Abstract
BACKGROUND Whether iron intake can affect cardiovascular disease (CVD) and dyslipidemia is controversial. However, few studies have focused on reducing the risk of CVD in people at risk for dyslipidemia. This study explored the linear relationship and possible nonlinear relationship between CVD and dyslipidemia. METHODS Dietary data were obtained from the China Health and Nutrition Survey between 2004 and 2015. The survey included 8173 participants older than 18 years. CVD risk was estimated by the Framingham risk score (FRS). Logistic regression analysis was used to determine whether iron intake affects CVD incidence and lipid profiles. The nonlinear association was tested with restricted cubic splines (RCSs). RESULTS For males, higher total iron intake [the fifth quintile (Q) vs. Q1 odds ratio (OR): 0.335, 95% confidence interval (CI): 0.248-0.453], heme iron intake (OR: 0.679, 95% CI: 0.492-0.937) and non-heme iron intake (OR: 0.362, 95% CI: 0.266-0.492) reduced CVD incidence. Heme iron intake increased high low-density lipoprotein cholesterol (LDL-C) (OR: 1.786, 95% CI: 1.226-2.602), high total cholesterol (TC) (OR: 2.404, 95% CI: 1.575-3.669), high triglyceride (TG) (OR: 1.895, 95% CI: 1.423-2.523), and low apolipoprotein A1/apolipoprotein B (ApoA-1/ApoB) risk (OR: 1.514, 95% CI: 1.178-1.945). Moderate non-heme iron intake reduced high-density lipoprotein cholesterol (HDL-C) incidence (Q5 vs. Q1 OR: 0.704, 95% CI: 0.507-0.979). For females, higher total iron intake (Q5 vs. Q1 OR: 0.362, 95% CI: 0.266-0.492) and non-heme iron intake (OR: 0.347, 95% CI: 0.154-0.781) reduced CVD incidence. Heme iron intake increased high LDL-C (OR: 1.587, 95% CI: 1.160-2.170) and high TC incidence (OR: 1.655, 95% CI: 1.187-2.309). CONCLUSIONS Men, especially those at risk of developing dyslipidemia, should consume non-heme rather than heme iron to reduce CVD incidence. For women, increased heme iron intake did not reduce CVD incidence. Therefore, women should minimize their heme iron intake to prevent dyslipidemia.

Abstract
INTRODUCTION Anemia and iron deficiency are the most common pathologies in pregnancy and associated with adverse pregnancy outcome. As patients with rheumatic diseases are also at high risk for anemia, we aimed to investigate the frequency of anemia and iron deficiency during pregnancy in this group and whether anemia is a risk factor for adverse maternal or child outcome. METHODS We analyzed 368 pregnancies from a German registry for pregnancies in patients with rheumatic diseases (TURIRE) from 2014-2022. Anemia and iron deficiency were defined according to the World Health Organization. Main outcome measures were prevalence of anemia, iron deficiency, and adverse outcomes. RESULTS From the 368 patients 61% were diagnosed with a connective tissue disease, 16% with rheumatoid arthritis or juvenile idiopathic arthritis, 14% with spondyloarthritis, 3% with vasculitis and 7% with other. Prevalence of anemia/iron deficiency was 18%/28% in the first, 27%/51% in the second and 33%/62% in the third trimester. Low hemoglobin levels (OR 0.52) or iron deficiency (OR 0.86) had a negative impact on child outcome. However, lower hemoglobin levels were associated with a lower risk for maternal complications (OR 1.47). CONCLUSION Prevalence of anemia and iron deficiency is high in pregnant women with rheumatic diseases. Compared to previously published cohorts of the general population from different countries, the prevalence of anemia and iron deficiency is distinctly higher. Furthermore, patients with rheumatic diseases already start with impaired iron storage and/or hemoglobin levels. Thus, iron supplementation should be initiated early on in this vulnerable in this patient group.

