Abstract
We examine the negative child health impacts of soil zinc (Zn) deficiency in Nepal. Soil Zn deficiency limits both crop yields and the Zn concentration in food crops, leading many to speculate that it underlies human Zn deficiency and child stunting, globally and particularly in South Asia. We find strong evidence that soil Zn deficiency does have a causal impact on child stunting in Nepal's Tarai region, the breadbasket of the country. Using causal bounds, we find that a 1 part per million increase in plant-available soil Zn - achievable with application of Zn-enriched fertilizer - decreases child stunting by between 1 and 7.5 percentage points. Multiple statistical sensitivity tests indicate that this relationship is unlikely to be manufactured by omitted, relevant variables.

Abstract
OBJECTIVE The nutritional status resultant from dietary habits along with socioeconomic conditions and the school environment are directly related to the individual's health condition not only in their childhood but also throughout adulthood. The aim of this study was to evaluate the effects of socioeconomic factors on the anthropometric profile and to analyze a probable association between this profile and biochemical markers in children attending public daycare centers. METHODS It is a transversal study developed in a probability sample of clusters of children from 6 months to 5 years old. Anthropometric and socioeconomic data were gathered at the CMEIs, questionnaires on the nutritional status were applied and blood was collected at the Family Health Units (USFs). RESULTS Female children are three times more likely to be underweight; in families with five members, it is 1/3 more likely that children of higher-educated parents are overweight. Among the results of the biochemical tests, hypervitaminosis A was a relevant aspect, positively correlating with copper (p=0.005) and zinc (p=0.008). CONCLUSION Therefore, since the influence of the family is an important predictor of overweight and its future outcomes related to nutritional deficiencies and inadequate dietary intake, educational interventions are vital as a way to pave the path to prevention.

[PMID: 35299084 DOI: 10.1016/j.clnu.2022.02.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 02/14/2022] [Accepted: 02/15/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND & AIMS Biofortification of staple crops with higher levels of micronutrients via traditional breeding methods is a sustainable strategy and can possibly complement fortification and other interventions to target micronutrient deficiencies in low resource settings, particularly among vulnerable populations such as children. We aimed to determine if iron- and zinc-biofortified pearl millet (FeZnPM, Dhanashakti, ICTP-8203Fe)-based complementary feeding improves nutritional status, including iron biomarkers and growth, in children living in urban slums of Mumbai. METHODS We conducted a randomized controlled trial of FeZnPM among 223 children aged 12-18 months who were not severely anemic at baseline (hemoglobin ≥9.0 g/dL). Children were randomized to receive either FeZnPM or conventional non-biofortified pearl millet (CPM) daily for 9 months. Iron status (hemoglobin, serum ferritin), plasma zinc, and anthropometric indicators (length, weight, mid-upper arm circumference, triceps and subscapular skinfolds) were evaluated at enrollment and throughout the trial. World Health Organization (WHO) anthropometric z-scores were calculated using WHO growth standards. Primary outcomes were hemoglobin and serum ferritin concentrations, and growth, defined as WHO z-scores. An intent to treat approach was used for analyses. We used the Hodges-Lehmann-Sen test to assess the change in primary outcomes between baseline and the last visit and report corresponding 95% confidence intervals. RESULTS At baseline, 67.7% of children were anemic (hemoglobin <11.0 g/dL) and 59.6% were iron deficient (serum ferritin <12.0 μg/L). FeZnPM did not significantly increase iron biomarkers or improve growth, compared to CPM. In subgroup analyses, FeZnPM improved hemoglobin concentrations in male children, and in children with iron deficiency or iron depletion (serum ferritin <25.0 μg/L) at baseline, relative to CPM. CONCLUSIONS Daily consumption of FeZnPM-based complementary foods did not significantly impact iron and zinc status or growth in children living in Mumbai's urban slums. However, the intervention significantly improved hemoglobin concentrations among male children and among individuals who were iron-deficient or iron-depleted at baseline. TRIAL REGISTRATION This trial is registered with Clinicaltrials.gov (ID: NCT02233764), and Clinical Trials Registry of India (ID: REF/2014/10/007731).

