Determinants of concurrent wasting and stunting among children 6 to 23 mo in Indonesia.

OBJECTIVES: Concurrent wasting and stunting (WaSt) in a child is a health problem that leads to detrimental effects. However, to our knowledge, there is limited research regarding the prevalence and determinants of WaSt, including in Indonesia. The aim of this study was to analyze the prevalence and determinants of WaSt in children 6 to 23 mo of age. METHODS: This cross-sectional study was conducted with data sets from the Indonesia Nutritional Status Survey (INSS). Data was collected between January and December 2021. About 15 641 children, ages 23 mo, were included. A χ2 analysis examined the association between the dependent and independent variables. A multivariate test analyzed the risk for the independent variable to the dependent, seen through the adjusted odds ratio (aOR). RESULTS: The prevalence of WaSt was 2.4%. Higher odds for WaSt were seen in the following: • Boys: 2.15 times (95% confidence interval [CI], 1.72-2.68); • Children ages 12 to 23 mo 3.15 times (95% CI, 2.33-4.25); • Those with low birth weight 3.11 times (95% CI, 2.33-4.15) • Those with small birth size: 2 times (95% CI, 1.59-2.54) • Babies born from mothers >35 y of age: 1.5 times (95% CI, 1.19-1.89); • Children who experienced infection: 1.43 times (95% CI, 1.16-1.76); • Children not using the Integrated Health and Nutrition Services (Posyandu): 1.17 times (95% CI; 1.29-2.27); • Children from middle- income families:2.54 times higher odds (95% CI, 1.75-3.7); and • Children from rural areas: 1.37 times (95% CI, 1.1-1.71). CONCLUSION: WaSt is associated with multiple factors in Indonesia. Hence, policymakers need to address this problem comprehensively.

Sociocultural environmental factors and childhood stunting: qualitative studies - a protocol for the Shared Values theme of the UKRI GCRF Action Against Stunting Hub.

INTRODUCTION: Stunting is a significant and growing global problem that is resisting scientific attempts to understand it in terms of direct nutrition-related determinants. In recent years, research included more complex, indirect and multifactorial determinants and expanded to include multisectoral and lifestyle-related approaches. The United Kingdom Research Initiative Global Challenges Research Fund's (UKRI GCRF) Action Against Stunting Hub starts on the premise that dominant factors of stunting may vary between contexts and life phases of the child. Thus, the construction of a typology of clustered factors will be more useful to design effective programmes to alleviate it.The Shared Values theme seeks to build a bottom-up holistic picture of interlinked cultural contextual factors that might contribute to child stunting locally, by first eliciting shared values of the groups closest to the problem and then enquiring about details of their relevant daily activities and practices, to reveal links between the two. We define shared values as what groups consider 'valuable, worthwhile and meaningful' to them. METHODS AND ANALYSIS: We will recruit 12-25 local stakeholder groups in each site (in India, Indonesia and Senegal) involved in children's food and early learning environments, such as mothers, fathers, grandmothers, teachers, market vendors and health workers. The WeValue InSitu process will be used to assist them to collectively elicit, negotiate and self-articulate their own shared values through exploration of shared tacit knowledge. Focus group discussions held immediately subsequently will ask about daily activities relevant to the children's environment. These contain many examples of cultural contextual factors potentially influencing stunting locally, and intrinsically linked to shared values articulated in the previous session.

Effects of Cooking with Liquefied Petroleum Gas or Biomass on Stunting in Infants.

