Bioavailability of Australian pre-schooler iron intakes at specific eating occasions is low.

PURPOSE: Poor bioavailability may contribute to iron deficiency among children in high-resource countries, but iron bioavailability of Australian pre-schooler diets is unknown. This study aimed to estimate the bioavailability of Australian pre-schooler iron intakes across the day and by eating occasions to identify optimal timing for intervention, by using five previously developed algorithms, and to estimate the proportion of children with intakes of absorbable iron below the requirements. METHODS: Dietary data of children aged 2 to < 6 y (n = 812) from the 2011-12 National Nutrition and Physical Activity Survey were collected via two 24-h recalls. Usual food and nutrient intakes were estimated via Multiple Source Method. Phytate, polyphenol, and heme iron values were sourced from international databases or the literature. Five previously published algorithms were applied to observed dietary data to estimate iron bioavailability and calculate the prevalence of children with intakes of absorbable iron below requirements. RESULTS: Pre-schooler daily iron bioavailability was low (2.7-10.5%) and corresponded to intakes of 0.18-0.75 mg/d of absorbable iron. The proportion of children with inadequate intakes of absorbable iron ranged between 32 and 98%. For all eating occasions, dinner offered iron of the greatest bioavailability (4.2-16.4%), while iron consumed at breakfast was of the lowest bioavailability (1.2-5.6%). CONCLUSION: Future strategies are required to improve intakes of bioavailable iron for pre-schoolers to prevent the risk of deficiency. These strategies could include the encouragement of concomitant consumption of enhancers of iron absorption with iron-rich sources, particularly at breakfast.

Promoting healthy sleep in Chinese kindergarteners through a family-based intervention: protocol of the "Healthy Sleep" randomised controlled trial.

BACKGROUND: Sleep is instrumental for growth and development in children, making it critical to establish healthy sleep habits from the earliest years of life. Many kindergarteners (3-6 years) in China have inadequate and poor sleep, necessitating targeted interventions. This research protocol details the "Healthy Sleep" intervention that was designed to promote healthy sleep among kindergarteners in China. METHODS: The "Healthy Sleep" intervention will be family-based and will support parents as change agents. The development of the intervention is based on evidence regarding correlates of sleep in young children and guided by Bandura's social cognitive theory. A 12-month randomised controlled trial will be conducted to examine the efficacy of the intervention for promoting healthy sleep in Chinese kindergarteners and the intervention's effects on child development outcomes. A targeted sample of 160 kindergarteners and their parents will be recruited through social media. The intervention group (n = 80) will receive monthly webinars for one year that include multiple intervention components - including educational training, goal setting and planning, as well as follow-up support sessions. The control group (n = 80) will receive videos of the recorded educational sessions after the study end. For primary outcomes, child sleep behaviours will be examined using the Child Sleep Health Questionnaire. For secondary outcomes, communication, fine motor, gross motor, personal-social, and problem-solving development will be examined using the Ages and Stages Questionnaire; executive functions will be examined using the Head, Toes, Knees, and Shoulders Revised tasks. Potential intervention mediators and covariates will be measured using a parental questionnaire. Mixed models will be conducted. DISCUSSION: This intervention targets sleep behaviours among kindergarteners in China. It has the potential to inform programs to support parents in helping their child establish healthy sleep habits from the earliest years of life. The study will provide high-quality experimental evidence on sleep behaviours in relation to development outcomes in kindergarteners. This evidence will inform family-based strategies to optimise early childhood development and inform national and international updates of the sleep recommendations for young children. TRIAL REGISTRATION: The trial was registered prospectively at Chinese Clinical Trial Registry (ID: ChiCTR2300072105) on 2 June 2023.

Iron Nutrition of Pre-Schoolers in High-Income Countries: A Review.

Pre-schoolers are vulnerable to iron deficiency, which, in high-resource countries, is mainly caused by suboptimal or poorly absorbable iron intakes. This review examines the prevalence of inadequate iron intakes and status, and the non-dietary factors associated with these, among children aged between 2 and 5 years within high-income countries. It then considers the quality of the pre-schooler diet in terms of dietary factors, dietary patterns, and iron intakes. Additionally, it discusses the assessment of iron bioavailability and examines the various methods used to estimate the amount of absorbable iron in pre-schooler diets. Knowledge of the adequacy of iron intakes and bioavailability of iron intakes, and dietary patterns associated with iron intakes can facilitate the design and implementation of effectively targeted community-based intervention studies to improve iron intakes and iron bioavailability to minimise the risk of iron deficiency.

Correlates of screen time in the early years (0-5 years): A systematic review.

