Relationships Between Schistosoma mansoni Infection Intensity and Nutritional Status and Anemia Among Preschool-aged Children in Uganda.

In a cross-sectional analysis of 354 Ugandan children (age 12-48 months) infected with Schistosoma mansoni, we assessed relationships between infection intensity and nutritional morbidities. Higher intensity was associated with an increased risk for anemia (RR = 1.05, 95% confidence interval [CI] 1.01-1.10) yet not associated with risk for underweight, stunting, or wasting.

Prevalence of intestinal parasitism in preschool and school children in Colombia: Systematic review and meta-analysis.

OBJECTIVE: Intestinal parasitic infections (IPIs) are a public health challenge in developing countries such as Colombia, causing anaemia and delayed growth and development in children. We aimed to estimate the geographical and prevalence trend of IPIs in the last 30 years in school and preschool children in Colombia. METHODS: We conducted a systematic review and meta-analysis. We identified potential manuscripts through PubMed, EMBASE, Web of Science, LILACS, Scielo and Google Scholar on the IPIs prevalence in school and preschool children in Colombia. Articles included in the qualitative analysis were published between 1990 and 2020 in English or Spanish and met the inclusion criteria. Subsequently, a random-effects meta-analysis, a meta-regression and a trend analysis were performed. RESULTS: We identified 2292 articles; 109 were included in the qualitative review, and 79 articles were included in the meta-analysis. The estimated IPI prevalence was 55% (95% CI: 48-63). By age group, the prevalence in preschool children was 37% (95% CI: 26-49) and 66% (95% CI: 52-78) in schoolchildren. The prevalence by region was heterogeneous, with the Amazon being the highest (69%) and the Santanderes the lowest (28%). In the last 20 years, the prevalence of helminthiasis has decreased (from 64.66% in 1990-1995 to 22.09% in 2016-2020). CONCLUSION: The prevalence of IPIs is high (>30%) in three of the seven regions in Colombia. Biannual administration of mass deworming in schoolchildren is recommended in the Amazon region. Public policies aiming to control IPIs should be reinforced. Further prevalence studies should include Cesar, Guaviare, Vichada and Vaupés, where the epidemiology of IPIs is unknown. SUSTAINABLE DEVELOPMENT GOALS: Good health and wellbeing, clean water and sanitation, sustainable cities and communities.

Relationship between oral health literacy of caregivers and the oral health-related quality of life of children: a cross-sectional study.

BACKGROUND: Oral health literacy is the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate oral health decisions. However, scientific evidence about the oral health literacy of caregivers and the children's oral health-related quality of life. The purpose of this study was to verify the relationship between the level of oral health literacy of caregivers and the children's oral health-related quality of life (OHRQOL). METHODS: This study was conducted with children aged 2 to 4 in Diadema, São Paulo, Brazil. Six hundred thirty children were examined to assess the prevalence of dental caries (dmft index). Parents were interviewed to obtain sociodemographic status, oral conditions, and oral health literacy (OHL). The variable outcome was the children's OHRQOL as assessed by the Early Childhood Oral Health Impact Scale (ECOHIS). We fitted zero-inflated negative binomial regression (ZINB) models to evaluate associations between the study outcome and covariates in terms of PR (Prevalence Ratios), RR (Rate Ratios), and their respective Confidence Intervals (95% CI). RESULTS: Children's OHRQOL was not associated with OHL. Dental caries had a negative impact on the children's quality of life (p < 0.05). A reduced impact on OHRQOL is also associated with having siblings (PR = 0.70, 95% CI 0.52-0.95). A higher age of the mother reduced OHRQOL impacts (PR = 0.72, 95% CI 0.52-0.98). CONCLUSIONS: The factors associated with children's OHRQOL were the number of siblings, the mothers' age, and dental caries. This study observed no association between parental OHL and children's OHRQOL.

Persistence of anaemia among Samoan preschool age children: a longitudinal study.