BACKGROUND: Household air pollution is associated with stunted growth in infants. Whether the replacement of biomass fuel (e.g., wood, dung, or agricultural crop waste) with liquefied petroleum gas (LPG) for cooking can reduce the risk of stunting is unknown. METHODS: We conducted a randomized trial involving 3200 pregnant women 18 to 34 years of age in four low- and middle-income countries. Women at 9 to less than 20 weeks' gestation were randomly assigned to use a free LPG cookstove with continuous free fuel delivery for 18 months (intervention group) or to continue using a biomass cookstove (control group). The length of each infant was measured at 12 months of age, and personal exposures to fine particulate matter (particles with an aerodynamic diameter of ≤2.5 µm) were monitored starting at pregnancy and continuing until the infants were 1 year of age. The primary outcome for which data are presented in the current report - stunting (defined as a length-for-age z score that was more than two standard deviations below the median of a growth standard) at 12 months of age - was one of four primary outcomes of the trial. Intention-to-treat analyses were performed to estimate the relative risk of stunting. RESULTS: Adherence to the intervention was high, and the intervention resulted in lower prenatal and postnatal 24-hour personal exposures to fine particulate matter than the control (mean prenatal exposure, 35.0 µg per cubic meter vs. 103.3 µg per cubic meter; mean postnatal exposure, 37.9 µg per cubic meter vs. 109.2 µg per cubic meter). Among 3061 live births, 1171 (76.2%) of the 1536 infants born to women in the intervention group and 1186 (77.8%) of the 1525 infants born to women in the control group had a valid length measurement at 12 months of age. Stunting occurred in 321 of the 1171 infants included in the analysis (27.4%) of the infants born to women in the intervention group and in 299 of the 1186 infants included in the analysis (25.2%) of those born to women in the control group (relative risk, 1.10; 98.75% confidence interval, 0.94 to 1.29; P = 0.12). CONCLUSIONS: An intervention strategy starting in pregnancy and aimed at mitigating household air pollution by replacing biomass fuel with LPG for cooking did not reduce the risk of stunting in infants.

Exploring Factors Associated with Stunting in 6-Month-Old Children: A Population-Based Cohort Study in Sulawesi, Indonesia.

Stunting in children under the age of two is a significant global concern, particularly in low- and middle-income countries like Indonesia. Intervention efforts often come too late as many of the underlying causal factors have already occurred earlier. While antenatal multiple micronutrient supplements (MMS) have demonstrated positive effects on pregnancy outcomes, their impact on infant growth in the first six months remains inadequately explored in epidemiological studies. This study aims to identify factors associated with stunting at six months in infants whose mothers received MMS. A population-based cohort study was conducted in four subdistricts of Banggai, Indonesia. Pregnant women were recruited in their third trimester and followed up until their children were six months of age. Validated questionnaires were employed to gather data on social determinants of health and diet, and standardised methods were utilised for anthropometric measurements. Stunting was determined based on the WHO child growth standards. The analysis comprised data from 152 mother-child pairs. The prevalence of stunting during early infancy (first two months) was 18.4%, which decreased to 15.8% in later infancy (at six months). Factors such as small-for-gestational-age (AOR = 11.29; 2.73-46.66), preterm birth (AOR = 6.33; 1.25-31.97), short birth length (AOR = 4.31; 1.11-16.78), maternal mid-upper arm circumference (MUAC) below 23.5 cm, and female infants (AOR = 3.27; 95%CI: 1.04-10.27) were associated with stunting at six months. This study highlights that stunting in the first six months is present at birth, with small-for-gestational-age (SGA) as a strong predictor. In addition, there was a trend to improved growth (-0.30 [-0.79 to 0.18]) in infants born to mothers who received MMS supplementation pre-pregnancy rather than during pregnancy, although it was not statistically significant.

Factors Affecting Village Apparatus, Integrated Service Post and Early Childhood Education in Stunting Prevention.

Background: The study aimed to identify the achievement of stunting prevention based on the contribution of the Village Apparatus, Integrated Health Services Post and Early Childhood Education. Moreover, it determined the effect of the personnel factors of each agency on the achievement of stunting prevention. Methods: A cross-sectional study was conducted on 175 respondents in Surakarta residences covering Klaten, Boyolali, Karanganyar, Surakarta, Sukoharjo, and Sragen districts from August to October 2021. The researcher conducted a line plot to describe the score of stunting prevention efforts through SINAR APD in planning, funding, implementation, and monitoring. Linear regression and One Way Anova were analyzed using SPSS to determine the effect of the personnel factors. Results: Personnel factors had a significant role in the achievement of funding for Stunting Prevention. The data of stunting showed knowledge (F=3.3; P<0.05), attitudes towards authoritative parenting (F=5.6; P<0.05), and attitudes towards permissive parenting (F=6.1; P<0.05). Conclusions: The main problem was the lack of achievement in the funding aspect. The researcher recommended further research to increase knowledge on stunting for village apparatus, Integrated Health Services Post and Early Childhood Education. Understanding good parenting patterns can change mindsets and attitudes to avoid applying parenting methods that are too authoritarian or permissive.

Prevalence of stunting and associated factors among neonates in Shebadino woreda, Sidama region South Ethiopia; a community-based cross-sectional study 2022.

