Nutritional deficiencies in the pediatric age group in a multicultural developed country, Israel

The Physical Developmental Characterization of Children with Nutritional Deficiencies and Attributed Specific Categories

BACKGROUND

There are few studies examining the physical developmental phenotypes of nutritional deficiency diseases (NDDs) among Chinese children aged 1-7 years by anthropometrics and clarifying the specific NDD categories that caused growth faltering.

METHODS

A total of 3054 cases of NDDs in children aged 1-7 years were investigated. The age, height, and weight of children with NDDs were adjusted by using the skewness coefficient-median-coefficient of variation method, and the results were compared with the WHO standardized level. Comparisons of specific categories of NDDs were performed with respect to the age-specific height standardized values (HAZ), the age-specific weight standardized values (WAZ), and the age-specific body mass index standard values (BAZ).

RESULT

The subtypes of NDDs among Chinese children were mainly characterized by single and co-morbid deficiencies. Calcium deficiency, vitamin A deficiency, vitamin D deficiency, and vitamin B deficiency were the main types, accounting for 11.33%, 9.26%, 8.70%, and 6.29% of the total confirmed cases, respectively; protein-energy malnutrition combined with vitamin C deficiency was the most common type of combined nutrient deficiency (5.76%). The HAZ (-0.0002), WAZ (-0.0210), and BAZ (-0.0018) of children aged 1-3 years with NDDs was lower than the WHO standard (0), as were the HAZ (-0.0003), WAZ (-0.0219), and BAZ (-0.0019) of children aged 3-7 years. The anthropometrics of children with NDDs aged 1-7 years showed that the HAZ and BAZ were slightly lower than the WHO average level, whereas the WAZ was significantly different from the WHO average. The co-morbidity of vitamin A deficiency and vitamin D deficiency, calcium deficiency and vitamin C deficiency, vitamin D deficiency and vitamin C deficiency, and iodine deficiency and vitamin C deficiency were associated with the WAZ.

INTERPRETATION

The specific categories of NDDs consist mainly of calcium deficiencies, vitamin A deficiencies, and vitamin D deficiencies. The main signs of growth retardation were low weight and height, which were driven by the specific single and co-morbid micronutrient deficiencies.

Low utility of serum folic acid blood tests in healthy children and adolescents, a nationwide cohort

This study aimed to evaluate the utility of serum folic acid testing in children and adolescents in a developed country without mandatory folic acid food fortification and to identify patients at risk for folic acid deficiency. In this cross-sectional study, records from primary care and hospitals were reviewed for patients aged 0-18 years who underwent serum folic acid testing. Data were retrieved from the Leumit-Health-Services database over a ten-year period (January 2008 to December 2018). Clinical and laboratory data were compared between patients with folic acid deficiency to those with normal levels. Among 20,411 pediatric patients tested, 884 (4.3%) had folic acid deficiency, of whom only 26.3% had anemia. Only two patients (0.2%) had megaloblastic anemia. Multivariate analysis showed that male gender (odds ratio(OR)1.6, 95% CI 1.22-2.12), older age (OR 1.32, 95% CI 1.26-1.39), higher BMI percentile (OR 1.01, 95% CI 1-1.01), antipsychotic treatment (OR 3.23, 95% CI 1.52-6.84), celiac (OR 2.97, 95% CI 1.66-5.34), and Attention-Deficit-and-Hyperactivity-Disease (ADHD) treated with psychostimulants (OR 2.21, 95% CI 1.56-3.12) were associated with folic acid deficiency(all p < 0.01). Lower hemoglobin levels were independently associated with increased OR of folic acid deficiency (OR 0.77, 95% CI 0.66-0.90, p = 0.001), but anemia as a diagnosis was not.

CONCLUSION

Pediatric folic acid deficiency rates were low in this nationwide cohort and not linked to megaloblastic anemia, likely due to concomitant iron deficiency anemia. Although retrospective, this might suggest low utility for routine serum folic acid testing in healthy children in developed countries, except in cases of celiac disease or specific medication use such psychostimulants or antipsychotics.

