Millar CL, Kiel DP, Hannan MT, Sahni S. Dairy food intake is not associated with spinal trabecular bone score in men and women: the Framingham Osteoporosis Study. Nutr J 2022; 21:26. [PMID: 35538577 PMCID: PMC9092785 DOI: 10.1186/s12937-022-00781-1] [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: 11/22/2021] [Accepted: 04/29/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Previous studies reported that dairy foods are associated with higher areal bone mineral density (BMD) in older adults. However, data on bone texture are lacking. We determined the association of dairy food intake (milk, yogurt, cheese, milk + yogurt and milk + yogurt + cheese) with spinal trabecular bone score (TBS). METHODS In this cross-sectional study, a validated semi-quantitative food frequency questionnaire was used to assess dairy food intake (servings/wk). TBS, an analysis of bone texture, was calculated from dual energy X-ray absorptiometry (DXA) scans. Sex-specific multivariable linear regression was used to estimate the association of dairy food intake (energy adjusted via residual methods) with each bone measure adjusting for covariates. RESULTS Mean age of 4,740 participants was 49 (SD: 13) years and mean milk + yogurt + cheese intake was 10.1 (SD: 8.4) servings/week in men and 10.9 (SD: 8.0) servings/week in women. There were no associations between dairy food intake and spinal TBS in adjusted models. CONCLUSIONS In this cohort of primarily healthy adults, dairy intake was not associated with bone texture.

Abstract
BACKGROUND/OBJECTIVES The purposes of this study were to evaluate the nutritional status and dietary habits of the elderly using the nutrition quotient for the elderly (NQ-E) and to analyze the differences in the NQ-E according to their levels of oral health. SUBJECTS/METHODS The survey was administered to 123 elderly people receiving congregate meal services in Seoul. The questionnaire comprised 3 domains: oral health status, general characteristics, and the NQ-E for the elderly. RESULTS The respondents were divided into 2 groups based on the average score of their levels of oral health (the group with high oral health scores: 4.42 points and the group with low oral health scores: 2.89 points). As a result of evaluating nutritional status using the NQ-E, it was found that the average NQ-E score was 58.7 points, with 46.0 points in the balance domain, 47.0 points in the diversity domain, 72.9 points in the moderation domain, and 61.8 points in the dietary behavior domain. The NQ-E score (62.3 points) of the group with high oral health scores is significantly higher than the NQ-E score (54.7 points) of the group with low oral health scores (P < 0.001). Concerning the NQ domain scores, the elderly with good oral health status had “favorable” results in terms of balance and dietary behavior, and the elderly with poor oral health status had “favorable” results only in terms of balance. CONCLUSIONS Overall, several dietary areas needed improvement in general. Those with poor oral health conditions urgently needed to improve related factors to minimize the risk of increasing imbalanced nutrition and comorbidities due to insufficient nutrition and undesirable eating habits.

Abstract
Previous studies reported that dairy foods are associated with higher areal bone mineral density (BMD) in older adults. However, data on bone strength and bone microarchitecture are lacking. We determined the association of dairy food intake (milk, yogurt, cheese, milk + yogurt, and milk + yogurt + cheese, servings/week) with high resolution peripheral quantitative computed tomography (HR-pQCT) measures of bone (failure load, cortical BMD, cortical thickness, trabecular BMD, and trabecular number). This cross-sectional study included participants with diet from a food frequency questionnaire (in 2005–2008 and/or 1998–2001) and measurements of cortical and trabecular BMD and microarchitecture at the distal tibia and radius (from HR-pQCT in 2012–2015). Sex-specific multivariable linear regression estimated the association of dairy food intake (energy adjusted) with each bone measure adjusting for covariates. Mean age was 64 (SD 8) years and total milk + yogurt + cheese intake was 10.0 (SD 6.6) and 10.6 (6.4) servings/week in men and women, respectively. No significant associations were observed for any of the dairy foods and bone microarchitecture measures except for cheese intake, which was inversely associated with cortical BMD at the radius (p = 0.001) and tibia (p = 0.002) in women alone. In this cohort of primarily healthy older men and women, dairy intake was not associated with bone microarchitecture. The findings related to cheese intake and bone microarchitecture in women warrant further investigation.

Abstract
Milk is a major source of high bioavailable calcium in most developed countries with an average calcium content of 1150 mg/L, providing a ready means of meeting the daily requirements. Its content in other minerals, phosphorus, vitamins, iodine, proteins, potassium and various nutrients is supposed to be beneficial for skeleton growth and bone strength. Studies on the effects of milk or whey extracts in animal trials and on surrogate markers in humanlike bone remodeling markers or bone mineral density and many observational studies in large cohorts show positive effects on bone health or risk of hip fracture. Nevertheless, a few contradictory epidemiological studies showed an increased risk of hip fractures in subjects drinking higher quantities of milk. These conflicting results may be due to the large number of confounders and methodological issues as recall bias. Most of the experts state that there are no proven effect of milk consumption on the risk of hip fractures in a way or the other. Of a scientific point of view, there is no reason to remove from the diet of large populations an aliment rich in calcium and other interesting nutrients.

Abstract
Previous studies found that dairy foods were associated with higher areal bone mineral density (BMD). However, data on bone geometry or compartment-specific bone density is lacking. In this cross-sectional study, the association of milk, yogurt, cheese, cream, milk+yogurt, and milk+yogurt+cheese intakes with quantitative computed tomography (QCT) measures of bone were examined, and we determined if associations were modified by serum vitamin D (25-OH D, tertiles) or age (<50 versus ≥50 years). Participants were 1522 men and 1104 women (aged 32 to 81 years, mean 50 years [men]; 55 years [women]) from the Framingham Heart Study with measures of dairy food intake (servings/wk) from a food-frequency questionnaire, volumetric BMD (vBMD, integral and trabecular, g/cm3 ), cross-sectional area (CSA, cm2 ), and estimated vertebral compressive strength (VCS, N) and 25-OH D (radioimmunoassay). Sex-specific multivariable linear regression was used to calculate the association of dairy food intake (energy adjusted) with each QCT measure, adjusting for covariates. Mean milk intake ±SD was 6 ± 7 servings/week in both men and women. In men, higher intake of milk, milk+yogurt, and milk+yogurt+cheese was associated with higher integral (p = 0.001 to 0.006) and trabecular vBMD (p = 0.006 to 0.057) and VCS (p = 0.001 to 0.010). Further, a higher cheese intake was related with higher CSA (p = 0.049). In women, no significant results were observed for the dairy foods, except for a positive association of cream intake with CSA (p = 0.016). The associations appeared to be stronger in older men. Across 25-OH D tertiles, dairy was positively associated with bone health. In summary, men with higher intakes of milk, milk+yogurt, and milk+yogurt+cheese had higher trabecular and integral vBMD and VCS but not CSA. Dairy intake seems to be most beneficial for older men, and dairy continued to have positive associations among all 25-OH D levels. © 2018 American Society for Bone and Mineral Research.

