Malnutrition prevalence in hospitalized pediatric patients: A comparison of national and World Health Organization growth standards.

The aim of the study was to investigate the frequency of malnutrition in hospitalized children and compare national growth standards with World Health Organization (WHO) standards. After obtaining height, weight, and mid-upper arm circumference values for 250 children aged 1 month to 5 years, nutrition status was assessed separately according to Neyzi and WHO standards. Weight-for-age z score (WAZ), weight-for-height z score (WHZ), height-for-age z score (HAZ), and mid-upper arm circumference z score (MUACz) were calculated based on age. Patients with WHZ < -2 were considered to have acute malnutrition, while those with HAZ < -2 were considered to have chronic malnutrition per WHO's definition. According to the WHO and Neyzi standards, the z scores were as follows: WAZ (-0.53 ± 1.54/-0.61 ± 1.52), HAZ (-0.42 ± 1.61/-0.45 ± 1.38), WHZ (-0.33 ± 1.26/none), MUACz (-0.58 ± 1.31/none). The difference between WAZ scores for the two standards was highly significant (P = 0.0001), whereas the difference between HAZ scores didn't reach statistical significance (P = 0.052). In our study when evaluated according to WHO standards, the prevalence of acute and chronic malnutrition was 9.6% and 13.6%, respectively. The prevalence of chronic malnutrition in those aged <2 years was higher than in the 2-5 years age group (16.8% and 4.5%, respectively; P = 0.012). There were highly significant differences in the assessment of malnutrition between the WHO and national Neyzi according to WAZ standards, contradicting the claim that WHO curves can be universally applicable. The high rates of acute and chronic malnutrition in our study indicate that malnutrition remains a significant nutrition problem in our country.

Growth and gut comfort of healthy term infants exclusively fed with a partially hydrolysed protein-based infant formula: a randomized controlled double-blind trial.

This study aimed to investigate growth and gut comfort of healthy infants fed with a partially hydrolysed cow's milk protein-based infant formula (pHF) compared to a standard intact cow's milk protein-based formula (IPF). A double-blind, multi-center, randomized, controlled trial was performed. Healthy full-term, exclusively formula-fed infants (n = 345), aged ≤28 days were allocated to consume either a pHF (n = 173) or an IPF (n = 172) until the age of 17 weeks. The primary outcome was equivalence of weight gain (g/d) until the age of 17 weeks. The secondary outcomes were equivalence of other growth parameters, i.e., infants' weight, length, head circumference, body mass index (BMI) and anthropometric Z-scores, while tertiary outcomes were gut comfort, formula intake, and adverse events (AEs). Overall, 288 infants completed the study (pHF group: 138, IPF group: 150). No differences were observed between the two groups in weight gain (g/d) during the three-months intervention [p = 0.915 for the Per Protocol (PP) population]. The 90% CI was [-1.252 to 1.100] being within the pre-defined equivalence margin of ±3.0 g/d. Similar findings were observed in the Full Analysis Set (FAS) and the sensitivity analysis. Regarding the secondary outcomes, no differences over the intervention period were shown between the two groups in both the PP and FAS analysis sets. Average Z-scores were in the normal range based on World Health Organization (WHO) growth standards for both groups at all time points in both analysis sets. Stool consistency, amount, and colour were different in the two groups. No differences were observed in gut comfort, stool frequency, and formula intake, between the two groups. In total 14 AEs and 22 serious adverse events (SAEs) were reported of which 15 (12%) and 1 (5%) were considered as (possibly) related to the study product, respectively. The study demonstrates that the consumption of pHF results in adequate infant growth, equivalent to that of infants consuming IPF. Furthermore, the overall gut comfort was comparable between the two groups. Therefore, it can be concluded that the pHF is safe for and well tolerated by healthy infants. https://clinicaltrials.gov/study/NCT05757323?id=NCT05757323&rank=1, identifier (NCT05757323).

Growth patterns by birth size of preterm children born at 24-29 gestational weeks for the first 3 years.

