Publication Open Access Ideal cardiovascular health status and health-related quality of life in adolescents: the labmed physical activity study(Sao Paulo Pediatric Society, 2021) Agostinis-Sobrinho, César; Werneck, André de Oliveira; Kievišienė, Justina; Moreira, Carla; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun ZientziakObjective: Adolescent's ideal cardiovascular health index (ICVH) seems to be an important indicator of youth's lifestyles and cardiometabolic health with potential positive consequences for their Health-Related Quality of Life (HRQoL). The purpose of this study was to examine the associations between the ICVH index and HRQoL in adolescents. Methods: This was a cross-sectional study based on secondary analyses from the LabMed Physical Activity Study (n=407 adolescents, 53% girls). ICVH, as defined by the American Heart Association, was determined as meeting ideal behaviors (physical activity, body mass index, smoking status, and diet intake) and health factors (blood pressure, total glucose, and cholesterol). HRQoL was measured with the Kidscreen-10 self-report questionnaire. Results: Analysis of covariance (ANCOVA) showed a significant association between the accumulation of ideal cardiovascular health metrics and HRQoL (F(4,403)=4.160; p=0.003). In addition, the higher the number of ideal health behaviors accumulated, the higher the mean values of HRQoL (p-value for trend=0.001), after adjustments for age, sex, socioeconomic status and pubertal stage. Conclusions: ICVH index was positively associated with HRQoL in adolescents. Ideal health behaviors metrics seem to have a stronger association with HRQoL than the ideal health factors metrics in adolescents.Publication Open Access Pubertal stage, body mass index, and cardiometabolic risk in children and adolescents in Bogotá, Colombia: the cross-sectional FUPRECOL study(MDPI, 2017) Ramírez Vélez, Robinson; García Hermoso, Antonio; Agostinis-Sobrinho, César; Mota, Jorge; Santos, Rute; Correa Bautista, Jorge Enrique; Peña-Guzmán, Carlos Andrés; Domínguez Sánchez, María Andrea; Schmidt Río-Valle, Jacqueline; González Jiménez, Emilio; Ciencias de la Salud; Osasun ZientziakThis study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9¿17.9 years of age). Weight, height, and waist circumference were measured and body mass index (BMI) was calculated. A biochemical study was performed to determine the cardiometabolic risk index (CMRI). Blood pressure was evaluated and pubertal stage was assessed with the Tanner criteria. Hierarchical multiple regression analyses were performed. The most significant variable (p < 0.05) in the prognosis of cardiometabolic risk was found to be the BMI in both boys and girls. In the case of girls, the pubertal stage was also a CMRI predictive factor. In conclusion, BMI was an important indicator of cardiovascular risk in both sexes. Pubertal stage was associated with cardiovascular risk only in the girls.Publication Open Access Mode of commuting to school and its association with physical activity and sedentary habits in young ecuadorian students(MDPI, 2018) Barranco Ruiz, Yaira; Guevara-Paz, Alfredo Xavier; Ramírez Vélez, Robinson; Chillón, Palma; Villa González, Emilio; Ciencias de la Salud; Osasun ZientziakActive commuting to and from school (ACS) could help to increase daily physical activity levels in youth; however, this association remains unknown in Ecuadorian youth. Thus, the aims of this study were (1) to determine the patterns of commuting to and from school and (2) to analyze the associations between ACS, physical activity (PA), and sedentary habits in Ecuadorian youth. A total of 732 students (65.3% males), aged 10–18 years (children = 246, young adolescents = 310, older adolescents = 162) from the central region of Ecuador participated in this study. A self-report questionnaire, including the usual mode and frequency of commuting, distance from home to school (PACO-Questionnaire), and PA and sedentary habits (YAP-Questionnaire), was used. Most of the sample lived ≤2 km from school; however, they were mainly passive commuters (96%). The most common mode of commuting was by car (to school = 43.4%, from school = 31.6%; p < 0.001). Children presented significantly higher scores (0–4) in PA outside school and total PA compared with older adolescents (2.20 ± 0.97 vs. 1.97 ± 0.96; p = 0.013 and 2.30 ± 0.76 vs. 2.09 ± 0.74, p = 0.019, respectively), as well as the lowest scores in sedentary habits (1.51 ± 0.65, p < 0.001). PA at school and total PA were positively associated with ACS (OR 3.137; 95% CI, 1.918 to 5.131; p < 0.001, and OR 2.543; 95% CI, 1.428 to 4.527; p = 0.002, respectively). In conclusion, passive modes of transportation were the most frequently used to commute to and from school in young Ecuadorians. PA at school and total PA were positively associated with ACS. Thus, interventions at school setting could be an opportunity to improve PA levels and additionally ACS in youth from the central region of Ecuador.Publication Open Access Global prevalence and gender inequalities in at least 60 min of self-reported moderate-to-vigorous physical activity 1 or more days per week: an analysis with 707,616 adolescents(Elsevier, 2024) Araujo, Raphael H. O.; Werneck, André de Oliveira; Martins, Clarice M. L.; Barboza, Luciana L.; Tassitano, Rafael M.; Aguilar-Farias, Nicolas; Jesus, Gilmar M. de; Ramírez Vélez, Robinson; Tesler, Riki; Oyeyemi, Adewale L.; Silva, Ellen C. M.; Weaver, Robert G.; Tremblay, Mark S.; Brazo-Sayavera, Javier; Mielke, Grégore I.; Silva, Danilo R.; Ciencias de la Salud; Osasun ZientziakBackground: