ABSTRACT
Introduction: Neurologically impaired (NI) children are at risk of malnutrition, which consequently impacts their health and quality of life. Accurate nutrition assessment is an important step in guiding appropriate nutrition support. Conventional anthropometric measurements among NI children have some limitations. Determining body composition requires more complex equipment, which is not routinely performed. This study was conducted to evaluate the association between anthropometric parameters and body composition assessed using the deuterium dilution technique (DDT) in NI children. Methods: A cross-sectional study enrolled severe NI children aged 1-20 years who received home enteral nutrition for at least 3 months. Weight, length, and 4-site skinfold thickness were measured. Body composition was determined using DDT following the International Atomic Energy Agency (IAEA) protocol. Results: A total of 37 NI children (56.76% male, median age 7.2 years) were enrolled. The prevalence of underweight, stunting, and overweight were 22, 38, and 35%, respectively. Body composition analysis showed the mean (SD) of total body water (TBW) and fat mass (FM) were 10.52 (4.51) kg and 9.51 (6.04) kg, respectively. Multivariate GLM analysis showed that the factors associated with FM were age (ß = 0.07 [0.05,0.08]; p < 0.001), body mass index (BMI) (ß = 0.82 [0.52, 1.12]; p < 0.001), biceps skinfold thickness (BSF) (ß = 0.49 [0.23,0.75]; p = 0.001), and subscapular skinfold thickness (SSF) (ß = -0.24 [-0.46,0.03]; p = 0.030). A predictive equation for FM was constructed. Conclusion: A high prevalence of malnutrition was found among severe NI children despite enteral nutrition support. Our findings showed that age, BMI, BSF, and SSF were associated with FM. The predictive equation of FM was proposed and needed to be further validated and applied to clinical practice.
ABSTRACT
BACKGROUND: Promoting and supporting breastfeeding is an important public health intervention with multiple benefits for both infants and mothers. Even modest increases in the prevalence and duration of breastfeeding could significantly reduce healthcare costs and improve maternal and child health outcomes. However, widespread adoption of breastfeeding recommendations remains poor in most settings, which contributes to widening health and social inequalities. Pediatricians have a duty to advocate for improving child health, including promoting and supporting breastfeeding. SUMMARY: This paper, from the International Pediatric Association Special Advisory Group on Nutrition, considers common barriers to breastfeeding and addresses how pediatricians can better promote and support breastfeeding, both at an individual level and by influencing practice and policy. All pediatricians need to understand the basics of breastfeeding, including lactation physiology, recognize common breastfeeding problems, and advise mothers or refer them for appropriate support; training curricula for general pediatricians and all pediatric subspecialties should reflect this. Even in the situation where their day-to-day work does not involve direct contact with mothers and infants, pediatricians can have an important influence on policy and practice. They should support colleagues who work directly with mothers and infants, ensuring that systems and environments are conducive to breastfeeding and, where appropriate, milk expression. Pediatricians and pediatric organizations should also promote policies aimed at promoting and supporting breastfeeding at local, regional, national, and international levels. KEY MESSAGES: Pediatricians have a duty to promote and support breastfeeding, regardless of their day-to-day role and responsibilities. Pediatric training curricula should ensure that all trainees acquire a good understanding of breastfeeding so they are able to effectively support mothers in their personal practice but also influence breastfeeding practice and policy at a local, regional, national, and international level.

