Current Screening

Current screening guidelines may not be adequate to identify iron deficiency (ID) and iron deficiency anemia (IDA) in adolescent and young adults. Adolescent and young adult outpatients from 4 hospital-based clinics (N = 493) reported on diet, health, and bleeding, and had phlebotomy for iron and hematologic tests. We examined sex-specific factors associated with ID and IDA and ability of universal and risk factor–based screening using hemoglobin and hemoglobin plus ferritin to detect ID and IDA. Among females (n = 350), 34.6% had ID and 6.3% had IDA. Nearly 1 in 3 females with ID had no risk factors. Among males, 12.6% had ID; none had IDA. More than 1 in 3 males with ID did not have risk factors. Current screening approaches would have missed ID in 47% to 82% of females and 95% to 100% of males. ID was prevalent in both male and female adolescents and young adult outpatients. New approaches to screening for ID are needed to accurately evaluate iron status in this population.

Prevalence Of Anemia

Abstract BACKGROUND Prevalence of anemia and iron deficiency (ID) are higher among indigenous children in Canada, although few data are available in Quebec. Iron is metal that interact with the absorption of manganese (Mn) and Lead (Pb) cobalt (Co). ID is known to upregulate these metals, thereby increasing their absorption, concentration inside the body and their toxicity. OBJECTIVES The objectives of the present study are to: (i) Characterize ID and anemia prevalence and their protective/risk factors; and (ii) Study associations between blood Mn, Pb and iron status biomarkers. DESIGN/METHODS Data from The 2015 First Nation Youth Health and Environment Pilot Study was conducted among children (3 to 19 y, n = 198) from four First Nations communities in Quebec will be used in these study where, blood samples and anthropometric measures were collected, hemoglobin was measured on site using an Hemocue analyser. Protective/risk factors including education, food security, housing conditions and lifestyle and dietary habits were documented using interview-administered questionnaire to children’ parents. Serum ferritin and blood Pb, Mn, Co, Zn and Ca were measured by Modular P analyser and ICPMS. Descriptive and multiple regression statistical analyses adjusting for relevant co-variables were used. RESULTS Results showed ID and anemia prevalence of 20.7% and 17.6% respectively, among which 8.8% presented iron deficiency anemia. Moreover, up to 11.9% had elevated blood Mn (median = 15.9 µg/L, range 7.1 to 31.9 µg/L) of which 27.5% presented ID. However, blood Pb was low (median = 5.4 µg/L, range 1.8 to 50.8 µg/L). Multiple logistic regression analysis showed that crystal juice intake was associated with lower ID and anemia (OR (95%): 0.50 (0.30 - 0.82) and 0.47 (0.26 - 0.87) respectively) in girls. Likewise, the presence of hunter in the household was associated with lower anemia in girls (0.09 (0.02 - 0.53)). No factors were associated with ID in boys, and for anemia, lower serum ferritin and older age was associated with higher prevalence of anemia (1.08 (1.01 - 1.14) and 1.23 (1.02 - 1.48) respectively). In adjusted models, blood Mn was negatively associated with serum ferritin concentrations (ß = -0.05; p < 0.02) in girls and positively associated with blood Co (ß = 8.50; p < 0.01) in boys. CONCLUSION Findings on high prevalence of ID, anemia and elevated blood Mn among children form these First Nation communities support that, community and family activities increasing traditional foods consumption improve nutritional status and suggest that foods and beverages naturally rich in vitamin C - but lower in added sugar than crystal juice - would improve iron intake in girls, which would contribute to improve their iron status, decrease anemia and restore normal Mn blood levels.

