A cross-sectional analysis of the PURE study on minerals intake among Malaysian adult population with hypertension

Hypertension (HPT) is the leading modifiable risk factor for cardiovascular diseases and premature death worldwide. Currently, attention is given to various dietary approaches with a special focus on the role of micronutrient intake in the regulation of blood pressure. This study aims to measure the dietary intake of selected minerals among Malaysian adults and its association with HPT. This cross-sectional study involved 10,031 participants from the Prospective Urban and Rural Epidemiological study conducted in Malaysia. Participants were grouped into HPT if they reported having been diagnosed with high blood pressure [average systolic blood pressure (SBP)/average diastolic blood pressure (DBP) ≥ 140/90 mm Hg]. A validated food frequency questionnaire (FFQ) was used to measure participants' habitual dietary intake. The dietary mineral intake of calcium, copper, iron, magnesium, manganese, phosphorus, potassium, sodium, and zinc was measured. The chi-square test was used to assess differences in socio-demographic factors between HPT and non-HPT groups, while the Mann–Whitney U test was used to assess differences in dietary mineral intake between the groups. The participants’ average dietary intake of calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, sodium, and zinc was 591.0 mg/day, 3.8 mg/day, 27.1 mg/day, 32.4 mg/day, 0.4 mg/day, 1431.1 mg/day, 2.3 g/day, 27.1 µg/day, 4526.7 mg/day and 1.5 mg/day, respectively. The intake was significantly lower among those with HPT than those without HPT except for calcium and manganese. Continuous education and intervention should be focused on decreasing sodium intake and increasing potassium, magnesium, manganese, zinc, and calcium intake for the general Malaysian population, particularly for the HPT patients.

Development and validation of an eight-item calcium screener to assess daily calcium intake of patients with osteoporosis in clinical practice.

To validate a short food frequency questionnaire (screener) estimating daily average calcium intake from dietary sources to guide calcium supplementation of patients with osteoporosis in clinical practice. An eight-item calcium screener was developed based on existing literature, food consumption data and expert opinion. Convergent validity was determined by comparison with 3-day food records using mean difference, Spearman's correlation coefficients (SCC) and Bland-Altman analysis. Test-retest reliability was assessed by SCC and intraclass correlation coefficients (ICC). We calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) to identify patients requiring calcium supplementation (<1200 mg dietary calcium intake/day). Fifty-two patients filled out the eight-item calcium screener and the 3-day Food record (mean age of 66.8 ± 12.9 (SD)) and 38 patients filled out the screener twice for reliability analysis (mean age of 65.8 ± 12.8 (SD)). Dietary calcium intake between the calcium screener and food records showed a strong correlation (N = 52 patients, SCC = 0.53, p ≤ 0.001) and mean difference of 21 mg (p = 0.70). Bland-Altman analysis showed agreement within 95% confidence intervals for 49/52 comparisons (94%). Test-retest reliability of the calcium screener was excellent (SCC = 0.96, p ≤ 0.001; ICC = 0.99, p ≤ 0.001). The calcium screener shows good convergent validity, reliability and feasibility to estimate daily calcium intake of patients with osteoporosis in routine clinical practice.

Vitamin D status in non-pregnant women of reproductive age: a study in Southern Thailand

Vitamin D inadequacy is a global problem in all age groups. Although there are various studies of vitamin D status in pregnant women in Southeast Asia, to date there are few studies from Southeast Asia examining vitamin D status in non-pregnant women of reproductive age. To examine the prevalence of vitamin D insufficiency (VDI) in healthy non-pregnant women of reproductive age in Southern Thailand, 120 healthy non-pregnant women aged 18–42 years were enrolled. Demographic and lifestyle data relevant to vitamin D assessment (sunlight exposure, nutritional intake, type of dress, sunscreen use) and biochemical studies (serum 25-hydroxyvitamin D or 25OHD, parathyroid hormone, calcium, phosphate) were obtained. VDI was classified as serum 25OHD < 20 ng/mL. The average serum 25OHD level was 23.1 ± 6.0 ng/mL. The overall prevalence of VDI was 34.1%. The average dietary intake of calcium, phosphorus and vitamin D and the average duration of sunlight exposure per week were not significantly different between the VDI women and the vitamin D sufficient (VDS) women. Logistic regression analysis found that the significant risk factors for VDI were greater body mass index and higher family income (p-values 0.01 and 0.02, respectively). The prevalence of VDI in non-pregnant women was high at 34%. As the dietary sources of vitamin D are limited and cutaneous vitamin D synthesis is limited by avoidance of sunlight exposure, vitamin D fortification in common daily foods would be an alternative option to reach the recommended vitamin D intake generally of at least 800 IU/day.