Abstract
Metabolic-associated fatty liver disease (MAFLD) has been proposed to replace the term non-alcoholic fatty liver disease (NAFLD) in 2020. The association between micronutrients and MAFLD has not been reported. Therefore, this study aims to explore the association between micronutrients intake and MAFLD. This was a cross-section study based on the National Health and Nutrition Examination Survey (NHANES). The dietary intake of copper, zinc, iron, and selenium was evaluated using the 24-h dietary recall interview. Logistic regression analysis was used to explore the association between micronutrients and MAFLD, and the results were shown as odds ratio (OR) with 95 % confidence intervals (CIs). A total of 5976 participants were finally included for analysis, with 3437 participants in the MAFLD group. After adjusting potential confounders, copper intake at quartile Q3 (OR = 0⋅68, 95 % CI 0⋅50, 0⋅93) and Q4 (OR = 0⋅60, 95 % CI 0⋅45, 0⋅80) was found to be associated with lower odds of MAFLD. Iron intake at Q2 (OR = 0⋅64, 95 % CI 0⋅45, 0⋅92) and Q3 (OR = 0⋅61, 95 % CI 0⋅41, 0⋅91) was associated with the lower odds of MAFLD. Our findings found that high intake of copper and adequate intake of iron were associated with MAFLD, which may provide guidance for the management of MAFLD.

Abstract
Objective The purpose of this investigation was to elucidate the relationship between the zinc and iron intake and the advancement of subchondral sclerosis among patients with osteoarthritis (OA). The goal was to establish personalized, nutritionally-informed strategies designed to retard the progression of subchondral sclerosis and conserve joint structure. Methods For the purposes of this research, we derived data from the Bone Ancillary Study (BAS), a constituent study of the Osteoarthritis Initiative (OAI). The intake of zinc and iron was evaluated via a food frequency questionnaire. Magnetic Resonance Imaging trabecular morphometry was employed to ascertain the microarchitecture of the subchondral bone. For the analysis of collected data, we employed logistic regression along with generalized additive models (GAMs). Results The participant cohort was comprised of 474 OA patients (216 females, 258 males, mean [SD] age 64.1[9.2]). Notably, an increment in zinc consumption was linked with a significantly reduced likelihood of deterioration in Tb.N (OR = 0.967, 95 % CI, 0.939-0.996, P-value = 0.026), Tb.Th (OR = 0.958, 95 % CI, 0.929-0.989, P-value = 0.008), and Tb.Sp (OR = 0.967, 95 % CI, 0.939-0.996, P-value = 0.013). An elevation in iron intake seemed to enhance the risk of subchondral sclerosis, as indicated by the GAM. Subgroup analysis revealed an interaction between the effectiveness of zinc intake and factors such as gender, age, radiographic severity, and macronutrient consumption. An increased intake of calcium amplified the beneficial impact of zinc on subchondral sclerosis. Conclusions Our findings indicate a positive association between elevated zinc intake and a slowdown in the progression of subchondral sclerosis in OA patients, notably among females, middle-aged individuals, and those with higher calcium and magnesium intake. Conversely, a higher iron intake might intensify subchondral sclerosis. These results suggest that personalized, diet-based interventions focusing on zinc consumption, in tandem with adequate calcium intake, could potentially decelerate the progression of subchondral sclerosis in individuals afflicted with OA.

Abstract
BACKGROUND Anemia is still one of the major public health problems in many developing countries including Ethiopia. Thus, this study aimed to assess individual and contextual-level factors associated with iron-folic acid supplement intake during pregnancy in Ethiopia. METHODS A secondary analysis was done on the 2019 mini-Ethiopian Demographic and Health Survey (EDHS) dataset. A total of 3,927 pregnant women who gave birth five years before the survey were included in the analysis. Multi-level mixed-effect logistic regression analysis was done by STATA/SE version 14.0 to identify individual and contextual-level factors. Adjusted Odds Ratio (AOR) with 95% Confidence Interval (CI) was used to show the strength and direction of the association. The level of statistical significance was declared at a P value less than 0.05. RESULTS Those primary educated [AOR = 1.83, 95% CI: (1.24, 2.74)], secondary educated [AOR = 2.75, 95% CI: (1.57, 4.824)], women who had greater than 5 living children [AOR = 2.02, 95% CI: (1.25, 3.27)], women who had ANC visit [AOR = 21.26, 95% CI: (13.56, 33.32)] and women who lived in a cluster with high proportion of women had ANC visit [AOR = 1.72, 95% CI: (1.17, 2.54)] and women who lived in Somali [AOR = 0.44 0.73, 95% CI: (0.22, 0.87)] were significantly associated with iron-folic acid intake during pregnancy. CONCLUSIONS Both individual and contextual-level factors were significantly associated with iron-folic acid intake during pregnancy. From individual-level factors: education status of women, the total numbers of living children, and ANC follow-up are significant and from contextual-level factors: region and living in a high proportion of women who had ANC follow-up were found to have a statistically significant association. Promoting women's education and maternal health services like ANC and intervention targeting the Somali region would be the recalled area of the government.