OBJECTIVE: To characterise the prevalence and persistence of anaemia among Samoan children over a 2-3-year period. DESIGN: Data were from two consecutive waves (2015 and 2017-2018) of the Ola Tuputupua'e 'Growing up' study. Anaemia (Hb < 11·0 or 11·5 g/dl for 2-4 and ≥ 5 years old, respectively) was considered 'transient' when it occurred at only one wave or 'persistent' if it was present at two consecutive waves. Child, maternal and household correlates of anaemia were examined using log-binomial and modified Poisson regressions. SETTING: Eleven Samoan villages. PARTICIPANTS: Mother-child pairs (n 257) recruited in 2015 and reassessed in 2017-2018. RESULTS: Anaemia prevalence was 33·9 % in 2015 and 28·0 % in 2017-2018; 35·6 % of cases identified in 2015 were persistent. Risk of anaemia at only one wave was lower among children who were older in 2015 (age 4 v. 2 years, adjusted relative risk (aRR) = 0·54, (95 % CI 0·35, 0·84), P = 0·007), had older mothers (≥ 40 v. 18-29 years, aRR = 0·61, (95 % CI 0·39, 0·95), P = 0·029) and had higher daily sodium intake (for every 100 mg/d, aRR = 0·97, (95 % CI 0·95, 0·99), P = 0·003) than children with no anaemia. Children whose anaemia persisted were more likely to have had a mother with anaemia (aRR = 2·13, (95 % CI 1·17, 3·89), P = 0·013) and had higher daily dietary iron intake (for every 10 mg/d, aRR = 4·69, (95 % CI 1·33, 16·49), P = 0·016) than those with no anaemia. CONCLUSIONS: Alongside broadly targeted prevention efforts, which are warranted given the moderate-high anaemia prevalence observed, specific attention should be paid to children with risk factors for persistent anaemia. Routine screening of children whose mothers have anaemia should be encouraged.

Time trend of axial length and associated factors in 4- and 5-year-old children in Shanghai from 2013 to 2019.

PURPOSE: To evaluate the time trend of axial length (AL) and associated factors in 4- and 5-year-old children in Shanghai from 2013 to 2019. METHODS: This was a 7-year observational study of 985 four-year-old and 1059 five-year-old children in Shanghai. AL, horizontal and vertical corneal curvature, spherical equivalent (SE), and body height and weight were measured. Furthermore, a questionnaire was collected, including time outdoors and bad eyesight habits. RESULTS: In 4-year-old children, no significant difference was found in AL (P = 0.526), but significant differences were observed in SE (P = 0.001), horizontal corneal curvature (P = 0.006), vertical corneal curvature (P = 0.004), height (P < 0.001), and weight (P = 0.022) from 2013 to 2019. In 5-year-old children, no significant differences were found in AL (P = 0.304), SE (P = 0.200), or weight (P = 0.292), but significant differences were observed in horizontal corneal curvature (P = 0.040), vertical corneal curvature (P = 0.015), and height (P < 0.001) from 2013 to 2019. Multivariate analyses revealed that AL was mainly significantly associated with boys and time outdoors in the 4- and 5-year-old children. CONCLUSIONS: The AL of 4- and 5-year-old children remained relatively stable in Shanghai from 2013 to 2019. Longitudinal studies are needed to confirm the relationship between AL elongation and environmental risk factors.

Residential pyrethroid insecticide use, urinary 3-phenoxybenzoic acid levels, and attention-deficit/hyperactivity disorder-like symptoms in preschool-age children: The Environment and Development of Children study.

Previous animal studies have reported that pyrethroids can cause dopamine system abnormalities and attention-deficit/hyperactivity disorder (ADHD) phenotypes. However, epidemiological studies investigating the associations between pyrethroid exposure and ADHD are limited. We aimed to investigate the association between pyrethroid exposure and ADHD-like symptoms among preschool-age children. We used data from 385 children at 4 years of age participating in the Environment and Development of Children (EDC) study. We evaluated pyrethroid exposure through questionnaires and urinary 3-phenoxybenzoic acid (3-PBA) concentrations. We assessed ADHD-like symptoms using the Korean ADHD rating scale (K-ARS). We conducted negative binomial regressions to evaluate the associations between pyrethroid exposure and ADHD-like symptoms. Residential use of insecticide adhesive (ß = 0.42, 95% CI: 0.11, 0.74) and insecticide spray (ß = 0.33, 95% CI: 0.08, 0.59) was associated with an increase in log-transformed creatinine-adjusted urinary 3-PBA concentrations. Residential insecticide adhesive use was associated with a 51.6% increase in K-ARS scores (95% confidence interval [CI]: 6.3, 116.1) among boys, when compared with non-users. When compared with creatinine-adjusted 3-PBA levels <0.50 µg/g creatinine, creatinine-adjusted 3-PBA levels ≥3.80 µg/g creatinine were associated with a 58% increase in K-ARS scores (95% CI: 0.1, 150.5) among boys. We found associations of residential pyrethroid insecticide use and urinary 3-PBA concentrations with K-ARS scores among preschool-age boys. Since the present study explored cross-sectional associations in preschool-age children, the possibility of reverse causality cannot be dismissed. Further studies implementing a cohort study design are warranted.