Structural changes and calcium bioaccessibility of calcium fortified milk containing CaCO3 loaded solid-in-oil-in-water emulsion during simulated in vitro digestion.

In most regions around the globe, average dietary calcium intake is relatively low. Consumers increasingly supplement calcium with milk. However, commercial high-calcium milk has the problem of low calcium bioaccessibility. This study was to explore calcium fortified milk containing calcium carbonate (CaCO3 ) loaded solid-in-oil-in-water emulsion as a potential novel calcium fortified milk with higher calcium bioaccessibility. The CaCO3 loaded solid-in-oil-in-water (S/O/W) emulsion with good physical stability (zeta potential -33.34 ± 0.96 mV, mean particle size 4.49 ± 0.02 μm) and high calcium bioaccessibility (32.34%) was prepared when the concentration of xanthan gum was 4 g L-1 . Furthermore, the physicochemical properties and gastrointestinal fate of calcium fortified milk (calcium contents, 1.25 mg mL-1 , 1.35 mg mL-1 , and 1.45 mg mL-1 ) with different proportions of CaCO3 loaded S/O/W emulsion and pure milk were investigated. The calcium fortified milk (calcium content, 1.25 mg mL-1 ) with a small amount of CaCO3 loaded S/O/W emulsion did not significantly affect the physicochemical properties of pure milk and had similar rheological properties and higher calcium bioaccessibility to commercial high-calcium milk. Excessive calcium ion (Ca2+ ) weakens the electrostatic interaction of milk sample system and causes aggregation of colloidal particles, which was attributed to more insoluble calcium soap formation. This study showed that the S/O/W emulsion delivery system improved the dispersion stability and bioaccessibility of CaCO3 . These findings contribute to the development of calcium fortified milk with improved physicochemical properties and higher calcium bioaccessibility. © 2023 Society of Chemical Industry.

The association of long-term calcium and dairy products intake in adolescence with carotid intima media thickness and metabolic syndrome in early adulthood: Tehran Lipid and Glucose Study

BackgroundCalcium could impact on vascular functions and structures and cause atherosclerosis. Thus, we aimed to examine the association of long-term calcium and dairy products intake in adolescence with cIMT and MetS in early adulthood.MethodsWe considered 217 adolescents aged 12–18 years in the frame work of the Tehran Lipid and Glucose Study (2006–2009) and follow-up them to early adulthood (2015–2017). The valid food frequency questionnaire was used to assess dietary intake. Ultrasound examination was used to measure common carotid artery. The joint interim statement and cook et al. criteria were used for adults and adolescents to consider MetS, respectively.ResultsAdolescents’ average calcium intake from dairy and non-dairy sources were 395 mg/d and 1088 mg/d, respectively while adults had 212 mg/d and 1191 mg/d. In addition, the mean of cIMT in adults was 0.54 mm. There was no relationship of non-dairy (β: − 0.03; P = 0.804), and total calcium (β: − 0.001; P = 0.591) intake with cIMT and TG. None of the dairy products had link with cIMT, MetS and its components, except cream with cIMT after full adjustment of potential confounders (β: 0.245; P = 0.009). Also, we found that the intake of non-dairy products could increase DBP after controlling for potential confounders (β: 0.365; P = 0.012). Adolescence with higher quartiles of total calcium intake had no odds ratio of MetS in early adulthood (β: 2.05, P = 0.371).ConclusionsAdolescence calcium and dairy products intake, with the exception of cream did not increase early adulthood cIMT and MetS and its components.

Determination of Nutrient Intake and Dietary Antioxidant Capacity in Autism Spectrum Disorder: A Case-Control Study.

