Clinical evidence of low-calorie and ketogenic nutrological therapy before, during and after bariatric surgery: a systematic review

Introduction: Obesity is a multifactorial disease that causes serious comorbidities. There are more than 2.2 billion overweight and obese people in the world. Obese patients tend to be predisposed to micronutrient deficiency even before bariatric surgery, therefore, it is imperative to supplement nutrients orally, enterally, or parenterally, according to the indications of each patient. Objective: It was highlighted the importance of low-calorie and ketogenic nutritional therapy before, during, and after bariatric surgery through the systematic analysis of clinical studies. Methods: The systematic review rules of the PRISMA Platform were followed. The search was conducted from June to July 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: 119 articles were found. A total of 40 articles were fully evaluated and 34 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 23 studies with a high risk of bias and 27 that did not meet GRADE and AMSTAR-2. Most studies presented homogeneity in their results, with X2=76.5%>50%. It was concluded that nutrological therapy strategies could represent a possible alternative to other methodologies, especially when it is recommended to improve patient adherence to following the prescribed diet before bariatric surgery. Weight loss induced by the ketogenic diet before bariatric surgery has beneficial effects on reducing liver volume, metabolic profile, and intra- and postoperative complications. Knowledge of the type of bariatric surgery performed and an understanding of its anatomy and physiology are useful to provide optimal care to patients, especially in nutritional complications. Nutritional deficiencies and metabolic disorders result from “malabsorption” procedures such as RYGB. Immediate administration of thiamine is essential. Dextrose should be avoided in intravenous hydration until thiamine is adequately replaced. For all bariatric patients, a protein intake of 60-70 g/d and a multivitamin with iron and vitamin B12 supplementation is recommended. Daily calcium and vitamin D supplementation is also encouraged. In addition, serum micronutrient levels should be monitored regularly and additional supplementation should be prescribed as indicated.

Use of multiple micronutrient supplementation integrated into routine antenatal care: A discussion of research priorities.

Optimal maternal nutrition, including adequate intake and status of essential micronutrients, is important for the health of women and developing infants. Currently, the World Health Organization (WHO) Antenatal care recommendations for a positive pregnancy experience recommend daily iron and folic acid (IFA) supplementation as the standard of care. The use of multiple micronutrient supplements (MMSs) is recommended in the context of rigorous research as more evidence was needed regarding the impact of switching from IFA supplements to MMS, including evaluation of critical clinical maternal and perinatal outcomes, acceptability, feasibility, sustainability, equity and cost-effectiveness. WHO convened a technical consultation of key stakeholders to discuss research priorities with the objective of providing guidance and clarity to donors, implementers and researchers about this recommendation. The overarching principles of the research agenda include the use of clinical indicators and impact measures that are applicable across studies and settings and the inclusion of outcomes that are important to women. Future studies should consider using standardized protocols based on current best practices to measure critical outcomes such as gestational age (GA) and birthweight (BW) in studies. As GA and BW are influenced by multiple factors, more research is needed to understand the biological impact pathways, and how initiation and considerations for timing of MMS influence these outcomes. A set of core clinical indicators was agreed upon during the technical consultation. For implementation research, the Evidence-to-Decision framework was used as a resource for discussing components of implementation research. The implementation research questions, key indicators and performance measures will depend on country-specific context and bottlenecks that require further research and improved solutions to enable the successful implementation of iron-containing supplements.

Intravenous versus oral iron for anaemia among pregnant women in Nigeria (IVON): an open-label, randomised controlled trial

