Unfavorable food consumption in children up to school entry age: results from the nationwide German KiESEL study.

Introduction: Evidence points toward the early life being crucial for preventing nutrition-related diseases. As promotion of healthier food preferences in toddlerhood and preschool age might still modulate the trajectories of disease risk, understanding diet in these age groups is necessary. The objective was to analyze food consumption and diet quality of 1-5-year-old children living in Germany in relation to age and sex. Methods: Data from 890 children, a subsample of the representative, cross-sectional Children's Nutrition Survey to Record Food Consumption (KiESEL) conducted by the German Federal Institute for Risk Assessment in 2014-2017, were analyzed. Dietary data were collected using food records (3 consecutive plus 1 independent day). Diet quality was evaluated against the German food-based dietary guidelines (FBDG). Results: Consumption of unfavorable foods (e.g., sweets, soft drinks) exceeded the recommended maximum of 10% of energy intake (E%) by a multiple in all age and sex groups (medians: 24.8-35.8 E%). Preschoolers consumed more unfavorable foods than toddlers and boys more than girls. More than half of the children exceeded the recommendation for meat intake (medians: 2.3-3.2% of the total food consumption (%TFC) vs. 2 %TFC), especially preschoolers. In nearly all children, vegetable consumption was too low (medians: 4.2-4.5 %TFC vs. 12 %TFC). Also, milk/milk product consumption was below recommendations, more so in preschoolers (median: 12.0 %TFC ♂, 11.9 %TFC ♀ vs. 18 %TFC) than in toddlers (median: 16.1 %TFC ♂, 19.6 %TFC ♀). In toddlers and preschoolers with overweight or obesity, adherence to dietary recommendations of these food groups was largely similar to that of the total sample. Overall, 5-year-olds showed an unhealthier dietary pattern than 1-year-olds, which already emerged at age 2 years and became more evident at age 3 years. Discussion: An adverse dietary pattern arises and even deteriorates at a very young age, showing sex-specific aspects. High attention from public health and research needs to be given to toddlerhood and even earlier life phases, e.g., to develop more age-specific FBDGs, aiming at reducing unhealthy food consumption.

Improving Parental Health Literacy in Primary Caregivers of 0- to 3-Year-Old Children Through a WeChat Official Account: Cluster Randomized Controlled Trial.

Background: Parental health literacy is important to children's health and development, especially in the first 3 years. However, few studies have explored effective intervention strategies to improve parental literacy. Objective: This study aimed to determine the effects of a WeChat official account (WOA)-based intervention on parental health literacy of primary caregivers of children aged 0-3 years. Methods: This cluster randomized controlled trial enrolled 1332 caregiver-child dyads from all 13 community health centers (CHCs) in Minhang District, Shanghai, China, between April 2020 and April 2021. Participants in intervention CHCs received purposefully designed videos via a WOA, which automatically recorded the times of watching for each participant, supplemented with reading materials from other trusted web-based sources. The contents of the videos were constructed in accordance with the comprehensive parental health literacy model of WHO (World Health Organization)/Europe (WHO/Europe). Participants in control CHCs received printed materials similar to the intervention group. All the participants were followed up for 9 months. Both groups could access routine child health services as usual during follow-up. The primary outcome was parental health literacy measured by a validated instrument, the Chinese Parental Health Literacy Questionnaire (CPHLQ) of children aged 0-3 years. Secondary outcomes included parenting behaviors and children's health outcomes. We used the generalized linear mixed model (GLMM) for data analyses and performed different subgroup analyses. The ß coefficient, risk ratio (RR), and their 95% CI were used to assess the intervention's effect. Results: After the 9-month intervention, 69.4% (518/746) of caregivers had watched at least 1 video. Participants in the intervention group had higher CPHLQ total scores (ß=2.51, 95% CI 0.12-4.91) and higher psychological scores (ß=1.63, 95% CI 0.16-3.10) than those in the control group. The intervention group also reported a higher rate of exclusive breastfeeding (EBF) at 6 months (38.9% vs 23.44%; RR 1.90, 95% CI 1.07-3.38) and a higher awareness rate of vitamin D supplementation for infants younger than 6 months (76.7% vs 70.5%; RR 1.39, 95% CI 1.06-1.82). No significant effects were detected for the physical score on the CPHLQ, breastfeeding rate, routine checkup rate, and children's health outcomes. Furthermore, despite slight subgroup differences in the intervention's effects on the total CPHLQ score and EBF rate, no interaction effect was observed between these subgroup factors and intervention factors. Conclusions: Using a WHO literacy model-based health intervention through a WOA has the potential of improving parental health literacy and EBF rates at 6 months. However, innovative strategies and evidence-based content are required to engage more participants and achieve better intervention outcomes.