INTRODUCTION: Stunting is a syndrome that begins at conception and leads to severe, irreversible physiological, physical and cognitive damage as an irreversible consequence of nutritional deficiencies and recurrent infections. Although multiple studies have been conducted in Ethiopia to show the magnitude of stunting and factors, all are concentrated on children aged between 6 to 59 months. Therefore, this study was done to determine the prevalence and associated factors of stunting at birth among new-borns. METHODS: A community-based cross-sectional study design was employed on 512 neonates in Shebadino Woreda, Sidama Region South Ethiopia 2022. A multistage sampling technique was employed. The data was collected door-to-door using pretested and structured questionnaires, through face-to-face interviews. The collected data were cleaned manually, coded, entered into Epidata version 4.6, and exported to SPSS version 26 software for analysis. Bi-variable analysis was conducted to assess the association of independent variables with the outcome variable. Variables with a p-value < 0.25 in bi-variable logistic regression were further analyzed using multivariable logistic regression. The odds ratio (OR) with 95% CI was used as a measure of association, and variables that had a p-value less than 0.05 in the multivariable logistic regression were considered as significantly associated variables. RESULT: The prevalence of stunting in this study was 27.5%: 95% CI 22.6 to 31.9. Factors such as residence (AOR = 4.1, 95% CI: 1.49, 11.25), ANC follow up (AOR = 2.66, 95% CI: 1.34, 5.27), started taking Amessa (AOR = 3.48, 95% CI: 1.27, 9.55) and Sex of the neonate (AOR = 2.15, 95% CI: 1.54, 5.23) were significantly associated with stunting at a p-value of < 0.05. CONCLUSION: About 27% of neonates were stunted, which implies, it require a quick public health measurement. New-born who were live in rural area and those who were started traditional medication (Amessa) were more stunted. Besides this, stunting was prevalently observed among a mother who had no ANC follow-up and male neonates. Thus, the regional health bureau and Shebedino woreda health office should increase awareness creation to bring behavioural change at community level to prevent traditional medication usage, ANC follow-up and giving priority for those who live in rural area.

Space-time dynamics regression models to assess variations of composite index for anthropometric failure across the administrative zones in Ethiopia.

BACKGROUND: A single anthropometric index such as stunting, wasting, or underweight does not show the holistic picture of under-five children's undernutrition status. To alleviate this problem, we adopted a multifaceted single index known as the composite index for anthropometric failure (CIAF). Using this undernutrition index, we investigated the disparities of Ethiopian under-five children's undernutrition status in space and time. METHODS: Data for analysis were extracted from the Ethiopian Demographic and Health Surveys (EDHSs). The space-time dynamics models were formulated to explore the effects of different covariates on undernutrition among children under five in 72 administrative zones in Ethiopia. RESULTS: The general nested spatial-temporal dynamic model with spatial and temporal lags autoregressive components was found to be the most adequate (AIC = -409.33, R2 = 96.01) model. According to the model results, the increase in the percentage of breastfeeding mothers in the zone decreases the CIAF rates of children in the zone. Similarly, the increase in the percentages of parental education, and mothers' nutritional status in the zones decreases the CIAF rate in the zone. On the hand, increased percentages of households with unimproved water access, unimproved sanitation facilities, deprivation of women's autonomy, unemployment of women, and lower wealth index contributed to the increased CIAF rate in the zone. CONCLUSION: The CIAF risk factors are spatially and temporally correlated across 72 administrative zones in Ethiopia. There exist geographical differences in CIAF among the zones, which are influenced by spatial neighborhoods of the zone and temporal lags within the zone. Hence these findings emphasize the need to take the spatial neighborhood and historical/temporal contexts into account when planning CIAF prevention.

Zinc Kinetics Correlate With Length-for-Age z Scores in Bangladeshi Infants.

OBJECTIVES: Stunting [length-for-age z score (LAZ) <-2] has multiple causes and is prevalent in areas with low dietary zinc (Zn) intake. Zinc kinetics from non-stunted infants were used in a published model for predicting linear growth; here, we directly measure zinc kinetics in stunted infants. METHODS: Zinc kinetics were determined in 9-month-old Bangladeshi infants (n = 10), who were non-wasted [weight-for-length z score (WLZ) > -2], ranging in LAZ from -2.9 to -0.43. Stable isotopes were administered 2 hours after a meal as oral ( 70 Zn) and intravenous ( 67 Zn) tracers. After isotope administration, blood was sampled within 5 hours and all urine and feces were collected for 24 hours. Urine was sampled twice-daily out to 9 days. Data were analyzed by compartmental modeling. Daily zinc intake was estimated by the model as the sum of zinc used for growth plus that lost via urine and feces. Zinc absorbed (the amount required to maintain steady state) was the sum of zinc used for growth plus urine and endogenous fecal excretions. RESULTS: The LAZ score correlated with serum zinc concentration ( R = 0.77, P = 0.001), urinary zinc excretion ( R = 0.66, P = 0.010), and fractional zinc absorption from calculated daily intake ( R = 0.58, P = 0.030). In stunted infants (n = 8), the amount of zinc absorbed did not increase with calculated zinc intake unlike published values for non-stunted infants. CONCLUSIONS: Zinc kinetics in Bangladeshi infants correlate with LAZ and show that malabsorption of supplemental sources of zinc may occur in stunted infants.