Oral contraceptive use has been associated with decreased menstrual blood losses; thus, can independently reduce the risk of anemia and iron deficiency in women. Manufacturers have recently started to include supplemental iron in the non-hormonal placebo tablets of some contraceptives. The aims of this narrative review are: (i) to describe the relationship between oral contraceptive use and both anemia and iron status in women; (ii) to describe the current formulations of iron-containing oral contraceptives (ICOC) available on the market; and (iii) to systematically review the existing literature on the effect of ICOC on biomarkers of anemia and iron status in women. We discovered 21 brands of ICOC, most commonly including 25 mg elemental iron as ferrous fumarate, for seven days, per monthly tablet package. Our search identified one randomized trial evaluating the effectiveness of ICOC use compared to two non-ICOC on increasing hemoglobin (Hb) and iron status biomarker concentrations in women; whereafter 12 months of contraception use, there were no significant differences in Hb concentration nor markers of iron status between the groups. ICOC has the potential to be a cost-effective solution to address both family planning needs and iron deficiency anemia. Yet, more rigorous trials evaluating the effectiveness of ICOC on improving markers of anemia and iron deficiency, as well as investigating the safety of its consumption among iron-replete populations, are warranted.

Abstract Background: Iron deficiency and iron deficiency anemia have been shown to have negative effects on aspects of perception, attention, and memory. Objective: The purpose of this investigation was to assess the extent to which increases in dietary iron consumption are related to improvements in behavioral measures of perceptual, attentional, and mnemonic function. Methods: Women were selected from a randomized, double-blind, controlled food-fortification trial involving ad libitum consumption of either a double-fortified salt (DFS) containing 47 mg potassium iodate/kg and 3.3 mg microencapsulated ferrous fumarate/g (1.1 mg elemental Fe/g) or a control iodized salt. Participants' blood iron status (primary outcomes) and cognitive functioning (secondary outcomes) were assessed at baseline and after 10 mo at endline. The study was performed on a tea plantation in the Darjeeling district of India. Participants (n = 126; 66% iron deficient and 49% anemic at baseline) were otherwise healthy women of reproductive age, 18–55 y. Results: Significant improvements were documented for iron status and for perceptual, attentional, and mnemonic function in the DFS group (percentage of variance accounted for: 16.5%) compared with the control group. In addition, the amount of change in perceptual and cognitive performance was significantly (P < 0.05) related to the amount of change in blood iron markers (mean percentage of variance accounted for: 16.0%) and baseline concentrations of blood iron markers (mean percentage of variance accounted for: 25.0%). Overall, there was evidence that the strongest effects of change in iron status were obtained for perceptual and low-level attentional function. Conclusion: DFS produced measurable and significant improvements in the perceptual, attentional, and mnemonic performance of Indian female tea pickers of reproductive age. This trial was registered at clinicaltrials.gov as NCT01032005.

Purpose Iron deficiency anemia (IDA) is one of the most major micronutrient deficiencies worldwide. Food fortification is one strategy for reducing IDA in the population despite concern regarding the gut pathogenic bacteria overgrowth. The purpose of this study was to evaluate the effect of iron encapsulation in banana peel matrix on iron status and gut microbiota composition in iron deficiency anemia. Design/methodology/approach Anemia was induced in 35 male Sprague Dawley rats of age two weeks by the administration of iron-free diet for two weeks. Rats then randomly divided into control, iron-fortified tempeh (temFe) dose 10 and 20 ppm, iron matrix-fortified tempeh dose 10 and 20 ppm and iron matrix fortified tempeh dose 10 and 20 ppm with probiotic mixture. Blood was drawn at Weeks 2 and 6 for hemoglobin and serum iron analysis. Rats were sacrificed at the end of Week 6, and cecal contents were collected for Lactobacillus, Bifidobacteria and Enterobactericeae analysis. Findings Hemoglobin and serum iron were significantly increased (p < 0.05) in all iron-fortified group with the highest value found in iron matrix dose 20 ppm (10.71 ± 0.15 g/dl and 335.83 ± 2.17 µg/dl, respectively). The cecal Lactobacillus and Bifidobacteria did not differ significantly between groups. Cecal Enterobactericeae was significantly different (p < 0.05) among groups with the lowest level in the temFe-20 (2.65 ± 0.78 log CFU) group. Research limitations/implications The use of commercial inoculum instead of pure Rhizopus oligosporus mold for developing the fortified tempeh may impact the effect of product on cecal gut microbiota composition, as different molds and lactic acid bacteria can grow in tempeh when using commercial inoculum. Social implications In Indonesia, iron fortification is conducted primarily in noodles and flour that limits the impact of iron fortification for reducing IDA in population. Iron fortification in food that was daily consumed by people, that is, tempeh, is potential strategy in reducing IDA in population. Originality/value Tempeh fortification using encapsulated iron improved iron status and gut microbiota composition in iron deficiency anemia.