RSV Prevention Within Reach for Older Infants and Toddlers: The Role of Active Immunization.

This review article will summarize the vaccines and monoclonal antibodies currently under evaluation for the prevention of RSV disease in older infants, toddlers and young children. We will review the rationale for passive protection during the first months of life, and the role of active immunization afterwards, either with live attenuated, protein-based or mRNA vaccines.

Association between neural prosody discrimination and language abilities in toddlers: a functional near-infrared spectroscopy study.

BACKGROUND: Language delay affects near- and long-term social communication and learning in toddlers, and, an increasing number of experts pay attention to it. The development of prosody discrimination is one of the earliest stages of language development in which key skills for later stages are mastered. Therefore, analyzing the relationship between brain discrimination of speech prosody and language abilities may provide an objective basis for the diagnosis and intervention of language delay. METHODS: In this study, all cases(n = 241) were enrolled from a tertiary women's hospital, from 2021 to 2022. We used functional near-infrared spectroscopy (fNIRS) to assess children's neural prosody discrimination abilities, and a Chinese communicative development inventory (CCDI) were used to evaluate their language abilities. RESULTS: Ninety-eight full-term and 108 preterm toddlers were included in the final analysis in phase I and II studies, respectively. The total CCDI screening abnormality rate was 9.2% for full-term and 34.3% for preterm toddlers. Full-term toddlers showed prosody discrimination ability in all channels except channel 5, while preterm toddlers showed prosody discrimination ability in channel 6 only. Multifactorial logistic regression analyses showed that prosody discrimination of the right angular gyrus (channel 3) had a statistically significant effect on language delay (odd ratio = 0.301, P < 0.05) in full-term toddlers. Random forest (RF) regression model presented that prosody discrimination reflected by channels and brain regions based on fNIRS data was an important parameter for predicting language delay in preterm toddlers, among which the prosody discrimination reflected by the right angular gyrus (channel 4) was the most important parameter. The area under the model Receiver operating characteristic (ROC) curve was 0.687. CONCLUSIONS: Neural prosody discrimination ability is positively associated with language development, assessment of brain prosody discrimination abilities through fNIRS could be used as an objective indicator for early identification of children with language delay in the future clinical application.

Assessment of Water Intake among Chinese Toddlers: The Report of a Survey.

Toddlerhood (aged 13~36 months) is a period of dietary transition, with water intake being significantly influenced by parental feeding patterns, cultural traditions, and the availability of beverages and food. Nevertheless, given the lack of applicable data, it is challenging to guide and evaluate the water intake of toddlers in China. In this study, our objectives were to assess the daily total water intake (TWI), evaluate the consumption patterns of various beverages and food sources contributing to the TWI, determine the conformity of participants to the adequate intake (AI) recommendation of water released by the Chinese Nutrition Society, and analyze the various contributors to the daily total energy intake (TEI). The data for the assessment of water and dietary intake were obtained from the cross-sectional dietary intake survey of infants and young children (DSIYC, 2018-2019). A total of 1360 eligible toddlers were recruited in the analysis. The differences in related variables between two age groups were compared by Mann-Whitney U test and Chi-Square test. The potential correlation between water and energy intake was examined utilizing age-adjusted partial correlation. Toddlers consumed a median daily TWI of 1079 mL, with 670 mL (62.3%, r = 0.752) derived from beverages and 393 mL (37.7%, r = 0.716) from foods. Plain water was the primary beverage source, contributing 300 mL (52.2%, r = 0.823), followed by milk and milk derivatives (MMDs) at 291 mL (45.6%, r = 0.595). Notably, only 28.4% of toddlers managed to reach the recommended AI value. Among these, toddlers obtain more water from beverages than from foods. The median daily TEI of toddlers was 762 kcal, including 272 kcal from beverages (36.4%, r = 0.534) and 492 kcal from foods (63.6%, r = 0.894). Among these, the median daily energy intake from MMDs was 260 kcal, making up 94.6% of the energy intake from beverages (r = 0.959). As the pioneer survey on TWI of toddlers in China based on nationally representative data, attention to the quality and quantity of water intake and actions to better guide parents by both individuals and authorities are eagerly anticipated. Additionally, the revision of the reference value of TWI for Chinese toddlers is urgently required.