Abstract
BACKGROUND The role of iron biomarkers and iron intake in the susceptibility to lung cancer is unclear. The purpose of this study was to conduct a systematic review and meta-analysis, to assess the relationship between iron levels in the body or iron intake and the risk of lung cancer. METHOD This review is registered with PROSPERO (number CRD 42020199776). PubMed, Web of Science, Scopus, Embase and Cochrane were used to search for studies assessing the relationship between iron and lung cancer, up to July 15, 2021. Qualitative and quantitative analysis was carried out to determine if there was a correlation between iron biomarkers/intakes and the risk of lung cancer. RESULT Twenty articles were included. Pooled analyses demonstrated that serum ferritin concentrations and transferrin saturation (TSAT) were significantly higher in patients with lung cancer than in healthy controls (ferritin: standardized mean differences [SMD], 0.235, 95% confidence interval [CI], 0.129, 0.341, I2 = 32.1 %; TSAT: SMD, 0.07, 95 % CI, 0.018, 0.121, I2 = 0 %). In contrast, serum transferrin concentrations were significantly lower in patients with lung cancer than in healthy controls (SMD, -0.591, 95 % CI, -1.18, -0.003, I2 = 87.7 %). No significant effects of serum iron, lung tissue iron, bronchoalveolar lavage fluid (BALF) ferritin, or iron intake (total iron, dietary iron, heme iron, or non-heme iron) were found on lung cancer incidence. CONCLUSION Among the different iron biomarkers analyzed, a trend in association was only detected with serum ferritin, TSAT and transferrin concentration and no associations were found between iron intakes and the risk of lung cancer. However, more prospective studies are needed to strengthen the current evidence.

Abstract
The association between egg consumption and cognitive function is inclusive. We aimed to assess the association between egg consumption and cognitive function in Chinese adults and tested the interaction between egg consumption and Fe intake. The data used were from a nationwide sample (n 4852, age ≥ 55 years) from the China Health and Nutrition Survey between 1991 and 2006. Assessment of cognitive function was conducted in 1997, 2000, 2004 and 2006. Dietary egg intake was obtained by 24-h dietary recalls of 3 consecutive days during home visits between 1991 and 2006. Multivariable mixed linear regression and logistic regression were used. Egg intake was positively associated with global cognitive function. In fully adjusted models, across the quartiles of egg intake the regression coefficients were 0, 0·11 (95 % CI -0·28, 0·51), 0·79 (95 % CI 0·36, 1·22) and 0·92 (95 % CI 0·43, 1·41), respectively. There was a significant interaction between egg intake and Fe intake. The association between high egg intake and cognitive function was stronger among those with low Fe intake than those with high Fe intake. In addition, there was a significant interaction between egg consumption and sex, with the association mainly observed in women but not men. Furthermore, compared with non-consumers, those with higher egg consumption (Q4) had the OR of 0·93 (95 % CI 0·74, 1·19), 0·84 (95 % CI 0·69, 1·02) for self-reported poor memory and self-reported memory decline, respectively. Higher egg intake is associated with better cognition in Chinese adults among those with low Fe intake.

Abstract
Background Iron deficiency anemia (IDA) has been shown to be related to early childhood caries (ECC). However, data on the relationship, if any, between IDA-associated factors and ECC remain scant. This study aimed to explore the interplay between IDA-associated factors and ECC.
Methods This study randomly sampled a total of 1598 children in Qingdao city, and analyzed the severity of ECC using decayed-missing-filled teeth index, while the rate of caries was analyzed following the WHO recommendations. The correlation between IDA and ECC was analyzed by both the chi-square test and Mann–Whitney U test. In addition, we designed an electronic questionnaire and employed the disordered multi-classification logistic regression to interrogate the relationship between the IDA-associated factors and ECC. Results Children with IDA had higher rates and severe ECC than those without IDA (p < 0.001). Children who were breastfed until 2 years old had a higher risk of IDA and ECC, compared to those who were not {OR 3.453 (1.681–7.094)}. Compared with children who had no history of IDA at the age of 2 years or below, those with IDA history had a higher risk of IDA and ECC {OR 8.762 (3.648–21.041)}. In addition, children who had a maternal history of IDA at pregnancy were at a higher risk of IDA and ECC compared to those who had no IDA history at pregnancy {OR 4.913 (2.934–8.226)}. Our data showed that children from a family with an annual income lower than 50,000 Renminbi (RMB) had a higher risk of IDA and ECC compared to those with an annual family income higher than 200,000 RMB {OR 3.421 (1.505–7.775)}. On the other hand, compared with children taking iron supplements, children who did not were at a higher risk of ECC and IDA {OR 5.602 (1.858–16.896)}. Conclusion Factors such as low family income, history of IDA in children aged 2 years or younger, IDA history during pregnancy, children breastfed until 2 years old, and those not taking iron supplements were significantly associated with the occurrence of ECC and IDA.