Epidemiology of intestinal parasitic infections in preschool and school-aged Ethiopian children: a systematic review and meta-analysis.

BACKGROUND: Numerous studies have been carried out on assessing the prevalence of intestinal parasites infections (IPIs) amongpreschool and school-age children in Ethiopia, but there is lack of study systematically gathered and analyzedinformation for policymakers. Therefore, the aim of this systematic review and meta-analysis was to provide a summary on prevalence, geographical distribution and trends of IPIs among preschool and school-age childrenin Ethiopia. METHODS: The search were carried out in Medline via PubMed, Scopus, Science Direct, Web of Science, and Google Scholar from 1996to July2019 for studies describing prevalence of IPIs among preschooland school-age children. We conducted meta-regression to understand the trends and the source of heterogeneity and pooled the prevalence using 'metaprop' command using STATA software version 14. RESULTS: Eighty-three(83) studies examining 56,786 fecal specimens were included. The prevalence of IPIs was 48%(95%CI: 42 to 53%) and showedsignificantly decreasing trends 17% (95% CI: 2.5 to 32%) for each consecutive 6 years) and was similar in males and females. The pooled prevalence in years 1997-2002, 2003-2008, 2009-2014 and > 2014 was 71% (95% CI: 57 to 86%), 42% (95% CI: 27 to 56%), 48% (95% CI: 40 to 56%) and 42% (95% CI: 34 to 49%), respectively. Poly-parasitism was observed in 16% (95% CI: 13 to 19%,) of the cases. CONCLUSION: Intestinal parasite infections are highly prevalent among preschool and school-age children and well distributed across the regional states of Ethiopia. Southern and Amhara regional states carry the highest burden. We observed significant decreasing trends in prevalence of IPIs among preschool and school-ageEthiopian children over the last two decades. Therefore, this study is important to locate the geographical distribution and identified high risk areas that should be prioritized further interventions, which complement global efforts towards elimination of IPIs infections by 2020.

Longitudinal Trends in the Diagnosis of Attention-Deficit/Hyperactivity Disorder and Stimulant Use in Preschool Children on Medicaid.

OBJECTIVES: To describe trends in the diagnosis of attention-deficit/hyperactivity disorder (ADHD) and prescribing of stimulants in preschool-age children receiving Medicaid and to identify factors associated with the receipt of psychosocial care. STUDY DESIGN: Data were extracted from 2012-2016 Kentucky Medicaid claims for children aged <6 years. ADHD was identified using International Classification of Diseases, Tenth Revision codes F90.0, F90.1, F90.2, F90.8, and F90.9. Psychosocial therapy was defined as having at least 1 relevant Current Procedural Terminology code in a claim within the year. A generalized linear model with a logit link and binomial distribution was used to assess factors associated with receipt of psychosocial treatment in 2016. RESULTS: More than 2500 (1.24%) preschool-aged children receiving Medicaid had a diagnosis of ADHD in 2016, with 988 (38.2%) of those receiving a stimulant medication. Children in foster care were diagnosed with and/or treated for ADHD 4 times more often than other Medicaid recipients. Of the 1091 preschoolers receiving stimulants, 99 (9%) did not have a diagnosis of ADHD. There were no significant differences in diagnoses by race/ethnicity, but children reported to be black, Hispanic, or other race/ethnicity received stimulants at a lower rate than white children. Positive predictors for receiving psychosocial therapy in 2016 included having the diagnosis but not receiving a stimulant, having at least 1 prescription written by a psychiatrist, having comorbidities, and age. The use of stimulants in children aged <6 years declined from 0.9% in 2012 to 0.5% in 2016. CONCLUSIONS: Promising trends demonstrate a decreasing use of stimulants in preschoolers; however, continued vigilance is needed to promote the optimal use of psychosocial interventions.

Visual Acuity Assessment and Vision Screening Using a Novel Smartphone Application.

