The Relationship between Bone Health Parameters, Vitamin D and Iron Status, and Dietary Calcium Intake in Young Males. Nutrients 2024; 16:215. [PMID: 38257108 PMCID: PMC10818825 DOI: 10.3390/nu16020215] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 12/29/2023] [Accepted: 01/02/2024] [Indexed: 01/24/2024] Open
Abstract
Vitamin D, calcium, and iron are micronutrients crucial for bone health. However, their effect has been studied primarily in the cortical bone, with vitamin D status being assessed mainly from the total 25(OH)D serum fraction. The study aimed to investigate the impact of vitamin D (total and free fraction) and iron status (i.e., serum ferritin or soluble transferrin receptor) and calcium intake (ADOS-Ca questionnaire) on lumbar cortical and trabecular bone. In a cohort of 113 male subjects (76 athletes, 37 non-athletes) aged 15-19, the lumbar spine status (Z-score, bone mineral apparent density (BMAD), and trabecular bone score (TBS)) was determined using dual-energy X-ray absorptiometry (DXA). Relationships between the examined micronutrients and bone health parameters were observed only in athletes. Free 25(OH)D was significantly (p < 0.001) correlated with Z-score and BMAD, while total 25(OH)D (p < 0.001) and iron status (ferritin, Fe stores; p < 0.01) correlated solely with BMAD. Free 25(OH)D and ferritin concentrations were the best determinants of bone status (R2 = 0.330; p < 0.001) and explained 25% and 7% of the BMAD variance, respectively. No relationships were found between the micronutrients and TBS. The results confirmed the positive influence of vitamin D and iron on cortical, but not trabecular, bone status solely in physically active subjects. In athletes, free 25(OH)D seems to be a superior indicator of bone health to a total 25(OH)D fraction.

A Pilot, Open-Label, Proof-of-Concept Study To Evaluate the Efficacy and Safety of Asthiposhak® Tablets in Participants Suffering From Asthikshaya or Osteopenia. Cureus 2023; 15:e41862. [PMID: 37581133 PMCID: PMC10423404 DOI: 10.7759/cureus.41862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/14/2023] [Indexed: 08/16/2023] Open
Abstract
Introduction Both osteoporosis and osteopenia are prevalent public health concerns worldwide and can lead to debilitating bone fractures. This study aimed to assess the efficacy of Asthiposhak® Tablets in individuals with Asthikshaya (osteopenia) by measuring changes in the bone mineral density (BMD) score before and after the intervention, specifically between visit 1 (baseline) and visit 8 (after 180 days of treatment). Methods The single-arm study involved the screening of participants for Asthikshaya (osteopenia) using baseline investigations, which included a bone mineral density (BMD) assessment through a dual-energy X-ray absorptiometry (DEXA) scan. A total of 36 participants were enrolled in the study, who took two Asthiposhak Tablets three times a day with lukewarm water, for a period of 180 days. Safety assessments, along with evaluations of BMD (DEXA Scan), Ayurvedic Symptom Score, and serum biochemical markers, were conducted through blood investigations. Efficacy and safety data were analyzed using 'intention-to-treat' analysis. Descriptive statistics were used to express data in percentages, mean ± SD, or median (IQR). Data at different intervals were compared using paired t-tests or Wilcoxon signed-rank tests. One-way analysis of variance (ANOVA) with Bonferroni correction tested the significance between visits for the Ayurvedic Symptom Score, and Friedman's two-way analysis of variance by ranks measured differences in vital parameters. The significance level used was p<0.05. Results Out of the initially recruited 36 participants, 30 successfully completed the study, consisting of 12 males and 18 females, with an age range of 40 to 70 years and a mean age of 51.33 years. After 180 days of treatment with Asthiposhak Tablets, a statistically significant (p<0.05) improvement in hip and spine BMD (T-score) was observed. Additionally, significant reductions in the mean Total Ayurvedic Symptom Score were noted at both 90 and 180 days of treatment compared to day 0. Moreover, the levels of bone-specific alkaline phosphatase and osteocalcin, serum bone markers, showed statistically significant (p<0.05) reduction after 180 days of treatment compared to day 0. Importantly, all safety variables, including laboratory investigations, remained within the normal range following the 180-day treatment with Asthiposhak Tablets. Conclusion Asthiposhak Tablets exhibited significant efficacy in enhancing both BMD (T-score) and Ayurvedic Symptom Score, thereby substantiating their osteoprotective potential in individuals with Asthikshaya (osteopenia). Furthermore, the tablets were found to reduce the levels of biochemical markers, such as serum bone-specific alkaline phosphatase and osteocalcin, suggesting their anti-resorptive action.

Abstract
Whole-body vibration therapy is an intentional biomechanical stimulation of the body using various frequencies of vibrations with the motive of health improvement. Ever since its discovery, this therapy has been extensively used in physiotherapeutic measures and the sports industry. For its property of increasing bone mass and density, space agencies use this therapy on astronauts who return to Earth after long-term space missions to regain lost bone and muscle mass. The potential of this therapy to restore bone mass encouraged researchers to look for its scope in the treatment of age-related bone degenerative diseases such as osteoporosis and sarcopenia, as well as in the correction of posture control and gait in geriatrics and post-menopausal women. Osteoporosis and osteopenia account for roughly half of all fractures worldwide. These degenerative diseases also cause gait and posture changes. Bisphosphonates, monoclonal antibodies, parathyroid hormone fragments, hormone replacement therapies, and calcium and vitamin D supplementation are among the medical treatments available. Lifestyle changes and physical exercise are advised. However, vibration therapy's scope as a treatment option is yet to be explored. The safe range of frequency, amplitude, duration, and intensity of the therapy is still to be determined. This article is a review of the results of various clinical trials done in the last 10 years that target the effect of vibration therapy in both osteoporotic women and the elderly for the treatment of such ailments and deformities. We collected data from PubMed using advanced search and applied the exclusion criteria. In total, we analyzed nine clinical trials.

OSTA as a screening tool to predict osteoporosis in Indian postmenopausal women - a nationwide study. Arch Osteoporos 2022; 17:121. [PMID: 36087221 DOI: 10.1007/s11657-022-01159-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Accepted: 08/22/2022] [Indexed: 02/03/2023]
Abstract
This cross-sectional study done on 5356 postmenopausal women showed that OSTA may be used as a reliable screening tool for osteoporosis across different regions of India, a country known for its ethno-linguistic, cultural, and genetic diversity. BACKGROUND The gold standard for diagnosing osteoporosis is DXA (dual-energy X-ray absorptiometry) scan, and this is not widely available across India. OSTA (Osteoporosis Self-Assessment Tool for Asians) score predicts risk of osteoporosis and can be used as reference tool for DXA. At a cutoff of ≤ + 1, OSTA predicted femoral neck osteoporosis with a sensitivity of 88% in a previous study among south Indian postmenopausal women. This study was done to validate the OSTA score in postmenopausal women across India. METHODOLOGY A cross-sectional study in 5356 postmenopausal women from four regions of India namely south, east, north, and west. Bone mineral density (BMD) and trabecular bone score (TBS) were assessed by DXA. The performance of OSTA in predicting BMD and TBS was assessed using ROC curve. RESULTS The mean (SD) age was 61.6 (7.6) years. The performance of OSTA in predicting osteoporosis was fair (P < 0.001) with an AUC of 0.727 (95% CI 0.705-0.749) in the south, 0.693 (95% CI 0.664-0.723) in east India, 0.730 (95% CI 0.700-0.759) in the north, and 0.703 (95% CI 0.672-0.735) in the western region. At a cut-off below + 1.0, sensitivity was 76-84% and specificity was 45-53% in diagnosing osteoporosis at any site. In predicting degraded microarchitecture, the AUC was 0.500-0.600. CONCLUSION OSTA may be reliably used as a screening tool for women at high risk of osteoporosis across India and may circumvent the limited availability of DXA scanners across the country.

Abstract
Background This is an observational study conducted to determine the prevalence of osteoporosis and osteopenia in patients undergoing elective arthroplasty and spinal procedures in India. Methods This observational, multicentre study included both male and female patients. Their bone mineral density and fracture risk were measured using dual-energy x-ray absorptiometry (DEXA) and Fracture Risk Assessment Tool (FRAX®: Centre for Metabolic Bone Diseases, University of Sheffield, UK), respectively, in compliance with the guidelines for Good Epidemiological Practice (ISRCTN: 14543098). Results The study revealed that majority (76.4%; 97/127) of the patients had low BMD; over one-third had osteoporosis (39.4%; 50/127) or osteopenia (37%; 47/127). Among those undergoing total knee replacement (TKR)/total hip replacement (THR), majority (75.6%; 59/78) had low BMD (osteoporosis: 38.5% {30/78}; osteopenia: 37.2% {29/78}). Among the patients undergoing spinal procedures, all except two (93.10%; 27/29) had low BMD, two-thirds had osteoporosis (65.5%; 19/29), and around one-fourth had osteopenia (27.6%; 8/29). Radial BMD measurements showed higher prevalence of osteoporosis and osteopenia. Based on FRAX score, nearly 30% of patients were at a high risk of hip fracture in the next 10 years. As per National Osteoporosis Foundation (NOF) guidelines, most (59.79%; 58/97) patients with osteoporosis/osteopenia met criteria for pharmacological treatment. Conclusions Regular preoperative bone health evaluation should be adopted and osteoporosis/osteopenia patients should be adequately managed pharmacologically in India.