The majority of young children engage in high levels of screen time. To inform future interventions, knowledge on correlates of screen time is important. This review expands on previous work by focusing on the entire early childhood range, and including a broad focus regarding types of correlates and screens. A literature search (PubMed, Embase, PsycINFO, SPORTDiscus) was performed from 2000 up to October 2021. Included studies (cross-sectional and prospective) examined associations between a potential correlate and screen time (duration or frequency) in typically developing, apparently healthy children aged 0-5 years. Methodological quality was assessed by two independent researchers. Fifty-two of 6,614 studies were included. Two studies had high methodological quality. We found moderate evidence for a positive association between an electronic device in the bedroom, parental screen time, having a TV on at home, descriptive norms and screen time, and a negative association between sleep duration, household features, high value on physical activity, monitoring screen time, being in childcare, parental self-efficacy and screen time. We found no evidence for an association for child sex, body mass index, physical activity, temperament, number of siblings, being a first-born, neighborhood-related factors, socio-economic indicators, and parental marital status, physical activity, weight status, depression, wellbeing, sex, age and positive outcome expectations. The evidence for other investigated correlates was inconsistent or insufficient. Despite the evidence for moderate associations, we were unable to draw strong conclusions. More high-quality research is needed to identify correlates of screen time in early childhood.

Asia-Pacific consensus statement on integrated 24-hour activity guidelines for the early years.

Background: Early childhood is a vital period for development and growth. Promoting beneficial lifestyle behaviours in early childhood can help optimise children's health, development and learning, shape their behaviours in adulthood and offer the best protection against future non-communicable diseases (NCDs). In the Asia-Pacific region, NCDs are significant causes of healthcare burden and mortality. Furthermore, there is also a high prevalence of adverse metabolic risk factors and unhealthy lifestyle behaviours among these children. Method: Representatives from 19 Asia-Pacific nations and/or jurisdictions developed a consensus statement on integrated 24-hour activity guidelines for the early years using the GRADE-ADOLOPMENT framework. Findings: These guidelines apply to all infants, toddlers and pre-schoolers below 5 years of age. The guidelines aim to provide a holistic and practical approach to lifestyle activities by framing physical activity, sedentary behaviour and sleep within a 24-hour period. Dietary patterns were included as they play an integral role in metabolic health and energy balance. Interpretation: Aligned with the World Health Organization's Global Action Plan for the Prevention and Control of NCDs through health promotion interventions in early life, through cultivating healthy lifestyle behaviours in the children's early years, we aim to provide children with the best start in life and reduce the burden of future NCDs in the Asia-Pacific region. Funding: Funded by Integrated platform for research in advancing metabolic health outcomes of women and children.

Frequency and distribution of dietary energy, vegetable, fruit and discretionary food intakes in 18-month-old Australian children.

Dietary behaviours in early childhood are understudied despite links with later health. Assessing the distribution of key food groups across the day could identify opportunities for improvements. This study aimed to describe the 24-hourly distribution of dietary intakes and frequency of eating occasions for weekdays and weekend days among children aged 18 months and assess associations of eating frequency with vegetable, fruit and discretionary intakes and zBMI. Using two parent-reported 24-h recalls of child dietary intakes from the Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program, mean frequency of daily eating occasions and hourly intake distributions were calculated for vegetables, fruits, discretionary foods, and total foods and energy-containing beverages on weekdays (n 428) and weekend days (n 376). Multivariable regression analyses assessed associations between frequency of eating occasions, total intake of food groups and zBMI. Overall, children had 7·8 ± 1·8 (mean ± sd) eating occasions/d on weekdays, where 1·5 ± 0·8 contained vegetables, 2·2 ± 1·1 contained fruit and 2·5 ± 1·5 contained discretionary foods. Weekend day intakes were similar. Energy intakes were highest at dinner time. Intakes of total foods, fruits and discretionary foods were spread across the day (06.00-22.00). Vegetable consumption was mainly about 18.00 with minimal intake at other times. Eating frequency was associated with amount of food consumed but not consistently with zBMI. These 18-month-old children ate frequently throughout the day, with little distinction between weekdays and weekend days. Most eating occasions lacked vegetables, and frequency of discretionary foods was higher than of vegetables. Promoting vegetable consumption at occasions other than dinner could improve vegetable intake.

The reliability and validity of the isixhosa version of the euroqol toddler and infant populations (EQ-TIPS) health related quality of life instrument.

