Ekwuocha I, Pereira A, Corvalán C, Michels KB, Gaskins AJ. Dietary Iron Intake in Relation to Age at Menarche: A Prospective Cohort Study in Chilean Girls. J Nutr 2023; 153:253-259. [PMID: 36913459 PMCID: PMC10196559 DOI: 10.1016/j.tjnut.2022.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 09/30/2022] [Accepted: 10/28/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Early onset of menarche is considered an important risk factor for a number of diseases in adulthood. Iron intake may be related to pubertal timing because of its role in childhood growth and reproductive function. OBJECTIVE We investigated the relation between dietary iron intake and age at menarche in a prospective cohort of Chilean girls. METHODS Overall, 602 Chilean girls were included in the Growth and Obesity Cohort Study, a longitudinal study that began in 2006 when the girls were 3-4 y old. Starting in 2013, diet was assessed every 6 mo through 24-h recall. The date of menarche was reported every 6 mo. Our analysis included 435 girls with prospective data on diet and age at menarche. We used a multivariable Cox proportional hazards regression model with restricted cubic splines to estimate HRs and 95% CIs for the association between cumulative mean iron intake and age at menarche. RESULTS Most girls (99.5%) attained menarche with a mean (standard deviation) age at menarche of 12.2 (0.9) y. The mean dietary iron intake was 13.5 (range: 4.0-30.6) mg/d. Only 3.7% of girls consumed below 8 mg/d, the RDA. After multivariable adjustment, cumulative mean iron intake had a nonlinear association with menarche (P-for-nonlinearity: 0.02). Iron intakes above the RDA, between 8 and 15 mg/d, were associated with progressively lower probability of earlier menarche. Above 15 mg/d, the HRs were imprecise but tended to approach the null as iron intake increased. This association was attenuated after adjusting for girls' BMI and height before menarche (P-for-nonlinearity: 0.11). CONCLUSION In Chilean girls, iron intake during late childhood, independent of body weight, was not an important determinant of menarche timing.

Addressing nutrient shortfalls in 1- to 5-year-old Irish children using diet modeling: development of a protocol for use in country-specific population health. Am J Clin Nutr 2021; 115:105-117. [PMID: 34718385 PMCID: PMC8755081 DOI: 10.1093/ajcn/nqab311] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 09/10/2021] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Dietary habits formed in early childhood can track into later life with important impacts on health. Food-based dietary guidelines (FBDGs) may have a role in improving population health but are lacking for young children. OBJECTIVES We aimed to establish a protocol for addressing nutrient shortfalls in 1- to 5-y-old children (12-60 mo) using diet modeling in a population-based sample. METHODS Secondary analysis of 2010-2011 Irish National Pre-School Nutrition Survey data (n = 500) was conducted to identify typical food consumption patterns in 1- to 5-y-olds. Nutrient intakes were assessed against dietary reference values [European Food Safety Authority (EFSA) and Institute of Medicine (IOM)]. To address nutrient shortfalls using diet modeling, 4-d food patterns were developed to assess different milk-feeding scenarios (human milk, whole or low-fat cow milk, and fortified milks) within energy requirement ranges aligned with the WHO growth standards. FBDGs to address nutrient shortfalls were established based on 120 food patterns. RESULTS Current mean dietary intakes for the majority of 1- to 5-y-olds failed to meet reference values (EFSA) for vitamin D (≤100%), vitamin E (≤88%), DHA (22:6n-3) + EPA (20:5n-3) (IOM; ≤82%), and fiber (≤63%), whereas free sugars intakes exceeded recommendations of <10% energy (E) for 48% of 1- to 3-y-olds and 75% of 4- to 5-y-olds. "Human milk + Cow milk" was the only milk-feeding scenario modeled that predicted sufficient DHA + EPA among 1- to 3-y-olds. Vitamin D shortfalls were not correctable in any milk-feeding scenario, even with supplementation (5 µg/d), apart from the "Follow-up Formula + Fortified drink" scenario in 1- to 3-y-olds (albeit free sugars intakes were estimated at 12%E compared with ≤5%E as provided by other scenarios). Iron and vitamin E shortfalls were most prevalent in scenarios for 1- to 3-y-olds at ≤25th growth percentile. CONCLUSIONS Using WHO growth standards and international reference values, this study provides a protocol for addressing nutrient shortfalls among 1- to 5-y-olds, which could be applied in country-specific population health.