The aim of this study was to evaluate the nutrient intake and dietary antioxidant capacity of children and adolescents with ASD. The study included 38 children and adolescents with ASD aged 6-18years and 38 gender and age-matched peers without ASD. Caregivers of participants who met inclusion criteria completed a questionnaire form, three-day food consumption record and antioxidant nutrient questionnaire. There were 26 (68.4%) boys and 12 (31.6%) girls in both groups and mean age of participants with and without ASD was 10.9 ± 4.03years versus 11.1 ± 4.09years, respectively. The average intake of carbohydrates, vitamin D, calcium, sodium and selenium was lower in participants with ASD than in participants without ASD (p < 0.05). In both groups, dietary fiber, vitamin D, potassium, calcium and selenium intake insufficiency were high, and there was a significant difference between the two groups in terms of carbohydrate, omega 3, vitamin D and sodium intake insufficiency. Considering the antioxidant intakes of the participants, the median value of dietary antioxidant capacity from food consumption record of participants with and without ASD was 3.2 (1.9) mmol versus 4.3 (1.9) mmol, respectively, whereas the dietary antioxidant capacity from antioxidant nutrient questionnaire was 3.5 (2.9) mmol versus 4.8 (2.7) mmol, respectively (p < 0.05). It is predicted that providing nutritional counseling and regulation of diet, especially keeping the antioxidant capacity of diets high, may be effective in reducing some of the symptoms of ASD.

Hubungan Asupan Kalsium dan Indeks Massa Tubuh dengan Kepadatan Tulang pada Wanita Usia Subur

In women of childbearing age, the rate of bone formation will decrease gradually. If a bone formation is reduced continuously then it can cause osteoporosis. Insufficient calcium intake and abnormal body mass index can also cause reduced bone density. The purpose of this study was to analyze the correlation between calcium intake and body mass index with bone density in women of childbearing age in the Medical Faculty Universitas Lampung in 2021. This cross-sectional study of 80 respondents consisting of lecturers, employees, and students aged 20-45 years who were selected by purposive sampling was carried out in November-December 2021. Demographic data, Semi Qualitative-Food Frequency Questionnaire (SQ-FFQ), Kris digital scales 9360A, microtoise GEA, and Quantitative Ultrasound (QUS) were used to measure all variables. Spearmen Correlation Test with a significant level of p-value&lt;0.05 was used to see the relationship between variables. The results of the univariate analysis showed that the majority of respondents were aged 20-25 years (76.2%) and college students (78.8%). The average intake of calcium and body mass index was 709.2 and 21.2 and 31 respondents (38.8%) had osteoporosis. The results of the bivariate analysis showed a positive and significant correlation between calcium intake and bone density (p-value=0.000, r=0.687) and bone body mass index with bone density (p-value=0.000, r=0.596). The conclusion, there was a positive and significant correlation between calcium intake and body mass index with bone density in women of childbearing age in the Medical Faculty of Universitas Lampung in 2021.

The Role of Calcium in the Skin Barrier

Calcium is a macro mineral that is an important part of the body. Bones and teeth contain more than 99% of the human body calcium. Calcium also found in other tissues such as skin. The concentration of calcium in the body tends to decrease with age because released from the body through sweat, skin cells, and faeces. Calcium intake varies worldwide with an average of 175-1233 mg/day. Many countries in Asia have an average calcium intake of less than 500 mg/day. The skin barrier function is in the epidermis, the formation of the epidermal barrier and the maintenance of homeostasis are important to protect the individual from the external environment and organisms. Epidermal calcium gradient, endoplasmic reticulum (ER) calcium homeostasis, and calcium influx through calcium channels play important roles in keratinocyte differentiation, barrier formation, and barrier homeostasis. Understanding the mechanism of regulation and function of calcium related to skin barrier homeostasis is aimed to improve understanding of calcium in the skin barrier