OBJECTIVES: To evaluate a smartphone-based application's (Peek Acuity) ability to assess visual acuity and screen for ocular conditions in children, we compared visual acuity assessment between Peek Acuity and the pediatric ophthalmology examination and evaluated Peek Acuity's ability to identify children with referable ocular conditions. STUDY DESIGN: We prospectively recruited 111 children age 3-17 years, presenting to a pediatric ophthalmology clinic, who could follow instructions. Monocular visual acuity assessments by Peek Acuity and standard clinical methods were performed in randomized order. We compared visual acuity assessments between methods using intraclass correlation coefficient (ICC) and evaluated Peek Acuity's ability to identify children with referable ocular conditions. RESULTS: ICC comparing visual acuity assessed between methods was 0.88 (95% CI 0.83-0.92) for first and 0.85 (95% CI 0.78-0.89) for second eyes examined. ICC among 3 to 5-year-olds (preschool-age children) was 0.88 (95% CI 0.77-0.94) for first and 0.45 (95% CI 0.13-0.68) for second eyes examined. Peek Acuity had a sensitivity of 83%-86% for decreased vision and 69%-83% for referable ocular disease. Sensitivity was highest among 3 to 5-year-olds with decreased vision, 93%-100%. CONCLUSIONS: Overall, Peek Acuity visual acuity assessment correlated well with visual acuity assessed by standard clinical methods, though preschool-age children appeared more susceptible to examination fatigue. Peek Acuity performed adequately as a screening tool and had the greatest sensitivity among those with decreased vision and preschool-age children. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03212222.

The effects of supplementing maternal and infant diets with lipid-based nutrient supplements on physical activity and sedentary behaviour at preschool age in Ghana.

Evidence on whether nutritional supplementation affects physical activity (PA) during early childhood is limited. We examined the long-term effects of lipid-based nutrient supplements (LNS) on total PA, moderate-to-vigorous PA (MVPA) and sedentary behaviour (SB) of children at 4-6 years using an accelerometer for 1 week. Their mothers were enrolled in the International Lipid-based Nutrient Supplement-DYAD randomised controlled trial in Ghana, assigned to daily LNS or multiple micronutrients (MMN) during pregnancy through 6 months postpartum or Fe and folic acid (IFA) during pregnancy and placebo for 6 months postpartum. From 6 to 18 months, children in the LNS group received LNS; the other two groups received no supplements. Analysis was done with intention to treat comparing two groups: LNS v. non-LNS (MMN+ IFA). Of the sub-sample of 375 children fitted with accelerometers, 353 provided sufficient data. Median vector magnitude (VM) count was 1374 (interquartile range (IQR) 309), and percentages of time in MVPA and SB were 4·8 (IQR 2) and 31 (IQR 8) %, respectively. The LNS group (n 129) had lower VM (difference in mean -73 (95 % CI -20, -126), P = 0·007) and spent more time in SB (LNS v. non-LNS: 32·3 v. 30·5 %, P = 0·020) than the non-LNS group (n 224) but did not differ in MVPA (4·4 v. 4·7 %, P = 0·198). Contrary to expectations, provision of LNS in early life slightly reduced the total PA and increased the time in SB but did not affect time in MVPA. Given reduced social-emotional difficulties in the LNS group previously reported, including hyperactivity, one possible explanation is less restless movement in the LNS group.

The effect of content and tone of maternal evaluative feedback on self-cognitions and affect in young children.

Feedback that young children receive from others can affect their emotions and emerging self-views. The current experiment tested the effect of negative content (criticism) and negative tone (hostile) of the feedback on children's affect, self-evaluations, and attributions. We also explored whether maternal history of depression and children's temperament moderated these relations. Participants were 152 mothers and children (48% girls) aged 4 and 5 years (M = 61.6 months, SD = 6.83). The task involved three scenarios enacted by dolls; a child doll made something (e.g., picture, house, numbers) that had a mistake (e.g., no windows on the house) and proudly showed it to the mother doll, who then gave feedback (standardized, audio recorded) to the child. Children were randomized to one of four maternal feedback conditions: negative or neutral content in either a negative or neutral tone. Negative content (criticism) produced significantly more negative affect and lower self-evaluations than neutral content. When the tone of the feedback was hostile, children of mothers who had been depressed during the children's lifetimes were significantly more likely to make internal attributions for mistakes than children of nondepressed mothers. In addition, among children with low temperamental negative affectivity, in the presence of negative tone, negative content significantly predicted more internal attributions for the errors. Findings are discussed in terms of understanding the role of evaluative feedback in children's emerging social cognitions and affect.

