    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 - ISFOOD
    Objectives: 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.

    Validity, reliability, and calibration of the physical activity unit 7 item screener (PAU-7S) at population scale
    (BioMed Central, 2021) Schröder, Helmut; Subirana, Isaac; Wärnberg, Julia; Medrano Echeverría, María; González Gross, Marcela; Gusi, Narcís; Aznar, Susana; Alcaraz, Pedro E.; González Valeiro, Miguel A.; Serra-Majem, Lluis; Terrados, Nicolás; Tur, Josep A.; Segú, Marta; Homs, Clara; García-Álvarez, Alicia; Benavente-Marín, Juan C.; Barón-López, F.

    Background: Validation of self-reported tools, such as physical activity (PA) questionnaires, is crucial. The aim of this study was to determine test-retest reliability, internal consistency, and the concurrent, construct, and predictive validity of the short semi-quantitative Physical Activity Unit 7 item Screener (PAU-7S), using accelerometry as the reference measurement. The effect of linear calibration on PAU-7S validity was tested. Methods: A randomized sample of 321 healthy children aged 8–16 years (149 boys, 172 girls) from the nationwide representative PASOS study completed the PAU-7S before and after wearing an accelerometer for at least 7 consecutive days. Weight, height, and waist circumference were measured. Cronbach alpha was calculated for internal consistency. Test-retest reliability was determined by intra-class correlation (ICC). Concurrent validity was assessed by ICC and Spearman correlation coefficient between moderate to vigorous PA (MVPA) derived by the PAU-7S and by accelerometer. Concordance between both methods was analyzed by absolute agreement, weighted kappa, and Bland-Altman statistics. Multiple linear regression models were fitted for construct validity and predictive validity was determined by leave-one-out cross-validation.

    Association of breakfast quality and energy density with cardiometabolic risk factors in overweight/obese children: role of physical activity
    (MDPI, 2018) Arenaza Etxeberría, Lide; Muñoz-Hernández, Victoria; Medrano Echeverría, María; Osés Recalde, Maddi; Amasene, María; Merchán Ramírez, Elisa; Cadenas-Sánchez, Cristina; Ortega, Francisco B.; Ruiz, Jonatan R.; Labayen Goñi, Idoia; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    There is a general belief that having breakfast is an important healthy lifestyle factor; however, there is scarce evidence on the influence of breakfast quality and energy density on cardiometabolic risk in children, as well as on the role of physical activity in this association. The aims of this paper were (i) to examine the associations of breakfast quality and energy density from both solids and beverages with cardiometabolic risk factors, and (ii) to explore whether physical activity levels may attenuate these relationships in children with overweight/obesity from two projects carried out in the north and south of Spain. Breakfast consumption, breakfast quality index (BQI) score, BEDs/BEDb (24 h-recalls and the KIDMED questionnaire), and physical activity (PA; accelerometry) were assessed, in 203 children aged 8-12 years who were overweight or obese. We measured body composition (Dual X-ray Absorptiometry), uric acid, blood pressure, lipid profile, gamma-glutamyl-transferase (GGT), glucose, and insulin, and calculated the HOMA and metabolic syndrome z-score. The BQI score was inversely associated with serum uric acid independently of a set of relevant confounders (= -0.172, p = 0.028), but the relationship was attenuated after further controlling for total PA (p < 0.07). BEDs was positively associated with total and HDL cholesterol, and systolic blood pressure regardless of confounders (all p < 0.05), while BEDb was positively associated with HOMA in either active/inactive children (all p < 0.03). In conclusion, higher breakfast quality and lower breakfast energy density should be promoted in overweight/obesity children to improve their cardiometabolic health.

    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 Zientziak
    Background: 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.