Background: Considering the high burden of disease in young children measurement of Health-Related Quality of Life is needed to evaluate the burden of morbidity. This study aims to report on the validity and reliability of the isiXhosa EuroQol Toddler and Infant Populations (EQ-TIPS) measure for South Africa. Methods: A sample of 181 caregivers of children 0-36 months were recruited from a hospital in-patient (inpt) and outpatient (outpt) facility and crèches. The EQ-TIPS, Ages and Stages Questionnaire (ASQ), Faces, Leg, Activity, Cry, Consolability (FLACC) and dietary information were administered at baseline. EQ-TIPS was administered one week later in crèche children for test-retest reliability. Results: Known groups showed significant differences for pain (X2=37.21, p<0.001), and EQ-TIPS level sum score (KWH=25.9, p<0.001) between health groups. The Visual Analogue Scale was unable to discriminate general health between groups (KW-H=3.92, p=0.141). Concurrent validity was weak to moderate and significant for all dimensions hypothesised to correlate. There was significant fair to moderate test-retest reliability for EQ-TIPS dimensions of movement, play, pain and eating. Conclusion: The isiXhosa EQ-TIPS is valid and reliable for very young children in South Africa and we suggest that it be included in the assessment of children with health conditions within this context.

Mealtime TV Use Is Associated with Higher Discretionary Food Intakes in Young Australian Children: A Two-Year Prospective Study.

BACKGROUND: Mealtime television use has been cross-sectionally associated with suboptimal diets in children. This study aimed to assess the two-year prospective association between baseline mealtime television use and subsequent diets in young children, and identify socioeconomic differences. METHODS: Parents reported their child's television use at meals, and fruit, vegetable, and discretionary food intakes. Multivariable linear and logistic regression analyses assessed the association between baseline mealtime television use and follow-up diet outcomes. Differences were assessed by socioeconomic position. RESULTS: Participants were 352 Australian parents of children aged six months to six years. Daily mealtime television use (average frequency/day) was associated with higher daily frequency of discretionary food intakes (ß 0.2, 95% confidence interval (CI) 0.07-0.67) at the 2-year follow-up. Individually, television use during breakfast and dinner (1-2 days/week compared to never) predicted higher daily intake frequency of discretionary food, ß 0.36 (95% CI 0.12-0.60) and ß 0.19 (95% CI 0.00-0.39), respectively. Similarly, 3-7 days/week of television use during breakfast and lunch predicted higher frequency of discretionary food intake, ß 0.18 (95% CI 0.02-0.37) and ß 0.31 (95% CI 0.07-0.55), respectively. Associations were not socioeconomically patterned. CONCLUSIONS: Investigating mealtime television use motivators across the socioeconomic spectrum could inform interventions targeting the high consumption of discretionary foods in children.

Association between obesity and traumatic dental injuries in pre-school children-A case-control study.

BACKGROUND/AIM: Obese children are more prone to accidents due to poorer motor skills which increase the likelihood of falls and the occurrence of traumatic dental injuries (TDIs). The aim of this study was to determine the association between overweight/obesity and TDI in pre-school children. MATERIAL AND METHODS: The case group was formed by children with TDI identified during a clinical examination (n = 262). Each pre-school child identified as a case was matched by a peer of the same age, gender and pre-school but without TDI to form the control group (n = 262). TDI was evaluated using the criteria proposed by Andreasen. The weight and height of the children were measured for the calculation of the body mass index which was plotted on the growth curve established by the World Health Organization. Socio-demographic variables were collected through questionnaires sent to the parents/guardians. Data analysis involved the determination of frequency distribution, the chi-square test and logistic regression analysis. RESULTS: The sample was composed of 253 children in each group. Among the children in the case group, 15.4% (n = 39) were overweight and 15.8% (n = 40) were obese. In the control group, 13.8% (n = 35) were overweight and 8.3% (n = 21) were obese. Children with trauma were more likely to be obese than children without trauma (OR = 2.05; 95%CI: 1.14 to 3.67; p = .016). In contrast, TDI was not associated with being overweight. A greater odds of TDI was also associated with an open bite (OR = 3.61; 95% CI: 1.64 to 7.96; p = .001) and accentuated overjet (OR = 2.19; 95% CI: 1.37 to 3.50; p = .001). CONCLUSIONS: Pre-school children with a history of dental trauma were more likely to be obese than those without a history of dental trauma whereas being overweight was not associated with TDI.

Dietary patterns of Australian pre-schoolers and associations with haem and non-haem iron intakes.