Development of a culturally enhanced caregiver-facilitated language nutrition intervention "+Language is Medicine" to address developmental delay in Diné (Navajo) toddlers.

Introduction: Developmental Delay (DD) is highly common in American Indian and Alaska Native (AI/AN; Indigenous) toddlers and leads to high numbers of AI/AN children who eventually need special education services. AI/AN children are 2.89 times more likely to receive special education compared to other children in the U.S., yet developmental disorders are more frequently under diagnosed and untreated in AI/AN infants and toddlers. DD, which can be identified as early as toddlerhood, can lead to negative impacts on developmental trajectories, school readiness, and long-term health. Signs of DD can be identified early with proper developmental screening and remediated with high quality early intervention that includes effective parent training. There are many evidence-based language facilitation interventions often used in Early Intervention programs. However, in communities in rural parts of the Navajo Nation where there are limited services and resources, infants and toddlers with early signs of DD are often missed and do not get the culturally responsive support and evidence-based intervention they deserve. Methods: The community-based +Language is Medicine (+LiM) study team partnered with tribal home visitors, community members, and a Diné linguist/elder using a collaborative virtual workgroup approach in 2021 and 2022 to present the +LiM pilot study aims and to discuss strategies for enhancing a language intervention for toddlers experiencing DD in their tribal community. This paper will detail the stages of community engagement, intervention enhancement and preparation for field testing of the +LiM intervention to address elevated rates of DD in toddlers in the Northern Agency of the Navajo Nation. Results: Two major outcomes from this collaborative workgroup included: (1) a team-initiated redefining of language nutrition to align with Indigenous values that center cultural connectedness and native language use and (2) a five-lesson caregiver-facilitated curriculum titled +Language is Medicine which includes caregiver lessons on language nutrition, language facilitation, shared book reading, pretend play, and incorporation of native language into home routines. These two workgroup outcomes were leveraged to develop a pilot pre-/post-intervention study to test the effectiveness of the +LiM intervention with caregiver-toddler dyads living on the Navajo Nation. Discussion: Delivering tailored child interventions through tribal home visiting are cost-effective and innovative methods for reaching reservation-based families who benefit from culturally responsive parent coaching and instruction. The +LiM team has applied a precision tribal home visiting approach to enhance methods of early intervention for children with DD. Our enhancement process was grounded in Indigenous community-based participatory research that centered culture and language.

Possible relationship between respiratory diseases and urinary concentrations of polycyclic aromatic hydrocarbon metabolites - a pilot study.

This study investigates the potential relationship between exposure to polycyclic aromatic hydrocarbons (PAHs), specifically monohydroxylated metabolites (OH-PAHs), in urine, and the prevalence of respiratory diseases in 2-year-old children residing in two locations within the Czech Republic - Ceské Budejovice (control location) and the historically contaminated mining district of Most. Despite current air quality and lifestyle similarities between the two cities, our research aims to uncover potential long-term health effects, building upon previous data indicating distinctive patterns in the Most population. A total of 248 urine samples were analysed for the presence of 11 OH-PAHs. Employing liquid-liquid extraction with ethyl acetate and clean-up through dispersive solid-phase extraction, instrumental analysis was conducted using ultra-high performance liquid chromatography coupled with tandem mass spectrometry. The incidence of respiratory diseases was assessed through questionnaires administered by paediatricians. The concentrations of OH-PAHs were elevated in urine samples from 2-year-olds in Most compared to those from Ceské Budejovice. The incidence of respiratory diseases showed statistically significant higher levels of OH-PAHs in children from Most, together with a higher incidence of influenza. This association underlines the impact of environmental PAH exposure on children's respiratory health. It suggests that elevated urinary OH-PAH levels indicate an increased risk of developing respiratory diseases in the affected population. Further studies are needed to clarify the possible long-term health effects and to contribute to sound public health strategies.

