Ke C, Zhang X, Wang X. Association between dietary inflammatory index and all-cause mortality in patients with osteopenia or osteoporosis: A retrospective cohort study from the NHANES 2007-2018. Prev Med Rep 2024; 45:102826. [PMID: 39156725 PMCID: PMC11328027 DOI: 10.1016/j.pmedr.2024.102826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 07/10/2024] [Accepted: 07/10/2024] [Indexed: 08/20/2024] Open
Abstract
Objective Osteoporosis is an inflammatory disease that causes a large disease burden worldwide. Dietary inflammation index (DII), a comprehensive assessment index that reflects the pro-inflammatory/anti-inflammatory level of diet was related to multiple inflammatory diseases. This study aimed to explore the association between DII and all-cause mortality in patients with osteoporosis or osteopenia. Methods In this retrospective cohort study, data of patients aged ≥ 45 years diagnosed as osteopenia or osteoporosis and had complete dietary intake information were extracted from the National Health and Nutrition Examination Survey (NHANES 2007-2010, 2013-2014, 2017-2018). Dietary intake information was obtained from 24-h dietary recall interviews and was used to calculate the DII score. Weighted univariate and multivariate Cox proportional hazard models were utilized to explore the association between DII and all-cause mortality in patients with osteoporosis or osteopenia, with hazard ratios (HRs) and 95 % confidence intervals (CIs). Subgroup analyses based on different age, gender and complications were further assessed this association. Results A total of 5,381 patients were included. Until December 31, 2019, 1,286 all-cause deaths occurred. After adjusting all covariates, high DII was associated with the high odds of all-cause mortality among patients with osteoporosis or osteopenia (HR=1.28, 95 %CI: 1.10-1.48), especially in the male (HR=1.38, 95 %CI: 1.06-1.78), aged < 65 years (HR=1.49, 95 %CI: 1.09-2.02), and without the history the cardiovascular disease (HR=1.30, 95 %CI: 1.03-1.65), diabetes mellitus (HR=1.27, 95 %CI: 1.06-1.52) and chronic kidney disease (HR=1.28, 95 %CI: 1.03-1.58). Conclusion A pro-inflammatory diet may have an adverse effect on the prognosis of osteoporosis patients.

Abstract
Diabetes mellitus is a metabolic and systematic disorder that requires individualized therapy. The disease leads to various consequences, resulting in the destruction of tissues and organs. The aforementioned outcomes also include bone mineral disorders, caused by medications as well as diet therapy and physical activity. Some drugs may have a beneficial effect on both bone mineral density and the risk of fractures. Nevertheless, the impact of other medications remains unknown. Focusing on pharmacotherapy in diabetes may prevent bone mineral disorders and influence both the treatment and quality of life in patients suffering from diabetes mellitus. On the other hand, anti-osteoporosis drugs, such as antiresorptive or anabolic drugs, as well as drugs with a mixed mechanism of action, may affect carbohydrate metabolism, particularly in patients with diabetes. Therefore, the treatment of diabetes as well as osteoporosis prevention are vital for this group of patients.

Abstract
Background We previously developed the Korean Calcium Assessment Tool (KCAT) for assessing the intake of calcium and vitamin D in Korean women. However, based on the Korea National Health and Nutrition Examination Survey (KNHANES) VI and VII (2013–2018), major food sources for calcium and vitamin D have changed, and the National Standard Food Composition database was updated. Therefore, the present study aimed to update the KCAT and validate the Updated KCAT. Methods A total of 285 women aged >19 years were asked to complete questionnaires of the KCAT and the Updated KCAT. Results Calcium intake did not differ significantly between the KCAT (566±245 mg/day) and the Updated KCAT (569±248 mg/day; P=0.343). A correlation coefficient of 0.99 indicated a positive correlation on calcium intake between the KCAT and the Updated KCAT, with an almost perfect agreement by Cohen’s κ coefficients (0.95). Vitamin D intake assessed by the Updated KCAT was significantly higher than that assessed by the KCAT, which was positively correlated with a moderate agreement measured by Cohen’s κ coefficients (0.41). Conclusions The present study demonstrated that the Updated KCAT was a valid tool for the rapid evaluation of calcium and vitamin D intake for Korean women.

Abstract
Menopause is a key period for health due to physiological changes, particularly of body composition (with decrease of lean mass and increase of fat mass) and of body fat distribution, leading to a higher risk for bone and muscular health and cardiometabolic health. Nutritional advices, associated to physical activity advices, may partially prevent these effects. The energy balance will be moderately negative if there is a weight gain, while the protein intake will be preserved and a regular physical activity will be increased. A Mediterranean style diet will be beneficial on cardiovascular health. Dairy products will be preserved, but restrictive and dietary exclusion will be avoided.