A New Approach to Assess Lifetime Dietary Patterns Finds Lower Consumption of Animal Foods with Aging in a Longitudinal Analysis of a Health-Oriented Adventist Population. Nutrients 2017; 9:nu9101118. [PMID: 29027960 PMCID: PMC5691734 DOI: 10.3390/nu9101118] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2017] [Revised: 09/22/2017] [Accepted: 10/10/2017] [Indexed: 12/17/2022] Open
Abstract
Life-course diet patterns may impact risk of disease, but little is known about dietary trends with aging. In a retrospective longitudinal analysis we estimated lifetime intake of animal products and adherence to vegetarian dietary patterns among 51,082 Adventist Health Study-2 (AHS-2) subjects using data from a reliable life-course dietary (meats, dairy, eggs) questionnaire. Results showed a marked tendency to consume fewer animal products (in total) in older years and to reduce consumption of meat, poultry and fish, but not eggs or dairy. Among the 29% of elderly subjects who during their lifetime kept the same dietary pattern (LTS) were: LTS-vegans (1.1%), LTS-lacto-ovo vegetarians (31.2%), LTS-pesco vegetarians (0.49%), LTS-semi vegetarians (3.7%), and LTS-non-vegetarians (63.5%). Among the 71% of switchers were “Converters” (59.7%) who moved towards and “Reverters” (9.1%) who moved away from vegetarian diets, and Multiverters (31.2%), who had moved in both directions. LTS-non-vegetarians, and also reverters, were more overweight and showed a less healthy lifestyle than others. We conclude that the dietary patterns are dynamic with strong trends to reduce animal foods and to adopt more vegetarian patterns with aging. The disease experience of subjects with different lifetime dietary patterns can be compared.

Abstract
Background: Previous studies showed beneficial effects of specific dairy foods on bone health in middle-aged adults.Objective: We examined the association of milk, yogurt, cheese, cream, fluid dairy (milk + yogurt), and milk + yogurt + cheese intakes with bone mineral density (BMD) and 4-y percentage of change in BMD [▵%BMD; femoral neck, trochanter, and lumbar spine (LS)]. We further assessed whether these associations were modified by vitamin D supplement use in this cohort of older adults.Methods: Food-frequency questionnaire responses, baseline BMD (hip and spine, n = 862 in 1988-1989), and follow-up BMD (n = 628 in 1992-1993) were measured in the Framingham study, a prospective cohort study of older Caucasian men and women aged 67-93 y. Outcomes included baseline BMD and ▵%BMD. Dairy-food intakes (servings per week) were converted to energy-adjusted residuals, and linear regression was used, adjusting for covariates. These associations were further examined by vitamin D supplement use.Results: The mean age of the participants was 75 y. In the full sample, dairy-food items were not associated with BMD (P = 0.11-0.99) or with ▵%BMD (P = 0.29-0.96). Among vitamin D supplement users, but not among nonusers, higher milk, fluid dairy, and milk + yogurt + cheese intakes were associated with higher LS BMD (P = 0.011-0.009). Among vitamin D supplement users, but not among nonusers, higher milk + yogurt + cheese intakes were protective against trochanter BMD loss (P = 0.009).Conclusions: In this population of older adults, higher intakes of milk, fluid dairy, and milk + yogurt + cheese were associated with higher LS BMD, and a higher intake of milk + yogurt + cheese was protective against trochanter BMD loss among vitamin D supplement users but not among nonusers. These findings underscore that the benefits of dairy intake on the skeleton may be dependent on vitamin D intake.

Abstract
Cow's milk is often severely criticized as a cause of multiple health problems, including an increased risk of fractures. A close look at the scientific literature shows a striking contradiction. On the one hand, experimental studies of surrogate markers (e.g., bone turnover markers and bone mineral density [BMD]) usually indicate benefits from drinking cow's milk. On the other, the findings from epidemiological studies are conflicting and disconcerting. In all age groups, including children and postmenopausal women, consuming cow's milk, powdered milk supplements, or whey protein is associated with a slower bone turnover and unchanged or higher BMD values. These benefits are particularly marked in populations where calcium deficiency is prevalent, for instance in Asian countries. No interventional studies have addressed the fracture risk potentially associated with drinking cow's milk. The only available data come from epidemiological observational studies, whose results are conflicting, with a lower fracture risk in some cases and no difference or a higher risk in others. Several hypotheses have been offered to explain these findings, such as a deleterious effect of D-galactose, lactose intolerance, and acid overload. Epidemiological studies face many obstacles when seeking to detect effects of a single food, particularly the multiplicity of interactions among foods. Furthermore, reliable dietary intake data must be collected over prolonged periods, often long before the occurrence of a fracture, and defective recall may therefore introduce a major yet often unrecognized bias, particularly in populations where calcium deficiency is uncommon. To date, there is no conclusive evidence that we should modify our currently high level of consumption of cow's milk.

Abstract
Food can be an excellent source of calcium. Dietary calcium is in general as well absorbed as calcium supplements, and exerts the same effects on bone. The main sources are dairy products, but also some vegetables and fruits contain considerable amounts of calcium. Mineral water can serve as a supplement. Cross-sectional, longitudinal and some interventional trials have shown positive effects on bone metabolism, bone density and bone loss. But the effect on fracture incidence is less certain, and that of milk, the most studied dairy product, still unproven.

Abstract
UNLABELLED Association between bone mineral density and bone mineral content in old age and milk consumption in adolescence, midlife, and old age was assessed. The association was strongest for milk consumption in midlife: those drinking milk daily or more often had higher bone mineral density and content in old age than those drinking milk seldom or never. INTRODUCTION The role of lifelong milk consumption for bone mineral density (BMD) and bone mineral content (BMC) in old age is not clear. Here we assess the association between hip BMD and BMC in old age and milk consumption in adolescence, midlife, and current old age. METHODS Participants of the Age, Gene/Environment Susceptibility-Reykjavik Study, aged 66-96 years (N = 4,797), reported retrospective milk intake during adolescence and midlife as well as in current old age, using a validated food frequency questionnaire. BMC of femoral neck and trochanteric area was measured by volumetric quantitative computed tomography and BMD obtained. Association was assessed using linear regression models. Differences in BMC, bone volume, and BMD in relation to milk intake were portrayed as gender-specific Z-scores. RESULTS Men consuming milk ≥ once/day during midlife had 0.21 higher Z-scores for BMD and 0.18 for BMC in femoral neck (95 % confidence interval 0.05-0.39 and 0.01-0.35, respectively) compared with < once/week. Results were comparable for trochanter. For women the results were similar, with slightly lower differences according to midlife milk consumption. For current and adolescent milk consumption, differences in Z-scores were smaller and only reached statistical significance in the case of BMD for current consumption in men, while this association was less pronounced for BMC. CONCLUSIONS Our data suggest that regular milk consumption throughout life, from adolescence to old age, is associated with higher BMC and BMD in old age, with no differences seen in bone volume. The strongest associations are seen for midlife milk consumption in both genders.