Oral iron for anaemia in pregnancy is often not well tolerated, with poor adherence. Iron administered intravenously might address these tolerance and adherence issues. We investigated the effectiveness and safety of intravenous ferric carboxymaltose versus oral ferrous sulphate on anaemia and iron deficiency among pregnant women in Nigeria. We did a multicentre, open-label, parallel, randomised controlled trial of pregnant women (aged 15-49 years) with haemoglobin (Hb) concentrations of less than 10 g/dL at 20-32 weeks' gestation from 11 primary, secondary, or tertiary health facilities in Nigeria (five in Lagos and six in Kano). Exclusion criteria included vaginal bleeding, blood transfusion or major surgery within the past 3 months, symptomatic anaemia, anaemia known to be unrelated to iron deficiency, clinically confirmed malabsorption syndrome, previous hypersensitivity to any form of iron, pre-existing maternal depression or other major psychiatric illness, immune-related diseases, such as systemic lupus erythematosus or rheumatoid arthritis, or severe allergic reactions. Participants were randomly assigned (1:1) by nurses and doctors using a web-based randomisation service to either receive a single dose of intravenous ferric carboxymaltose (20 mg/kg to a maximum of 1000 mg) or oral ferrous sulphate (200 mg; 65 mg elemental iron) three times daily until 6 weeks postpartum. The study was primarily unmasked. Primary outcomes were maternal anaemia (Hb <11 g/dL) at 36 weeks' gestation and preterm birth at before 37 weeks' gestation, with analysis by intention to treat in participants with available data. This study was registered at the ISRCTN registry on Dec 10, 2020 (ISRCTN63484804) and on ClinicalTrials.gov (NCT04976179) on April 7, 2021. Between Aug 10, 2021, and Dec 15, 2022, 13 724 pregnant women were screened for eligibility. 12 668 were excluded due to ineligibility for inclusion, and 1056 provided consent to participate and were randomly assigned to either the intravenous or oral administration groups. 527 were assigned to the intravenous ferric carboxymaltose group and 529 were assigned to the oral ferrous sulphate group. 518 in the intravenous group were assessed at 36 weeks' gestational age and after 518 deliveries, and 511 completed the 6 weeks postpartum visit. 513 in the oral ferrous sulphate group were assessed at 36 weeks' gestational age and after 512 deliveries, and 501 completed the 6 weeks postpartum visit. No significant difference was found in anaemia at 36 weeks (299 [58%] of 517 in the intravenous group vs 305 [61%] of 503 in the oral group; risk ratio 0·95, 95% CI 0·85-1·06; p=0·36), nor in preterm birth (73 [14%] of 518 vs 77 [15%] of 513; 0·94, 0·70-1·26; p=0·66). There were no significant differences in adverse events. The most common adverse events were diarrhoea (in six participants) and vomiting (in three participants) in the oral group and fatigue (in two participants) and headache (in two participants) in the intravenous group. Although the effect on overall anaemia did not differ, intravenous iron reduced the prevalence of iron deficiency to a greater extent than oral iron and was considered to be safe. We recommend that intravenous iron be considered for anaemic pregnant women in Nigeria and similar settings. Bill & Melinda Gates Foundation.

Comparison of the Anaemia and Transfusion Rates of Pregnant Women Treated with Intravenous versus Oral Iron in the Third Trimester.

To evaluate and compare the blood transfusion requirements during delivery in third-trimester pregnant women with iron deficiency anaemia (IDA) who were treated with intravenous (IV) ferric carboxymaltose (FCM) versus those treated with oral iron supplementation. Comparative study. Place and Duration of the Study: Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkiye, from January 2017 to December 2022. Pregnant women with haemoglobin (Hb) levels <10 g/dL in their third trimester were included. One group (n = 50) received IV FCM, while the other group (n = 96) received oral iron therapy. Key outcome measures included Hb levels at delivery and the need for a postpartum blood transfusion. Inclusion criteria were third-trimester pregnancy with IDA, and exclusion criteria included haematological or chronic systemic diseases and high-risk pregnancies. The mean initial Hb levels in the third trimester of pregnancy in the FCM group and oral iron group were 8.31 ± 0.96 g/dL and 9.29 ± 1.20 g/dL, respectively (p <0.001). The mean Hb levels in the delivery room were 11.09 ± 1.38 and 9.44 ± 1.16 g/dL, respectively (p <0.001). The rates of postpartum erythrocyte transfusion requirement were 6% (n = 3) and 18.75% (n = 18), respectively (p = 0.037). IV FCM administration to pregnant patients with IDA during the third trimester was found to be more effective than oral iron treatment in reducing blood transfusion rates.

Multidisciplinary care to optimise pregnancy outcomes among Jehovah’s Witness: Case series over fifteen years in a tertiary teaching hospital