Int J Nanomedicine 2020; 15:9657-9668. [PMID: 33299310 PMCID: PMC7721121 DOI: 10.2147/ijn.s275553] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 11/10/2020] [Indexed: 01/04/2023] Open
Abstract
Purpose To evaluate the effects of ZnO NPs on bone growth in rats and explore the possible mechanisms of action. Materials and Methods Three-week-old male rats received ultrapure water or 68, 203, and 610 mg/kg zinc oxide nanoparticles (ZnO NPs) for 28 days, orally. Results The high-dosage groups caused significant differences in weight growth rate, body length, and tibia length (P<0.05), all decreasing with increased ZnO NP dosage. There were no significant differences in body mass index (BMI) (P>0.05). The zinc concentration in liver and bone tissue increased significantly with increased ZnO NP dosage (P<0.05). Clearly increased aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were observed in the 610 mg/kg ZnO NP group (P>0.05), whereas alkaline phosphatase (ALP) increased in the 610 mg/kg ZnO NP group (P<0.05). Significant differences in insulin-like growth factor type 1 (IGF-1) levels and a decrease in calcium (Ca) levels were observed in 203 and 610 mg/kg ZnO NP groups (P<0.05). Phosphorus (P) levels increased and the Ca/P ratio decreased in the 610 mg/kg ZnO NP group (P<0.05). Micro-computed tomography (micro-CT) of the tibia demonstrated signs of osteoporosis, such as decreased bone density, little trabecular bone structure and reduced cortical bone thickness. Micro-CT data further demonstrated significantly decreased bone mineral density (BMD), trabecular number (Tb.N), and relative bone volume (BV/TV) with increasing dosage of ZnO NPs. Osteoprotegerin (OPG) expression and the ratio of OPG to receptor activator of nuclear factor-κB ligand (RANKL) were statistically lower in the 610 mg/kg ZnO NP group (P<0.05), whereas RANKL expression did not change significantly (P>0.05). Conclusion We infer that ZnO NPs affect bone growth in young rats directly or indirectly by altering IGF-1 levels. Overall, the results indicate that ZnO NPs promote osteoclast activity and increase bone loss through the OPG/RANK/RANKL/IGF-1 pathway.

Iron Content of Commercially Available Infant and Toddler Foods in the United States, 2015. Nutrients 2020; 12:nu12082439. [PMID: 32823695 PMCID: PMC7469030 DOI: 10.3390/nu12082439] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 08/06/2020] [Accepted: 08/11/2020] [Indexed: 11/30/2022] Open
Abstract
Objectives: To describe the iron content of commercially available infant and toddler foods. Methods: Nutrition Facts label data were used from a 2015 database of 1037 commercial infant and toddler food and drink products. Products were grouped into food categories on the basis of name, ingredients, target age, and reference amounts customarily consumed (RACC). Mean and median iron content per 100 g and per RACC were calculated. The proportion of products considered good and excellent sources of iron were determined on the basis of percent daily value (% DV) thresholds. Results: Among products marketed for infants (aged 4–12 months), infant cereals had the highest mean (6.19 mg iron per RACC; 41.25 iron mg per 100 g) iron content. Among products marketed for toddlers (aged 12–36 months), vegetable-based mixtures or meals contained the highest mean iron in mg per RACC (mean: 2.97 mg) and dry, grain-based desserts had the highest mean iron in mg per 100 g (mean: 6.45 mg). Juice and drink products had the lowest mean iron contents in both infant and toddler products. Conclusions: Most commercially available infant cereals are considered to be an excellent source of iron, likely from fortification, but wide variability was observed in iron content by food category. Products that are considered good or excellent sources of iron (≥10% DV) can help consumers identify products with higher iron content, such as infant cereals or toddler vegetable-based mixtures/meals.