    The effect of a multicomponent intervention on steatosis is partially mediated by the reduction of intermuscular abdominal adipose tissue in children with overweight or obesity: the EFIGRO Project
    (American Diabetes Association, 2022) Cadenas-Sánchez, Cristina; Idoate, Fernando; Cabeza Laguna, Rafael; Villanueva Larre, Arantxa; Rodríguez Vigil, Beatriz; Medrano Echeverría, María; Osés Recalde, Maddi; Ortega, Francisco B.; Ruiz, Jonatan R.; Labayen Goñi, Idoia; Osasun Zientziak; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren; Institute of Smart Cities - ISC; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Ciencias de la Salud; Ingeniería Eléctrica, Electrónica y de Comunicación; Gobierno de Navarra / Nafarroako Gobernua
    OBJECTIVE: In adults, there is evidence that improvement of metabolic-associated fatty liver disease (MAFLD) depends on the reduction of myosteatosis. In children, in whom the prevalence of MAFLD is alarming, this muscle-liver crosstalk has not been tested. Therefore, we aimed to explore whether the effects of a multicomponent intervention on hepatic fat is mediated by changes in intermuscular abdominal adipose tissue (IMAAT) in children with overweight/obesity. RESEARCH DESIGN AND METHODS: A total of 116 children with overweight/obesity were allocated to a 22-week family-based lifestyle and psychoeducational intervention (control group, n = 57) or the same intervention plus supervised exercise (exercise group, n = 59). Hepatic fat percentage and IMAAT were acquired by MRI at baseline and at the end of the intervention. RESULTS: Changes in IMAAT explained 20.7% of the improvements in hepatic steatosis (P < 0.05). Only children who meaningfully reduced their IMAAT (i.e., responders) had improved hepatic steatosis at the end of the intervention (within-group analysis: responders -20% [P = 0.005] vs. nonresponders -1.5% [P = 0.803]). Between-group analysis showed greater reductions in favor of IMAAT responders compared with nonresponders (18.3% vs. 0.6%, P = 0.018), regardless of overall abdominal fat loss. CONCLUSIONS: The reduction of IMAAT plays a relevant role in the improvement of hepatic steatosis after a multicomponent intervention in children with overweight/obesity. Indeed, only children who achieved a meaningful reduction in IMAAT at the end of the intervention had a reduced percentage of hepatic fat independent of abdominal fat loss. Our findings suggest that abdominal muscle fat infiltration could be a therapeutic target for the treatment of MAFLD in childhood.

    The effect of a family-based lifestyle education program on dietary habits, hepatic fat and adiposity markers in 8-12-year-old children with overweight/obesity
    (MDPI, 2020) Arenaza Etxeberría, Lide; Medrano Echeverría, María; Osés Recalde, Maddi; Amasene, María; Díez, Ignacio; Rodríguez Vigil, Beatriz; Labayen Goñi, Idoia; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    Healthy lifestyle education programs are recommended for obesity prevention and treatment. However, there is no previous information on the effects of these programs on the reduction of hepatic fat percentage. The aims were (i) to examine the effectiveness of a 22-week family-based lifestyle education program on dietary habits, and (ii) to explore the associations of changes in dietary intake with percent hepatic fat reduction and adiposity in children with overweight/obesity. A total of 81 children with overweight/obesity (aged 10.6 ± 1.1 years, 53.1% girls) and their parents attended a 22-week family based healthy lifestyle and psychoeducational program accompanied with (intensive group) or without (control) an exercise program. Hepatic fat (magnetic resonance imaging), adiposity (dual energy X-ray absorptiometry) and dietary habits (two non-consecutive 24 h-recalls) were assessed before and after the intervention. Energy (p < 0.01) fat (p < 0.01) and added sugar (p < 0.03) intake were significantly reduced in both groups at the end of the program, while, in addition, carbohydrates intake (p < 0.04) was reduced exclusively in the control group, and simple sugar (p < 0.05) and cholesterol (p < 0.03) intake was reduced in the exercise group. Fruit (p < 0.03) and low-fat/skimmed dairy consumption (p < 0.02), the adherence to the Mediterranean Diet Quality Index for children and teenagers (KIDMED, p < 0.01) and breakfast quality index (p < 0.03) were significantly higher in both control and intervention groups after the intervention. Moreover, participants in the exercise group increased the adherence to the Dietary Approaches to Stop Hypertension (DASH) diet (p < 0.001), whereas the ratio of evening-morning energy intake was significantly lower exclusively in the control group after the program (p < 0.02). Changes in energy intake were significantly associated with changes in fat mass index (FMI) in the exercise group, whereas changes in sugar-sweetened beverages (SSB) consumption was associated with percent hepatic fat reduction (p < 0.05) in the control group. A 22-week family-based healthy lifestyle program seems to be effective on improving diet quality and health in children with overweight/obesity and these should focus on SSB avoidance and physical activity.