Concerns are prevalent about preterm infant long-term growth regarding plotting low on growth charts at discharge, stunting, underweight, high body fat and subsequent cardiometabolic morbidities. To examine (a) longitudinal growth patterns of extremely and very preterm infants to 3 years corrected age (CA) (outcome), categorised by their birthweight for gestational age: small, appropriate and large for gestational age (SGA, AGA and LGA, respectively) (exposure); and (b) the ability of growth faltering (<-2 z-scores) to predict suboptimal cognitive scores at 3 years CA. Post-discharge head, length, weight and weight-4-length growth patterns of the PreM Growth cohort study infants born <30 weeks and < 1500 g, who had dietitian and multi-disciplinary support before and after discharge, were plotted against the World Health Organization growth standard. Infants with brain injuries, necrotising enterocolitis and bronchopulmonary dysplasia were excluded. Of the included 405 infants, the proportions of infants with anthropometric measures > - 2 z-scores improved with age. The highest proportions <-2 z-scores for length (24.2%) and weight (24.0%) were at 36 gestational weeks. The proportion with small heads waslow by 0 months CA (1.8%). By 3 years CA, only a few children plotted lower than -2 z-scores for length, weight-4-length and weight (<6%). After zero months CA, high weight-4-length and body mass index > + 2 z-scores were rare (2.1% at 3 years CA). Those born SGA had higher proportions with shorter heights (16.7% vs. 5.2%) and lower weights (27.8% vs. 3.5%) at 3 years CA compared to those born AGA. The ability of growth faltering to predict cognitive scores was limited (AUROC 0.42, 95% CI 0.39, 0.45 to 0.52, 95% CI 0.41, 0.63). Although children born <30 weeks gestation without major neonatal morbidities plot low on growth charts at 36 weeks CA most catch up to growth chart curves by 3 years CA.

Analysis and prediction of nutritional outcome of patients with pediatric inflammatory bowel disease from Bahrain

BackgroundInflammatory bowel disease (IBD) is a chronic gastrointestinal disease that causes anorexia, malabsorption, and increased energy requirements. Childhood IBD can significantly impact nutritional status and future health.ObjectiveThis study aimed to analyze the nutritional status of patients with pediatric IBD at presentation and during follow-up and to identify predictors of nutritional outcome.MethodsThis retrospective cohort study reviewed the medical records of children diagnosed with IBD in the Pediatric Department, Salmaniya Medical Complex, Bahrain, 1984 − 2023. Demographic data, clinical characteristics, and anthropometric data were collected. World Health Organization growth standards were used to interpret nutritional status.ResultsOf the 165 patients, 99 (60%) had anthropometric data at presentation, and 130 (78.8%) had follow-up data. Most patients were males (64.6%) and had Crohn’s disease (CD) (56.2%), while 43.8% had ulcerative colitis (UC). The median age at presentation was 10.9 years and the mean follow-up duration was 12.6 years. At presentation, 53.5% of the patients were malnourished, that decreased to 46.9% on follow-up. Thinness was reduced from 27.3% at presentation to 12.1% at follow-up (p = 0.003). There was an increased tendency to normal weight on follow-up (59.6%) compared to time of presentation (46.5%), p = 0.035. Overweightness showed a non-significant increase from 26.3% at presentation to 28.3% at follow-up (p = 0.791). Children with IBD were more likely to become obese when they grow up to adulthood (2.3% versus 20.5%, respectively, p < 0.001). Weight-for-age, and height-for-age at presentation were higher among CD compared to UC, but body mass index (BMI) at follow-up was higher among UC patients (p < 0.05). Thinness at follow up was associated with very early-onset disease (p = 0.02), lower weight and BMI at presentation (p < 0.001 each), younger age at follow-up (p = 0.002), pediatric age group (p = 0.023), lower hematocrit (p = 0.017), and higher C-reactive protein (p = 0.007). Overweight at follow up was associated with increased weight and BMI at presentation (p < 0.001 each), longer disease duration (p = 0.005), older age (p = 0.002), and azathioprine intake (p = 0.026). Considering follow-up duration, univariate analysis exhibited that Bahraini nationality, post-diagnosis disease duration, age at follow-up, occurrence of diarrhea, height, and BMI at presentation were factors that decreased liability to abnormal nutritional status, while CD, history of weight loss, perianal disease, and skin rash, and intake of prednisolone expressed increased liability of abnormal nutritional status (p < 0.05).ConclusionPediatric IBD is associated with a high incidence of malnutrition. Thinness is more prominent at presentation, while overweight is higher on follow-up. Multiple risk factors aggravating abnormal nutritional status were highlighted. Accordingly, nutritional counseling should be prioritized in a multidisciplinary approach.

