Dimas-Benedicto C, Albasanz JL, Bermejo LM, Castro-Vázquez L, Sánchez-Melgar A, Martín M, Martínez-García RM. Impact of Iron Intake and Reserves on Cognitive Function in Young University Students. Nutrients 2024; 16:2808. [PMID: 39203944 PMCID: PMC11356983 DOI: 10.3390/nu16162808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 08/19/2024] [Accepted: 08/20/2024] [Indexed: 09/03/2024] Open
Abstract
Iron is a key nutrient for cognitive function. During periods of high academic demand, brain and cognitive activity increase, potentially affecting iron intake and reserves. The present study aimed to investigate the impact of iron levels on cognitive function in a university sample, considering the influence of gender. A cross-sectional study was conducted with 132 university students (18-29 years) from the University of Castilla-La Mancha (Spain). A dietary record was formed through a questionnaire to analyze iron consumption, and blood and anthropometric parameters were measured. The Wechsler Adult Intelligence Scale-IV was used to determine the Intelligence Quotient (IQ), as well as the Verbal Comprehension Index (VCI), Working Memory Index (WMI), Processing Speed Index (PSI), and Perceptual Reasoning Index (PRI), to assess cognitive abilities. Among women, the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) was 21% and 4.2%, respectively. No ID or IDA was found in men. The impact of iron intake on IQ and cognitive abilities was mainly associated with the female population, where a positive association between iron intake, serum ferritin, and total IQ was revealed. In conclusion, low iron intake is related to poorer intellectual ability, suggesting that an iron-rich diet is necessary to maintain the academic level of university students.

Vitamin B12 status among asymptomatic young adult females and its association with some anthropometric and biochemical parameters: A cross-sectional study from Makkah (cobalamin deficiency in young adult females). Medicine (Baltimore) 2023; 102:e35838. [PMID: 37933046 PMCID: PMC10627631 DOI: 10.1097/md.0000000000035838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 10/06/2023] [Indexed: 11/08/2023] Open
Abstract
This study was designed to measure the prevalence of vitamin B12 deficiency among young adult females in Makkah City and study its correlation with some anthropometric and biochemical indicators. A cross-sectional study and a detailed questionnaire were used to collect information from 402 young women aged 19 to 22 years, who were university students. Moreover, dietary assessments using a validated food frequency questionnaire and anthropometric measurements were performed. The mean values of serum vitamin B12, serum folate, hemoglobin, and body mass index (BMI) were 343.29 ± 148.16 pg/mL, 12.72 ± 2.62 ng/mL, 12.69 ± 1.41 g/dL, and 22.64 ± 4.24 kg/m2, respectively. About three-quarters of the study sample had normal vitamin B12 levels, while the rest had vitamin B12 deficiency. Meanwhile, a significant negative association (r = -0.201, P = .048) was found between abdominal fat and serum vitamin B12 levels. This study concluded that the young adult females' population from Makkah City is among the risk groups for vitamin B12 deficiency, which is highly correlated with inappropriate values of weight, body fat, and some blood indices. Appropriate dietary interventions and awareness are needed for this population.

Abstract
OBJECTIVE To determine the association between dietary folate intake and low cognitive performance in older adults. METHODS In this cross-sectional observational study, 2011-2014 data from the 2010 National Health and Nutrition Examination Survey, including 2,524 adults aged 60 years and older, included 24-hour dietary intakes. Total folic acid intake was calculated as the sum of folic acid supplements and dietary folic acid. Cognitive function was assessed using three tests. The association between folate intake and cognitive function was assessed using a multivariate conditional logistic regression model. RESULTS 2524 participants from two survey cycles (2011-2014) in the NHANES aged 60 years and over. In the multivariate logistic regression, the OR of developing folate was 0.96 (95% CI: 0.94∼0.98) in participants with Z test. Folate intake was negatively associated with cognitive function. Compared with Q1, Q4(≥ 616.3mg/day) in the AFT and DSST tests reduced the risk of cognitive impairment by 31% (OR = 0.69, 95% CI: 0.52-0.93) and 44% (OR = 0.56). 95% confidence interval: 0.44-0.7). In the comprehensive evaluation of IR and AFT scores, the association between dietary folate intake and low cognitive performance in US adults is linear. We also found a significant interaction between gender and cognitive ability (P value for the interaction was 0.021). CONCLUSIONS Dietary intake of folic acid may be inversely associated with cognitive impairment. The DSST study found an L-shaped association between dietary folate intake and cognitive decline in US adults, with an inflection point of approximately 510,383 mg/day.

Abstract
Young adulthood is the period from the late teens through the twenties and is associated with life transitions that could contribute to the development of obesity. Targeting this group will be critical to reversing the obesity epidemic. The aim of the study was to investigate the eating behaviors and lifestyle of healthcare students in Poland. We enrolled 227 students in the study. Convenience sampling was employed. Diet (Food Frequency Questionnaire), physical activity (International Physical Activity Questionnaire), depressive symptoms (Beck Depression Inventory), impulsivity (Barratt Impulsivity Scale), and eating behaviors (Three-Factor Eating Questionnaire) were assessed. One in three students exhibited depressive symptoms, one in four showed low levels of physical activity. More than 40% of the students did not consume vegetables at least once a day, and more than half did not consume fruit. Only approximately 50% of the students ate fish several times a month. There was an association between high scores of specific eating behaviors and body weight, adherence to the Mediterranean diet, and consumption of specific product groups (sweets, alcohol). The results of our study are expected to contribute to a better understanding of dietary habits and overweight/obesity in university students, and support the development of programs to promote healthy lifestyles in that population.