Abstract
BACKGROUND The human gut microbiome is recognized as an important determinant of human health, yet little is known about how dietary habits are related to the microbiome in post-weaned, pre-pubescent children. OBJECTIVE The goal of this work was to link quantitative dietary intake with microbiome features in a diverse population of children consuming a predominantly Western diet. DESIGN This was a cross-sectional study. PARTICIPANTS/SETTINGS English- or Spanish-speaking families with healthy children between the ages of 2 and 9 years were recruited from a community-based, early childhood learning center in suburban Los Angeles, California between June and September 2014. MAIN OUTCOME MEASURES Children included in the analyses (n=75) contributed three fecal samples and three quantitative 24-hour dietary recalls using the multiple-pass method with an average of 5.7 days between samples. Microbial communities of each fecal sample were characterized using Illumina sequencing of the 16S ribosomal RNA gene. Dietary recalls were analyzed using the Automated Self-Administered 24-Hour Recall Dietary Assessment Tool. STATISTICAL ANALYSIS PERFORMED Associations between dietary factors and microbiome features were assessed using the Kruskal-Wallis test, Spearman rank correlations, or permutational multivariate analysis of variance. For demographic and health-related variables, χ2 analyses were used to test for differences between age groups for categorical variables. RESULTS Our results show that age is correlated with three metrics of microbiome diversity (P<0.05) and is associated with both community structure (P=0.0488) and membership (P=0.0002). Several dietary food groups and nutrients were likewise associated with microbiome features. For example, consumption of non-whole-grain foods was associated with community structure (P=0.0089) and membership (P=0.0057), but not diversity (P>0.05). Likewise, the relative abundance of several bacterial taxa were linked to consumption of particular food groups and/or nutrients, as illustrated by the positive associations between total fruit (Pfalsediscovery rate<0.05) and fiber (Pfalsediscovery rate<0.05) consumption with the relative abundance of the Lachnospira genera. CONCLUSIONS This hypothesis-generating study demonstrates that the composition of the child gut microbiome remains dynamic beyond the age of 3 years and responds to dietary differences across individuals. In particular, non-whole-grain foods fortified with vitamins and minerals appear to be associated with the composition of the microbiome. Future interventional or model organism-based studies will be needed to test these associations between diet and microbiome composition.

Abstract
The first 2 y of life are characterized by several transitions that can affect growth, development, and eating patterns long term. These include a shift from a primarily milk-based eating pattern to introduction of complementary foods at ∼4-6 mo of age, and passage to family-meal patterns in toddler years. Recognizing the importance of this critical period, the Dietary Guidelines for Americans from 2020 onwards will include guidance for children aged birth to 24 mo (B-24). Few large-scale surveys provide comprehensive, nationally representative, quantitative, recent data on infant and toddler nutrition in the United States. The continuous NHANES has collected data relevant to this initiative since 1999 using standardized interview and examination protocols. These include data on infant feeding practices, dietary intakes (foods, beverages, and supplements), anthropometry, and blood-based nutritional status on nationally representative samples of infants and toddlers. NHANES data can be used to describe large group-level consumption patterns, as well as trends over time for B-24 children overall, and by demographic groups (e.g., race-ethnic and income groups). In addition, NHANES data can be analyzed to examine adherence to nutrition-related recommendations, such as those from the American Academy of Pediatrics (AAP), and to track Healthy People 2020 objectives. This paper provides an update on NHANES nutrition monitoring in B-24 children since our previous publication (which provided details through NHANES 2009-2010) and describes data collection since 2010 and plans for upcoming cycles. It also describes key NHANES-based findings published in the last 5 y on infant feeding practices, dietary intakes and supplement use, and nutritional status of US children aged <2 y. Findings related to existing recommendations, such as from the AAP, are presented when available. This information can inform researchers and policymakers on the state of nutrition in the US B-24 population and its subgroups of interest.