Abstract
Dietary calcium deficiency is considered to be widespread globally, with published estimates suggesting that approximately half of the world's population has inadequate access to dietary calcium. Calcium is essential for bone health, but inadequate intakes have also been linked to other health outcomes, including pregnancy complications, cancers, and cardiovascular disease. Populations in low- and middle-income countries (LMICs) are at greatest risk of low calcium intakes, although many individuals in high-income countries (HICs) also do not meet recommendations. Paradoxically, many LMICs with lower calcium intakes show lower rates of osteoporotic fracture as compared with HICs, though data are sparse. Calcium intake recommendations vary across agencies and may need to be customized based on other dietary factors, health-related behaviors, or the risk of calcium-related health outcomes. The lack of standard methods to assess the calcium status of an individual or population has challenged efforts to estimate the prevalence of calcium deficiency and the global burden of related adverse health consequences. This paper aims to consolidate available evidence related to the global prevalence of inadequate calcium intakes and associated health outcomes, with the goal of providing a foundation for developing policies and population-level interventions to safely improve calcium intake and status where necessary.

Abstract
Objective: The primary purpose was to compare the effect of 2 mg and 4 mg of intravenous zoledronic acid (ZA) on change in the lumbar spine (LS) bone mineral density (BMD) at the end of 1 year in postmenopausal women with osteoporosis. The secondary objectives were changes in BMD at the total hip and femoral neck, change in bone turnover markers (BTMs), and the incidence of new fractures. Methods: This was a double-blind, parallel-arm, randomized control trial with an allocation ratio of 1:1 done in 70 postmenopausal women with osteoporosis. Findings: The mean (±standard deviation) percentage increase in LS BMD at the end of 1 year was 4.86% ± 3.05% and 5.35% ± 3.73% in the 2 mg and 4 mg group, respectively. The dose of 2 mg ZA proved to be inferior to 4 mg with a noninferiority margin of 0.5%. There was no difference in BMD change at hip and BTMs between the two groups at the end of 1 year. Only one patient in 4 mg group developed two new vertebral fractures during a 12-month follow-up. Acute-phase reactions were the most common (43%) side-effects noted without any difference between the two groups (P = 0.63). Conclusion: This study failed to show the noninferiority of 2 mg ZA compared to 4 mg ZA for change in LS BMD at the end of 1 year.

Abstract
UNLABELLED The Indian Society for Bone and Mineral Research (ISBMR) has herein drafted clinical practice guidelines for the diagnosis and management of osteoporosis for the people of India. Implementation of the position statement in clinical practice is expected to improve the overall care of patients with osteoporosis in India. PURPOSE In India, osteoporosis is a major public health problem. However, in the absence of any robust regional guidelines, the screening, treatment, and follow-up of patients with osteoporosis are lagging behind in the country. METHODS The Indian Society for Bone and Mineral Research (ISBMR), which is a multidisciplinary group of physicians, researchers, dietitians, and epidemiologists and who study bone and related tissues, in their annual meeting, drafted the guidelines for the diagnosis and management of osteoporosis that would be appropriate in a resource constraint setting like India. RESULTS Diagnosis of osteoporosis can be made in a patient with minimal trauma fracture without the aid of any other diagnostic tools. In others, bone mineral density measured by dual-energy X-ray absorptiometry remains the modality of choice. Data indicates that osteoporotic fractures occur at an earlier age in Indians than in the West; hence, screening for osteoporosis should begin at an earlier age. FRAX can be used for fracture risk estimation; however, it may underestimate the risk of future fractures in our population and still needs validation. Maintaining optimum serum 25-hydroxyvitamin D levels is essential, which, in most cases, would require regular vitamin D supplementation. Pharmacotherapy should be guided by the presence/absence of vertebral/hip fractures or the severity of risk based on clinical factors, although bisphosphonates remain the first choice in most cases. Regular follow-up is essential to ensure adherence and response to therapy. CONCLUSIONS Implementation of the position statement in clinical practice is expected to improve the overall care of patients with osteoporosis in India.

Abstract
UNLABELLED Osteoporosis is a disease with a high burden of morbidity. For its accurate diagnosis, using indigenous data as reference standards is needed. However, normative data on bone density is lacking in India. Therefore, we aimed to determine the reference range for bone density for the healthy population of north India. INTRODUCTION Osteoporosis is a major public health problem around the globe including India, resulting in significant morbidity, mortality, and health care burden. However, the reference values used for its diagnosis are largely based on data from the western population, which may lead to over- or underdiagnosis of osteoporosis in Indians. Our study aimed to determine the reference range for bone mineral density for the healthy population of India. METHODS This is a cross-sectional study of 825 subjects (men 380, women 445) (median age: 41 years, IQR 32-55 years), recruited by a house-to-house survey. The population was stratified into decade-wise groups and biochemical measurements including renal and liver function tests, glycated hemoglobin, serum calcium, 25-hydroxyvitamin D, parathyroid hormone, and bone mineral density were performed in all the subjects. The T-scores for men aged > 50 years and post-menopausal women were calculated based on the data generated from this study in young men and women aged 20-40 years. RESULTS According to the BMD manufacturer's data, which is based on the western population, 70% of the Indian men (> 50 years) and 48% of the post-menopausal Indian women had osteopenia while 18% of the men and 25% of the women had osteoporosis. However, according to the re-calculated T-scores from the current study, only 56% and 7.2% of men and 33% and 5% of women had osteopenia and osteoporosis, respectively. An age-related decline in bone mineral density, as seen in the western population, was also seen in both Indian men and women. CONCLUSION We have established a reference database for BMD in healthy Indian adult population, which may have clinical implications for the diagnosis and intervention strategies for the management of osteoporosis.

Bone alkaline phosphatase and urine hydroxyproline assay in pre and postmenopausal women in the state of sikkim and its correlation with bone mineral density. J Midlife Health 2021; 12:304-309. [PMID: 35264838 PMCID: PMC8849151 DOI: 10.4103/jmh.jmh_73_21] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 09/11/2021] [Accepted: 12/07/2021] [Indexed: 11/04/2022] Open
Abstract
Introduction: Osteoporosis could be viewed as a metabolic disease. The WHO guidelines for diagnosing osteoporosis reflect structural damage only and not the metabolic imbalance that leads to it. Biochemical markers of bone turnover have been shown to provide valuable information for diagnosing and monitoring metabolic bone disease. The present study analyzed bone-specific alkaline phosphatase (BALP) and urinary hydroxyproline in pre- and postmenopausal women and correlated them with changes in bone mineral density (BMD) in the state of Sikkim. The study also intended to know the ethnicity-based disease burden in Sikkim. Materials and Methods: A hospital-based cross-sectional study was done at a tertiary hospital in Sikkim. Blood and 24-h urine samples from 50 premenopausal and 50 postmenopausal women were analyzed for total alkaline phosphatase (ALP), BALP, and Urine Hydroxyproline. BMD was measured using the quantitative ultrasound technique by Achilles densitometer. Results: There was a statistically significant increase in serum calcium (P = 0.01), ALP (P = 0.01), and urine hydroxyproline (P = 0.03) levels in postmenopausal women as compared to premenopausal women. Although ALP was higher in postmenopausal women, BALP isoform was more elevated in premenopausal women (P = 0.001). BMD was significantly lower in postmenopausal women (P < 0.001). It was also noted that there was a significant difference in BMD between tribal and nontribal populations (P = 0.003). Total ALP and BALP as the bone formation marker and urine hydroxyproline as a bone resorption marker added statistically significant r to BMD prediction (P < 0.05). Conclusion: In this study, BALP combined with Urine Hydroxyproline was helpful as a screening biomarker to predict osteoporosis in postmenopausal women.

