Yisak H, Gedamu D, Ewunetei A. Untimely Initiation of Whole Cow Milk, Stunting, and Related Factors in South Gondar, Ethiopia. Pediatric Health Med Ther 2024; 15:159-170. [PMID: 38585425 PMCID: PMC10999182 DOI: 10.2147/phmt.s454615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 03/22/2024] [Indexed: 04/09/2024] Open
Abstract
Introduction Despite being an excellent source of essential nutrients, whole cow's milk poses risks for young children. This is mainly due to its association with adverse effects, including growth inhibition, delayed brain and motor development, and increased morbidity and mortality. The current study aimed to evaluate the occurrence of untimely introduction of whole cow milk, stunting and related factors among children below the age of 5 years. Methods A community-centered survey was implemented on 806 mother-child matches. Expressive statistics such as frequency, magnitude, mean and standard deviation were computed. Multivariable logistic regression was done to discover independent determinants of the dependent variables. A p-value of <0.05 was used to affirm significant association. Results From the survey participant children 311 (39.2%) of them were stunted. About 453 (57.1%) of children were fed whole cow milk earlier than the age of one year. Mothers who are able to read and write were 49% less likely to initiate cow milk earlier than the age of one year with AOR = 0.51, 95% CI 0.33-0.78. Not attending the growth monitoring and promotion service is a risk for untimely introduction of whole cow milk (AOR = 3.47, 95% CI 2.43-4.94). Children who did not start consuming whole cow milk earlier than the age of one year were 54% less likely to be stunted than those who started consuming whole cow milk before the age of one year (AOR = 0.46, 95% CI 0.33-0.65). Conclusion More than half of the study participant children started consuming whole cow milk before the age of one year. Children who did not start consuming whole cow milk early were less likely to be stunted.

Abstract
INTRODUCTION Defining accurate age- and sex-specific reference intervals (RIs) for hematology parameters, especially for the pediatric population, is important for making an appropriate clinical diagnosis. To address gaps, we established age-specific RIs for 11 hematologic parameters in Iranian children younger than 30 months for the first time. METHODS Fresh whole blood samples collected from a total of 344 participants (males: 158 and females: 186) ages 3 days to 30 months, with a mean age of 12.91 ± 7.15 months, were recruited from healthcare centers in Mashhad, Iran. Hematologic parameters, including complete blood count (CBC), were analyzed on the Sysmex auto-analyzer system (KX-21 N). RIs were calculated with 90% confidence intervals using the direct method based on CLSI Ep28-A3 and C28-A3 guidelines. RESULTS None of the CBC parameters required sex partitioning. Of 11 CBC parameters, six required age partitions of 3 days-<4 months, 4-<10, 10-<15, and 4-<30 months. Five parameters (i.e., white blood cell count, mean corpuscular hemoglobin concentration, mean platelet volume, red cell distribution width, and platelet distribution width) did not demonstrate age-specific changes. RIs of red blood cell count and hematocrit, as well as hemoglobin, increased with age, while mean corpuscular volume, mean corpuscular hemoglobin, and platelet count, decreased with age. CONCLUSION In this study, we established RIs for 11 hematology parameters in young children. Age partitioning was required for six parameters demonstrating marked changes during the early period of growth and development and necessitating the use of pediatric-specific reference standards.