Nutrition screening is an essential process to detect children at risk of malnutrition during hospitalization and provide appropriate nutrition management. STRONGkids is a nutrition screening tool which has been implemented in a tertiary-care hospital service in Bangkok, Thailand. This study aimed to evaluate the performance of STRONGkids in the real-situation setting. Electronic Medical Records (EMR) of hospitalized pediatric patients aged 1 month to 18 years from January to December 2019 were reviewed. Those with incomplete medical records and re-admission within 30 days were excluded. Nutrition risk scores and clinical data were collected. Anthropometric data were calculated to Z-score based on the WHO growth standard. The sensitivity (SEN) and specificity (SPE) of STRONGkids were determined against malnutrition status and clinical outcomes. In total, 3914 EMRs (2130 boys, mean age 6.22 ± 4.72 years) were reviewed. The prevalence of acute malnutrition (BMI-for-age Z-score < -2) and stunting (height-for-age Z-score < -2) were 12.9 and 20.5%. SEN and SPE of STRONGkids against acute malnutrition were 63.2 and 55.6%, stunting values were 60.6 and 56.7%, and overall malnutrition values were 59.8 and 58.6%. STRONGkids had low SEN and SPE to detect nutrition risks among hospitalized children in a tertiary-care setting. Further actions are required to improve the quality of nutrition screening in hospital services.
ABSTRACT
Children with developmental and behavioral problems including autistic spectrum disorders (ASDs) may have inappropriate feeding behaviors, which leads to an increased risk of multiple nutrient deficiencies. Vitamin C deficiency is one of the common nutrient deficiencies reported in children with inappropriate feeding. This case report illustrates two cases of ASD children with a clinical presentation of pulmonary arterial hypertension, a rare presentation of vitamin C deficiency. Vitamin C supplementation, pulmonary vasodilator, and supportive treatment were provided. Patients could recover from the illness and could be discharged from the hospital in a short time. In addition to vitamin C, the patients also had multiple micronutrient deficiencies. Nutrition counseling was given and micronutrient supplement was continued until follow-up. Regular nutrition assessment and counseling among children with ASD are needed to prevent nutrient deficiencies which may lead to life-threatening complications.
ABSTRACT
BACKGROUND: Recent research indicates that a number of children with autism generate folate receptor alpha autoantibodies (FRAA), which block transportation of folate across the blood-brain barrier, resulting in cerebral folate deficiency syndrome. Plasma FRAA detection permits precision diagnosis and potentially beneficial folinic acid treatment in FRAA-positive children with autism. OBJECTIVES: To investigate FRAA prevalence in Thai children with autism and evaluate the associations between FRAA-positive status, clinical symptom severity, and adaptive functioning. METHODS: FRAA level was determined in serum samples from 89 children with autism between 2 and 15 years (69 males, 20 females, mean age 7.9 years, SD 3.8). The Childhood Autism Rating Scale-Second Edition (CARS-2) and the Vineland Adaptive Behavior Scales (VABS) were used to evaluate clinical symptom severity and adaptive functioning, respectively. RESULTS: Of 89 children, 30 (33.7%) were FRAA-positive. FRAA-positive children with autism had significantly poorer mean VABS Adaptive Behavior Composite scores (p = 0.02) and Communication scores (p = 0.02) than FRAA-negative children with autism. There was no association between FRAA level and clinical symptom severity (CARS-2 score) (p = 0.09). CONCLUSIONS: The findings demonstrate the presence of FRAA in children with autism and that FRAA status is associated with poorer adaptive functioning.

Neonatal nutrient storage and supplies from breast milk contribute to nutrient status and growth of infants during their early life. This study investigated the adequacy of zinc and iron intakes among breastfed infants during the first 4 months and determined the relative importance of zinc/iron storage versus nutrient intakes with infant's biochemical status and growth. A longitudinal study followed lactating women and their breastfed infants from birth to 4 months postpartum. Cord zinc and ferritin concentrations, as indicators of nutrient storages, were determined. Zinc and iron intakes from breast milk were determined by measurement of breast milk volume together with milk zinc and iron concentrations at 2 and 4 months postpartum. Inadequacy of nutrient intakes was determined using average requirement (AR) which were 1.6 and 0.24 mg/day for zinc and iron respectively. Infant's serum zinc and ferritin were determined at 4 months of age. The data were collected from 64 and 56 participants at 2 months and 4 months postpartum. Inadequate zinc intake was found in 14.5 and 40% of infants at 2 and 4 months old, respectively. The prevalence of biochemical zinc and iron deficiency in infants were 76 and 11%, respectively. Iron endowment was significantly associated with serum ferritin at 4 months. The cumulative zinc intake was positively associated with weight gain and weight-for-length Z-score, but not length. This study provides quantitative data on zinc and iron intakes, and demonstrates the relative importance of nutrient storage versus intakes on biochemical status and growth of breastfed infants.