Nutrient Consumption among the Bangladeshi Children with Autism

Background: The prevalence of Autism in South Asia is 1 in 93 children, where, prevalence is much higher, 3% in Dhaka city of Bangladesh. Consumption of daily required nutrient is essential for these children like normal ones but sometimes may be neglected. Objectives: This study was undertaken to assess the macro and micronutrient consumption among the children with autism in Dhaka city and compared to the requirement.Material &amp; Methods:In this cross-sectional study, 100 subjects where male-female ratio was 3:2, were studied from urban autism centers Dhaka, Bangladesh. Anthropometric parameters height, weight, BMI and 24-hour dietary recall (individual 3days) were collected following predesigned questionnaire. Data was collected from face to face interview from both parents and center’s teacher as appropriate. Nutritive value of food was calculated using Food Composition Table for Bangladesh, 2014 using a food software. For statistical analysis, SPSS 20 was used.Results:The average age and BMI of subjects were 11 yrs and 21 kg/m2 respectively. The mean ±SDvalues (g/day) of protein, fat and carbohydrate intake were 38±15, 47±12 and 116±38 respectively. The average intake of (mg/day) thiamine, riboflavin, vitamin C, calcium, magnesium, iron, niacin, and zinc was 0.68±0.32, 0.46±0.23, 33±24, 144±87, 137±55, 6.5±2, 11±4 and 5.2±2 respectively. About 94% children consumed only 33% of the required calcium. Nearly 42% children took 67% of the required magnesium. Similarly, half of the children failed to consume 33% thiamine and zinc of the requirement. Conclusions:Consumption of calcium, thiamine, folic acid, and zinc are seemed to be lower than their requirement.

Decomposition of Socioeconomic Changes in the Consumption of Micronutrients in Pakistan between 2006 and 2016

ABSTRACT This study is conducted to decompose inequality in four important micronutrient intakes, i.e. calcium, iodine, iron, and zinc due to socioeconomic factors during 2006–2016. For this purpose, data were taken from national-level surveys, i.e. HIES-2006 and HIICS-2016. We applied a recently proposed decomposition method based on copula function to decompose between year changes in the consumption of micronutrients into structure and composition effect. The results show that average calcium and iron intakes increased by 518.54 (mg) and 0.962 (mg), respectively, while average iodine and zinc intakes decreased by 2.009 (mg) and 3.411 (mg), respectively, during the decade. Estimates of structure effect show that calcium, iodine, and iron consumption increased on average, i.e. 525.316 (mg), 14.615 (mg), and 2.15 (mg), respectively, while zinc intake decreased by 2.735 (mg). The composition effect is negative for all the four micronutrients, implying that consumption of calcium, iodine, iron, and zinc decreased as 6.7766 (mg), 16.624 (mg), 1.189 (mg), and 0.677 (mg), respectively. The main factors of this change are household income, urbanization, provinces, and household size. The policymakers need to know the importance of socioeconomic factors to improve hidden hunger in terms of micronutrient intakes.

Nutrition assistance for pregnant women with chronic energy deficiency and anemia to increase nutritional intakeBackground: Nutrition assistance for pregnant women with chronic energy deficiency (CED) with family or community empowerment strategies and community participation is necessary to improve the nutritional status of pregnant women and babies during the 1000 first days of life.Objective: This study aims to determine the effect of assisting pregnant women with CED on changes in nutrition intake in Bengkulu and Bandar Lampung City.Methods: The research design used a quasi-experimental design with a non-randomized control group pre and post-test design. The research was conducted in Bengkulu and Bandar Lampung city. A sample of 120 pregnant women with CED and anemia, consisting of 60 intervention groups and 60 control groups selected by purposive sampling. The intervention group received assistance from pregnant women by health cadres using nutrition education media from the second trimester of pregnancy to the mother before delivery for 3 months. Cadres carry out health promotion, monitor the nutritional status of pregnant women, and assist in supplementary feeding of pregnant women and Fe tablets. The control group received standard services from the puskesmas/posyandu without assistance from cadres. Nutrition intake includes intake of carbohydrates, protein, fat, iron, and calcium. Changes in nutritional intake before and after training were analyzed using a statistical paired t-test. Differences in nutritional intake between the intervention and control groups using independent t-test.Results: Nutrition assistance for pregnant women with CED and anemia was effective in improving the intake of carbohydrates, protein, fat, Fe, and calcium. There was an increase in the average intake of carbohydrates, protein, fat, Fe, and calcium in Bengkulu and Bandar Lampung City.Conclusions: Nutrition assistance for pregnant women with CED and anemia is effective in increasing nutrition intake.