Assessing and quantifying the secure base script from narratives produced by preschool age children: justification and validation tests.

Building on aframework presented by Bretherton and associates, Waters and associates argued that interaction sequences relevant to children's access to and use of asecure base for exploration during infancy/toddlerhood become internalized as script-like representations. For adults, these scripted representations are readily assessed using word-prompt lists d to elicit attachment relevant narratives. However, this method is not appropriate during early childhood. Waters and associates used stories from Bretherton's Attachment Story Completion Task for this purpose. However, the method they used to score secure base script use is not efficient for larger samples (e.g. over 50), and new approaches for scoring have been designed. We describe two approaches to story selection and scoring for access to and use of the secure base script. The two scoring methods show substantial and significant overlap and also have significant associations with other methods of measuring attachment security during early childhood.

A qualitative study of the multi-level influences on oral hygiene practices for young children in an Early Head Start program.

BACKGROUND: Individual child-level risk factors for Early Childhood Caries (ECC) have been studied, but broader family- and community-level influences on child oral hygiene behaviors are less well understood. This study explored multiple levels of influence on oral hygiene behaviors for young children in Early Head Start (EHS) to inform a future behavioral intervention targeting children from low-income families. METHODS: Twenty-four semi-structured interviews were conducted with mothers of children under 4 years old, enrolled in the home visitor (HV) component of one EHS program in Los Angeles, CA, who participated in the BEhavioral EConomics for Oral health iNnovation pilot study (BEECON) in 2016-7. Audio-recordings of interviews were translated if needed, and transcribed in English, and coding and analysis was facilitated by Dedoose qualitative software. This investigation used general thematic analysis guided by the Fisher-Owens child oral health conceptual framework to identify influences on oral hygiene behaviors for the young children. RESULTS: Many mothers reported brushing their children's teeth twice/day, and concern that most children frequently resisted brushing. They identified children being sick or tired/asleep after outings as times when brushing was skipped. Several child-, family-, and community-level themes were identified as influences on child oral hygiene behaviors. At the child-level, the child's developmental stage and desire for independence was perceived as a negative influence. Family-level influences included the mother's own oral hygiene behaviors, other family role models, the mother's knowledge and attitudes about child oral health, and mothers' coping skills and strategies for overcoming challenges with brushing her child's teeth. Overall, mothers in the EHS-HV program were highly knowledgeable about ECC risk factors, including the roles of bacteria and sugar consumption, which motivated regular hygiene behavior. At the community-level, mothers discussed opportunities to connect with other EHS-HV families during parent meetings and playgroups that HV coordinated. A few mothers noted that EHS-HV playgroups included brushing children's teeth after snacking, which can be a potential positive influence on children's hygiene practices. CONCLUSION: Child-, family- and community-level factors are important to consider to inform the development of tailored oral health preventive care programs for families in EHS-HV programs.

Associations between prenatal substance exposure, prenatal violence victimization, unintended pregnancy, and trauma exposure in childhood in a clinical setting.

Given the importance of early prevention and intervention strategies for children exposed to trauma, detection of early risk factors for exposure to traumatic events in childhood is critical. The present study examined associations between three known prenatal risk factors that characterize environmental instability in utero-prenatal substance exposure, prenatal violence victimization, and unintended pregnancy-and child exposure to interparental violence and other adverse experiences in a sample of 198 mother-child dyads (M child age = 44.48 months) referred to a hospital clinic for treatment following exposure to trauma. Prenatal substance and violence exposure were associated with child trauma exposure, and prenatal violence victimization was also associated with maternal severity ratings of traumatic exposures. Unintended pregnancy was not associated with child trauma exposure or severity. These findings expand our understanding of prenatal risk factors for trauma exposure in childhood and, specifically, highlight prenatal substance exposure and violence victimization as risk factors for subsequent exposure to trauma in early childhood. Results suggest that prenatal prevention and intervention programs should target reducing maternal substance use and in-utero exposure to violence.

