Publication Open Access Effects of exercise on hepatic steatosis in children: role of fitness(2019) Medrano Echeverría, María; Labayen Goñi, Idoia; Ciencias de la Salud; Osasun ZientziakLos objetivos principales de esta Tesis Doctoral Internacional fueron: I) examinar si la capacidad cardiorrespiratoria se relaciona con la concentración plasmática de enzimas hepáticas en adolescentes europeos independientemente de la circunferencia de cintura, y testar si tener una mayor capacidad cardiorrespiratoria está asociada con un mejor perfil de enzimas hepáticas en aquellos adolescentes con una mayor circunferencia de cintura; II) explorar la asociación de los componentes de la condición física y la actividad física con el porcentaje de grasa hepática, las concentraciones plasmáticas de enzimas hepáticas, la resistencia a la insulina y el riesgo cardiometabólico en niñas y niños con sobrepeso u obesidad; III) analizar sistemáticamente el efecto del ejercicio físico supervisado en el porcentaje de grasa hepática y en la prevalencia de esteatosis hepática en niños y adolescentes; investigar el diseño de ejercicio más apropiado en términos de tipo, intensidad, volumen y frecuencia, para el manejo de la esteatosis hepática pediátrica; y explorar si existe una asociación entre las mejorar de la capacidad cardiorrespiratoria y la fuerza muscular con la reducción del porcentaje de grasa hepática en jóvenes; IV) determinar si un programa de intervención multicomponente de 22 semanas de duración, basado en educación familiar en estilos de vida saludable y psicoeducación que incluya además ejercicio físico supervisado, es más efectivo reduciendo el porcentaje de grasa hepática que solamente el programa educativo en niñas y niños con sobrepeso u obesidad; y V) analizar la variabilidad interindividual y comparar la prevalencia de respondedores en relación con el porcentaje de grasa hepática, la adiposidad total y abdominal y las concentraciones plasmáticas de gamma-glutamil-transferasa en los niñas y niños participantes en una intervención basada en educación familiar en estilos de vida saludable y psicoeducación de 22 semanas de duración, que incluya o no ejercicio físico.Publication Open Access Perceived quality of life is related to a healthy lifestyle and related outcomes in spanish children and adolescents: The physical activity, sedentarism, and obesity in spanish study(MDPI, 2023) Ródenas-Munar, Marina; Monserrat-Mesquida, Margalida; Gómez, Santiago F.; Wärnberg, Julia; Medrano Echeverría, María; González Gross, Marcela; Gusi, Narcís; Aznar, Susana; Marín-Cascales, Elena; González Valeiro, Miguel A.; Serra-Majem, Lluis; Pulgar, Susana; Segú, Marta; Fitó, Montserrat; Torres, Silvia; Benavente-Marín, Juan C.; Labayen Goñi, Idoia; Zapico, Augusto G.; Sánchez-Gómez, Jesús; Jiménez-Zazo, Fabio; Alcaraz, Pedro E.; Sevilla-Sánchez, Marta; Herrera-Ramos, Estefanía; Schröder, Helmut; Bouzas, Cristina; Tur, Josep A.; Ciencias de la Salud; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOODBackground: Maintaining a healthy lifestyle is crucial for safeguarding the well-being and quality of life perception, appropriate growth, and development of children and adolescents, while also mitigating the risk of future adult-onset diseases. Objective: To assess associations between perceived quality of life and healthy lifestyle and related outcomes in Spanish children and adolescents. Methods: Cross-sectional analysis of 8–16-year-old children and adolescents (n = 3534) were included in the nationwide study of Physical Activity, Sedentarism, and Obesity in Spanish Youth (PASOS). Data were collected through (1) questionnaires on health-related quality of life (HRQoL), healthy lifestyle outcomes (dietary intake, physical fitness, sleep, and screen time), and (2) anthropometric measurements for weight status assessment. Data were analysed by logistic regression, using the health-related quality of life (HRQoL) as the grouping variable. Results: Participants with a lower HRQoL were those with a lower adherence to the MedDiet and lower achievement of the recommended daily intake of fruit and vegetables. They were also less likely to follow the recommendations for screen time and sleep (with the exception of the weekend) compared to participants with a higher HRQoL. Participants with a lower HRQoL showed a lower healthy weight status and poorer physical fitness than those with a higher HRQoL. Conclusions: Healthy eating habits, healthy weight status (normal weight), appropriate sleep time, physical fitness, and limited