Abstract
CONTEXT The timing of introducing complementary feeding (CF) is crucial because premature or delayed CF can be associated with adverse health outcomes in childhood and adulthood. OBJECTIVE This systematic review aims to evaluate the impact of the timing of CF introduction on health, nutrition, and developmental outcomes among normal-term infants. DATA SOURCES Electronic databases and trial registries were searched, along with the reference lists of the included studies and relevant systematic reviews. DATA EXTRACTION Two investigators independently extracted data from the included studies on a standardized data-extraction form. DATA ANALYSIS Data were meta-analyzed separately for randomized controlled trials (RCTs) and observational studies on the basis of early introduction of CF (< 3 months, < 4 months, < 6 months of age) or late introduction of CF (> 6 months, > 8 months of age). Evidence was summarized according to GRADE criteria. In total, 268 documents were included in the review, of which 7 were RCTs (from 24 articles) and 217 were observational studies (from 244 articles). Evidence from RCTs did not suggest an impact of early introduction, while low-certainty evidence from observational studies suggested that early introduction of CF (< 6 months) might increase body mass index (BMI) z score and overweight/obesity. Early introduction at < 3 months might increase BMI and odds of lower respiratory tract infection (LRTI), and early introduction at < 4 months might increase height, LRTI, and systolic and diastolic blood pressure (BP). For late introduction of CF, there was a lack of evidence from RCTs, but low-certainty evidence from observational studies suggests that late introduction of CF (> 6 months) might decrease height, BMI, and systolic and diastolic BP and might increase odds of intestinal helminth infection, while late introduction of CF (> 8 months) might increase height-for-age z score. CONCLUSION Insufficient evidence does suggest increased adiposity with early introduction of CF. Hence, the current recommendation of introduction of CF should stand, though more robust studies, especially from low- and middle-income settings, are needed.

Anaemia and associated factors among children aged 6-23 months in agrarian community of Bale zone: a cross-sectional study. J Nutr Sci 2022; 11:e96. [PMID: 36405097 PMCID: PMC9641524 DOI: 10.1017/jns.2022.63] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 07/04/2022] [Accepted: 07/18/2022] [Indexed: 11/06/2022] Open
Abstract
Anaemia remains among the most prevalent nutritional problems among children in developing countries. In Ethiopia, more than half of children <5 years of age are anaemic. In the early stages of life, it leads to poor cognitive performance, delay psychomotor development and decreases working capacity in later life. The present study aimed to assess the prevalence and associated factors of anaemia among children aged 6-23 months in the Bale zone. A community-based cross-sectional study was conducted from 1 to 30 June 2021. Multistage stratified sampling and simple random sampling techniques were employed to select 770 samples. An interviewer-administered questionnaire was used to collect data on socio-demographic, child health and feeding practices. Haemoglobin levels were estimated using a portable Hemosmart machine. Children with haemoglobin values below 11 g/dl were considered anaemic. Binary logistic regression analysis was performed to identify factors associated with anaemia. Statistical significance was set at P < 0⋅05. The prevalence of anaemia was 47⋅9 % (95 % CI (44⋅4, 51⋅5)). The multivariate analysis showed that child age (6-11 months) (AOR 1⋅47; 95 % CI (1⋅06, 2⋅03)), household food insecurity (AOR 1⋅44; 95 % CI (1⋅01, 2⋅04)), having diarrhoea and cough in the past 2 weeks (AOR 1⋅70; 95 % CI (1⋅18, 2⋅44)) and (AOR 1⋅97; 95 % CI (1⋅28, 3⋅04), respectively), not consuming the recommended dietary diversity (AOR 2⋅72; 95 % CI (1⋅96, 3⋅77)) and stunting (AOR 1⋅88; 95 % CI (1⋅31, 2⋅70)) were significantly associated with anaemia. Anaemia in children aged 6-23 months was a severe public health problem in the study area. Integrated nutritional interventions combined with iron fortification and supplementation is recommended.

Abstract
Introduction and Aim: Anaemia is a global problem with 42% prevalence. Analysis of risk factors of anaemia will be useful in formulating health programs. This case control study was done to analyse the risk factors for anaemia in infants and young children.
Materials and Methods: This study was done in hospitalised children in a University hospital. Children with anaemia in age group between 6 and 24 months. Age and sex matched children without anaemia were controls. Demographic details, maternal details and feeding practices were compared.
Results: 147 children were recruited in both groups. There was no significant difference in demographic factors. Exclusive breast feeding (EBF) more than four months (95.2% vs 70.1%, p value<0.001), vegetarian diet (53.7% vs 40.1%, p value=0.019), complimentary diet containing either cereals or pulses alone (83% vs 47.6%, p value< 0.001), cow’s milk intake more than 400 ml (36.1% vs 18.4%, p value=0.001) and birth order more than one (62.6% vs 32%, p value<0.001) were identified as risk factors.
Conclusion: Iron supplements are essential in infants, if EBF is practised beyond 4 months and additional vitamin b12 supplements if vegetarian diet is followed. Cow’s milk intake should be less than 400 ml, to protect against anaemia.