Assessment of Bone Quality Using Radiogrammetric Parameters of Proximal Humerus in India: Defining the Osteoporotic Fracture Risk Limit Value and its Reliability. Indian J Orthop 2020; 54:307-315. [PMID: 33194106 PMCID: PMC7609647 DOI: 10.1007/s43465-020-00224-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Accepted: 08/03/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND World health organization (WHO) has defined osteoporosis clinically on the basis of bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) scan and the presence of fractures. This facility is expensive and not readily available in majority of the centers in India. The authors have attempted to study defined measurements on radiographs (radiogrammetric parameters) to diagnose osteoporosis in Indian population. PATIENTS AND METHODS We prospectively studied 200 proximal humerus radiographs for measuring radiogrammetric parameters and divided into Group A and B (N = 100 in each group). Group A involved patients with age < 50 years and without any illness affecting bone quality. Group B involved patients with age > 50 years and sustained acute osteoporotic fractures of distal radius/ anterior wedge vertebral fracture/intertrochanteric fracture following trivial trauma. Three parameters (cortical thickness, cortical index and deltoid tuberosity index) were measured by 3 observers at 2 different occasions. RESULTS The mean age of patients was 37.87 years and 58.38 years for group A and B, respectively. The 'cortical thickness' of the proximal humerus diaphysis had the mean value for Group A and B to be 0.4 ± 0.07 cm and 0.33 ± 0.06 cm respectively. The mean values for the 'cortical index' of proximal humerus came out to be 0.4 ± 0.07 for group A and 0.32 ± 0.06 for group B. The 'deltoid tuberosity index' measurements showed the mean values for group A and B were 1.81 ± 0.23 and 1.55 ± 0.16, respectively. Inter-observer reliability for single measures was excellent for deltoid tuberosity index (ICC 0.8077) and good for cortical thickness (ICC 0.7032) and cortical index (ICC 0.7357). Observer 1 had excellent intra-observer reliabilities for all the three parameters. Observer 2 and 3 had excellent reliability for deltoid tuberosity index and good intra-observer reliability for cortical thickness and cortical index. The cortical thickness had a cut off of ≤ 0.372 cm with a sensitivity of 86.02 and specificity of 82.12. The cortical index had a cut off of ≤ 0.378 with a sensitivity of 89.16 and specificity of 84.22. The deltoid tuberosity index had a cut off of ≤ 1.684 with a sensitivity of 96.61 and specificity of 84.08. CONCLUSION The outcome of this study is likely to help in early diagnosis of osteoporosis at the community level in the absence of DXA scan as it identifies threshold values for radiogrammetric parameters which can be a predictor of the osteoporosis. The deltoid tuberosity index was found to be the most suitable of these parameters.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Osteoporosis is a common health problem in India, which leads to significant morbidity and mortality in elderly individuals. Lack of knowledge and awareness among medical professionals is one of the important barriers in management of these patients. Therefore, this study was conducted to assess knowledge pertaining to diagnosis and treatment of osteoporosis among a group of Indian medical practitioners. METHODS The study participants included 222 allopathic medical professionals, either graduate or postgraduate working in primary or secondary health care levels. They were assessed using a previously validated Fogelman's multiple choice questionnaire. Out of a total of 18 questions, four questions pertained to knowledge of diagnosis, three questions to treatment decisions, one question to assess knowledge regarding recommended dosage of vitamin D and calcium supplementation, five questions concerned medication use, and the rest to assess attitude and practices. The correct answers were converted into scores and expressed as percentages with a maximum of 100. RESULTS The mean total score among them was 22.5%, which was quite low. Almost all of them had a score of less than 50%. Medical practitioners performed better in diagnosis-related questions, (19.4% answered all options correctly) than in medication knowledge (no correct response regarding side effects and 2% regarding contraindications). In treatment-related decisions, 37.4% answered correctly for duration of treatment, and 59% answered correctly for treatment goal. Only 1.4% of them were able to answer correctly regarding recommended calcium and vitamin D intake. Professional literature, conferences, and Continuing Medical Education (CME's) were regarded as the main sources of information on the subject by 40% of practitioners. CONCLUSION This study showed suboptimal knowledge among a group of medical professionals regarding various aspects of diagnosis and management of osteoporosis, and it stipulates the need for escalating the efforts to improve their knowledge regarding various aspects of osteoporosis.

Abstract
We aimed to estimate metabolic bone profile in a large cohort of healthy, adult Indian population to generate reference standards of serum calcium, phosphate and alkaline phosphatase (ALP), 25 (OH) Vitamin D and iPTH, and also to find out the prevalence of Vitamin D deficiency in healthy population. Apparently healthy people in the age group of 20-80 years, residing in the union territory of Chandigarh were chosen. Fasting samples for serum calcium, phosphate, albumin, alkaline phosphatase (ALP), 25 (OH) D and iPTH were collected and were processed on the same day. We recruited 930 healthy subjects from different subsectors of Chandigarh. Final analysis was done for 915 subjects. Out of this, 530 (58%) were women and 385 (42%) were men. The study participants were divided into two groups, less than and more than 50 years for the men and pre and post-menopausal for the women. The serum calcium, phosphate, ALP and iPTH were significantly higher in the post-menopausal women compared to the pre-menopausal women. The median plasma 25 (OH) D in men and women was 12.5 ng/mL and 14.3 ng/mL, respectively. 25 (OH) D deficiency was seen in 65.4% of individuals. 25 (OH) D levels co-related negatively with iPTH levels (r = - 0.4, p < 0.0001), and showed an increasing trend with age. We have thus presented metabolic bone profile of healthy, adult north Indian population. These reference values can be used for diagnosis and monitoring of various MBDs. Vitamin D deficiency is still rampant in our population in spite of increasing awareness.

Abstract
Objectives: To assess the change in the bone mineral density (BMD) score, bone-specific biomarkers (serum vitamin D3, tartrate-resistant acid phosphatase 5b [TRAP-5b], and osteocalcin), quality of life, Ayurvedic symptoms (Asthikshaya Lakshanas), and fracture risk assessment tool (FRAX) scores following treatment with Panchatikta Ghrita (PG), a classical herbal formulation as add-on therapy to calcium and vitamin D3 supplements. Study design: Randomized, open-labeled, comparative, controlled clinical study. Location: TN Medical College and BYL Nair Hospital, Mumbai, India. Study participants: Eighty adult patients, aged between 40 and 75 years, diagnosed to have osteopenia (BMD T-score between -1 and -2.5 in at least two of the three joints tested-lumbar spine L1-L4, left femur-neck, left forearm-radius total). Study intervention: Treatment group received two tablespoons of PG (10 mL in lukewarm milk) along with calcium and vitamin D3 supplements twice a day, whereas control group received only calcium and vitamin D3 supplements twice a day for a period of 12 months. Outcome measures: BMD, bone-specific biomarkers (vitamin D3, TRAP-5b, and osteocalcin), quality of life, Ayurvedic symptoms, and FRAX scores were evaluated before and at 6 and 12 months. Results: Eighty patients were enrolled; of which, 65 patients completed the study while 15 patients dropped out. Improvement in the BMD scores was observed at 6 and 12 months with the maximum benefit in the lumbar spine region. Significant improvement in the bone-specific biomarkers, namely serum vitamin D3 (p < 0.001), osteocalcin (p < 0.001), and TRAP-5b (p < 0.05), was observed in the PG-treated group compared with the standard treatment group. Improvement in the quality of life, Ayurvedic symptoms scores, and risk reduction in FRAX scores of major osteoporotic fracture risk and hip fracture risk was greater with PG, although not statistically significant. Conclusions: The study findings demonstrate that PG slows down the bone degeneration processes by its stabilizing effect on the bone-specific biomarkers, indicating its potential usefulness as preventive therapy in osteopenia. The positive improvement noted in this study needs to be confirmed in studies with a larger sample size and longer duration.

Abstract
Deficiency of vitamin D or hypovitaminosis D is widespread irrespective of age, gender, race and geography and has emerged as an important area of research. Vitamin D deficiency may lead to osteoporosis (osteomalacia in adults and rickets in children) along with calcium deficiency. Its deficiency is linked with low bone mass, weakness of muscles and increased risk of fracture. However, further research is needed to link deficiency of vitamin D with extra-skeletal consequences such as cancer, cardiovascular disease, diabetes, infections and autoimmune disorders. The causes of vitamin D deficiency include length and timing of sun exposure, amount of skin exposed, latitude, season, level of pollution in atmosphere, clothing, skin pigmentation, application of sunscreen, dietary factors and genetic factors. The primary source is sunlight, and the dietary sources include animal products such as fatty fish, food items fortified with vitamin D and supplements. Different cut-offs have been used to define hypovitaminosis D and its severity in different studies. Based on the findings from some Indian studies, a high prevalence of hypovitaminosis D was observed among different age groups. Hypovitaminosis D ranged from 84.9 to 100 per cent among school-going children, 42 to 74 per cent among pregnant women, 44.3 to 66.7 per cent among infants, 70 to 81.1 per cent among lactating mothers and 30 to 91.2 per cent among adults. To tackle the problem of hypovitaminosis D in India, vitamin D fortification in staple foods, supplementation of vitamin D along with calcium, inclusion of local fortified food items in supplementary nutrition programmes launched by the government, cooperation from stakeholders from food industry and creating awareness among physicians and the general population may help in combating the problem to some extent.

Abstract
Background & Objective: The “silent thief” of bone osteoporosis is associated with various modifiable factors, identifying these factors is important in decreasing the prevalence of this highly prevalent disease. Therefore, this study was planned to identify these risk factors for osteoporosis in premenopausal and postmenopausal Pakistani women. Methods: A total of 1205 pre and postmenopausal females between the ages of 20 to 80 years were selected. Detailed history about the socio-demographic characteristics including age, education, profession, marital and resident status was recorded. Medical and gynecological history was also taken after informed consent Bone health of females was assessed using calcaneal ultrasound bone densitometer. SPSS 22.0 was used to analyze data. Results: Univariate analysis showed that age (30-39 yrs, and 60-69 yrs), occupation (housewives) and education (secondary and primary education, illiterate) were significantly associated with low bone mass density (LBMD). Multivariate analysis showed that age 30-39 years (OR=0.25 95%CI 0.13 – 0.49), age 40-49 years (OR=0.30 95%CI 0.15 – 0.59), age 50-59 years (OR=0.42 95%CI 0.22 – 0.79), primary education (OR=3.83, 95%CI 2.30 - 6.38) and illiteracy (OR=3.83 95%CI 2.52 – 5.82), were significantly associated with LBMD. The prevalence of osteopenia and osteoporosis was 29.8%, 27.2%, respectively, while 43% subjects had normal BMD. Conclusion: It is concluded that, within Pakistani population, the prevalence of osteopenia is high even at an early age group and the odds of having LBMD are more in less educated or illiterate women.