PURPOSE: To describe Australian pre-schooler dietary patterns and examine their associations with dietary iron intakes. METHODS: Dietary data of children (n = 812, 2 to < 6 years old) from the 2011-12 National Nutrition and Physical Activity Survey were collected via two non-consecutive 24-h recalls and analysed using AUSNUT 2011-13. Usual food and nutrient intakes were estimated via Multiple Source Method. Principal component analysis was used to extract dietary patterns from 32 food groups. Associations between dietary patterns and energy-adjusted iron intakes were assessed using linear regression, accounting for the complex survey design. RESULTS: Mean (SD) usual total dietary and haem iron intakes were 6.3 (1.9) and 0.5 (0.3) mg/day, respectively. Three dietary patterns were identified, explaining 14% of the variance. Pattern 1 (positive loadings for cheese, breads, fats and oils, and water) was positively associated with total dietary iron intakes (ß = 0.08, 95% CI 0.01, 0.15). Pattern 3 (positive loadings for red meat, fortified fruit and vegetable products, and sauces and spreads) was negatively associated with total dietary iron (ß = - 0.08, 95% CI - 0.14, - 0.01) and non-haem iron (ß = - 0.09, 95% CI - 0.15, - 0.02) intakes. No dietary patterns were associated with haem iron intakes. CONCLUSIONS: Three main patterns characterise Australian pre-schooler diets. The pattern with which dietary iron is positively associated is predominately characterised by non-haem iron sources and non-iron-fortified foods. Future research is required to estimate the iron bioavailability of Australian pre-schooler diets.

Whole-Genome Shotgun Sequencing for Nasopharyngeal Microbiome in Pre-school Children With Recurrent Wheezing.

Microbiome mediates early life immune deviation in asthma development. Recurrent wheeze (RW) in pre-school years is a risk factor for asthma diagnosis in school-age children. Dysbiosis exists in asthmatic airways, while its origin in pre-school years and relationship to RW is not clearly defined. This study investigated metagenomics of nasopharyngeal microbiome in pre-school children with RW. We applied whole-genome shotgun sequencing and human rhinovirus (HRV) detection on nasopharyngeal samples collected from three groups of pre-school children: (i) RW group: 16 children at-risk for asthma who were hospitalized for RW, (ii) inpatient control (IC): 18 subjects admitted for upper respiratory infection, and (iii) community control (CC): 36 children without respiratory syndromes. Sequence reads were analyzed by MetaPhlAn2 and HUMAnN2 algorithm for taxonomic and functional identification. Linear discriminant analysis effect size (LEfSe) analysis was used to identify discriminative features. We identified that Moraxella catarrhalis and Dolosigranulum pigrum were predominant species in nasopharynx. RW had lower alpha diversity (Shannon diversity index) than CC (0.48 vs. 1.07; P adj = 0.039), characterized by predominant Proteobacteria. LEfSe analysis revealed D. pigrum was the only discriminative species across groups (LDA = 5.57, P = 0.002), with its relative abundance in RW, IC, and CC being 9.6, 14.2, and 37.3%, respectively (P < 0.05). LEfSe identified five (ribo)nucleotides biosynthesis pathways to be group discriminating. Adjusting for HRV status, pre-school children with RW have lower nasopharyngeal biodiversity, which is associated with Proteobacteria predominance and lower abundance of D. pigrum. Along with discriminative pathways found in RW and CC, these microbial biomarkers help to understand RW pathogenesis.

Prevalence and risk factors of pre-schoolers' fine motor delay within vulnerable Australian communities.

AIM: This study examined the prevalence and risk factors of fine motor delay in Australian pre-school children from low-income communities. METHODS: Children from the Early Start Baseline Study completed the Ages and Stages Questionnaire (3rd edn.). Age, sex, executive function and family characteristics were assessed and associations with fine motor skills analysed. RESULTS: Data were available for 700 children (Mage 54.0 ± 8.6 months, 53.1% boys) of which 77.4% were typically developing, 12.1% at risk and 10.4% delayed for fine motor skill. Children had higher odds of being delayed if they were male (odds ratio (OR) 3.30, 95% confidence interval (CI) 2.22-4.90) or indigenous (OR 3.31, 95% CI 2.12-5.16) and had lower self-regulatory (OR 2.17, 95% CI 1.31-3.58). Higher vocabulary (OR 0.92, 95% CI 0.89-0.94), higher family income (OR 0.22, 95% CI 0.05-0.90) and family education (OR 0.25, 95% CI 0.08-0.74) were associated with lower odds of delay. CONCLUSION: Almost one in four children from vulnerable communities experience fine motor difficulties, highlighting the importance of early screening and targeting key child and environmental risk factors.

Validity and reliability testing of the Toddler and Infant (TANDI) Health Related Quality of Life instrument for very young children.