Abstract
This meta-analysis was performed to investigate whether calcium supplements and dairy products change obesity indices including fat mass. Original articles published in English between July 2009 and August 2019 were identified. Ten and 14 randomised controlled trials (RCTs) with ≥ 12 weeks interventions of calcium supplements and dairy products among overweight or obese adults aged ≥18 were critically reviewed. Mean difference (MD) or standardised mean difference (SMD) with 95% confidence interval (CI) were obtained using a random effect meta-analysis. Dairy products significantly changed fat mass (SMD, 95% CI; -0.40 [-0.77, -0.02]) and BMI (MD, 95% CI: -0.46 kg/m2 [-0.67, -0.26]), and calcium supplements also showed changes in fat mass (SMD, 95% CI; -0.15[-0.28, -0.02]). However, in the analysis of RCTs with low risk of bias scores, the significant changes remained only in the dairy-products intervention. Our findings suggest that dairy products without distinction of fat percentage may help reduce fat mass and BMI, but calcium supplements may not.

Abstract
An adequate calcium and vitamin D intake may play a role in preventing osteoporosis, but the contribution of the different food sources of calcium with regards to the risk of osteoporosis been barely explored. This observational study evaluated the calcium intake through a food frequency questionnaire in 126 adult women with not previously diagnosed osteoporosis undergoing Dual-energy X-ray Absorptiometry (DXA) to screen for osteoporosis, and to correlate the calcium intake with parameters of bone density, measured by DXA. Total daily calcium intake and daily intake from food were similar among women found to have osteoporosis, osteopenia or normal condition. The main food source was milk and dairy products, while calcium supplementation was consumed by only 14% of subjects, irrespectively from osteoporosis conditions. DXA parameters were not significantly correlated with total daily calcium intake and calcium from food. The present study highlighted no qualitative and quantitative differences in the consumption of food groups contributing to calcium intakes in women with and without osteoporosis.

Calcitriol combined with calcium chloride causes apoptosis in undifferentiated adipose tissue-derived human mesenchymal stem cells, but this effect decreases during adipogenic differentiation. Biomed Pharmacother 2018; 108:914-924. [PMID: 30372903 DOI: 10.1016/j.biopha.2018.09.083] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 09/01/2018] [Accepted: 09/14/2018] [Indexed: 12/20/2022] Open
Abstract
Calcitriol, the bioactive hormone of vitamin D, is currently linked to several diseases, such as obesity and gain of adipose mass, due to its liposolubility and, consequently, its sequestration by adipocytes. As rates of obesity continue to increase, research on the biology of weight gain should be encouraged. This study evaluated the effects of calcitriol combined with CaCl2 on adipose tissue-derived human mesenchymal stem cells. We evaluated the cytotoxicity of the combination by MTT assays, in which undifferentiated cells and cells undergoing adipogenic differentiation were tested for 7 and 14 days. The results demonstrated that the combination of calcitriol at the IC50 and CaCl2 at the IC20 was effective at reducing the viability of mesenchymal stem cells, but with the progression of cell differentiation towards adipocytes, cell resistance to the cytotoxic effects increased. The percentages of dead cells were 88.29, 57.45 and 28.81% for undifferentiated cells and cells exposed to differentiation medium for 7 and 14 days, respectively. Undifferentiated cells were evaluated for apoptosis in response to the same combination using Annexin V assays, and a possible onset of programmed cell death in undifferentiated cells was detected. Additionally, the combination of the compounds altered the membrane permeability of undifferentiated cells by 16 percentage points and induced cell cycle arrest in S phase due to the accumulation of damage. An evaluation of gene expression revealed the overexpression of the GADD45 and ATM genes and the underexpression of the P21, P53, ATR, BCL-2, EIF2 AK3, IGF1R, DNAse-2, ATF, MAP3K4, ENGO-G, CASP3, CASP7 and CASP8 genes. Our results provide valuable insights into the biology of obesity and may contribute to the development of new anti-obesity therapies focusing on the inhibition of adipose tissue mesenchymal stem cell hyperplasia and adipogenic differentiation.

Abstract
Identifying nutritional strategies to maintain a healthy body weight and reduce the comorbidities associated with obesity is extremely important. We aimed to investigate whether calcium and vitamin D intakes are associated with body composition measurements in a population of children and adolescents. A cross-sectional study was conducted involving 1,060 children and adolescents (65.8% females; 34.2% males) aged 9 to 19 years. Fat mass, percentage of fat mass, and fat-free mass were measured using a body composition analyzer (TANITA BC-418MA®). The mean dietary calcium and vitamin intakes were 829.66 ± 328.34 mg/day and 200.78 ± 400.91 IU/day. Linear regression analysis revealed a lack of significant association between daily calcium and vitamin D intakes and body composition measurements, after adjusting the model for age, sex, maturation status, and energy intake. Dietary calcium and vitamin D intakes do not appear to be associated with higher adiposity measurements in children and adolescents.