[PMID: 23371478 PMCID: PMC3641848 DOI: 10.1007/s11657-013-0119-2] [Citation(s) in RCA: 74] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2012] [Accepted: 01/07/2013] [Indexed: 02/03/2023]
Abstract
UNLABELLED Dairy foods are a complex source of essential nutrients. In this study, fluid dairy intake, specifically milk, and yogurt intakes were associated with hip but not spine bone mineral density (BMD), while cream may adversely influence BMD, suggesting that not all dairy products are equally beneficial for the skeleton. PURPOSE This study seeks to examine associations of milk, yogurt, cheese, cream, most dairy (total dairy without cream), and fluid dairy (milk + yogurt) with BMD at femoral neck (FN), trochanter (TR), and spine, and with incident hip fracture over 12-year follow-up in the Framingham Offspring Study. METHODS Three thousand two hundred twelve participants completed a food frequency questionnaire (1991–1995 or 1995–1998) and were followed for hip fracture until 2007 [corrected]. Two thousand five hundred and six participants had DXA BMD (1996-2001). Linear regression was used to estimate adjusted mean BMD while Cox-proportional hazards regression was used to estimate adjusted hazard ratios (HR) for hip fracture risk. Final models simultaneously included dairy foods adjusting for each other. RESULTS Mean baseline age was 55 (±1.6) years, range 26-85. Most dairy intake was positively associated with hip and spine BMD. Intake of fluid dairy and milk was related with hip but not spine BMD. Yogurt intake was associated with TR-BMD alone. Cheese and cream intakes were not associated with BMD. In final models, yogurt intake remained positively associated with TR-BMD, while cream tended to be negatively associated with FN-BMD. Yogurt intake showed a weak protective trend for hip fracture [HR(95%CI), ≤4 serv/week, 0.46 (0.21-1.03) vs. >4 serv/week, 0.43 (0.06-3.27)]. No other dairy groups showed a significant association (HRs range, 0.53-1.47) with limited power (n, fractures = 43). CONCLUSION Milk and yogurt intakes were associated with hip but not spine BMD, while cream may adversely influence BMD. Thus, not all dairy products are equally beneficial for the skeleton. Suggestive fracture results for milk and yogurt intakes need further confirmation.

Dietary calcium intake and calcium supplementation in hungarian patients with osteoporosis. Int J Endocrinol 2013; 2013:754328.

Abstract
Purpose. Adequate calcium intake is the basis of osteoporosis therapy-when this proves insufficient, even specific antiosteoporotic agents cannot exert their actions properly. Methods. Our representative survey analyzed the dietary intake and supplementation of calcium in 8033 Hungarian female and male (mean age: 68 years) (68.01 (CI95: 67.81-68.21)) patients with osteoporosis. Results. Mean intake from dietary sources was 665 ± 7.9 mg (68.01 (CI95: 67.81-68.21)) daily. A significant positive relationship could be detected between total dietary calcium intake and lumbar spine BMD (P = 0.045), whereas such correlation could not be demonstrated with femoral T-score. Milk consumption positively correlated with femur (P = 0.041), but not with lumbar BMD. The ingestion of one liter of milk daily increased the T-score by 0.133. Average intake from supplementation was 558 ± 6.2 mg (68.01 (CI95: 67.81-68.21)) daily. The cumulative dose of calcium-from both dietary intake and supplementation-was significantly associated with lumbar (r = 0.024, P = 0.049), but not with femur BMD (r = 0.021, P = 0.107). The currently recommended 1000-1500 mg total daily calcium intake was achieved in 34.5% of patients only. It was lower than recommended in 47.8% of the cases and substantially higher in 17.7% of subjects. Conclusions. We conclude that calcium intake in Hungarian osteoporotic patients is much lower than the current recommendation, while routinely applied calcium supplementation will result in inappropriately high calcium intake in numerous patients.

Abstract
Calcium is the most abundant cation in the human body, of which approximately 99% occurs in bone, contributing to its rigidity and strength. Bone also functions as a reservoir of Ca for its role in multiple physiologic and biochemical processes. This article aims to provide a thorough understanding of the absorptive mechanisms and factors affecting these processes to enable one to better appreciate an individual's Ca needs, and to provide a rationale for correcting Ca deficiencies. An overview of Ca requirements and suggested dosing regimens is presented, with discussion of various Ca preparations and potential toxicities of Ca treatment.

Girls' early sweetened carbonated beverage intake predicts different patterns of beverage and nutrient intake across childhood and adolescence. ACTA ACUST UNITED AC 2010; 110:543-50. [PMID: 20338280 DOI: 10.1016/j.jada.2009.12.027] [Citation(s) in RCA: 78] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2009] [Accepted: 11/02/2009] [Indexed: 11/22/2022]
Abstract
BACKGROUND Information is limited on persistence of early beverage patterns throughout childhood and adolescence and their influence on long-term dietary intake. OBJECTIVE To describe changes in beverage intake during childhood and assess beverage and nutrient intake from ages 5 to 15 years among girls who were consuming or not consuming sweetened carbonated beverages (soda) at age 5 years. DESIGN/SUBJECTS Participants were part of a longitudinal study of non-Hispanic white girls and their parents (n=170) assessed biennially from age 5 to 15 years starting fall 1996. STATISTICAL ANALYSES At each assessment, intakes of beverages (milk, fruit juice, fruit drinks, soda, and tea/coffee), energy, macronutrients, and micronutrients were assessed using three 24-hour recalls. Analyses of longitudinal changes and the interaction between beverage type and age were conducted using a mixed modeling approach. Girls were categorized as either soda consumers or nonconsumers at age 5 years. A mixed modeling approach was used to assess longitudinal differences and patterns of change in beverage and nutrient intake between soda consumption groups. RESULTS Early differences in soda intake were predictive of later soda and milk intake and of differences in selected nutrients. Relative to girls who were not consuming soda beverages at age 5 years, soda consumers at age 5 years had higher subsequent soda intake, lower milk intake, higher intake of added sugars, lower protein, fiber, vitamin D, calcium, magnesium, phosphorous, and potassium from ages 5 to 15 years. CONCLUSIONS Soda consumption at age 5 years predicted patterns of nutrient intake that persisted during childhood and into adolescence. Diets of soda consumers were higher in added sugars and lower in protein, fiber, calcium, vitamin D, magnesium, phosphorous, and potassium. Findings provide a more complex picture regarding the emergence of early beverage patterns and their predictive effects on nutrient intake across childhood and adolescence.

Abstract
OBJECTIVES The aim of our work is to evaluate the calcium intake in population of Marrakesh and its region by the translated version in Moroccan Arabic dialect of Fardellone questionnaire. SUBJECTS AND METHODS The version translated into Arabic dialect Fardellone questionnaire is tested on a sample of 1000 subjects. The subjects aged less than 15 years accounted for 30.9% (n=309), those aged 15 to 59 62% (n=620) and those aged over 60 years 7.1% (n=71). The distribution by age group is calculated on the distribution of the Moroccan population. RESULTS The study population includes 60.6% women (n=606), 39.4% of men (n=394). The mean calcium intake was respectively 5875 mg by week (that means 839 mg/day), 4899 mg by week (that means 699 mg/day), 3053 mg by week (that means 436 mg/day), in subjects aged less than 15, those aged 15 to 59, and those aged over 60 years. The average consumption of calcium per day is significantly lower than the recommended daily amount for the three age groups. Patients aged over 60 years is the age group most under nourished calcium. The comparison of both gender found a deficit higher among women than among men. CONCLUSION Evaluation of the calcium intake is an essential tool for better management of metabolic bone diseases.

Abstract
BACKGROUND Increased consumption of sweetened beverage has been linked to higher energy intake and adiposity in childhood. OBJECTIVE The objective was to assess whether beverage intake at age 5 y predicted energy intake, adiposity, and weight status across childhood and adolescence. DESIGN Participants were part of a longitudinal study of non-Hispanic white girls and their parents (n = 170) who were assessed biennially from age 5 to 15 y. At each assessment, beverage intake (milk, fruit juice, and sweetened beverages) and energy intake were assessed by using three 24-h recalls. Percentage body fat and waist circumference were measured. Height and weight were measured and used to calculate body mass index. Multiple regression analyses were used to predict the girls' adiposity. In addition, at age 5 y, girls were categorized as consuming <1, > or =1 and <2, or > or =2 servings of sweetened beverages. A mixed modeling approach was used to assess longitudinal differences and patterns of change in sweetened beverage and energy intake, adiposity, and weight status by frequency of sweetened beverage intake. RESULTS Sweetened beverage intake at age 5 y, but not milk or fruit juice intake, was positively associated with adiposity from age 5 to 15 y. Greater consumption of sweetened beverages at age 5 y (> or =2 servings/d) was associated with a higher percentage body fat, waist circumference, and weight status from age 5 to 15 y. CONCLUSION These findings provide new longitudinal evidence that early intake of sweetened beverages predicts adiposity and weight status across childhood and adolescence.