Abstract
Introduction
Iron deficiency is one of the most common nutritional disorders in the world affecting young females of the reproductive age group. Indeed, an ideal screening test should be capable of identifying iron deficiency long before developing anemia. Henceforth, the present study was aimed to determine utility of hepcidin in iron deficiency and to see its correlation with different iron indices.
Methods
This cross-sectional study was conducted in the Department of Biochemistry, SGT Medical College Hospital and Research Institute, Budhera, Gurugram, Haryana, India. It included 200 nonpregnant female students aged between 18 and 25 years. Estimation of hepcidin was by enzyme-linked immunosorbent assay. Quantitative estimation of serum iron, total iron-binding capacity (TIBC), and transferrin saturation was done via semi-autoanalyzer. Statistical analysis was done using SPSS v22.
Results
The reference range of urinary hepcidin established in this study was 110 to 969 ng/mg creatinine (mean ± standard deviation 328.3 ± 195.07 ng/mg creatinine). Serum hepcidin and urinary hepcidin had a significant correlation with iron indices. Area under the curve of urinary hepcidin was obtained with best combination of diagnostic sensitivity (82.6%) and specificity (83.1%) at a cutoff value of > 15.7 ng/mL and ≤ 199 ng/mg, respectively.
Conclusion
Since ferritin, TIBC, transferrin saturation, and hepcidin each represent different aspects of iron metabolism, incorporating hepcidin in the present diagnostics and combined evaluation of these indices may accord enhanced clinical information. Hepcidin would help to stratify the vulnerable young healthy female population in early stages of iron deficiency and guide proper interventions to reduce morbidity.

Abstract
Background: Aortic valve sclerosis (AVSc) is defined as the thickening and calcification
of aortic valve cusps, in the absence of obstruction of ventricular outflow.
AVSc is linked with a clear imbalance in some trace elements. Aims: The objective of this study was to investigate the relationship between AVSc
and serum levels of iron (Fe), zinc (Zn), selenium (Se), and copper (Cu).
Additionally, this research aimed to explore the clinical significance of
human serum zinc, selenium, copper, and iron concentrations as a potential
new biomarker for AVSc patients and to clarify the pathophysiological role
in individuals at risk of developing AVSc. Patients and methods: The study included 40 subjects with AVSc (25% male and 75% female) who were
compared with a healthy control group with the same gender ratio. AVSc was
based on comprehensive echocardiographic assessments. Blood samples were
taken and Zn and Cu concentrations were determined through the use of atomic
absorption spectroscopy. Se was measured using an inductively coupled plasma
mass spectrometry device and Fe was measured using a Beckman Coulter
instrument. Results: There was a significant difference in the prevalence of diabetes, blood
pressure levels, and body mass index between the patients and the healthy
subjects (p < 0.05). The differences between the serum
Fe, Se, and Cu levels of the AVSc patients and the healthy subjects
(p > 0.05) were recorded. The serum Zn of AVSc
patients when compared was significantly lower compared with that of the
control group (p < 0.01). Conclusion: Patients with AVSc had an imbalance in some of the trace elements in their
blood. The patient group’s valves had higher serum Cu levels and lower serum
Se, Zn, and Fe concentrations compared with the healthy group’s valves. In
the valve patients as compared, AVSc had a high prevalence of obesity,
hypertension, and diabetes.

Abstract
The levels of trace elements in whole blood and plasma have been widely used for assessing nutritional status and monitoring exposure and can vary widely in populations from different geographical regions. In this study, whole blood samples (n = 120) and plasma samples (n = 120) were obtained from healthy donors attending the Red Cross Blood Bank (Queensland Red Cross Blood Service), which provided information for age and sex. There were 71 males (age range: 19-73 years) and 49 females (age range: 18-72 years) for whole blood samples, and 59 males (age range: 19-81 years) and 61 females (age range: 19-73 years) for plasma samples. The main aim of the study was to provide information on blood reference levels of 21 trace elements (Ag, Al, As, Bi, Br, Cd, Co, Cr, Cu, Hg, I, Mn, Mo, Ni, Pb, Sb, Se, Tl, U, V, Zn) in Queensland. The study also aimed to assess differences in trace element blood levels between males and females and the effect of age. The trace element levels in blood samples were analysed using inductively coupled plasma mass spectrometry (ICP-MS) and the standard reference materials of Seronorm (Trace Elements Whole Blood) and UTAK (Trace Elements Serum) were used for quality control and assurance. The study found wide variations of trace element levels in whole blood and plasma, and generally the levels were comparable to other countries. No detectable levels were found for Bi, Cr, U and V in whole blood, but V levels were found in plasma samples. There were significant differences between males and females for whole blood Cu (p < 0.001), I (p = 0.009), Tl (p = 0.016) and Zn (p = 0.016). Significant differences were also found for plasma Cu (p < 0.001) and Se (p = 0.003) between males and females. There were trends of increased levels of blood Pb, Se and Zn with age. The study has provided further information on a wide range of trace elements in blood as reference levels for Queensland and Australia which are currently lacking.