Abstract
BACKGROUND AND AIMS Previous studies have suggested weight-regulatory properties for several dairy nutrients, but population-based studies on dairy and body weight are inconclusive. We explored cross-sectional associations between dairy consumption and indicators of overweight. METHODS AND RESULTS We included 114,682 Dutch adults, aged ≥18 years. Dairy consumption was quantified by a food frequency questionnaire. Abdominal overweight was defined as waist circumference (WC) ≥88 cm (women) or ≥102 cm (men) (n = 37,391), overweight as BMI ≥25-30 kg/m2 (n = 44,772) and obesity as BMI ≥30 kg/m2 (n = 15,339). Associations were quantified by logistic (abdominal overweight, no/yes), multinomial logistic (BMI-defined overweight and obesity) and linear regression analyses (continuous measures of WC and BMI), and they were adjusted for relevant covariates. Total dairy showed a positive association with abdominal overweight (OR Q1 ref vs. Q5: 1.09; 95% CI: 1.04-1.14) and with BMI-defined overweight (OR Q5 1.13; 95% CI: 1.08-1.18) and obesity (OR Q5 1.09; 95% CI: 1.02-1.16). Skimmed, semi-skimmed and non-fermented dairy also showed positive associations with overweight categories. Full-fat dairy showed an inverse association with overweight and obesity (OR Q5 for obesity: 0.78; 95% CI: 0.73-0.83). Moreover, inverse associations were observed for yoghurt and custard and positive associations for milk, buttermilk, flavoured yoghurt drinks, cheese and cheese snacks. Fermented dairy, curd cheese and Dutch cheese did not show a consistent association with overweight categories. CONCLUSIONS Total, skimmed, semi-skimmed and non-fermented dairy; milk; buttermilk; flavoured yoghurt drinks; total cheese and cheese snacks showed a positive association with overweight categories, whereas full-fat dairy, custard and yoghurt showed an inverse association with overweight categories.

Abstract
Background Serum high-sensitive C-reactive protein (hs-CRP) concentrations independently predict the development of diabetes, metabolic syndrome and cardiovascular disease. However, the impact of dietary factors on serum high-sensitive C-reactive protein concentrations in diabetic patients has received limited attention. We aimed to investigate the association between dietary factors and high-sensitive C-reactive protein , among diabetic patients with and without hypertension and healthy subjects. Methods In this cross-sectional study, diabetics with ( n = 325) and without hypertension ( n = 599) and healthy individuals ( n = 1220) were recruited in Mashhad, Iran. Dietary intake was assessed by 24-h recall. Biochemical parameters including serum high-sensitive C-reactive protein were measured using standard protocols. Stepwise multiple regression analysis was used to predict whether serum high-sensitive C-reactive protein concentration was associated with dietary constituents. Results High-sensitive C-reactive protein was significantly higher among hypertensive and non-hypertensive diabetic patients compared with healthy subjects ( P < 0.001). The dietary intake of zinc + 6.4% and calcium -3.4% and body mass index +3.9% explained approximately 13.7% of the variation in serum high-sensitive C-reactive protein among diabetic hypertensive patients. Approximately 9.7% of the variation in serum high-sensitive C-reactive protein in diabetic non-hypertensive patients could be explained by body mass index, and intake of sodium, iron and cholesterol. In the healthy subjects, approximately 4.4% of the total variation in serum high-sensitive C-reactive protein concentration could be explained by cholesterol consumption and waist circumference. Conclusion Serum high-sensitive C-reactive protein concentrations were found to be a significant predictor for hypertensive and non-hypertensive diabetic subjects. There was a significant association between dietary factors include zinc, iron, sodium and cholesterol and serum high-sensitive C-reactive protein, while there was an inverse association between dietary calcium and serum high-sensitive C-reactive protein in diabetic hypertensive individuals.

Abstract
Inadequate calcium and vitamin D intake is a possible risk factor of osteoporosis. Our purposes were to estimate calcium and vitamin D intake in Korean women, and to determine associated risk factors for low calcium and vitamin D intake. This is a multicenter, hospital-based, and cross-sectional study on osteoporosis. In this study, 1516 women of 50 years or older were involved. Dietary calcium and vitamin D intake were evaluated using the self-reporting KCAT questionnaire. Average daily calcium intake was 662.8 ± 473.8 mg, and vitamin D intake 9.5 ± 10.7 μg. In multivariate analysis, older age (OR 1.02, 95 % CI 1.00-1.04, p = 0.001), and rural residence (OR 2.43, 95 % CI 1.34-4.43, p = 0.004) were significant risk factors for lower calcium intake, and older age (OR 1.03, 95 % CI 1.02-1.04, p < 0.001), and rural residence (OR 1.85, 95 % CI 1.10-3.11, p < 0.001) were significant risk factors for lower vitamin D intake. About 70 % of women aged 50 years or older had calcium and vitamin D intake below the recommended dietary intake. Older age and rural residence were significant risk factors for lower calcium and vitamin D intake in Korean women.