ObjectiveTo assess the obstetric and neonatal outcomes of Jehovah’s Witness (JW) mothers and the willingness to accept blood products after multidisciplinary management. Study DesignA retrospective case-control study was conducted at Queen Mary Hospital from 2005 to 2020. Delivery records of pregnant women who identified themselves as JW were reviewed. The immediate next age-matched non-JW patient in the booking register was assigned as control. ResultsA total of 96 subjects were identified within the study period (48 JW and 48 non-JW age-matched patients). The haemoglobin levels of JW and non-JW were similar at booking, 28 weeks of gestation, pre-delivery and postnatal day 2. JW mothers were more likely to receive iron supplements in the antenatal period than the control group (27.1 % vs. 6.3 %, p = 0.01) despite the similar rate of antenatal anemia in both groups (4.2 % vs. 4.2 %, p = 1.00). There were no differences in mode of delivery, total blood loss at delivery, rate of primary postpartum haemorrhage, gestational age at delivery, birth weight, and Apgar score at 1 and 5 min between JW and non-JW. There were no maternal deaths, hysterectomy or admissions to the adult intensive care unit in either group. Six JW women accepted packed cell transfusion at the initial consultation and did not receive multidisciplinary care. The remaining 42 JW women had consultant obstetric and anesthesiologist review before delivery. After multidisciplinary consultation, two (4.8 %, 2/42) accepted blood transmission and 11 (26.2 %, 11/42) accepted some components of blood. The remaining 29 (69 %, 29/42) women refused all blood products. ConclusionJW patients who received multidisciplinary care achieved comparable pregnancy and neonatal outcomes to the normal population. Antenatal iron supplement was more common among pregnant JW despite the similar rate of antenatal anemia compared with the non-JW women. 12.5% of JW women agreed packed cell transfusion at the initial consultation and a further 27.1% of JW women agreed to some forms of blood products after multidisciplinary counseling.

Prevalence, Incidence, and Risk Factors of Hypothyroidism in Adult Residents of Yazd Greater Area, 2015-2021: Results of Yazd Health Study.

Any abnormal change in thyroid hormone levels leads to thyroid disorders, including hyperthyroidism, hypothyroidism, goiter, and so on. Recent studies have reported an increasing prevalence and incidence of thyroid disorders worldwide. This study aims to determine the hypothyroid prevalence, incidence, and risk factors related to this disorder. Data from a comprehensive prospective cohort study, collected from a population of 10,000 Yazd (Iran) individuals over a period of 6 years (2015-2021) was analyzed. Physicians diagnosed hypothyroidism and reported it. Data processing and preparation were performed using SQL18 and Excel, while STATA17 and SPSS22 software were employed for data analysis. Descriptive statistics, logistic regression, and Chi-square tests were conducted at a significance level of 0.05. The prevalence of hypothyroidism was found to be 93/1000, and the incidence was 15/1000 of the population, respectively. Women had five folds more chance of hypothyroidism (adjusted OR=5.31, 95% CI=3.06-9.19 vs. unadjusted OR=6.28, 95% CI=3.90-10.12), and they usually developed it between the ages of 30 and 39. Eating less (iodized) salt also increased the risk of hypothyroidism (unadjusted OR=1.47, 95% CI=1.02-2.11). Iron supplementation (unadjusted OR=2.09, 95% CI=1.26-3.48) was identified as one of the significant risk factors. Based on our findings in the unadjusted model, tooth brushing once or twice a day increases the chance of hypothyroidism (OR=1.89, P=0.008, and OR=2.12, P=0.016, respectively). Tobacco smoking (unadjusted OR=0.29, 95% CI=0.107-0.786) was also among the factors that need further investigation. The increasing trend of hypothyroidism is concerning in our population. The high prevalence, particularly among women of childbearing age, is notable.

Post-transplant renal anemia: a call to action from a national study in routine clinical practice.

