RESUMO

AIM: Media use in children has exploded in the past several decades, most recently fuelled by portable electronic devices. This study aims to explore differences in functional brain connectivity in children during a story-listening functional MRI (fMRI) task using data collected before (1998) and after (2013) the widespread adoption of media. METHODS: Cross-sectional data were collected from English-speaking 5- to 7-year-old children at Cincinnati Children's Hospital Medical Center, USA, of a functional MRI narrative comprehension task completed in 1998 (n = 22) or 2013 (n = 25). Imaging data were processed using a graph theory approach, focusing on executive functions, language and visual processing networks supporting reading. RESULTS: Group differences suggest more efficient processing in the fronto-parietal network in the pre-media group while listening to stories. A modulation of the visual and fronto-parietal networks for the post-media exposure group was found. CONCLUSION: Further studies are needed to assess effects over time in the more exposed group to discern a causal effect of portable devices on cognitive networks.

RESUMO

BACKGROUND: The AAP recommends "shared" reading from early infancy for healthy development. However, many families are uncertain how to read most enjoyably and effectively with infants, especially from underserved backgrounds. Shared reading quality (interactivity) moderates benefits yet is challenging to measure. SHARE/STEP is a new model of shared reading quality at this age incorporating evidence-based behaviors. OBJECTIVE: To test the SharePR parent-report measure of caregiver-infant reading quality. METHODS: This study involved mother-infant dyads in two unrelated trials in an obstetric (0-2 months old) and pediatric (6-9 months old) clinic. SharePR is a 10-item measure based on the SHARE/STEP model. Analyses involved descriptive statistics, measures of psychometric integrity, and correlations with home literacy environment (HLE). RESULTS: There were 99 dyads in the younger (1.2 + 0.5 months) and 108 dyads in the older groups (6.6 + 1.1 months). A majority were of non-white race (73%, 96%) and low-socioeconomic status (56%, 44% in-poverty). SharePR administration time was under 2 min and scores were normally distributed at each age. Psychometric properties were strong in terms of internal consistency and reliability. Scores were positively correlated with HLE for the older group (p < 0.05). CONCLUSIONS: SharePR may be an efficient tool to quantify shared reading quality with infants, warranting further investigation. CLINICAL TRIALS: Data for these analyses were collected via two unrelated trials led by the lead author (J.S.H.). For the younger cohort, this is registered on the ClinicalTrials.gov website, ID# NCT04031235. For the older cohort, this is registered on the ClinicalTrials.gov website, ID# 2017-6856. IMPACT: The AAP recommends caregiver-child ("shared") reading beginning in infancy, yet many families are uncertain how to do so. Verbal and social-emotional interactivity during shared reading ("quality") moderates benefits and is often low in families from disadvantaged backgrounds, yet is challenging to measure. SharePR is a 10-item parent-report measure of shared reading quality based on a novel conceptual model incorporating evidence-based behaviors (SHARE/STEP). SharePR exhibited promising psychometric properties in two separate samples of mothers of younger and older infants. SharePR is a potentially useful measure of shared reading quality at this formative age, for research and to frame early reading guidance.

RESUMO

The expanded simple view of reading (SVR) model suggests that word decoding, language comprehension and executive functions are necessary for reading comprehension. Children with reading difficulties (RDs) often have deficits in critical components of reading established in the expanded SVR model and alterations in brain function of reading-related regions. Maternal education could provide children with advantageous educational opportunities or resources that support reading acquisition. The primary goal of this study was to examine the contributions of maternal education to the behavioural and neurobiological correlates of the expanded SVR model. Seventy-two 8- to 12-year-old children with RDs and typical readers (TRs) completed reading, behavioural and an functional magnetic resonance imaging stories-listening task to determine the functional connectivity of the receptive language network to the whole brain in association with maternal education. Higher maternal education was associated with better vocabulary in children with RDs and positive functional connectivity between the receptive language network and regions related to visual processing in children with RDs versus TRs. These data suggest that maternal education supports the ability to comprehend oral language and engagement of neural networks that support imagination/visualization in children with RDs.