screen time play a crucial role in the perceived quality of life in children and adolescents.Publication Open Access Prevention of diabetes in overweight/obese children through a family based intervention program including supervised exercise (PREDIKID project): study protocol for a randomized controlled trial(BioMed Central, 2017) Arenaza Etxeberría, Lide; Medrano Echeverría, María; Amasene, María; Rodríguez Vigil, Beatriz; Díez, Ignacio; Graña, Manuel; Tobalina, Ignacio; Maiz, Edurne; Arteche, Edurne; Larrarte, Eider; Huybrechts, Inge; Davis, Catherine L.; Ruiz, Jonatan R.; Ortega, Francisco B.; Margareto, Javier; Labayen Goñi, Idoia; Ciencias de la Salud; Osasun ZientziakBackground: The global pandemic of obesity has led to an increased risk for prediabetes and type-2 diabetes (T2D). The aims of the current project are: (1) to evaluate the effect of a 22-week family based intervention program, including supervised exercise, on insulin resistance syndrome (IRS) risk in children with a high risk of developing T2D and (2) to identify the profile of microRNA in circulating exosomes and in peripheral blood mononuclear cells in children with a high risk of developing T2D and its response to a multidisciplinary intervention program including exercise. Methods: A total of 84 children, aged 8–12 years, with a high risk of T2D will be included and randomly assigned to control (N = 42) or intervention (N = 42) groups. The control group will receive a family based lifestyle education and psycho-educational program (2 days/month), while the intervention group will attend the same lifestyle education and psycho-educational program plus the exercise program (3 days/week, 90 min per session including warm-up, moderate to vigorous aerobic activities, and strength exercises). The following measurements will be evaluated at baseline prior to randomization and after the intervention: fasting insulin, glucose and hemoglobin A1c; body composition (dual-energy X-ray absorptiometry); ectopic fat (magnetic resonance imaging); microRNA expression in circulating exosomes and in peripheral blood mononuclear cells (MiSeq; Illumina); cardiorespiratory fitness (cardiopulmonary exercise testing); dietary habits and physical activity (accelerometry). Discussion: Prevention and identification of children with a high risk of developing T2D could help to improve their cardiovascular health and to reduce the comorbidities associated with obesity.Publication Open Access Differences in areal bone mineral density between metabolically healthy and unhealthy overweight/obese children: the role of physical activity and cardiorespiratory fitness(Springer Nature, 2019) Ubago Guisado, Esther; Gracia-Marco, Luis; Medrano Echeverría, María; Cadenas-Sánchez, Cristina; Arenaza Etxeberría, Lide; Migueles, Jairo H.; Mora González, José; Tobalina, Ignacio; Escolano Margarit, María Victoria; Osés Recalde, Maddi; Martín Matillas, Miguel; Labayen Goñi, Idoia; Ortega, Francisco B.; Institute on Innovation and Sustainable Development in Food Chain - ISFOODObjectives: To examine whether areal bone mineral density (aBMD) differs between metabolically healthy (MHO) and unhealthy (MUO) overweight/obese children and to examine the role of moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness (CRF) in this association. Methods: A cross-sectional study was developed in 188 overweight/obese children (10.4 ± 1.2 years) from the ActiveBrains and EFIGRO studies. Participants were classified as MHO or MUO based on Jolliffe and Janssen’s metabolic syndrome cut-off points for triglycerides, glucose, high-density cholesterol and blood pressure. MVPA and CRF were assessed by accelerometry and the 20-m shuttle run test, respectively. Body composition was measured by dual-energy X-ray absorptiometry. Results: In model 1 (adjusted for sex, years from peak high velocity, stature and lean mass), MHO children had significantly higher aBMD in total body less head (Cohen’s d effect size, ES = 0.34), trunk (ES = 0.43) and pelvis (ES = 0.33) than MUO children. These differences were attenuated once MVPA was added to model 1 (model 2), and most of them disappeared once CRF was added to the model 1 (model 3). Conclusions: This novel research shows that MHO children have greater aBMD than their MUO peers. Furthermore, both MVPA and more importantly CRF seem to partially explain these findings.Publication Open Access Comparison of bioelectrical impedance analysis, slaughter skinfold-thickness equations, and dual-energy x-ray absorptiometry for estimating body fat