Abstract
BACKGROUND Mothers who feed their children with infant food have increased have over the years leaving a large percentage of children who consume other types of liquid food for supplementation or as alternatives. AIM Determining the levels of essential trace metals in these formulae with the aim of ascertain their appropriateness is considered important. METHODS Iron, zinc, manganese, chromium and cobalt in 26 infant formulae purchased from Port Harcourt city, Nigeria were determined by Atomic Absorption Spectrophotometry. The estimated daily intake EDI and percentage of EDI to the recommended daily allowance of these essential trace metals were used in the exposure assessment. RESULTS The highest mean concentration of Mn, Cr and Co was found in the milk based (0.15 ± 0.09 mg/kg), (0.61 ± 0.70 mg/kg), (0.12 ± 0.32 mg/kg) compared to the cereal based and cereal mix based but the differences was also not significant. The EDI of chromium in the infant formulae exceeded the RDA. CONCLUSION Infant formulae may add to the chromium body burden of infants in Nigeria.

Abstract
Optimized nutrition during the first 1000 days (from conception through the 2nd birthday) is critical for healthy development and a healthy life for the newborn. Pregnancy and the postpartum period are accompanied by physiological changes, increased energy needs, and changing requirements in the nutrients critical for optimal growth and development. Infants and toddlers also experience physiological changes and have specific nutritional needs. Food and nutrition experts can provide women of childbearing age with adequate dietary advice to optimize nutrition, as well as guidance on selecting appropriate dietary supplements. Considering the approaching 2020-2025 Dietary Guidelines for Americans (DGA) will be making specific recommendations for children, it is important to provide accurate scientific information to support health influencers in the field of nutrition. The purpose of this review is to summarize the nutrition and supplementation literature for the first 1000 days; to highlight nutritional and knowledge gaps; and to educate nutrition influencers to provide thoughtful guidance to mothers and families. Optimal nutrition during pregnancy through early childhood is critical for supporting a healthy life. Nutrition influencers, such as dietitians, obstetricians/gynecologists, and other relevant health professionals, should continue guiding supplement and food intake and work closely with expectant families and nutrition gatekeepers.

J Nutr 2019; 149:1230-1237. [PMID: 31049587 PMCID: PMC6602894 DOI: 10.1093/jn/nxz054] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 01/10/2019] [Accepted: 03/04/2019] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Many updates to young child feeding recommendations have been published over the past decade, but concurrent intake trends have not been assessed. OBJECTIVE The aim of this study was to evaluate adequacy and trends in energy and nutrient intakes of US infants and children aged 0-47.9 mo through use of Feeding Infants and Toddlers Study (FITS) data from 2002, 2008, and 2016. METHODS FITS are cross-sectional surveys of parents/caregivers of infants and young children (FITS 2002, n = 2962; FITS 2008, n = 3276; FITS 2016, n = 3235). Dietary intakes were assessed by telephone with trained interviewers using the Nutrition Data System for Research. Mean ± SE nutrient intakes were calculated. Diet adequacy was assessed with the nutrient adequacy ratio (NAR) for 17 nutrients and the corresponding mean adequacy ratio. RESULTS Energy and macronutrient intakes were generally stable across surveys, but significant decreases for saturated fat and total sugars and an increase in fiber were observed among 6-11.9-mo-olds and 12-23.9-mo-olds (P-trend < 0.0001). Mean sodium intakes exceeded Adequate Intakes (AI) for all ages, whereas fiber intakes were universally below the AI. Nutrients with the lowest NAR values were vitamin D (range 0.41-0.67/1.00) and vitamin E (range 0.60-0.79/1.00 for 2008 and 2016). For iron, infants aged 6-11.9 mo had the lowest NAR values at 0.77-0.88/1.00, compared to 0.85-0.89/1.00 for 12-47.9-mo-olds. Potassium was low from 12 to 47.9 mo (NAR range 0.55-0.63/1.00 across survey years). The nutrients with the greatest decline in mean intakes were iron and vitamins D and E among 6-11.9-mo-olds, and vitamin D and potassium among 12-23.9-mo-olds in 2016 compared to 2002. CONCLUSIONS The diets of US infants and young children were generally adequate for most micronutrients and stable over time, but sodium intakes were too high, and nutrient gaps still existed, especially for vitamins D, E, and fiber across ages and for iron among infants.