RESUMO

Literacy is a major social determinant of health, rooted in skills that develop during early childhood. Children arriving at kindergarten unprepared to learn to read are more likely to have low reading proficiency thereafter. General and health literacy are highly correlated, affecting understanding of health conditions, treatment adherence, and transition to self-care and adult healthcare services. The American Academy of Pediatrics (AAP) recommends literacy and school readiness promotion during well-visits and neurodevelopmental surveillance is emphasized across primary and subspecialty care. While genetic and environmental risk factors for reading difficulties are well-established, risks related to complex and chronic medical conditions are less appreciated and under-researched. This review applies an eco-bio-developmental framework to explore literacy across five complex chronic conditions affecting millions of children worldwide: asthma, cancer, congenital heart disease, epilepsy, and sickle cell disease. In each, integration of an efficient reading brain network may be impacted by direct factors, such as ischemia, anesthesia, and/or medications, and also indirect factors, such as altered parent-child routines, hospital stays, and missed school. By integrating literacy into care management plans for affected children, pediatric primary care and specialty providers are poised to identify risks early, target guidance and interventions, and improve academic and health outcomes. IMPACT: While genetic and environmental risk factors for reading difficulties are well-established, risks related to complex and/or chronic medical conditions such as asthma, cancer, congenital heart disease, epilepsy, and sickle cell disease are substantial, less appreciated, and under-researched. General and health literacy are highly correlated, with implications for the understanding one's health condition, treatment adherence, and transitioning to self-care, which is especially important for children with complex and/or chronic illness. Pediatric primary care and specialty providers are poised to integrate reading and literacy into care management plans for children with complex and/or chronic illness, including early screening, guidance, support, and interventions.

RESUMO

AIM: Digital media use is prevalent among children and linked to potential developmental and health risks, but validated measures of children's digital media use are lacking. The aim of this study was to validate the Portuguese version of the ScreenQ with three distinct children's age groups. METHODS: Parents of children living in Portugal completed an online survey including the 16-item version of the ScreenQ and items related to home activities and digital media use. A combination of classical and modern theory (Rasch) methods was used for analysis. RESULTS: A total of 549 mothers and 51 fathers of 325 girls and 322 boys from 6 months to 9 years and 11 months old responded to the survey. Point-measure correlations were all positive and endorsement of item values were within acceptable ranges. Cronbach's coefficient α was acceptable for a new measure, and test-retest reliability was high. Statistically significant correlations were found between ScreenQ total scores and relevant demographic, play-related, parenting and digital media use items. CONCLUSION: The Portuguese version of the ScreenQ exhibited sound psychometric properties, including internal consistency and concurrent validity referenced to external items. Higher ScreenQ scores were correlated with higher digital media multitasking, lower parent-child interaction, and higher concerns regarding child's learning and behaviour.

RESUMO

OBJECTIVE: To assess whether a citywide structured book-sharing program (NICU Bookworms) designed to promote reading to infants while admitted in the neonatal intensive care unit (NICU) would increase parental reading behaviors (≥3-4 days/week) in the NICU and after discharge home, including high-risk parents who do not themselves enjoy reading. STUDY DESIGN: The NICU Bookworms program comprised staff training, parent education, and building a literacy-rich environment. In this quasi-experimental intervention study, parents of medically high-risk NICU graduates <6 months of age were administered a questionnaire at their first NICU follow-up clinic visit. The survey incorporated questions from the StimQ-I READ subscale to assess home reading environment and shared reading practices. RESULTS: A total of 317 infants were enrolled, 187 in an unexposed comparison group and 130 in the intervention group. Parents exposed to Bookworms were significantly more likely to read ≥3-4 days per week while in the NICU (34.5% vs 51.5%; P = .002; aOR, 2.2; 95% CI, 1.2-4.0), but reading at home did not differ (67.9% vs 73.1%; P = .28; aOR, 0.99; 95% CI, 0.5-1.8). However, among parents who did not themselves enjoy reading, frequency was significantly higher both in the NICU (18.4% vs 46.1%; P = .009; aOR, 5.0; 95% CI, 1.2-21.5) and at home (36.9% vs 70%; P = .003; aOR, 3.7; 95% CI, 1.1-12.9). A qualitative thematic analysis found that Bookworms decreased parental stress, enhanced bonding, and supported positive parent-infant interactions. CONCLUSIONS: A book-sharing intervention in the NICU increased parent-reported reading aloud during hospitalization and among parents disinclined to read for pleasure, both in the NICU and following discharge. This change may have been mediated by enhancement of parent-infant interactions.