Effects of different calcium intakes on metabolism in healthy adults under strict dietary intervention

Objective: To explore the effect of different calcium intakes on metabolism in healthy adults with traditional Chinese dietary pattern. Methods: A total of 64 college students (32 males and 32 females) were recruited from the School of Public Health, Harbin Medical University from September to October 2015. A prospective, randomized, double-blind, placebo-controlled trial design (RCT trial) was used to strictly control the diet of the volunteers through meal preparation, so that the background of the experimental and the control group was exactly the same. In our study, 64 healthy adults were randomly divided into two groups (calcium supplementation and control). The two groups were given the same diet every day. One group was given 400 mg/d of calcium supplementation, which was close to the recommended intake in China (800 mg/d); the other group was given pacebo, the average calcium intake was close to the average intake of Chinese (400 mg/d), calcium intervention lasted for 35 days. Serum and urine samples from pre-intervention, mid-intervention, and post-intervention were collected for metabolomics studies and detection of serum hormone levels and biochemical indicators. PCA and PLS-DA were used to compare the differences in serum and urine metabolites. After adjusting for age and BMI, the differences of hormones [parathyroid hormone, 1, 25(OH)2D3] and biochemical indicators were compared by repeated measurement variance analysis. Results: The 64 subjects were aged 23-28 years, including 32 males and 32 females. The baseline characteristics of the calcium supplementation group and the control group were balanced. The results showed that there were no significant differences in blood and urine metabolites, metabolic hormone [parathyroid hormone, 1, 25(OH)2D3] levels and biochemical indicators(serum Ca, serum P, glycolipid metabolism and hepatorenal function indicators)between the calcium supplementation group and control group at each time point throughout the trail (P>0.05). Conclusion: No health hazards associated with calcium deficiency was observed in healthy adults in the short term at current calcium intake level (300-400 mg/d).

Estimated average calcium – magnesium content in day meal in a sample of students from Faculty of Medicine of Sarajevo University

Nutrients are chemical substances obtained from food. They have different roles in body. Some are used as energy source, some as structural materials, and regulating agents. Nutrients may reduce the risks of some diseases. There are some recommendations about dietary intake of these nutrients for optimal health. This study aimed to estimate average calcium and magnesium content in day meal in a sample of students from Faculty of Medicine of Sarajevo University. A cross-sectional study was conducted during academic 2015/16 year at Faculty of Medicine of Sarajevo University. The survey covered 44 students. The research instrument was a self-administered questionnaire, by which 3-Day Diet Record was provided. The average intakes of calcium and magnesium were estimated using Nutritional analysis computer program (Nutrics Professional Nutrition Analysis Software). On daily level average intake of calcium was 718.39±311.14 mg in total sample and average intake of magnesium was 292.57±310.10 mg in total sample. Average Ca/Mg ratio was 2.45. In our sample cheese was top source of calcium with Ca/Mg ratio of 32.5, and bread was top source of magnesium with Ca/Mg ratio of 3.1. These results emphasize the importance of monitoring the food nutrition facts in order to achieve adequate nutrients intake.

This study aims to analyze the pattern of consumption and environmental sanitation in stunting children in the Wonomulyo Polewali Mandar district. Method The study design used was analytic observational. The total sample was 101 toddlers aged 6-36 months, using simple random sampling method. The determination of nutritional status was processed using the WHO AntroPlus 2010 including the Semi Quantitative Food Frequency Questionnaire and an environmental sanitation questionnaire.&#x0D; Results: The frequency of frequent consumption of carbohydrates 79.21%, the frequency of animal protein (48.52%), vegetable protein (41.58%), fruit (46.58%), and beverages (43.6%). ), snacks (47.52%), and rare frequency of vegetables (44.54%). The average intake of energy (773.87 kcal), protein (18.19 gr), calcium (471.61 mg), and iron (8.15 mg). There was no significant relationship with the adequacy of nutrients for energy (p = 0.422), protein (p = 0.428), calcium (p = 0.075) and iron parameters had a significant relationship (p = 0.049). The results of environmental quality measurement obtained data on toddlers with short and very short nutritional status in the healthy environmental sanitation category as much as 18 (17.8%) and toddlers with short and very short nutritional status in the category of unhealthy environmental sanitation by 83 (82.2%). So that the results of the sig value test (2-sided) of 0.951&gt; 0.05, it can be concluded that there is no relationship between nutritional status and unhealthy sanitary conditions. Conclusion: Iron adequacy is related to stunting status, while environmental sanitation quality is not related to stunting status.