Gender differences in nutritional status and determinants among infants (6-11 m): a cross-sectional study in two regions in Ethiopia.

BACKGROUND: A limited number of studies suggest that boys may have a higher risk of stunting than girls in low-income countries. Little is known about the causes of these gender differences. The objective of the study was to assess gender differences in nutritional status and its determinants among infants in Ethiopia. METHODS: We analyzed data for 2036 children (6-11 months old) collected as the baseline for a multiple micronutrient powders effectiveness study in two regions of Ethiopia in March-April 2015. Child, mother, and household characteristics were investigated as determinants of stunting and wasting. Multiple logistic regression models were used separately for boys and girls to check for gender differences while adjusting for confounders. The study is registered at http://www.clinicaltrials.gov/ with the clinical trials identifier of NCT02479815. RESULTS: Stunting and wasting prevalence is significantly higher among boys compared to girls, 18.7 vs 10.7% and 7.9 vs 5.4%, respectively. Untimely initiation of breastfeeding, not-exclusive breastfeeding at the age of 6 months, region of residence, and low maternal education are significant predictors of stunting in boys. Untimely introduction to complementary food and low consumption of legumes/nuts are significant predictors of stunting in both boys and girls, and low egg consumption only in girls. Region of residence and age of the mother are significant determinants of wasting in both sexes. Analysis of interaction terms for stunting, however, shows no differences in predictors between boys and girls; only for untimely initiation of breastfeeding do the results for boys (OR 1.46; 95%CI 1.02,2.08) and girls (OR 0.88; 95%CI 0.55,1.41) tend to be different (p = 0.12). CONCLUSION: In Ethiopia, boys are more malnourished than girls. Exclusive breastfeeding and adequate dietary diversity of complementary feeding are important determinants of stunting in boys and girls. There are no clear gender interactions for the main determinants of stunting and wasting. These findings suggest that appropriate gender-sensitive guidance on optimum infant and young child feeding practices is needed.

Worldwide evidence about infant stunting from a public health perspective: A systematic review. / Evidencia mundial sobre el retraso del crecimiento infantil desde una perspectiva de salud pública: revisión sistemática

INTRODUCTION: According to the World Health Organization (WHO) global estimates for 2017, 9.6% of children under 5 years old are stunted. Worldwide evidence shows that actions for preventing stunting and catching-up growth are relevant if addressed by all the sectors involved. Therefore, there is a need to identify 'intersectoral actions' to address the risk of stunting during pregnancy and the first 2 years of life. OBJECTIVE: To identify and describe worldwide evidence for prevention, nutritional interventions, and 'intersectoral collaboration' efforts against stunting in infants. MATERIALS AND METHODS: We conducted a systematic review in 2019 (PROSPERO CRD42019134431). The search included PubMed, OVID, and Web of Science, as well as WHO and the Food and Agriculture Organization of the United Nations (FAO) official documents and expert recommendations. RESULTS: We selected 231 studies: 86.1% described prevention-related factors, 30.7%, nutritional interventions, and 52.8% intersectoral collaboration efforts; 36.4% of the studies were conducted in multiple regions; 61% of the studies described the importance of interventions during pregnancy, 71.9% from birth up to 6 months old, and 84.8% from 6 months up to 2 years old. The most frequent variables described were antenatal care, nutritional counseling for the mother and the newborn, and counseling on micronutrient supplementation. CONCLUSIONS: Evidence-based understanding of actions geared towards monitoring the risk of stunting-associated factors from pregnancy up to 2 years old is critical.