RESUMO

INTRODUCTION: Maternal depression is characterized by a lack of emotional responsiveness and engagement with their child, which may lead to the child's decreased cognitive, and language outcomes all related to the child's future reading outcomes. The relations between maternal depression and functional connectivity in neural circuits supporting language in the child was explored. METHODS: Eleven 4-year-old girls completed language abilities assessment and resting-state functional magnetic resonance imaging scan. Their mothers completed the Beck's Depression Inventory (BDI) to examine maternal depression when the child was 12 months old and at the age of 4. Functional connections within the child's resting-state phonology, semantics, language networks were correlated with maternal BDI scores at the age of 4 years. RESULTS: Higher maternal depression was associated with the child's decreased within the semantic and phonological networks connectivity during rest. Higher maternal depression at 4 years moderated the relationship between early depression scores and functional connectivity within the phonological network. CONCLUSIONS: Maternal depression in the first year of life is related to functional connections of phonological processing and enhanced by current maternal depression levels. We conclude that after a mother gives birth, resources should be provided to minimize depressive symptoms and interventions should be applied to support their child's language development for future reading acquisition.

RESUMO

An adverse relationship between screen exposure time and brain functional/structural connectivity was reported in typically developing children, specifically related to neurobiological correlates of reading ability. As children with reading difficulties (RD) suffer from impairments in reading and executive functions (EF), we sought to determine the association between the ratio of screen time duration to reading time duration and functional connectivity of EF networks to the entire brain in children with RD compared to typical readers (TRs) using resting state data. Screen/reading time ratio was related to reduced reading and EF abilities. A larger screen/reading time ratio was correlated with increased functional connectivity between the salience network and frontal-EF regions in children with RD compared to TRs. We suggest that whereas greater screen/reading time ratio is related to excessive stimulation of the visual processing system in TRs, it may be related to decreased efficiency of the cognitive control system in RDs.

RESUMO

BACKGROUND: Maternal depression can influence the early activity of a mother reading stories to a young child, as depressed mothers are less likely to read to their children. Here, maternal depression association to neurobiological circuitry of narrative comprehension, visualization, and executive functions during stories listening was examined in 21 4-year-old girls and their mothers. Maternal depression scores were collected from the mothers, and functional MRI during stories listening was collected from the children. RESULTS: Increased maternal depression was related to decreased functional connectivity between visualization and auditory regions and increased connectivity between the right visual cortex and dorsolateral prefrontal cortex in the children. CONCLUSIONS: This study highlights the need to monitor maternal depression and provide interventions to ensure positive linguistic outcomes in children.

RESUMO

BACKGROUND: Screen-based media use is prevalent in children and is associated with health risks. American Academy of Pediatrics (AAP) recommendations involve access to screens, frequency, content, and co-viewing. The aim of this study was to test the ScreenQ, a composite measure of screen-based media use. METHODS: ScreenQ is a 15-item parent report measure reflecting AAP recommendations. Range is 0-26, higher scores reflecting greater non-adherence. With no "gold standard" available, four validated measures of skills and parenting practices cited as influenced by overuse were applied as the external criteria, including expressive language, speed of processing, emergent literacy, and cognitive stimulation at home. Psychometric analyses involved Rasch methods and Spearman's ρ correlations. RESULTS: Sixty-nine families were administered ScreenQ. Child age ranged from 36 to 63 months old (52 ± 8; 35 girls). Mean ScreenQ score was 9.6 (±5.0; 1-22). Psychometric properties were strong (rCo-α = 0.74). ScreenQ scores were negatively correlated with CTOPP-2 (Comprehensive Test of Phonological Processing, Second Edition) (rρ = -0.57), EVT-2 (Expressive Vocabulary Test, Second Edition) (rρ = -0.45), GRTR (Get Ready to Read!) (rρ = -0.30) and StimQ-P (rρ = -0.42) scores (all p ≤ 0.01). CONCLUSIONS: ScreenQ shows potential as a composite measure of screen-based media use in young children in the context of AAP recommendations. ScreenQ scores were correlated with lower executive, language and literacy skills, and less stimulating home cognitive environment.

RESUMO

Early language exposure and shared parent-child reading, as assessed by maternal reading ability and fluency, affect the child's future language and cognitive abilities. The aim of the current study was to explore the association between maternal reading ability and fluency and diffusion properties of language- and cognition-related white matter tracts in their pre-school age children using diffusion tensor imaging (DTI). DTI data were acquired from fifteen girls (mean age: 3.83 ± 0.49 years). Reading ability and fluency were assessed in their mothers. Effects of hemisphere and node on diffusion properties were measured at 100 points along white matter tracts related to language and cognitive abilities. Significant positive correlations were found between maternal reading ability and fractional anisotropy in left and right dorsal and ventral language and executive functions-related tracts, while maternal reading fluency was associated with higher fractional anisotropy in ventral tracts, mainly in the left hemisphere. Fractional Anisotropy was significantly higher in the left compared to the right arcuate, cingulum cingulate, and inferior longitudinal fasciculus and higher in the right compared to the left superior longitudinal fasciculus. Our results signify the importance of maternal reading as a facilitator of the child's future language and cognitive abilities.