Abstract
BACKGROUND Female undergraduate students may undergo many health implications due to the transition from secondary to undergraduate level. AIM The study was aimed to assess molar ratios of phytate to minerals (calcium, zinc, and iron) in the diets, and to measure the iron status of resident female students at Dhaka University. METHODS In total, 180 female students between 18-26 years of age from 3 dormitories of Dhaka University were selected for the study. Dietary intake information was collected over three consecutive days. Multiple-Pass 24-hour recall. Blood hemoglobin and serum ferritin levels were analyzed for sub-sample (20 participants from each dormitory). RESULTS The mean dietary intake of phytate, calcium, zinc, and iron were estimated at 347.11, 181.04, 6.59, and 7.14 mg/day, and hemoglobin and serum ferritin at 11.34 g/dl, and 18.48 ng/ml, respectively. The respective molar ratios of phytate: calcium, phytate: zinc, phytate: iron and phytate × calcium: zinc were 0.13, 5.27, 4.20, and 21.26 in the diet of the respondents. The prevalence of anemia, iron deficiency and iron deficiency anemia among the respondents was found to be 51.7%, 48.4%, and 28.3%, respectively. Linear regression analysis showed that only zinc intake had positive association with hemoglobin, while iron and zinc intake had a significant positive, and phytate:iron molar ratio had a significant negative association with serum ferritin concentration (p < 0.05). After adjusting all significant determinants of serum ferritin, no predictors have found significant. CONCLUSIONS Larger and more specific research is needed to clearly understand the mechanism behind anemia and iron deficiency among female residential students.

Abstract
Although simultaneous supplementation of iron and folic acid is justified, the potential interactions between these micronutrients and other elements are poorly known. In this study, we aimed to investigate the effect of iron and folic acid supplementation on the levels of selected essential and toxic elements in the serum of micronutrient-deficient young women. A total of 40 women participated in this study and were divided into two groups: study group (n = 23) (with iron and folate deficiency) and control group (n = 17). The study group received iron and folic acid supplements for 3 months. Blood samples were collected at baseline and after the completion of the study period. Women completed a 3-day food intake record. We calculated the body mass index (BMI) of all the participants. Cellular morphology was analyzed in whole blood, and biochemical parameters were determined in serum. Elements were measured in serum by inductively coupled plasma mass spectrometry (ICP-MS). According to our results, in the case of the study group, the supplementation of iron and folic acid restored their levels; however, it caused a significant decrease in the level of zinc, calcium, and magnesium. In the case of the control group, at the end of the study period, there was a marked decrease in the level of iron. Interestingly, there was an increase in the level of arsenic and vanadium in both groups. In conclusion, simultaneous supplementation of iron and folic acid impairs the level of zinc, calcium, and magnesium in women of childbearing age.

Abstract
Plant-based and flexitarian eating patterns are increasingly popular, and the food supply system has responded with a wide range of convenience products despite a lack of understanding regarding consumer views. The aim of this study was to explore consumer and nutrition professional (NP) perceptions and attitudes to plant protein, including plant-based meat alternatives (PBMA) within an Australian context. Using an online survey promoted via social media, 679 responses (89% completion rate), achieved an even spread across key age groups. A total of sixty percent reported following a special diet, with 25% vegan and 19% flexitarian. ‘Health’ was a key driver for diet type among the NPs (53.3%) and they were less likely to follow a special diet, while “ethical” reasons were cited by consumers (69%). Plant-based eating was considered a vegan dietary pattern and the most frequently consumed plant-based proteins were whole grains. Most (74%) had tried PBMA, but they were more frequently chosen by consumers, with burger patties then sausages and mince selected as a ‘trendy’ choice; taste was very important across both groups. Products mimicking chicken and fish were of less interest. Plant-based claims were observed by 78% but these were also of greater interest to consumers. Participants reported looking for whole ingredients and iron content and expected that both iron and vitamin B12 would be comparable to red meat. Sodium was the nutrient of greatest interest to NPs and, together, these results help inform the direction for product innovation, while also highlighting the need to assess the adequacy of the dietary pattern when promoting sustainable plant-based eating.