Introducción. Según estimaciones mundiales de la Organización Mundial de la Salud (OMS) para el 2017, el 9,6 % de los niños menores de cinco años padecen retraso del crecimiento. La evidencia mundial ha demostrado que las acciones para prevenir el retardo del crecimiento o para tratarlo adquieren relevancia si las abordan todos los sectores involucrados. Por lo tanto, es necesario determinar las acciones intersectoriales para atender el riesgo de retraso del crecimiento durante el embarazo y los dos primeros años de vida. Objetivo. Rastrear y describir la evidencia mundial para la prevención, las intervenciones nutricionales y los esfuerzos de colaboración intersectorial contra el retraso del crecimiento en los lactantes. Materiales y métodos: Se hizo una revisión sistemática en el 2019 (PROSPERO CRD42019134431). La búsqueda incluyó PubMed, OVID y Web of Science, así como documentos oficiales de la OMS y la Organización para la Agricultura y la Alimentación de Naciones Unidas (FAO) y recomendaciones de expertos. Resultados. Se seleccionó un total de 231 estudios: 86,1 % describían factores relacionados con la prevención, 30,7 %, intervenciones nutricionales, y 52,8 %, esfuerzos de colaboración intersectorial; 36,4 % de ellos se llevaron a cabo en múltiples regiones. Del total, el 61 % de los estudios se enfocaba en la importancia de las intervenciones durante el embarazo, el 71,9 % desde el nacimiento hasta los seis meses y el 84,8 % desde los seis meses hasta los dos años. Las variables descritas con mayor frecuencia fueron la atención prenatal, el asesoramiento nutricional para la madre y el recién nacido, y el asesoramiento sobre la suplementación con micronutrientes. Conclusiones. La comprensión basada en la evidencia de las acciones orientadas a monitorear el riesgo de factores asociados al retraso del crecimiento desde el embarazo hasta los dos años, es fundamental.

Factors Associated with Stunted Growth in Children Under Five Years in Antananarivo, Madagascar and Bangui, Central African Republic.

OBJECTIVES: With a fourth of all under-five children affected, stunting remains one of the biggest health challenges worldwide. Even though the main underlying factors are known, the exact pathways to stunting varying in affected regions, and interventions thus need to be tailored to the local contexts. This study aimed assessing and comparing factors associated with stunting in two understudied sub-Saharan urban contexts with some of the highest stunting prevalence globally: Bangui, Central African Republic (~ 36%) and Antananarivo, Madagascar (42%). METHODS: We performed a case-control study on 175 + 194 stunted and 237 + 230 non-stunted control children aged 2-5 years and matched for age, gender and district of residency. Factors associated with stunting were identified using a standardized, paper questionnaire delivered by trained interviewers. Statistical analysis was done using logistic regression modelling. RESULTS: In both sites, formal maternal education lowered the risk of being stunted and restricted access to soap, suffering of anaemia and low birth weight were associated with higher risk of stunting. Short maternal stature, household head different from parents, diarrhoea and coughing were associated with an increased risk and continuing breastfeeding was associated with a lower risk of stunting in Antananarivo. Previous severe undernutrition and dermatitis/ fungal skin infections were associated with higher and changes in diet during pregnancy with lower risk of stunting in Bangui. CONCLUSIONS: Our results suggest maternal education, antenatal care, iron supplementation and simple WASH interventions such as using soap and infection control as general and breastfeeding (Antananarivo) or better nutrition (Bangui) as area-specified interventions.

Maternal Preconception Body Size and Early Childhood Growth during Prenatal and Postnatal Periods Are Positively Associated with Child-Attained Body Size at Age 6-7 Years: Results from a Follow-up of the PRECONCEPT Trial.

BACKGROUND: Growth faltering is associated with adverse consequences during childhood and later life. However, questions remain on the relative importance of preconception maternal nutritional status (PMNS) and child growth during the first 1000 d of life. OBJECTIVES: We examined associations between PMNS, gestational weight gain (GWG), and child growth during the first 1000 d with attained body size at age 6-7 y. METHODS: We used data from a follow-up of a double-blinded randomized controlled trial of preconception micronutrient supplementation in Vietnam (n = 5011 women). The outcomes included offspring height-for-age z score (HAZ), BMI-for-age z score (BMIZ), and prevalence of stunting and overweight/obese at age 6-7 y (n = 1579). We used multivariable linear and Poisson regression models to evaluate the relative contributions of PMNS (height and BMI), GWG, and conditional growth in 4 periods: fetal, 0-6 mo, 6-12 mo, and 12-24 mo. RESULTS: PMNS was positively associated with child-attained size at 6-7 y. For each 1-SD higher maternal height and BMI, offspring had 0.28-SD and 0.13-SD higher HAZ at 6-7 y, respectively. Higher maternal BMI and GWG were associated with larger child BMIZ (ß: 0.29 and 0.10, respectively). Faster linear growth, especially from 6 to 24 mo, had the strongest association with child HAZ at 6-7 y (ß: 0.39-0.42), whereas conditional weight measures in all periods were similarly associated with HAZ (ß: 0.10-0.15). For BMIZ at 6-7 y, the magnitude of association was larger and increased with child age for conditional weight gain (ß: 0.21-0.41) but smaller for conditional length gain. Faster growth in the first 2 y was associated with reduced risk of stunting and thinness but increased risk of overweight/obese at 6-7 y. CONCLUSIONS: Interventions aimed at improving child growth while minimizing the risk of overweight during the school age years should target both women of reproductive age prior to conception through delivery and their offspring during the first 1000 d. The trial was registered at clinicaltrials.gov as NCT01665378.