BACKGROUND: Infants' feeding practices in the first 6 months of life and their association with iron status and hematologic parameters has not been well studied. We aim to evaluate this association. METHODS: In a retrospective chart review, we identified 403 infants who received laboratory screening for anemia at 6-month visits. Infants were categorized into four groups according to feeding practices. Hematologic parameters and incidence of anemia, iron deficiency (ID), and iron deficiency anemia (IDA) were compared. RESULTS: In total, 105 infants were breastfed (BF), 78 were breastfed with iron supplementation starting at 4 months (BI), 109 were mixed-fed (breast milk and formula) with or without iron supplementation (MF), and 111 were formula-fed (FF). The BF group had the highest incidence of anemia (38.1%), ID (28.6%), and IDA (17.1%) when compared with the other groups (p < 0.001). In multivariate logistic regression, BI, MF, and FF infants had 90.4%, 97.5%, and 96.9% decreased risk of IDA, respectively, with BF infants as a reference group. CONCLUSION: The incidence of anemia, ID, and IDA at age 6 months was higher in BF than FF or MF infants. However, iron supplements in BF infants starting at 4 months significantly reduced their ID and IDA incidence.
ABSTRACT
BACKGROUND: Many international medical organizations recommend vitamin D supplementation for infants, especially exclusively breastfed infants. In Thailand, however, data regarding the vitamin D status in Thai infants are lacking. Such data would help to support physician decisions and guide medical practice. METHODS: Full-term, exclusively breastfed infants were randomized into two groups at 2 months of age to continue exclusive breastfeeding either without vitamin D supplementation (control group, n = 44) or with vitamin D3 supplementation at 400 IU/day (intervention group, n = 43) until 6 months of age. At 6 months, the serum vitamin D (25OHD) of the infants and their mothers, serum bone marker, and infants' growth parameters were compared between the two groups. RESULTS: The infants' serum 25OHD concentration was lower in the control group than intervention group (20.57 ± 12.66 vs. 46.01 ± 16.42 ng/mL, p < 0.01). More infants had vitamin D sufficiency (25OHD of > 20 ng/mL) in the intervention group than control group (93.0% vs. 43.2%, p < 0.01). There were no significant differences in the maternal 25OHD concentrations between the control and intervention groups (25.08 ± 7.75 vs. 23.75 ± 7.64 ng/mL, p = 0.42). Serum calcium, phosphorus, intact parathyroid hormone, alkaline phosphatase, and infants' growth parameters were comparable between the two groups. After adjustment for the confounding factors, 25OHD concentration in the intervention group was 25.66 ng/mL higher than the control group (95% confidence interval, 19.07-32.25; p < 0.001). Vitamin D supplement contributed to an 88.7% decrease in the prevalence of vitamin D insufficiency/deficiency (relative risk, 0.11; 95% confidence interval, 0.04-0.35; p < 0.01). CONCLUSIONS: Most full-term, exclusively breastfed Thai infants have serum vitamin D concentration below sufficiency level at 6 months of age. However, vitamin D supplementation (400 IU/day) improves their vitamin D status and prevents vitamin D deficiency. TRIAL REGISTRATION: The study was pre-registered in the Thai Clinical Trials Registry ( TCTR20190622001 ) on 22/06/2019.