Abstract
Taurine supplementation has been shown to have a beneficial effect on femur bone mineral content in ovariectomized rats. It therefore seemed desirable to find out whether the beneficial effect of taurine on ovariectomized rats fed calcium deficient diet could also be reproduced. Forty female Sprague-Dawley rats were divided into two groups. One group was OVX and the other group received sham operation (SHAM), and received either control diet or a taurine supplemented diet for 6 weeks. All rats were fed on calcium deficient diet (AIN-93: 50% level of calcium) and deionized water. Bone mineral density (BMD) and bone mineral content (BMC) were measured in spine and femur. The serum and urine concentrations of calcium and phosphorus were determined. Bone formation was measured by serum osteocalcin and alkaline phosphatase (ALP) concentrations. Bone resorption rate was measured by deoxypyridinoline (DPD) crosslinks immunoassay and corrected for creatinine. Urinary calcium and phosphorus excretion, osteocalcin in blood and cross link value were not significantly different among the groups. Within the OVX group, the taurine supplemented group had not higher femur bone mineral content than the control group. This study established the need for a study on the taurine effect on bone with different calcium levels.

Abstract
UNLABELLED In this population-based cohort of 1,254 older Scottish women we found significant interactions between the mechanical component of self-reported habitual physical activity (PA) and dietary calcium (Ca) in BMD, independent of other risk factors. At low and/or medium Ca intakes BMD was higher amongst the most active people. INTRODUCTION Although there is general agreement that increased activity (PA) and dietary calcium (Ca) consumption may help maintain bone mass in later life and prevent fractures, the amount required remains uncertain. METHODS In 2001-2003, 1,847 postmenopausal women (mean +/- SD age: 69.3 +/- 5.5 years) underwent bone mineral density (BMD) measurement and, in 2004, 68.7% (n = 1,254) completed a bone-specific Physical Activity Questionnaire (bsPAQ) and a food frequency questionnaire. The bsPAQ measures the metabolic and mechanical components of PA. Interactions of PA and Ca in BMD were examined using ANCOVA. RESULTS Significant interactions were identified in the BMD of the lumbar spine (LS), right hip (RH) and left hip (LH), after adjustment for confounders, between tertiles of PA classified according to the mechanical component and tertiles of energy-adjusted Ca intake (ANCOVA p = 0.006, p = 0.004 and p = 0.013 respectively). For example, at medium Ca intakes LH BMD was higher by 7.8% in the highest tertile of PA compared with the lowest tertile of PA. CONCLUSIONS These data suggest that health promotion campaigns to increase PA would be most effective in populations with a low/medium calcium intake.

Abstract
OBJECTIVE The purpose of this study was to determine associations among lactose maldigestion status, perceived milk intolerance, dietary calcium intake, and bone mineral content in early adolescent girls. METHODS Subjects were 291 girls who participated in a substudy of the multiple-site project Adequate Calcium Today. Lactose maldigestion status was determined with hydrogen breath testing, and questionnaires were used to assess perceived milk intolerance. Dietary calcium intake was estimated from a semiquantitative food frequency questionnaire. Anthropometric and dual-energy x-ray absorptiometric measurements (total body, spine L2-L4, total hip, and hip femoral neck) were standardized across sites. RESULTS Of the 230 girls who completed breath hydrogen testing, 65 were Asian, 76 were Hispanic, and 89 were non-Hispanic white. A total of 100 girls experienced increases in breath hydrogen levels of >20 ppm and were classified as lactose maldigesters. Of the 246 participants who completed useable perceived milk intolerance questionnaires, 47 considered themselves to be milk intolerant. Of the 47 girls self-reporting perceived milk intolerance, 40 completed breath hydrogen testing and 22 were not maldigesters. Girls with perceived milk intolerance consumed an average of 212 mg of total food calcium per day less than girls without perceived milk intolerance. Spinal bone mineral content was significantly lower in the girls with perceived milk intolerance, compared with the girls without perceived milk intolerance. When girls with lactose maldigestion were compared with girls without lactose maldigestion, there were no significant differences in calcium intake or bone measures. CONCLUSIONS These results suggest that, starting as early as 10 years of age, self-imposed restriction of dairy foods because of perceived milk intolerance is associated with lower spinal bone mineral content values. The long-term influence of these behaviors may contribute to later risk for osteoporosis.

Abstract
OBJECTIVE Currently there are no recommendations for vitamin/mineral supplementation for lactating women but supplementation may be important, particularly for those women who choose to restrict milk intake during lactation. The objective of this study was to assess nutrient adequacy for lactating women and compare their dietary intake, including supplements, between those who restrict milk and those who do not. METHODS A cohort of 175 healthy exclusively breast-feeding women (19-45 yrs) recruited from prenatal classes were divided into milk restrictors (RS) defined as milk intake < or = 250 ml/day and non-restrictors (NRS) (>250 ml/day) and followed for six months postpartum. Participants provided repeated 24-hr dietary recalls, detailed use of vitamin/mineral supplements and reasons for restricting milk. STATISTICAL ANALYSES Observed intakes were adjusted to remove day-to-day variability. Nutrient intakes were estimated for macronutrients and vitamins C, D, thiamin, riboflavin, niacin, and minerals, calcium and zinc, with and without vitamin/mineral supplements. Chi-square was used to compare the number of RS and NRS with intakes less than the Estimated Average Requirement (EAR). RESULTS Milk restriction was practiced by 23% of the sample. Sixty per cent of RS reported protein intakes <EAR compared to 38% of NRS (chi(2) = 6.22, p < 0.05). Prior to supplementation, mean levels of calcium and vitamin D intakes for RS were below the adequate intake level (AI) and lower than NRS estimated intakes (p < 0.05). Following supplementation, mean levels of these nutrients reached AI for both groups. RS remained lower than NRS. RS had lower energy intakes than NRS (p < 0.05) but no difference in weight loss at 6 months was noted. A higher proportion of RS were below the EAR for thiamin, riboflavin and zinc. CONCLUSIONS Milk restriction compromised protein and nutrient intakes in lactating women who restricted milk to <250 mL. Vitamin/mineral supplements helped exclusively breastfeeding milk restrictors improve their vitamin D and calcium intakes. Milk restriction is not recommended during lactation and where unavoidable, nutrients provided by milk should be compensated for by other foods or supplements.