BACKGROUND Dried Urmia Lake in the northwest of Iran is a major regional source of sodium and toxic metal aerosols which may cause numerous health problems. The aim of this study was to evaluate iron-deficiency anemia (IDA) and some related risk factors among women of reproductive age in the suburb of dried Urmia Lake to provide the information about the problem to the health-care providers. METHODS This cross-sectional study was conducted on 278 healthy nonpregnant, nonlactating women aged 18-45 years, living in the rural area of the Salmas city, closest to the Urmia Lake between February and June 2017. The study participants were selected using a stratified random sampling method with proportional allocation from seven villages. A general questionnaire was completed for each participant to collect sociodemographic information and a 3-day dietary recall questionnaire to obtain daily dietary intakes. IDA was defined as a hemoglobin (Hb) level of <12 g/dl and ferritin concentration of <15 μg/l. Spearman's correlation coefficient and Fisher's exact test were applied to determine sociodemographic factors associated with the serum Hb and ferritin levels. RESULTS The prevalence of overall anemia (Hb <12 g/dl) was 7.9%. IDA was determined in 4.3% and iron deficiency (ID) in 19.1% (serum ferritin <15 μg/l) of the participants. There was a significant positive correlation between serum Hb concentrations and the mean daily intakes of protein and iron (P < 0.001). Similarly, a significant positive correlation was observed between serum ferritin levels and body mass index (P < 0.001). Significant inverse associations were found between Hb concentrations and the number of pregnancies and children (P < 0.001), as well as the number of family members (P < 0.05). CONCLUSIONS Results indicated a mild prevalence of IDA and a relatively high rate of ID among studied participants. Educational programs are needed to improve nutritional habits as well as the use of contraceptives to promote women's health.

[PMID: 33023762 DOI: 10.1016/j.clnu.2020.09.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 09/04/2020] [Accepted: 09/08/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND AIMS The clinical nutrition-eating disorders-unit in Raymond Poincaré Hospital is a reference center for the management of severe malnutrition and its complications in patients with anorexia nervosa (AN). The purpose of this study is to specify socio-demographic, anamnesic and clinical characteristics of AN patients hospitalized for extreme malnutrition, to identify types and prevalence of medical complications presented during their hospitalization for refeeding and the evolution of patients nutritional status. METHODS Demographic, clinical and paraclinical data of 354 severely malnourished AN patients were collected, during their first hospitalization in the unit, between November 1997 and January 2014, through medical records. The prevalence of medical complications was compared between the 2 AN subtypes (restricting and binging-purging). RESULTS 339 patients were female and mean age was 28.7 ± 10.7 years old. Duration of AN was 9.5 ± 9 years, 173 (48.9%) patients had a restricting AN subtype. BMI at admission was 12.2 ± 1.6 kg/m2, 280 (79.3%) patients had already been hospitalized for AN in other hospitals before. Psychiatric comorbidities were present in 168 (47.5%) patients. Associated somatic comorbidities concerned 70 (19.8%) patients. Outcomes during hospitalization were marked by 4.1 ± 3.9 kg weight gain on 36.9 ± 30.5 days. Enteral nutrition was provided in 304 (85.9%) patients. Main medical complications during hospitalization were: anemia (79%), neutropenia (53.9%), hypertransaminasemia (53.7%), osteoporosis (46.3%), hypokalemia (39.5%), hypophosphatemia (26%), hypoglycemia (13.8%), infectious complications (24.3%), cardiac dysfunction (7.1%), and proven gelatinous bone marrow transformation (6.5%). Hypokalemia was more frequent in binging-purging subtype. Lympho-neutropenia and hypertransaminasemia were more frequent in restricting subtype. During their hospitalization, 35 (10%) patients were referred to medical intensive care unit and 5 patients died. CONCLUSIONS AN patients hospitalized for severe malnutrition in a specialized clinical nutrition unit have severe and frequent medical complications. Psychiatric comorbidities are also frequent and could complicate medical care. A specialized and multidisciplinary management of these patients is therefore essential.

Abstract
Abstract
Aim
Vegetarian diets are increasingly popular, particularly among young women. However, exclusion of animal products from the diet increases the risk of micronutrient deficiencies, which is particularly unfortunate during pregnancy and childhood. A person needs a substantial amount of nutritional knowledge to achieve a nutritionally complete vegetarian diet. We have tested nutritional knowledge among well-educated young vegetarians and omnivores.
Subjects and methods
In October 2018, medical students at the University of Bergen, Norway (N = 880), were invited to take an anonymous survey to test their nutritional knowledge concerning micronutrients in vegetarian diets.
Results
The responses from the students (n = 394, 45%) were categorized according to diet: former or current vegetarians (24%) versus always omnivores (76%). Forty-five percent of the vegetarians and 28% of the omnivores did not consider it necessary to take supplements while following a vegetarian diet. Sixty-one percent of vegetarians and 38% of omnivores considered it possible to have a well-balanced vegan diet. Plant foods were wrongly considered to be a dietary source of vitamin B12 by 33% and of iodine by 20% of the students.
Conclusion
Nutritional knowledge concerning vegetarian diets was not optimal among Norwegian medical students, even if they had ever followed a vegetarian diet. As vegetarian diets are popular among the younger generation and pose a risk of micronutrient deficiencies, this is a public health concern. Nutrition education should be improved in the population. A more extensive integration of nutritional training in the medical curriculum must be implemented so doctors can give adequate nutritional guidance.