Unsafe child feces disposal and childhood wasting among under five children in Myanmar

Background: Wasting is a major public health problem among under five children in developing countries, including Myanmar. The distribution of wasting and its associated factors are not well known in Myanmar. Objectives: This study aimed to examine the wasting prevalence and identify the association between child feces disposal and wasting among under-five children in Myanmar. Methods: A cross-sectional study was conducted on 1,207 under five children in Myanmar from September to December 2022. This study employed a multistage random sampling method with structured questionnaires and anthropometric measures. The World Health Organization's (WHO) definition and growth standards were used to determine the wasting. Multivariable logistic regression was performed to identify the association. An adjusted odds ratio with a 95% confidence interval and a p-value &lt;0.05 was used to define statistical significance. Results: The prevalence of childhood wasting among under five children in Myanmar was 11.10% (95% CI: 9.45 to 13.00). This study revealed that children from unsafe child feces disposing families were 94 % more likely to be wasted (AOR=1.94, 95% CI: 1.22 to 3.09; p-value 0.005). Other covariates to childhood wasting were water shortage (AOR=2.17, 95% CI: 1.13 to 4.16; p-value 0.02), less than four handwashing steps of mother (AOR=3.20, 95% CI: 1.93 to 5.32; p-value &lt;0.001), located in hilly region (AOR=2.27, 95% CI: 1.53 to 3.37; p-value &lt;0.001), boys (AOR=2.80, 95% CI: 1.86 to 4.23; p-value &lt;0.001), birth interval less than 3 years (AOR=1.84, 95% CI: 1.10 to 3.11; p-value 0.02), and eating more than 4 times per day (AOR=3.19, 95% CI: 1.93 to 5.27; p-value &lt;0.001). Conclusion: This study showed a high prevalence of wasting among under five children in Myanmar. Improving the safe child feces disposal practices of mothers would be a critical intervention to reduce under five children's wasting.

Significant differences in the length and weight measurements of Jordanian infants compared to the World Health Organization 2006 growth standards.

In 2006, the World Health Organization (WHO) introduced new growth standards based on data derived globally from optimally nourished breastfed infants. The aim of this study was to assess the effects of implementing WHO growth standards on the growth patterns of Jordanian infants. In addition, it was to ascertain the necessity of establishing country-specific growth standards and charts tailored to Jordanian infants. The data of 102,846 infants (50.1% boys, 49.9% girls) aged 0-24 months, from 115 primary healthcare centers across the country were retrieved from a National E-health Program. Weight and length measurements were analyzed, and age- and sex-specific z-scores were calculated relative to the WHO growth standards. Data was analyzed using SPSS version 26. Mann-Whitney U test was performed to determine significant differences between the measurements for boys and girls in terms of age, length, and weight. Jordanian infants exhibited significantly shorter length-for-age measurements than WHO standards with mean z-scores of -0.56 and -0.38, for boys and girls, respectively. Weight-for-age measurements showed a good fit and were comparable to the WHO growth standards for boys (mean z score = -0.05) and girls (mean z score = 0.04). Notably, Jordanian infants displayed higher weight-for-length measurements, with mean z-scores of 0.51 for boys and 0.47 for girls. The availability of Jordanian-specific growth standards will improve the accuracy of assessing infant growth and enhance the monitoring and evaluation of their health and development.

Sibship Composition and BMI Z-Score Among Saudi Preschoolers: A Cross-Sectional Study.

Background and objective The association between sibship composition and child body mass index (BMI) has not been investigated in any Arab/Middle Eastern populations. In light of this, this study aimed to examine the association of the number of siblings, number of older siblings, and number of younger siblings with child BMI z-score (BMIz) among preschoolers in the Kingdom of Saudi Arabia (KSA). Methods A total of 209 mothers and their children were recruited from preschools in Jeddah, KSA. Mothers reported their responses to the study questionnaire via telephone. Child anthropometry was objectively measured; BMIz was calculated based on age- and sex-specific World Health Organization (WHO) growth standards and reference data. We used hierarchical multiple linear regression to examine the association between sibship composition variables and child BMIz, independent of the effect of potential confounders, and to evaluate changes in model fit. Results The number of siblings was negatively associated with child BMIz [b = -0.18, 95% confidence interval (CI) = -0.35, -0.06, p<0.01, adjusted R2= 0.16]. There was a negative association between the number of older siblings and child BMIz (b = -0.23, 95% CI = -0.38, -0.11, p<0.01, adjusted R2= 0.21) as well as between the number of older sisters and child BMIz (b = -0.18, 95% CI = -0.52, -0.09, p<0.01, adjusted R2= 0.19). However, there were no significant associations between the number of older brothers or the number of younger siblings and child BMIz. Conclusions Based on our findings, sibship composition was found to be associated with BMIz among a sample of preschoolers in KSA. More research is needed to further establish this association and to understand the underlying mechanism of the association of the greater number of older siblings and older sisters with lower BMIz.

Comparison of WHO 2006 Growth Standards and Synthetic Indian References in Assessing Growth in Normal Children and Children with Growth-Related Disorders.