Prevalence and determinants of severity levels of anemia among children aged 6-59 months in sub-Saharan Africa: A multilevel ordinal logistic regression analysis. PLoS One 2021; 16:e0249978. [PMID: 33891603 PMCID: PMC8064743 DOI: 10.1371/journal.pone.0249978] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 03/18/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Anemia is a major public health problem affecting more than half of children under the age of five globally. It has serious short- and long-term consequences including growth retardation, impaired motor and cognitive development, and increased morbidity and mortality. Despite anemia is the leading cause of child mortality in sub-Saharan Africa, there is limited evidence on the prevalence and determinants of anemia among under-five children in sub-Saharan Africa. Therefore, this study aimed to investigate the prevalence and determinants of severity levels of anemia among children aged 6-59 months in sub-Saharan Africa. METHODS This study was based on the most recent Demographic and Health Survey (DHS) data of 32 sub-Saharan African countries. A total weighted sample of 135,619 children aged 6-59 months was included in the study. Considering the hierarchical nature of DHS data and the ordinal nature of anemia, a multilevel ordinal logistic regression model was applied. Proportional odds assumption was tested by Brant test and it was satisfied (p-value = 0.091). Besides, deviance was used for model comparison. Variables with a p-value ≤0.2 in the bivariable analysis were considered for the multivariable analysis. In the multivariable multilevel proportional odds model, the Adjusted Odds Ratio (AOR) with 95% Confidence Interval (CI) were reported for potential determinant factors of severity levels of anemia. RESULTS The overall prevalence of anemia among children aged 6-59 months in sub-Saharan Africa was 64.1% [95% CI: 63.9%, 64.4%]. Of which, 26.2% were mildly anemic, 34.9% moderately anemic and 3% severely anemic. Poor maternal education, lower household wealth status, large family size, being male child, multiple births, having fever in the last two weeks, having diarrhea in the last two weeks, higher-order birth, maternal anemia, underweight, wasted, and stunted were significantly associated with increased odds of higher levels of anemia. Whereas, being 24-59 months age, taking drugs for an intestinal parasite, and born from mothers aged ≥ 20 years were significantly associated with lower odds of higher levels of anemia. CONCLUSION Severity levels of anemia among children aged 6-59 months in sub-Saharan Africa was a major public health problem. Enhancing maternal education, providing drugs for an intestinal parasite, designing interventions that address maternal anemia, febrile illness, and diarrheal disease, and strengthening the economic status of the family are recommended to reduce childhood anemia. Furthermore, it is better to strengthen the strategies of early detection and management of stunted, wasted, and underweight children to decrease childhood anemia.

Abstract
BACKGROUND This study aimed to assess the association between iron deficiency anaemia (IDA) and dental caries in early childhood. METHODS A total of 40 children with proven IDA and another 40 healthy age and sex-matched children were enrolled in this cross-sectional study. Legal guardians were interviewed to collect data on oral hygiene measures and dietary habits. Anthropometric measurements were performed for all participants, and blood samples were collected to assess complete blood count and body iron status. Patients were confirmed to have IDA based on haemoglobin level (Hb), red blood cells indices and body iron status. Caries experience was determined based on the number of decayed, missing and filled primary teeth using dmft index. RESULTS A statistically significant negative correlation between dmft index scores and haemoglobin level (r = -0.454, P < 0.001) and mean corpuscular haemoglobin (MCH) level (r = -0.380, P = 0.001) was detected, and in accordance there was a positive statistically significant correlation between caries experience and the presence of anaemia (r = -0.60, P < 0.001). CONCLUSION In early childhood, dental caries might coexist with IDA even in its mildest form. All children exhibiting severe early childhood caries should be investigated for IDA and anaemia should be managed if present.