    La actividad física se define como 'cualquier movimiento corporal producido por los músculos esqueléticos que tiene como resultado un gasto de energía'. Acciones como caminar, subir las escaleras, realizar tareas del hogar, entrenar fuerza, jugar un partido de cualquier deporte o jugar a las palas en la playa son/implican actividad física. El ejercicio físico y el deporte son dos subtipos diferentes de actividad física. La característica distintiva del ejercicio físico es que se realiza de manera estructurada, planificada y repetitiva y con un objetivo determinado. El deporte se caracteriza por tener carácter competitivo, que se rige bajo unas reglas, y en muchas ocasiones se engloba dentro de una estructura federativa o institucionalizada. La realización de ejercicio físico va a influir sobre los requerimientos nutricionales de la persona que la realiza afectando no solo las necesidades energéticas, sino también las de macro y micronutrientes e hidratación. La práctica de ejercicio físico conlleva un aumento del gasto energético que puede suponer un incremento de los requerimientos energéticos que, a su vez, precisan de un aumento de la ingesta energética. La dieta del deportista deberá aportar la energía necesaria, en el momento necesario, aportada mediante una buena planificación también en su composición de macro- y micronutrientes. En ocasiones concretas, la práctica de ejercicio físico puede buscar también superávits o déficits energéticos puntuales o sostenidos, que precisan asimismo de una buena planificación. La planificación dietética de un/una deportista depende de varios factores que tienen que ver con las características morfológicas y de composición corporal del/la deportista, con la disciplina que practica, la cual determinará los sustratos energéticos y rutas metabólicas predominantes de la misma, con los objetivos a corto y largo plazo, y con la fase de la temporada en la que se encuentre. Todos estos aspectos van a determinar la planificación dietética en relación con la ingesta energética, su composición en macronutrientes y su distribución a lo largo del día. El ejercicio físico también va a aumentar los requerimientos de otros nutrientes. Es necesario que haya un correcto aporte de los micronutrientes, vitaminas y minerales (especialmente de los indispensables), que participan en las rutas metabólicas empleadas durante el ejercicio físico para que pueda alcanzarse un buen rendimiento, se produzcan las adaptaciones fisiológicas buscadas con el entrenamiento, y poder preservar la salud del deportista y evitar lesiones. Una correcta hidratación es importante en todas las personas, pero juega un papel determinante en el rendimiento deportivo. Por ello, se deberán diseñar estrategias específicas que permitan al deportista estar correctamente hidratado. Si bien es cierto que no todas las personas que realizan actividad física tienen requerimientos nutricionales especiales y su dieta seguirá los principios nutricionales básicos de una dieta equilibrada. En determinadas ocasiones, puede ser muy difícil cubrir los requerimientos nutricionales del deportista exclusivamente a través de una dieta basada en alimentos, y se recurre a ayudas ergogénicas nutricionales para lograr este objetivo u otros que influyen en el rendimiento deportivo. En general, las personas que realizan menos de una hora de ejercicio físico habitual y estructurado pueden satisfacer sus necesidades nutricionales siguiendo las recomendaciones para una vida activa que se proponen para la población general. En aquellas personas que realizan niveles elevados de ejercicio físico, principalmente deportistas que buscan el máximo rendimiento deportivo, son precisas planificación y recomendaciones dietéticas especiales que se conocen genéricamente como Nutrición Deportiva y cuyas consideraciones y recomendaciones generales se recogen en el este capítulo.

    Study protocol of a population-based cohort investigating physical activity, sedentarism, lifestyles and obesity in Spanish youth: the PASOS study
    (BMJ, 2020) Gómez, Santiago F.; Homs, Clara; Wärnberg, Julia; Medrano Echeverría, María; Labayen Goñi, Idoia; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    Introduction Physical activity (PA) is essential to healthy mental and physical development in early life. However, the prevalence of physical inactivity, which is considered a key modifiable driver of childhood obesity, has reached alarming levels among European youth. There is a need to update the data for Spain, in order to establish if current measures are effective or new approaches are needed. Methods and analysis We present the protocol for Physical Activity, Sedentarism, lifestyles and Obesity in Spanish youth (PASOS). This observational, nationally representative, multicentre study aims to determine the PA levels, sedentary behaviours and prevalence of physical inactivity (defined as <60 min of moderate to vigorous PA per day) in a representative sample of Spanish children and adolescents. The PASOS study has recruited a representative random sample of children and adolescents aged 8-16 years from 242 educational centres in the 17 'autonomous regions' into which Spain is divided. The aim is to include a total of 4508 youth participants and their families. Weight, height and waist circumference will be measured by standardised procedures. Adherence to the Mediterranean diet, quality of life, sleep duration, PA and sedentary behaviour are being measured by validated questionnaires. PA is measured by the Physical Activity Unit 7-item Screener. A representative subsample (10% of participants) was randomly selected to wear accelerometers for 9 days to obtain objective data on PA. Parents are asked about their educational level, time spent doing PA, diet quality, self-perceived stress, smoking habit, weight, height, their child's birth weight and if the child was breast fed.