Iron deficiency anemia (IDA) is a serious significant public health problem, since it’s negative impact on physicaland psycological development, behavior and work capacity. There are many risk factors influencing the development of IDA.A cross-sectional study has been conducted in 301 Junior High School students at East Jakarta in January-February 2000.A structural questionnaire, physical, cell blood count (CBC) and Serum Iron ( SI ) examinations were performed. We foundsome of the many variables were connected with IDA by using bivariat analysis. Anemia was found in 41 out of 301 students(13,6%) and only 25 children (8.3%) suffered from IDA. Among 179 female students, only 33 children (18.5%) were anemicand 20 out of 33 (12.0%) have IDA. Bivariat analysis revealed a significant association between IDA with sex, parent’seducation, food frequency questionnaire (FFQ) scores, and menstruation. It is concluded that the prevalence of IDA in thisstudy was lower than found in some previous studies in Indonesia. Gender, menstruation, low educated parents, and low FFQscores were risk factors for IDA.

Introduction. Neonatal calves are often deficient in iron. Accumulating evidence indicates that iron status is associated with disease pathologies including diarrhea. Our objective was to examine the association between iron status and gut function in neonatal calves with and without a history of calf diarrhea. Materials and Methods. Calves were divided into two groups based on their history of diarrhea; the first group were diarrheic calves (n=6) and the second group were non-diarrheic healthy calves (n=6). Blood samples (n=12) were collected at day 12 of age and erythrogram determination and measurements of serum iron and total iron binding capacity were performed. Hematological values were measured using an automatic analyzer, and biochemical properties were determined spectrophotometrically. Fecal samples were obtained from all calves and pH measured using semi quantitative test strips as well as being examined by bacterial cultivation for enterotoxigenic Escherichia coli, Salmonella spp. and Clostridium perfringens, by RT-PCR for the presence of bovine rotavirus, bovine coronavirus and bovine viral diarrhea virus, and by microscopy for the presence of Cryptosporidium parvum. Results and Conclusions. There were significant iron-related changes for most hematological indices in diarrheic calves; and iron (Fe) deficiency and microcytic, hypochromic anemia were diagnosed. The pH of the feces was significantly higher in diarrheic calves than in the non-diarrheic healthy group (P<0.01). All fecal samples were negative for the analyzed enteric pathogens. According to the results obtained, calves experiencing iron deficiency anemia exhibit changes in gut function leading to diarrhea as compared with a matched group of healthy calves.

Background: Hepcidin-25 is a 25 amino acid hepatokine and a key regulator of iron metabolism related to iron deficiency anemia. Recent studies have suggested that an elevated hepcidin level is correlated with low energy availability. Leptin is an appetite-suppressing adipokine and has been reported to stimulate hepcidin production in animals and cultured cells. While leptin is modulated by exercise, it is known that endurance runners and sprinters practice different types of exercise. This study investigated and compared the relationships between hepcidin and leptin levels, iron status, and body fat to understand better the risk of iron deficiency anemia in endurance runners and sprinters.Methods: Thirty-six male college track and field athletes (15 endurance runners and 21 sprinters) were recruited for this study. Dietary intake, body composition, and blood levels of ferritin, hepcidin-25, leptin, and adiponectin were measured. Correlations between hepcidin levels and ferritin, body fat, leptin, and adiponectin were evaluated using Pearson's correlation coefficient for each group.Results: The endurance runners had lower hepcidin levels and higher leptin and adiponectin levels compared with sprinters. Ferritin was positively correlated with hepcidin-25 levels in both the endurance and sprinter groups. A positive correlation was observed between hepcidin-25 and body fat or leptin levels only in sprinters.Conclusion: This is the first study investigating the relationship between blood levels of hepcidin and leptin in athletes. The positive correlation between hepcidin-25 and leptin was observed in sprinters but not endurance runners.