A good screening tool, such as a growth chart, should distinguish between children with normal growth and those with perturbed growth. Suitability of synthetic Indian growth references for diagnosing growth-related disorders for under-five children has not been evaluated. To assess the validity of World Health Organization (WHO) 2006 standards vs synthetic Indian references (2019) (by comparing weight, height, body mass index (BMI), standard deviation scores (SDS) and the composite index of anthropometric failure (CIAF)) in differentiating normal children and children with growth-related disorders. Records of 2188 children (0-60 months) attending a tertiary centre paediatric outpatient department (OPD) were retrospectively studied; 1854 children were healthy and 334 were diagnosed with growth-related disorders as per the European Society for Paediatric Endocrinology (ESPE) classification. The anthropometric parameters converted to Z-scores for weight-for-age (WAZ), height-for-age (HAZ), BMI-for-age (BAZ) and a CIAF were computed using WHO and synthetic charts; Student's t-test was used for assessing differences and Youden's index for validity. Disease status of children and anthropometric failure on WAZ, HAZ, BAZ and CIAF on both WHO and synthetic charts had a significant association (P-value <0.05). WAZ, HAZ on both charts and CIAF on synthetic chart had a fair to moderate agreement (Kappa statistics) with disease status as per diagnosis (P-value <0.05). The sensitivity and negative predictive value for all anthropometric parameters were higher for synthetic charts. Indian charts were more sensitive for diagnosing growth-related disorders from birth to 60 months of age when compared to WHO growth standards.

Prevalence, Incidence, and Reversal Pattern of Childhood Stunting From Birth to Age 2 Years in Ethiopia

Although there has been a reduction in stunting (low-height-for-age and low-length-for-age), a proxy of malnutrition, the prevalence of malnutrition in Ethiopia is still high. Child growth patterns and estimates of stunting are needed to increase awareness and resources to improve the potential for recovery. To estimate the prevalence, incidence, and reversal of stunting among children aged 0 to 24 months. This population-based cohort study of the Birhan Maternal and Child Health cohort in North Shewa Zone, Amhara, Ethiopia, was conducted between December 2018 and November 2020. Eligible participants included children aged 0 to 24 months who were enrolled during the study period and had their length measured at least once. Data analysis occurred from Month Year to Month Year. The primary outcome of this study was stunting, defined as length-for-age z score (LAZ) at least 2 SDs below the mean. Z scores were also used to determine the prevalence, incidence, and reversal of stunting at each key time point. Growth velocity was determined in centimeters per month between key time points and compared with global World Health Organization (WHO) standards for the same time periods. Heterogeneity was addressed by excluding outliers in sensitivity analyses using modeled growth trajectories for each child. A total of 4354 children were enrolled, out of which 3674 (84.4%; 1786 [48.7%] female) had their length measured at least once and were included in this study. The median population-level length was consistently below WHO growth standards from birth to 2 years of age. The observed prevalence of stunting was highest by 2 years of age at 57.4% (95% CI, 54.8%-9 60.0%). Incidence of stunting increased over time and reached 51.0% (95% CI, 45.3%-56.6%) between ages 12 and 24 months. Reversal was 63.5% (95% CI, 54.8%-71.4%) by age 6 months and 45.2% (95% CI, 36.0%-54.8%) by age 2 years. Growth velocity point estimate differences were slowest compared with WHO standards during the neonatal period (-1.4 cm/month for girls and -1.6 cm/month for boys). There was substantial heterogeneity in anthropometric measurements. The evidence from this cohort study highlights a chronically malnourished population with much of the burden associated with growth faltering during the neonatal periods as well as after 6 months of age. To end all forms of malnutrition, growth faltering in populations such as that in young children in Amhara, Ethiopia, needs to be addressed.

Levels of stunting associated factors among under-five children in Ethiopia: A multi-level ordinal logistic regression analysis.