Dada la importancia de las estrategias de prevención e intervención tempranas para niños expuestos al trauma, el detectar los tempranos factores de riesgo en el caso de estar expuesto a eventos traumáticos en la niñez es crítico. El presente estudio examinó las asociaciones entre tres conocidos factores de riesgo prenatales que caracterizan la inestabilidad ambiental en el útero -el haber estado expuesto a sustancias prenatalmente, la victimización de la violencia prenatal, y el embarazo no intencional -y el que el niño esté expuesto a la violencia entre progenitores (IPV) y otras experiencias adversas en un grupo muestra de 198 díadas madre-niño (edad promedio del niño = 44.48 meses) que habían sido referidas a una clínica hospital para el tratamiento que seguía al haber estado expuestos al trauma. El haber estado expuesto a sustancia y violencia prenatal se asoció con el hecho de que el niño había estado expuesto a trauma, y la victimización de la violencia prenatal también se asoció con la severidad maternal de clasificación de la exposición traumática. El embarazo no intencional no se asoció con la exposición del niño al trauma o la severidad. Estos resultados amplían nuestra comprensión de los factores de riesgo prenatales en cuanto al haber estado expuesto al trauma en la niñez y, específicamente, subrayan el haber estado expuesto a sustancias prenatalmente y la victimización de la violencia como subsecuentes factores de riesgo para estar expuesto al trauma en la temprana niñez. Los resultados sugieren que los programas de prevención e intervención prenatales deber enfocarse en reducir el uso de sustancias por parte de la madre y el estar expuesto dentro del útero a la violencia.

Vu l'importance des stratégies de prévention précoce et d'intervention pour les enfants exposés au trauma, la détection de facteurs de risque précoce pour l'exposition à des événements traumatiques s'avère critique. Cette étude a examiné les liens entre trois facteurs de risque prénatals connus qui caractérisent l'instabilité environnementale in utero - l'exposition prénatale à des substances toxiques, la victimisation liée à la violence prénatale, et la grossesse involontaire - ainsi que l'exposition à la violence conjugale et d'autres expériences adverses chez un échantillon de 198 dyades mère-enfant (moyenne d'âge de l'enfant = 44,48 mois) envoyées consulter en clinique hospitalière pour un traitement suivant une exposition à un trauma. L'exposition à la toxicomanie et l'exposition à la violence étaient liées à l'exposition de l'enfant au trauma et la victimisation liée à la violence prénatale était également liée à la sévérité des scores maternels d'expositions traumatiques. La grossesse involontaire n'était pas liée à l'exposition au trauma de l'enfant ou à la sévérité. Ces résultats élargissent notre compréhension des facteurs prénatals d'exposition au trauma dans l'enfance et mettent en lumière plus spécifiquement l'exposition à la toxicomanie prénatale et la victimisation liée à la violence en tant que facteurs de risque d'exposition ultérieure au trauma durant la petite enfance. Les résultats suggèrent que la prévention prénatale et les programmes d'intervention devraient cibler la réduction d'utilisation toxicomane maternelle et l'exposition à la violence in-utero.

Prevalence, intensity and factors associated with soil-transmitted helminths infections among preschool-age children in Hoima district, rural western Uganda.

BACKGROUND: Over 80% of morbidity due to soil-transmitted helminthiasis (STH) occurs in low-income countries. Children under 5 account for 20-30% of the burden in endemic areas. This study assessed the prevalence, intensity and factors associated with STH infections among preschool-age children (PSAC) in Hoima district, Uganda. The PSAC are particularly vulnerable because the chronicity of this condition usually affects their physical and mental growth and development. METHODS: A cross-sectional study was carried out among 562 PSAC (1-5 years old) in 6 counties of Hoima district using Expanded Program on Immunization (EPI) method. Stool samples from children were examined using the formol ether concentration technique for STH egg detection. Egg counts were represented as egg per gram (EPG). A structured questionnaire was used to collect information on factors associated with STH infection. Generalized linear models were used to analyze relationships between STH infection and associated factors. RESULTS: Overall STH prevalence was 26.5%. Hookworm infection was the most prevalent (18.5%), followed by A.lumbricoides (9.8%) and T.trichiura (0.5%). Prevalence of STH infection was significantly higher in children aged 5 years (Pearson chi-square test, p = 0.009) than in children aged 1 year. The general geometric mean (GM) counts for Hookworm infection was (696.1 EPG; range (530.3-913.8)) with girls having a higher GM (789.8 EPG; range (120-13,200)) than boys. Eating uncooked or unwashed vegetables (adj. Prevalence Ratio (PR) = 1.9, 95% CI: 1.3-2.7) and fruits (adj.PR = 1.8, 95% CI: 1.1-2.8), indiscriminate disposal of young children's faeces (adj.PR = 1.5, 95% CI: 1.1-2.0); not washing hands after defecation (adj.PR = 2.6, 95% CI: 1.9-3.6); and not deworming children regularly (adj.PR = 1.4, 95% CI: 1.1-1.8) were significantly associated with STH infection. CONCLUSION: The prevalence of Soil transmitted helminths infection among preschool-age children in Hoima district significantly increased with age. Poor hygiene, inadequate sanitation and irregular deworming were associated with STH infections among PSAC in the study area. Intense health education on the importance of hygienic practices, improved sanitation and regular deworming of PSAC should be integrated into prevention and control programs.

