausal women. Authors conclude that further research is required since some studies have questioned the mechanism of the protective effect of soybean ingredients on certain metabolic diseases.
Abstract
Chronic diseases in postmenopausal women are caused by rapid changes in hormones and are accompanied by rapid changes in body composition (muscle, bone, and fat). In an aging society, the health of postmenopausal women is a social issue, and people's interest in ingesting high-quality protein is increasing in order to maintain a healthy body composition. This review aims to summarize the efficacy of soy foods and their impact on body composition. The soy protein and isoflavones contained in soy foods can improve muscle and bone density quality and reduce body weight. It is considered a breakthrough in preventing osteosarcopenia and obesity that may occur after menopause.

Coeliac disease (CD) is an autoimmune disorder and is known to be associated with a decrease in bone mineral density (BMD). Findings suggest 40-70% of patients with coeliac disease (CD) have low BMD, however this prevalence has been reported without considering confounding variables, such as age, menopause status, lifestyle factors and co-morbidities. The purpose of this review was to show the prevalence of osteoporosis and osteopenia in men and premenopausal women with coeliac disease (CD). This systematic review included 19 studies representing 563 subjects. Based on the current literature the pooled prevalence of osteoporosis was 14.4% and osteopenia was 39.6%. According to these results, the authors conclude bone loss is more prevalent in those with CD however larger case-controlled studies are required to adjust for confounding factors.
Abstract
BACKGROUND Celiac disease (CD) is known as a reason of metabolic osteopathy. Progression of non-invasive methods such as bone densitometry has shown that an important ratio of CD cases is faced with impaired bone mass and such cases are prone to bone fractures. Variety of low bone mineral density in CD is probably because of ignored confounding factors such as age, menopause, and drug. The aim of our study was to systematically review the osteoporosis and osteopenia incidences among premenopausal females and males with CD. METHODS This systematic review was done based on preferred reporting items for systematic reviews (PRISMA) guidelines. PubMed and Scopus and Cochran databases were searched according to the relevant medical subject headings (MeSH) of CD and bone mineral density until 2018. Prevalence of osteopenia and osteoporosis were used as effect size for meta-analysis. Cochrane Q (p < 0.05) and I2 index were presented to reveal the heterogeneity. RESULTS 54 eligible full text reviews were included and nineteen selected for data extraction. Eleven articles didn't have our inclusion criteria and had ignored confounding factors like age and menopause, and we excluded; data extraction was done in eight studies. A total of 563 premenopausal women and men who were from, UK, Brazil, India, Hungary, and Poland were included. The pooled prevalence of osteoporosis was 14.4% [95%CI: 9-20.5%] (Cochrane Q = 7.889, p = 0.96, I2 = 49.29%), and osteopenia was 39.6% [31.1-48.8%] (Cochrane Q = 14.24, p = 0.07, I2 = 71.92%), respectively. CONCLUSION Our findings suggest that bone loss is more prevalent in celiac disease and can be associated with increased risk of fracture. However, but results are pooled prevalence and we need more case -control studies with more sample size and consideration of confounding factors.
