Purpose: Early recognition of risk factors associated with overweight/obesity is animportant step towards preventing long-term health consequences. The aim of the current study was to examine the associations of the adherence to the Mediterranean dietary pattern (MDP) and cardiorespiratory fitness (CRF) with adiposity in preschool children from thenorth of Spain. Methods: The adherence to the MDP (KIDMED), CRF (20-m shuttle run test), total (BMI) and central (waist circumference) adiposity and socio-demographic factors were assessed in 619 children (48.6% girls) who were on average 4.7 years old. Results: Higher MDP index (P < 0.05) and CRF levels (P < 0.01) were significantly related to lower waist circumference. CRF was inversely associated with BMI (P <= 0.001), yet no significant association was observed between MDP and BMI. Children not having high CRF levels and high MDP (i.e., non-upper sex-specific tertile of CRF or MDP, respectively) had the highest waist circumference. Conclusions: Our findings support that higher adherence to the MDP and higher CRF are associated with lower waist circumference in preschool children, pointing them as relevant modifiable factors to be targeted by educational strategies aiming to prevent central obesity and later obesity-related comorbidities.

A.; Delgado Alfonso, Álvaro; Sanchís Moysi, Joaquín; Martínez Vizcaíno, Vicente; Chillón, Palma; PREFIT Project Group; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The aims of this study were to describe patterns of active commuting to school (ACS) of preschool children, and to analyse the relationship between ACS and family socio-economic factors. A total of 2636 families of preschoolers (3-to-5 years old) were asked to complete a questionnaire at home about the mode of commuting to school of their children and marital status, educational level, and profession of both father and mother. Chi-square analyses were applied to compare ACS between school grades and gender of the children. To analyse the association of ACS with socio-economic factors, logistic regression analyses were performed. Almost 50% of participants reported ACS of their offspring, with a higher rate in 3rd preprimary grade (5 years old) than in 1st and 2nd preprimary grades (3-and 4-years old. All, p <0.05). Those preschool children who had parents with lower educational level and no managerial work had higher odds to ACS than those who had parents with higher educational level and managerial work (all, p ≤ 0.001). Around half of the Spanish preschool children included in this study commuted actively to school and families with lower educational levels or worse employment situation were related to active commuting to school.

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.

(American Physiological Society, 2023) Plaza Florido, Abel; Esteban Cornejo, Irene; Mora González, José; Torres-López, Lucía V.; Osuna Prieto, Francisco J.; Gil Cosano, José J.; Radom-Aizik, Shlomit; Labayen Goñi, Idoia; Ruiz, Jonatan R.; Altmäe, Signe; Ortega, Francisco B.; Ciencias de la Salud; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
We investigated the interaction between a genetic score and an exercise intervention on brain health in children with overweight/obesity. One hundred one children with overweight/obesity (10.0 ± 1.5 yr, 59% girls) were randomized into a 20-wk combined exercise intervention or a control group. Several cognitive and academic outcomes were measured with validated tests. Hippocampal volume was quantified using magnetic resonance imaging. Six brain health-related polymorphisms [rs6265 (BDNF), rs2253206 (CREB1), rs2289656 (NTRK2), rs4680 (COMT), rs429358, and rs7412 (APOE)] were genotyped. Cognitive flexibility and academic skills improved significantly more in the exercise than in the control group only in the children with a “favorable” genetic profile [mean z-score, 0.41–0.67 (95% CI 0.11 to 1.18)], yet not in those with “less favorable” genetic profile. An individual response analysis showed that children responded to exercise in cognitive flexibility only in the “genetically favorable” group [i.e., 62% of them had a meaningful (≥0.2 Cohen d) increase in the exercise group compared with only 25% in the control group]. This finding was consistent in per-protocol and intention-to-treat analyses (P = 0.01 and P = 0.03, respectively). The results were not significant or not consistent for the rest of outcomes studied. Our findings suggest that having a more favorable genetic profile makes children with overweight/obesity more responsive to exercise, particularly for cognitive flexibility.