    Differences in specific abdominal fat depots between metabolically healthy and unhealthy children with overweight/obesity: the role of cardiorespiratory fitness
    (Wiley, 2023) Cadenas-Sánchez, Cristina; Medrano Echeverría, María; Villanueva Larre, Arantxa; Cabeza Laguna, Rafael; Idoate, Fernando; Osés Recalde, Maddi; Rodríguez Vigil, Beatriz; Álvarez de Eulate, Natalia; Alberdi Aldasoro, Nerea; Ortega, Francisco B.; Labayen Goñi, Idoia; Ciencias de la Salud; Ingeniería Eléctrica, Electrónica y de Comunicación; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Institute of Smart Cities - ISC; Osasun Zientziak; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren
    Objectives: Fat depots localization has a critical role in the metabolic health status of adults. Nevertheless, whether that is also the case in children remains under- studied. Therefore, the aims of this study were: (i) to examine the differ-ences between metabolically healthy (MHO) and unhealthy (MUO) overweight/obesity phenotypes on specific abdominal fat depots, and (ii) to further explore whether cardiorespiratory fitness plays a major role in the differences between metabolic phenotypes among children with overweight/obesity. Methods: A total of 114 children with overweight/obesity (10.6 ±1.1 years, 62 girls) were included. Children were classified as MHO (n=68) or MUO. visceral (VAT), abdominal subcutaneous (ASAT), intermuscular abdominal (IMAAT), psoas, hepatic, pancreatic, and lumbar bone marrow adipose tissues were measured by magnetic resonance imaging. Cardiorespiratory fitness was assessed using the 20 m shuttle run test. Results: MHO children had lower VAT and ASAT contents and psoas fat fraction compared to MUO children (difference =12.4%– 25.8%, all p<0.035). MUO- unfit had more VAT and ASAT content than those MUO- fit and MHO- fit (difference =34.8%– 45.3%, all p<0.044). MUO- unfit shows also greater IMAAT fat fraction than those MUO- fit and MHO- fit peers (difference =16.4%– 13.9% respectively, all p≤0.001). In addition, MHO- unfit presented higher IMAAT fat fraction than MHO- fit (difference =13.4%, p<0.001). MUO- unfit presented higher psoas fat fraction than MHO- fit (difference =29.1%, p=0.008). Conclusions: VAT together with ASAT and psoas fat fraction, were lower in MHO than in MUO children. Further, we also observed that being fit, regardless of metabolic phenotype, has a protective role over the specific abdominal fat depots among children with overweight/obesity.

    Development of a prediction protocol for the screening of metabolic associated fatty liver disease in children with overweight or obesity
    (Wiley, 2022) Osés Recalde, Maddi; Cadenas-Sánchez, Cristina; Medrano Echeverría, María; Galbete Jiménez, Arkaitz; Miranda Ferrúa, Emiliano; Ruiz, Jonatan R.; Sánchez-Valverde, Félix; Ortega, Francisco B.; Cabeza Laguna, Rafael; Villanueva Larre, Arantxa; Idoate, Fernando; Labayen Goñi, Idoia; Osasun Zientziak; Institute of Smart Cities - ISC; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Ciencias de la Salud; Gobierno de Navarra / Nafarroako Gobernua
    Background: the early detection and management of children with metabolic associ-ated fatty liver disease (MAFLD) is challenging. Objective: to develop a non-invasive and accurate prediction protocol for the identi-fication of MAFLD among children with overweight/obesity candidates to confirma-tory diagnosis. Methods: a total of 115 children aged 8–12 years with overweight/obesity, rec-ruited at a primary care, were enrolled in this cross-sectional study. The external vali-dation was performed using a cohort of children with overweight/obesity (N=46)aged 8.5–14.0 years. MAFLD (≥5.5% hepatic fat) was diagnosed by magnetic reso-nance imaging (MRI). Fasting blood biochemical parameters were measured, and25 candidates’ single nucleotide polymorphisms (SNPs) were determined. Variablespotentially associated with the presence of MAFLD were included in a multivariatelogistic regression. Results: children with MAFLD (36%) showed higher plasma triglycerides (TG),insulin, homeostasis model assessment ofinsulin resistance (HOMA-IR), alanineaminotransferase (ALT), aspartate transaminase (AST), glutamyl-transferase (GGT)and ferritin (p< 0.05). The distribution of the risk-alleles of PPARGrs13081389, PPARGrs1801282, HFErs1800562 and PNLPLA3rs4823173 was significantly different between children with and without MAFLD (p<0.05). Threebiochemical- and/or SNPs-based predictive models were developed, showingstrong discriminatory capacity (AUC-ROC: 0.708–0.888) but limited diagnosticperformance (sensitivity 67%–82% and specificity 63%–69%). A prediction proto-col with elevated sensitivity (72%) and specificity (84%) based on two consecutive steps was developed. The external validation showed similar results: sensitivity of 70% and specificity of 85%. Conclusions: the HEPAKID prediction protocol is an accurate, easy to implant, minimally invasive and low economic cost tool useful for the early identification and management of paediatric MAFLD in primary care.