Post-transplant anemia is a prevalent yet often overlooked condition that poses significant risks. Current guidelines consider the same treatment recommendations and goals for these patients as for chronic kidney disease patients not on dialysis. Previous reports demonstrated a lack of awareness and suboptimal management, indicating a pressing need for improvement. We therefore wanted to update the information on post-transplant anemia. We aimed to describe the present state of anemia management, goals and adherence to guidelines within a representative sample of the kidney transplant (KTx) population. We designed a retrospective nationwide multicenter study including outpatients from eight KTx hospitals. Nephrologists gathered data from electronic medical records encompassing demographics, comorbidities, KTx characteristics and immunosuppressive therapy, and information pertaining to anemia management (laboratory values, previously prescribed treatments and subsequent adjustments). The European statement on the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines was the reference for definitions, drug prescriptions and targets. Anemia occurring within the initial 6 months post-transplantation was classified as early onset. We included 297 patients with post-transplant anemia aged 62.8 years (standard deviation 13.6), 60% of whom were male. They had received a graft from cardiac death or brain death donors (61.6% and 31.1%, respectively) a median of 2.5 years (0.5-8.7) before. Among them 77% (n=228) were classified as having late post-transplant anemia, characterized by a higher prevalence of microcytic and iron deficiency anemia. A total of 158 patients were on erythropoietic-stimulating agents (ESAs) treatment, yet surprisingly 110 of them lacked iron supplementation. Notably, 44 patients had an indication for iron supplementation and among them, 30 exhibited absolute iron deficiency. Out of the 158 patients receiving ESAs, only 39 surpassed the limit for the ESA resistance index, indicating poor response. This resistance was more frequent among patients with early post-transplant anemia (26.1% vs 9.2%). We have identified iron profile, early post-transplant anemia and estimated glomerular filtration rate as factors associated with the highest risk of resistance. We found that hemoglobin targets are individualized upwards in post-transplant anemia. In this setting, iron therapy continues to be underutilized, especially intravenous, and iron deficiency and prior events (blood transfusion or hospital admission) explain most of the hyporesponsiveness to ESA. This highlights missed opportunities for precise prescription targeting and adherence to established guidelines, suggesting a need for improved management strategies in post-transplant anemia patients.

Associations of pregnancy dietary quality and diversity with childhood celiac disease

Background and objectiveHigh gluten and low dietary fiber in pregnancy intake is associated with an increased risk of celiac disease in the child. Early life higher dietary quality is suggested to reduce the subsequent risk of celiac disease. The aim was to investigate associations of pregnancy dietary quality and diversity with child risk of celiac disease (CeD). MethodsIn The Norwegian Mother, Father and Child Cohort Study, 85,122 mother-child pairs had available data from a validated pregnancy food frequency questionnaire. Pregnancy dietary quality and diversity were estimated by a Pregnancy Healthy Eating Index, (mean 99.3, SD 9.9, range 48.8-128.3), and a Diet Diversity Score (mean 7.0, SD 1.0, range 1.6-9.8), respectively. Child CeD was captured by >2 diagnostic codes in the Norwegian Patient Registry. Logistic regression was used to estimate associations between pregnancy dietary quality, diversity and child CeD, adjusted for socio-economic factors and parents CeD (adjusted odds ratio [aOR], 95% confidence intervals [CI]). CeD-susceptible HLA haplotypes (DQ2/DQ8) were present in 30,718 (45.5%). ResultsUp to mean age 16.0 (SD 1.8, 12.4-19.8) years, 1,363 (1.6%) children were diagnosed with CeD. Lower as well as higher pregnancy dietary quality associated with a reduced risk of CeD in the child (<5th percentile aOR=0.67, 95%CI 0.48-0.93, >95th percentile aOR=0.71, 95%CI 0.52-0.98, respectively, non-linear squared term p= 0.011). Analyses on genetically susceptible children, adjustments for pregnancy iron supplementation, gluten, and dietary fiber intake, and child early life dietary quality, gluten intake and iron supplementation, supported the finding. Pregnancy dietary diversity was not associated with child CeD (aOR=1.00, 95%CI 0.94-1.07/score) ConclusionsIn this population-based study, lower as well as higher pregnancy dietary quality associated with a reduced risk of CeD diagnosis in the child. In contrast, no such association was observed with maternal dietary diversity.

Pil-Pintar Intervention Reduce Anemia among Young Teen Girls: A Pilot Study

Background: Iron deficiency anemia and low adherence to take iron tablets are prevalent issues among teenage school girls in Indonesia. To address this concern and encourage regular iron supplementation, the public health office of Sukoharjo Central Java Indonesia introduced a pil-pintar program, colloquially known as the “smart pill.” Aims: This study aimed to measure the increase in hemoglobin (Hb) levels and its correlation with nutrient intake related to Hb synthesis following the pil-pintar intervention. Methods: A quasi-experimental design with a one-group pre-posttest approach was performed involving 49 school teenage girls aged 12-15 years in a public school in Sukoharjo, Indonesia. Each student was given an iron sugar coat tablet containing 182 mg of ferrous-fumarate (equivalent to 60 mg elemental iron) and 0.400 mg of folic acid per tablet, called pil-pintar, once a week for 12 weeks. Results: A decrease in anemia prevalence by 24.4% and a notable increase in Hb levels by 1.0 mg/dL (p = 0.001) were observed in the 12 weeks of intervention. However, the study found no association between the nutrient intakes related to Hb production and the resulting Hb levels. Conclusion: The pil-pintar program effectively improved the hemoglobin levels of anemic teenage girls in the Sukoharjo district, Indonesia.