BACKGROUND: Despite the high burden of disease in younger children there are few tools specifically designed to estimate Health Related Quality of Life (HRQoL) in children younger than 3 years of age. A previous paper described the process of identifying a pool of items which might be suitable for measuring HRQoL of children aged 0-3 years. The current paper describes how the items were pruned and the final draft of the measure, Toddler and Infant (TANDI) Health Related Quality of Life, was tested for validity and reliability. METHODS: A sample of 187 caregivers of children 1-36 months of age were recruited which included children who were either acutely ill (AI), chronically ill (CI) or from the general school going population (GP). The TANDI, an experimental version of the EQ-5D-Y proxy, included six dimensions with three levels of report and general health measured on a Visual Analogue Scale (VAS) from 0 to 100. The content validity had been established during the development of the instrument. The TANDI, Ages and Stages Questionnaire (ASQ), Faces, Leg, Activity, Cry, Consolabilty (FLACC) or Neonatal Infant Pain Scale (NIPS) and a self-designed dietary information questionnaire were administered at baseline. The TANDI was administered 1 week later in GP children to establish test-retest reliability. The distribution of dimension scores, Cronbach's alpha, rotated varimax factor analysis, Spearman's Rho Correlation, the intraclass correlation coefficient, Pearson's correlation, analysis of variance and regression analysis were used to explore the reliability, and validity of the TANDI. RESULTS: Concurrent validity of the different dimensions was tested between the TANDI and other instruments. The Spearman's Rho coefficients were significant and moderate to strong for dimensions of activity and participation and significant and weak for items of body functions. Known groups were compared and children with acute illness had the lowest ranked VAS (median 60, range 0-100), indicating worse HRQoL. The six dimensions of the TANDI were tested for internal consistency and reliability and the Cronbach's α as 0.83. Test-retest results showed no variance for dimension scores of movement and play, and high agreement for pain (83%), relationships (87%), communication (83%) and eating (74%). The scores were highly correlated for the VAS (ICC = 0.76; p < 0.001). CONCLUSION: The TANDI was found to be valid and reliable for use with children aged 1-36 months in South Africa. It is recommended that the TANDI be included in future research to further investigate HRQoL and the impact of interventions in this vulnerable age group. It is further recommended that future testing be done to assess the feasibility, clinical utility, and cross-cultural validity of the measure and to include international input in further development.

Item generation for a proxy health related quality of life measure in very young children.

BACKGROUND AND AIMS: Very young children have a relatively high prevalence of morbidity and mortality. Health care and supportive technology has improved but may require difficult choices and decisions regarding the allocation of these resources in this age group. Cost-effective analysis (CEA) can inform these decisions and thus measurement of Health-Related Quality of Life (HRQoL) is becoming increasingly important. However, the components of HRQoL are likely to be specific to infants and young children. This study aimed to develop a bank of items to inform the possible development of a new proxy report instrument. METHODS: A review of the literature was done to define the concepts, generate items and identify measures that might be an appropriate starting point of reference. The items generated from the cognitive interviews and systematic review were subsequently pruned by experts in the field of HRQoL and paediatrics over two rounds of a Delphi study. RESULTS: Based on the input from the different sources, the greatest need for a new HRQoL measure was in the 0-3-year age group. The item pool identified from the literature consisted of 36 items which was increased to 53 items after the cognitive interviews. The ranking of items from the first round of the Delphi study pruned this pool to 28 items for consideration. The experts further reduced this pool to 15 items for consideration in the second round. The experts also recommended that items could be merged due to their similar nature or construct. This process allowed for further reduction of items to 11 items which showed content validity and no redundancy. CONCLUSION: The need for an instrument to measure appropriate aspects of HRQoL in infants and young children became apparent as items included in existing measures did not cover the required spectrum. The identification of the final items was based on a sound conceptual model, acceptability to stakeholders and consideration of the observability of the item selected. The pruned item bank of 11 items needs to be subject to further testing with the target population to ensure validity and reliability before a new measure can be developed.

Adequacy of iron intakes and socio-demographic factors associated with iron intakes of Australian pre-schoolers.