Background The main purpose of this study was to explore the associations between frequency of vegetables intake and osteoporosis (OP) in Chinese postmenopausal women. Methods We conducted a large-scale, community-based, cross-sectional study to investigate the associations by using self-report questionnaire to access frequency of vegetables intake. The total of 1903 participants was available to data analysis in this study. Multiple regression models to include frequency of vegetables variable were performed to investigate the relationships for OP, after controlling for confounding factors. Results Multiple regression analysis indicated that the frequency of vegetables intake was independently and significantly associated with OP (P < 0.1 for model 1 and model 2). The postmenopausal women with high frequency of vegetables intake had a higher prevalence of OP. Conclusion The findings indicated that frequency of vegetables intake was independently and significantly associated with OP. The prevalence of OP was more frequent in Chinese postmenopausal women preferring vegetables food habits.

Abstract
Background Inadequate calcium and vitamin D intake is a possible risk factor of osteoporosis. Our purposes were to estimate calcium and vitamin D intake in women with osteoporotic fractures, to determine associated factors for low calcium and vitamin D intake, and to evaluate the effects of calcium and vitamin D intake on bone mineral density (BMD). Methods This is a multicenter, hospital-based, and cross-sectional study involving 277 women with osteoporotic fractures. Dietary calcium and vitamin D intake were evaluated using the Korean Calcium Assessment Tool (KCAT) self-reported questionnaire. BMD was measured by dual energy X-ray absorptiometry (DXA) in the lumbar spine and femoral neck. Results Average daily calcium and vitamin D intake was 503.7±274.7 mg and 7.5±12.6 µg, respectively. Patients with low calcium intake had less family history of osteoporosis and were older. There was a negative correlation between age and calcium intake (r=-0.14; P=0.019). In multivariate analysis, calcium intake showed a positive correlation with BMD of femoral neck (β=0.0005, P=0.021). Conclusions About 80% of patients with osteoporotic fracture had calcium and vitamin D intake below the recommended dietary intake. Low calcium intake was associated with no family history of osteoporosis and older age. Dietary calcium intake showed positive effect on BMD.

Abstract
PURPOSE Osteoporosis is a chronic disease and an important health and social burden due to its worldwide prevalence. Literature and clinical experience report incomplete adherence to the therapy. This retrospective observational study aimed at assessing the adherence to first-line antiosteoporosis drugs (AODs; reimbursed by the National Health System, according to the Italian Medicine Agency recommendation number 79), alendronate or risedronate, with or without calcium and/or vitamin D supplements, in a real, Italian clinical setting. PATIENTS AND METHODS Analyses were carried out on data present in the ARNO Observatory, a population-based patient-centric Italian database. From a population of 5,808,832 inhabitants with available data, a cohort of 3.3 million of patients aged ≥40 years was selected. New users of first-line AODs as monotherapy (accrual period, 2007-2009) were followed up over 3 years to assess adherence at 6, 12, and 36 months to AODs and to supplements and related determinants. RESULTS Approximately 40,000 new users were identified: mostly women, aged on average (standard deviation) 71±10 years. Alendronate was the most prescribed (38.2% of patients), followed by risedronate (34.9%) and alendronate with colecalciferol as a fixed-dose combination (25.8%). Adherence at the 6-month follow-up was 54%, and this constantly and significantly decreased after 1 year to 46%, and after 3 years to 33% (P<0.01). Adherence to the fixed-dose combination was higher than to plain alendronate throughout the follow-up period. Similarly, adherence to supplements constantly decreased with the duration of treatment. Women and patients aged >50 years were more likely to adhere to treatment regimen (P<0.001). The use of drugs for peptic ulcer and gastroesophageal reflux disease and of corticosteroids for systemic use were significantly associated with high adherence at different times. Polytherapy (>5 drugs), cardiovascular, and neurological therapies were significantly associated with low adherence throughout the follow-up period. CONCLUSION In a huge clinical practice sample, this study highlights suboptimal adherence to first-line AODs and to supplements and important determinants, such as concomitant therapies.

Abstract
Calcium and vitamin D are essential components for bone health, thus calcium and vitamin D supplementation is an important strategy in the management of osteoporosis. However, the benefit of calcium and vitamin D supplementation on bone health is still controversial. Moreover, potentially harmful effects of excessive calcium supplementation on cardiovascular health are recently suggested. Too high a level of vitamin D has been also reported to have several, possibly related, harmful events. Korea is well known for low dietary calcium intake and vitamin D deficiency in its population. This position statement developed the following recommendation for adequate levels of calcium and vitamin D intake in Korean, postmenopausal women and men older than 50 years: Adequate calcium intake and optimal vitamin D level are essential for preventing and treating osteoporosis in postmenopausal women and men older than 50 years. We recommend a daily calcium intake of 800 to 1,000 mg/day. Food remains the best source of calcium; however calcium supplements should be considered when dietary intake of calcium is inadequate. We recommend dietary vitamin D intake of more than 800 IU per day, a level which appears to reduce the risk of fractures. When vitamin D deficiency is suspected, serum 25-hydroxy-vitamin D (25-[OH]D) level should be tested. We suggest that a serum 25-(OH)D level greater than 20 ng/mL is generally appropriate for prevention of osteoporosis. However, a serum 25-(OH)D level greater than 30 ng/mL is probably helpful for management of osteoporosis and prevention of fractures.