RESUMO

AIM: Caregiver-child reading is advocated by health organisations, citing cognitive and neurobiological benefits. The influence of home literacy environment (HLE) on brain structure prior to kindergarten has not previously been studied. METHODS: Preschool-age children completed assessments of language (EVT-2, CTOPP-2 Rapid Object Naming) and emergent literacy skills (Get Ready to Read!, The Reading House) followed by diffusion tensor imaging (DTI). Parents completed a survey of HLE (StimQ-P2 READ), which has four subscales. DTI measures included axial diffusivity (AD), radial diffusivity (RD), mean diffusivity (MD) and fractional anisotropy (FA). RESULTS: Forty-seven children completed DTI (54 ± 7 months, range 36-63; 27 girls). StimQ-P2 READ scores correlated with higher EVT-2, GRTR and TRH scores, controlling for age and gender (P < .01), and also with lower AD, RD and MD in tracts supporting language and literacy skills, controlling for age, gender and income (P < .05, family-wise error corrected). Correlations were strongest for the Bookreading Quantity subscale, including with higher scores on all cognitive measures including CTOPP-2, and also with higher FA in left-lateralised literacy-supporting tracts, controlling for age, gender and income. CONCLUSION: More nurturing home reading environment prior to kindergarten may stimulate brain development supporting language and literacy skills, reinforcing the need for further study.

RESUMO

AIM: This study aimed to define whether individuals with drug-resistant focal epilepsy also used regions related to cognitive control to facilitate reading. METHODS: We focused on patients with drug-resistant focal epilepsy in 2011-2014, who were aged 8-20 years and were being treated at the Cincinnati Children's Hospital, USA. They performed a verb generation functional magnetic resonance imaging task known to involve language and cognitive control, as well as a formal reading assessment. The reading scores were correlated with functional connectivity of the anterior cingulate cortex (ACC) using seed-to-voxel analysis. RESULTS: There were 81 potential patients and 13 (seven females) met the inclusion criteria. Their age at seizure onset was 0-13 years, and they had a mean age of 12.66 ± 3.17 years at the time of the study. Individuals with epilepsy demonstrated average intelligence and word reading ability. Their reading scores were positively correlated with functional connectivity between the ACC and regions related to emotional processing (right amygdala), learning and language processing (left cerebellum) and visual processing. CONCLUSION: Our results support the role that the ACC plays in proficient reading among children with drug-resistant epilepsy, even in those with epileptogenic foci in areas related to language.

RESUMO

Reading is an acquired skill that relies on cognitive-control and language abilities. Home reading environment has been positively correlated with activation in parietal-temporal-occipital association cortex supporting mental imagery and narrative comprehension during a story-listening task in preschool-age children. However, the degree to which maternal reading ability influences early brain development, specifically neural circuits involved with language and reading, is not well understood. The current study explored the relationship between maternal reading ability and functional connectivity within the language network, between the language network and networks related to cognitive control and visual processing, as well as between the language network and the entire brain (network-to-voxel analysis) of preschool-age children during a resting state. Thirteen 4-year-old girls and their mothers participated in this study, involving cognitive testing and functional magnetic resonance imaging, including a resting-state scan. Maternal reading ability was negatively correlated with functional connectivity within the child's language network at rest, and also with areas involved in visual processing, cognitive-control, and semantics. These results suggest that children whose mothers exhibit decreased reading ability may demonstrate a greater engagement of the language network and neural circuits related to visual word recognition, cognitive-control, and semantic processing, which later in life support reading.

RESUMO

The role of the parent or educator in a child's learning is a key feature in child development. Evidence supports the impact of early language exposure for future language and cognitive abilities and of home reading environment on neural circuits supporting language and reading. As shared parent-child reading is largely contingent on the reading ability of the parent, the aim of the current study was to explore association of parental reading ability on functional connectivity of brain networks involved with reading acquisition in their children. Twenty-two 4-year-old girls and their mothers participated in the current study. Maternal reading fluency was applied as predictors of functional connectivity analyses of a stories-listening functional MRI task. Results indicate a positive association between maternal fluency scores and greater functional connectivity between regions in the future reading network and brain regions supporting language and cognitive control in the children. Maternal reading fluency is important in facilitating development of a child's reading network. Implications regarding shared reading are discussed, and an extended ecological model for child language and literacy development is proposed.