PURPOSE: To estimate the prevalence of inadequate iron intakes and identify socio-demographic factors associated with iron intakes of Australian children aged 2-5 years. METHODS: Data from the 2011-2012 National Nutrition and Physical Activity Survey component of the Australian Health Survey were analysed (n = 783, 2-5 years old). Dietary intake was assessed via two non-consecutive 24-h recalls. Prevalence of inadequate iron intake was estimated using the full probability approach after estimating the distribution of usual intakes with PC-SIDE. Associations between potential socio-demographic factors and energy-adjusted iron intakes were assessed via linear regression accounting for the complex survey design. RESULTS: Mean (SD) iron intakes for pre-schoolers were 7.9 (1.9) mg/day and the prevalence of inadequate iron intake was 10.1% (95% CI 7.9%, 12.1%). Male sex (mean difference between boys and girls: - 0.22 (95% CI - 0.03, - 0.41) mg/day; p = 0.022) and age (each additional year was associated with 0.11 (95% CI - 0.22, - 0.00) mg/day lower iron intake; p = 0.048) were negatively associated with pre-schooler iron intakes. CONCLUSIONS: This study provides current data relating to the iron nutrition of Australian pre-schoolers. Poor iron intakes continue to be a problem for 10% of Australian children beyond the second year of life, with iron intakes being lower for boys compared to girls and declining with age. Future research should examine strategies to improve iron intakes of young children, with a focus on promoting iron-rich food sources.

Variabilidad en el patrón de consumo de alimentos en una población de preescolares de Asunción, de nivel socioeconómico alto y su relación con el estado nutricional / The variability in feeding patterns of pre-schoolers living in Asunción, from families with high socioeconomic status and the relation with their nutritional status

Introducción: La diversidad alimentaria constituye una medida cualitativa del consumo de alimentos, tiene una asociación positiva con la calidad de la dieta y es un factor importante para alcanzar los requerimientos nutricionales. Objetivo: Evaluar la variabilidad en el patrón de consumo de los alimentos de niños pre escolares residentes en Asunción, de condición socioeconómica alta y su relación con el estado nutricional. Metodología: Diseño observacional, trasversal, cualitativo. Se realizó la evaluación de niños prescolares de 2-6 años de nivel socio económico alto de Asunción, de setiembre a octubre de 2014 mediante medición antropométrica y con dos encuestas: una de datos demográficos y otra con la lista de todos los alimentos disponibles en el mercado, mediante entrevista directa. Se evaluó estado nutricional y su relación con la diversidad alimentaria. Se utilizó medidas de frecuencia y el programa Anthro 3.2 de la Organización Mundial de la Salud. Resultados: Se estudiaron 67 niños, con predominó del sexo femenino. El 89,5 % de madres tuvo estudios terciarios concluidos. Se encontraban eutróficos (63% de los niños) y 31,5 % con malnutrición por exceso (sobrepeso y obesidad) Un 19% presentó riesgo de talla baja y el 1,5% talla baja. Se hallaron un total de 172 tipos de alimentos que se distribuyeron en 9 grupos, la media de número de alimentos consumidos por los niños pre escolares fue de 69,19 (IC 95%: 63,79- 74,59). El rango mínimo fue de 28 alimentos y el máximo 126 alimentos. No se encontró diferencias significativas con el Índice de Masa Corporal y la diversidad alimentaria; sin embargo la relación fue estadísticamente significativa entre diversidad de la alimentación y la talla alta. Conclusión: Se constató que existe poca variabilidad en el consumo de alimentos de niños pre escolares sin restricción socio económica. Se encontró relación significativa entre diversidad Alimentaria y la talla del niño

Introduction: Food diversity can be used to measure the quality of the feeding habits. It has a positive association with diet quality and constitutes an important factor to reach the nutritional requirements. Objectives: Assess the variability in feeding patterns of pre-schoolers living in Asunción, from families with high socioeconomic status and the relation with their nutritional status. Methodology: Observational, transversal in time, qualitative study. The researchers evaluated children from 2-6 years of age, from families with high socioeconomic status living in Asunción, from September to October of 2014, using antromopetric measures and two questionnaires applied in direct interview format: the first one with demographic data and the second one with a list of locally available food. The nutritional status and its relation with food diversity were assessed, measuring frequency. World's Health Organization's Software Anthro 3.2 was used for anthropometric evaluation. Results: In total, 67 children were included in the study, mainly female. 89,5% of the patient's mother had concluded tertiary education. 63% of patients were well-nourished and 31,5% had excess weight (overweight and obese). 19% were in risk of stumpting and 1,5% were in the range of stumpting. A total of 172 food varieties were found, distributed in 9 groups, the mean quantity of food varieties consumed by children was of 69,19 (CI: 95%, 63,79-74,59), ranging from 28 to 126 food varieties. Significant differences were not found in Body Mass Index and food diversity; but a statistically significant relation was found between food diversity and height. Conclusion: Low variability in feeding patterns was found in children with high socioeconomic status. There was a significant relation between food diversity and the child's height

Titanium mesh cranioplasty in pediatric patients after decompressive craniectomy: Appropriate timing for pre-schoolers and early school age children.