Relationship between Selenium and Hematological Markers in Young Adults with Normal Weight or Overweight/Obesity. Antioxidants (Basel) 2019; 8:antiox8100463. [PMID: 31597392 PMCID: PMC6826354 DOI: 10.3390/antiox8100463] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2019] [Revised: 10/01/2019] [Accepted: 10/05/2019] [Indexed: 12/21/2022] Open
Abstract
Selenium deficiency has been linked to anemia of inflammation, which is mediated by hepcidin. However, there are few studies providing evidence of the role of hepcidin in this relationship. In this study, we investigated the interrelationships among selenium biomarkers, hepcidin concentration, and iron status among individuals with overweight/obesity compared to their normal weight counterparts, since obesity is associated with chronic inflammation. A total of 59 college students were recruited for this study. Fasting blood samples were collected for the analysis of iron status, plasma selenoproteins (glutathione peroxidase (GPX) activity and selenoprotein P (SEPP1)), and plasma hepcidin. Subjects completed three-day dietary records to determine average daily nutrient intakes. SEPP1 concentration, GPX activity, and iron status biomarkers (serum iron, transferrin saturation, and hemoglobin concentration) were lower among individuals with overweight/obesity compared with individuals with normal weight, but these differences were not significant (p > 0.05). Regression analysis showed that GPX activity (β = −0.018, p = 0.008) and SEPP1 concentration (β = −1.24, p = 0.03) were inversely associated with hepcidin concentration. The inverse association between selenoproteins and hepcidin concentration supports a potential role of hepcidin as a mediator between selenium and iron status and warrants further studies to better understand this relationship.

Abstract
BACKGROUND Dietary composition is the cornerstone of weight management. This study aimed to investigate the effect of nutrient intakes on anthropometric profiles among university students. METHODS This cross-sectional study was conducted among 411 students aged 18-29 years, purposive sampled from a selected private university in Klang Valley, Malaysia. Anthropometric profiles were measured. Nutrient intakes were assessed by 3-day 24-hour diet recalls. RESULTS Respondents on average had adequate macronutrient intakes, however, total consumption of dietary fiber and micronutrients were fell short of recommended levels. Significant negative associations were found between body mass index (BMI) and all the macronutrients, calcium, thiamine, riboflavin and niacin. Body fat percentage was significantly associated with all the macronutrients, calcium, zinc, thiamine and niacin. Significant inverse associations were also found between waist circumference and carbohydrate, fiber, thiamine, riboflavin and niacin. Visceral fat showed significant inverse associations with carbohydrate, fat, fiber, thiamine, riboflavin and niacin. Further, after adjusting for sex, gender and race, BMI was associated with niacin (β=-0.161, p=0.027). Body fat percentage was also found significantly associated with niacin (β=-0.180, p=0.002) and riboflavin (β=-0.132, p=0.014). CONCLUSION Micronutrients, especially B vitamins, are important in weight management among the young adults.

Abstract
BACKGROUND: Folate and vitamin B12 are essential micronutrients, the deficiency of which can be associated with public health problems worldwide. AIM: The aims of this study were to assess the folate and vitamin B12 status of healthy adults and the effect of gender differences on their deficiency using serum folate, vitamin B12 and red blood cell (RBC) folate as biomarkers and their relation to hematological indices. METHODS: This study was a part of the Azar cohort study, which is designed as a noncommunicable disease survey in the population of Shabestar, East Azerbaijan, Iran. A total of 95 healthy adults (35 men, 60 women) were chosen according to exclusion criteria and assessed using demographic characteristics and blood sampling. RESULTS: Low concentrations of serum folate, vitamin B12 and RBC folate were detected in 16.8%, 61.1% and 40% of all subjects, respectively. Prevalence of low serum folate and vitamin B12 was higher in men than women (25.7% versus 11.7% for serum folate, 77.1% versus 51.7% for serum vitamin B12).A significant positive correlation was found between hemoglobin and serum folate, vitamin B12 and RBC folate concentrations ( r = 0.279, 0.335, 0.228, respectively). No statistically significant correlation between mean corpuscular volume and serum folate, vitamin B12 and RBC folate was seen ( r = -0.049, -0.030, -0.016, respectively). CONCLUSIONS: There was a high prevalence of low folate and vitamin B12 concentrations in our community. Regarding the impact of these two vitamins deficiency on overall health, we suggest further investigations with more participants. In addition, monitoring hematological indices could be useful in people with folate and vitamin B12 deficiency.

Abstract
OBJECTIVES This study aims to assess adequacy in micronutrient intake in comparison with reference nutrient intakes (RNI) and to identify differences in intakes between normal weight and overweight individuals. STUDY DESIGN A sample of 542 university students (18-25 years), normal weight (N = 369) and overweight (N = 173), were included in a cross-sectional study. METHODS A three-day diet diary was used to assess energy and nutrient intake. Body mass index (BMI) and waist circumference were measured. RESULTS Mean dietary vitamin D intake was lower than RNI in both men (4.44 μg) and women (5.04 μg). Mean intakes of calcium (597.44 mg), iron (8.62 mg) and folate (171.29 mg) were also lower than recommendations in women. Weight status (normal weight versus overweight) was significantly associated with micronutrient intake, and a trend towards a decrease in vitamin and mineral intake with increasing weight was noted. CONCLUSIONS Results suggest the need to increase the intake of some micronutrients to meet the RNI, to ensure optimal health. This study provides a helpful tool to reinforce recommendations and potential health promotion and intervention strategies in university settings and could influence manufacturers involved in new food product development targeted to this young population.