Vitamin D Deficiency and Its Association with Iron Deficiency in African Children. Nutrients 2022; 14:nu14071372. [PMID: 35405984 PMCID: PMC9002534 DOI: 10.3390/nu14071372] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/09/2022] [Accepted: 03/15/2022] [Indexed: 11/16/2022] Open
Abstract
Vitamin D regulates the master iron hormone hepcidin, and iron in turn alters vitamin D metabolism. Although vitamin D and iron deficiency are highly prevalent globally, little is known about their interactions in Africa. To evaluate associations between vitamin D and iron status we measured markers of iron status, inflammation, malaria parasitemia, and 25-hydroxyvitamin D (25(OH)D) concentrations in 4509 children aged 0.3 months to 8 years living in Kenya, Uganda, Burkina Faso, The Gambia, and South Africa. Prevalence of iron deficiency was 35.1%, and prevalence of vitamin D deficiency was 0.6% and 7.8% as defined by 25(OH)D concentrations of <30 nmol/L and <50 nmol/L, respectively. Children with 25(OH)D concentrations of <50 nmol/L had a 98% increased risk of iron deficiency (OR 1.98 [95% CI 1.52, 2.58]) compared to those with 25(OH)D concentrations >75 nmol/L. 25(OH)D concentrations variably influenced individual markers of iron status. Inflammation interacted with 25(OH)D concentrations to predict ferritin levels. The link between vitamin D and iron status should be considered in strategies to manage these nutrient deficiencies in African children.

Changes of Serum Ferritin, Hemoglobin, and Serum Iron (SI) and Treatment Effect of Iron Proteinsuccinylate Oral Solution Combined with Vitamin A and D Drops on Children with Nutritional Iron Deficiency Anemia. BIOMED RESEARCH INTERNATIONAL 2022; 2022:2972617. [PMID: 35071591 PMCID: PMC8776466 DOI: 10.1155/2022/2972617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Revised: 11/08/2021] [Accepted: 11/11/2021] [Indexed: 11/26/2022]
Abstract
Objective The purpose was to evaluate the treatment effect of iron proteinsuccinylate oral solution combined with vitamin A and D drops on children with nutritional iron deficiency anemia. Methods 124 children treated in the outpatient department of our hospital from January 2017 to January 2020 were selected as the study subjects. They were randomly divided into control and observation two groups. The control group was treated with iron proteinsuccinylate oral solution (1.5 mL/kg) in the morning and evening, respectively. The observation group received adjuvant treatment with oral vitamin A and D drops based on the treatment of the control group. The treatment effect of proteinsuccinylate oral solution combined with vitamin A and D drops was evaluated by the serum iron (SI), serum ferritin (SF), and transferrin (TRF) levels, the values of CD3+, CD4+, and CD4+/CD8+, and other evaluation indicators. Results After treatment, the SI and SF levels of children in both groups significantly increased (P < 0.01) while the TRF level significantly decreased (P < 0.01), and the SI and SF levels in the observation group increased more significantly, and the TRF level decreased more significantly compared with those in the control group (P < 0.01). After treatment, the values of CD3+, CD4+, and CD4+/CD8+ of children in both groups significantly increased compared with those before treatment (P < 0.01), and the values of CD3+, CD4+, and CD4+/CD8+ increased more significantly in the observation group compared with those in the control group (P < 0.01). In addition, the evaluation results of treatment effect showed that the markedly effective rate in the observation group was significantly higher than that in the control group (P < 0.01). Conclusion Iron proteinsuccinylate oral solution combined with vitamin A and D drops can better improve the anemia symptoms in children, with high application value.

J Family Med Prim Care 2022; 11:1063-1069. [PMID: 35495818 PMCID: PMC9051736 DOI: 10.4103/jfmpc.jfmpc_1137_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Revised: 10/14/2021] [Accepted: 10/23/2021] [Indexed: 11/04/2022] Open
Abstract
Context: Cobalamin and folate are essential for the synthesis of nucleic acids and in the maintenance of myelin. They are required during the period of the rapid growth of infancy and childhood. Their deficiency may result in nutritional anemia and neurological manifestations. There is paucity of literature regarding the prevalence of cobalamin and folate deficiency among North Indian children aged 6–59 months. Aim: The aim of this study was to estimate the prevalence of serum cobalamin and folate deficiency among children aged 6–59 months, attending a secondary care hospital. Settings and Design: Children were recruited from pediatrics OPD of the sub-district hospital (SDH), Ballabgarh, Haryana, through systematic random sampling. Hemoglobin was measured by an automated analyzer. Serum cobalamin and serum folate were estimated using enhanced chemiluminescence based immunoassay. Results: A total of 420 children were recruited, of which 392 provided a blood specimen. Prevalence of cobalamin, folate deficiency, and anemia were 22.3% (95% CI: 18.3–26.7), 10.9% (95% CI: 8.2–14.6), and 81.9% (95% CI 77.7–85.4), respectively. The proportion of children with cobalamin deficiency who had anemia was 97.7% compared to 95.7% among those with no cobalamin deficiency (P = 0.396). Similarly, the proportion of children with folate deficiency who had anemia was 95.2% compared to 96.2% among those with no folate deficiency (P = 0.765). Conclusion: We found that almost one in five children aged 6–59 were deficient in cobalamin, and one in ten were deficient in folate.