Comparing the Implementation Context for Early Intervention Services Before and During the COVID-19 Pandemic.

The COVID-19 pandemic not only led to drastic changes in the implementation context for early intervention and early childhood special education services in 2020, but has had an enduring effect on the organizations, educators, families, and children with developmental delays and disorders. Through secondary data analysis, characteristics of toddlers with autism being served in a publicly funded center-based early intervention program as well as the characteristics of their educators are examined, comparing those who were enrolled in (a) two randomized trials conducted prior to the pandemic and (b) one ongoing randomized trial that launched in return to in-person educational services after the pandemic shutdown. Significant demographic differences are found for toddlers, where the current study includes more girls (p = 0.002), who are younger (p < .001) than the prior studies. Further, toddlers enrolled in the current trial are entering with significantly younger receptive (p < .001) and expressive language age-equivalent scores (p < .001) than toddlers from the prior studies. In addition, significant differences are also found for teaching assistants (TAs), who are younger (p < .001), less experienced supporting children with autism (p < .001), have spent less time in this position (p < .001), and who are still working toward college degrees (p < .001) than TAs in the prior studies. Implications of these changes for both intervention strategies to support the strengths and needs of the toddlers (e.g., reduce frequency of TA-child pairing changes to build rapport, increase time in adult-child JASPER before adding peers) as well as implementation strategies (e.g., increase foundational content, TA teaming) to support the training and retention of the TAs are discussed. Clinical Trials Registry number: NCT04283045.

The clinical value of ultrasound in assessing ovarian strangulation in female infants and toddlers with ovarian hernia.

Objective: To explore the clinical value of ultrasound examination in evaluating the presence of ovarian torsion in female infants with inguinal ovarian hernia. Methods: We conducted a retrospective analysis of 91 cases of ovarian hernia diagnosed by ultrasonography at our institution. Among them, 6 cases were identified as ovarian strangulation, while 85 cases were classified as non-ovarian strangulation. All cases underwent high-frequency ultrasound examination. We analyzed whether there were differences in the associated factors between the two groups and compared the disparities in the urgency of surgery between the two groups. Results: Significant differences were observed between the ovarian strangulation group and the non- strangulation group in terms of ovarian volume, ovarian blood flow, and the presence of incarceration. The need for emergency surgery was significantly associated with the presence of incarceration and ovarian torsion. Conclusion: Ultrasound has good clinical value in diagnosing ovarian hernia and determining the presence of ovarian strangulation. It can assist clinical physicians in determining the timing of surgery for children with ovarian hernia.

Melatonin use in infants and toddlers.

Background Melatonin use in the pediatric population is on the rise in the United States, where it is available as an over-the-counter and online supplement. There are no data regarding the safety and efficacy of melatonin in children less than 2 years old. The aim of this study was to examine various aspects of melatonin use by caregivers of infants and toddlers in the US. Methods Caregiver users of the Nanit baby monitoring system with a child aged 0-36 months were invited to complete an online survey regarding melatonin use, sources of information/recommendations about melatonin, formulations used and reasons for administering melatonin to their child. Participants also completed the Brief Infant Sleep Questionnaire-Revised (BISQ-R). Results A total of 3063 caregivers (1.93%) responded to the survey, of whom 1.7% had ever used melatonin for their child. About half of those caregivers had received a recommendation for melatonin from a source other than a healthcare professional. Caregiver perception of 'sleep as a problem' as assessed by the BISQ-R was not significantly different between those who had or had not used melatonin for their child, and reasons for use included non-supported indications such as sleeping later or promoting "more restful and better sleep". Conclusions The results of this study support mounting concerns regarding the widespread use of melatonin in the US pediatric population, especially given the lack of regulatory oversight and the documented inaccuracy of label claims versus actual melatonin content.