OBJECTIVE The aim of this study was to examine the utility of serum iodine for assessing iodine intake in children. METHODS One blood sample and 2 repeated 24-h urine samples (1-mo interval) were collected from school-age children in Shandong, China. Serum free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH), thyroglobulin (Tg), total iodine (StI), and non-protein-bound iodine (SnbI) concentrations and urine iodine (UIC) and creatinine (UCr) concentrations were measured. Iodine intake was estimated based on two 24-h urine iodine excretions (24-h UIE). Associations between serum iodine and other factors were analyzed using the Spearman rank correlation test. Receiver operating characteristic (ROC) curves were used to illustrate diagnostic ability of StI and SnbI. RESULTS In total, 1686 children aged 7-14 y were enrolled. The median 24-h UIC for the 2 collections was 385 and 399 μg/L, respectively. The median iodine intake was estimated to be 299 μg/d and was significantly higher in boys than in girls (316 μg/d compared with 283 μg/d; P < 0.001). StI and SnbI were both positively correlated with FT4 (ρ = 0.30, P < 0.001; and ρ = 0.21, P < 0.001), Tg (ρ = 0.21, P < 0.001; and ρ = 0.19, P < 0.001), 24-h UIC (ρ = 0.56, P < 0.001; and ρ = 0.47, P < 0.001), 24-h UIE (ρ = 0.46, P < 0.001; and ρ = 0.49, P < 0.001), urine iodine-to-creatinine ratio (ρ = 0.58, P < 0.001; and ρ = 0.62, P < 0.001), and iodine intake (ρ = 0.49, P < 0.001; and ρ = 0.53, P < 0.001). The areas under the ROC curves for StI and SnbI for the diagnosis of excessive iodine intake in children were 0.76 and 0.77, respectively. The optimal StI and SnbI threshold values for defining iodine excess in children were 101 and 56.2 μg/L, respectively. CONCLUSIONS Serum iodine was positively correlated with iodine intake and the serum FT4 concentration in children. It is a potential biomarker for diagnosing excessive iodine intake in children. This trial was registered at clinicaltrials.gov as NCT02915536.

Abstract
The One Health concept focuses on the interrelationship between the health of humans, animals, and the environment. There is a delicate balance among these relationships, and when an imbalance exists, the effects can be catastrophic. Such an imbalance occurred in 2010, when elevated lead exposure in rural communities in northwestern Nigeria resulted in the deaths of an estimated 400 children younger than 5 years in a 12-month period. Before the children became ill, waterfowl began to die in great numbers, a connection that would not be realized until much later. This review covers toxicodynamics and the neurotoxic effects of lead in the developing central nervous system, the role that animals can play in recognizing lead exposure and contamination, and environmental sources of lead exposure. The experiences in Nigeria may be especially pertinent to the emerging problems associated with lead exposure and poisoning in the United States.

[PMID: 28696361 PMCID: PMC5537847 DOI: 10.3390/nu9070733] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2017] [Revised: 06/30/2017] [Accepted: 07/07/2017] [Indexed: 11/27/2022] Open
Abstract
Iron deficiency (ID) affects 13.5% of 1-2 years old children in the US and may have a negative impact on neurodevelopment and behavior. Iron-fortified infant cereal is the primary non-heme iron source among infants aged 6-11.9 months. The objective of this study was to compare iron intakes of infant cereal users with non-users. Data from the Feeding Infants and Toddlers Study 2008 were used for this analysis. Based on a 24-h recall, children between the ages of 4-17.9 months were classified as 'cereal users' if they consumed any amount or type of infant cereal and 'non-users' if they did not. Infant cereal was the top source of dietary iron among infants aged 6-11.9 months. The majority of infants (74.6%) aged 6-8.9 months consumed infant cereal, but this declined to 51.5% between 9-11.9 months and 14.8% among 12-17.9 months old toddlers. Infant cereal users consumed significantly more iron than non-users across all age groups. Infants and toddlers who consume infant cereal have higher iron intakes compared to non-users. Given the high prevalence of ID, the appropriate use of infant cereals in a balanced diet should be encouraged to reduce the incidence of ID and ID anemia.