Abstract
BACKGROUND It is thought that there is a high risk of zinc deficiency in India, but there are no representative national estimates. OBJECTIVES We aimed to evaluate the national and state-level prevalence of low serum zinc concentrations (SZCs) in Indian children from the nationally representative Comprehensive National Nutrition Survey. METHODS Prevalence of low SZC, adjusted for C-reactive protein, was estimated among preschool (1-4 y; n = 7874) and school-age children (5-9 y; n = 10,430) and adolescents (10-19 y; n = 10,140), using SZC cutoffs defined by the International Zinc Nutrition Consultative Group. RESULTS Prevalence of low SZC was high among adolescents (31.1%; 95% CI: 29.8%, 32.4%), compared with school-age (15.8%; 95% CI: 15.3%, 16.3%) or preschool children (17.4%; 95% CI: 16.7%, 18.0%). However, stratification of prevalence by fasting status or using an alternative lower SZC cutoff independent of fasting status led to a reduction in prevalence by 3.7% or 7.8% in children <10 y, respectively. The prevalence of low SZC was higher among rural preschool children, those belonging to households with poor socioeconomic status, and those with severe stunting or underweight. Preschool children with diarrhea (22.6%; 95% CI: 20.8%, 24.4%), productive cough (22.7%; 95% CI: 18.5%, 27.5%), or malaria/dengue (38.5%; 95% CI: 29.4%, 48.2%) in the 2 wk preceding the survey had a higher prevalence of low SZC than those without morbidity (16.5%; 95% CI: 15.9%, 17.2%; 17.6%; 95% CI: 16.9%, 18.2%; and 17.5%; 95% CI: 16.8%, 18.1%, respectively). CONCLUSIONS The national prevalence of low SZC among preschool (17%) or school-age children (16%) was <20%, which is considered the cutoff indicating a problem of public health significance; but there were variations by state and socioeconomic status. In adolescents, however, the prevalence of low SZC was 31%, which warrants further investigation. The association of low SZC with diarrhea in preschool children necessitates better coverage of Zn administration in the management of diarrhea.

Abstract
Anemia has been acknowledged as worldwide problem, including in Indonesia. This cross-sectional study aims to explore dietary determinants as risk factors for anemia in children aged 6–36 months living in a poor urban area of Jakarta. The study was done in Kampung Melayu sub-district in Jakarta, Indonesia. Data was collected within two weeks in September–October 2020. A structured questionnaire for a 24-h recall and a semi-quantitative Food Frequency Questionnaire (FFQ) were used to collect the dietary intake data, and venous blood was withdrawn to determine the hemoglobin levels. Bivariate chi-square and multiple logistic regression tests were executed to explore the dietary determinant factors for anemia. We recruited 180 subjects. The average hemoglobin concentration was 11.4 ± 1.7 mg/dL; the anemia prevalence was 29.4%. The following variables were significantly associated with higher risk of anemia: no cow’s milk formula consumption, inadequate intake of fats, protein, calcium, vitamin D, iron, zinc, vitamin A, vitamin C, vitamin B6, and vitamin B12. Only cow’s milk formula consumption and zinc intake were revealed as the determinant factors of anemia. In conclusion, the prevalence of anemia was 29.4% among children aged 6–36 months old. Anemia was significantly associated with two dietary determinants as risk factors that are cow’s milk formula consumption and zinc intake.

Abstract
Adequate iron intake is essential for optimal child development, but iron deficiency and anemia among infants and young children are widespread in low- and middle-income countries. Large-scale food fortification strategies hold great promise for reducing micronutrient deficiencies; however, for children <2 y of age, the impact of such strategies is limited because their intake of staple foods is relatively low and fortification levels are targeted at the adult population. Iron supplementation, iron fortification of foods targeted to infants, and point-of-use fortification with iron-containing products such as multiple micronutrient powders (MNPs) and small-quantity lipid-based nutrient supplements are evidence-based approaches recommended to reduce anemia among infants and young children when used in the right context. Since 2003, the WHO, with support from UNICEF, has recommended the use of MNPs to control iron deficiency. However, the percentage of children with anemia has changed very little over the past 10 y. Five years ago the UN declared a decade of action on nutrition, including World Health Assembly (WHA) targets for maternal, infant, and young child nutrition, yet the WHA set no anemia targets for children. In July 2020 the leaders of 4 UN agencies issued a call for action to protect children's right to nutrition in the face of the COVID-19 pandemic and beyond. Given persistently high rates of anemia among young children, the negative developmental impact, the challenge of meeting iron needs from typical complementary food diets, and the availability of successful evidence-based fortification strategies for this age group, we encourage planners, speakers, and donors at this year's UN Food Systems Summit and the Tokyo Nutrition for Growth Summit to 1) call for the WHA to set anemia targets for infants and young children and 2) promote investment in evidence-based interventions to improve the iron status of young children.