Abstract
BACKGROUND Cow milk is an important source of macro-and micronutrients. However, it has low iron content but high content of casein and calcium thus could negatively influence hemoglobin synthesis. On the other hand, camel milk contains higher iron concentration than cow milk. In addition, the majority of iron in camel milk is associated with the lower molecular fraction of casein suggesting better bioavailability. Furthermore, vitamin C concentration, a useful iron absorption enhancer, is more than three-fold greater in camel milk than cow milk. This study compared hemoglobin concentration among young children consuming consistently cow milk or camel milk. METHODS Hemoglobin concentration of young children (aged 6-59 mo) from settled pastoralist communities of the Somali region, Ethiopia, consistently consuming cow milk (n = 166) or camel milk (n = 166) was determined. In addition, socio-demographic and water, sanitation, and hygienic (WASH) conditions of study participants' households were captured. Furthermore, dietary intake and anthropometric characteristics of participating children were assessed. RESULTS Among the participating children, 38.6% were underweight, 33.4% were stunted, and 34.5% were wasted. In addition, 77.4% of children were anemic. The present study households had poor WASH conditions. Only 0.6% of children had the minimum acceptable dietary diversity. There was small but significant mean hemoglobin difference among camel milk and cow milk consuming children (9.6±1.8 g/dl vs 9.1±2.2 g/dl; p = 0.012). In addition, the odds of low hemoglobin concentration was greater among cow milk consuming children than camel milk consuming children [AOR 2.17; 95 CI; 1.39, 3.37; p = 0.001]. However, the overall anemia prevalence among the two groups was similar. CONCLUSION Camel milk consumption is associated with better hemoglobin concentration but may not be sufficient to prevent anemia in populations from resource poor settings. The etiology of anemia is multifactorial thus further studies on the link between milk consumption and hemoglobin concentration are important.

Prevalence of Anemia and Associated Factors among Infants and Young Children Aged 6-23 Months in Debre Berhan Town, North Shewa, Ethiopia. J Nutr Metab 2020; 2020:2956129. [PMID: 33414958 PMCID: PMC7768586 DOI: 10.1155/2020/2956129] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Revised: 08/23/2020] [Accepted: 12/07/2020] [Indexed: 02/03/2023] Open
Abstract
Background Anemia is a problem of both the developed and developing world, which occurs in all age groups of the population. Half of the anemia cases are due to iron deficiency and affects physical growth and mental development. Nevertheless, there is a scarcity of information about anemia and associated factors among infants and young children aged 6 to 23 months in low-income countries like Ethiopia. Objective The aim of this study was to assess the prevalence of anemia and associated factors among infants and young children aged 6–23 months. Methods A community-based cross-sectional study design was used among 531 mothers/caregivers-children pairs in Debre Berhan Town, North Shewa, Ethiopia, from February 1 to March 2, 2018. The cluster sampling technique was used to select the study participants. Sociodemographic data were collected from mothers/caregivers using pretested structured questionnaires. Hemoglobin levels were measured using a HemoCue analyzer machine (HemoCue® Hb 301, Ängelholm, Sweden). All relevant data were described using descriptive statistics such as frequencies, proportions, mean, and standard deviation. Odds ratio and 95% CI were estimated using binary logistic regression to measure the strength of the association between anemia and explanatory variables. The level of statistical significance was declared at P < 0.05. Results The overall prevalence of anemia was 47.5% (95% CI: 43.1–51.4%) of which 18.3% were mildly anemic, 25% were moderately anemic, and 4.1% were severely anemic. In multivariable logistic regression analysis, household food insecurity (AOR = 2.7, 95% CI: 1.6–4.5), unmet minimum dietary diversity (AOR = 2.5, 95% CI: 1.4–4.3), stunting (AOR = 2.3, 95% CI: 1.2–4.3), and underweight (AOR = 2.7, 95% CI: 1.4–5.4) positively associated with anemia while having ≥4 antenatal care visits (AOR = 0.5, 95% CI: 0.3–0.9) and met minimum meal frequency (AOR = 0.25, 95% CI: 0.14–0.45) had a protective effect against anemia. Conclusion Generally, the study showed that anemia was a severe public health problem among infants and young children in the study setting. Antenatal care visit, meal frequency, dietary diversity, underweight, stunting, and food insecurity significantly associated with anemia. Therefore, efforts should be made to strengthen infant and young child feeding practices and antenatal care utilization and ensure household food security, thereby improving the nutritional status of children.