Abstract
The development and maturation of the skeletal system starts in utero. The bone-growth process starts with the addition of cells; these cells grow and incorporate materials that increase bone strength. During puberty, this process is accelerated to the degree that approximately 25% of the total bone mass is accumulated. Failure to meet the increased demand for bone-building materials during an accelerated growth period may increase fracture tendency. The greater is the bone mass at the start of puberty; the better is the final outcome at full maturity. This is in accordance with the tracking theory (keeping bone growth along a steady percentile). Nutrition and physical activity will facilitate bone accumulation from an early age. Therefore, a program for bone health that includes physical activity and nutrition should be introduced early in the prepubertal age. There are differences in the timing and rate of bone-mass accumulation of different parts of the skeleton so that measurement of one bone may not represent the whole skeleton. In addition, bone measurements using different devices cannot be compared. Therefore, until a universal standard is reached, repeated measurements of one individual should be done using the same apparatus. The choice of the apparatus should be made so that the relevant part of the skeleton is measured. Repeated measurements of bone may detect bone mass loss much earlier than the osteoporosis line is reached. This suggests that a dynamic measure of bone growth rate similar to height velocity should be adopted, since both parameters in an optimal setting follow a steady percentile and falling of the percentile in both parameters needs an etiological diagnosis.

Abstract
BACKGROUND Clinical trials have shown that calcium supplementation in children can increase bone mineral density (BMD) although this effect may not be maintained. There has been no quantitative systematic review of this intervention. OBJECTIVES . To determine the effectiveness of calcium supplementation for improving BMD in children. . To determine if any effect varies by sex, pubertal stage, ethnicity or level of physical activity, and if any effect persists after supplementation is ceased. SEARCH STRATEGY We searched CENTRAL, (Cochrane Central Register of Controlled Trials) (Issue 3, 2005), MEDLINE (1966 to 1 April 2005), EMBASE (1980 to 1 April 2005), CINAHL (1982 to 1 April 2005), AMED (1985 to 1 April 2005), MANTIS (1880 to 1 April 2005) ISI Web of Science (1945 to 1 April 2005), Food Science and Technology Abstracts (1969 to 1 April 2005) and Human Nutrition (1982 to 1 April 2005). Conference abstract books (Osteoporosis International, Journal of Bone and Mineral Research) were hand-searched. SELECTION CRITERIA Randomised controlled trials of calcium supplementation (including by food sources) compared with placebo, with a treatment period of at least 3 months in children without co-existent medical conditions affecting bone metabolism. Outcomes had to include areal or volumetric BMD, bone mineral content (BMC), or in the case of studies using quantitative ultrasound, broadband ultrasound attenuation and ultrasonic speed of sound, measured after at least 6 months of follow-up. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data including adverse events. We contacted study authors for additional information. MAIN RESULTS The 19 trials included 2859 participants, of which 1367 were randomised to supplementation and 1426 to placebo. There was no heterogeneity in the results of the main effects analyses to suggest that the studies were not comparable. There was no effect of calcium supplementation on femoral neck or lumbar spine BMD. There was a small effect on total body BMC (standardised mean difference (SMD) +0.14, 95% CI+0.01, +0.27) and upper limb BMD (SMD +0.14, 95%CI +0.04, +0.24). Only the effect in the upper limb persisted after supplementation ceased (SMD+0.14, 95%CI+0.01, +0.28). This effect is approximately equivalent to a 1.7% greater increase in supplemented groups, which at best would reduce absolute fracture risk in children by 0.1-0.2%per annum. There was no evidence of effect modification by baseline calcium intake, sex, ethnicity, physical activity or pubertal stage. Adverse events were reported infrequently and were minor. AUTHORS' CONCLUSIONS While there is a small effect of calcium supplementation in the upper limb, the increase in BMD which results is unlikely to result in a clinically significant decrease in fracture risk. The results do not support the use of calcium supplementation in healthy children as a public health intervention. These results cannot be extrapolated to children with medical conditions affecting bone metabolism.

Abstract
No previous longitudinal studies of calcium intake, anthropometry and bone health in young children with a history of avoiding cow's milk have been undertaken. We report the 2-year changes of a group of 46 Caucasian children (28 girls, l8 boys) aged 8.1+/-2.0 years (mean +/- SD) who had low calcium intakes at baseline and were short in stature, with elevated body mass index, poor skeletons and lower Z scores for both areal bone mineral density (BMD, in grams per square centimeter) and volumetric density (bone mineral apparent density, BMAD, in grams per cubic centimeter), compared with a reference population of milk drinkers. At follow-up, adverse symptoms to milk had diminished and modest increases in milk consumption and calcium intake had occurred. Total body bone mineral content (BMC) and bone area assessed by dual energy X-ray absorptiometry had increased (P<0.05), and calcium intake from all sources was associated with both these measures (P<0.05). However, although some catch-up in height had taken place, the group remained significantly shorter than the reference population (Z scores -0.39+/-1.14), with elevated body mass index (Z scores 0.46+/-1.0). The ultradistal radius BMC Z scores remained low (-0.31+/-0.98). The Z scores for BMD had improved to lie within the normal range at predominantly cortical sites (33% radius, neck of femur and hip trochanter) but had worsened at predominantly trabecular sites (ultradistal radius and lumbar spine), where values lay below those of the reference group (P<0.05). Similarly, although volumetric BMAD Z scores at the 33% radius had normalized, BMAD Z scores at the lumbar spine remained below the reference population at follow-up (-0.67+/-1.12, P<0.001). Our results demonstrate persisting height reduction, overweight and osteopenia at the ultradistal radius and lumbar spine in young milk avoiders over 2 years of follow-up.

Abstract
OBJECTIVE to compare the effect of anabolic agents on bone accretion in boys with constitutional delay of puberty (CGDP). RATIONALE it has been suggested that an appropriate timing of puberty is necessary for normal bone mineral density (BMD) acquisition. Proper bone development during childhood is the key factor in achieving higher peak bone mass during middle age, which may not be achievable in CGDP children, and thereby osteoporosis may appear at an earlier age then expected. PATIENTS AND METHODS 45 boys with CGDP aged 14-16 years were monitored longitudinally, every 3 months over 12 months with Sunlight Omnisense, a quantitative ultrasound device (Tel Aviv, Israel). The apparatus is a multi-site bone sonometer that obtains axial Speed of Sound (SOS). Based on a reference database obtained on n=1,085 (490 boys) 0-18 years, a normative curve was determined. Fifteen (14-16 years old) of the CGDP patients were treated with I.M. testovirone depot 100 mg monthly for 6 months, 15 (14-16 years old) were treated with oxandrolone 5 mg/m(2) daily for 6 months, and 15 (14-16 years old) were in an observation group. RESULTS whereas the quantitative ultrasound (QUS) Z-score had shown some increase over time in CGDP-treated patients, an increase was found in tibia Z-score from -0.5(-0.64, -0.36) to -0.4(-0.54, -0.26) and from -0.52(-0.67, -0.38) to -0.31(-0.44, -0.11) in the testosterone and oxandrolone-treated groups, respectively, [median (25%, 75%)]. An increase in radius Z-score from -0.52(-0.65, -0.25) to -0.4(-0.54, -0.15) and from -0.51(-0.61, -0.21) to -0.37(-0.47, -0.07) in the testosterone- and oxandrolone-treated groups respectively [median (25%,75%)]. Z-score SOS decreased in the observation group -0.5(-0.66, -0.3) to -0.69(-0.85, -0.54) and -0.5(-0.59, -0.41) to -0.81(-0.95, -0.55) in tibia (P = 0.032) and radius (P = 0.029), respectively. Despite the fact that QUS remained in the normative range in all patients, a clear deterioration was demonstrated in untreated CGDP patients. CONCLUSION longitudinal follow-up of patients with CGDP may detect an early pattern of deterioration of bone mass.

Abstract
A life course perspective provides a framework for understanding how food choices develop in changing temporal, social, and historical contexts. This article describes the application of life course concepts to food choices, including trajectories, transitions, turning points, lives in place and time, and timing of events in lives. A life course approach to food choice can contribute to understanding the social and biological pathways of health risk and resilience over the life span. Life course analysis is a useful research and practice tool because of the many ways in which foods, the individuals choosing them, and food choice environments are changing.