Iodine Status and Its Influencing Factors in Hospitalized and Healthy Preschool-Age Children.

Iodine is a trace element necessary for synthesizing thyroid hormones. It is especially crucial for the neurodevelopment and intellectual development of children. Preschool-age children admitted to the hospital tend to have more fragile physical and mental health, but few studies demonstrate their iodine status. Our study aimed to investigate the iodine status of hospitalized and healthy preschool-age children and to explore the factors influencing them. From January to December 2021, 426 children aged 3-6 years were admitted to the respiratory department for pneumonia, bronchopneumonia, or bronchiectasis, but they could eat normally and were recruited as hospitalized children. Six hundred ten healthy children aged 3-6 years were included. We collected anthropometric measurements and urine samples from hospitalized and healthy preschool-age children, and iodine status was assessed through urinary iodine concentration (UIC) and urinary iodine/creatinine ratio (UI/Cr). UIC was 40.1 and 166.1 µg/L for hospitalized and healthy preschool-age children, respectively (P < 0.001). Urinary creatinine concentration (UCr) was 0.2 and 0.8 g/L for hospitalized and healthy preschool-age children, respectively (P < 0.001). UIC decreased with increasing height z-scores in hospitalized children (Spearman's rho = -0.11, P = 0.022). A significantly increased risk of UIC < 100 µg/L was found in hospitalized children (OR = 9.1 (6.8, 12.2), P < 0.001) when compared to healthy children. In conclusion, hospitalized preschool-age children are likelier to have iodine insufficiency than healthy preschool-age children, especially those with good linear growth. Measures should be implemented to ensure adequate iodine intake of preschool-age children during hospitalization to avoid affecting their intellectual and physical development. Due to lower UCr in hospitalized children, creatinine is not appropriate for assessing iodine status in hospitalized children.

Clinical vitamin A deficiency among preschool aged children in southwest Ethiopia.

Background: The clinical manifestations of vitamin A deficiency (VAD) involve night blindness, bitot's spots, corneal xerosis, and corneal scars. It is the most important cause of preventable childhood blindness among children and causes morbidity and mortality. Even though Ethiopia implemented high-potency vitamin A supplements, the occurrence of VAD remains significant. This study was to identify determinants of clinical VAD among preschool-aged children (PSC) in southwest Ethiopia. Method: A community-based survey was conducted among 411 randomly selected PSCs. A pretested and structured questionnaire coupled with clinical observation for signs of vitamin A deficiency by a trained ophthalmologist was used to collect the data. An anthropometric measurement of height was taken and analyzed using WHO Anthro to calculate Z-scores for each index. The public health significance of VAD was declared after comparison with international references. A bi-variable and multi-variable logistic analysis was done. We reported the adjusted odds ratio (AOR), 95% confidence interval, and p-value. Result: A total of 411 children were screened for clinical VAD, and the overall prevalence was 2.2% (95% CI: 1.5-2.5). Of which, night blindness affects 1.2%, bitot's spots affects 0.7%, and corneal xerosis affects 0.2%, indicating a major public health problem compared to the international reference. The odds of clinical VAD were 81% lower among children who received vitamin A supplementation (VAS; AOR = 0.19, 95% CI: 0.04-0.92). On the other hand, PSC of mothers who had attended ANC visits were 89% less likely to develop clinical VAD (AOR = 0.11, 95% CI: 0.02-0.53). In addition, the study revealed that the odds of developing clinical VAD are 82% lower among PSC aged 36 to 47 months (AOR = 0.18; 95% CI: 0.03-0.97). Conclusion: The prevalence of clinical VAD among PSC is a public health problem and is associated with ANC visits, VAS status, and the age of the child, which could be used to target interventions to further reduce existing VAD. Further studies using reliable dietary intake and biomarker data could further depict the burden of subclinical VAD.