Abstract
Selenium was suggested to play a role in modulating cognitive performance and dementia risk. Thus, this study aimed to investigate the association between selenium status and cognitive performance, as well as inflammatory and neurotrophic markers in healthy older adults. This cross-sectional study included 154 older adults (≥60 years) from Victoria, Australia. Participants were assessed for cognitive performance (Cogstate battery), dietary selenium intake (two 24-h food recalls), plasma selenium concentration, inflammatory markers (interleukin (IL)-6, -8, -10, tumor necrosis factor-alpha and adiponectin) and neurotrophic factors (brain-derived neurotrophic factor, vascular endothelial growth factor and insulin-like growth factor 1). Dietary selenium intake was adequate for 85% of all participants. The prevalence of selenium deficiency was low; only 8.4% did not have the minimum concentration in plasma required for optimization of iodothyronine 5' deiodinases activity. Multiple linear regression analysis revealed that plasma selenium was not associated with cognitive performance, inflammatory markers nor neurotrophic factors, independent of age, sex, body mass index (BMI), habitual physical activity, APOE status, education, and history of cardiovascular disease. The lack of association might be due to the optimization of selenoproteins synthesis as a result of adequate selenium intake. Future prospective studies are recommended to explore potential associations of selenium status with age-associated cognitive decline.

Abstract
Background: There is a tendency to report micronutrients intakes collectively for adults, with broad age ranges being used. This means that certain sub-population groups such as young adults are often overlooked. The objective of the present article was to derive and evaluate micronutrient intakes across UK adults in their twenties, thirties, forties and fifties. Methods: A secondary analysis of the UK National Diet and Nutrition Survey (years 1-6) was undertaken. Data from n = 3,238 adults was analyzed and micronutrient intakes from food sources (excluding supplements) derived as a percentage of the Reference Nutrient Intake (RNI) and percentage below the Lower Reference Nutrient Intake (LRNI) for males and females aged 20-29, 30-39, 40-49, and 50-59 years. Mean intakes were used in instances where this data was unavailable (for vitamins D and E). Results: Sizeable gaps were found for magnesium with 19% of young people in their twenties having intakes below the LRNI. Amongst UK females intakes of 9 micronutrients (riboflavin, vitamin B6, B12, folic acid, calcium, iron, magnesium, potassium, and iodine) were significantly lower than males aged 20-59 years (p < 0.001) expressed as a percentage of the RNI. Young adults in their twenties had significantly lower (p < 0.05) intakes of 8 micronutrients (vitamin A, riboflavin, folic acid, calcium, magnesium, potassium, iodine, and copper) expressed as a percentage of the RNI compared with adults in their thirties, forties and fifties. There were also considerable gaps in dietary selenium intakes with 50.3% females and 25.8% males having total intakes beneath the LRNI. A quarter of women had iron (25.3%) and potassium (24.3%) intakes below the LRNI. Conclusions: UK females and younger adults appear to be particularly vulnerable to micronutrient shortfalls from food sources alone. Clearly, improvements in dietary quality are needed across mid-life. Alongside this, fortification and supplementation strategies may be considered to help adults achieve dietary targets at this life-stage when they should be at their nutritional prime.

Abstract
Selenium (Se) protects cells against oxidative stress damage through a range of bioactive selenoproteins. Increased oxidative stress is a prominent feature of Alzheimer's disease (AD), and previous studies have shown that Se deficiency is associated with age-related cognitive decline. In this study, we assessed Se status in different biofluids from a subgroup of participants in the Australian Imaging, Biomarkers and Lifestyle Flagship Study of Ageing. As Se in humans can either be an active component of selenoproteins or inactive via non-specific incorporation into other proteins, we used both size exclusion chromatography-inductively coupled plasma-mass spectrometry (SEC-ICP-MS) and tandem mass spectrometry to characterize selenoproteins in serum. We observed no differences in total Se concentration in serum or cerebrospinal fluid of AD subjects compared to mildly cognitively impairment patients and healthy controls. However, Se levels in erythrocytes were decreased in AD compared to controls. SEC-ICP-MS analysis revealed a dominant Se-containing fraction. This fraction was subjected to standard protein purification and a bottom-up proteomics approach to confirm that the abundant Se in the fraction was due, in part, to selenoprotein P. The lack of change in the Se level is at odds with our previous observations in a Brazilian population deficient in Se, and we attribute this to the Australian cohort being Se-replete.