Vitamin A deficiency among children younger than 5 y in India: an analysis of national data sets to reflect on the need for vitamin A supplementation. Am J Clin Nutr 2021; 113:939-947. [PMID: 33330941 DOI: 10.1093/ajcn/nqaa314] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 10/07/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Biochemical vitamin A deficiency (VAD) is believed to be a serious public health problem (low serum retinol prevalence >20%) in Indian children, justifying universal high-dose vitamin A supplementation (VAS). OBJECTIVE To evaluate in Indian children younger than 5 y the risk of biochemical VAD from the Comprehensive National Nutrition Survey, as well as dietary vitamin A inadequacy and excess over the tolerable upper limit of intake (TUL) from national and subnational surveys, factoring in fortification and VAS. METHODS Child serum retinol data, corrected for inflammation, were examined to evaluate national- and state-level prevalence of VAD. Simultaneously, dietary intakes from the National Sample Survey Office and the National Nutrition Monitoring Bureau were examined for risk of dietary vitamin A deficiency against its average requirement (AR) derived for Indian children. Theoretical estimates of risk reduction with oil and milk vitamin A fortification were evaluated along with the risk of exceeding the TUL, as well as when combined with intake from VAS. RESULTS The national prevalence of biochemical VAD measured in 9563 children was 15.7% (95% CI: 15.2%, 16.3%), and only 3 states had prevalence significantly >20%. The AR of vitamin A was 198 and 191 µg/d for boys and girls; the risk of dietary inadequacy was ∼70%, which reduced to 25% with oil and milk fortification. Then, the risk of exceeding the TUL was 2% and 1% in 1- to 3-y-old and 4- to 5-y-old children, respectively, but when the VAS dose was added to this intake in a cumulative 6-mo framework, the risk of exceeding the TUL rose to 30% and 8%, respectively. CONCLUSION The national prevalence of VAD risk is below 20% in Indian children. Because there is risk of excess intake with food fortification and VAS, serious consideration should be given to a targeted approach in place of the universal VAS program in India.

Abstract
OBJECTIVE This study tested the hypothesis that systemic inflammation is inversely associated with haemoglobin levels in adolescent girls in India. METHODS The study population consisted of adolescent girls aged between 10 and 19 years living in a remote rural region in Maharashtra State, India. Data were collected on anthropometric measures, and a venous blood sample was taken and tested for complete blood count and C-reactive protein (CRP). RESULTS Of 679 individuals who were invited to the research site to participate, data were available from 401 participants giving a response rate of 59%. Median blood CRP was 1.26 mg/l (Range 0.00 to 26.33), and 167 (41.6%) participants had CRP level < 1.0 mg/l. The mean haemoglobin was 12.24 g/dl (standard deviation [SD] 1.51), and the mean total white blood cells (WBC) count was 9.02 × 103 /μl (SD 2.00). With each g/dl increase in blood haemoglobin, the risk of having an elevated CRP of ≥ 1 mg/l increased with an odds ratio of 1.16 (95% CI 1.01 to 1.33, P = 0.03). Total WBC count was also positively associated with blood haemoglobin, increasing by 0.24 × 103 /μl (95% CI 0.11 to 0.37, P < 0.001) per g/dl increase in haemoglobin. Both analyses were adjusted for age. CONCLUSIONS In this population, blood haemoglobin levels were positively associated with two measures of systemic inflammation, contrary to the primary hypothesis being tested. Other unmeasured environmental exposures may modify haemoglobin levels in this population. Understanding this observation may help design better public health interventions to improve the well-being of adolescent girls in India.

Abstract
BACKGROUND Vitamin B12 deficiency is prevalent worldwide especially in vegetarian communities. Its deficiency in early childhood may result in serious neurological and cognitive deficits. It is important to know the prevalence among our infants and toddlers so that nutritional policy changes could be suggested in this regard. OBJECTIVE To evaluate the vitamin B12 status of apparently healthy Indian children between 6 and 23 months of age. METHODS Apparently healthy Indian children (n = 210), of age 6 to 23 months, attending pediatric outpatient department were recruited and samples obtained to evaluate their hemogram and levels of vitamin B12, folate, and ferritin. Data were analyzed to obtain the mean levels and the proportion of participants deficient in vitamin B12. The dietary habits of the children were also analyzed and correlated with their vitamin B12 status. RESULTS Vitamin B12 deficiency was observed in 37.6% of the participants. CONCLUSIONS There is a high prevalence of vitamin B12 deficiency in our infants and toddlers, and there is need to initiate supplement to prevent any possible neurological consequences. Early initiation of animal milk had a positive effect on the vitamin B12 status of the child, though it was not significant.