Abstract
The study aims to analyze the correlation of helminthiasis, iron intake, and hemoglobin levels in pregnant women in the Public Health Center of Kemusu 2 Boyolali, Central Java, Indonesia. A cross-sectional research design was applied to 164 pregnant women who are in the second-third trimester and selected using simple random sampling. The Cyanmethemoglobin tool was utilized to measure the respondents' hemoglobin levels. The iron intake was obtained using the Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ). Data analysis applied the Pearson's correlation test. This study discovered that 12.2% of subjects are infected by Ascaris lumbricoides; 34.1% and 36.6% of the subjects suffer from iron intake deficiency and anemia. There is a correlation between helminthiasis, iron intake, and hemoglobin levels in pregnant women (p=.005 and p=.007). Nutrition program is still needed to prevent the helminthiasis, reduce the prevalence of anemia in pregnant women, and improve their iron intake through supplementation and nutrition education.

Abstract
PURPOSE To describe Australian pre-schooler dietary patterns and examine their associations with dietary iron intakes. METHODS Dietary data of children (n = 812, 2 to < 6 years old) from the 2011-12 National Nutrition and Physical Activity Survey were collected via two non-consecutive 24-h recalls and analysed using AUSNUT 2011-13. Usual food and nutrient intakes were estimated via Multiple Source Method. Principal component analysis was used to extract dietary patterns from 32 food groups. Associations between dietary patterns and energy-adjusted iron intakes were assessed using linear regression, accounting for the complex survey design. RESULTS Mean (SD) usual total dietary and haem iron intakes were 6.3 (1.9) and 0.5 (0.3) mg/day, respectively. Three dietary patterns were identified, explaining 14% of the variance. Pattern 1 (positive loadings for cheese, breads, fats and oils, and water) was positively associated with total dietary iron intakes (β = 0.08, 95% CI 0.01, 0.15). Pattern 3 (positive loadings for red meat, fortified fruit and vegetable products, and sauces and spreads) was negatively associated with total dietary iron (β = - 0.08, 95% CI - 0.14, - 0.01) and non-haem iron (β = - 0.09, 95% CI - 0.15, - 0.02) intakes. No dietary patterns were associated with haem iron intakes. CONCLUSIONS Three main patterns characterise Australian pre-schooler diets. The pattern with which dietary iron is positively associated is predominately characterised by non-haem iron sources and non-iron-fortified foods. Future research is required to estimate the iron bioavailability of Australian pre-schooler diets.

Abstract
BACKGROUND Iron has been shown to promote breast carcinogenesis in animal models through generation of oxidative stress and interaction with estrogen. Heme iron, which is found exclusively in animal-sourced foods, is suggested to have a more detrimental effect. Epidemiological evidence of the association between iron and breast cancer risk remains inconclusive and has not been comprehensively summarized. This systematic review and meta-analysis evaluated associations between both iron intake and body iron status and breast cancer risk. METHODS Four electronic databases (MEDLINE, EMBASE, CINAHL, and Scopus) were searched up to December 2018 for studies assessing iron intake and/or biomarkers of iron status in relation to breast cancer risk. Using random-effects meta-analyses, pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated comparing the highest vs. lowest category of each iron measure. Dose-response meta-analyses were also performed to investigate linear and nonlinear associations. RESULTS A total of 27 studies were included in the review, of which 23 were eligible for meta-analysis of one or more iron intake/status measures. Comparing the highest vs. lowest category, heme iron intake was significantly associated with increased breast cancer risk, with a pooled RR of 1.12 (95% CI: 1.04-1.22), whereas no associations were found for dietary (1.01, 95% CI: 0.89-1.15), supplemental (1.02, 95% CI: 0.91-1.13), or total (0.97, 95% CI: 0.82-1.14) iron intake. Associations of iron status indicators with breast cancer risk were generally in the positive direction; however, a significant pooled RR was found only for serum/plasma levels (highest vs. lowest) of iron (1.22, 95% CI: 1.01-1.47), but not for ferritin (1.13, 95% CI: 0.78-1.62), transferrin saturation (1.16, 95% CI: 0.91-1.47), or total iron-binding capacity (1.10, 95% CI: 0.97-1.25). In addition, a nonlinear dose-response was observed for heme iron intake and serum iron (both Pnonlinearity < 0.05). CONCLUSIONS Heme iron intake and serum iron levels may be positively associated with breast cancer risk. Although associations were modest, these findings may have public health implications given the widespread consumption of (heme) iron-rich foods. In light of methodological and research gaps identified, further research is warranted to better elucidate the relationship between iron and breast cancer risk.