Usual Choline Intake of Australian Children 6-24 Months: Findings from the Australian Feeding Infants and Toddlers Study (OzFITS 2021).

(1) Background: Despite the important role choline plays in child development, there are no data on dietary choline intake in early childhood in Australia. (2) Aim: In this cross-sectional study, we estimated the usual total choline intake and the proportion exceeding the Adequate Intake (AI) and determined the main dietary sources of choline in infants 6-12 months (n = 286) and toddlers 12-24 months (n = 475) of age. (3) Methods: A single 24-h food record with repeats collected during the 2021 Australian Feeding Infants and Toddlers Study (OzFITS 2021) was used to estimate dietary choline intake. (4) Results: The mean choline intake was 142 ± 1.9 mg/day in infants and 181 ± 1.2 mg/day in toddlers. Only 35% of infants and 23% of toddlers exceeded the AI for choline based on Nutrient Reference Values (NRVs) for Australia and New Zealand. Breastmilk was the leading source of choline, contributing 42% and 14% of total choline intake in infants and toddlers, respectively; however, egg consumers had the highest adjusted choline intakes and probability of exceeding the AI. (5) Conclusions: Findings suggest that choline intake may be suboptimal in Australian infants and toddlers. Further research to examine the impact of low choline intake on child development is warranted.

Nutritional counselling and risk factors for obesity: an observational study in toddlers.

BACKGROUND: Nutrition exerts a fundamental role in the prevention of obesity (OB). The aim of this study was to assess the extent to which well recognized risk factors for early OB can be associated to overweight (OW) or OB under a standardized nutritional approach and surveillance in toddlers. METHODS: The eligible population was represented by 676 toddlers aged 24-36 months, assigned to 18 primary care pediatricians trained on nutritional issues who shared a standardized nutritional approach. Six-hundred-twenty-nine children (333 boys), mean age 27.8 ± 4.2 months were effectively included in this observational study. Parents received nutritional advice with particular emphasis to proteins and sugar composition supported by leaflets and reinforced at each visit. Body mass index was assessed at the age of 24-36 months. The following individual and family risk factors were considered: gestational age, birth weight, eutocic/caesarean delivery, milk feeding history, household smoking or antibiotics exposure, parents' weight, height and educational level. Prevalence of OW/OB was compared to a group of 742 toddlers (373 boys) under usual care. RESULTS: Under a standardized nutritional counselling, 28.1% toddlers were classified as OW/OB compared to 36.9% toddlers under usual care (p = 0.005). In unadjusted models, parental OW/OB was significantly associated to OW/OB in toddlers (p < 0.01), while high birth weight did not reach statistical significance (p = 0.07). In adjusted models, including all the explanatory variables studied, only paternal OW/OB vs. normal weight was significantly associated to OW/OB in toddlers (OR 2.035, 95% confidence interval 1.206-3.436). No protective effect of exclusive breast feeding during the first 6 months of age was demonstrated. CONCLUSIONS: Toddlers under a standardized nutrition counselling focused to limit protein and simple sugars, showed lower prevalence of OW/OB compared to usual care. Healthy promotion activities should take into account the influence of paternal BMI on the offspring adiposity.

Complementary food exposure and children's early understanding of food words: the approaching eating through language (APPEAL) study.

Introduction: Language skills, such as the ability to understand words (receptive language), develop during infancy and are built through interactions with the environment, including eating. Exposure to complementary foods also begins in infancy and may play a significant role in language development, especially in understanding of food-related words. However, the relationship between the complementary foods to which a child is exposed and early language acquisition has not been previously studied. We hypothesized that young children's food-related receptive language (FRL) would reflect the complementary foods to which they were frequently offered by caregivers. Methods: Caregivers of young children (4-26 months; n = 408) in the Approaching Eating through Language (APPEAL) Study in the US were surveyed via Qualtrics. FRL was assessed by caregiver-report via a modified MacArthur-Bates Communicative Development Inventory. Complementary foods offered (CFO) by caregivers were assessed using a modified Food Frequency Questionnaire. Latent Class Analysis (LCA) was implemented to identify, 1) groupings of foods frequently offered (>1x/week) and 2) groupings of food-related words understood by the young children. Results: A 5-class best fit LCA model was identified for CFO (-log likelihood [-llik]=-8727) and for FRL (-llik=-5476). Cross-classification of the CFO and FRL derived classes revealed that children with higher exposure to complementary foods were perceived by caregivers to be most likely to also understand a greater number of food-related words (Probability=0.48). As expected, children having been offered a greater number of complementary foods and who understood a greater number of food-related words were older, compared to those with less complementary food exposure and food-related language acquisition (p < 0.001). Discussion: These findings support the potential role of introduction to complementary foods in development of food-related language.