Association of Iron Therapy with Mortality in Patients with Acute Myocardial Infarction and Iron Deficiency.

Iron deficiency (ID) is common in patients with acute myocardial infarction (AMI). It is unknown whether patients with AMI combined with ID will benefit from iron supplementation therapy. This study aimed to assess the relationship between iron therapy and mortality in AMI patients. Retrospective analysis was performed in subjects screened from the Medical Information Mart in Intensive Care-IV database. The data were obtained from ICU patients admitted to Beth Israel Deaconess Medical Center between 2008 and 2019. The patients were divided into two groups according to iron treatment exposure. Propensityscorematching(PSM) was performed in the original cohort at a 1:1 ratio. Univariate and multivariate analyses were performed to adjust for confounding factors. The primary outcome was 28-day mortality. A total of 426 patients were included in this study. After 1:1 PSM, 208 patients were analyzed. Iron treatment was associated with a lower risk of 28-day mortality (9 deaths (8.65%) in the iron treatment group vs. 21 deaths (20.19%) in the non-iron treatment group; HR = 0.39; 95% CI = 0.17-0.89; p = 0.025) and in-hospital mortality (4 deaths (3.85%) in the iron treatment group vs. 12 deaths (11.54%) in the non-iron treatment group; OR, 0.15; 95% CI, 0.03-0.74; p = 0.029). Iron treatment was associated with reduced 28-day mortality in patients with AMI combined with ID. Iron treatment had no significant effect on the length of hospitalization or the length of ICU stay. Prospective studies are needed to verify this conclusion.

Enhancing screening for nutritional causes of anemia in hospitalized patients with cancer.

367 Background: Anemia in patients with cancer has been associated with lower quality of life, diminished performance status, and potentially even delays in chemotherapy. Multiple professional societies, including the NCCN and ESMO, recommend routine testing for iron deficiency and iron replacement if deficiency is identified. The aim of this quality improvement project was to increase testing for nutritional causes of anemia, especially iron deficiency, among patients admitted to the onco-hospitalist teaching service at MD Anderson Cancer Center. Methods: A process map was constructed to identify pitfalls with the current process for identifying and ordering testing for nutritional (iron, B12, and folate deficiency) causes of anemia. The primary intervention for our Plan-Do-Study-Act (PDSA) Cycle was creating and implementing an electronic medical record smart phrase to be included in each note prompting consideration of reversible causes of anemia and whether testing was ordered in the last 6 months or needs to be ordered. Education was also provided to residents regarding reversible causes of anemia and appropriate studies to order. Fliers describing the intervention and the recommended testing algorithm were placed in the resident workroom. A retrospective chart review of all patients admitted to the onco-hospitalist teaching service from August 2023 to February 2024 was employed to collect pre- and post-intervention data, and a run chart was created to plot rates of screening over time. Results: Of the pre-intervention cohort (n=263) from August to December 2023, 196 (74.5%) were identified as having anemia; of these patients, 109 (55.6%) underwent screening for nutritional causes of anemia during the admission. After our intervention was implemented, of all patients admitted to the service (n=186), a total of 156 (81.7%) were found to have anemia and 116 (74.3%) were screened for reversible causes of anemia. Almost all reversible causes of anemia were found to be secondary to iron deficiency. Conclusions: Our data shows that anemia is prevalent in our patient population yet inconsistently evaluated at baseline. At the same time, a combination of smart phrase utilization and education successfully increased rates of screening from 55.6% to 74.3% of patients admitted to the onco-hospitalist teaching service. One potential future endeavor is addition of a smartphrase to the admitting H&amp;P templates to prompt teams to consider reversible causes of anemia, especially iron deficiency, during the admission.

Bmp10 maintains cardiac function by regulating iron homeostasis

Heart disease remains the leading cause of death worldwide. Iron imbalance, whether deficiency or overload, contributes to heart failure. However, the molecular mechanisms governing iron homeostasis in the heart are poorly understood. Here, we demonstrate that mutation of bmp10, a heart-born morphogen crucial for embryonic heart development, results in severe anemia and cardiac hypertrophy in zebrafish. Initially, bmp10 deficiency causes cardiac iron deficiency, which later progresses to iron overload due to the dysregulated hepcidin/ferroportin axis in cardiac cells, leading to ferroptosis and heart failure. Early iron supplementation in bmp10−/− mutants rescues erythropoiesis, while iron chelation in juvenile fishes significantly alleviates cardiac hypertrophy. We further demonstrate that the interplay between HIF1α-driven hypoxic signaling and the IL6/p-STAT3 inflammatory pathways is critical for regulating cardiac iron metabolism. Our findings reveal BMP10 as a key regulator of iron homeostasis in the vertebrate heart and highlight the potential of targeting the BMP10-hepcidin-iron axis as a therapeutic strategy for iron-related cardiomyopathy.