BACKGROUND The perinatal period is associated with a high risk of infant anemia. The aim of the present study was to determine the prevalence of infant and maternal anemia during the late lactation period and the risk factors for anemia in Japan. METHODS This retrospective cohort study was based on data from health checkups of healthy infants at 6-7 and 9-10 months of age and their mothers who visited Akitsu Children's Clinic between September 2013 and August 2015. Complete blood count data from infant blood samples obtained at 6-7 months and 9-10 months and from maternal blood samples obtained at 6-7 months, information on feeding methods, and other related parameters were analyzed. RESULTS Data from 388 mother-infant pairs were analyzed. The prevalence of infant anemia was 21.1% at 6-7 months and 29.1% at 9-10 months. The prevalence of anemia in exclusively breast-fed infants was 28.4% at 6-7 months and 40.0% at 9-10 months. The risk factors for infant anemia at 9-10 months were exclusive breast-feeding, lower gestational age at birth, male sex, and high weight gain. The prevalence of maternal anemia was 10.5%. There was no correlation between infant and maternal hemoglobin in exclusively breast-fed infants. CONCLUSIONS Japanese infants who were breast-fed exclusively had a high prevalence of anemia. A nationwide strategy to prevent anemia is required to prevent infant anemia, even in a nutrition-rich country such as Japan.

Abstract
OBJECTIVES To estimate the magnitude of anaemia, iron deficiency (ID), iron deficiency anaemia (IDA) and to explore epidemiological features of ID and feeding practices among infants aged 12 months in Qatar. SETTING Well baby clinics in 14 randomly selected primary healthcare centres covering all geographical areas on the national level. PARTICIPANTS Three hundred and six (163 male and 143 female) infants of all nationalities were enrolled. Mothers were asked to complete a predesigned interview questionnaire and infants were blood tested for anaemia, ID and IDA. OUTCOME MEASURES Cut-off point used to diagnose anaemia was haemoglobin <11.1 g/dL, and to diagnose ID, serum ferritin <6 ug/L with normal C reactive protein. RESULTS Prevalence of anaemia was 23.5%, ID was 9.2% and IDA was 7.8%. ID was more prevalent among non-Qatari infants compared with Qatari (10.9% vs1.7%, p=0.029), more prevalent among infants born to housewives and to families of low income (p≤0.05). With regard to feeding practice, ID was higher in infants who continued breastfeeding until the age of 1 year and among those who never took infant formula milk (p≤0.05). Mothers who received infant feeding counselling had less ID occurrence among their infants compared with their counterparts who did not receive such counselling (4.2%vs13.4%, p=0.005). CONCLUSION Although ID and IDA among infants in Qatar are less prevalent compared with many developing countries, still further efforts are needed for improvement towards more developed countries. Efforts should be contextualised and should target the key epidemiological features with special emphasis on infant feeding and infant feeding counselling to mothers.