Abstract
The prevalence of osteoporosis is forecasted to escalate in Malaysia with an increasing elderly population. This study aimed to analyze the prevalence and the risk factors of osteoporosis among middle-aged and elderly Chinese Malaysians. Three hundred sixty seven Malaysian Chinese aged ≥40 years in Klang Valley, Malaysia, were recruited. All subjects completed a structured questionnaire comprised of demographic details, medical history, diet, and lifestyle practices. Body anthropometry and bone mineral density measurements were also performed. The relationship between bone health status and risk factors was determined using multivariate logistic regression. Fifteen-point-three percent of the overall study population and 32.6% of those aged ≥71 years had osteoporosis. The prevalence of osteoporosis among women (18.9%) was higher than men (11.5%). The significant predictors of osteoporosis were age, body weight, and low monthly income. Lean mass, low education level, and being underweight predicted osteoporosis in women. Lean mass was the only significant predictor of osteoporosis in men. Overall, 15.3% of the Malaysian Chinese aged ≥40 years from Klang Valley, Malaysia, had osteoporosis. Osteoporosis was associated positively with increased age and low monthly income and negatively with body weight. Therefore, osteoporosis preventive strategies targeting Chinese elderly from a low socioeconomic background is necessary.

Abstract
Background:
Osteoporosis is a major public health issue in several countries worldwide because it increases healthcare costs, and is a risk for mortality. There have been several studies that have examined BMD among the various Thai people and the regions that they inhabit.
Objective:
This study examined the distal forearm Bone Mineral Density (BMD) in men and women over 40 years of age among members of various Karen hill-tribes located in the Omkoi District, Chiang Mai Province, Thailand.
Methods:
Two hundred and sixty-two subjects (180 women, 82 men), ranging from 40 to 83 years old were recruited in this study. The non-dominant distal forearm bone mineral density was assessed by using peripheral dual-energy X-ray absorptiometry (pDEXA).
Results:
The results showed that the BMD were 0.530 ± 0.065, 0.508 ± 0.087, 0.461 ± 0.098, and 0.438 ± 0.124 g/cm2 for men age 40-49 years, age 50-59 years, age 60-69 years, and ages 70-83 years, respectively. For women, the BMD were 0.392 ± 0.051, 0.337 ± 0.063, 0.232 ± 0.065, and 0.212 ± 0.069 g/cm2 among women age 40-49 years, age 50-59 years, age 60-69 years, and ages 70-83 years, respectively. BMD had decreased in post-menopause as a function of duration time after menopause.
Conclusion:
We determined the prevalence of osteoporosis of men and women of Karen hill-tribes in the Chiang Mai Province, Thailand. These findings provided important information regarding bone health in Karen hill-tribes for any healthcare planning done in the immediate future.

Abstract
OBJECTIVES Vitamin D is known to play an important role in bone mineral metabolism. Its deficiency may affect growth and status of bone markers in children. Hence, we undertook to study the status of bone markers in children with vitamin D deficiency (VDD) and impact of vitamin D3 supplementation on them. MATERIALS AND METHODS Total 468 out of 615 children and adolescents with VDD, who were given either of the three doses (600, 1000, and 2000) of vitamin D supplementation, were included in the study. These 468 children with pre- and postsupplementation preserved samples with available anthropometry, serum biochemistry, 25-hydroxy-vitamin D, and parathormone were evaluated for bone formation (procollagen type 1 amino-terminal propeptide [P1NP]) and resorption (β-cross laps [CTx]) markers. RESULTS The mean age and body mass index of these children were 11.3 ± 2.3 years (boys: 11.5 ± 2.4; girls: 12.2 ± 1.2 years; P = 0.03) and 18.1 ± 3.8 kg/m2 (boys: 18.2 ± 3.9; girls: 17.6 ± 3.2 kg/m2; P = 0.208), respectively. There were 8.8% subjects with severe, 42.7% with moderate, and 48.5% with mild VDD. There was a significant decline in serum P1NP (from 691 ± 233 ng/ml to 640 ± 259 ng/ml, P < 0.001) and CTx (from 1.67 ± 0.53 ng/ml to 1.39 ± 0.51 ng/ml, P < 0.001) following supplementation. Though decline in serum P1NP and CTx levels was observed in both boys and girls, among all three supplementation groups and VDD categories, the effect was more marked in serum CTx than P1NP levels. CONCLUSIONS Vitamin D supplementation in VDD children resulted in decrease in both bone formation (P1NP) and resorption (CTx). The impact, however, was more marked on bone resorption than bone formation.

Abstract
Context: Dalbergia sissoo had shown anti-osteoporotic and fracture-healing activities in animal models of postmenopausal osteoporosis (PMO). Standardized extract of leaves of D. sissoo (SEL-Ds) was clinically evaluated for osteoporosis. Aims: To investigate the anti-osteoporotic activity of D. sissoo in PMO by dual-energy X-ray absorptiometry (DXA), biochemical markers, and effect on clinical profile. Tolerability was assessed by organ function tests and adverse events. Settings and Design: An open-labeled prospective clinical study in ambulant settings was conducted at the menopausal health-care facility of a women's hospital. Materials and Methods: Thirty women (45–69 years) were enrolled for this 1-year study. Evaluations were basally, fortnightly twice, and three monthly four times. SEL-Ds (300 mg) twice daily was administered orally. Calcium (250 mg) and Vitamin D (200 IU) were given twice a day. The efficacy of SEL-Ds was assessed by DXA-scan (spine, femur), by biochemical markers, alkaline phosphatase (ALP), tumor necrosis factor-alpha (TNF-α), and anti-inflammatory marker high-sensitivity C-reactive protein (hs-CRP). Baseline symptom changes and adverse events were carefully recorded. Statistical Analysis: Summary statistics (n, mean, standard deviation, median, and maximum and minimum values) of changes from baseline values and Student's “t-” test for P values were used. Results and Discussion: SEL-Ds was well tolerated at given dose for 1 year. Anti-osteoporotic and anti-inflammatory activities of SEL-Ds were demonstrated by reduction in TNF-α (12.04 ± 2.81–2.35 ± 1.08 pg/ml), ALP (208.75 ± 45.88–154.52 ± 37.25 IU/L), and hs-CRP (6.1 ± 0.77–3.9 ± 0.47 mg/L). BMD-score on DXA-scan also remained unchanged at majority of the bone locations (increased 13/75, unchanged 51/75, and decreased 08/75). Conclusions: D. sissoo has demonstrated anti-osteoporotic and anti-inflammatory activities as indicated by decline in circulating TNF-α along with concurrent reduction in ALP. The nondecline in BMD index in the majority confirms the anti-osteoporotic activity.

Abstract
Vitamin D deficiency is recognized as a pandemic affecting all ages and strata of population. The endogenous cutaneous synthesis of vitamin D is insufficient to maintain normal body requirement which necessitates the need for vitamin D supplementation or food-fortification. Conventional fat-soluble preparations of vitamin D have been traditionally used for prevention and therapeutic purposes. Recent advances in technology have enabled delivery of vitamin D through nanoemulsion formulations which ensure higher absorption and drug delivery. The following review briefly discusses the issues of bioavailability of nanoemulsion preparation of vitamin D vis-a-vis conventional fat soluble preparations.

Abstract
The last decade has seen a dramatic increase in general interest in and research into vitamin D, with many athletes now taking vitamin D supplements as part of their everyday dietary regimen. The most recognized role of vitamin D is its regulation of calcium homeostasis; there is a strong relationship between vitamin D and bone health in non-athletic individuals. In contrast, data have consistently failed to demonstrate any relationship between serum 25[OH]D and bone health, which may in part be due to the osteogenic stimulus of exercise. Vitamin D may interact with extra-skeletal tissues such as muscle and the immune system to modulate recovery from damaging exercise and infection risk. Given that many athletes now engage in supplementation, often consuming extreme doses of vitamin D, it is important to assess whether excessive vitamin D can be detrimental to health. It has been argued that toxic effects only occur when serum 25[OH]D concentrations are greater than 180 nmol·l-1, but data from our laboratory have suggested high-dose supplementation could be problematic. Finally, there is a paradoxical relationship between serum 25[OH]D concentration, ethnicity, and markers of bone health: Black athletes often present with low serum 25[OH]D without physiological consequences. One explanation for this could be genetic differences in vitamin D binding protein due to ethnicity, resulting in greater concentrations of bioavailable (or free) vitamin D in some ethnic groups. In the absence of any pathology, screening may be unnecessary and could result in incorrect supplementation. Data must now be re-examined, taking into consideration bioavailable or "free" vitamin D in ethnically diverse groups to enable new thresholds and target concentrations to be established; perhaps, for now, it is time to "set vitamin D free".

Abstract
BACKGROUND Fracture Risk Assessment Tool (FRAX) is a fracture prediction tool that uses clinical risk factors with or without bone mineral density (BMD). BMD is difficult to obtain in resource-limited setting. Hence, we aimed to compare fracture risk prediction by FRAX without BMD (FRAX) and FRAX with BMD (FRAX/BMD). OBJECTIVE We intended to determine if FRAX and FRAX/BMD would produce identical predictions for 10-year probability of hip fracture and major osteoporotic fracture (MOF). We also desired to study the risk factors that could help to identify the similarity of risk prediction. MATERIALS AND METHODS A retrospective review of patients who underwent BMD measurement and FRAX assessment was conducted. Men and women >50 years of age with osteopenia and osteoporosis according to the World Health Organization (WHO) definition at one or more sites were included. FRAX prediction scores were calculated with and without BMD using the FRAX India tool. RESULTS Of 239 subjects, 207 (86.61%) had identical fracture risk predictions with or without BMD in FRAX estimation. Mean age was lower (P = 0.009), whereas body mass index (BMI), hip BMD, spine BMD, and history of previous fracture were higher (P = 0.005, P < 0.001, P < 0.001, and P = 0.02, respectively) in the identical prediction group. CONCLUSION In our study, FRAX provided fracture risk prediction alike FRAX/BMD in most of the cases. FRAX is a good predictor of fractures especially in younger patients with higher BMI. Therefore, we conclude that FRAX is an effective tool to predict osteoporotic fracture risk and would be an inexpensive alternative when access to dual-energy X-ray absorptiometry (DXA) is limited.