Abstract
PURPOSE To estimate the prevalence of inadequate iron intakes and identify socio-demographic factors associated with iron intakes of Australian children aged 2-5 years. METHODS Data from the 2011-2012 National Nutrition and Physical Activity Survey component of the Australian Health Survey were analysed (n = 783, 2-5 years old). Dietary intake was assessed via two non-consecutive 24-h recalls. Prevalence of inadequate iron intake was estimated using the full probability approach after estimating the distribution of usual intakes with PC-SIDE. Associations between potential socio-demographic factors and energy-adjusted iron intakes were assessed via linear regression accounting for the complex survey design. RESULTS Mean (SD) iron intakes for pre-schoolers were 7.9 (1.9) mg/day and the prevalence of inadequate iron intake was 10.1% (95% CI 7.9%, 12.1%). Male sex (mean difference between boys and girls: - 0.22 (95% CI - 0.03, - 0.41) mg/day; p = 0.022) and age (each additional year was associated with 0.11 (95% CI - 0.22, - 0.00) mg/day lower iron intake; p = 0.048) were negatively associated with pre-schooler iron intakes. CONCLUSIONS This study provides current data relating to the iron nutrition of Australian pre-schoolers. Poor iron intakes continue to be a problem for 10% of Australian children beyond the second year of life, with iron intakes being lower for boys compared to girls and declining with age. Future research should examine strategies to improve iron intakes of young children, with a focus on promoting iron-rich food sources.

Abstract
Objectives National surveys consistently identify iron deficiency (ID) in US children between 1 and 3 years of age, when the brain is rapidly developing and vulnerable to the effects of ID. However, controversy remains as to how best to recognize and prevent ID in young children, in part because of the multiple potential etiologies. The objective of this project was to assess ID in children and identify potential individual dietary predictors of status. Methods We examined three biomarkers of ID [soluble transferrin receptor (sTfR) and serum ferritin (SF), and body iron (calculated from sTfR and SF)] against parent-provided dietary calcium and iron intake for eight-three 18-36 month old children from middle class families. Results Using literature-based cutoffs, fourteen children (16.9 %) had at least one indicator of ID: low SF(<10 μg/l, 7.2 %), negative body iron (<0 mg/kg, 7.2 %) or elevated sTfR (>8.4 μg/ml, 13.2 %). All children consumed more than the Dietary Reference Intake (DRI) Estimated Average Requirement of 3 mg/d iron. The mean iron intake of children identified with ID approximated the Recommended Dietary Allowance of 7 mg/d. Most children (81 %) consumed above the DRI Adequate Intake of 500 mg/d of calcium. Calcium intakes were generally high and predicted lower body iron (p = 0.0005), lower SF (p = 0.0086) and higher sTfR (p = 0.0176). Conclusions for Practice We found rates of ID similar to US national averages. Dietary calcium intake predicted lower iron status more than deficits in iron intake. Teaching parents to balance calcium and iron intake in toddlers could be a strategy to prevent ID.

Abstract
Fe deficiency remains the most common nutritional deficiency worldwide and young children are at particular risk. Preventative food-based strategies require knowledge of current intakes, sources of Fe, and factors associated with low Fe intakes; yet few data are available for Australian children under 2 years. This study's objectives were to determine intakes and food sources of Fe for Australian infants and toddlers and identify non-dietary factors associated with Fe intake. Dietary, anthropometric and socio-demographic data from the Melbourne Infant Feeding, Activity and Nutrition Trial Program were analysed for 485 infants (mean age: 9·1 (sd 1·2) months) and 423 toddlers (mean age: 19·6 (sd 2·6) months) and their mothers. Dietary intakes were assessed via 24-h recalls over 3 non-consecutive days. Prevalence of inadequate Fe intake was estimated using the full probability approach. Associations between potential non-dietary predictors (sex, breast-feeding status, age when introduced to solid foods, maternal age, maternal education, maternal employment status and mother's country of birth) and Fe intakes were assessed using linear regression. Mean Fe intakes were 9·1 (sd 4·3) mg/d for infants and 6·6 (sd 2·4) mg/d for toddlers. Our results showed that 32·6 % of infants and 18·6 % of toddlers had inadequate Fe intake. Main food sources of Fe were Fe-fortified infant formula and cereals for infants and toddlers, respectively. Female sex and current breast-feeding were negatively associated with infant Fe intakes. Introduction to solid foods at or later than 6 months was negatively associated with Fe intake in toddlers. These data may facilitate food-based interventions to improve Australian children's Fe intake levels.