The Prevalence of Micronutrient Deficiencies and Inadequacies in the Middle East and Approaches to Interventions. Nutrients 2017; 9:nu9030229. [PMID: 28273802 PMCID: PMC5372892 DOI: 10.3390/nu9030229] [Citation(s) in RCA: 84] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2016] [Accepted: 02/28/2017] [Indexed: 12/28/2022] Open
Abstract
Micronutrient deficiencies and inadequacies constitute a global health issue, particularly among countries in the Middle East. The objective of this review is to identify micronutrient deficits in the Middle East and to consider current and new approaches to address this problem. Based on the availability of more recent data, this review is primarily focused on countries that are in advanced nutrition transition. Prominent deficits in folate, iron, and vitamin D are noted among children/adolescents, women of childbearing age, pregnant women, and the elderly. Reports indicate that food fortification in the region is sporadic and ineffective, and the use of dietary supplements is low. Nutrition monitoring in the region is limited, and gaps in relevant information present challenges for implementing new policies and approaches to address the problem. Government-sponsored initiatives are necessary to assess current dietary intakes/patterns, support nutrition education, and to reduce food insecurity, especially among vulnerable population groups. Public-private partnerships should be considered in targeting micronutrient fortification programs and supplementation recommendations as approaches to help alleviate the burden of micronutrient deficiencies and inadequacies in the Middle East.

Breastfeeding, Mixed, or Formula Feeding at 9 Months of Age and the Prevalence of Iron Deficiency and Iron Deficiency Anemia in Two Cohorts of Infants in China. J Pediatr 2017; 181:56-61. [PMID: 27836288 PMCID: PMC5274569 DOI: 10.1016/j.jpeds.2016.10.041] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2016] [Revised: 08/25/2016] [Accepted: 10/12/2016] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To assess associations between breastfeeding and iron status at 9 months of age in 2 samples of Chinese infants. STUDY DESIGN Associations between feeding at 9 months of age (breastfed as sole milk source, mixed fed, or formula fed) and iron deficiency anemia (IDA), iron deficiency, and iron sufficiency were determined in infants from Zhejiang (n = 142) and Hebei (n= 813) provinces. Iron deficiency was defined as body iron < 0 mg/kg, and IDA as iron deficiency + hemoglobin < 110 g/L. Multiple logistic regression assessed associations between feeding pattern and iron status. RESULTS Breastfeeding was associated with iron status (P < .001). In Zhejiang, 27.5% of breastfed infants had IDA compared with 0% of formula-fed infants. The odds of iron deficiency/IDA were increased in breastfed and mixed-fed infants compared with formula-fed infants: breastfed vs formula-fed OR, 28.8 (95% CI, 3.7-226.4) and mixed-fed vs formula-fed OR, 11.0 (95% CI, 1.2-103.2). In Hebei, 44.0% of breastfed infants had IDA compared with 2.8% of formula-fed infants. With covariable adjustment, odds of IDA were increased in breastfed and mixed-fed groups: breastfed vs formula-fed OR, 78.8 (95% CI, 27.2-228.1) and mixed-fed vs formula-fed OR, 21.0 (95% CI, 7.3-60.9). CONCLUSIONS In both cohorts, the odds of iron deficiency/IDA at 9 months of age were increased in breastfed and mixed-fed infants, and iron deficiency/IDA was common. Although the benefits of breastfeeding are indisputable, these findings add to the evidence that breastfeeding in later infancy identifies infants at risk for iron deficiency/IDA in many settings. Protocols for detecting and preventing iron deficiency/IDA in breastfed infants are needed. TRIAL REGISTRATION ClinicalTrials.gov: NCT00642863 and NCT00613717.

