Reducing infantile anemia: insight on patterns of process and outcome indicators by ethnicity and socioeconomic class during a 10-year intervention program and 5 years after

Background

In 2005, Clalit Health Services (CHS), the largest health maintenance organization in Israel, initiated an intervention program aimed at reducing the prevalence rate of infantile anemia (IA). This study evaluated the progress made during the intervention (2005–2014) and its yield 5 years after it ended (2019).

Methods

The CHS database was retrospectively reviewed twice yearly from 2005 to 2014 for repetitive samples of children aged 9 to 18 months regarding the previous half-year interval, and a single sample in 2019. Data were collected on gender, ethnicity (Jewish/non-Jewish), socioeconomic class (SEC; low/intermediate/high), hemoglobin testing (yes/no), and hemoglobin level (if tested). Excluded were infants with documented or suspected hemoglobinopathy.

Results

At study initiation, the rate of performance of hemoglobin testing was 54.7%, and the IA prevalence rate was 7.8%. The performance rate was lower in the Jewish than the non-Jewish subpopulation. The low-SEC subpopulation had a similar hemoglobin testing rate to the high-SEC subpopulation but double the IA prevalence rate. Overall, by the end of the intervention (2014), the performance rate increased to 87.5%, and the AI prevalence rate decreased to 3.4%. In 2019, there was little change in the performance rate from the end of the intervention (88%) and the IA prevalence was further reduced to 2.7%. The non-Jewish and low-SEC subpopulations showed the most improvement which was maintained and even bettered 5 years after the intervention ended.

Conclusions

The 10-year IA intervention program introduced by CHS in 2005 led to a reduction in IA prevalence rate to about 3.5% in all sub-populations evaluated. By program end, the results in the weaker subpopulations, which had the highest prevalence of IA at baseline, were not inferior to those in the stronger subpopulations. We recommended to the Israel Ministry of Health to adopt the intervention countrywide, and we challenge other countries to consider similar interventions.

Is High Milk Intake Good for Children's Health? A National Population-Based Observational Cohort Study

Milk is widely considered as a beneficial product for growing children. This study was designed to describe the milk consumption status of Korean children aged 30–36 months and to investigate its association with the risk of obesity and iron deficiency anemia (IDA). This nationwide administrative study used data from the Korean national health insurance system and child health screening examinations for children born in 2008 and 2009. In total, 425,583 children were included, and they were divided into three groups based on daily milk consumption: low milk group (do not drink or drink <200 mL milk per day, n = 139,659), reference group (drink 200–499 mL milk per day, n = 255,670), and high milk group (drink ≥500 mL milk per day, n = 30,254). After adjusting variable confounding factors, the consumption of a large amount of milk of ≥500 mL per day at the age of 30–36 months was associated with an increased risk of obesity at the age of 42–72 months and IDA after the age of 30 months. These results may provide partial evidence for dietary guidelines for milk consumption in children that are conducive to health.

Dietary Determinants of Anemia in Children Aged 6-36 Months: A Cross-Sectional Study in Indonesia

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.

The Consequence of Excessive Consumption of Cow's Milk: Protein-Losing Enteropathy with Anasarca in the Course of Iron Deficiency Anemia-Case Reports and a Literature Review

Cow's milk is a key component of a child's diet. While the consumption of even trace amounts can result in allergy to its proteins and/or hypolactasia, excessive cow's milk consumption can result in numerous health complications, including iron deficiency, due to the diet being improperly balanced. Although the incidence of iron deficiency has declined, it remains the most widespread nutritional deficiency globally and the most common cause of anemia. One rare consequence of anemia caused by iron deficiency is protein-losing enteropathy; however, the mechanisms of its development are unclear. The following manuscript, based on a literature review, presents two rare cases of children, a 16-month-old boy and a 2.5-year-old girl, who developed severe microcytic anemia, enteropathy with hypoalbuminemia, and anasarca as a result of excessive cow's milk consumption. It highlights the possible relationship between excessive consumption of cow's milk in children and severe iron deficiency anemia with accompanying hypoalbuminemia; it may also result in serious clinical conditions, even in children that do not demonstrate food hypersensitivity.