Abstract
Although vitamin D is essential for bone health, little is known about prevalence of vitamin D deficiency and low bone mineral density (BMD) among children, especially those in developing countries. It also remains unclear whether serum 25-hydroxyvitamin D [25(OH)D] is associated with BMD among children. We investigated these questions among children and adolescents in Yinchuan (latitude: 38° N), Ningxia, an economically underdeveloped province in Northwest China. A total of 1582 children (756 boys and 826 girls), aged 6-18 years, were recruited from schools using the stratified random sampling method in fall 2015. Serum 25(OH)D concentrations were measured by enzyme-linked immunosorbent assay, and BMD was quantified by dual-energy X-ray absorptiometry. Vitamin D deficiency (defined as serum 25(OH)D ≤ 37.5 nmol/L) was present in 35.5% of study subjects. There were no clear patterns of differences in serum 25(OH)D concentrations across the four age groups compared (6-9 years, 10-13 years, 14-16 years, and 17-18 years). The prevalence of low total body less head (TBLH) BMD (defined as a Z-score of ≤ -2.0 standard deviations away from the mean BMD values of the Chinese pediatric reference population) among children examined was 1.8% and was not significantly different among the four age groups considered. Linear regression analysis revealed that age, weight, and height were significantly and positively associated with TBLH BMD and that the strongest determinant of TBLH BMD was age in boys and weight in girls. There were no significant correlations between serum 25(OH)D concentrations and BMD obtained for total body and at various skeletal sites (r ranged from -0.005 to 0.014) regardless of whether children evaluated were sufficient, insufficient, or deficient in vitamin D. In conclusion, more than one-third of children and adolescents in a Northwest Chinese city were deficient in vitamin D but only <2% of them developed low BMD.

Abstract
UNLABELLED FRAX scores were significantly higher in patients admitted with fragility fractures than controls and can be useful in choosing the right patients for bone density testing, thus using of an expensive test judiciously. PURPOSE This study was planned to compare the FRAX scores for the risk for major osteoporotic fracture (FRAX-MOF) and hip fracture (FRAX-HF) in patients with fragility fractures (cases) and those admitted for other indications (controls) in the orthopedic ward in our institute. METHODS Historical and anthropometric data were prospectively recorded from 500 consecutive patients admitted in the orthopedic ward in in Medanta, the Medicity, Gurgaon, India. The receiver operating characteristic (ROC) curves were constructed for FRAX-MOF and FRAX-HF and the area under the curve (AUC) was calculated between cases and controls. RESULTS The FRAX-MOF was significantly high in cases as compared to controls (7.34 ± 4.41 versus 5.64 ± 4.3; p = 0.001). The FRAX-HF was also significantly high in cases as compared to controls (2.95 ± 3.13 versus 1.67 ± 2.21; p < 0.001). The areas under the curves were 0.627 for FRAX-MOF and 0.654 for FRAX-HF. For FRAX-MOF, a cutoff of 2 has a 90% sensitivity, but only 15% specificity; whereas a cutoff of 10.5 had a specificity of 90% to differentiate those with and without fractures, but only 23% sensitivity. For FRAX-HF, a cutoff 0.3 had about 90% sensitivity and 20% specificity, whereas a cutoff of 3.5 had 90% specificity and 25% specificity to differentiate cases and controls. CONCLUSIONS This study compared the FRAX-MOF and FRAX-HF in patients with and without fragility fractures and derived cutoffs for practical clinical use of FRAX-MOF and FRAX-HF to optimize the use of DXA-BMD.

Abstract
BACKGROUND Vitamin D is conventionally known as sunshine vitamin and is synthesized endogenously in sunlight. Vitamin D is known to be a key regulator of bone metabolism, the function of genes, and essential for the development of the whole body. Deficiency of Vitamin D is now become a major worldwide epidemic health problem. AIM The present study was conducted with the objective of determining the prevalence of Vitamin D deficiency (VDD) in urban population of a district in south Punjab, across various characteristics of population such as gender, age, and socioeconomic status. MATERIALS AND METHODS A cross-sectional population survey was conducted in the urban population of the district. A total of 120 healthy volunteers of either sex participated and their 25-hydroxy Vitamin D concentrations in serum samples were estimated using ELISA. The participants were divided into three categories as follows: Vitamin D deficient, insufficient, or sufficient, on the basis of normal standardized serum levels of Vitamin D <20, 20-30, and >30 ng/ml, respectively. RESULTS Of 120 healthy individuals, 95% of the study participants had VDD or insufficiency and only 5% had adequate Vitamin D levels. In each age group, females showed lower Vitamin D levels as compared to males. Furthermore, high body mass index value was associated with low Vitamin D. Upper-class individuals also showed low levels of Vitamin D as compared to other socioeconomic classes' individuals. CONCLUSIONS Overall, high prevalence of VDD among the apparently healthy urban population of the district was observed and gives an alarming sign about continuously increasing prevalence of hypovitaminosis D among healthy population.

Abstract
Current guidelines recommend bone mineral density (BMD) measurement in asymptomatic men above age 70 years and vertebral fracture (VF) assessment above 80 years with T-score <-1.0 with risk factors. We studied the prevalence of osteoporosis and morphometric VF in asymptomatic males aged 60 years and above in North India. Free-living community-dwelling men (n = 241, age: mean ± standard deviation 68.0 ± 6.2 years) underwent a detailed history, physical examination, biochemical evaluation, and BMD measurements at 3 sites: lumbar spine, total hip (TH), and femoral neck (FN). Morphometric VF were assessed by instant vertebral assessment using Genant et al's semiquantitative method. We observed osteoporosis, osteopenia, and normal BMD in 19%, 56%, and 25% of subjects, respectively. The decade wise prevalence of osteoporosis in the age groups 60-70 years, 71-80 years, and >80 years was 16.9%, 17%, and 50%, respectively. Mean serum 25OHD levels were 17.2 ± 10.3 ng/mL. Vitamin D deficiency (<20 ng/mL) and secondary hyperparathyroidism (plasma intact parathyroid hormone >65 ng/mL) were present in 68.8% and 45.4%, respectively. VF were present in 29.6% subjects (grade I: 58%, grade II: 32.4%, and grade III: 8.8%). Age and iPTH had significant negative correlation with BMD at FN and TH. Serum 25OHD had no correlation with BMD at any site. The prevalence of VF was positively associated with age (p = 0.018) and negatively associated with BMD at FN (p = 0.002) and TH (p = 0.013). Osteoporosis and VF are common in asymptomatic Indian males aged 60 years and above. Screening for osteoporosis and instant vertebral assessment may be recommended earlier than currently existing guidelines.

Abstract
OBJECTIVES An understanding of bone mineral density (BMD) pattern in a population is crucial for prevention and diagnosis of osteoporosis and management of its complications in later life. This study aimed to screen the bone health status and factors associated with osteoporosis in an apparently healthy Indian population. METHODS A retrospective review of medical records was done in a tertiary-care hospital for the subjects who had undergone preventive health-check-ups that included BMD measurements at femur-neck, total-femur, and lumbar-spine. RESULTS We evaluated 524 subjects (age, 50.0 ± 12.4 years) including 41.2% female and 58.8% male subjects. Osteoporosis was present in 6.9% subjects (female, 11.1%; male, 4.2%) and osteopenia in 34% subjects (female, 40.3%; male, 29.9%). Absolute BMD was higher in male subjects (P < 0.001) compared to female subjects at all bone sites. Prevalence of osteoporosis increased with age in female subjects, but not in male subjects. Osteoporosis rates in the age-groups of 30-39, 40-49, 50-59, 60-69, and ≥70 years were 3%, 3.4%, 14.3%, 18.6%, and 36.4%, respectively in female subjects while prevalence in male subjects was 0%, 4%, 6.5%, 4.3%, and 5.6%, respectively, at lumbar spine. Height (r = 0.234-0.358), weight (r = 0.305-0.388), body mass index (r = 0.143-0.285) and physical activity (r = 0.136-0.153) were positively; and alkaline phosphatase (r = -0.133 to -0.203) was negatively correlated with BMD (all P < 0.01) at all sites. These parameters retained significant correlation after controlling for age and sex. No correlation of serum 25-hydroxy-vitamin-D and calcium was noted with BMD (P > 0.05) at any site. CONCLUSIONS Further data on absolute BMD, T scores, and prevalence rates of osteoporosis/osteopenia on multiple bone sites have been presented in this article.