WHAT IS KNOWN

• Folic acid deficiency is common among children in developing countries, causing megaloblastic anemia, growth delays, and cognitive impairments. In developed countries, the prevalence is considered low.

WHAT IS NEW

• Of 20,411 pediatric patients tested for serum folate, in a developed country, only 4.3% had folate deficiency. • Risk factors for deficiency included celiac, antipsychotics, and psychostimulant treatment for ADHD. • Routine folate testing in developed countries may have limited utility; Targeted screening is recommended.

The relationship between nutrition and micronutrients in healthy Turkish infants and young children

BACKGROUND

A healthy diet is important at every stage of life. We aimed to determine the serum vitamin D and iron, folic acid, and vitamin B12 levels in healthy children younger than 48 months and to investigate the relationship between nutrition and micronutrients in children of this age.

METHODS

In this observational study children who presented to the Pediatrics Clinic of our hospital during the period 2015-2022 were included. Vitamin D and other nutritional parameters (serum folate, vitamin B12, iron, ferritin) were evaluated from the study participants' serum samples during the outpatient clinic visit (jaundice check-up, pre-circumcision surgery, etc.).

RESULTS

Overall, 766 cases were included in the study. Vitamin D was higher in the group that was fed only breast milk (p = 0.019), and vitamin D insufficiency was statistically higher in the formula group (p = 0.015). Hemoglobin levels were significantly higher in the formula group (p = 0.007). The folic acid level was found to be normal in all infants, and was higher in formula-fed infants (p = 0.012). Vitamin B12 was found to be significantly higher in infants fed with formula (p = 0.001). Vitamin D deficiency was most common in infants aged 25-48 months (p < 0.001). Similarly, vitamin D insufficiency (12-20 ng/mL) was detected in infants aged between 25 and 48 months (p < 0.001).

CONCLUSION

Micronutrients such as calcium, folic acid, iron, vitamin D, and iodine are critical in early fetal development from pregnancy onward. It is vital to raise awareness of this issue for mothers, starting from pregnancy, and for mothers to feed their babies more carefully in the first years of life.

Dietary intake of folate and the frequency of its deficiency in children with type 1 diabetes mellitus and healthy children

Adequate folate intake is essential for a child’s growth. There is lack of information about the prevalence of this nutrient deficiency in the Ukrainian population, including children. The aim of the study was to evaluate the dietary intake of folate and determine the frequency of folate deficiency in children with Type 1 diabetes mellitus (T1D) and healthy children. Determination of folate in serum was performed by ELISA. Folate level <3 ng/ml was diagnosed as a folate deficiency. Among all observed children the folate deficiency was diagnosed in 23 (32.9%): in 6 (17.1%) patients with T1D and in 17 (48.6%) healthy children (P ≤ 0.01). The mean level of serum folate in patients with T1D was (5.09 ± 2.16) ng/ml and (3.72 ± 1.87) ng/ml in healthy children (P ≤ 0.01). The average daily intake of folate with food was (138.68 ± 70.37) µg, without difference between T1D (12.00 ± 3.51 yr.) and healthy groups (10.83 ± 3.24 yr.), and it was more than two times lower than age requirements (300 µg/day). However, it was self-reported that 15 (48.9%) children of T1D group received vitamin supplementation one time in six months, while in healthy children only 6 (17.1%) children received vitamins (P ≤ 0.01). In conclusion, the frequency of folate deficiency is high in the pediatric population. Nutrition does not provide the necessary intake of folate, which indicates the need for additional folate supplementation. Keywords: children., deficiency, diabetes mellitus, dietary intake, folate

Comparison between School-Age Children with and without Obesity in Nutritional and Inflammation Biomarkers

Childhood obesity is a major health problem. We examined differences between children with obesity and normal weight in nutritional and inflammation biomarkers. A cross-sectional study was conducted among healthy children aged 10-12 years from Arab villages in Israel. Parents were interviewed regarding sociodemographic and children's health status. Body weight and height measurements were performed and weight categories were defined using the 2007 WHO growth curves. Blood samples were tested for complete blood count, levels of iron, ferritin, lipids, uric acid, and C-reactive protein (CRP). Overall, 146 children (59.0% males, mean age = 11.3 [SD = 0.5]) were enrolled. In total 43.8%, 14.1% and 42.3% of the participants had normal weight, overweight and obesity, respectively. A multivariable logistic regression model showed that children with overweight and obesity had lower iron, and HDL-C levels than children with normal weight. Levels of CRP, uric acid, LDL-C and lymphocytes were higher among children with overweight and obesity. In conclusion, our findings highlight the worse metabolic and nutritional status in overweight and obese children. Such markers play a role in metabolic syndrome, thus suggesting that metabolic syndrome might start in childhood.

