AbstractObjective:To examine the association between consumption of red and processed meat (RPM) and iron intakes and status in adults.Design:Further analysis of the Dietary and Nutritional Survey of British Adults, a cross-sectional study of 2197 adults aged 16–64 years carried out in 1986/7.Subjects and methods:Adults (836 men and 838 women) with serum ferritin measurements, who were not taking iron supplements, were classified into four groups according to RPM consumption (from 7-day weighed records). Iron absorbed was estimated from equations based on haem and non-haem iron and the influence of iron stores.Results:Women who ate least meat (<90gday-1) had three times the risk of a low iron intake (below the Lower Reference Nutrient Intake) compared with high consumers of RPM (>140gday-1). Men who ate no RPM also had a higher risk of low iron intake. Using an estimate of minimal values for iron losses, there was a twofold difference in the potential risk of negative iron balance between women non-RPM consumers and high RPM consumers. Status measurements indicated that, among women, anaemia was least prevalent (6%) among high consumers compared with 12–14% among average RPM consumers. Inverse trends were also observed for serum ferritin in both sexes.Conclusions:Low consumption of RPM has implications for iron intakes and iron status in men and women, since the risk of negative iron balance and its consequences are increased. Dietary messages must consider these implications and provide appropriate advice.

Introduction: Over the last decade, the possible impact of meat intake on overall cancer incidence and mortality has received considerable attention, and authorities have recommended decreasing consumption; however, the benefits of reducing meat consumption are small and uncertain. As such, individual decisions to reduce consumption are value- and preference-sensitive. Consequently, we undertook a pilot cross-sectional study to explore people’s values and preferences towards meat consumption in the face of cancer risk. Methods and analysis: The mixed-method pilot study included a quantitative questionnaire followed by qualitative evaluation to explore the dietary habits of 32 meat eaters, their reasons for eating meat, and willingness to change their meat consumption when faced with a potential risk reduction of cancer over a lifetime based on a systematic review and dose–response meta-analysis. We recruited a convenience sample of participants from two Canadian provinces: Nova Scotia and Prince Edward Island. This project was approved by the Research Ethics Board for Health Sciences research at Dalhousie University, Canada. Results: The average weekly consumption of red meat was 3.4 servings and the average weekly consumption of processed meat was 3 servings. The determinants that influenced meat intake were similar for both red and processed meat. Taste, cost, and family preferences were the three most commonly cited factors impacting red meat intake. Taste, cost, and (lack of) cooking time were the three most commonly cited factors impacting processed meat intake. None of the participants were willing to eliminate red or processed meat from their diet. About half of participants were willing to potentially reduce their meat consumption, with one third definitely willing to reduce their consumption. Strengths and limitations: This study is the first that we are aware of to share data with participants on the association of red meat and processed meat consumption and the risk of cancer mortality and cancer incidence, including the certainty of evidence for the risk reduction. The limitations of this study include its small sample size and its limited geographic sampling. Conclusions: When presented explicit information about the small uncertain cancer risk associated with red and processed meat consumption, study participants were unwilling to eliminate meat, while about one-third were willing to reduce their meat intake.

Close economic ties encourage production and trade of meat between Canada, Mexico, and the US. Understanding the patterns of red and processed meat consumption in North America may inform policies designed to reduce meat consumption and bolster environmental and public health efforts across the continent. We used nationally-representative cross-sectional survey data to analyze consumption of unprocessed red meat; processed meat; and total red and processed meat. Generalized linear models were used to separately estimate probability of consumption and adjusted mean intake. Prevalence of total meat consumers was higher in the US (73.6, 95% CI: 72.3–74.8%) than in Canada (65.6, 63.9–67.2%) or Mexico (62.7, 58.1–67.2%). Men were more likely to consume unprocessed red, processed, and total meat, and had larger estimated intakes. In Mexico, high wealth individuals were more likely to consume all three categories of meat. In the US and Canada, those with high education were less likely to consume total and processed meat. Estimated mean intake of unprocessed red, processed, and total meat did not differ across sociodemographic strata. Overall consumption of red and processed meat remains high in North America. Policies to reduce meat consumption are appropriate for all three countries.