Anemia prevalence, severity and associated factors among children aged 6-71 months in rural Hunan Province, China: a community-based cross-sectional study. BMC Public Health 2020; 20:989. [PMID: 32576157 PMCID: PMC7310416 DOI: 10.1186/s12889-020-09129-y] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Accepted: 06/16/2020] [Indexed: 11/28/2022] Open
Abstract
Background In recent 10 years, with the rapid socioeconomic development and the extensive implementation of children nutrition improvement projects, the previous epidemiological data cannot reflect the actual level of anemia among children in China, especially in rural areas. Therefore, this study analyzed the prevalence, severity and associated factors of anemia among children aged 6–71 months in rural Hunan Province. Methods A community-based cross-sectional study was conducted. Through multistage stratified cluster sampling, 5229 children aged 6 to 71 months and their caregivers were randomly selected from 72 villages across 24 towns in 12 counties from rural Hunan. The demographic characteristics of children and their caregivers, feeding practice, nutritional status of children, caregivers’ anemia-related feeding knowledge, and gestational conditions of mothers were acquired by using a unified questionnaire. Peripheral blood from the left-hand middle fingertip was sampled from each child, and hemoglobin concentration was measured using a HemoCue301 portable hemoglobin analyzer (Sweden). Associated factors analyses involving overall anemia and anemia severities were conducted on multivariate logistic regression models. Results The overall anemia prevalence was 8.8%, and the prevalence of mild, moderate and severe anemia was 6.3, 2.5 and 0.1%, respectively. Children age groups of 6–11 months, 12–23 months and 36–47 months, exclusive breast-feeding within 6 months after birth, and maternal moderate/severe anemia were significantly associated with an increased risk of overall anemia in children. Children age groups of 6–11 months and 12–23 months were significantly associated with an increased risk of mild anemia in children. Children age groups of 6–11 months, 12–23 months and 36–47 months, low caregivers’ anemia-related feeding knowledge level, and maternal moderate/severe anemia were significantly associated with an increased risk of moderate/severe anemia in children. Children who underwent regular physical examination were less likely to have moderate/severe anemia. The common protective factor for overall, mild and moderate/severe anemia in children was high family income. Conclusions The anemia status of preschool children in rural Hunan Province was a mild public health problem and associated with children age group, feeding practice, regular physical examination, family income, caregivers’ anemia-related feeding knowledge level, and maternal moderate/severe anemia.

Prevalence of Undernutrition and Anemia among Santal Adivasi Children, Birbhum District, West Bengal, India. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17010342. [PMID: 31947849 PMCID: PMC6981430 DOI: 10.3390/ijerph17010342] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/03/2019] [Revised: 12/23/2019] [Accepted: 12/28/2019] [Indexed: 02/07/2023]
Abstract
India’s Adivasi scheduled tribe population is disproportionately affected by undernutrition and anemia, thereby prevailing in the poorest wealth deciles denominated as socially and economically vulnerable. This study was designed to assess the extent of child undernutrition (conventional and composite index of anthropometric failure (CIAF) classification), as well as the burden of anemia in children and its independent nutrition specific and sensitive drivers, moreover to reflect the living conditions of Santal Adivasis. The research survey was conducted in 21 Santal villages, Birbhum District, West Bengal, in 2015. An overall 307 children (aged 6–39 months) and their mothers (n = 288) were assessed for their hemoglobin (Hb) levels (HemoCue Hb201+) and anthropometric indices such as height/length, weight and mid-upper arm circumference (MUAC). Moreover, socio-demographic household characteristics were surveyed. The study confirmed Adivasi children lagging behind national average with a high prevalence of undernutrition (height-for-age z-score (HAZ) 51.9%, weight-for-age z-score (WAZ) 49.2%, weight-for-height z-score WHZ 19.0% and CIAF 61.6%) and of moderate and severe anemia (Hb < 10 g/dL, 73.3% altogether). Child’s age <24 months, low WAZ scores, morbidity (any fever, diarrhea or respiratory infection) on the checkup day or during previous week, low maternal Hb level, and lack of dietary diversification were identified as predictors for anemia, thereby warrant targeted interventions to decrease the high anemia rates assessed in the study site.