Nutritional status of Moroccan pregnant women and the birth weight of their newborn: a case-control study in the province of El Jadida

&lt;abstract&gt;&lt;sec&gt; &lt;title&gt;Background&lt;/title&gt; &lt;p&gt;Maternal malnutrition is a global concern whose consequences for newborns are intrauterine growth retardation, fetal hypotrophy and exposure to risks of pathologies in adulthood.&lt;/p&gt; &lt;/sec&gt;&lt;sec&gt; &lt;title&gt;Objective&lt;/title&gt; &lt;p&gt;The aim of this study was to assess and compare the diet quality and nutritional status of pregnant women at the time of childbirth while assessing their newborn's weight at birth.&lt;/p&gt; &lt;/sec&gt;&lt;sec&gt; &lt;title&gt;Materials and methods&lt;/title&gt; &lt;p&gt;The study involved 400 parturient, divided into two groups of 200 each, the controls who have just given birth to newborns of normal weight and the cases who have just given birth to babies of low birth weight (LBW). Information on food intakes and dietary habits were collected using questionnaires and anthropometric parameters were measured.&lt;/p&gt; &lt;/sec&gt;&lt;sec&gt; &lt;title&gt;Results&lt;/title&gt; &lt;p&gt;The mean body mass index (BMI) of the cases was 25.93 ± 2.64 kg/m&lt;sup&gt;2&lt;/sup&gt; vs. 28.25 ± 2.75 kg/m&lt;sup&gt;2&lt;/sup&gt; in the controls. The dietary diversity and variety scores were higher in the controls than in the cases. Indeed means were 6.87 ± 1.30 vs. 8.88 ± 1.35 food groups for the diversity scores and 11.77 ± 1.57 vs. 15.90 ± 2.09 food items for the variety scores in the cases and the controls respectively. The average daily intakes of folates, calcium, iron and zinc were lower than the Recommended Daily Allowances (RDA) for both groups. The daily calcium intake represents only 1/5th of the RDI for the cases and 1/3 for the controls. Average dietary iron intake was insufficient at only 49% of the daily requirement for cases vs. 66.88% for controls while folates accounts for 64.33% of the RDA for the cases.&lt;/p&gt; &lt;/sec&gt;&lt;sec&gt; &lt;title&gt;Conclusion&lt;/title&gt; &lt;p&gt;Data from this study shows that the diets of women who have given birth to low birth weight infants are poorly diversified, poorly varied, and poor in certain nutrients essential for a successful pregnancy and childbirth.&lt;/p&gt; &lt;/sec&gt;&lt;/abstract&gt;

The Contribution of Patient, Primary Care Physician, and Primary Care Clinic Factors to Good Bone Health Care.

Patient, provider, and system factors can contribute to chronic care management and outcomes. Few studies have examined these multilevel associations with osteoporosis care and outcomes. We examined how key process and structural factors at the patient, primary care physician (PCP), and primary care clinic (PCC) levels were associated with guideline concordant osteoporosis pharmacotherapy, daily calcium intake, vitamin D supplementation, and weekly exercise sessions at 52 weeks following enrollment in a cluster randomized controlled trial. We conducted a secondary analysis of observational data from 1 site of the trial. The study sample included 1996 men and women ≥ 50 years of age at the time of recruitment following completion of a dual-energy x-ray absorptiometry (DXA) scan and who had complete data at baseline and 52 weeks. Our primary independent variable was "relationship continuity": the DXA-ordering provider was the patient's PCP. Hierarchical linear and logistic regression accounted for patient, provider, and primary care clinic characteristics. In multivariable regression analyses, relationship continuity (ie, the PCP ordered the study DXA) was associated with higher average daily calcium intake and likelihood of vitamin D supplementation at 52 weeks. No PCP or primary care clinic factors were associated with osteoporosis care. The relationship continuity, in which the provider ordering a DXA is the patient's PCP and therefore also presents the results of a DXA, may help to promote patient behaviors associated with good bone health.

