“…However, since dietary guidelines aim to promote overall healthy ageing by preventing all chronic diseases such as cardiometabolic diseases and cancer, our BMD-Diet Score should be studied in relation to these health outcomes as well. Calcium might favor BMD while adversely affecting cardiovascular disease risk [ 39 ], whereas an approach which evaluates the full diet, such as the BMD-Diet Score, might indicate benefit for various aspects of healthy ageing simultaneously.…”

Development of a Food Group-Based Diet Score and Its Association with Bone Mineral Density in the Elderly: The Rotterdam Study

No diet score exists that summarizes the features of a diet that is optimal for bone mineral density (BMD) in the elderly. Our aims were (a) to develop a BMD-Diet Score reflecting a diet that may be beneficial for BMD based on the existing literature, and (b) to examine the association of the BMD-Diet Score and the Healthy Diet Indicator, a score based on guidelines of the World Health Organization, with BMD in Dutch elderly participating in a prospective cohort study, the Rotterdam Study (n = 5144). Baseline dietary intake, assessed using a food frequency questionnaire, was categorized into food groups. Food groups that were consistently associated with BMD in the literature were included in the BMD-Diet Score. BMD was measured repeatedly and was assessed using dual energy X-ray absorptiometry. The BMD-Diet Score considered intake of vegetables, fruits, fish, whole grains, legumes/beans and dairy products as “high-BMD” components and meat and confectionary as “low-BMD” components. After adjustment, the BMD-Diet Score was positively associated with BMD (β (95% confidence interval) = 0.009 (0.005, 0.012) g/cm2 per standard deviation). This effect size was approximately three times as large as has been observed for the Healthy Diet Indicator. The food groups included in our BMD-Diet Score could be considered in the development of future dietary guidelines for healthy ageing.

“…32 Finally, the third mechanism is associated with the fact that calcium absorption is inefficient; thus, a large proportion of calcium remains in the intestine where it can bind to bile acids or to fatty acids impairing their absorption and decreasing available energy. [33][34][35][36][37][38][39] A systematic review including 6 studies from the United States and 1 from Iran with a total of 794 women showed that in obese adults, mainly nonpregnant women, calcium supplementation from 6 to 12 months compared to placebo had a greater effect to reduce body weight (0.74 kg; 95% CI: 1.00-0.48). These results are similar to the weight difference found in the obese subgroup of our study.…”

The Effect of Calcium Supplementation on Body Weight Before and During Pregnancy in Women Enrolled in the WHO Calcium and Preeclampsia Trial

Introduction: Obesity is a major and challenging public health problem. The aim of this substudy is to evaluate the effect of calcium supplementation on body weight in women recruited in the Calcium and Preeclampsia trial. Methods: Women were recruited before pregnancy and randomized to receive a calcium supplement containing 500 mg of elemental calcium or placebo until 20 weeks’ gestation; all women received 1.5 g from 20 weeks until delivery. Results: A total of 630 women conceived during the study, 322 allocated to calcium and 308 to placebo. Among these, 230 allocated to calcium and 227 allocated to placebo had information on body weight at baseline and at 8 weeks' gestation. During the study period, women allocated to calcium had a mean weight increase of 1.1 (SD ±5.5) kg, whereas those allocated to placebo had a mean increase of 1.5 (SD ±6.1) kg, a mean difference of 0.4 kg (95% −0.4 (−1.4 to 0.6); P = .408). Women classified as obese at the start of the trial had a lower body weight gain at 8 weeks’ gestation (1.0 kg; 95% CI: −3.2 to 1.2; P = .330) and at 32 weeks’ gestation (2.1 kg; 95% CI: 5.6-1.3; P = .225) if they received calcium as compared to placebo. However, none of these differences were statistically significant. Conclusion: The smaller increase in body weight found in women supplemented with 500 mg elemental calcium daily is quantitatively consistent with previous studies. However, in this study, the difference was not statistically significant.

“…In fact, it is more desirable for patients to obtain their calcium through diet than through supplementation. 21 , 22 However, relatively few hip fracture patients have adequate dietary calcium intake and therefore need supplementation. Health Canada reports that elderly men older than 70 years are getting 69% less calcium than the current recommendation and elderly women are getting 63% less calcium than recommended.…”

Introduction:Introduction: Adequate calcium and vitamin D from diet and supplementation is recommended for elderly hip fracture patients. Using data from the multinational hip fracture arthroplasty trial (HEALTH), we determined the proportion of patients who consistently took vitamin D and calcium and which characteristics/prescribing practices were associated with consistency of supplement use.Methods:HEALTH is a multicenter randomized trial of elderly hip fracture patients treated with hemi-arthroplasty and total hip arthroplasty. Patients were categorized as consistent users, inconsistent users, or nonusers of calcium and vitamin D. We used multinomial regression to determine the characteristics associated with calcium and vitamin D use.Results:603 HEALTH participants were included in the analysis. 34.7% of patients never took vitamin D within 12 months after surgery, 26.2% took vitamin D inconsistently, and 39.1% took vitamin D consistently. 36.0% of patients never took calcium within 12 months after surgery, 28.4% took calcium inconsistently, and 35.7% took calcium consistently. There was great variation in prescribed/recommended doses. Compared to nonusers, consistent users of the supplements were more likely to be female, North American, prescribed/recommended vitamin D and/or calcium postoperatively, and presented to a facility with comprehensive fragility fracture protocols.Conclusions:A low proportion of elderly hip fracture patients are consistently taking vitamin D and calcium, which may contribute to poorer bone health. Surgeons should be educated to prescribe/ recommend vitamin D and calcium, institutions should develop comprehensive fragility fracture protocols and patient education strategies to ensure that patients with osteoporosis receive bone health management beyond fracture care.