Association between UCP1, UCP2, and UCP3 gene polymorphisms with markers of adiposity in European adolescents: The HELENA study
(Wiley, 2019) Pascual Gamarra, José Miguel; Salazar-Tortosa, Diego; Martínez Téllez, Borja; Labayen Goñi, Idoia; Rupérez, Azahara I.; Censi, Laura; Manios, Yannis; Nova, Esther; Gesteiro, Eva; Moreno, Luis A.; Meirhaeghe, Aline; Ruiz, Jonatan R.; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Ciencias de la Salud
Aims: To examine the association between UCP1, UCP2, and UCP3 gene polymorphisms with adiposity markers in European adolescents and to test if there were gene interactions with objectively measured physical activity and adiposity. Methods: A cross-sectional study that involves 1.057 European adolescents (12-18 years old) from the Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study. A total of 18 polymorphisms in UCP1, UCP2, and UCP3 genes were genotyped. We measured weight, height, waist, and hip circumferences and triceps and subscapular skinfold thickness. Physical activity was objectively measured by accelerometry during 7 days. Results: The C allele of the UCP1 rs6536991 polymorphism was associated with a lower risk of overweight (odds ratio [OR]: T/C + C/C vs T/T) = 0.72; 95% confidence interval [CI]: 0.53-0.98; P = 0.034; false discovery rate [FDR] = 0.048). There was a significant interaction between UCP1 rs2071415 polymorphism and physical activity with waist-to-hip ratio (P = 0.006; FDR = 0.026). Adolescents who did not meet the physical activity recommendations (less than 60 min/day of moderate to vigorous physical activity) and carrying the C/C genotype had higher waist-to-hip ratio (+ 0.067; 95% CI, 0.028-0.106; P = 0.003), while no differences across genotypes were observed in adolescents meeting the recommendations. Conclusions: Two UCP1 polymorphisms were associated with adiposity in European adolescents. Meeting the daily physical activity recommendations may overcome the effect of the UCP1 rs2071415 polymorphism on obesity-related traits.

Association of meal timing with body composition and cardiometabolic risk factors in young adults
(Springer, 2023) Dote-Montero, Manuel; Acosta, Francisco M.; Sánchez Delgado, Guillermo; Merchán Ramírez, Elisa; Amaro Gahete, Francisco J.; Labayen Goñi, Idoia; Ruiz, Jonatan R.; Ciencias de la Salud; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
Purpose: To investigate the association of meal timing with body composition and cardiometabolic risk factors in young adults. Methods: In this cross-sectional study participated 118 young adults (82 women; 22±2 years old; BMI: 25.1±4.6 kg/m2). Meal timing was determined via three non-consecutive 24-h dietary recalls. Sleep outcomes were objectively assessed using accelerometry. The eating window (time between frst and last caloric intake), caloric midpoint (local time at which≥50% of daily calories are consumed), eating jetlag (variability of the eating midpoint between non-working and working days), time from the midsleep point to frst food intake, and time from last food intake to midsleep point were calculated. Body composition was determined by DXA. Blood pressure and fasting cardiometabolic risk factors (i.e., triglycerides, total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, and insulin resistance) were measured. Results: Meal timing was not associated with body composition (p>0.05). The eating window was negatively related to HOMA-IR and cardiometabolic risk score in men (R2=0.348, β=−0.605; R2=0.234, β=−0.508; all p≤0.003). The time from midsleep point to frst food intake was positively related to HOMA-IR and cardiometabolic risk score in men (R2=0.212, β=0.485; R2=0.228, β=0.502; all p=0.003). These associations remained after adjusting for confounders and multiplicity (all p≤0.011). Conclusions: Meal timing seems unrelated to body composition in young adults. However, a longer daily eating window and a shorter time from midsleep point to frst food intake (i.e., earlier frst food intake in a 24 h cycle) are associated with better cardiometabolic health in young men.