Abstract
UNLABELLED Non-linearity is a likely phenomenon in bone metabolism, but is often ignored in pertinent epidemiological studies. Using NHANES III data on calcium intake and bone mineral density, the most important non-linear methods are introduced and discussed. The results should motivate researchers to consider non-linearity in this field more frequently. INTRODUCTION Many relationships in bone metabolism and homeostasis are likely to follow non-linear patterns. Detailed dose-response analyses allowing for non-linear associations nonetheless remain scarce in this field. METHODS A detailed analysis of NHANES III data on dietary calcium intake and bone mineral density was used to demonstrate the application and some of the challenges of the most important dose-response methods, including LOESS, categorical analysis, fractional polynomials, restricted cubic splines, and segmented regression. RESULTS The spline estimate suggested increasing bone mineral density up to a calcium intake of about 1 g/day and a plateau thereafter. In segmented regression, the break-point marking the beginning of the plateau was placed at an intake of 0.58 (95 % confidence interval, 0.33 to 0.82) g/day. Sensitivity analyses suggested a less curved dose-response in women. CONCLUSIONS Knowing about the possibilities and limitations of non-linear dose-response approaches should encourage researchers to consider these methods more frequently in studies on bone health and disease. The example analysis suggested bone mineral density to reach a plateau slightly below current calcium intake recommendations, with fairly pronounced differences of the dose-response shape by sex and menopausal status.

Abstract
CONTEXT Little is known about the interactions between dietary calcium intake and bone strength parameters in populations or areas with low calcium intake. OBJECTIVE The objective of the study was to investigate the relationship between dietary calcium intake and bone mineral density (BMD) or bone geometry in an Asian population with low calcium intake. DESIGN AND SETTING This was a cross-sectional study of data from the Korea National Health and Nutrition Examination Survey, 2008-2010. PARTICIPANTS A total of 3448 men and 3812 women older than 50 years were stratified by daily dietary calcium intake: less than 400 mg/d, 400-799 mg/d, 800-1199 mg/d, and 1200 mg/d or greater. MAIN OUTCOME MEASURES BMD was measured by dual-energy X-ray absorptiometry and the geometric index was calculated. RESULTS Mean daily calcium intake was 470 mg/d in this population. BMD in the lumbar spine (both sexes) and femoral neck (women) was significantly lower only when calcium intake was less than 400 mg/d. In men, femoral neck and total hip BMD was positively related to calcium intake up to 1200 mg/d. Calcium intake less than 400 mg/d was negatively related to femoral cortical thickness and buckling ratio. These interactions disappeared when the 25-hydroxyvitamin D level was 30 ng/mL or greater in men and 20 ng/mL or greater in women. CONCLUSIONS Low calcium intake was significantly related with low BMD and increased risk of osteoporosis. However, the association between calcium and BMD was not consistently linear, and a sufficient vitamin D level appears to compensate for the negative influences of low calcium intake on bone.

Abstract
OBJECTIVE The incidence of osteoporosis increases with age and is most frequently observed in postmenopausal women. The objective of the present population-based cohort study was to assess the influence of Ca intake from dairy sources on hip bone mineral density and hip fracture incidence in a group of Polish women over 55 years of age. DESIGN The main outcome measures included: bone mineral density, the number of previous fractures and the reported Ca intake from dairy sources, assessed by a diet questionnaire. SETTING The RAC-OST-POL Study was conducted in the District of Raciborz in the south of Poland. SUBJECTS The study was carried out in a group of 625 women, randomly recruited from the general population of women aged >55 years. RESULTS Median Ca intake from dairy products was lower in the group of women with femoral neck T-score ≤-2·5 than in the group with T-score >-2·5 (275 v. 383 mg/d; P = 0·0019). For total hip score, the difference was close to borderline significance (P = 0·0698). Median Ca intake from dairy products was lower in the group of women with previous fractures than in those without fracture history (336 v. 395 mg/d; P = 0·0254). The main dairy source of Ca in the analysed group included milk drinks, rennet cheese and milk. CONCLUSIONS Higher dairy Ca intake is recommended, since a number of the women analysed were unable to satisfy their Ca requirement exclusively from their diet.