Abstract Background Iron deficiency is a leading cause of anemia among pregnant women in Uganda. However, due to the high cost of biochemical tests required to determine iron deficiency, the prevalence and factors associated with iron deficiency remain largely unstudied in our setting. Therefore, this study aimed at determining the prevalence of iron deficiency and its associated factors among pregnant women attending an antenatal clinic, Lira District-Uganda.Methods A cross-sectional study was conducted among 320 pregnant women attending an antenatal clinic at Lira Regional Referral Hospital. Maternal serum ferritin was used as a measure of iron deficiency and was determined using a Cobas 6000 Automated Analyzer. Iron deficiency was based on serum ferritin of <30 μg/L. A semi-structured questionnaire was used to obtain the characteristics of the study participants. Binary and multivariate logistic regression were performed to identify the associated factors.Results The prevalence of iron deficiency was 45%. Non-adherence to iron supplements (AOR: 2.05 95% CI: 1.02-4.12) & third trimester pregnancy (AOR: 1.88 95% CI: 1.20-2.94) were significantly associated with iron deficiency during pregnancy.Conclusion Nearly 5 in 10 of the participants had iron deficiency. Iron deficiency during pregnancy was associated with non-adherence to iron supplements and being in the third trimester of pregnancy. Midwives should encourage pregnant women to adhere to iron supplements during pregnancy especially pregnant women who are in the third trimester.

Background: Dietary iron intake and serum ferritin in relation to severe headache or migraine remain largely unknown. Therefore, we investigated the associations between dietary iron intake and serum ferritin with severe headache or migraine among American adults.Methods: This cross-sectional study included 7,880 adults (≥20 years) from the National Health and Nutrition Examination Surveys (NHANES) of America from 1999 to 2004. We performed multivariable logistic regression and restricted cubic spline (RCS) regression to assess the association of dietary iron and serum ferritin with severe headache or migraine.Results: Most women aged 20–50 years consumed less dietary iron than their recommended dietary allowances. Dietary iron intake was inversely associated with severe headache or migraine in women aged 20–50 years. For women over 50 years, serum ferritin was negatively associated with severe headache or migraine. For men, there was no significant relationship between dietary iron and serum ferritin, and severe headache or migraine.Conclusions: Dietary iron intake has different effects on migraine in women of different ages, and this different effect may be due to age-related menstrual changes. Women aged 20–50 years should have a higher awareness of RDA and increase their dietary iron intake if needed, which may play an important role in preventing severe headache or migraine. Higher serum ferritin levels in women aged 50 and above may have a protective effect against migraine.

Introduction: Iron is essential for child’s development and growth. Children’s iron requirements are secured from daily food intake that might be affected by Covid-19 pandemic. This study aims to determine iron intake and its relationship with ferritin and hemoglobin levels as indicators of iron status among children in Jakarta.Method: This cross-sectional study was conducted in Kampung Melayu, Jakarta from September to October 2020. Seventy seven healthy children aged 24–36 months were taken using total population sampling method. Interviews were conducted to obtain characteristics data and iron intake using a semi-quantitative-food frequency questionnaire (SQ-FFQ). Blood tests are performed to check the levels of ferritin (controlled by hs-CRP value), and hemoglobin.Pearson’s/Spearman’s correlation test was performed using SPSS version 20.0. Result: Median of iron intake was 9.6 (1.5–40,7) mg/day, in which 33.8% of subjects was below the Indonesian Recommended Dietary Allowance (RDA) recommendation. The median ferritin value was 18.1 (1.4–91.1) 𝜇g/L and the hemoglobin was 11.8 (6.6–15.2) g/dL, in which 40.3% and 27.3% subjects with iron insufficient-deficient and anemia, respectively. There were  positive correlations between iron intake and ferritin (r = 0.328, p = 0.002) and iron intake and hemoglobin (r = 0.308, p = 0.003). A strong positive correlation was found between ferritin and hemoglobin (r = 0.769, p < 0.001).Conclusion: Iron intake of children aged 24–36 months had a weak positive correlation with ferritin and hemoglobin level. Keywords: children 24–36 months, ferritin, hemoglobin, iron intake, Jakarta

This study assessed serum ferritin, hemoglobin, and hematocrit among 107 physically active young people 9 to 18 years of age. Tanner stage (TS) of puberty was assessed and subjects were categorized as prepubertal (TS 1), midpubertal (TS 2, 3, and 4, excluding menarcheal females) and going through their rapid growth phase, or late pubertal (TS 5 and menarcheal females) and having completed their rapid growth phase. Midpubertal females had a lower hematocrit than late pubertal females, but there were no significant differences in serum ferritin or hemoglobin between pubertal groups. Late pubertal males had hemoglobin and hematocrit values that were higher than among prepubertal males, but serum ferritin did not differ. At late puberty the males had significantly higher serum ferritin, hemoglobin, and hematocrit compared with late pubertal females, and females in late puberty were more likely to have marginal iron stores compared with males at the same stage of pubertal development. Midpubertal and late pubertal females reported a diet low in absorbed iron, which could contribute to their poorer iron status.