Calcium intake, calcium supplementation and cardiovascular disease and mortality in the British population: EPIC-norfolk prospective cohort study and meta-analysis

The role of dietary calcium in cardiovascular disease prevention is unclear. We aimed to determine the association between calcium intake and incident cardiovascular disease and mortality. Data were extracted from the European Prospective Investigation of Cancer, Norfolk (EPIC-Norfolk). Multivariable Cox regressions analysed associations between calcium intake (dietary and supplemental) and cardiovascular disease (myocardial infarction, stroke, heart failure, aortic stenosis, peripheral vascular disease) and mortality (cardiovascular and all-cause). The results of this study were pooled with those from published prospective cohort studies in a meta-analsyis, stratifying by average calcium intake using a 700 mg/day threshold. A total of 17,968 participants aged 40–79 years were followed up for a median of 20.36 years (20.32–20.38). Compared to the first quintile of calcium intake (< 770 mg/day), intakes between 771 and 926 mg/day (second quintile) and 1074–1254 mg/day (fourth quintile) were associated with reduced all-cause mortality (HR 0.91 (0.83–0.99) and 0.85 (0.77–0.93), respectively) and cardiovascular mortality [HR 0.95 (0.87–1.04) and 0.93 (0.83-1.04)]. Compared to the first quintile of calcium intake, second, third, fourth, but not fifth quintiles were associated with fewer incident strokes: respective HR 0.84 (0.72–0.97), 0.83 (0.71–0.97), 0.78 (0.66–0.92) and 0.95 (0.78–1.15). The meta-analysis results suggest that high levels of calcium intake were associated with decreased all-cause mortality, but not cardiovascular mortality, regardless of average calcium intake. Calcium supplementation was associated with cardiovascular and all-cause mortality amongst women, but not men. Moderate dietary calcium intake may protect against cardiovascular and all-cause mortality and incident stroke. Calcium supplementation may reduce mortality in women.

Bone mineral density and nourishment

Some diet pattern is connected with higher risk of obesity and deficit of different nutrients. Both can contribute to complications of chronic disease like osteoporosis. The primary objective of this study was to analyze the correlation between bone mineral density and body mass, i.e. nutrients intake. The cross-sectional study included 25 patients who had regular osteodensitometrycal checkup. Patients anthropometrics' characteristics were collected by interview. Dietary pattern was estimated through food-frequency questionnaire and average meal was made. Nutritional analysis computer program (Nutrics Professional Nutrition Analysis Software) was used to analyze the average intake of nutrients from the food intake data. The average T score of hip was at level of osteopenia (-1.7), and BMI was 25.80 kg/m2. By comparing the results using Pearson coefficient, we found positive linear trend and statistical significance at p &lt;0.05. The average T score of lumbar spine was at level of osteoporosis (-2,19), and average intake of calcium was 1519 mg. By comparing the results using Pearson coefficient, we found negative linear trend and statistical significance at p &lt;0.05. These data indicate that BMI and nutrients intake are connected with the risk for osteoporosis. There is the need for osteoporosis prevention strategies based on nutrition recommendations.

An analysis of policy interventions regarding school lunch programs and their role in the healthy nutrition of children in Córdoba, Argentina

The aim of this article is to analyze school lunch programs and their role in the healthy nutrition of children in Córdoba, Argentina from 2013 to 2018. A descriptive, cross-sectional study was conducted that included a sample of 10 schools in 2013 and 10 different schools in 2018. A survey of school lunch programs and 24-hour nutrition reminders was carried out with 341 children. The nutritional value of school lunch programs decreased over the study period, particularly among schools in contexts of greater social vulnerability. Significant reductions in average calcium and energy intake were also observed. Indicators of chronic malnutrition, overweight, and excess calcium and vitamin A and C intakes worsened among children attending school lunch programs. Regarding the association between school lunch program attendance and low height for age/risk of low height for age, the odds ratio was not statistically significant. We argue for the necessity of promoting policies that seek urgent improvements in child nutritional indicators from a rights-based perspective.

Assessment of calcium intake and perception of calcium-rich food among healthcare students at King Saud bin Abdulaziz University for Health Science (KSAU-HS).

Calcium is an essential mineral compound and one of the most abundant minerals in the human body. A long-term low calcium intake predisposes the bones to fractures, osteopenia, and osteoporosis. This study was conducted to assess calcium intake and knowledge of calcium-related information among healthcare students in King Saud bin Abdulaziz University for Health Sciences (KSAU-Hs). This cross-sectional survey was conducted using a self-administered questionnaire that has been distributed as a soft copy of 289 participants aged 19years or older and studied at KSAU-Hs. The questionnaire had three sections assessing demographical data, calcium knowledge, and calcium intake.