Vitamin D Levels in Ethnic Minority Adolescents in Primary Care

INTRODUCTION

This pilot study examined the distribution of low vitamin D levels among ethnic minority adolescents in primary care to elucidate the clinical needs of this diverse population.

METHOD

A cross-sectional study was conducted using a retrospective patient chart review. Participants were a consecutive sample of 119 ethnically diverse adolescents aged 12-18 years, attending a primary care clinic, who had a wellness examination in 2018 and documented vitamin D levels on the basis of previously collected blood work.

RESULTS

Sixty-one percent of adolescents had low vitamin D levels. Vitamin D deficiency increased with age, independently of ethnicity or gender.

DISCUSSION

A significant number of ethnically diverse adolescents presented with low vitamin D levels. A need exists to raise awareness among clinicians regarding social determinants of health and culturally sensitive dietary practices to improve vitamin D levels and prevent long-term complications, focusing on adolescent at-risk ethnic groups.

Complementary feeding pattern and its determinants among mothers in selected primary health centers in the urban metropolis of Ekiti State, Nigeria

The incidence of malnutrition in the first two years of life has been directly linked with inappropriate complementary feeding practices along with high infectious disease levels. This study was therefore aimed to assess the complementary feeding pattern among mothers of children aged zero to two years in selected health centres in Ado Ekiti, the capital of Ekiti State, Nigeria. The study was cross-sectional in design. One hundred and thirty-five mothers were selected from two health centres within Ado-Ekiti for this study. A semi-structured interviewer-administered questionnaire was used to collect information from the mothers. The questionnaire included questions that assessed the mothers’ socio-demographic characteristics and complementary feeding pattern. Most (62.5%) infants were introduced to complementary foods at 3–5 months old and water (43.3%) at 3 months of age. The main food item given to the infants on commencement of complementary feeding was formula food (45.9%) followed by fermented cereal gruel (37%). The timing of introduction for different food items revealed that in contrast to the use of fermented cereal gruel (23.8%), fewer children were introduced to iron-rich foods (15.1%) and fruits (11%) at 6 months to a year old. Mother’s knowledge of ideal age for the introduction of complementary feeding (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\chi }^{2}=$$\end{document}χ2= 20.547; p < 0.001) associated significantly with the age of introduction of complementary feeding. More than three-fifth (62.5%) of the respondents had commenced complementary feeding to their infants between 3 and 5 months while an excess of two-fifth (43.3%) of the respondents started giving their children water to drink at 3 months of age. Nurses and nutritionists in primary health care centers should take the lead role in educating mothers about the need for exclusive breastfeeding for the first 6 months of life and appropriate complementary feeding for ages 6–24 months.

Epidemiology of Gastrointestinal Disease among Children and Adolescents in Kazakhstan: 2012–2019

BACKGROUND: Gastrointestinal diseases are important trigger of public health concern in pediatric population. Non treated pathologies led to chronic inflammatory processes in adulthood. AIM: With respect to the lack of international studies on epidemiology of gastrointestinal disease in pediatric population, this study was aimed at analysis of national and local incidence rates of gastrointestinal disorders among children and adolescents in Kazakhstan over the period from 2012 to 2019. METHODS: This was a retrospective cross-sectional study located on South part of Kazakhstan and based on the data obtained from the Republican Center for Health Development – the major data source on the country’s health statistics. From this, we extracted information on children (0–14 years) and adolescents (15–17 years) with gastrointestinal disease (K00-K95 International Classification of Diseases, Revision 10 codes). We calculated incidence rates for the whole country and Turkestan province. RESULTS: The national incidence of pediatric disease was characterized by relative stability, and was 7760.4 per 100,000 population in 2017. The incidence of peptic ulcers and gallbladder disease in adolescents substantially exceeded that in children. At provincial level the incidence of gastritis/duodenitis and peptic ulcers was gradually declining, while that of gallbladder disease was subjected to growth over the past years. Adolescents had higher rates of gastrointestinal disease both at national and provincial levels. CONCLUSION: The analysis of national and local incidence rates of gastrointestinal disorders among children and adolescents in Kazakhstan showed that more studies are needed to obtain in-depth understanding of risk factors associated with gastrointestinal disease in child and adolescent population of Kazakhstan, including the prevalence of Helicobacter pylori infection. Besides, a national registry on pediatric gastrointestinal disease should be envisaged to overcome the lack of essential data.