Abstract
OBJECTIVES The primary objective of this study was to determine the prevalence of iron deficiency anaemia (IDA) in hospitalised 6- to 24-month-old infants in rural versus urban settings. The secondary objective was to determine associated risk factors in rural versus urban settings. METHODS A 6-month prospective multicentre cross-sectional study was conducted in paediatrics departments of three Lebanese hospitals. Preterm to term infants aged 6-24 months were included. Infants with blood disorders, chronic infections, congenital immunodeficiency and mental or congenital growth retardation were excluded. Incidence of IDA was assessed using haematologic laboratory values, while risk factors were assessed using questionnaires addressed to infants' caregivers. For data analysis, P values, chi-squared and logistic regression were used. KEY FINDINGS Among 520 screened infants, a total of 100 patients were selected. Thirty-seven per cent of patients were anaemic with haemoglobin levels <11 g/dl. Significant risk factors included: exclusive breastfeeding for more than 6 months (95% CI, 1.03 to 8.9; P = 0.043), low family income (95% CI, 0.19 to 0.98; P = 0.045), residing in rural areas (95% CI, 0.064 to 0.0509; P < 0.001), inadequate maternal iron supply (95% CI, 1.01 to 8.26; P = 0.05), low maternal education level (95% CI, 0.07 to 0.88; P = 0.03) and lack of infant iron supply (95% CI, 1.39 to 8.41; P = 0.007). CONCLUSION Incidence of IDA among Lebanese infants is moderate and multifactorial. High maternal education level, urban residence, giving iron supplements to exclusively breastfed infants starting from 6 months of age, adequate family income and iron supplementation in both mother and infant are significant protective factors against anaemia in this population.

Renal functional and structural integrity in infants with iron deficiency anemia: relation to oxidative stress and response to iron therapy. Pediatr Nephrol 2015; 30:1835-42. [PMID: 25980471 DOI: 10.1007/s00467-015-3122-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2015] [Revised: 04/23/2015] [Accepted: 04/27/2015] [Indexed: 01/12/2023]
Abstract
BACKGROUND Iron deficiency anemia (IDA) is the most common nutritional deficiency in the world. The aim of our study was to evaluate and compare renal functional and structural integrity in 50 infants with IDA and 50 healthy controls and to assess the relation between IDA and oxidative stress and response to iron therapy. METHODS This was a prospective study in which peripheral blood samples were collected from all study subjects and the following laboratory investigations performed: serum iron profile, urinary microalbumin, urinary leucine aminopeptidase (LAP), fractional excretion of sodium (FeNa), serum total antioxidant capacity (TAC), serum malondialdehyde (MDA), serum and urinary trace elements (iron, copper, zinc, calcium and magnesium). All patients received oral iron therapy and were followed-up for 3 months. RESULTS The levels of baseline urinary markers were higher among the patients with IDA than among the controls (p < 0.05). Patients had a lower pre-therapy TAC and lower serum zinc and magnesium levels than controls as well as higher MDA and serum copper levels (p < 0.05). MDA level was positively correlated to microalbumin and LAP level (p < 0.05). Urinary LAP concentration was positively correlated to urinary trace element concentrations (p < 0.05). A significant decrease in microalbumin, LAP, FeNa, and urinary trace elements was observed post-iron therapy while hemoglobin and ferritin levels were increased (p < 0.05). CONCLUSION Among the study subjects, IDA had an adverse influence on renal functional and structural integrity which could be reversed with iron therapy. Oxidative stress played an important role in the pathogenesis of renal injury in IDA.