Screening for anemia is recommended among infants aged 9 to 12 months. This study was conducted to determine the prevalence of anemia among 9-month-old infants at Well Child Clinic, and associated factors with anemia. Well Child record of all visits during January to December 2018 were reviewed. Hemoglobin (Hb) was determined by complete blood count (CBC) or point-of-care Hb (POC-Hb). Anemia was found in 99 from 145 infants (68.3%). The prevalence of anemia was 33.3% and 72.8% when tested by CBC and POC-Hb, respectively. Breastfed Infants had significantly lower mean Hb than formula-fed infants. The odd ratio [95% confident interval] of having anemia among infants who were fed with infant formula were 0.37 [0.14-0.94]; P = .038 when compared to breastfed infants. There was a high proportion of anemia among 9-month-old infants in Rama-WCC and breastfeeding was associated with anemia in infants. The use of POC-Hb may overestimate the prevalence of anemia.
ABSTRACT
BACKGROUND: Patients with thalassemia encounter increased consumption of zinc (Zn) and copper (Cu) from chronic hemolysis and increased excretion from iron chelation. Iron-enriched diet restriction may result in low Zn and Cu intakes. Recent data on Zn and Cu status among Thai pediatric patients with thalassemia are lacking. This study aimed to identify frequencies and determine risk factors of Zn and Cu deficiencies among patients with thalassemia. METHODS: Patients with transfusion-dependent thalassemia (TDT) receiving iron chelation ≥12 months and nonTDT (NTDT) aged 2-20 years were recruited. Serum Zn and Cu were measured. Dietary intakes were ascertained by interviews. RESULTS: A total of 209 patients (TDT = 126, NTDT = 83) were enrolled. Zn deficiency seemed to be associated with disease severity as median (IQR) Zn level of TDT was lower than that of NTDT [77 (69-85) vs. 80 (72-88) mcg/dL, p = 0.05], while higher frequency of Zn deficiency was identified in the former (24 % vs. 14 %). In TDT, Zn deficiency was associated with patients >10 years (OR 4.6; 95 %CI 1.1-6.4, p = 0.03), which likely resulted from combined low dietary Zn intake, prolonged exposures to hemolysis and iron chelators. Frequencies of Cu deficiency were similarly low in TDT and NTDT (8% and 7%) with comparable median (IQR) Cu levels of 103 (90-124) and 110 (92-132) mcg/dL, respectively (p = 0.13). Cu levels were inversely associated with age (r=-0.65 and r=-0.62 in TDT and NTDT, respectively; p < 0.001). CONCLUSION: Compared with younger patients, Zn and Cu deficiencies were more common among patients with thalassemia >10 years. Age was a major factor associated with both Zn and Cu deficiencies.

Zinc and iron deficiencies among infants aged under 6 months may be related with nutrient store at birth. This study aimed to investigate the association between zinc and iron stores at birth with maternal nutritional status and intakes during pregnancy. 117 pregnant women were enrolled at the end of second trimester and followed until delivery. Clinical data during pregnancy, including pre-pregnancy body mass index (BMI) and at parturition were collected from medical record. Zinc and iron intakes were estimated from a food frequency questionnaire. Serum zinc and ferritin were determined in maternal blood at enrollment and cord blood. Mean cord blood zinc and ferritin were 10.8 ± 2.6 µmol/L and 176 ± 75.6 µg/L, respectively. Cord blood zinc was associated with pre-pregnancy BMI (adj. ß 0.150; p = 0.023) and serum zinc (adj. ß 0.115; p = 0.023). Cord blood ferritin was associated with pre-pregnancy BMI (adj. ß -5.231; p = 0.009). Cord blood zinc and ferritin were significantly higher among those having vaginal delivery compared to cesarean delivery (adj. ß 1.376; p = 0.007 and 32.959; p = 0.028, respectively). Maternal nutritional status and mode of delivery were significantly associated with zinc and iron stores at birth. Nutrition during preconception and pregnancy should be ensured to build adequate stores of nutrients for infants.

BACKGROUND: Micronutrient intake and status in lactating women may impact micronutrient levels in milk. OBJECTIVES: This study aimed to determine the micronutrient intake and status in lactating women, and their association with micronutrient levels in human milk. METHODS: Lactating women were enrolled at 4-6 months postpartum. A 24h food recall was examined and nutrient intakes were analyzed using INMUCAL software. Human milk samples were collected to analyze calcium, copper, iron, and zinc levels. Plasma zinc and serum ferritin levels were determined. RESULTS: Thirty-four women participated; 19 were classified as full breastfeeding and 15 as partial breastfeeding. Mean levels of calcium, copper, iron, and zinc in human milk were 243, 0.2, 0.2, and 1.56 mg/L, respectively. The prevalence of zinc deficiency (plasma zinc < 10.7 µmol/L) was 11.8%. No lactating women had iron deficiency. Nutrient intakes were lower than the recommended amounts in 38%-70% of participants, and were not correlated with corresponding nutrient levels in human milk. Multiple linear regression showed significant association between zinc levels in human milk and plasma for lactating women with full breastfeeding (ß = 0.034, 95% confidence interval [0.003, 0.067], p = 0.040). CONCLUSIONS: Lactating women were at risk of micronutrient deficiency. There was an association between zinc levels in human milk and plasma of lactating women with full breastfeeding. As the nutritional status of lactating women influences the quality of human milk, we should encourage good nutrient intake for lactating women.

