RESUMO

BACKGROUND: Evidence shows that greenspace exposure benefits children's health and cognitive development. However, evidence assessing this association in young children in low- and middle-income economies is scarce. OBJECTIVE: To assess the association between exposure to greenness and cognitive performance in pre-pubertal boys living in Mexico City. METHODS: Cross-sectional study using data from 144 boys aged 6-11 years living in Mexico City in 2017 and enrolled in the "MetCog" study. Cognitive performance was evaluated through selected Wechsler Scale for Intelligence in Children Fourth Edition (WISC-IV) and Neuropsychological Assessment of Children (Evaluación Neuropsicológica Infantil, ENI) tests. Exposure to greenness was assessed through Normalised Difference Vegetation Index (NDVI) at 300, 500, 1500, 2000, and 3000 m buffer zones from children's residences. Multiple linear regression analysis was undertaken to assess associations between cognitive performance and greenness (aß) with 95% confidence intervals (CI) and adjusted for potential confounding variables. Significance was set at q < 0.05 after False Discovery Rate (FDR) correction. RESULTS: A positive association was found between the NDVI Interquartile Range (IQR) at 2000 m and the WISC-IV block design test score (aß 2000 = 1.18, 95% CI = 0.31, 2.06; q < 0.05), which assesses perceptual reasoning. Positive associations were found with NDVI IQR at 1500 m and WISC-IV block design (aß1500 = 1.00, 95% CI = 0.14, 1.86) and matrix reasoning (aß1500 = 0.83, 95% CI = 0.06, 1.61) scores, but neither survived FDR correction. No significant associations were found between NDVI IQR at any buffer size with other WISC-IV and ENI task scores. CONCLUSIONS: Greater exposure to greenness was associated with higher perceptual reasoning skills in 144 pre-pubertal boys living in Mexico City. Thus, urban planning should consider increasing vegetation in megacities, especially in neighbourhoods with high percentages of young children.

RESUMO

Resumen El presente estudio se realizó con una población final de 292 niños y niñas de 12 escuelas públicas del departamento del Cauca en los grados transición, primero, segundo y tercero de básica. Para el propósito de la investigación se emplearon 36 pruebas de la batería de Evaluación Neuropsicológica Infantil (ENI), con una duración de 1h 20" por cada niño. Los objetivos que se establecieron en la presente investigación fueron: describir el desempeño de los niños en 35 pruebas neuropsicológicas; evaluar si el desempeño en estas pruebas variaba según factores como la edad del niño, su grado, su género y la institución educativa a la que asistía. El muestreo fue por conveniencia, en tanto que participaron de la investigación solo aquellos niños que fueron autorizados por sus padres o acudientes. Se les realizó valoración neuropsicológica, con la Batería de Evaluación Neuropsicológica Infantil (ENI), en forma individual durante las horas escolares; para ello se emplearon espacios condicionados de manera apropiada para tales propósitos, en las instalaciones de cada colegio. Dentro de los hallazgos relevantes, se observa que no hay diferencias significativas, en términos globales, en las diferentes pruebas, tanto en la condición de género, como en las edades. Es así como los niños y niñas más pequeños tienen comportamientos similares en las diferentes pruebas que los niños y niñas más grandes. La variable "indígena-no indígena", de igual manera, no presentó variación significativa alguna en las pruebas.


Abstract The present study has been performed with a final population of 292 children from 12 public schools in the department of Cauca in transition, first, second and third base grades. For the purpose of this investigation, 36 tasks of battery of child Neuropsychological evaluation was used (ENI), with a duration of 1h 20" per child. The objectives established in this investigation were to describe the performance of children in 35 neuropsychological tests to assess whether the performance in these tests varied according to factors such as the child's age, grade, gender, educational institution she attended. The statistical sampling was for convenience, while research-involving children whose parents or guardians authorized. They underwent to a neuropsychological assessment with Child Neuropsychological Evaluation (ENI) individually during school hours; for this, were used a space properly and appropriately conditioned for such purposes within each school facilities. Among the key findings observed no significant differences in overall terms, in the different tests both gender status, and age. This is how children and smaller girls have similar behavior in the different tests that children and older girls. "Indigenous - non-indigenous" variable also did not present any significant variation in the tests.

RESUMO

Introducción: las alteraciones en la función ejecutiva, especialmente en flexibilidad cognoscitiva, planeación,control inhibitorio y memoria de trabajo constituyen un elemento cardinal dentro las manifestaciones deltrastorno del espectro autista (TEA).Objetivo: el objetivo de este trabajo fue evaluar el desempeño de las pruebas de función ejecutiva en unapoblación de pacientes con trastorno del espectro autista (TEA).Materiales y métodos: se realizó un estudio observacional en niños de una institución de rehabilitación. Seevaluó el desempeño en las subpruebas de la evaluación neuropsicológica infantil, el puntaje de CARS (ChildhoodAutism Rating Scale) y otras variables, mediante un análisis de correlación de Spearman. El estudio fueaprobado por el Comité de Ética en Investigación y se obtuvo consentimiento de los padres.Resultados: se evaluaron ocho niños con edad promedio de 8,9 años (6,1-13,7) y puntaje CARS entre 32 y 46.Se encontró mejor desempeño en habilidades gráficas y menor fluidez gráfica y verbal y de flexibilidad cognitiva.La edad tuvo correlación directa con el puntaje en memoria de trabajo y con la capacidad de planeación.Un puntaje de CARS alto se correlacionó con bajo rendimiento en flexibilidad cognitiva, memoria de trabajoy fluidez gráfica no semántica.Conclusión: los niños con TEA son susceptibles de presentar alteraciones significativas en tareas relacionadascon las funciones ejecutivas, lo que puede explicar la tendencia a la perseveración, incapacidad de cambio decriterio y conductas estereotipadas. Esta disfunción se correlaciona con la severidad del autismo y varía segúnla edad. Aunque esta alteración no es un fenómeno que se presente exclusivamente en el TEA, constituye unelemento a tener en cuenta al momento de evaluar estos niños.


Introduction: executive function disturbances, especially in cognitive flexibility planning, inhibitory control and working memory constitute a cardinal element within the manifestations of autism spectrum disorder (ASD).Objective: the aim of this research was to evaluate the performance of executive function tests in children with ASD.Materials and methods: an observational study was conducted in children attending a rehabilitation institution. An analysis between the performance of the Childhood Neuropsychological assessment subtests, scores of CARS (Childhood Autism Rating Scale) and other variables was performed by a Spearman correlation test. The study was approved by the Institutional Ethics Committee and parental consent was obtained.Results: we evaluated eight children with a mean age of 8.9 years (min: 6.1, max: 13.7) and CARS score between 32 and 46. Better performance was found in graphical abilities, less in graphical and verbal fluency and in cognitive flexibility. Age was directly correlated with scores on working memory and planning. A high CARS score was correlated with poor performance on cognitive flexibility, working memory and non-semantic graphic fluency.Conclusion: children with ASD are prone to show disturbances in executive functions related tasks which may explain the inflexible adherence to routines, the persistence of stereotypical behaviors and the perseveration observed in ASD patients. This dysfunction correlates with the severity of autism and varies with age. Although this condition is not present exclusively in ASD, it is a factor to consider when evaluating children with autism.