Abstract
Objective: Iron and folic acid are essential nutrients needed for hematopoiesis. Infants’ diet is commonly deficient in these micronutrients that lead to nutritional anemia. Aim of this study was to determine serum iron, serum ferritin and red cell folate levels among healthy breast fed, fortified milk and cow’s milk fed infants. Methods: A total of 120 infants of 4-9 months of age were enrolled in this study. It included 40 normal breast fed controls, 40 fortified milk fed (FM) and 40 cow’s milk fed (CM) infants. Serum iron, serum ferritin and red cell folate concentrations were determined using colorimetric and enzyme immunoassay techniques. Results: Mean serum iron, serum ferritin and red cell folate concentrations of breast fed control group were 120.9±68.4µg/dl, 109±71.7ng/ml and 1044.1±409.2ng/ml respectively. Fortified milk (FM) group showed significantly decreased serum iron (p<0.003) as compared with controls whereas serum ferritin and red cell folate values showed insignificant change (p=0.25 and p=0.85 respectively). However serum iron, serum ferritin and red cell folate were significantly decreased in cow’s milk fed (CM) group as compared with control subjects (p<0.04, p<0.006, p<0.02 respectively). Comparison of these biochemical parameters between FM and CM groups showed statistically significant difference of serum ferritin and red cell folate among cow’s milk group (p<0.0001 and p<0.02) whereas serum iron level showed no significant difference, a p-value being 0.38. Conclusion: Healthy breast fed infants do not need any supplementation and fortification of iron and folic acid. Fortified milk appears to be an acceptable alternative in the absence of breast milk whereas cow’s milk is a poor source of iron and folic acid in infants.

Abstract
Recently, hepcidin, an antimicrobial-like peptide hormone, has evolved as the master regulator of systemic iron homeostasis. Hepcidin integrates signals from diverse physiological inputs, forming a key connection between iron trafficking and response to infection. In this study, we aimed to investigate whether Helicobacter pylori infection modulates serum hepcidin level and response to oral iron therapy in children with iron-deficiency anemia. This was a case-control study including 60 children with iron-deficiency anemia (IDA; 30 H. pylori infected and 30 H. pylori noninfected) and 30 healthy children with comparable age and gender as the control group. Iron parameters including serum iron, ferritin, transferrin, total iron binding capacity, and transferrin saturation and serum hepcidin levels were assessed initially and after 3 months of oral iron therapy for IDA. Compared to the control group, serum hepcidin was significantly lower in H. pylori-noninfected children with IDA (P < 0.01) and significantly higher in H. pylori-infected children with IDA (P < 0.01). Hepcidin increased significantly in noninfected children with IDA after 3 months of oral iron therapy (P < 0.01). On the other hand, H. pylori-infected children showed nonsignificant change in hepcidin level after oral iron therapy (P > 0.05). Although hepcidin showed significant positive correlations with serum ferritin, hemoglobin (Hb), iron, and transferrin saturation in noninfected children with IDA (P < 0.01), it showed significant negative correlations with serum ferritin, Hb, iron, and transferrin saturation in H. pylori-infected children with IDA (P < 0.05). H. pylori infection upregulates serum hepcidin levels and was associated with diminished response to oral iron therapy in children with iron-deficiency anemia.

Abstract
PURPOSE Studies on iron status in infancy and early childhood have shown contradicting results concerning prolonged breast-feeding and cow's milk intake. The aim of the present study was to investigate associations between iron status among one-year-olds and feeding, with focus on the type of milk. METHODS Randomly selected healthy infants were prospectively investigated until 1 year of age in two cohorts born 1995-1996 (n = 114) and 2005 (n = 140). Information on birth data, feeding and growth until 12 months and iron status at 12 months was collected. Data from the two cohorts were pooled and the infants categorized into three groups according to their predominant milk consumption at 9 months of age, that is, breast milk, cow's milk or follow-on formula. RESULTS The prevalence of iron deficiency was highest in the cow's milk group and lowest in the follow-on formula group. According to a linear model, adjusted for gender, birth weight and exclusive breast-feeding duration, cow's milk consumption was negatively associated with serum ferritin (SF) and formula positively, but breast milk not. Predicted SF (μg/l) = 11.652(intercept) - 5.362(boy) + 0.005 × birth weight (g) + 2.826(exclusively breastfed ≥ 4 months) + 0.027 × formula (ml) - 0.022 × cow's milk (ml) + 0.005 × breast milk (ml). Correction for other dietary factors did not change these results. CONCLUSION In this pooled analysis, cow's milk intake in late infancy associated negatively, and follow-on formula positively, with iron status. Prolonged partial breast-feeding does not seem to be of importance for iron status. Fortified food seems to improve iron status in late infancy.