BACKGROUND: Zinc and iron deficiencies among breastfed infants during the first 6 months of life have been reported in previous studies. The amounts of zinc and iron intakes from breast milk are factors that contribute to the zinc and iron status of breastfed infants. OBJECTIVE: This study aims to quantitatively determine zinc and iron intakes by breastfed infants during the first 4 months of life and to investigate the factors that predict zinc and iron status in breastfed infants. METHODS: Pregnant women at 28 to 34 weeks of gestation were enrolled. Zinc and iron status during pregnancy was assessed. At delivery, cord blood was analyzed for zinc and iron levels. Participants and their babies were followed at 2 and 4 months postpartum. Maternal dietary intakes and anthropometric measurements were performed. The amount of breast milk intake was assessed using the deuterium oxide dose-to-mother technique. Breast milk samples were collected for determination of zinc and iron levels. The amount of zinc and iron consumed by infants was calculated. Zinc and iron status was determined in mothers and infants at 4 months postpartum. RESULTS: A total of 120 pregnant women were enrolled, and 80 mother-infant pairs completed the study (56 provided full breastfeeding, and 24 provided breast milk with infant formula). All data are being managed and cleaned. Statistical analysis will be done. CONCLUSIONS: This study will provide information on zinc and iron intakes in exclusively breastfed infants during the first 4 months of life and explore predictive factors and the possible association of zinc and iron intakes with infant growth and nutrient status.

ABSTRACT
Iodine deficiency in infants leads to delayed growth and development. Some studies have reported iodine deficiency among infants and lactating women. We assessed iodine status in infants and lactating women, as well as the iodine content in breast milk. A cross-sectional study enrolled mother-infant pairs (infants aged 4-6 months), who visited Well Child Clinic at Ramathibodi Hospital, Bangkok, Thailand. Infants were classified by feeding type as breastfed (BF), mixed breastfed and formula-fed (MF), and formula-fed (FF). Demographic and perinatal data were collected. The urinary iodine concentration (UIC) of infants and lactating women, and breast milk iodine concentration (BMIC) were analyzed. Seventy-one infants were enrolled. The median UIC of infants was 282 mcg/L. Breastfed infants had higher median UIC than formula-fed infants (553 vs. 192 mcg/L; p = 0.002). Forty-eight percent of infants had a UIC more than 300 mcg/L. The median UIC and BMIC of lactating women were 149 and 255 mcg/L, respectively. Among the BF group, the infant UIC was correlated with maternal UIC (rs = 0.857, p = 0.014). Multiple linear regression showed the BMIC to be associated with maternal UIC (ß = 4.03, 95% CI [1.34, 6.71]) and maternal weight (ß = 8.26, 95%CI [2.76, 13.77]). Iodine nutrition among our study population was adequate. The median UIC of infants and lactating mothers were 282 and 149 mcg/L, respectively. Breastfed infants had a significantly higher median UIC than formula-fed infants. The BMIC was associated with maternal UIC and maternal weight.

Breast milk provides adequate nutrients during the first 6 months of life. However, there are some reports of zinc deficiency in breastfed infants. This study was conducted to determine the prevalence of zinc deficiency in infants aged 4-6 months and the associated factors. Healthy infants aged 4-6 months and their mothers were enrolled. They were classified by feeding types as breastfed (BF), formula-fed (FF), and mixed groups (MF). Data collection included demographic data, perinatal data, given diets, and anthropometric measurement. Blood from infants and lactating mothers, and breast milk samples were collected to assess plasma and breast milk zinc concentrations. From 158 infants, the prevalence of zinc deficiency (plasma level below 10.7 mol/L) was 7.6%, and according to feeding groups 14.9%, 5.3%, and 2.9% in the BF, the FF, and the MF groups, respectively. Breastfed infants with zinc deficiency had significantly lower maternal zinc concentrations compared with those without zinc deficiency. There was a higher proportion of maternal zinc deficiency in zinc-deficient infants than those without zinc deficiency (66.7% vs 16.2%, p=0.02). There was a positive correlation between zinc concentrations in breast milk and plasma zinc concentrations of infants (r=0.62, p=0.01) and plasma zinc concentrations of lactating mothers (r=0.56, p=0.016). Using the regression analysis, infant zinc status was associated with maternal plasma zinc concentrations among breastfed infants. The results of this study suggest that breastfed infants aged 4-6 months may have a risk of zinc deficiency and that risk is associated with maternal zinc status and breast milk zinc concentrations.
