“…When considering the aspect of EF subscales, we found only inhibition and working memory related to excess weight. This finding was consistent with the previous study that showed a significant association between these EF subscales and weight excess [ 42 , 43 ]. For EF subscale–inhibition, the possible link between inhibition and the risk of having excess weight is unhealthy eating behaviors.…”

The association between executive function and excess weight is becoming increasingly evident. However, the results of previous studies are still inconclusive, and there is a lack of evidence in early childhood. This study aims to examine the association between executive function, in terms of overall and subscales of executive function (e.g., inhibition, working memory, and shifting), and weight excess in preschoolers. A population-based cross-sectional study was conducted on children aged 2–5 years of age from public and private schools in Chiang Mai, Thailand. Participants’ weights and heights were measured and classified into three weight status groups (i.e., children with normal weight, overweight, and obesity groups). Executive function was assessed using the parent-report Behavior Rating Inventory of Executive Function-Preschool (BRIEF-P). Multivariable polynomial regression was performed to analyze the association between executive function and weight status. A total of 1,181 children were included in the study. After adjusting for confounders, impaired overall executive function significantly increased the probability of being overweight (odds ratio [OR] = 2.47; 95% confidence interval [CI] 1.33 to 4.56). A similar trend of association was also found between impaired inhibition and overweight status (OR = 2.33; 95%CI 1.11 to 4.90). Furthermore, poor working memory was associated with both overweight and obesity (OR = 1.87; 95%CI 1.09 to 3.20 and OR = 1.74; 95%CI 1.09 to 2.78, respectively). Our data suggest that deficits in executive function, particularly inhibition and working memory, are associated with weight excess in preschoolers. Early promotion of executive function may be needed at this developmental age to prevent unhealthy weight status.

“…Girls with a healthier BMI performed better by successfully completing the task with a higher number of trials, compared with girls with a higher BMI who did not successfully complete the test. In a study in Saudi Arabia girls aged 8–12 reported that every increase in the BMI category shows a decrease in working memory scores 43 . These results indicate that girls with overweight and obesity BMI had greater difficulty in capturing new elements and precise details in trials.…”

This effect may be attributable to women coding events with more detailed and fine processing, due to activation of the left hemisphere amygdala.…”

Summary Objective To evaluate the association between body mass index (BMI) and performance of executive functions (EFs) in girls and boys with 9‐ and 10‐year‐old schoolchildren with moderate‐ to vigorous‐intensity physical activity (MVPA) and sedentary behaviour. Methods A total of 120 schoolchildren (61 girls and 59 boys) were evaluated anthropometrically. The MVPA was evaluated with a self‐report questionnaire. EFs were measured using a neuropsychological battery of Executive Functions and Frontal Lobes‐2 (BANFE‐2). Results A high BMI was associated with longer delay in completing inhibitory control tests (p = 0.00, rp = 0.32) and working memory (p = 0.00, rp = 0.26). We observed correlations in time (p = 0.00, rp = −0.43) and hits (p = 0.04, rp = −0.27) of self‐directed signalling test in boys; and girls in alphabetical words order (p = 0.00, rp = −0.39). Active normal weight schoolchildren (ANw) performed better by successfully completed the working memory tasks (H = 26.97, p = 0.00) than sedentary schoolchildren with overweight and obesity. In addition, overweight‐active schoolchildren (AOw) showed better performance on working memory tests in time (p = 0.00) and hits (p = 0.01) than their sedentary peers. Multiple linear regression analysis revealed a significant association between BMI and EFs scores (F = 2.41, df = 98, p = 0.001). Conclusions EFs are affected by a high BMI and sedentary behaviour in school children. Boys and girls reflected differences to solve the same challenges. The MVPA has a positive effect on executive control skills mainly in overweight children.

Introducción: Uno de los enfoques de investigación en fisiología del metabolismo corporal ha sido evaluar el efecto de la obesidad sobre los procesos de aprendizaje y memoria. Este trabajo tiene como objetivo describir y analizar los principales hallazgos científicos relacionados con las posibles afectaciones en la memoria y el aprendizaje, a causa de la obesidad en diferentes grupos etarios, a partir de estudios en humanos y modelos murinos. Materiales y métodos: Para la búsqueda electrónica de literatura se utilizaron las bases de datos Biblioteca Virtual de Salud, Biological Science Database, Biomed Central, Ebsco, Nature, PubMed, Scielo y Science Direct en el período 2010-2021. Con base en los criterios de inclusión y exclusión y la evaluación del título y del resumen, se seleccionaron los artículos a analizar para esta revisión de tema. Resultados: La obesidad genera alteraciones sobre el aprendizaje y la memoria en todos los grupos etarios, específicamente sobre la memoria a largo plazo, la memoria espacial y la memoria de trabajo, así como en la expresión de marcadores asociados a la función cognitiva, principalmente BDNF. Esta epidemia produce afectaciones relacionadas con la memoria de trabajo, la atención y el rendimiento escolar; aunque estos hallazgos fueron diferentes en cada estudio. Adicionalmente, se ha reportado disminución en la expresión del factor neurotrófico derivado del cerebro (BDNF), así como en la expresión de otras proteínas, particularmente en el hipocampo, las cuales se relacionan con la función cognitiva. Conclusiones: La obesidad pregestacional y gestacional impacta negativamente estos procesos en la descendencia y según el grupo etario originan afectaciones en la neuroplasticidad y en diferentes componentes de la función cognitiva. Sin embargo, se requiere profundizar en la investigación puesto que algunos hallazgos son contradictorios y falta información de otras áreas encefálicas relacionadas y la reversibilidad de estos efectos.