Iron is an essential micronutrient for human health and inadequate intake may result in iron deficiency (ID) or iron deficiency anaemia (IDA). Unlike other recent studies investigating iron status in young women, this cross-sectional study analysed dietary intake and biochemical data from healthy young (18-35 years) women (n = 299) to determine the association between both haem iron (HI) and non-haem iron (NHI) intakes and serum ferritin (SF). Dietary restraint and possible inflammation secondary to obesity were also measured and accounted for, and energy intake was adjusted for using the residuals method. Independent samples t-tests and chi-squared tests were performed, and factors found to be significantly different between iron replete (IR) and ID/IDA participants were analysed using general linear modelling. ID/IDA participants consumed significantly lower total energy than iron replete (IR) (p = 0.003). Lower energy intake was also associated with higher levels of dietary restraint (p = 0.001). Both HI and NHI were positively associated with SF with HI was found to be a stronger predictor (β = 0.128, p = 0.009) than NHI (β = 0.037, p = 0.028). The study demonstrates that intake of both HI and NHI, as well as adequate dietary energy, are associated with normal iron status levels in young women, and that restrained eaters may be at greater risk of low iron status.

Alzaheb RA, Al-Amer O. The Prevalence of Iron Deficiency Anemia and its Associated Risk Factors Among a Sample of Female University Students in Tabuk, Saudi Arabia. CLINICAL MEDICINE INSIGHTS. WOMEN'S HEALTH 2017; 10:1179562X17745088. [PMID: 29225484 PMCID: PMC5714083 DOI: 10.1177/1179562x17745088] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/18/2017] [Accepted: 10/23/2017] [Indexed: 11/21/2022]
Abstract
BACKGROUND Prior data on iron deficiency anemia's (IDA) prevalence and associated risk factors among female university students are scarce in the Saudi Arabian context. This study therefore recruited a sample of female students at the University of Tabuk, Saudi Arabia, to investigate IDA prevalence and risk factors and fill the identified research gap. METHODS A cross-sectional study of 200 apparently healthy female students aged between 19 and 25 years was performed between February and June 2016. Data on the participants' sociodemographics, diet, health, anthropometry, and hematological and biochemical iron status indices were gathered. A logistic regression analysis then revealed the IDA risk factors. RESULTS The IDA prevalence was 12.5%. The factors associated via logistic regression with an elevated anemia risk were inadequate iron and vitamin C intakes, infrequent (≤2 times per week) consumption of red meat, frequent (≥2 times per week) tea consumption, and a past personal history of IDA. CONCLUSIONS The findings suggest that focused education and awareness strategies are needed to improve nutritional habits by encouraging the consumption of rich dietary iron sources and by raising awareness of the food and drinks which facilitate or hinder the bioavailability of iron.

Abstract
Women of reproductive age are at increased risk for iron deficiency (ID) and iron deficiency anemia (IDA), with both implicated in decreased cognitive function (CF). Obesity may complicate this association via inflammatory-mediated ferritin elevation. This cross-sectional study examined the association between hematological iron status (iron replete (IR), ID or IDA) and CF in healthy, young (18-35 years) women of normal-weight (NW: BMI 18.5-24.9 kg/m²) or obese-weight (OB: BMI >30 kg/m²). Participants completed a validated, computer-based cognition assessment evaluating impulsivity, attention, information processing, memory and executive function; CF reported as z-scores (mean ± SD). Iron status and CF were compared between groups via ANOVA, with adjustment for potential confounders (BMI, physical activity, C-reactive protein) via ANCOVA. A total of 157 NW and 142 OB women (25.8 ± 5.1 years) participated. Prevalence of ID and IDA were 14% and 6% respectively, with no significant difference between NW and OB groups. Women with IDA scored significantly lower on attention (although within normal range; ±1 z-score), compared to ID (IDA: -0.75 ± 1.89; ID: 0.53 ± 1.37; p = 0.004) but not IR (0.03 ± 1.33, p = 0.21) groups; there were no significant differences between ID and IR groups (p = 0.34). Adjustment for confounders did not significantly alter these results. In conclusion, women with IDA showed significantly reduced attention compared to women with ID.

Abstract
Women have an increased risk for chemical element deficiencies during reproductive age, particularly due to higher chemical element requirements and poor diets. Twenty-one chemical elements (Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Se, Si, Sn, Sr, Ti, V and Zn) in hair samples, which were collected from 71 non-pregnant and 236 pregnant women living in the West Ujimqin Banner, central Inner Mongolia, China, were measured, and the environment, dietary habits and ethnic group influence factors associated with the biomarker were analyzed. The results indicated that the average values of the chemical element contents from hair were greatly different compared to those from other areas, especially the Al, Cd, Pb, Ca and Sr contents. There was no significant difference among the three ethnicities for any element except Mn and Ti in non-pregnant women. Compared to non-pregnant women, in the first trimester group, the levels of nine chemical elements (Ba, Cd, Cu, Pb, Se, Si, Sn and Ti) decreased, while the others increased, and the contents of all of the chemical elements decreased in the second trimester group, while in the third trimester, there was a slight increase. Three chemical elements (Cu, Mn and Zn) displayed a synergistic correlation between each other in the third trimester group, which may protect the placenta from some oxidant damage. The high levels of Cd and Pb in hair likely originate from house renovations and traffic pollution. This study provided basic and useful information on the levels of chemical elements in reproductive-age women, and the results of this study are helpful to control the contents and improve the health of pregnant and non-pregnant women.