Stunting is a major public health problem affecting more than one-third of under five year's old children in Ethiopia. It has short and long (irreversible) consequences, including stunted growth, never reaching physical and cognitive potential, struggles in school, and increased morbidity and mortality due to infections. Though stunting is the leading cause of child mortality in Ethiopia, evidence is scarce on the prevalence and predictors of stunting among under-five years old children in Ethiopia. Therefore, this study aimed to estimate the prevalence and predictors of stunting severity among under-5 children in Ethiopia. This study was based on 2019 Mini-Ethiopian Demographic and Health Survey (EDHS) data. A weighted total sample of 4972 under-five years old children was included in the study. Height measurement was collected for each child. Anthropometric indicator, height-for-age was determined for children using World Health Organization growth standards (Z-scores for Height-for-Age (HAZ)) to asses stunting level. Given the ordinal nature of stunting and the hierarchical nature of EDHS data, a multilevel ordinal logistic regression model was applied. Brant test was used to check the proportional odds assumption, which was satisfied (P-value ≥0.05). Moreover, deviance was used for model comparison. For the multivariable analysis, variables with a p-value ≤0.2 in the bivariable analysis were considered. The Adjusted Odds Ratio (AOR) with 95% Confidence Interval (CI) was reported as associated factor to the severity levels of stunting in the multivariable multilevel proportional odds model. The overall prevalence of stunting among under-5 children in Ethiopia was 35.7% [95% CI: 34.4%, 37.1%]. Of these, 12.1% were severely stunted, and 24.9% were moderately stunted. Being male [AOR = 0.83, 95% CI: 0.74, 0.93], children aged 6-23 months [AOR = 2.38, 95% CI: 1.84, 3.07], ≥ 24 months [AOR = 4.15, 95% CI: 3.26, 5.28], children whose maternal age 15-24 years [AOR = 0.73, 95% CI: 0.58, 0.92], children from the poorest, poorer, middle, and richer household wealth were [AOR = 1.84, 95% CI: 1.32, 2.57], [AOR = 1.66, 95% CI: 1.20, 2.31], [AOR = 1.78, 95% CI: 1.29, 2.44], and [AOR = 1.62, 95% CI: 1.20, 2.17], children whose maternal educational status of no formal education and primary education had [AOR = 1.90, 95% CI: 1.28, 2.82], [AOR = 1.78, 95% CI: 1.22, 2.60], Tigray [AOR = 2.95, 95% CI: 1.78, 4.86], Afar [AOR = 1.85, 95% CI: 1.11, 3.10], Amhara [AOR = 1.90, 95% CI: 1.14, 3.14] and Harari [AOR = 1.97, 95% CI: 1.20, 3.25]regions, low community maternal education [AOR = 0.76, 95% CI: 0.62, 0.92] were significantly associated with stunting severity levelling. Stunting among children under five years of old in Ethiopia remains a major public health issue. Improving access to maternal education is related to appropriate child feeding practices and health, particularly in younger and uneducated mothers. Strengthening the family's wealth status is also recommended to reduce stunting. In addition, it is better to support strategies of preconception care for mothers during pregnancy to reduce stunting in the long term.

Malnutrition among Children under Age Five in Panama: Results of the ENSPA 2019.

Background: Malnutrition has important short- and long-term consequences in children under age five. Malnutrition encompasses undernutrition, overnutrition, and the coexistence of both of them, known as the double burden of malnutrition (DBM). Objective: The aim of this study was to estimate the prevalence of undernutrition, overnutrition, and the DBM among these children at the national level and by living area in Panama. Methods: Data from the National Health Survey of Panama (ENSPA, Spanish acronym), a population-based, cross-sectional study carried out in 2019 were used. Stunting, wasting, overweight, and obesity were defined according to the cut-off points of the World Health Organization Growth Standards. Undernutrition was defined as being stunted only, wasted only or both; overnutrition was defined as being overweight only or obese only; and the DBM was defined as the co-occurence of stunting and overweight/obesity in the same child. Prevalence and general characteristics at the national level and by living area were weighted. Findings: The prevalence of undernutrition was 15.3% (95% confidence interval (CI) 13.4-17.3) at the national level and 36.6% (CI: 30.1-43.5) in indigenous areas. The prevalence of overnutrition was 10.2% (8.2-12.6) at the national level and 11.9% (CI: 8.5-16.3), 8.4% (CI: 6.5-10.7) and 8.7% (CI: 5.2-14.3) in urban, rural and indigenous areas, respectively. The DBM prevalence was 1.4% (CI: 1.0-2.1) at the national level and 2.7% (CI: 1.4-5.1) in indigenous areas. Conclusions: Undernutrition is still the most prevalent malnutrition condition in our country. Panama has the highest prevalence of overnutrition in Central America. The highest prevalence of undernutrition and DBM was found among children living in indigenous areas.

The role of adipokines and ghrelin in interactions and clinical implications in childhood obesity.

Childhood obesity is a growing global health concern, especially prevalent in the Arabian Peninsula, and is known to contribute to metabolic syndrome and insulin resistance. This study aimed to investigate the interplay between adipokines (leptin and adiponectin), ghrelin, and insulin homeostasis in childhood obesity. A case-control study was conducted in Babylon involving 120 children/adolescents (7-17 years). The participants were divided into two groups: 60 obese and 60 healthy controls. Anthropometric and biochemical measures were examined, applying World Health Organization (WHO) growth standards to categorize weight status. Data on blood lipids, glucose, adipokines, and ghrelin were collected in Babylon (Merjan Medical City), ensuring accuracy and providing insights into pediatric obesity's metabolic and hormonal status. Clinical, anthropometric, and laboratory attributes of children were evaluated, with classification as normal-weight or obese based on BMI/Z-score and Waist Circumference. The obese group exhibited elevated triglycerides and insulin levels, as well as reduced adiponectin levels (P ≤ 0.001). Leptin levels showed a positive correlation with BMI/Z-score (r = 0.352, P = 0.006). A diagnostic model demonstrated the significant diagnostic capacity of leptin (AUC > 99%) and its importance in predicting childhood obesity. Each unit increase in leptin elevated the probability of obesity by a factor of 1.197 (95% CI: 1.0507-1.3632, P = 0.0068). The study revealed significant differences in clinical, biochemical, and biological markers of obesity between the research groups and the control group. Leptin emerged as a significant predictor of obesity, demonstrating high diagnostic accuracy. The complex interactions among these adipokines underscore the necessity for comprehensive obesity management strategies.