High internal phase Pickering emulsions co-loaded with astaxanthin and ferrous gluconate improve iron deficiency anemia in mice and their applications in 3D printing

Iron deficiency anemia (IDA) is a prevalent and serious nutritional health issue that can be mitigated through dietary iron supplementation. However, only ferrous ions, prone to oxidation, can be absorbed in the gastrointestinal tract. In the current work, the effects of high internal phase Pickering emulsions (HIPPEs) co-loaded with astaxanthin (ASTA) and ferrous gluconate on Fe2+ oxidation, IDA management, and their 3D printing performance were investigated. The results demonstrated that the HIPPEs co-loaded with ASTA and ferrous gluconate effectively reduced the oxidation rate of Fe2+ during storage. Animal studies also revealed that HIPPE co-loaded with ASTA and ferrous gluconate had a therapeutic effect on IDA symptoms in mice. HIPPE co-loaded with ASTA and 400 mg/L ferrous gluconate demonstrated superior efficacy in restoring hemoglobin (Hb) levels, organ coefficients, and histological parameters in mice with IDA. Moreover, the evaluation of the adaptability of HIPPEs co-loaded with ASTA and ferrous gluconate for food 3D printing indicated a slight reduction in printing resolution. Overall printing performance was found to be acceptable and satisfactory. Co-loading ASTA and ferrous gluconate in HIPPEs offers an efficient way to address the oxidation challenge of ferrous ion supplementation, enabling customization and flexibility in the production of iron-fortified foods to mitigate IDA.

Dietary intake and diet quality of female and male NCAA Division I cross country runners from a single university

BackgroundCollegiate student-athletes have unique nutritional requirements to support their athletic performance and health. Few studies have comprehensively characterized the diets of NCAA Division I student-athletes. ObjectiveTo characterize dietary intake and diet quality during a competitive season in female and male NCAA Division I cross country student-athletes from a single university. MethodsFemales and males (n=14/sex) from the Florida State University cross country teams completed 9-d of food records across their competitive season. Nutrient intakes were compared to the Dietary Reference Intakes for the US population (e.g., RDAs) and athlete-specific guidelines. Diet quality was assessed according to the Dietary Guidelines for Americans (DGAs) using the 2020 Healthy Eating Index (HEI-2020). Total daily energy expenditure (TDEE) was estimated from training records. ResultsCarbohydrate intakes were below athlete guidelines in 43% of females (mean±SD, 5.67±1.16 g∙kg-1∙d-1) and 29% of males (4.95±1.05, p-sex=0.096). All participants met or exceeded athlete recommendations for protein (2.09±0.425 g∙kg-1∙d-1, 1.92±0.519, p-sex=0.36) and fat (32.8±5.1% kcal, 34.4±3.4%, p-sex=0.36). No participants met the RDA for vitamin D (5.14±1.78 μg/d, 4.91±3.24, p-sex=0.83). Only 79% of females and 36% of males met the RDA for calcium (1220±307 mg/d, 1010±296, p-sex=0.83). Most females (n=13) and males (n=11) consumed iron supplements where total intakes exceeded the UL (110±60.1 mg/d, 66.8±36.3, p-sex=0.029). HEI-2020 indicated poor adherence to the DGAs, with better diet quality in females (65.3±13.7) than males (50.6±10.1, p-sex=0.0034). Participants failed to meet guidelines for all HEI-2020 food group components except total protein foods. TDEE was greater in males and declined across the competitive season (p-sex<0.0001, p-time<0.0001, p-sex*time=0.25). ConclusionsNCAA Division I cross country student-athletes consumed inadequate carbohydrate, calcium, and vitamin D, but met or exceeded intake guidelines for protein, fat, and iron. Diet quality was poor; HEI-2020 component scores may indicate food groups to target to improve diet quality and intake of nutrients important to runners. ClinicalTrials.gov RegistrationNCT04079322.