Iron-Enriched Nutritional Supplements for the 2030 Pharmacy Shelves

Iron deficiency (ID) affects people of all ages in many countries. Due to intestinal blood loss and reduced iron absorption, ID is a threat to IBD patients, women, and children the most. Current therapies can efficiently recover normal serum transferrin saturation and hemoglobin concentration but may cause several side effects, including intestinal inflammation. ID patients may benefit from innovative nutritional supplements that may satisfy iron needs without side effects. There is a growing interest in new iron-rich superfoods, like algae and mushrooms, which combine antioxidant and anti-inflammatory properties with iron richness.

Camel milk consumption was associated with lower prevalence of anemia among preschool children in rural pastoral districts of Somali, eastern Ethiopia

OBJECTIVE

The aim of this study was to investigate association between consumption of camel milk (CaM) and childhood anemia.

METHODS

A community-based cross-sectional study was conducted with 388 preschool children (24-59 mo of age) in rural pastoral districts of Somali, eastern Ethiopia. We sampled 185 consumers of CaM and 203 who consumed bovine milk (BM). Children were selected from random households with lactating camels or cattle. Hemoglobin (Hb) was measured in the field using a HemoCue instrument. A multivariable logistic regressions model was used in SPSS version 20 to examine association between type of milk consumption and anemia.

RESULTS

Anemia (Hb <11 g/dL) was found in 59.8% of the overall sample, whereas it was 42.7% and 75.4% among CaM and BM consumers, respectively. The odds of anemia among BM consumers (adjusted odds ratio [aOR], 3.12; 95% confidence interval [CI], 1.27-7.66) and children with intestinal parasites (aOR: 3.32; 95% CI, 1.39-7.91) was compared with CaM consumers and children without intestinal parasites, respectively. Increasing age and height-for-age z-score of children were associated with decreased childhood anemia (P < 0.001). Children with anemia consumed a higher volume of BM compared with non-anemic and CaM consumers, too but the consumption was not statistically significant.

CONCLUSION

CaM consumption was associated with lower prevalence of anemia compared with consumption of BM. Promoting use of CaM as complementary food for preschool children in pastoralist areas might be considered an intervention toward reducing anemia.

Hematological Abnormalities and Associated Factors Among Undernourished Under-Five Children Attending University of Gondar Specialized Referral Hospital, Northwest Ethiopia

Introduction

The hematopoietic system is one of the systems which can be affected by malnutrition, leading to impaired production of all blood cell lines. Undernourished children with hematological abnormalities like anemia are at higher risk of mortality. Therefore, this study aimed at determining the magnitude and associated factors of hematological abnormalities among undernourished under-five children attending at the University of Gondar Specialized Referral Hospital, Northwest Ethiopia.

Methods and Materials

An institution-based cross-sectional study was conducted on a total of 251 undernourished under-five children at University of Gondar Specialized Referral Hospital from January to May 2020. A convenient sampling technique was employed to select study participants. Data were collected using a pretested structured questionnaire. Blood samples were collected for complete blood count which were determined by Sysmex KX-21N analyzer. Stool sample was processed via direct wet mount. Thin and thick blood films were examined to assess malaria parasite. The data were entered to EpiData version 4.6.0.0 and analyzed using SPSS version 23 software. Bi-variable and multi-variable binary logistic regression model were fitted to identify factors associated with hematological abnormalities. A p-value <0.05 in the multivariable analysis was considered as statistically significant.

Results

The overall magnitude of anemia, leukocytosis, thrombocytosis, thrombocytopenia, and leukopenia was 53.4%, 26.7%, 23.9%, 8%, and 2.8%, respectively. Being male, age 6-23 months, high birth order, intestinal parasite infection, edema, not eating vegetables and fruits, and paternal occupation were found to be associated with anemia. Only the age of a child was associated with leukocytosis in undernourished children.