Abstract
BACKGROUND Longitudinal data regarding the influence of beverage intakes on calcium adequacy are lacking. OBJECTIVE This study evaluated calcium intake from ages 5 to 9 y as a function of mother-daughter beverage choices and as a predictor of bone mineral status. DESIGN Intakes of energy, calcium, milk, sweetened beverages, fruit juices, and non-energy-containing beverages were measured with the use of three 24-h dietary recalls in 192 non-Hispanic white girls aged 5, 7, and 9 y and their mothers. Calcium intakes from ages 5 to 9 y were categorized as either meeting or falling below recommended adequate intakes (AIs). The girls' bone mineral status was assessed with dual-energy X-ray absorptiometry at age 9 y. RESULTS The mean 5-y calcium intake was related to bone mineral density at age 9 y (beta = 0.27, P < 0.001). The girls who met the AI for calcium were not heavier (P = 0.83) but had higher energy intakes (P < 0.0001) than did the girls who consumed less than the AI. Compared with the girls who consumed less than the AI, the girls who met the AI consumed, on average, almost twice as much milk (P < 0.0001), had smaller decreases in milk intake (P < 0.01), and consumed 18% less sweetened beverages (P < 0.01) from ages 5 to 9 y; the 2 groups did not differ significantly in juice and non-energy-containing beverage intakes. The girls who met the AI were also served milk more frequently than were the girls who consumed less than the AI (P < 0.0001) and had mothers who drank milk more frequently (P < 0.01) than did the mothers of the girls who consumed less than the AI. CONCLUSIONS These findings provide new longitudinal evidence that calcium intake predicts bone mineral status during middle childhood and reflects mother-daughter beverage choice patterns that are established well before the rapid growth and bone mineralization observed in adolescence.

Abstract
BACKGROUND High calcium intakes during adolescence may increase bone acquisition. The magnitude of the effect of dietary calcium supplementation and the timing of its administration to achieve significant effects on bone health are still incompletely defined. OBJECTIVE The objective of this study was to assess the effect of calcium supplementation on bone mass accretion in postmenarcheal adolescent girls with low calcium intakes. DESIGN A double-blind, placebo-controlled calcium supplementation study was implemented. One hundred girls with a mean (+/- SD) age of 14 +/- 0.5 y with habitual calcium intakes < 800 mg/d completed a 12-mo protocol. The treatment group received a daily supplement containing 1000 mg elemental calcium. Bone mineral density (BMD) and bone mineral content (BMC) of the total body, lumbar spine, and femoral neck were determined at inclusion, 6 mo, and 12 mo. Also measured were serum concentrations of biochemical markers of bone turnover (osteocalcin and deoxypyridinoline), parathyroid hormone, and vitamin D. RESULTS The calcium-supplemented group had greater accretion of total-body BMD and lumbar spine BMD but not BMC than did the control group. Calcium supplementation appeared selectively beneficial for girls who were 2 y postmenarcheal. Calcium supplementation significantly decreased bone turnover and decreased serum parathyroid hormone concentrations. CONCLUSION Calcium supplementation of postmenarcheal girls with low calcium intakes enhances bone mineral acquisition, especially in girls > 2 y past the onset of menarche.

Abstract
UNLABELLED Studies of the effect of milk consumption on bone density have focused on white women. The applicability to other races is unclear. This study of 4316 women found a racial difference in the effect of early milk consumption on bone. Further study is required to evaluate the etiology of this difference. INTRODUCTION Early milk consumption has been found to influence bone mineral density positively throughout life. Previous studies leading to this finding focused on white women; there are no data to support the view that black women also gain an equivalent benefit from early milk consumption. MATERIALS AND METHODS Using data from the Third National Health and Nutrition Examination Survey (NHANES III), we analyzed the relationship between reported childhood and teenage milk consumption and current hip bone mineral density at four sites (femoral neck, trochanter, intertrochanter, and total hip) among postmenopausal and 20- to 39-year-old non-Hispanic white (NHW) and black (NHB) women. Potential confounding variables were accounted for in the analysis. RESULTS Controlling for age and body mass index, teenage milk consumption was significantly associated with higher bone mineral density at all four sites among both postmenopausal and 20- to 39-year-old white women, but was not associated with bone mineral density at any site among black women. A similar pattern was observed for childhood milk intake. The interaction between race and teenage milk consumption significantly explained postmenopausal bone mineral density at all sites, whereas the interaction between race and teenage milk consumption was significant at two of the four sites among the 20- to 39-year-old women. CONCLUSION The results show racial differences in the effect of early milk consumption on peak and postmenopausal bone mineral density.

Abstract
The aim of this study was to investigate the impact of magnesium-enriched, high-calcium milk on serum parathyroid hormone (PTH) and biochemical markers of bone turnover in postmenopausal women. We recruited 50 healthy postmenopausal women to take part in this randomised controlled study. Half of the women consumed two serves of high-calcium skim milk enriched with magnesium (milk group) and half consumed two serves apple drink per day (apple group), each for 4 weeks. The milk provided 1200 mg calcium and an additional 106 mg magnesium. We investigated the responses of serum PTH, as well as the serum and urinary calcium, magnesium and biochemical markers of bone turnover. There was no effect of time or drink on the clinical biochemistry, serum PTH or urine markers of bone resorption (free deoxypyridinoline and N-telopeptides). Serum C-telopeptides (CTX), another marker of bone resorption, did not change with time in the apple group. However, in the milk group, serum CTX deceased significantly from 0.43 +/- 0.04 ng/mL to 0.32 +/- 0.02 at 2 weeks (p < 0.0001) and 0.28 +/- 0.02 at 4 weeks (p < 0.0001). In the milk group, urinary calcium and magnesium each increased during the night but not during the day. Overall, these data suggest that milk has an antiresorptive effect on bone, but that this is not accompanied by measurable changes in serum PTH.

Abstract
BACKGROUND Calcium supplements increase bone mass in children, but the effect does not persist once supplementation is discontinued. OBJECTIVE The objective of this study was to determine whether milk intake during childhood and adolescence, when controlled for current calcium intake, is associated with adult bone mass (ie, bone mineral content), bone mineral density, and the incidence of osteoporotic fracture. DESIGN We used data from the third National Health and Nutrition Examination Survey of 3251 non-Hispanic, white women age >or=20 y. Bone density was measured at the hip. History of fracture of the hip, spine, or forearm was classified as a lifetime fracture (occurring after age 13 y) or an osteoporotic fracture (occurring after age 50 y). Subjects reported frequency of milk consumption during childhood (aged 5-12 y) and during adolescence (aged 13-17 y). Regression models controlled for weight, height, age, menopause and use of estrogen, physical activity, smoking, and current calcium intake. RESULTS Among women aged 20-49 y, bone mineral content was 5.6% lower in those who consumed <1 serving of milk/wk (low intake) than in those who consumed >1 serving/d (high intake) during childhood (P < 0.01). Low milk intake during adolescence was associated with a 3% reduction in hip bone mineral content and bone mineral density (P < 0.02). Among women aged >or=50 y, there was a nonlinear association between milk intake during childhood and adolescence and hip bone mineral content and bone mineral density (P < 0.04). Low milk intake during childhood was associated with a 2-fold greater risk of fracture (P < 0.05). CONCLUSION Women with low milk intake during childhood and adolescence have less bone mass in adulthood and greater risk of fracture.