Shwachman-diamond syndrome: A case report.

RATIONALE: The aim of this study was to analyze the genetic abnormalities and clinical manifestations of Shwachman-Diamond syndrome (SDS). PATIENT CONCERNS: A Chinese infant with elevated transaminase and a novel mutation at of sbdsc.258 +2T>C and c.184a>Tc.292G>A. DIAGNOSES: The female patient was 5 months' old at onset, with elevated transaminase as the first manifestation accompanied by restricted growth and development and oily stool. After sequencing the blood samples from patients and their parents, the heterozygous mutations of sbdsc.258 +2T>C and c.184a>T were detected. INTERVENTIONS: After admission, the patient was provided compound glycyrrhizin, Newtide formula milk supplemented with probiotics, fat-soluble vitamins, oral medication to adjust the spleen and stomach, and other symptomatic treatments. OUTCOMES: The stool traits improved, and the levels of liver function transaminases decreased compared with before. LESSONS: SDS is a rare disease with a variety of clinical manifestations. Pancreatic exocrine dysfunction, blood system manifestations, and bone abnormalities are common clinical manifestations, and genetic testing is helpful for diagnosis.

Nutritional Status Among School-Age Children of Bangladeshi Tea Garden Workers.

BACKGROUND: While considerable progress has been made in reducing undernutrition in Bangladesh, regional disparities are known to exist, and certain population subgroups may lag behind. OBJECTIVE: To characterize nutritional status among school-age children in a historically marginalized population of Bangladesh. METHODS: We conducted a cross-sectional assessment of children attending 14 nongovernmental organization-operated schools serving the tea estate population in Kulaura Upazila, Sylhet Division. We randomly selected 168 children from a population of 418 whose parents attended school-organized Parent-Teacher Association meetings. Parents provided consent and data on household food consumption in the past week, foods consumed by children in the past 24 hours, and household food insecurity. We drew venous blood from assenting children for the analysis of hemoglobin and plasma retinol, C-reactive protein, and α1-acid glycoprotein. Children were classified as stunted, underweight, or thin based on comparisons with the World Health Organization standards for height-for-age, weight-for-age, or body mass index-for-age, respectively. RESULTS: Food insecurity was highly prevalent, with ∼85% of households affected. Roughly half of children had low dietary diversity. Prevalence estimates for stunting, underweight, and thinness were 32%, 50%, and 49%, respectively. Approximately 60% of children had a hemoglobin concentration <11 g/dL. The mean (±SD) plasma retinol concentration was 0.79 µmol/L (±0.23 µmol/L), with 34% deficient using a 0.70 µmol/L cutoff. CONCLUSIONS: A heightened focus on tracking progress in underserved populations and appropriately targeted programming will be critical as Bangladesh seeks to accelerate progress toward global development goals for nutrition.

Clinical impact of hypothalamic-pituitary disorders after conformal radiation therapy for pediatric low-grade glioma or ependymoma.