Background & aims: time-restricted eating (TRE) shows promise for weight loss and improving menopauserelated body composition and cardiometabolic health, but its effects on skeletal muscle tissue (SMT) in postmenopausal women are unknown. This study investigates the effects of three weight loss interventions over 12 weeks on SMT quantity, quality, function, and cardiometabolic health in postmenopausal women with overweight/obesity, with effects persistence evaluated at a 12-month follow-up. Methods and results: in this randomized controlled trial, 78 postmenopausal women (50–65 years; BMI 25–40 kg/m2; sedentary lifestyle; eating window ≥12 h/day; no severe metabolic impairments) will be recruited. Participants will be randomly assigned to one of three groups for 12 weeks: TRE, TRE + resistance training, or CR + resistance training. The TRE groups will reduce their eating window to 8 h and receive nutritional advice to adhere to a Mediterranean diet. The CR group will follow a personalized hypocaloric diet (− 500 kcal/day). Resistance training groups will perform supervised resistance training 3 times/week. Primary Outcome: Change in SMT quantity measured by MRI at baseline and after 12 weeks. Secondary Outcomes: intermuscular adipose tissue (IMAT), strength, power, body weight and composition, and cardiometabolic risk factors. Conclusion: this study will illustrate the effects of TRE and TRE combined with resistance exercise compared with the currently recommended obesity-lifestyle treatment on SMT quantity, quality, function, and cardiometabolic markers. The results will offer insights into dietary strategies to combat obesity and metabolic diseases without increasing sarcopenia risk in postmenopausal women, a sparsely studied and particularly affected population.

Energy expenditure and macronutrient oxidation in response to an individualized nonshivering cooling protocol
(Wiley, 2020) Sánchez Delgado, Guillermo; Alcántara Alcántara, Juan Manuel; Acosta, Francisco M.; Martínez Téllez, Borja; Amaro Gahete, Francisco J.; Merchán Ramírez, Elisa; Löf, Marie; Labayen Goñi, Idoia; Ravussin, Eric; Ruiz, Jonatan R.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
Objective This study aimed to describe the energy expenditure (EE) and macronutrient oxidation response to an individualized nonshivering cold exposure in young healthy adults. Methods Two different groups of 44 (study 1: 22.1 [SD 2.1] years old, 25.6 [SD 5.2] kg/m(2), 34% men) and 13 young healthy adults (study 2: 25.6 [SD 3.0] years old, 23.6 [SD 2.4] kg/m(2), 54% men) participated in this study. Resting metabolic rate (RMR) and macronutrient oxidation rates were measured by indirect calorimetry under fasting conditions in a warm environment (for 30 minutes) and in mild cold conditions (for 65 minutes, with the individual wearing a water-perfused cooling vest set at an individualized temperature adjusted to the individual's shivering threshold). Results In study 1, EE increased in the initial stage of cold exposure and remained stable for the whole cold exposure (P < 0.001). Mean cold-induced thermogenesis (9.56 +/- 7.9 kcal/h) was 13.9% +/- 11.6% of the RMR (range: -14.8% to 39.9% of the RMR). Carbohydrate oxidation decreased during the first 30 minutes of the cold exposure and later recovered up to the baseline values (P < 0.01) in parallel to opposite changes in fat oxidation (P < 0.01). Results were replicated in study 2. Conclusions A 1-hour mild cold exposure individually adjusted to elicit maximum nonshivering thermogenesis induces a very modest increase in EE and a shift of macronutrient oxidation that may underlie a shift in thermogenic tissue activity.