A comparison of mid-upper arm circumference and weight-for-height Z score of world health organization growth standards in detecting moderate and severe acute malnutrition in children aged 6-60 months

Background: World health organization (WHO) had defined severe acute malnutrition (SAM) and moderate acute malnutrition (MAM) by weight for height Z score (WHZ) and mid upper arm circumference (MUAC) criteria. Several studies indicate discrepancies in the prevalence of malnutrition on using either WHZ or MUAC. The prevalence of SAM was nearly same when using either criterion and only 40% children showed overlapping by using both the criteria. Present study was taken to identify the overlapping of cases by applying both the WHO criteria in children aged 6-60 months. It also identifies the optimal screening cut off values of MUAC if used as a sole criterion. Method: It was a hospital based descriptive cross-sectional study done on 640 cases who were assessed for MAM /SAM by using anthropometric WHO criteria. Results: From 67 SAM cases who were identified by WHZ, only17 cases had SAM on using MUAC too. The sensitivity of MUAC was 25.4% and specificity of 92.0%. From 94 MAM cases, 19 cases showed overlapping by using both the WHO criteria. At MUAC of &lt;13.5 cm, the sensitivity increased to 86.6% for SAM and 81.6% for MAM cases at the cost of decreased specificity which was at around 36% for both the types of malnutrition. Conclusions: The number of malnourished cases, identified by using either of WHO criteria were nearly same but both these criteria detect different subgroups of malnourished children in most cases. A MUAC of &lt;13.5 cm may be used as a sole-criteria in the community by the health workers to detect acute malnutrition.

Stunting and Associated Factors among Children Under Five Years in Yemen during the Conflict Period

It remains a significant public health problem in many low and middle-income countries, particularly in Yemen, related to nutritional deficiencies during the most critical periods of growth and development in early childhood. The purpose of this study was to determine the predictors of stunting and the associated factors among Yemeni children under 5 years of age. This study was conducted using a cross-sectional design among 434 mothers and their children aged 6-59 months. Data were collected through face-to-face interview using the structured questionnaire that consists of 28 items. Anthropometric indicator, height-for-age was determined using the current World Health Organization (WHO) growth standards. An analysis of the data was conducted using a multivariable logistic regression model. Statistical significance was determined by the Adjusted Odds Ratio (AOR) and 95% Confidence Interval (CI) from the multivariable analysis. The prevalence of stunting among children under the age of five was 46.1%. According to the multivariable analysis, stunting is statistically associated with children aged 13-24 months (AOR 2.04), 25-36 months (AOR 2.27), 37-48 months (AOR 2.38), secondary education of the father (AOR 0.31), household size of five members (AOR 0.66), and flushed or poured toilets (AOR 1.91). In Yemen, family-specific factors are the primary contributors to stunted development in children. There is a need to emphasize interventions related to food, nutrition, and overall hygiene to reduce malnutrition in the studied region and the country as a whole.

Changes of anthropometric indicators of lithuanian first-graders in 2008–2019 according to International Obesity Task Force (IOTF) and World Health Organization (WHO) definitions