The Longitudinal Relation Between Academic/Cognitive Skills and Externalizing Behavior Problems in Preschool Children.

OBJECTIVE: Existing research suggests that there is a relation between academic/cognitive deficits and externalizing behavior in young children, but the direction of this relation is unclear. The present study tested competing models of the relation between academic/cognitive functioning and behavior problems during early childhood. METHOD: Participants were 221 children (120 boys, 101 girls) who participated in a longitudinal study from age 3 to 6. RESULTS: A reciprocal relation (Model 3) was observed only between inattention and academic achievement; this relation remained controlling for SES and family stress. The relation between inattention and cognitive ability was consistent with Model 1 (cognitive skills predicting later inattention) with controls. For hyperactivity and aggression, there was some support for Model 2 (early behavior predicting later academic/cognitive ability), but this model was no longer supported when controlling for family functioning. CONCLUSION: These results suggest that the relation between academic achievement/cognitive ability and externalizing problems may be driven primarily by inattention. These results also suggest that this relation is evident early in development, highlighting the need for early assessment and intervention.

Social Challenges as a Consequence of the COVID-19 Pandemic among South Florida Preschool Children with Disability and Obesity.

The COVID-19 pandemic has negatively impacted the childcare industry over the past two years. This study examined how pandemic-related challenges impacted preschool-aged children by disability and obesity status. Participants were 216 children (80% Hispanic, 14% non-Hispanic Black) aged 2 to 5 years in 10 South Florida childcare centers. In November/December 2021, parents completed a COVID-19 Risk and Resiliency Questionnaire, and body mass index percentile (BMI) was collected. Multivariable logistic regression models examined the association of COVID-19 pandemic-related social challenges (transportation, employment) and child BMI and disability status. As compared to normal-weight children, those families with a child who was obese were more likely to report pandemic-related transportation (OR: 2.51, 95% CI: 1.03-6.28) challenges and food insecurity (OR: 2.56, 95% CI: 1.05-6.43). Parents of children with disabilities were less likely to report that food did not last (OR: 0.19, 95% CI: 0.07-0.48) and that they could not afford balanced meals (OR: 0.33, 95% CI: 0.13-0.85). Spanish-speaking caregivers were more likely to have a child who was obese (OR: 3.04, 95% CI: 1.19-8.52). The results suggest that COVID-19 impacts obese preschool children from Hispanic backgrounds, while disability was a protective factor.

Assessment of Vitamin D status and association with inflammation: Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project.

BACKGROUND: It is unclear whether 25(OH)D concentrations in children and female adults may be influenced by inflammation and thus require adjustment when estimating the population prevalence of vitamin D deficiency. OBJECTIVES: We examined correlations between inflammation biomarkers, CRP or alpha-1-acid glycoprotein (AGP), and serum 25(OH)D concentrations among preschool children (PSC; 6-59 mo) and nonpregnant females of reproductive age (FRA; 15-49 y). METHODS: We analyzed cross-sectional data from 6 nationally representative nutrition surveys (Afghanistan, Cambodia, Pakistan, UK, USA, and Vietnam) conducted among PSC (n = 9880) and FRA (n = 14,749) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia project. Rank correlations between CRP or AGP and 25(OH)D concentrations were examined while taking into account complex survey design effects. RESULTS: Among both PSC and FRA, correlations between inflammation and vitamin D biomarkers were weak and inconsistent across surveys. For PSC, correlation coefficients between CRP and 25(OH)D concentrations ranged from -0.04 to 0.08, and correlations between AGP and 25(OH)D ranged from 0.01 to 0.05. Correlation coefficients between CRP and 25(OH)D for FRA ranged from -0.11 to 0.14, and correlations between AGP and 25(OH)D concentrations ranged from -0.05 to 0.01. CONCLUSIONS: Based on the weak and inconsistent correlations between CRP or AGP and 25(OH)D, there is no rationale to adjust for these inflammation biomarkers when estimating population prevalence of vitamin D deficiency in PSC or FRA.