Abstract
This study provides data on the total and haem iron contents in raw lean beef, chicken, lamb and pork meat samples. Total iron, expressed as mg/100g edible portion on fresh weight basis in raw lean beef (A-age), lamb, pork and chicken average 1.58, 1.64, 0.81 and 0.78, respectively. The haem iron content in beef (A-age), lamb, pork and chicken are 77%, 81%, 88% and 74% respectively of total iron. This has important dietary implications in calculating haem iron fractions of meat as this is higher than the common value used in the Monsen equation.

Abstract
Food-insecure pregnant females may be at greater risk of iron deficiency (ID) because nutrition needs increase and more resources are needed to secure food during pregnancy. This may result in a higher risk of infant low birth weight and possibly cognitive impairment in the neonate. The relationships of food insecurity and poverty income ratio (PIR) with iron intake and ID among pregnant females in the United States were investigated using National Health and Nutrition Examination Survey 1999-2010 data (n=1,045). Food security status was classified using the US Food Security Survey Module. One 24-hour dietary recall and a 30-day supplement recall were used to assess iron intake. Ferritin, soluble transferrin receptor, or total body iron classified ID. Difference of supplement intake prevalence, difference in mean iron intake, and association of ID and food security status or PIR were assessed using χ(2) analysis, Student t test, and logistic regression analysis (adjusted for age, race, survey year, PIR/food security status, education, parity, trimester, smoking, C-reactive protein level, and health insurance coverage), respectively. Mean dietary iron intake was similar among groups. Mean supplemental and total iron intake were lower, whereas odds of ID, classified by ferritin status, were 2.90 times higher for food-insecure pregnant females compared with food-secure pregnant females. Other indicators of ID were not associated with food security status. PIR was not associated with iron intake or ID. Food insecurity status may be a better indicator compared with income status to identify populations at whom to direct interventions aimed at improving access and education regarding iron-rich foods and supplements.

Abstract
BACKGROUND Some studies have shown that increased rate of iron stores even in a normal range may increase cardiovascular diseases (CVDs) in some individuals. Lipid disorders are also the risk factors for CVDs. Therefore, the question is whether or not iron store is correlated with lipid profile, this study evaluates the association between dietary iron, iron stores and serum lipid profiles. MATERIALS AND METHODS This cross-sectional study was done on 82 healthy university students and university staff females in Isfahan University of Medical Sciences who were in reproductive age and announced their readiness to participate in the study. Serum ferritin concentration, components of lipid profile, blood glucose, and insulin were measured in all the subjects. Dietary intake was assessed by semi-quantitative food frequency questionnaire. Data analysis was done through SPSS software, version 18. RESULTS Pearson correlation test showed a positive and significant correlation between serum ferritin concentration levels with triglyceride (r = 0.278; P = 0.006), total cholesterol (r = 0.267; P = 0.008), and blood glucose (r = 0.275; P = 0.006); however, the correlation between serum ferritin, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, and insulin was not significant. After adjustment of confounding factors, only the significant correlation occurred for blood glucose (P = 0.016). Before and after adjustment of confounding factors, there was no significant correlation between hemoglobin and hematocrit with concentration of lipid profile components, glucose and insulin. Before and after adjustment of confounding factors, there was no significant correlation between total amount of iron, heme iron, and non-heme dietary iron with concentration of lipid profile components, glucose and insulin. CONCLUSION According to the current study, serum ferritin is directly and significantly correlated with concentration of fasting blood glucose, which emphasized on the amount of iron store with blood glucose even in healthy people. The results of the present study indicate no significant correlation between iron store and dietary iron intake with lipid parameters and insulin. Conducting more extensive epidemiologic studies in men and other age groups is recommended.