Abstract
Previous studies have revealed that magnesium (Mg) plays a significant role in bone health; however, few studies have investigated the effects of Mg supplementation in diets with different calcium (Ca) levels on the bone status and bone metabolism in a growing stage. In this present study, we tested the effects of Mg supplementation on bone status in growing female rats, relative to Ca intake levels. A total of 40 Sprague-Dawley female rats aged 6 weeks were divided into the following four groups and fed for 12 weeks as indicated: (1) LCaAMg: low Ca (Ca, 0.1 % of total diet) and adequate Mg (Mg, 0.05 % of total diet), (2) LCaHMg: low Ca and high Mg ( Mg, 0.1 % of total diet), (3) ACaAMg: adequate Ca (Ca, 0.5 % of total diet) and adequate Mg, and (4) ACaHMg: adequate Ca and high Mg. Our results showed that Mg supplementation with the adequate Ca diet significantly increased the bone mineral contents, bone size (bone area and bone thickness), and bone mineral density of femur or tibia by improving bone metabolism without changing Ca absorption. Mg supplementation significantly increased the serum osteocalcin in the adequate-Ca-diet group (p < 0.05), while the Mg supplementation significantly decreased the serum level of C-telopeptide cross-links of type I collagen in the adequate-Ca-diet group (p < 0.001). This study suggests that Mg supplementation with adequate Ca intake in the growing stage may increase the bone mineral density and bone size by improving bone metabolism.

Abstract
Background Validated simple calcium questionnaires are available to assess the intake of calcium and vitamin D in western countries, but they are not appropriate for Koreans since dairy products are not the major source of calcium and vitamin D in Korea. Thus, the objective of the present study was to develop and validate a simple and easy food frequency questionnaire (FFQ) of calcium and vitamin D for Korean. Methods Two hundred and fifty-six women were asked to complete the validated FFQ used by the Korean National Health and Nutrition Examination Survey (KNHANES) and a newly developed FFQ, the Korean Calcium Assessment Tool (KCAT), which contain the 7 food groups with 24 categories of 45 food items that are consumed frequently by Koreans. Results Calcium intake was not significantly different between the two methods; Pearson's correlation coefficient of 0.98 indicated a positive correlation, and Cohen's kappa coefficient of 0.78 indicated the subjects were correctly classified. Bland-Altman plot also showed that the mean differences of the calcium intake as assessed by the two methods were in high agreement. However, the vitamin D intake assessed by KCAT was significantly higher than that assessed by the FFQ used in KNHANES. The vitamin D intakes as assessed by the two methods were positively correlated but the two methods were in moderate agreement. Conclusions The results suggested that the newly developed KCAT was a valid tool for assessing the calcium intake in Korean women, but it might overestimate the vitamin D intake.

Abstract
In February 2013, the US Preventive Services Task Force (see www.uspreventiveservicestaskforce.org) recommended 'against daily supplementation with 400 IU or less of vitamin D3 and 1000, mg or less of calcium for the primary prevention of fractures in non institutionalized postmenopausal women', which illustrates the divergence of opinions. This review wants to shed an objective light on the importance of calcium for bone health. It cannot compete with an exhaustive analysis of the literature by an institute. It does not mention all significant references. But it highlights some pivotal studies from the past and it refers to recent studies that opened new views or added essential data to known facts. It also reflects the personal perception of the author. The first part deals mainly with intake, absorption, needs and recommendations; the second part will discuss the effects of calcium and its supplements on bone.

Abstract
An increasing number of studies indicate that dairy products, including whey protein, alleviate several disorders of the metabolic syndrome. Here, we investigated the effects of whey protein isolate (whey) in mice fed a high-fat diet hypothesising that the metabolic effects of whey would be associated with changes in the gut microbiota composition. Five-week-old male C57BL/6 mice were fed a high-fat diet ad libitum for 14 weeks with the protein source being either whey or casein. Faeces were collected at week 0, 7, and 13 and the fecal microbiota was analysed by denaturing gradient gel electrophoresis analyses of PCR-derived 16S rRNA gene (V3-region) amplicons. At the end of the study, plasma samples were collected and assayed for glucose, insulin and lipids. Whey significantly reduced body weight gain during the first four weeks of the study compared with casein (P<0.001–0.05). Hereafter weight gain was similar resulting in a 15% lower final body weight in the whey group relative to casein (34.0±1.0 g vs. 40.2±1.3 g, P<0.001). Food intake was unaffected by protein source throughout the study period. Fasting insulin was lower in the whey group (P<0.01) and glucose clearance was improved after an oral glucose challenge (P<0.05). Plasma cholesterol was lowered by whey compared to casein (P<0.001). The composition of the fecal microbiota differed between high- and low-fat groups at 13 weeks (P<0.05) whereas no difference was seen between whey and casein. In conclusion, whey initially reduced weight gain in young C57BL/6 mice fed a high-fat diet compared to casein. Although the effect on weight gain ceased, whey alleviated glucose intolerance, improved insulin sensitivity and reduced plasma cholesterol. These findings could not be explained by changes in food intake or gut microbiota composition. Further studies are needed to clarify the mechanisms behind the metabolic effects of whey.