Abstract
PURPOSE Vitamin D deficiency has been receiving increasing attention as a potential public health concern in low and lower-middle income countries (LMICs), of which there are currently 83. We aimed to conduct a comprehensive systematic literature review (SLR) of available data on vitamin D status and prevalence of vitamin D deficiency in all 83 LMICs. METHODS We followed the general methodology for SLRs in the area of serum 25-hydroxyvitamin D. Highest priority was placed on identifying relevant population-based studies, followed by cross-sectional studies, and to a lesser extent case-control studies. We adopted the public health convention that a prevalence of vitamin D deficiency (serum 25-hydroxyvitamin D < 25/30 nmol/L) at > 20% in the entire population and/or at-risk population subgroups (infants, children, women of child-bearing age, pregnancy) constitutes a public health issue that may warrant intervention. RESULTS Our SLR revealed that of the 83 LMICs, 65% (n = 54 countries) had no published studies with vitamin D data suitable for inclusion. Using data from the remaining third, a number of LMICs had evidence of excess burden of vitamin D deficiency in one or more population subgroup(s) using the above convention (Afghanistan, Pakistan, India, Tunisia and Mongolia) as well as possibly other LMICs, albeit with much more limited data. Several LMICs had no evidence of excess burden. CONCLUSION Vitamin D deficiency is a public health issue in some, but certainly not all, LMICs. There is a clear need for targeting public health strategies for prevention of vitamin D deficiency in those LMICs with excess burden.

Abstract
Background: Osteoporosis is a major public health problem and should be a priority for healthcare providers and policymakers as it is an important reason of morbidity, mortality, and high-cost incurred in the management of its complications such as hip fractures. This study is designed to assess the bone mineral density (BMD) variation with age, site, and sex. Study is based on diagnostic laboratory data of BMD. Methods: A retrospective analysis was conducted on a sample population of 935 persons (73.5% women, 26.4% men), who underwent dual-energy X-ray absorptiometry scan between 2015 and 2017 in a National Accreditation Board for Testing and Calibration Laboratories accredited Mumbai (Maharashtra, India) based diagnostic laboratory. Lumbar spine, right and left total femur, BMD were analyzed across age, sex, and sites. The prevalence of low BMD and osteoporosis at these sites has been estimated as per the World Health Organization criteria of osteoporosis diagnosis using T scores. Results: Overall the prevalence of osteoporosis was found to be 6.4%, 5.5%, and 16.4%, while the prevalence of low BMD was 32.6%, 32.8%, and 31.2% at right total femur, left total femur, and lumbar spine, respectively. The decline in BMD at lumbar spine is more among women and it was a consistent decline with age, while among men' decline rate was less at all three sites. Conclusion: Our study highlighted the variation of BMD at different sites of body and higher vulnerability of spine for fragility fractures. Our study has shown a sharp decline in BMD among women during transition from 5th to 6th decade which signifies association of menopause with osteoporosis. Major limitation of the study is unavailability of clinical profiles of the subjects because of which it is difficult to ascertain whether BMD estimation was a diagnostic or screening procedure. In addition, study is conducted in diagnostic lab settings, due to which it is possible to overestimate prevalence of low BMD and osteoporosis by extrapolating these findings to the community.

Abstract
PURPOSE The aim of study was to assess the prevalence of osteoporosis and changes in bone mass with increasing age and compare bone health status of apparently healthy men, premenopausal and postmenopausal women. METHODS Data were collected on anthropometric and sociodemographic factors in 421 apparently healthy Indian adults (women = 228), 40-75 years of age, in a cross-sectional study in Pune city, India. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry at two sites-lumbar spine (LS) and left femur. Individuals were classified as having osteoporosis or osteopenia based on the World Health Organization criteria of T-scores. RESULTS Mean age of study population was 53.3 ± 8.4 years. Of the total women, 44.3% were postmenopausal with 49.2 ± 3.5 years as mean age at menopause. Postmenopausal women showed a rapid decline in BMD with age till 50 years while men showed a gradual decline. Premenopausal women showed no significant decline in BMD with age (P > 0.1). Significantly lower T-scores were observed at LS in men compared to premenopausal (P < 0.05). At left femur, T-scores were lower in men compared to premenopausal women (P < 0.05) but not postmenopausal women (P > 0.1). The prevalence of osteoporosis in men at LS was lower than postmenopausal women but higher than premenopausal women. CONCLUSION In Indian men, a low T-score compared to women indicates higher susceptibility to osteoporosis. In women, menopause causes a rapid decline in BMD. Therefore, both Indian men and postmenopausal women require adequate measures to prevent osteoporosis during later years in life.

Performance of risk assessment tools for predicting osteoporosis in south Indian rural elderly men. Arch Osteoporos 2017; 12:35. [PMID: 28378274 DOI: 10.1007/s11657-017-0332-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2017] [Accepted: 03/28/2017] [Indexed: 02/03/2023]
Abstract
UNLABELLED Osteoporosis in elderly men is an under-recognized problem. In the current study, we intend to look at the performance of two risk assessment tools [OSTA and MORES] for the diagnosis of osteoporosis. Osteoporosis was seen in 1/4th of elderly men at spine and 1/6th of them at femoral neck. Both risk assessment tools were found to have good sensitivity in predicting osteoporosis at spine and femoral neck with good area under curve (AUC). PURPOSE This study attempts to look at the performance of osteoporosis self-assessment tool for Asians (OSTA) and male osteoporosis risk estimation score (MORES) for predicting osteoporosis in south Indian rural elderly men. METHODS Five hundred and twelve men above 65 years of age from a south Indian rural community were recruited by cluster random sampling. All subjects underwent detailed clinical, anthropometric, and bone mineral density measurement at lumbar spine and femoral neck using dual-energy X-ray absorptiometry scan. A T score ≤ - 2.5 was diagnostic of osteoporosis. Scores for OSTA and MORES were calculated at various cut offs, and their sensitivities and specificities for predicting osteoporosis were derived. RESULTS The prevalence of osteoporosis was found to be 16% at femoral neck and 23% at spine. OSTA with a cut-off value of ≤2 predicted osteoporosis with a sensitivity and specificity at lumbar spine of 94 and 17% and at femoral neck of 99 and 18%. The area under ROC curve for OSTA index for spine was 0.716 and for femoral neck was 0.778. MORES with a cut-off value of ≥6 predicted osteoporosis at spine with a sensitivity of 98% and specificity of 15%, and at femoral neck, they were 98 and 13%, respectively. The area under ROC curve for MORES for spine was 0.855 and for femoral neck was 0.760. CONCLUSION OSTA and MORES were found to be useful screening tools for predicting osteoporosis in Indian elderly men. These tools are simple, easy to perform, and cost effective in the context of rural Indian setting.

Abstract
OBJECTIVE To study the prevalence of bone mineral density (BMD) and osteoporosis in the distal forearm among Thai men over 40 years of age in Mae Chaem District, Chiang Mai Province, Thailand. METHODS The subjects in this study were 194 Thai men, aged between 40 and 87 years who resided in Mae Chaem District, Chiang Mai Province, Thailand. Self-administered questionnaires were used for receiving the demographic characteristics information. BMD was measured by peripheral dual energy X-ray absorptiometry at the nondominant distal forearm in all men. RESULTS The BMD was highest in the age-group 40-49 years and lowest in the age-group 70-87 years. The average T-score at the distal forearm was also highest in the age-group 40-49 years and lowest in the age-group 70-87 years. The BMD decreased as a function of age-group (p < .05). In contrast, the BMD increased as a function of weight (p < .05). Height had weak impact on the BMD in the distal forearm (p > .05). The percentage of osteopenia and osteoporosis are increased as a function of age-group in, while decreased in that of normal bone density. CONCLUSIONS We found the prevalence of osteoporosis in men who resided in Mae Chaem District, Chiang Mai Province, Thailand.

Implications for vitamin D screening. Br J Sports Med 2017; 52:522-526. [DOI: 10.1136/bjsports-2016-097130] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2016] [Revised: 05/04/2017] [Accepted: 06/28/2017] [Indexed: 11/04/2022]
Abstract
BackgroundThe association between bone mineral density (BMD) and serum25-hydroxyvitamin D (25(OH)D) concentration is weak, particularly in certain races (eg, BlackAfrican vs Caucasian) and in athletic populations. We aimed to examine if bioavailable vitamin D rather than serum 25(OH)D was related to markers of bone health within a racially diverse athletic population.MethodsIn 604 male athletes (Arab (n=327), Asian (n=48), Black (n=108), Caucasian (n=53) and Hispanic (n=68)), we measured total 25(OH)D, vitamin D-binding protein and BMD by DXA. Bioavailable vitamin D was calculated using the free hormone hypothesis.ResultsFrom 604 athletes, 21.5% (n=130) demonstrated severe 25(OH)D deficiency, 37.1% (n=224) deficiency, 26% (n=157) insufficiency and 15.4% (n=93) sufficiency. Serum 25(OH)D concentrations were not associated with BMD at any site. After adjusting for age and race, bioavailable vitamin D was associated with BMD (spine, neck and hip). Mean serum vitamin D binding protein concentrations were not associated with 25(OH)D concentrations (p=0.392).ConclusionRegardless of age or race, bioavailable vitamin D and not serum 25(OH)D was associated with BMD in a racially diverse athletic population. If vitamin D screening is warranted, clinicians should use appropriate assays to calculate vitamin D binding protein and bioavailable vitamin D levels concentrations than serum 25(OH)D. In turn, prophylactic vitamin D supplementation to ‘correct’ insufficient athletes should not be based on serum 25(OH)D measures.