IntroductionThe monitoring of children’s growth plays a crucial role in assessing their growth patterns and indicating their weight status. Overweight and obesity, determined by cut-offs of body mass index (BMI), are most commonly associated with unhealthy nutrition, non-communicable diseases, and other health disorders. The World Health Organization (WHO) initiated the WHO European Childhood Obesity Surveillance Initiative (COSI) to measure routinely trends in children’s anthropometric changes, which allow intercountry comparisons within the European Region. Lithuania joined the COSI initiative. Our study aims to evaluate and compare underweight, normal and elevated weight (overweight and obesity) changes of Lithuanian first-graders during eleven years period.MethodsThis study was composed according to the COSI study protocol, and it compares the five rounds of anthropometric measurements of Lithuanian first-graders (7-8-year-old) from 2008 to 2019. The main analysed variables were weight and height; calculated BMI, weight-for-age (W/A), height-for-age (H/A) and body mass index-for-age (BMI/A) z-scores. Changes of the indicators were evaluated according to the International Obesity Task Force (IOTF) cut-offs and WHO child growth standards, grouped by 4 estimates: underweight (thinness), normal weight, overweight and obesity. All comparisons were performed between age groups, gender and COSI round year.ResultsThe mean values for weight, height, W/A and H/A Z-scores were significantly higher for both age and gender groups when comparing later COSI round years (2016 or 2019) to earlier years (2008–2013, in some cases 2016 is included in this range). Time trends of the WHO growth standards and IOTF cut-offs indicate significant decrease among 7-year-old overweight group for boys and girls. Also, a significant decrease was indicated among boys aged 8 years in the overweight group according to the WHO definitions. The only significant increase in trend were expressed in girl’s group with obesity aged 8 years according to IOTF cut-offs.ConclusionThe prevalence of overweight and obesity of first-grade children in Lithuania indicates positive changes, that is the proportion of children with elevated body weight decreased, during eleven-year period. However, it is important to continue the monitoring of children’s growth tendencies.

Impact of anthropometry training and feasibility of 3D imaging on anthropometry data quality among children under five years in a postmortem setting.

The Child Health and Mortality Prevention Surveillance Network (CHAMPS) identifies causes of under-5 mortality in high mortality countries. To address challenges in postmortem nutritional assessment, we evaluated the impact of anthropometry training and the feasibility of 3D imaging on data quality within the CHAMPS Kenya site. Staff were trained using World Health Organization (WHO)-recommended manual anthropometry equipment and novel 3D imaging methods to collect postmortem measurements. Following training, 76 deceased children were measured in duplicate and were compared to measurements of 75 pre-training deceased children. Outcomes included measures of data quality (standard deviations of anthropometric indices and digit preference scores (DPS)), precision (absolute and relative technical errors of measurement, TEMs or rTEMs), and accuracy (Bland-Altman plots). WHO growth standards were used to produce anthropometric indices. Post-training surveys and in-depth interviews collected qualitative feedback on measurer experience with performing manual anthropometry and ease of using 3D imaging software. Manual anthropometry data quality improved after training, as indicated by DPS. Standard deviations of anthropometric indices exceeded limits for high data quality when using the WHO growth standards. Reliability of measurements post-training was high as indicated by rTEMs below 1.5%. 3D imaging was highly correlated with manual measurements; however, on average 3D scans overestimated length and head circumference by 1.61 cm and 2.27 cm, respectively. Site staff preferred manual anthropometry to 3D imaging, as the imaging technology required adequate lighting and additional considerations when performing the measurements. Manual anthropometry was feasible and reliable postmortem in the presence of rigor mortis. 3D imaging may be an accurate alternative to manual anthropometry, but technology adjustments are needed to ensure accuracy and usability.

Evaluating national guidelines for monitoring early growth using routinely collected data in Bergen, Norway.

The overarching aim of this study was to evaluate the Norwegian guidelines for growth monitoring using routinely collected data from healthy children up to five years of age. We analysed criteria for both status (size for age) and change (centile crossing) in growth. Longitudinal data were obtained from the electronic health record (EHR) at the well-baby clinic for 2130 children included in the Bergen growth study 1 (BGS1). Measurements of length, weight, weight-for-length, body mass index (BMI) and head circumference were converted to z-scores and compared with the World Health Organization (WHO) growth standards and the national growth reference. Using the WHO growth standard, the proportion of children above +2SD was generally higher than the expected 2.3% for all traits at birth and for length at all ages. Crossing percentile channels was common during the first two years of life, particularly for length/height. By the age of five years, 37.9% of the children had been identified for follow-up regarding length/height, 33% for head circumference and 13.6% for high weight-for-length/BMI. The proportion of children beyond the normal limits of the charts is higher than expected, and a surprisingly large number of children were identified for rules concerning length or growth in head circumference. This suggests the need for a revision of the current guidelines for growth monitoring in Norway.

Relationships between dental fluorosis and fluoride concentrations in bottled water and groundwater in low-income children in Mexico.