Abstract
Hypertension and related cardiovascular diseases are reported to be associated with osteoporosis. A nutritional pathway related to dairy intake has been postulated for both diseases. The aim of this study was to assess calcium intake from dairy sources as a possible pathogenic link between osteoporosis and hypertension. This was a cross-sectional observational study performed on 3,301 postmenopausal women referred for a densitometry screening. Osteoporosis was diagnosed by lumbar dual-energy X-ray absorptiometry and hypertension was defined by blood pressure data and/or the use of antihypertensive medication. Dairy food consumption was evaluated using a weekly food-frequency questionnaire. The odds of being affected by osteoporosis, hypertension, or both diseases were calculated for quartiles of dairy intake by logistic regression analyses. Women with hypertension were affected more frequently by osteoporosis (33.2 vs. 23.3 %; p = 0.000), and there was a higher prevalence of hypertension among women with osteoporosis (32.2 vs. 22.5 %; p = 0.000). The proportion of women with hypertension, osteoporosis, and both diseases significantly increased across decreasing quartiles of dairy intake. A dairy intake in the lowest quartile was a significant predictor of osteoporosis [OR (95 % CI): 1.43 (1.12, 1.82)] and hypertension [OR (95 % CI): 1.46 (1.15, 1.85)] when compared to the highest quartile. Similarly, a low dairy intake was associated with increased odds to have both the diseases [OR (95 % CI): 1.60 (1.10, 2.34)]. From these results we conclude that osteoporosis and hypertension are associated in postmenopausal women, and a low dairy intake may increase the risk of both diseases, acting as a possible pathogenic link.

Abstract
BACKGROUND Despite the reported high prevalence of osteoporosis in the human immunodeficiency virus (HIV)-population, there have been no previous studies examining dairy calcium intake and bone mineral density (BMD) in HIV-subjects. We assessed the prevalence of low BMD in HIV-infected and uninfected subjects and analyzed the effects of calcium intake, lifestyle and HIV-related risk factors on BMD. METHODS One hundred and twelve HIV-infected subjects were consecutively enrolled. Seventy- six HIV-uninfected subjects matched for age and sex were enrolled as the control group. The HIV-subjects were interviewed about lifestyle habits and completed a weekly food-frequency questionnaire to estimate calcium intake. HIV-RNA, CD4+ T-cell count and data on antiretroviral therapy were also recorded. Both biochemical bone turnover markers and BMD, assessed by dual-energy radiographic absorptiometry (DXA) were recorded in the HIV-cases and controls. We also calculated the 10-year fracture risks using the WHO FRAX equation. RESULTS Osteoporosis prevalence was significantly higher in the HIV-cases than controls (p < 0.05). BMI values were positively correlated with BMD (p < 0.05). Vitamin D levels were lower in the HIV-subjects (p < 0.02). No correlation was found with daily calcium intake. BMI values were significantly correlated with dairy intake quartiles (p < 0.003). In HIV-subjects, the mean of FRAX score was 1.2 % for hip and 4.7 % for major osteoporotic fractures. On multivariate analysis of the lumbar spine DXA T-score, age (p < 0.005) and HIV/hepatitis C virus co-infection (p < 0.0001) were negatively correlated with BMD, while yogurt intake was a protective predictor of BMD (p < 0.05). In the femur DXA T-score, age (p < 0.01), nadir CD4 + T-cell count < 200 cells/μL (p < 0.05) and drug addiction ( p < 0.0001) were negatively correlated with BMD. CONCLUSIONS Among the foods rich in calcium, yogurt was a protective predictor of BMD in HIV-subjects. HIV/HCV co-infection, nadir CD4 + T-cell count < 200 cells/μL and drug addiction were independent predictors of severe BMD. Promoting behavioral changes in food intake and lifestyle, aimed at the primary prevention of bone disease in the chronically-infected subjects seems to be essential for implementing medical intervention in these cases.

Abstract
BACKGROUND Some studies have reported that overall diet quality affects bone status in postmenopausal women; however, the findings are inconsistent. OBJECTIVES Our primary objective was to examine the association between overall diet quality and bone turnover markers (BTMs) in postmenopausal women aged ≥45 y by using the Healthy Eating Index 2005 (HEI-2005)-a diet quality-assessment tool-developed by the US Department of Agriculture. Our secondary objective was to explore the associations between the components of the HEI-2005 and the MyPyramid food groups and BTMs. DESIGN We used cross-sectional data from NHANES 1999-2002. Multiple regression models with adjustments for relevant confounders were used to examine the relation between the total HEI-2005 score and its components and food groups and serum bone-specific alkaline phosphatase (BAP), a biomarker of bone formation, and urinary N-telopeptides/creatinine (uNTx/Cr), a biomarker of bone resorption. RESULTS No association was found between the total HEI-2005 score and BTMs. The milk group component of HEI-2005 had a significant negative linear relation with uNTx/Cr. Women in the lowest tertile of the MyPyramid milk group had the highest uNTx/Cr. Those in the highest tertile of energy-adjusted added sugar intake had the highest BAP. CONCLUSIONS Our results support the ability of a healthy diet with adequate dairy intake to promote bone health in aging women. However, we found that the HEI-2005 is not a good measure of healthy eating for optimal bone health. Further research is needed to develop an overall dietary assessment tool in relation to bone health for postmenopausal women.