percentage in Colombian children and adolescents with excess of adiposity(MDPI, 2018) González Ruiz, Katherine; Medrano Echeverría, María; Correa Bautista, Jorge Enrique; García Hermoso, Antonio; Prieto Benavides, Daniel Humberto; Institute on Innovation and Sustainable Development in Food Chain - ISFOODDual-energy X-ray absorptiometry (DXA) has been considered a reference method for measuring body fat percentage (BF%) in children and adolescents with an excess of adiposity. However, given that the DXA technique is impractical for routine field use, there is a need to investigate other methods that can accurately determine BF%. We studied the accuracy of bioelectrical impedance analysis (BIA) technology, including foot-to-foot and hand-to-foot impedance, and Slaughter skinfold-thickness equations in the measurement of BF%, compared with DXA, in a population of Latin American children and adolescents with an excess of adiposity. A total of 127 children and adolescents (11-17 years of age; 70% girls) from the HEPAFIT (Exercise Training and Hepatic Metabolism in Overweight/Obese Adolescent) study were included in the present work. BF% was measured on the same day using two BIA analysers (Seca((R)) 206, Allers Hamburg, Germany and Model Tanita((R)) BC-418((R)), TANITA Corporation, Sportlife Tokyo, Japan), skinfold measurements (Slaughter equation), and DXA (Hologic Horizon DXA System((R)), Quirugil, Bogota, Columbia). Agreement between measurements was analysed using t-tests, Bland-Altman plots, and Lin's concordance correlation coefficient (c). There was a significant correlation between DXA and the other BF% measurement methods (r > 0.430). According to paired t-tests, in both sexes, BF% assessed by BIA analysers or Slaughter equations differ from BF% assessed by DXA (p < 0.001). The lower and upper limits of the differences compared with DXA were 6.3-22.9, 2.2-2.8, and -3.2-21.3 (95% CI) in boys and 2.3-14.8, 2.4-20.1, and 3.9-18.3 (95% CI) in girls for Seca((R)) mBCA, Tanita((R)) BC 420MA, and Slaughter equations, respectively. Concordance was poor between DXA and the other methods of measuring BF% (c < 0.5). BIA analysers and Slaughter equations underestimated BF% measurements compared to DXA, so they are not interchangeable methods for assessing BF% in Latin American children and adolescents with excess of adiposity.Publication Open Access Peripheral blood mononuclear cells-expressed miRNA profiles derived from children with metabolic-associated fatty liver disease and insulin resistance(Wiley, 2022) Osés Recalde, Maddi; Medrano Echeverría, María; Margareto, Javier; Portillo, María P.; Aguilera, Concepción María; Altmäe, Signe; Labayen Goñi, Idoia; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Gobierno de Navarra / Nafarroako GobernuaBackground: miRNA have been proposed as potential biomarkers of metabolic diseases. Objectives: To identify potential miRNA biomarkers of early metabolic-associated fatty liver disease (MAFLD) and/or insulin resistance (IR) in preadolescent children. Methods: A total of 70 preadolescents, aged 8.5–12 years old participated in the study. Hepatic fat was assessed by magnetic resonance imaging. Fasting blood biochemical parameters were measured and HOMA-IR calculated. Peripheral blood mononuclear cells (PBMC)-derived miRNA profiles associated with MAFLD (≥5.5% hepatic fat) and IR (HOMA-IR ≥2.5) were identified using untargeted high-throughput miRNAs sequencing (RNA-seq). Results: A total of 2123 PBMC-derived miRNAs were identified in children with (21.4%) or without MAFLD. Among them, hsa-miR-143-3p, hsa-miR-142-5p and hsamiR-660-5p were up-regulated, and p-hsa-miR-247, hsa-let-7a-5p and hsa-miR6823-3p down-regulated. Importantly, children with MAFLD had consistently higher miR-660-5p expression levels than their peers without it (p < 0.01), regardless of weight status. A total of 2124 PBMC-derived miRNA were identified in children with IR (28.6%) versus children without IR, where thirteen of them were dysregulated (p < 0.05) in children with IR. In addition, children with IR showed higher levels of miR-374a-5p and miR-190a-5p (p < 0.01) and lower levels of miR-4284 and miR4791 (p < 005), than their peers without IR in both the whole sample and in those with overweight or obesity. Conclusions: Our study results suggest circulating miR-660-5p as a potential biomarker of the presence of MAFLD in preadolescent children while circulating miR320a, miR-142-3p, miR-190a-5p, miR-374a-5p and let-7 family miRNAs could serve as potential biomarkers of IR in children.