The aim of the current study was to investigate associations between dental fluorosis in children living in low socioeconomic areas in Mexico, and fluoride concentrations in tap water, fluoride concentrations and in bottled water, and body mass index (BMI). A cross-sectional study involving 585 schoolchildren aged 8-12 years was conducted in communities in a southern state of Mexico with >0.7 parts per million (ppm) fluoride in the groundwater. The Thylstrup and Fejerskov index (TFI) was used to evaluate dental fluorosis, and the World Health Organization growth standards were used to calculate age-adjusted and sex-adjusted BMI Z-scores. A BMI Z-score ≤ -1 SD was used as the cut-off point for thinness, and multiple logistic regression models for dental fluorosis (TFI ≥ 4) were constructed. The mean fluoride concentration in tap water was 1.39 ppm (SD 0.66), and the mean fluoride concentration in bottled water was 0.32 ppm (SD 0.23). Eighty-four children (14.39%) had a BMI Z-score ≤ -1 SD. More than half (56.1%) of the children presented with dental fluorosis in TFI categories ≥ 4. Children living in areas with higher fluoride concentrations in the tap water [odds ratio (OR) 1.57, p = 0.002] and bottled water (OR 3.03, p < .001) were more likely to have dental fluorosis in the severe categories (TFI ≥ 4). BMI Z-score was associated with the probability of dental fluorosis (TFI ≥ 4; OR 2.11, p < 0.001), and the effect size was 29.3%. A low BMI Z-score was associated with a higher prevalence of dental fluorosis in the severe category. Awareness of the fluoride concentrations in bottled water may help prevent dental fluorosis, particularly in children exposed to several high fluoride content sources. Children with a low BMI may be more vulnerable to dental fluorosis.

Family economic trajectories and body mass index in Indonesia: Evidence from the Indonesian Family Life Surveys 2 to 5

Indonesia faces the double burdens of childhood obesity and malnutrition. A family's socioeconomic status has been suggested to be one of the most influential factors contributing to childhood nutritional problems. This study aimed to: 1) identify the distinct trajectories of family economics; and 2) assess whether a family's economic trajectory influences children’s body mass index (BMI). We analyzed trajectory patterns of family economic levels from 1997 to 2015 among 846 children aged under 3 years in 1997 using data from Indonesian Family Life Surveys. Trajectory patterns were identified with Group-Based Trajectory Modeling using the traj plug-in in STATA software. The BMI was classified according to 2007 World Health Organization growth standards. Adjusted relative risk ratios (aRRRs) of family economic level trajectories and children’s BMI were calculated using multinomial logistic regressions. We identified three distinct trajectories of family economic level: stable poorest, stable middle, and increasing richest. In the total sample, there were no significant relationships between a family's income trajectory and children’s BMI in the adjusted models. A significant relationship existed for male children, but not for female children, of compared to the poorest family trajectory group, male children in the increasing richest trajectory group were more likely to be overweight/obese (aRRR 6.1, 95% confidence interval: 1.22–30.62) after adjusting for age and BMI. The present results highlight the importance of early interventions to minimize the potential adverse impacts of excessive BMI later in adulthood.

Reliability, acceptability, validity and responsiveness of the CHU9D and PedsQL in the measurement of quality of life in children and adolescents with overweight and obesity

BackgroundThe Paediatric Quality of life Inventory (PedsQLTM) Generic Core Scales and the Child Health Utilities 9 Dimensions (CHU9D) are two paediatric health-related quality of life (HRQoL) measures commonly used in overweight and obesity research. However, no studies have comprehensively established the psychometric properties of these instruments in the context of paediatric overweight and obesity. The aim of this study was to assess the reliability, acceptability, validity and responsiveness of the PedsQL and the CHU9D in the measurement of HRQoL among children and adolescents living with overweight and obesity.Subjects/MethodsSubjects were 6544 child participants of the Longitudinal Study of Australian Children, with up to 3 repeated measures of PedsQL and CHU9D and aged between 10 and 17 years. Weight and height were measured objectively by trained operators, and weight status determined using World Health Organisation growth standards. We examined reliability, acceptability, known group and convergent validity and responsiveness, using recognised methods.ResultsBoth PedsQL and CHU9D demonstrated good internal consistency reliability, and high acceptability. Neither instrument showed strong convergent validity, but PedsQL appears to be superior to the CHU9D in known groups validity and responsiveness. Compared with healthy weight, mean (95%CI) differences in PedsQL scores for children with obesity were: boys −5.6 (−6.2, −4.4); girls −6.7 (−8.1, −5.4) and differences in CHU9D utility were: boys −0.02 (−0.034, −0.006); girls −0.035 (−0.054, −0.015). Differences in scores for overweight compared with healthy weight were: PedsQL boys −2.2 (−3.0, −1.4) and girls −1.3 (−2.0, −0.6) and CHU9D boys: no significant difference; girls −0.014 (−0.026, −0.003).ConclusionPedsQL and CHU9D overall demonstrated good psychometric properties, supporting their use in measuring HRQoL in paediatric overweight and obesity. CHU9D had poorer responsiveness and did not discriminate between overweight and healthy weight in boys, which may limit its use in economic evaluation.