RESUMO

BACKGROUND: The American Academy of Pediatrics (AAP) recommends shared reading beginning as soon as possible after birth to promote healthy development. Shared reading quality can strongly influence outcomes, especially in children from low-SES households. Dialogic reading is a method developed to enhance verbal interactivity and engagement through book sharing, advocated by the AAP and clinic-based programs such as Reach Out and Read. There is no brief, validated, caregiver report measure of dialogic reading or shared reading quality currently available. METHODS: This cross-sectional study involved 49 healthy mother-child dyads (mean child age 4.5 yrs., SD = 0.6 yrs.) from 2 separate MRI-based studies. The DialogPR was administered by trained research coordinators following MRI, along with the READ subscale of the validated StimQ-P measure of home cognitive environment. The DialogPR consists of eight items developed in consultation with experts in early literacy, based on the PEER/CROWD dialogic reading conceptual model. Estimated reading level is 6th grade. Descriptive statistics were computed at both the item and scale levels. Modern theory Rasch methods were used to analyze all eight DialogPR items along with preliminary estimates of reliability and validity. RESULTS: Our combined sample involved 15 boys and 34 girls, and was diverse in terms of age, household income, and maternal education. DialogPR administration time was less than 2 min, with no problems reported. The DialogPR demonstrated strong internal consistency and reliability (Cronbach's alpha = 0.82), and criterion-related validity with the StimQ-P READ (Spearman's rho coefficient = 0.53). Rasch analysis revealed strong psychometric properties in terms of reliability, variability in item difficulty, and inter-item and item-measure correlations. CONCLUSIONS: Preliminary evidence suggests that the DialogPR may be an efficient means to assess shared reading quality and dialogic reading via caregiver report for clinical and research purposes, warranting further investigation.

RESUMO

AIM: This study compared the time spent using screen-based media or reading on the functional connectivity of the reading-related brain regions in children aged 8-12. METHODS: We recruited 19 healthy American children from a private school in Cincinnati, USA, in 2015-6 after advertising the study to parents. The parents completed surveys on how many hours their children spent on independent reading and screen-based media time, including smartphones, tablets, desktop or laptop computers and television. The children underwent magnetic resonance imaging that assessed their resting-state connectivity between the left visual word form area, as the seed area, and other brain regions, with screen time and reading time applied as predictors. RESULTS: Time spent reading was positively correlated with higher functional connectivity between the seed area and left-sided language, visual and cognitive control regions. In contrast, screen time was related to lower connectivity between the seed area and regions related to language and cognitive control. CONCLUSION: Screen time and time spent reading showed different effects on functional connectivity between the visual word form area and language, visual and cognitive control regions of the brain. These findings underscore the importance of children reading to support healthy brain development and literacy and limiting screen time.

RESUMO

OBJECTIVE: To explore the relationship between maternal shared reading quality (verbal interactivity and engagement) and brain function during story listening in at-risk, preschool-age children, in the context of behavioral evidence and American Academy of Pediatrics, recommendations. STUDY DESIGN: In this cross-sectional study, 22 healthy, 4-year-old girls from low socioeconomic status households completed functional magnetic resonance imaging using an established story listening task, followed by videotaped observation of uncoached mother-daughter reading of the same, age-appropriate picture book. Shared reading quality was independently scored applying dialogic reading and other evidence-based criteria reflecting interactivity and engagement, and applied as a predictor of neural activation during the functional magnetic resonance imaging task, controlling for income and maternal education. RESULTS: Shared reading quality scores were generally low and negatively correlated with maternal distraction by smartphones (P < .05). Scores were positively correlated with activation in left-sided brain areas supporting expressive and complex language, social-emotional integration, and working memory (P <.05, false discovery rate corrected). CONCLUSIONS: Maternal shared reading quality is positively correlated with brain activation supporting complex language, executive function, and social-emotional processing in at-risk, preschool-age children. These findings represent novel neural biomarkers of how this modifiable aspect of home reading environment may influence foundational emergent literacy skills, reinforce behavioral evidence and American Academy of Pediatrics, recommendations, and underscore the potential of dialogic reading interventions to promote healthy brain development, especially in at-risk households.

RESUMO

Reading is one of the most important academic abilities that establishes the foundation for a child's success in school. Therefore, early and accurate diagnosis of reading challenges is crucial for prevention of later academic failure. One challenge in early detection of reading difficulties is that the ability to read typically is acquired explicitly when a child is four to six years of age. However, reading ability relies on development of more basic abilities prior to reading acquisition, starting from birth. CONCLUSION: Language, cognitive control and literacy milestones can be evaluated and trained from birth to better acquire reading later in life.