Abstract
Background Osteoporosis is associated with variable morbidity and socio-economic burden and referred as a "silent epidemic" with increasing risk among Indian women. The present study was conducted to find prevalence of osteoporosis. Methods A descriptive cross-sectional study was conducted in Ranchi city with household women as participants. Data was collected by means of pre-tested structured questionnaire in Hindi language and bone status was screened utilizing calcaneal quantitative ultrasound as a diagnostic tool to estimate bone mineral density from 223 participants and statistical analysis was performed with SPSS software. Results The mean age of the participants was 37.9 (5.63) and majority (52.5%) of them were vegetarian. The prevalence of osteoporosis was 8.5% (5.2-13%) while 45.7% (39-52.5%) had osteopenia. We found no significant association of osteoporosis and osteopenia with income, physical activity, and dietary patterns on univariate analysis. There was no statistical significant difference between mean age and BMI of participant among normal, osteoporosis, and osteopenia participant (p value >0.5). Multivariate logistic regression analysis shows that 20% increase chances of risk with five years increase in age, the protective effect of physical activity (22%) and non-vegetarian diet (18%) though not statistically significant. Conclusion This study shows that significant number of women had osteopenia/osteoporosis within 35-40 years age group. Intensive information, education, and communication activities with regard to osteoporosis causative factors and preventive measures targeted to household women may play an important role, if started at young age.

Abstract
UNLABELLED Bone turnover markers (BTMs) provide important insights into the dynamics of bone remodelling and are subjected to preanalytical and ethnic variations in addition to influence of genetic and environmental factors. AIM/OBJECTIVES To derive ethnicity specific reference range for BTMs and to study their correlation with Bone Mineral Density (BMD) in a cohort of healthy postmenopausal women and their premenopausal daughters and to look at the impact of maternal bone mineral status on daughters bone health. MATERIAL AND METHODS This community based cross sectional study included 300 subjects (150 mother-daughter pairs). Demographic details were collected. Fasting blood and a second void morning urine samples were obtained for measurement of BTMs (sCTX, sPTNP1, sOC and urine DPD respectively) and bone mineral parameters. BMD was measured by DXA scan. RESULTS Osteoporosis was seen in 44·7% of the postmenopausal women. Ethnicity specific reference ranges of BTMs were derived for the study population. Significant inverse correlation was found between all BTMs (except urine DPD) and BMD(P < 0·05). Daughters of mothers with osteoporosis at spine and femoral neck had lower BMD, compared to daughters of mothers without osteoporosis(P = 0·03 & 0·05). CONCLUSION Apart from deriving the ethnicity specific reference range for BTMs and finding a significant inverse correlation between BTM and BMD, this study found significantly lower BMD in daughters of mothers with osteoporosis at spine and femoral neck implicating the probable interplay of genetic, epigenetic and similar environmental factors.

Abstract
Background & objectives: Type 2 diabetes mellitus (T2DM) is considered to be a protective factor against development of osteoporosis. But oral hypoglycaemic agents (OHA) are likely to increase the risk of osteoporosis. This study was carried out to evaluate the effect of various OHA on bone mineral density (BMD) in patients with T2DM. Methods: Forty one patients (study group) with T2DM (mean age 51.9±5.5 yr; 31 females) receiving treatment with oral hypoglycaemic agents (OHA) [thiazolidinediones alone (n=14) or in combination with other OHA (n=27)] for a period of at least three consecutive years and 41 age- and gender-matched healthy controls (mean age 51.4±5.1 yr) were included in the study. A detailed clinical history was taken and all were subjected to physical examination and recording of anthropometric data. BMD was assessed for both patients and controls. Results: The mean body mass index (kg/m2) (26.5±4.90 vs 27.3 ±5.33) and median [inter-quartile range (IQR)] duration of menopause (yr) among women [6(2-12) vs 6(1-13)] were comparable between both groups. The bone mineral density (BMD; g/cm2) at the level of neck of femur (NOF) (0.761±0.112 vs 0.762±0.110), lumbar spine antero-posterior view (LSAP) (0.849±0.127 vs 0.854±0.135); median Z-score NOF {0.100[(-0.850)-(0.550)] vs -0.200[(-0.800)-(0.600)]}, LSAP {-1.200[(-1.700)-(-0.200)] vs -1.300 [(-1.85)-(-0.400)]} were also similar in study and control groups. Presence of normal BMD (9/41 vs 8/41), osteopenia (16/41 vs 18/41) and osteoporosis (16/41 vs 15/41) were comparable between the study and control groups. No significant difference was observed in the BMD, T-scores and Z-scores at NOF and LSAP among T2DM patients treated with thiazolidinediones; those treated with other OHA and controls. Interpretation & conclusions: The present findings show that the use of OHA for a period of three years or more does not significantly affect the BMD in patients with T2DM.

Abstract
Background Worldwide hip fractures are projected to increase from 1.7 million in 1990 to 6.3 million in 2050. In India, conservative estimates suggest an annual incidence of 600,000 osteoporotic hip fractures and this is expected to increase significantly due to ageing and increase life expectancy. Protocol-based ‘care pathways’ for the management of adults, over 60 years of age, with hip fractures in high-income countries has resulted in decreased mortality rates, early hospital discharge, improved quality of life and reduction in healthcare costs. The study objectives are to determine appropriateness, acceptability and feasibility of adopting best-practice guideline or protocol-based care for the management of hip fractures among older adults in India. The study will also identify barriers and facilitators in recruiting patients and retention till the agreed follow-up period. Methods This will be a mixed-methods prospective cohort study. The quantitative data collection will involve recruitment of consecutive patients aged >50 years with an X-ray-confirmed hip fracture admitted in four tertiary care hospitals in Delhi, India, over a 2-month period. The quantitative data will be collected at three points: from patients at admission to hospital, from medical records at discharge and by telephone interviews with patients at 30 days post hip fracture. Qualitative data collection will involve key informant interviews, conducted with clinical leads and focus group discussions, conducted with groups of healthcare providers and patients and/or their carers. COM-B theoretical framework (capability, opportunity, motivation and behaviour) will be used to explore healthcare providers’ behaviour in order to facilitate development and implementation of appropriate integrated care pathway for management of older adults with hip fractures in India. Discussion The proposed study will identify gaps in best practice in the management of older people with hip fractures in tertiary care hospitals in Delhi and document barriers and facilitators to the implementation of protocol-based care through recording the contextual realities of the health systems and care-seeking behaviours. Insights into these factors will be used to facilitate the development of protocol-based management of older people with hip fractures that is appropriate, context specific and acceptable by stakeholders in a low- and middle-income country setting, such as India.

Abstract
OBJECTIVE Eldecalcitol (ELD) is an active form of vitamin D analog that has been approved for the treatment of osteoporosis in Japan. Over recent years, a number of multicenter, randomized controlled clinical trials have been conducted. Our goal is to comprehensively summarize the results from these studies. METHODS We searched the databases MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials up to February 28, 2015. Each database was searched using search terms "Eldecalcitol" and "ED-71" and the results were combined. The retrieved data from three independent clinical trials included a total of 1,332 patients with osteoporosis. After the data were pooled from three trials, RevMan software was used to conduct meta-analyses to determine the effects of ELD on bone mineral density (BMD) and bone turnover marker (BTM) type I collagen amino-terminal telopeptide (NTX). Effects of ELD on some of the bone formation and bone resorption parameters, incidence of vertebral fractures at the lower spine, and health-related quality of life (HRQOL) in patients with osteoporosis were also summarized. RESULTS With a test for overall effect Z=6.35, ELD could increase lumbar BMD (P<0.00001). In comparison with alphacalcidol, ELD suppressed the NTX level to a greater degree (test for overall effect Z=3.82,P<0.0001). ELD was also found to suppress bone alkaline phosphatase (BALP) by 19% (P<0.01) and osteocalcin by 19% (P<0.01) at the dose of 0.75 μg/day. Compared to alfacalcidol, ELD showed higher potency in suppressing serum BALP (26±9 vs 32±11 U/L,P<0.05) and amino-terminal propeptide of procollagen I (PINP) (42±15 vs 59±23 ng/mL,P<0.05). In addition, ELD was found to be more effective in reducing the incidence of vertebral fractures at the lower spine (P=0.029). CONCLUSION Our meta-analysis showed that ELD was more potent than alphacalcidol in reducing BTM (NTX). Clinical data together suggest that ELD is efficient in treating osteoporosis by increasing lumbar BMD; suppressing BTMs, including NTX, BALP, osteocalcin, and PINP; resulting in the reduction in the incidence of vertebral fractures at the lower spine; and increasing the HRQOL in patients with osteoporosis.

Abstract
Purpose/Introduction: Osteoporosis is a multifactorial and slowly emerging global health problem. The lifetime risk of dying from hip fracture is same as that from breast cancer. One out of three women between age group of 50-60 years in India suffers from osteoporosis. Indian women have an early age of onset of osteoporosis as compared to western counterparts. There is need for early diagnosis, identification of high-risk groups and prevention and treatment of osteoporosis in the Indian context. The aim of this study was to review the literature published in last decade and compare the research in India with that in rest of the world. Materials and Methods: Research articles with key words menopausal, osteoporosis and bone mineral density were searched in Pubmed from January 2004 to December 2013. Articles were categorized according to year, place and objective of the studies. Results: In India more articles were published in year 2010-11 (53.3%), while outside the country a uniform distribution of studies was observed throughout the last decade. Objective of research was screening and diagnosis (36.7%) and risk factor identification (40%) in most of the Indian studies as compared to rest of the world. Research publications on prevention and treatment of osteoporosis are less in India (20%). Conclusion: Research focusing on diagnosis, prognosis, prevention and treatment are needed in India.