BACKGROUND: To determine the impact of hypothalamic-pituitary (HP) disorders on health outcomes in children and adolescents who received conformal radiation therapy (RT) for central nervous system tumors. PROCEDURE: Cohort study including 355 patients (age ≤25 years at diagnosis) treated with high-dose (50.4-59.4 Gy) RT using photons for low-grade glioma or ependymoma. Patients (median age, 6.4 years at RT) received systematic endocrine follow-up (median duration, 10.1 years; range, 0.1-19.6). Associations between HP disorders and adverse health outcomes were determined by multivariable analysis. RESULTS: Prevalence was 37.2% for growth hormone deficiency (GHD), 17.7% for gonadotropin deficiency (LH/FSHD), 14.9% for thyroid-stimulating hormone deficiency (TSHD), 10.3% for adrenocorticotropic hormone deficiency (ACTHD), and 12.6% for central precocious puberty (CPP). Hypothalamus mean dose ≥ 36 Gy was associated with higher odds of any deficiency. GHD was associated with short stature (OR 2.77; 95% CI 1.34-5.70), low bone mineral density (OR 3.47; 95% CI 1.16-10.40), and TSHD with dyslipidemia (OR 5.54; 95% CI 1.66-18.52). Patients with ACTHD and CPP had lower intelligence quotient scores, and memory scores were impaired in patients with GHD (P = 0.02). Treatment of GHD was not associated with increased risk for tumor recurrence, secondary tumors, or mortality. CONCLUSIONS: HP disorders occur frequently in patients receiving high-dose RT and are related to physical and neurocognitive well-being. Future studies are needed to assess whether further optimization of endocrine management yields better health outcomes.

Prevalence and factors associated with stunting among school children in Egypt.

BACKGROUND: Stunting adversely affects children's health and development. Few studies on the prevalence of stunting and factors associated with stunting have been done in Upper Egypt. AIMS: This study aimed to determine the prevalence of and factors associated with stunting in schoolchildren in Sohag, Egypt. METHODS: This was a cross-sectional study conducted in 2017 in Sohag governorate. Two public schools were randomly selected (one urban, one rural) and all children in these schools aged 4-12 years whose parents consented were included in the study. Parents were interviewed to collect data on child and family characteristics. The children were examined for vitamin deficiency, anaemia and parasitic infection, and body mass index was calculated. Multivariate logistic regression analysis was done to determine factors significantly associated with stunting; odds ratios (ORs) and 95% confidence intervals (CIs) are given. RESULTS: A total of 1786 children were included (response rate 69%), of whom 329 (18.4%) were stunted (-2 z-score and below). Factors significantly associated with stunting were: parasite infestation (OR = 1.8, 95% CI: 1.3-2.5), anaemia (OR = 1.7, 95% CI: 1.3-2.7), low body mass index (OR = 1.2, 95% CI: 1.1-1.3), frequent gastroenteritis (OR = 1.1, 95% CI: 1.06-1.2), first-cousin consanguinity of parents (OR = 1.3, 95% CI: 1.2-1.6) and familial short stature (OR = 1.5, 95% CI: 1.2-2.1). CONCLUSION: Screening and treatment of parasitic infestation, provision of iron/multivitamin supplementation and education on healthy nutrition should be part of school health programmes to prevent stunting in schoolchildren in Sohag.

Zinc deficiency in low- and middle-income countries: prevalence and approaches for mitigation.

This review addresses the prevalence of zinc deficiency in Low- and Middle-income Countries (LMICs) and assesses the available strategies for its alleviation. The paucity of national-level data on the zinc deficiency in LMICs is partially a result of the lack of a reliable biomarker. Zinc deficiency appears to be a public health problem in almost all the LMICs, irrespective of the recommended indicators (plasma zinc concentration, dietary zinc adequacy and stunting prevalence) used. Based on plasma/serum zinc concentration (PZC), which is the most appropriate indicator at present, the prevalence of zinc deficiency in LMICs is of concern. Among the 25 countries for which national PZC data were available, 23 had a zinc deficiency prevalence of >20% for at least one physiological group. Zinc supplementation is largely restricted as an adjunct therapy for diarrhoea management in children, and the best platform and the most effective way of preventive zinc supplementation delivery remains to be established. Impact assessment for current zinc fortification programmes in LMICs and the effectiveness of zinc supplementation as part of a multi-micronutrient powder is to be determined. Dietary diversification, though promising for LMICs, is in the nascent stages of development at present. Inclusion of meat and animal products can be an important way of improving zinc status. Programmatic experience with the promotion of home processing techniques to increase absorbable zinc in the diet is lacking. Conventional biofortification techniques are gaining recognition in LMICs; however, transgenic biofortification as a strategy remains controversial.

Environmental exposure to metal mixtures and linear growth in healthy Ugandan children.