A lifestyle screening tool for young children in the community: needs and wishes of parents and youth healthcare professionals.

BACKGROUND: Youth healthcare has an important role in promoting a healthy lifestyle in young children in order to prevent lifestyle-related health problems. To aid youth healthcare in this task, a new lifestyle screening tool will be developed. The aim of this study was to explore how youth healthcare professionals (YHCP) could best support parents in improving their children's lifestyle using a new lifestyle screening tool for young children. METHODS: We conducted four and seven focus groups among parents (N = 25) and YHCP (N = 25), respectively. Two main topics were addressed: the experiences with current practice of youth healthcare regarding lifestyle in young children, and the requirements for the lifestyle screening tool to be developed. The focus groups were recorded, transcribed verbatim and analysed using an inductive approach. RESULTS: Both parents and YHCP indicated that young children's lifestyles are often discussed during youth healthcare appointments. While parents felt that this discussion could be more in-depth, YHCP mainly needed clues to continue the discussion. According to parents and YHCP, a new lifestyle screening tool for young children should be easy to use, take little time and provide courses of action. Moreover, it should be attractive to complete and align with the family concerned. CONCLUSIONS: According to parents and YHCP, a new lifestyle screening tool for young children could be useful to discuss specific lifestyle topics in more detail and to provide targeted advice.

Verbal and non-verbal skills in early childhood: dimensionality, developmental trajectories, and gender differences.

This study examines the dimensionality of and relationships between two subscales from the British Ability Scales - Third Edition, measuring verbal (expressive vocabulary) and non-verbal (reasoning) cognitive skills for toddlers (age three) and preschoolers (age five), in a Norwegian context across genders. Descriptive statistics revealed item selection criteria that included specific items within each subscale. Subsequently, Confirmatory Factor Analysis established the subscales' dimensionality (Naming Vocabulary and Picture Similarities; N = 1094) and confirmed measurement invariance across genders. Further, the relationships between the verbal and non-verbal factors were investigated using correlation analysis and Structural Equation Modeling. The findings revealed that the verbal factor at age three strongly predicted the verbal factor at age five and significantly influenced the non-verbal factor at age five. The non-verbal factor at age three exhibited a moderate predictive relationship with the non-verbal factor at age five, and did not significantly predict the verbal factor at age five. In terms of gender differences, girls showed higher scores on the verbal factor at age three, and a stronger correlation between the non-verbal factor at age three and the verbal factor at age five. In summary, this research provides valuable insights into cognitive skill measurement and development in a Norwegian context and highlights possible variations across gender. The study's findings, limitations, and implications are discussed.

Investigation of the Effects of Maternal Nutrition during Pregnancy on Cognitive Functions of Toddlers: A Systematic Review.

Background: Growing the human brain requires all necessary nutrients to form and maintain, so the development of cognitive functions of infants and children depends on adequate nutrition. Children whose mothers had inadequate nutrition are at high risk for cognitive dysfunction. The objective of the present study was to review the studies conducted on "the relationship between nutrient intake during pregnancy and the development of cognitive functions in toddlers". The present study was conducted by systematic review method using PRISMA checklist items. Methods: To conduct this study, the keywords "maternal nutrition", "pregnancy diet", "pregnancy supplement", "IQ", "intelligence quotient", "neurodevelopment", "cognitive function", "toddler", "early years" and "infant" were searched based on the Mesh database in scientific databases including Scopus, SID, Google Scholar, PubMed, and Science Direct to find articles related to the effect of nutrition during pregnancy on the development of the cognitive function of toddlers and its components in Persian and English. Finally, 17 articles were selected for review in this study. Results: The results showed that taking a supplement of iron, saturated fatty acids, vitamins B and D, and folic acid improved the cognitive functions of toddlers. On the other hand, taking supplements containing iodine and zinc had no significant effect on the development of cognitive functions. Diets containing seafood during pregnancy had a beneficial effect on the cognitive functions of children. Conclusions: The study results highlighted the importance of adequate nutrition during pregnancy and showed that maternal nutrition played an important role in the development of cognitive functions of toddlers.