Abstract
A longitudinal study of 386 healthy Black and White women aged 35-60 years was conducted to determine the effects of physical activity and other related factors on lumbar bone mineral density over 24 months. Bone mineral density of the lumbar spine, L2-L4, was measured using dual energy x-ray (Hologic 1000). Physical activity levels in three dimensions (leisure, household, and occupational) from both a lifelong and current perspective were obtained by questionnaire. Body mass index was calculated from measured weight in kilograms divided by measured height in meters squared. Calcium, caffeine, and alcohol intake was estimated using a food frequency questionnaire. Age, race, and smoking were determined by self-report. Radioimmunoassays of follicle stimulating hormone (FSH) and estradiol were used to validate self-reports of menopausal status. Multiple regression analysis revealed that race, age, weight, FSH, calcium, and years of tobacco intake formed the best model at baseline (r(2) = 0.32) and at 24 months (r(2) = 0.303). Physical activity was not a significant predictor for bone mineral density at either time point. There were cross-sectional changes of bone mineral density with race, age, and menopausal status. Black women had significantly higher bone mineral density than White women. However, an age-related decline in bone mineral density was exhibited in both Black and White women. Perimenopausal women had significantly lower bone mineral density as compared with premenopausal women. Furthermore 37 (9.6%) women at baseline and 34 (11%) at 24 months were designated at risk for fracture.

Abstract
It is widely believed that osteoporosis prevention may be best accomplished during childhood and adolescence, when bones are growing rapidly and are most sensitive to environmental influences, such as diet and physical activity. For children with chronic diseases, a variety of factors may influence normal bone mineralization, including altered growth, delayed maturation, inflammation, malabsorption, reduced physical activity, glucocorticoid exposure, and poor dietary intake. In healthy children, maintaining adequate levels of calcium intake, serum vitamin D, and weightbearing physical activity may be sufficient to prevent osteoporosis later in life. Far less is known about effective prevention and treatment of poor bone mineralization in children with chronic illness, such as CF or CD. Osteoporosis prevention and intervention measures during childhood are limited by the paucity of reference data on bone mineralization. Although it is widely recognized that puberty, skeletal maturation, and body size influence BMC and bone density, no reference data for bone mineralization are scaled to these important measures. In children with chronic disease with delayed growth and maturation, the creation of such reference data is of paramount importance. In addition, the dynamic changes that occur during growth and maturation in the structural characteristics of trabecular and cortical bone and the development of the bone-muscle unit may influence current and future fracture risk. Further research is needed to characterize these changes and their use in the assessment of bone health and fracture risk in children. Only then can the impact of treatment strategies be appreciated fully.

Abstract
Biomarkers have considerable potential in aiding the understanding of the relationship between diet and disease or health. However, to assess the role, relevance and importance of biomarkers on a case by case basis it is essential to understand and prioritise the principal diet and health issues. In the majority of cases, dietary compounds are only weakly biologically active in the short term, have multiple targets and can be both beneficial and deleterious. This poses particular problems in determining the net effect of types of foods on health. In principle, a biomarker should be able to contribute to this debate by allowing the measurement of exposure and by acting as an indicator either of a deleterious or of an enhanced health effect prior to the final outcome. In this review, the examples chosen - cancer (stomach, colon/rectal, breast); coronary heart disease and osteoporosis - reflect three major diet-related disease issues. In each case the onset of the disease has a genetic determinant which may be exacerbated or delayed by diet. Perhaps the most important factor is that in each case the disease, once manifest, is difficult to influence in a positive way by diet alone. This then suggests that the emphasis for biomarker studies should focus on predictive biomarkers which can be used to help in the development of dietary strategies which will minimise the risk and be of greater benefit.

Abstract
Milk intake constitutes an important source of dietary calcium for young girls but declines throughout childhood. Recent work shows that the intake of soft drinks may contribute to this decline. Influences on the apparent tradeoff between soft drinks and milk in young girls' diets are not well described. The objective of this research was to test a model depicting maternal beverage choices as predictors of their daughters' milk and soft drink intake. A structural equation model describing maternal influences on daughters' milk, soft drink and calcium intakes was tested using data from 180 non-Hispanic, white families with 5-y-old daughters. Mothers' calcium, milk and soft drink intakes were evaluated as predictors of their daughters' intakes. Mothers' and daughters' soft drink intakes were also examined as predictors of their own milk and calcium intakes. The model provided a good fit to the data, revealing mother-daughter similarities in beverage intake. Mothers who drank milk more frequently had daughters who drank milk more frequently and drank fewer soft drinks. For both mothers and daughters, soft drink consumption was negatively related to both milk and calcium intake. This research provides evidence that mothers' beverage choices influence the tradeoff between milk and soft drinks in their daughters' diets. In particular, mothers' milk and soft drink intakes may affect their daughters' calcium adequacy in early childhood by influencing the frequency with which their daughters consume those beverages.

Abstract
Calcium and vitamin D are useful adjunctive therapies in the prevention and treatment of osteoporosis. Peak BMD is optimally achieved with sustained optimal calcium and vitamin D intakes. Calcium and vitamin D intakes continue to be important after the third decade and into senescence. Although calcium and vitamin D are not therapies to be used alone to prevent early postmenopausal bone loss, they assume more prominent roles in late menopause and in the elderly to preserve bone health with advancing age. Calcium and vitamin D supplementation is an important adjunctive therapy to use together with antiresorptive therapies.

Abstract
Osteoporosis is a complex, multi-factorial condition characterized by reduced bone mass and impaired micro-architectural structure, leading to an increased susceptibility to fractures. Although most of the bone strength (including bone mass and quality) is genetically determined, many other factors (nutritional, environmental and life-style) also influence bone. Nutrition is important modifiable factor in the development and maintenance of bone mass and the prevention and treatment of osteoporosis. Approximately 80-90% of bone mineral content is comprised of calcium and phosphorus. Other dietary components, such as protein, magnesium, zinc, copper, iron, fluoride, vitamins D, A, C, and K are required for normal bone metabolism, while other ingested compounds not usually categorized as nutrients (e.g. caffeine, alcohol, phytoestrogens) may also impact bone health. Unraveling the interaction between different factors; nutritional, environmental, life style, and heredity help us to understand the complexity of the development of osteoporosis and subsequent fractures. This paper reviews the role of dietary components on bone health throughout different stages of life. Each nutrient is discussed separately, however the fact that many nutrients are co-dependent and simultaneously interact with genetic and environmental factors should not be neglected. The complexity of the interactions is probably the reason why there are controversial or inconsistent findings regarding the contribution of a single or a group of nutrients in bone health.

Abstract
It is unclear whether dairy foods promote bone health in all populations and whether all dairy foods are equally beneficial. The objective of this review was to determine whether scientific evidence supports the recommendation that dairy foods be consumed daily for improved bone health in the general US population. Studies were reviewed that examined the relation of dairy foods to bone health in all age, sex, and race groups. Outcomes were classified according to the strength of the evidence by using a priori guidelines and were categorized as favorable, unfavorable, or not statistically significant. Of 57 outcomes of the effects of dairy foods on bone health, 53% were not significant, 42% were favorable, and 5% were unfavorable. Of 21 stronger-evidence studies, 57% were not significant, 29% were favorable, and 14% were unfavorable. The overall ratio of favorable to unfavorable effects in the stronger studies was 2.0 (4.0 in <30-y-olds, 1.0 in 30-50-y-olds, and 1.0 in >50-y-olds). Males and ethnic minorities were severely underrepresented. Dairy foods varied widely in their content of nutrients known to affect calcium excretion and skeletal mass. Foods such as milk and yogurt are likely to be beneficial; others, such as cottage cheese, may adversely affect bone health. Of the few stronger-evidence studies of dairy foods and bone health, most had outcomes that were not significant. However, white women <30 y old are most likely to benefit. There are too few studies in males and minority ethnic groups to determine whether dairy foods promote bone health in most of the US population.