Interplay of the mediterranean diet and genetic hypertension risk on blood pressure in european adolescents: findings from the HELENA study
(Springer, 2024) Pérez-Gimeno, Gloria; Seral-Cortes, Miguel; Sabroso-Lasa, Sergio; Esteban, Luis Mariano; Widhalm, Kurt; Gottrand, Frédéric; Stehle, Peter; Meirhaeghe, Aline; Muntaner, Manon; Kafatos, Antonios; Gutiérrez, Ángel; Manios, Yannis; Anastasiou, Costas A.; González Gross, Marcela; Breidenassel, Christina; Censi, Laura; Henauw, Stefaan de; Labayen Goñi, Idoia; Bueno-Lozano, Gloria; Rupérez, Azahara I.; Moreno, Luis A.; Ciencias de la Salud; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
Early-life onset of high blood pressure is associated with the development of cardiovascular diseases in adulthood. In adolescents, limited evidence exists regarding the association between adherence to the Mediterranean Diet (MedDiet) and normal blood pressure (BP) levels, as well as its potential to modulate genetic predisposition to HTN. This study investigated the interaction between a MedDiet score and a recently developed HTN-genetic risk score (HTN-GRS) on blood pressure levels in a European adolescent cohort. The MedDiet score was derived from two non-consecutive 24-h dietary recalls and ranged from 0 (indicating low adherence) to 9 (indicating high adherence). Multiple linear regression models, adjusted for covariates, were employed to examine the relationship between the MedDiet score and BP z-scores and to assess the interaction effects between the MedDiet score and HTN-GRS on BP z-scores. MedDiet score showed a negative association with z-systolic BP (SBP) (ß = -0.40, p < 0.001) and z-diastolic BP (DBP) (ß = -0.29, p = 0.001). Additionally, a significant interaction effect was identified between the MedDiet score and HTN-GRS on z-SBP (ß = 0.02, p < 0.001) and z-DBP (ß = 0.02, p < 0.001). The modulatory effect of the MedDiet was more pronounced in females than in males, and HTN-GRS exhibited a stronger influence on DBP than on SBP. Conclusion: The study suggests that higher adherence to the MedDiet is associated with reduced BP levels in adolescents and provides evidence of a genetic-diet interaction influencing BP in adolescents.

The effect of an online exercise programme on bone health in paediatric cancer survivors (iBoneFIT): study protocol of a multi-centre randomized controlled trial
(BioMed Central, 2020) Gil Cosano, José J.; Ubago Guisado, Esther; Sánchez, María José; Ortega Acosta, María J.; Mateos, María E.; Benito Bernal, Ana I.; Labayen Goñi, Idoia; Llorente-Cantarero, Francisco J.; Ortega, Francisco B.; Ruiz, Jonatan R.; Martínez Vizcaíno, Vicente; Vlachopoulos, Dimitris; Arroyo Morales, Manuel; Muñoz Torres, Manuel; Pascual Gázquez, Juan F.; Vicho González, Maria C.; Gracia-Marco, Luis; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Ciencias de la Salud
Background: New approaches on paediatric cancer treatment aim to maintain long-term health. As a result of radiotherapy, chemotherapy or surgery, paediatric cancer survivors tend to suffer from any chronic health condition. Endocrine dysfunction represents one of the most common issues and affects bone health. Exercise is key for bone mass accrual during growth, specifically plyometric jump training. The iBoneFIT study will investigate the effect of a 9-month online exercise programme on bone health in paediatric cancer survivors. This study will also examine the effect of the intervention on body composition, physical fitness, physical activity, calcium intake, vitamin D, blood samples quality of life and mental health. Methods: A minimum of 116 participants aged 6 to 18 years will be randomized into an intervention (n = 58) or control group (n = 58). The intervention group will receive an online exercise programme and diet counselling on calcium and vitamin D. In addition, five behaviour change techniques and a gamification design will be implemented in order to increase the interest of this non-game programme. The control group will only receive diet counselling. Participants will be assessed on 3 occasions: 1) at baseline; 2) after the 9 months of the intervention; 3) 4 months following the intervention. The primary outcome will be determined by dual energy X-ray absorptiometry (DXA) and the hip structural analysis, trabecular bone score and 3D-DXA softwares. Secondary outcomes will include anthropometry, body composition, physical fitness, physical activity, calcium and vitamin D intake, blood samples, quality of life and mental health. Discussion: Whether a simple, feasible and short in duration exercise programme can improve bone health has not been examined in paediatric cancer survivors. This article describes the design, rationale and methods of a study intended to test the effect of a rigorous online exercise programme on bone health in paediatric cancer survivors. If successful, the iBoneFIT study will contribute to decrease chronic health conditions in this population and will have a positive impact in the society.