Human Milk Feeding and Ultraprocessed Food Intake in Toddlerhood.

Objective: The objective of the study was to estimate associations between early-life human milk feeding and ultraprocessed food (UPF) intake at two timepoints during toddlerhood among children born at <35 weeks' gestation. Study Design: Children were enrolled in the Omega Tots trial (2012-2017, Ohio) at 10-17 months' corrected age after having discontinued human milk and formula feeding. Caregivers reported children's human milk feeding history at baseline and past month diet through a food frequency questionnaire at baseline and follow-up (180 days later). We used the NOVA classification system to estimate UPF intake. We estimated covariate-adjusted associations between human milk feeding (ever and duration) and UPF intake at baseline and follow-up using linear and logistic regression. Results: Nearly 89% (n = 295) of 333 toddlers had received human milk but only 4.2% (n = 14) were fed exclusively human milk to 6 months of age. UPFs represented 37.7 (standard deviation [SD] = 13.2)% and 43.4 (SD = 11.3)% of total calories at the two timepoints. Human milk feeding (exclusive or otherwise) was unassociated with UPF intake in toddlerhood (e.g., months of exclusive human milk feeding with the number of daily servings of UPFs at follow-up: ß=-0.09, 95% confidence interval [CI]: -0.26, 0.08). Conclusion: In this sample of toddlers born preterm, any exposure to as well as the duration of human milk feeding was unassociated with UPF intake during the second year of life. These results require replication in larger samples given the small number of children in some human milk feeding categories.

Difficult Toddler Temperament - Prevalence and Associated Factors at 18-Month Follow-Up of a Birth Cohort.

Purpose: Difficult temperament coupled with other risk factors may lead to mental health problems in childhood and have long-lasting effects in adolescence and adulthood. This study aimed to investigate the prevalence of parental perception of difficult temperament in toddlers and identify significant factors associated with individual and family-level sociodemographic risk factors. Patients and Methods: The prevalence of parental perception of difficult temperament was derived from items in the 18-month follow-up questionnaire within the Watch Me Grow (WMG) longitudinal birth cohort study in a multicultural and socioeconomically disadvantaged community in Sydney, Australia. Data was available for 500 children and their parents. Descriptive analysis was used to calculate the participant characteristics and the prevalence of parental perception of difficult temperament, whereas multivariable logistic regression analysis was used to assess significant risk factors associated with a difficult temperament. Results: Parental perception of difficult temperament in the cohort was 7.3% (n = 492). Findings of the multivariable logistic regression showed that screen time >2 hours a day (AOR 2.43, 95% CI: 1.2, 4.9), child not being read to (AOR 3.92, 95% CI: 1.8, 8.5), and family history of mental health problems (AOR 2.69, 95% CI: 1.1, 6.5) significantly increased the odds of having a difficult temperament. Conclusion: Toddlers with difficult temperament were less likely to have received stimulatory experiences, and their families were more likely to be under greater stress. The findings emphasize the importance of parental support and anticipatory guidance in promoting nurturing care to facilitate child health and development, particularly in disadvantaged communities.

Coding of Childhood Psychiatric and Neurodevelopmental Disorders in Electronic Health Records of a Large Integrated Health Care System: Validation Study.