Abstract
The number of women with osteoporosis, ie, with reduced bone mass and the disruption of bone architecture, is increasing in India. While data on prevalence of osteoporosis among women in India come from studies conducted in small groups spread across the country, estimates suggest that of the 230 million Indians expected to be over the age of 50 years in 2015, 20%, ie, ~46 million, are women with osteoporosis. Thus, osteoporosis is a major public health problem in Indian women. Low calcium intakes with extensive prevalence of vitamin D deficiency, increasing longevity, sex inequality, early menopause, genetic predisposition, lack of diagnostic facilities, and poor knowledge of bone health have contributed toward the high prevalence of osteoporosis. Bone health may be optimized by creating an environment to achieve peak bone mass during adolescence, maintenance of healthy bone throughout the life cycle, and prevention of bone loss postmenopausal. In Indian women, calcium, vitamin D, and bisphosphonates are the commonest first-line therapies used. The use of other drugs such as hormone replacement therapy, estrogen agonists, calcitonin, parathyroid hormone, and denosumab is decided as per the affordability and availability of treatment options. Major gaps still remain in the diagnosis and management of osteoporosis, thus highlighting the need for more structured research in this area. This review focuses on the epidemiology of osteoporosis in Indian women and available treatments.

Assessment of lean (muscle) mass and its distribution by dual energy X-ray absorptiometry in healthy Indian females. Arch Osteoporos 2014; 9:186. [PMID: 24981868 DOI: 10.1007/s11657-014-0186-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2014] [Accepted: 06/09/2014] [Indexed: 02/03/2023]
Abstract
SUMMARY Mean appendicular lean mass increased from the second decade to reach maximum in the fourth decade in Indian women. Post-menopausal females with LMM were significantly older, leaner, and had lower bone mineral density (BMD). Lean mass and ASMI were negatively correlated with age and positively with BMI and BMD at all sites. INTRODUCTION Sarcopenia is defined by low muscle mass (LMM), strength, and performance. Lean mass can be precisely measured by dual-energy X-ray absorptiometry (DXA). There is no uniform definition of LMM. We undertook this study to prepare percentile charts for lean mass, which serves as a surrogate for muscle mass, in apparently healthy Indian females and correlate it with anthropometric and bone mineral density (BMD) parameters. METHODS This cross-sectional study included 1,045 apparently healthy females who participated in a general health examination. They were evaluated for anthropometry, lean mass, and BMD. LMM was defined by appendicular skeletal muscle mass index (ASMI) of <5.5 kg/m(2) (European cutoff) and <5.11 kg/m(2) (<20th centile of this study population cutoff). The study subjects were categorized as pre-menopausal (<50 years) or post-menopausal (>50 years). RESULTS Mean age and BMI were 44.0 ± 17.1 years and 25.0 ± 5.2 kg/m(2), respectively. Mean total and appendicular lean mass (arm and leg) increased from the second decade to reach maximum in the fourth decade, and then declined. LMM was present in 341 (32.6%) and 157 (15%), respectively, with European and study-based cutoff (ASMI 5.11 kg/m(2)). Twenty percent of post-menopausal females had LMM. Post-menopausal females with LMM were significantly older, leaner, and had lower BMD. Lean mass and ASMI were negatively correlated with age and positively with BMI and BMD at all sites. CONCLUSIONS Peak muscle mass among Indian females is achieved in the fourth decade, and they have lower total and regional lean mass than other ethnic groups.

Abstract
BACKGROUND Lactase non-persistence (LNP) has been associated with the CC genotype of -13910C > T and GG genotype of -22018G > A polymorphisms present upstream of the lactase gene. Lactose intolerance (LI) is caused when gastrointestinal symptoms develop in individuals with low lactase activity. OBJECTIVE To analyse association of LNP genotype and LI symptoms with milk intake and determine whether factors such as age, gender and genotype affect LI status. SUBJECTS AND METHODS Genetic analysis and lactose tolerance test (LTT) were performed on 205 healthy Indian adults. The pattern of milk consumption was recorded using a dietary questionnaire. RESULTS LI was strongly associated with -13910CC genotype (OR = 10.28, 95% CI = 2.32-45.55, p = 0.002). Females were found to be at a higher risk of developing LI (OR = 2.47, 95% CI = 1.33-4.59, p = 0.004). The association of the ≥50 years age group with LI was marginally significant (OR = 1.86, 95% CI = 0.995-3.47, p = 0.05). Frequency and quantity of milk intake were lower in subjects belonging to the LNP genotype and LI groups (p < 0.05). CONCLUSIONS Subject study suggests that gender and genotype may be associated with development of LI. Association of age with LI was marginal. The data also indicate that LNP genotype and LI may play a role in influencing milk intake in individuals.

Abstract
Vitamin D deficiency prevails in epidemic proportions all over the Indian subcontinent, with a prevalence of 70%-100% in the general population. In India, widely consumed food items such as dairy products are rarely fortified with vitamin D. Indian socioreligious and cultural practices do not facilitate adequate sun exposure, thereby negating potential benefits of plentiful sunshine. Consequently, subclinical vitamin D deficiency is highly prevalent in both urban and rural settings, and across all socioeconomic and geographic strata. Vitamin D deficiency is likely to play an important role in the very high prevalence of rickets, osteoporosis, cardiovascular diseases, diabetes, cancer and infections such as tuberculosis in India. Fortification of staple foods with vitamin D is the most viable population based strategy to achieve vitamin D sufficiency. Unfortunately, even in advanced countries like USA and Canada, food fortification strategies with vitamin D have been only partially effective and have largely failed to attain vitamin D sufficiency. This article reviews the status of vitamin D nutrition in the Indian subcontinent and also the underlying causes for this epidemic. Implementation of population based educational and interventional strategies to combat this scourge require recognition of vitamin D deficiency as a public health problem by the governing bodies so that healthcare funds can be allocated appropriately.

Abstract
BACKGROUND Findings from recent meta-analyses of vitamin D supplementation without co-administration of calcium have not shown fracture prevention, possibly because of insufficient power or inappropriate doses, or because the intervention was not targeted to deficient populations. Despite these data, almost half of older adults (older than 50 years) continue to use these supplements. Bone mineral density can be used to detect biologically significant effects in much smaller cohorts. We investigated whether vitamin D supplementation affects bone mineral density. METHODS We searched Web of Science, Embase, and the Cochrane Database, from inception to July 8, 2012, for trials assessing the effects of vitamin D (D3 or D2, but not vitamin D metabolites) on bone mineral density. We included all randomised trials comparing interventions that differed only in vitamin D content, and which included adults (average age >20 years) without other metabolic bone diseases. We pooled data with a random effects meta-analysis with weighted mean differences and 95% CIs reported. To assess heterogeneity in results of individual studies, we used Cochran's Q statistic and the I(2) statistic. The primary endpoint was the percentage change in bone mineral density from baseline. FINDINGS Of 3930 citations identified by the search strategy, 23 studies (mean duration 23·5 months, comprising 4082 participants, 92% women, average age 59 years) met the inclusion criteria. 19 studies had mainly white populations. Mean baseline serum 25-hydroxyvitamin D concentration was less than 50 nmol/L in eight studies (n=1791). In ten studies (n=2294), individuals were given vitamin D doses less than 800 IU per day. Bone mineral density was measured at one to five sites (lumbar spine, femoral neck, total hip, trochanter, total body, or forearm) in each study, so 70 tests of statistical significance were done across the studies. There were six findings of significant benefit, two of significant detriment, and the rest were non-significant. Only one study showed benefit at more than one site. Results of our meta-analysis showed a small benefit at the femoral neck (weighted mean difference 0·8%, 95% CI 0·2-1·4) with heterogeneity among trials (I(2)=67%, p<0·00027). No effect at any other site was reported, including the total hip. We recorded a bias toward positive results at the femoral neck and total hip. INTERPRETATION Continuing widespread use of vitamin D for osteoporosis prevention in community-dwelling adults without specific risk factors for vitamin D deficiency seems to be inappropriate.

Abstract
OBJECTIVES Vitamin D deficiency (VDD) is a global problem. Not all patients with VDD have clinical manifestations or secondary hyperparathyroidism. We studied the interaction between serum 25-hydroxy vitamin D (25OHD), parathormone (PTH) and bone mineral density (BMD) in Indian adolescents and adults. DESIGN Population survey. PATIENTS A total of 1829 adolescents and 1346 adults aged 50 years and above were analysed in this study. MEASUREMENTS Serum biochemistry, 25OHD, PTH and BMD were estimated. Subjects were grouped according to quartiles of serum PTH. VDD was defined as severe (25OHD ≤ 5 ng/ml), moderate (25OHD ≤ 10 ng/ml) and mild (25OHD ≤ 20 ng/ml) and secondary hyperparathyroidism (SHPT) when serum PTH levels >65 pg/ml. RESULTS Only 30-40% of subjects with moderate and severe VDD, respectively, had SHPT. BMD decreased from Quartile 1 to Quartile 4 of PTH at all sites among adolescents and adults, with only a marginal decline in serum 25OHD levels between these quartiles. Further, within each PTH quartile, there was no difference in BMD according to categories of VDD. Analysing BMD in the different PTH quartiles, the PTH cut-offs beyond which BMD showed a significant decline, was 35 pg/ml in adolescents and 53 pg/ml in adults. CONCLUSIONS Less than half of the subjects with VDD have SHPT. BMD levels start to decline at PTH values currently considered to be normal. These data suggest the need to redefine SHPT in different age groups keeping in mind the relationship between PTH and BMD. This may also influence the decision to supplement subjects with VDD.