Celiac disease in the COVID-19 pandemic

Background

The COVID-19 pandemic has had an impact on global health.

Design

The impact of the COVID-19 pandemic on patients with coeliac disease was assessed in the present review.

Results

The incidence of coeliac disease and the problems associated with coeliac disease increased during the COVID-19 pandemic. Adherence to the diet is crucial for the patient's health and quality of life since the only approved therapy for coeliac disease is a gluten withdrawal.

Conclusions

A gluten-free diet should be promoted by the therapeutic team and implemented among these categories of patients.

•

Health education to follow the GFD does not exist in many countries. Unfortunately, the COVID-19 pandemic has increased psychological problems among patients with CD.

•

The association of T1D with CD has been and remains a problem in CD management.

•

Associating IBD with CD is again a challenge. Psychological problems also appeared in the associations of CD with T1D and IBD. The COVID-19 virus did not pose an increased risk to CD patients, but the COVID-19 pandemic brought many psychological problems to CD patients.

•

CD patients should adhere to GFD, in general, hence pay attention to gluten withdrawal during the COVID-19 pandemics, to avoid other complications and improve their QOL.

Food fortification with multiple micronutrients: impact on health outcomes in general population

BACKGROUND

Vitamins and minerals are essential for growth and maintenance of a healthy body, and have a role in the functioning of almost every organ. Multiple interventions have been designed to improve micronutrient deficiency, and food fortification is one of them.

OBJECTIVES

To assess the impact of food fortification with multiple micronutrients on health outcomes in the general population, including men, women and children.

SEARCH METHODS

We searched electronic databases up to 29 August 2018, including the Cochrane Central Register of Controlled Trial (CENTRAL), the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register and Cochrane Public Health Specialised Register; MEDLINE; Embase, and 20 other databases, including clinical trial registries. There were no date or language restrictions. We checked reference lists of included studies and relevant systematic reviews for additional papers to be considered for inclusion.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), cluster-RCTs, quasi-randomised trials, controlled before-after (CBA) studies and interrupted time series (ITS) studies that assessed the impact of food fortification with multiple micronutrients (MMNs). Primary outcomes included anaemia, micronutrient deficiencies, anthropometric measures, morbidity, all-cause mortality and cause-specific mortality. Secondary outcomes included potential adverse outcomes, serum concentration of specific micronutrients, serum haemoglobin levels and neurodevelopmental and cognitive outcomes. We included food fortification studies from both high-income and low- and middle-income countries (LMICs).

DATA COLLECTION AND ANALYSIS

Two review authors independently screened, extracted and quality-appraised the data from eligible studies. We carried out statistical analysis using Review Manager 5 software. We used random-effects meta-analysis for combining data, as the characteristics of study participants and interventions differed significantly. We set out the main findings of the review in 'Summary of findings' tables, using the GRADE approach.