Abstract
OBJECTIVE To assess serum B12, folate and the associated homocysteine (Hcy) levels among women of childbearing age in the UK and examine their association with dietary intake in relation to the UK Recommended Nutrient Intakes (RNIs) for B12 and folate. DESIGN Cross-sectional study. SETTING Data from two publicly available National Diet and Nutrition Surveys (NDNS 2000/2001 and 2008/2012) were used. These were population-based surveys of randomly selected samples of adults which were carried out in their households. PARTICIPANTS Women of childbearing age (aged 19-39 years), representative of the UK population. Those who were pregnant or breastfeeding were excluded. OUTCOME MEASURES The associations between micronutrient intakes and blood levels of B12, folate and Hcy were assessed by correlation and stepwise linear regression. B12 intake was divided into quintiles and plotted against blood B12 and Hcy concentrations to determine the threshold of any associations. RESULTS 299 women from the first NDNS cohort had complete intake and biomarker data. The prevalence of serum vitamin B12 (≤150 pmol/L) and serum folate (≤10 nmol/L) deficiency and hyperhomocysteinemia (≥12 µmol/L) was 12.4%, 6.4% and 21.2%, respectively, despite seemingly adequate B12 intakes (median 3.8 μg/day, 96% consumed more than the UK RNI of 1.5 μg/day). B12 concentrations increased across all quintiles of intake with serum levels in quintiles 4 and 5 (median intake 4.9 and 7.1 μg/day, respectively) significantly higher than quintile 1. However, Hcy concentrations levelled off between quintiles 4 and 5. Comparison of micronutrient intake between the two surveys found that folate intake has reduced in the more recent cohort. CONCLUSIONS The UK RNI for B12 intake should be increased for women of childbearing age with intakes of around 5-7 μg/day likely to be associated with stable biomarker levels. B12 levels should also be measured in women preconceptionally or in early pregnancy given the high rates of deficiency.

Abstract
A novel fluorescent bis-calix[4]arene macrocycle 9 incorporating metal-binding pockets was successfully prepared. The structure of macrocycle 9 and its precursors were characterized via EI-MS, MALDI-TOF-MS, ESI-MS, (1)H NMR, (13)CNMR, 2D NMR, and X-ray crystallography. The macrocycle 9 displayed selective fluorescence quenching after interacting with Cu(2+) in the presence competing metal cations including Mg(2+), Ca(2+), Ba(2+), Ag(+), Zn(2+), Ti(4+),Cd(2+), Hg(2+), Pb(2+), In(3+), La(3+), Cr(3+), Ni(2+), Sb(3+), V(5+), Fe(3+), Co(2+), Sn(2+), Sn(2+), and Tl(+). The Cu(2+) limit of detection was found to be 40 nM much lower than its threshold level (∼ 20 μM) in drinking water permitted by the U.S Environmental Protection Agency (EPA). Furthermore, drinking water samples from Karachi University (Pakistan) spiked with Cu(2+) were analysed with the sensing system and the results showed an excellent agreement with the fluorescence quenching phenomenon of macrocycle 9 examined in deionized water. Importantly, the chemosensor 9 could be used to detect Cu(2+) in living cells.

Low Cobalamin Levels as Predictors of Cobalamin Deficiency: Importance of Comorbidities Associated with Increased Oxidative Stress. Am J Med 2016; 129:115.e9-115.e16. [PMID: 26239093 DOI: 10.1016/j.amjmed.2015.07.017] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2015] [Revised: 06/30/2015] [Accepted: 07/01/2015] [Indexed: 11/23/2022]
Abstract
BACKGROUND Cobalamin (B12) deficiency can lead to irreversible neurocognitive changes if unrecognized. Screening involves measurement of serum cobalamin levels, but the sensitive metabolic indicators of cobalamin deficiency, methylmalonic acid (MMA) and homocysteine (HCys), may be normal when cobalamin values are low and elevated when cobalamin values are normal. Because cobalamin is inactivated by oxidation, the relationship between these metabolites and comorbidities associated with increased oxidative stress (oxidant risks) in subjects with low and low-normal cobalamin levels was studied. METHODS A retrospective record-review was conducted of community-dwelling adults evaluated for cobalamin deficiency during a 12-year period with serum cobalamin values in the low (≤ 200 pg/mL; n = 49) or low-normal (201-300 pg/mL; n = 187) range and concurrent measurement of MMA. RESULTS When "No" oxidant risk was present, elevated MMA (>250 nmol/L) and HCys (>12.1 μmol/L) values occurred in 50% and 30% of subjects, respectively (P <.01). In contrast, when "Three or More" oxidant risks were present, mean MMA and HCys values were significantly higher, and elevated MMA and HCys values occurred in 84% and 78% of these subjects, respectively (P ≤.012). Pharmacologic doses of cyanocobalamin significantly decreased metabolite values in ≥ 94% of treated subjects. CONCLUSION In subjects with low or low-normal cobalamin values, metabolic evidence of cobalamin deficiency is more frequent when 3 or more oxidant risks are present. Thus, defining a low serum cobalamin level to screen for cobalamin deficiency may be a "moving target" due to the variable presence and severity of often subtle, confounding clinical conditions in individual subjects.