Abstract
This update focuses on the bioavailability of dietary calcium for humans. Fundamentals of calcium metabolism, intestinal absorption, urinary excretion and balance are recalled. Dietary factors, especially lactose and other milk components, influencing calcium bioavailability at intestinal and renal levels are reviewed. A critical examination of all the methods used for evaluating calcium bioavailability is made. This includes in vitro assays, classical and isotopic balances, urinary excretion, isotope labeling in the urine, plasma and bones, long term evaluation of bone mineralization and the use of biological bone markers. Importance and advantages of animal models are discussed. The state of the art in the comparative bioavailability of calcium in foods is detailed including a comparison of sources of calcium (dairy products and calcium salts) in human studies and in some animal studies, casein phosphopeptides, proteins, lactose and lactase and their relation with calcium bioavailability (in humans and rats). An update on the consumption of dairy products and bone mass is presented. Emphasis on peculiarities and advantages of calcium in milk and dairy products is given.

Abstract
Osteoporosis is a multifactorial disorder in which nutrition plays a role but does not account for the totality of the problem. 139 papers published since 1975 and describing studies of the relationship of calcium intake and bone health are briefly analyzed. Of 52 investigator-controlled calcium intervention studies, all but two showed better bone balance at high intakes, or greater bone gain during growth, or reduced bone loss in the elderly, or reduced fracture risk. This evidence firmly establishes that high calcium intakes promote bone health. Additionally, three-fourths of 86 observational studies were also positive, indicating that the causal link established in investigator-controlled trials can be found in free-living subjects as well. The principal reason for failure to find an association in observational studies is the weakness of the methods available for estimating long-term calcium intake. While most of the investigator-controlled studies used calcium supplements, six used dairy sources of calcium; all were positive. Most of the observational studies were based on dairy calcium also, since at the time the studies were done, higher calcium intakes meant higher dairy intakes. All studies evaluating the issue reported substantial augmentation of the osteoprotective effect of estrogen by high calcium intakes. Discussion is provided in regard to the multifactorial complexity of osteoporotic response to interventions and to the perturbing effect in controlled trials of the bone remodeling transient, as well as about how inferences can validly be drawn from the various study types represented in this compilation.

Abstract
Women are disproportionately disabled by musculoskeletal conditions. For biologic and lifestyle reasons, musculoskeletal health is one of the areas of medicine in which the differences between men and women are most marked. Thus, an approach tailored to women, not just an approach based on what has worked for men, often is needed. How orthopaedists treat women will become an even more pressing issue in the years ahead. Demographic trends predict that the majority of senior citizens will be women in whom chronic conditions frequently involve a musculoskeletal problem. Even at earlier ages, women will present more frequently with musculoskeletal conditions because they participate in a broader range of sports and careers. The current study presents a lengthy list of action items that the orthopaedic surgeon should consider as he or she approaches the treatment of women. Many of these items involve anticipating musculoskeletal problems, and convincing patients to take appropriate preventive steps. Because so many patients are treated by physicians who are not orthopaedists for their musculoskeletal problems, a successful preventive approach presents orthopaedists with the opportunity to win the confidence and respect of a new generation of patients.

Abstract
Our objective was to describe the interventions aimed at preventing a recurrent hip fracture, and other injurious falls, which were provided during hospitalization for a first hip fracture and during the two following years. A secondary objective was to study some potential determinants of these preventive interventions. The design of the study was an observational, two-year follow-up of patients hospitalized for a first hip fracture at the University Hospital of Lausanne, Switzerland. The participants were 163 patients (median age 82 years, 83% women) hospitalized in 1991 for a first hip fracture, among 263 consecutively admitted patients (84 did not meet inclusion criteria, e.g., age>50, no cancer, no high energy trauma, and 16 refused to participate). Preventive interventions included: medical investigations performed during the first hospitalization and aimed at revealing modifiable pathologies that raise the risk of injurious falls; use of medications acting on the risk of falls and fractures; preventive recommendations given by medical staff; suppression of environmental hazards; and use of home assistance services. The information was obtained from a baseline questionnaire, the medical record filled during the index hospitalization, and an interview conducted 2 years after the fracture. Potential predictors of the use of preventive interventions were: age; gender; destination after discharge from hospital; comorbidity; cognitive functioning; and activities of daily living. Bi- and multivariate associations between the preventive interventions and the potential predictors were measured. In hospital investigations to rule out medical pathologies raising the risk of fracture were performed in only 20 patients (12%). Drugs raising the risk of falls were reduced in only 17 patients (16%). Preventive procedures not requiring active collaboration by the patient (e.g., modifications of the environment) were applied in 68 patients (42%), and home assistance was provided to 67 patients (85% of the patients living at home). Bivariate analyses indicated that prevention was less often provided to patients in poor general conditions, but no ascertainment of this association was found in multivariate analyses. In conclusion, this study indicates that, in the study setting, measures aimed at preventing recurrent falls and injuries were rarely provided to patients hospitalized for a first hip fracture at the time of the study. Tertiary prevention could be improved if a comprehensive geriatric assessment were systematically provided to the elderly patient hospitalized for a first hip fracture, and passive preventive measures implemented.

Abstract
OBJECTIVE Irritable bowel syndrome (IBS) is diagnosed by the presence of a constellation of symptoms fulfilling the Manning or Rome Criteria, after exclusion of organic disease. To exclude other diagnoses that might contribute to the abdominal pain or bowel symptoms experienced by subjects with IBS, numerous screening algorithms have been advocated, incorporating lactose hydrogen breath tests, thyroid function tests, fecal ova and parasite determination, and colonic endoscopy/radiography. The utility of these tests in uncovering alternative diagnoses, other than IBS, was examined in 1452 patients. METHODS Data were combined from two large multinational studies of IBS patients. All patients exhibited symptoms meeting the Rome criteria for IBS for at least 6 months before study entry. If prior evaluation had been > 2 yr previously, patients underwent colonic endoscopy/radiography at study entry. In addition, thyroid function tests, fecal ova and parasite determination, and a lactose hydrogen breath test were performed. RESULTS Lactose malabsorption was diagnosed in 23% (256/1122) of patients. Colonic abnormalities were detected in 2% (7/306) of patients; in four patients, colonic inflammation (n = 3) or obstruction (n = 1) may have contributed to symptoms of abdominal pain or altered bowel habits. Abnormal thyroid-stimulating hormone levels were detected in 6% (67/1209) of patients, of whom half were hypothyroid and half were hyperthyroid. Positive fecal ova and parasite tests were noted in 2% (19/1154) of patients. CONCLUSIONS Examination of screening tests in 1452 patients with an established history of IBS revealed an incidence of lactose malabsorption comparable to that in the general U.S. population and a low incidence of thyroid dysfunction, ova and parasite infestation, or colonic pathology. The limited detection rates, added costs, and inconvenience of these tests suggest that their routine use in the diagnostic evaluation of established IBS patients should be scrutinized.