Abstract To determine how best to assess iron status, I studied 12 young renal patients (ages 5.5 to 20 years) undergoing regular hemodialysis treatments. Iron balance was estimated by monitoring iron loss ascribable to blood loss during dialysis and diagnostic testing, and iron intake in the form of oral and intravenous iron supplements and blood transfusions. Traditional methods of evaluating iron status--measurement of hemoglobin, erythrocyte indices, reticulocyte count, iron, and transferrin--were compared with measurement of serum ferritin. The serum ferritin measurements provided superior information. In three cases this method was superior to visual assessment of bone marrow stained for iron.

BACKGROUND: Iron deficiency (ID) anemia remains a common cause of anemia in young children. However, the more significant than anemia itself is the ID without anemia that also adversely affect neurocognitive development and unfortunately some of these effects may be irreversible. AIM: This study is a cross-sectional study aimed to asses iron status in preschool children with normal hemoglobin (Hgb) level attending Assiut University Children Hospital. METHODS: The cross-sectional study including 68 apparently healthy children aged 1–6 years old during the period from January 1, 2015 to June 30, 2015, They were subjected to detailed history, physical examination, and the following laboratory investigations: Complete blood count, Serum iron, Total Iron Binding Capacity, Serum ferritin, and Transferrin saturation. RESULTS: Low serum ferritin and low transferrin saturation were detected in 41.2% and 47% respectively of our studied children who have normal Hgb levels. CONCLUSION: Normal Hgb doesn’t exclude ID that should be screened in healthy children to prevent the possible long-term effects of ID on their cognation and mental development.

ABSTRACT Background Acylcarnitines (ACs) play a major role in fatty acid metabolism and are potential markers of metabolic dysfunction with higher blood concentrations reported in obese and diabetic individuals. Diet, and in particular red and processed meat intake, has been shown to influence AC concentrations but data on the effect of meat consumption on AC concentrations is limited. Objectives To investigate the effect of red and processed meat intake on AC concentrations in plasma and urine using a randomized controlled trial with replication in an observational cohort. Methods In the randomized crossover trial, 12 volunteers successively consumed 2 different diets containing either pork or tofu for 3 d each. A panel of 44 ACs including several oxidized ACs was analyzed by LC-MS in plasma and urine samples collected after the 3-d period. ACs that were associated with pork intake were then measured in urine (n = 474) and serum samples (n = 451) from the European Prospective Investigation into Cancer and nutrition (EPIC) study and tested for associations with habitual red and processed meat intake derived from dietary questionnaires. Results In urine samples from the intervention study, pork intake was positively associated with concentrations of 18 short- and medium-chain ACs. Eleven of these were also positively associated with habitual red and processed meat intake in the EPIC cross-sectional study. In blood, C18:0 was positively associated with red meat intake in both the intervention study (q = 0.004, Student's t-test) and the cross-sectional study (q = 0.033, linear regression). Conclusions AC concentrations in urine and blood were associated with red meat intake in both a highly controlled intervention study and in subjects of a cross-sectional study. Our data on the role of meat intake on this important pathway of fatty acid and energy metabolism may help understanding the role of red meat consumption in the etiology of some chronic diseases. This trial was registered at Clinicaltrials.gov as NCT03354130.

Objectives: This study investigated the relationship of socioeconomic status (SES), diet quality and overweight and obesity in adults aged 40–59 years in Inner Mongolia.Methods: This cross-sectional study was based on the survey of Chronic Disease and Nutrition Monitoring in Adults in Inner Mongolia in 2015. Diet quality was evaluated by the Alternate Mediterranean Diet score (aMeds). SES was measured by household annual income. Generalized estimating equations and path analysis were performed to determine the association of SES, diet quality and overweight and obesity.Results: Among participants, 63.0% had overweight and obesity. In high SES group, 66.4% had overweight and obesity. Higher SES was associated with a higher risk of overweight and obesity (OR = 1.352, 95%CI: 1.020–1.793). And higher aMeds was associated with a lower risk of overweight and obesity (OR = 0.597, 95%CI: 0.419–0.851). There was a positive correlation between SES and the intake of red and processed meat (r = 0.132, p &lt; 0.05). Higher intake of red and processed meat was associated with lower diet quality (β = −0.34). And lower diet quality was associated with a higher risk of overweight and obesity (β = −0.10).Conclusion: In Inner Mongolia, during the period of economic transition, people aged 40–59 years in high SES had poor diet quality, which was related to a higher risk of overweight and obesity.