MAIN RESULTS

We identified 127 studies as relevant through title/abstract screening, and included 43 studies (48 papers) with 19,585 participants (17,878 children) in the review. All the included studies except three compared MMN fortification with placebo/no intervention. Two studies compared MMN fortification versus iodised salt and one study compared MMN fortification versus calcium fortification alone. Thirty-six studies targeted children; 20 studies were conducted in LMICs. Food vehicles used included staple foods, such as rice and flour; dairy products, including milk and yogurt; non-dairy beverages; biscuits; spreads; and salt. Fourteen of the studies were fully commercially funded, 13 had partial-commercial funding, 14 had non-commercial funding and two studies did not specify the source of funding. We rated all the evidence as of low to very low quality due to study limitations, imprecision, high heterogeneity and small sample size. When compared with placebo/no intervention, MMN fortification may reduce anaemia by 32% (risk ratio (RR) 0.68, 95% confidence interval (CI) 0.56 to 0.84; 11 studies, 3746 participants; low-quality evidence), iron deficiency anaemia by 72% (RR 0.28, 95% CI 0.19 to 0.39; 6 studies, 2189 participants; low-quality evidence), iron deficiency by 56% (RR 0.44, 95% CI 0.32 to 0.60; 11 studies, 3289 participants; low-quality evidence); vitamin A deficiency by 58% (RR 0.42, 95% CI 0.28 to 0.62; 6 studies, 1482 participants; low-quality evidence), vitamin B2 deficiency by 64% (RR 0.36, 95% CI 0.19 to 0.68; 1 study, 296 participants; low-quality evidence), vitamin B6 deficiency by 91% (RR 0.09, 95% CI 0.02 to 0.38; 2 studies, 301 participants; low-quality evidence), vitamin B12 deficiency by 58% (RR 0.42, 95% CI 0.25 to 0.71; 3 studies, 728 participants; low-quality evidence), weight-for-age z-scores (WAZ) (mean difference (MD) 0.1, 95% CI 0.02 to 0.17; 8 studies, 2889 participants; low-quality evidence) and weight-for-height/length z-score (WHZ/WLZ) (MD 0.1, 95% CI 0.02 to 0.18; 6 studies, 1758 participants; low-quality evidence). We are uncertain about the effect of MMN fortification on zinc deficiency (RR 0.84, 95% CI 0.65 to 1.08; 5 studies, 1490 participants; low-quality evidence) and height/length-for-age z-score (HAZ/LAZ) (MD 0.09, 95% CI 0.01 to 0.18; 8 studies, 2889 participants; low-quality evidence). Most of the studies in this comparison were conducted in children. Subgroup analyses of funding sources (commercial versus non-commercial) and duration of intervention did not demonstrate any difference in effects, although this was a relatively small number of studies and the possible association between commercial funding and increased effect estimates has been demonstrated in the wider health literature. We could not conduct subgroup analysis by food vehicle and funding; since there were too few studies in each subgroup to draw any meaningful conclusions. When we compared MMNs versus iodised salt, we are uncertain about the effect of MMN fortification on anaemia (R 0.86, 95% CI 0.37 to 2.01; 1 study, 88 participants; very low-quality evidence), iron deficiency anaemia (RR 0.40, 95% CI 0.09 to 1.83; 2 studies, 245 participants; very low-quality evidence), iron deficiency (RR 0.98, 95% CI 0.82 to 1.17; 1 study, 88 participants; very low-quality evidence) and vitamin A deficiency (RR 0.19, 95% CI 0.07 to 0.55; 2 studies, 363 participants; very low-quality evidence). Both of the studies were conducted in children. Only one study conducted in children compared MMN fortification versus calcium fortification. None of the primary outcomes were reported in the study. None of the included studies reported on morbidity, adverse events, all-cause or cause-specific mortality.

AUTHORS' CONCLUSIONS

The evidence from this review suggests that MMN fortification when compared to placebo/no intervention may reduce anaemia, iron deficiency anaemia and micronutrient deficiencies (iron, vitamin A, vitamin B2 and vitamin B6). We are uncertain of the effect of MMN fortification on anthropometric measures (HAZ/LAZ, WAZ and WHZ/WLZ). There are no data to suggest possible adverse effects of MMN fortification, and we could not draw reliable conclusions from various subgroup analyses due to a limited number of studies in each subgroup. We remain cautious about the level of commercial funding in this field, and the possibility that this may be associated with higher effect estimates, although subgroup analysis in this review did not demonstrate any impact of commercial funding. These findings are subject to study limitations, imprecision, high heterogeneity and small sample sizes, and we rated most of the evidence low to very low quality. and hence no concrete conclusions could be drawn from the findings of this review.