PURPOSE: There is little knowledge on the growth of cranial defects, appropriate timing and outcomes of application of titanium mesh for cranioplasty in the pediatric population, especially pre-school age (2-5 years old) and school age (6-12 years old) children. We hypothesised that cranioplasty for pre-schoolers could be delayed to school age due to the expected cranium growth, whereas, for the school age group, it is better to perform routine cranioplasty (3-6 months) to protect the brain and therefore ensure their timely return to school life. MATERIALS AND METHODS: A retrospective review of pediatric patients (2-12 years old) who underwent titanium mesh cranioplasty for cranial defects from 2006 to 2012 was performed. Patient demographic data, radiological data, and clinical information were collected. Specifically, cranial defect sizes were evaluated by three-dimensional (3D) reconstruction of computed tomography data after craniectomy, before cranioplasty and 2-years after cranioplasty. Patients were routinely followed up at an outpatient clinic for complications and school attendance. RESULTS: A total of 18 titanium mesh cranioplasties were performed in 18 patients. The average interval between craniectomy and cranioplasty was 3 years for pre-schoolers and 4 months for the school age group. Patients in the pre-schooler group showed significant enlargements in cranial defects during the interval as compared with the school age group (26% vs. 4%, P < 0.05). There were no surgery-related complications except in one patient, who had titanium mesh exposure 11 months later. Two years after cranioplasty, there was no significant difference in mild cranial defect enlargements between the two groups (11% vs. 6%, P > 0.05). Patients were followed for an average of 5 (range, 2-8) years. All patients had satisfactory recovery of cranial contour, sufficient protection of the brain and active participation in school study. All patients had satisfactory recovery of cranial contour, sufficient protection of the brain and active participation in school. CONCLUSION: Timing of titanium mesh cranioplasty after decompressive craniectomy based on their age is a workable solution for school-age pediatric patients. The enlargement of cranium defects in pre-schoolers supports a delayed repair until school age. The long-term outcomes for these patients with titanium mesh cranioplasty are favourable.

Characteristics of Effective Interventions Promoting Healthy Eating for Pre-Schoolers in Childcare Settings: An Umbrella Review.

Early Childhood Education and Care (ECEC) settings have a pivotal role in shaping children's dietary food habits by providing the contextual environment within which they develop these behaviours. This study examines systematic reviews for (1) the effectiveness of interventions to promote healthy eating in children aged 2-5 years attending centre-based childcare; (2) intervention characteristics which are associated with promoting healthy eating and; (3) recommendations for child-health policies and practices. An Umbrella review of systematic reviews was undertaken using a standardized search strategy in ten databases. Twelve systematic reviews were examined using validated critical appraisal and data extraction tools. Children's dietary food intake and food choices were significantly influenced. Interventions to prevent obesity did not significantly change children's anthropometric measures or had mixed results. Evidence was more convincing if interventions were multi-component, addressed physical activity and diet, targeted individual-level and environmental-level determinants and engaged parents. Positive outcomes were mostly facilitated by researchers/external experts and these results were not replicated when implemented in centres by ECEC providers without this support. The translation of expert-led interventions into practice warrants further exploration of implementation drivers and barriers. Based on the evidence reviewed, recommendations are made to inform child-health directed practices and policies.

Does maternal psychopathology increase the risk of pre-schooler obesity? A systematic review.

The preschool years may be a critical period for child obesity onset; however, literature examining obesity risk factors to date has largely focused on school-aged children. Several links have been made between maternal depression and childhood obesity risks; however, other types of maternal psychopathology have been widely neglected. The aim of the present review was to systematically identify articles that examined relationships between maternal psychopathology variables, including depressive and anxiety symptoms, self-esteem and body dissatisfaction, and risks for pre-schooler obesity, including weight outcomes, physical activity and sedentary behaviour levels, and nutrition/diet variables. Twenty articles meeting review criteria were identified. Results showed positive associations between maternal depressive symptoms and increased risks for pre-schooler obesity in the majority of studies. Results were inconsistent depending on the time at which depression was measured (i.e., antenatal, postnatal, in isolation or longitudinally). Anxiety and body dissatisfaction were only measured in single studies; however, both were linked to pre-schooler obesity risks; self-esteem was not measured by any studies. We concluded that maternal depressive symptoms are important to consider when assessing risks for obesity in preschool-aged children; however, more research is needed examining the impact of other facets of maternal psychopathology on obesity risk in pre-schoolers.