BACKGROUND: Stunting is an indicator of poor linear growth in children and is an important public health problem in many countries. Both nutritional deficits and toxic exposures can contribute to lower height-for-age Z-score (HAZ) and stunting (HAZ < -2). OBJECTIVES: In a community-based cross-sectional sample of 97 healthy children ages 6-59 months in Kampala, Uganda, we examined whether exposure to Pb, As, Cd, Se, or Zn were associated with HAZ individually or as a mixture. METHODS: Blood samples were analyzed for a mixture of metals, which represent both toxins and essential nutrients. The association between HAZ and metal exposure was tested using multivariable linear regression and Weighted Quantile Sum (WQS) regression, which uses mixtures of correlated exposures as a predictor. RESULTS: There were 22 stunted children in the sample, mean HAZ was -0.74 (SD = 1.84). Linear regression showed that Pb (ß = -0.80, p = 0.021) and Se (ß = 1.92, p = 0.005) were significantly associated with HAZ. The WQS models separated toxic elements with a presumed negative effect on HAZ (Pb, As, Cd) from essential nutrients with presumed positive effect on HAZ (Se and Zn). The toxic mixture was significantly associated with lower HAZ (ß = -0.47, p = 0.03), with 62% of the effect from Pb. The nutrient WQS index did not reach statistical significance (ß = -0.47, p = 0.16). DISCUSSION: Higher blood lead and lower blood selenium level were both associated with lower HAZ. The significant associations by linear regression were reinforced by the WQS models, although not all associations reached statistical significance. These findings suggest that healthy children in this neighborhood of Kampala, Uganda, who have a high burden of toxic exposures, may experience detrimental health effects associated with these exposures in an environment where exposure sources are not well characterized.

Whole-blood PUFA and associations with markers of nutritional and health status in acutely malnourished children in Cambodia.

OBJECTIVE: To measure fatty acid composition, particularly whole-blood PUFA content, in acutely malnourished children and identify associations with markers of nutritional and health status. DESIGN: PUFA were assessed in dried blood spots obtained from a cross-sectional study. Nutritional and health status were assessed by anthropometry, haemoglobinopathies, inflammation and blood counts. SETTING: Cambodia. PARTICIPANTS: The study was conducted with 174 children aged 0·5-18 years with acute malnutrition. RESULTS: Among total fatty acids (FA), the relative percentage of total PUFA was 20 % FA, with 14 % of the children having very low PUFA (mead acid (MA):arachidonic acid (AA) >0·02, n-6 docosapentaenoic acid:DHA >0·2 and total n-6:n-3 PUFA >10·5). Wasting was not associated with any PUFA. Stunting and low height were consistently positively associated with total PUFA and positively with n-6 PUFA. Height was positively associated with n-3 long-chain PUFA (LCPUFA). The presence of haemoglobinopathies or inflammation was positively associated with MA:AA, but not total PUFA. Elevated blood platelet counts were positively correlated with linoleic acid and appeared to be influenced by anaemia (P = 0·010) and inflammation (P = 0·002). Monocyte counts were high during inflammation (P = 0·052) and correlated positively with n-6 LCPUFA and n-3 LCPUFA. CONCLUSIONS: Children with acute malnutrition or stunting had low PUFA, while elevated platelets and monocytes were associated with high PUFA. In acutely malnourished children, inflammation could lead to elevated blood cell counts resulting in increased whole-blood PUFA which does not reflect dietary intake or nutritional status.

Poor Dietary Diversity Is Associated with Stunting among Children 6-23 Months in Area of Mergangsan Public Health Center, Yogyakarta.

The period of pregnancy and the first two years of children are called the golden period so that the adequacy intake of macro and micronutrients must be fulfilled. Stunting is a chronic undernutrition condition as a result of inadequate quality and quantity of complementary foods with or without infectious diseases. Quality and quantity of complementary foods can affect linear growth. To analyzed the association between dietary diversity and stunting among children aged 6-23 mo in the area of Mergangsan public health center, Yogyakarta. Method: Study was an analytic observational study with a cross-sectional design. The population was children aged 6-23 mo from 60 integrated health service centers in the area of Mergangsan public health center with a total population of 343 children. The sample size was 135 children. Samples were selected using simple random sampling. Data were analyzed using univariate (descriptive), bivariate (chi-square test), and multivariate analysis (multiple logistic regression). The result of bivariate analysis showed that there was a significant association between dietary diversity of complementary foods (p=0.012; RP=2.87; CI: 1.23-6.68) and father's height (p=0.03; RP=2.58; CI: 1.06-6.30) with stunting. The result of the multivariate analysis showed that there was a significant association between dietary diversity of complementary foods and stunting while there was no association between the father's height and stunting. Poor dietary diversity of complementary foods was a risk factor of stunting among children aged 6-23 mo.