Conclusion

The current study demonstrated the predominant existence of anemia, leukocytosis, and thrombocytosis among undernourished under-five children. Therefore, early diagnosis, monitoring and setting intervention strategies for anemia especially among children under two years old are required to prevent further complication.

Association between Consumption of Cow's Milk and Iron Deficiency Anemia in Children: Are There Roles for Hepcidin-25/Ferroportin? A Case-Control Study

Systemic iron homeostasis is regulated by the interaction of the peptide hormone, hepcidin and the iron exporter, ferroportin. The objective was to investigate the relationship between the consumption of cow's milk and iron deficiency anemia in children 2-10 years old and its association with the hepcidin-25 and ferroportin concentrations. The study population consisted of 187 prepubescent children of similar ideal body weight (IBW:90-120%); 82 children with iron deficiency anemia (37girls and 45boys; 4.27 ± 0.28 years) and 105 (47girls and 58boys; 4.25 ± 0.34 years) healthy age-sex-matched controls. Serum fasting hepcidin-25/ferroportin concentrations were measured by enzyme immunoassay in all subjects. Mean cow's milk consumption in the anemic group (373 ± 248 mL/d) tended to be higher than that in the control group (320 ± 226 mL/d), but the result was not statistically significant (p = 0.063).The mean hepcidin-25 level was significantly higher in the anemic group (19.5 ± 18.4 ng/mL) than in the healthy controls (11.0 ± 10.7, p < 0.001). The mean ferroportin level was lower in the anemic group (21.04 ± 5.74 ng/mL) than in the healthy controls (22.68 ± 4.77 ng/ml, p = 0.037). Consuming cow's milk was not associated with IDA in prepubertal children, provided that it was adequately supplemented with iron-enriched foods. We observed a significant increase in hepcidin-25 levels and a decrease in ferroportin levels in children with iron deficiency anemia compared with healthy controls. Children who consumed more cow's milk had higher levels of hepcidin-25. Iron deficiency anemia is not a concern when cow's milk is given to children if the complementary foods are rich in iron.

Too Much of a Good Thing? Cerebral Sinovenous Thrombosis Due to Excessive Milk Intake Associated Anemia

INTRODUCTION

In young children, excessive cow's milk intake causes iron-deficiency anemia, which is associated with hypercoagulable states. We present a case series of 4 toddlers with excessive milk intake iron-deficiency anemia and cerebral sinovenous thrombosis.

METHODS

Retrospective chart review of 4 patients was performed for patients with cerebral sinovenous thrombosis and iron-deficiency anemia secondary to excessive milk intake. Iron-deficiency anemia was defined as hemoglobin <11 mg/dL, mean corpuscular volume <70 fL, and serum ferritin <12 μg/L. Excessive milk intake was defined as consumption of >24 oz daily. Clinical, laboratory, and radiographic features were reviewed.

RESULTS

Age ranged from 12 to 24 months. Average hemoglobin, hematocrit, mean corpuscular volume, and ferritin levels were 6.1 g/dL, 22.7 g/dL, 52.7 fL, and 3.2 ng/mL, respectively. Daily milk consumption ranged from 40 to 60 oz. All patients presented with focal neurologic deficits, including seizures in 3. The location of cerebral sinovenous thrombosis varied, and 3 patients had venous infarcts, one of them hemorrhagic. All patients had a limited diet and were described as "picky eaters" by their parents, and only 1 had transitioned of a bottle. All patients were treated with anticoagulation, iron supplementation, and extensive dietary counseling to reduce cow's milk intake.

CONCLUSION

Iron-deficiency anemia due to excessive milk intake is an important and preventable etiology of pediatric cerebral sinovenous thrombosis. Focused anticipatory guidance is necessary for at-risk groups to prevent this neurologic emergency.