Abstract
As the incidence of obesity is reaching 'epidemic' proportions, there is currently widespread interest in the impact of dietary components on body-weight and food intake regulation. The majority of data available from both epidemiological and intervention studies provide evidence of a negative but modest association between milk and dairy product consumption and BMI and other measures of adiposity, with indications that higher intakes result in increased weight loss and lean tissue maintenance during energy restriction. The purported physiological and molecular mechanisms underlying the impact of dairy constituents on adiposity are incompletely understood but may include effects on lipolysis, lipogeneis and fatty acid absorption. Furthermore, accumulating evidence indicates an impact of dairy constituents, in particular whey protein derivatives, on appetite regulation and food intake. The present review summarises available data and provides an insight into the likely contribution of dairy foods to strategies aimed at appetite regulation, weight loss or the prevention of weight gain.

Abstract
BACKGROUND Current studies indicate that older Mexican Americans take fewer calcium or calcium/vitamin D supplements than do older non-Hispanic whites. Factors associated with calcium supplement use are not completely understood in this ethnic group. OBJECTIVE The purpose of this article was to determine the prevalence of calcium or calcium/vitamin D supplementation and factors associated with their use in older Mexican Americans. METHODS A cross-sectional survey was conducted in a random sample of older Mexican Americans residing in the southwestern United States who had participated in the Hispanic Established Populations for the Epidemiologic Study of the Elderly. Self-identified Mexican Americans >or=75 years of age were enrolled through household interviews in 2004-2005. Each subject was asked to bring all prescription and nonprescription medications that they had used regularly during the previous 2 weeks to allow the interviewer to record the product names. Dosages were not recorded. Subjects were assigned to 1 of 3 categories based on their use of calcium or calcium/vitamin D supplements during the previous 2 weeks: (1) calcium supplement only, (2) calcium/vitamin D supplement, or (3) vitamin D supplement only. The subjects' sociodemographic and cultural factors, self-reported health and functional status, cognitive status, number of comorbidities, and use of antiosteoporosis medications were recorded. RESULTS A total of 2069 older Mexican Americans (1272 women, 797 men; mean age, 81.9 years) were enrolled. The overall prevalence of calcium supplement use was 10.6% (weighted). Calcium supplements were used more often by women (odds ratio [OR] = 1.76; 95% CI, 1.17-2.63), subjects with multiple comorbidities (OR = 1.29; 95% CI, 1.10-1.50), those who interviewed in English (OR = 1.59; 95% CI, 1.06-2.40), and those who used antiosteoporosis medications (OR = 3.57; 95% CI, 1.85-6.89). CONCLUSIONS Use of calcium or calcium/vitamin D supplements was low (<60%) among this group of older Mexican Americans. Men are particularly at risk. More should be done to raise awareness regarding the benefits of calcium supplementation in this ethnic group.

Abstract
High dairy intakes have been associated with lower rates of obesity in observational studies, but mechanisms to explain the association are lacking. A high intake of dairy protein reduces spontaneous food intake and may be one important mechanism, but more specific effects of dairy calcium seem to exist. We have found that high versus low calcium intakes from dairy products had no effect on 24-h energy expenditure or substrate oxidation rates, but fecal fat excretion increased approximately 2.5-fold on the high-calcium diets. In a meta-analysis of intervention studies we found that increasing dairy calcium intake by 1200mg/day resulted in increased fecal fat excretion by 5.2 (1.6-8.8) g/day. Newer research shows that humans possess taste receptors for calcium in the gastrointestinal tract and that signaling may be linked to appetite regulation. A new line of evidence suggests that an inadequate calcium intake during an energy restricted weight loss program may trigger hunger and impair compliance to the diet. These mechanisms may be part of the explanation for the protective effects of dairy products with regard to obesity and metabolic syndrome.

Abstract
Meta-analysis is typically applied to studies developed in fairly mature fields, but may be ill-suited for younger fields in which most of the evidence comes from studies that were designed for other endpoints entirely and that are often significantly underpowered for the effect in question. Here, there are no generally accepted methods for getting a grasp on the preponderance of the evidence. In this review, one way of doing so is proposed and the recently emergent literature concerning calcium intake and body composition is used as an illustration of how such an approach might be used.

Abstract
The influence of calcium and dairy food intake on energy balance is the object of a growing scientific literature. This manuscript presents the information discussed by subject experts during a symposium on calcium and obesity, initially planned to document in a comprehensive manner the role of calcium and dairy food on energy balance and body composition. This manuscript is organized into 13 propositions statements which either resume the presentation of an invited speaker or integrate recent developments in calcium-related obesity research. More specifically, the effects of calcium and dairy consumption on body weight and adiposity level, appetite, weight loss intervention outcome, lipid-lipoprotein profile and the risk to develop metabolic syndrome are discussed together with the metabolic mechanisms proposed to explain these effects. Taken together, the observations presented in this manuscript suggest that calcium and dairy food intake can influence many components of energy and fat balance, indicating that inadequate calcium/dairy intake may increase the risk of positive energy balance and of other health problems.