Background: Mental, emotional, and behavioral disorders are chronic pediatric conditions, and their prevalence has been on the rise over recent decades. Affected children have long-term health sequelae and a decline in health-related quality of life. Due to the lack of a validated database for pharmacoepidemiological research on selected mental, emotional, and behavioral disorders, there is uncertainty in their reported prevalence in the literature. objectives: We aimed to evaluate the accuracy of coding related to pediatric mental, emotional, and behavioral disorders in a large integrated health care system's electronic health records (EHRs) and compare the coding quality before and after the implementation of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) coding as well as before and after the COVID-19 pandemic. Methods: Medical records of 1200 member children aged 2-17 years with at least 1 clinical visit before the COVID-19 pandemic (January 1, 2012, to December 31, 2014, the ICD-9-CM coding period; and January 1, 2017, to December 31, 2019, the ICD-10-CM coding period) and after the COVID-19 pandemic (January 1, 2021, to December 31, 2022) were selected with stratified random sampling from EHRs for chart review. Two trained research associates reviewed the EHRs for all potential cases of autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD), major depression disorder (MDD), anxiety disorder (AD), and disruptive behavior disorders (DBD) in children during the study period. Children were considered cases only if there was a mention of any one of the conditions (yes for diagnosis) in the electronic chart during the corresponding time period. The validity of diagnosis codes was evaluated by directly comparing them with the gold standard of chart abstraction using sensitivity, specificity, positive predictive value, negative predictive value, the summary statistics of the F-score, and Youden J statistic. κ statistic for interrater reliability among the 2 abstractors was calculated. Results: The overall agreement between the identification of mental, behavioral, and emotional conditions using diagnosis codes compared to medical record abstraction was strong and similar across the ICD-9-CM and ICD-10-CM coding periods as well as during the prepandemic and pandemic time periods. The performance of AD coding, while strong, was relatively lower compared to the other conditions. The weighted sensitivity, specificity, positive predictive value, and negative predictive value for each of the 5 conditions were as follows: 100%, 100%, 99.2%, and 100%, respectively, for ASD; 100%, 99.9%, 99.2%, and 100%, respectively, for ADHD; 100%, 100%, 100%, and 100%, respectively for DBD; 87.7%, 100%, 100%, and 99.2%, respectively, for AD; and 100%, 100%, 99.2%, and 100%, respectively, for MDD. The F-score and Youden J statistic ranged between 87.7% and 100%. The overall agreement between abstractors was almost perfect (κ=95%). Conclusions: Diagnostic codes are quite reliable for identifying selected childhood mental, behavioral, and emotional conditions. The findings remained similar during the pandemic and after the implementation of the ICD-10-CM coding in the EHR system.

Social-emotional and behavioural problems in young children of healthcare worker mothers during the COVID-19 outbreak: a case-control study.

BACKGROUND: The pandemic has had a significant impact on the daily lives of children and their families, particularly the children of health care workers, due to changes in family routines as a result of their parents' work schedules. We aimed to explore the socioemotional and behavioural (SEB) problems of children of healthcare worker mothers (HCWM) during the COVID-19 pandemic and compare them with age-matched children and their mothers from other occupations. METHOD: A case-control study design was applied, and a snowball approach was used to enrol volunteered participants aged between 6 and 36 months of age, through a Google survey. We used the Brief Infant-Toddler Social and Emotional Assessment (BITSEA) questionnaire to assess children's SEB problems and a Brief Symptom Inventory (BSI) to evaluate the psychological distress of mothers. Differences in BITSEA, BSI and MSPSS scores were examined using chi-square and Mann-Whitney U tests, as appropriate. A logistic regression model was used to identify independent predictors of children's behavioural and emotional problems. RESULTS: In total, 600 questionnaires were analysed. It was observed that children in the HCWM group were separated from their mothers more often and for longer periods of time than their counterparts (p < 0.010, p = 0.002). Changes in the child's structured outdoor activities during the pandemic period were more likely to be observed in the HCWM group (p < 0.05). The percentage of children with the BITSEA problem subscale above the subclinical cut-off, externalizing and dysregulation scores were significantly higher in the HCWM group (p = 0.044, p = 0.031, and p = 0.016). Moreover, each point increase in BSI global index scores (p < 0.001, RR:3.34, 95%CI:1.91-5.82) was found as a risk factor for clinically significant SEB problems. CONCLUSION: Overall, the current study suggests HCWM's have experienced occupational inequality, and young children of HCWM's were at increased risk for externalizing and dysregulation problems during the pandemic. Maternal psychological stress had a significant impact on their children's socio-emotional well-being.