Estudio preliminar del impacto socioeconómico sobre los puntajes de una batería multidimensional de aptitudes en niños preescolares / A preliminary study on the socioeconomic impact on the scores of a set of multidimensional aptitude tests in pre-school children

El presente estudio explora las relaciones entre nivel socioeconómico, género y tipo de centro educativo preescolar y el desempeño cognitivo de niños preescolares (N = 323) de Lima (Perú), con una prueba multidimensional de aptitudes. Con la aplicación de la técnica multivariada de análisis de perfiles se hallaron diferencias estadísticamente significativas y de moderada magnitud del efecto en los puntajes cognitivos, debidas a la ubicación del centro educativo; no se detectaron diferencias que se atribuyan al género y al tipo de centro. Se trabajó en base a tres hipótesis: La primera es la hipótesis de igualdad de niveles, en la que se examinan las diferencias que en promedio existen entre los dos grupos. La segunda es la hipótesis de igualdad de la dispersión, que examina si las variables de respuesta (puntajes en las subescalas) tienen la misma respuesta en promedio. Y la tercera, la hipótesis de paralelismo, que prueba si el patrón de elevaciones en el perfil es similar entre los dos grupos. Los resultados fueron evaluados con respecto a la consistencia interna y a la definición del nivel socioeconómico (ubicación geográfica). Se discuten las diferencias halladas en el aspecto socioeconómico y relacionándolas con la bibliografía sobre el tema y la utilidad de la batería multidimensional de aptitudes para niños preescolares. Es importante destacar que el estudio reporta información normativa acerca del desempeño de los niños preescolares, en lo que respecta al género y ubicación de los centros educativos y su carácter correlacional y la magnitud del efecto de los resultados.

The present study explores the relationship between socioeconomic level, gender and type of pre-school education center, and cognitive development in 323 pre-schoolers in Lima (Perú), using a multidimensional aptitude test. By applying the multivariate technique, we found statistical significant differences and medium size effects on the cognitive scores due to the educational center location, whereas gender and type of educational center differences were not found. The results were considered taking into account reliability levels and also according to the definition of socioeconomic levels. The differences found are discussed based on other articles as well as on the usefulness of the multidimensional aptitude tests for pre-schoolers. The sample consisted of 323 children of 5 years old, 167 boys and 156 girls, who go to both private and public pre-schools in a district of Lima. The proportion of public pre-school students (67.2%) was double the amount of private pre-school students (32.8%). Moreover, the private pre-schools had been recently formed (4 to 5 years before) and had children from families with a medium or medium to low socioeconomic level. In order to assess general and relevant aspects of pre-school learning, we applied a pre-school diagnostic test (De la Cruz, 1991), which can be used at a pre-school level (4-5 year-olds). This test contains the following areas: Verbal concepts, Quantitative concepts and Auditive memory, Visual perceptual aptitude and Visual-motor coordination. It is a potentia test because the time varies from one student to another so as to allow every child to answer every item. Furthermore, it is also a maximum performance test because the student tries to obtain the best possible score. We contacted several educational centers (private and public) from three different districts in Lima which accepted to participate in this study. The time of application of the test varied considering: individual skills, the number of children in the collective application, the presence of a teacher's aide for the collective application, and the attitude and motivation of the students. We used MANOVA to analyze profiles, a post hoc univariate contrast, and effect size estimations such as Cohen's d. Our study was based on three hypotheses: The first hypothesis was on the equality of levels (variability between subjects) that explores the differences that exist between both groups separately. As a result, we found no correlation between test performance and gender or school location. However, when considering type of school (public or private), we did find significant differences in one scale: Auditive memory, which was higher in public schools. The second hypothesis was the equality of dispersion (within-group differences), to identify if the answer variables have the same answers on average. We found similarities regarding school conditions (public or private); but there were small differences between gender and school location. The third hypothesis was regarding parallelism, which tests whether the pattern of elevations on the profile is similar between the two groups or not. We did not find important statistical dispersions and the effect size was small. The results coincide with other studies on the correlation between gender and socioeconomic level, and cognitive development. Among some of the limitations of our study, we list the following: for example, we used the school location to determine the children's socioeconomic level. Therefore, there were also extreme scores (outliers), which could vary the central tendency estimations and the dispersion. However, they were not trimmed, since in a previous unreported analysis without these data, researchers found only minimum changes. We also had occasional difficulties in applying the tests, due to the children's disposition to participate as well as their reaction concerning the test situation, which could have added random error on the results. However, we presume their negative reactivity was reduced because of the playful manner in which the tests were presented. The results of our research shed normative information regarding the performance of preschoolers due to gender and location of their educational centers. It is important to emphasize correlations as well as effect size of the results so as not to reach erroneous conclusions.