Guidelines recommend that adolescents should accumulate an average of 60 min per day of moderate-to-vigorous physical activity (MVPA). However, using only this cut-off could hide important information. For instance, from a population-level point of view, increasing physical activity for those with no or low physical activity could provide more health benefits than increasing physical activity for those with intermediate levels. Also, including a more sensitive cut-point of ≥1 days per week could be an additional strategy for identifying those with low access/opportunities for physical activity practice. Thus, the current study aims to estimate the prevalence of ≥60 min of MVPA ≥1 days per week among adolescents globally, and to describe any relevant gender inequalities. Methods: We used representative datasets from 146 countries/territories collected between 2003 and 2019. MVPA was self-reported. Participants were grouped into younger (≤14 years old) and older (>14 years old) adolescents. Crude Poisson regression models were used to identify the relative differences in ≥60 min of MVPA ≥1 days per week between boys and girls, and random-effects meta-analysis models were used to identify the pooled estimates. Analyses were stratified by country and region. Results: Approximately 80% of both younger and older adolescents reported ≥60 min of MVPA ≥1 days per week. This prevalence was ≥94% in Europe and Central Asia and North America, while the estimates for the other regions were <77%. The prevalence of ≥60 min of MVPA ≥1 days per week was higher among boys than girls, with the largest differences occurring among the oldest adolescents (Prevalence ratio≤14y = 1.04 (95% confidence interval (95%CI)): 1.03‒1.04) vs. Prevalence ratio>14y = 1.09 (95%CI: 1.08‒1.10)). Conclusion: Approximately 8 out of 10 adolescents reported accumulating ≥60 min of MVPA ≥1 days per week, with notable differences between regions. Gender differences were observed in several countries, especially among the oldest adolescents. Priorities for physical activity promotion among adolescents should include increasing access/opportunities for physical activity among those who do not achieve ≥60 min of MVPA ≥1 days per week and reducing gender inequalities.Publication Open Access Higher cardiorespiratory fitness levels may attenuate the detrimental association between weight status, metabolic phenotype and C-reactive protein in adolescents—a multi-cohort study(MDPI, 2020) Agostinis-Sobrinho, César; Rosário, Rafaela; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua, CENEDUCA1/2019; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaResults from several studies show that only obese, unfit subjects, but not obese, fit subjects, are at higher mortality risk than are normal-weight fit subjects. The aim of the study was two-fold: (1) to examine the differences in C-reactive protein levels across different metabolic phenotypes (healthy and unhealthy) of weight status and (2) ascertain whether high levels of cardiorespiratory fitness (CRF) attenuate the association of C-reactive protein and metabolic phenotypes of weight status. This was a pooled study, which included data from three cross-sectional projects (1706 youth (921 girls) aged 12–18 years). We used a Shuttle run test to assess CRF. Adolescents were classified into six metabolic phenotypes (healthy and unhealthy) of weight status (non-overweight, overweight and obese), based on age-and sex-specific cutoff points for triglycerides, systolic blood pressure, HDL-cholesterol, glucose and body mass index. High-sensitivity assays were used to obtain the C-reactive protein as inflammatory biomarker. After adjustment for potential confounders (age, sex, pubertal stage and country), the analysis of covariance (ANCOVA) shows that C-reactive protein is directly associated with metabolic phenotypes of weight status. Subjects with obesity, regardless of their metabolic profile, had higher levels of C-reactive protein Z-score. In addition, (after adjustments for potential confounders) a two-way ANCOVA showed that high levels of CRF attenuated the associations of C-reactive protein levels in metabolic healthy nonoverweight and in adolescents with obesity. In conclusion, higher CRF levels may attenuate the detrimental association between obesity and C-reactive protein independently of metabolic phenotype. Findings from this study are important for prevention, clinical practice on issues associated with adiposity and metabolic disorders.Publication Open Access Grip strength moderates the association between anthropometric and body composition indicators and liver fat in youth with an excess of adiposity(MDPI, 2018) Ramírez Vélez, Robinson; Izquierdo Redín, Mikel; Correa Bautista, Jorge Enrique; Tordecilla Sanders, Alejandra; Correa Rodríguez, María; Schmidt Río-Valle, Jacqueline; González Jiménez, Emilio; González Ruiz, Katherine; Ciencias de la Salud; Osasun ZientziakPaediatric non-alcoholic fatty liver disease (NAFLD) is considered the most common early driver of chronic liver disease. The aim of this study was to examine whether grip strength moderates the association between anthropometric and body composition parameters and controlled attenuation parameter (CAP), an indicator of fat deposits in the liver, in children and adolescents with excess of adiposity. A total of 127 adolescents (67% girls) aged between 11 and 17, attending two public schools in Bogota (Colombia), who had an axiological evaluation of obesity were included in this study. A grip strength test was assessed as an indicator of muscular strength, and cardiorespiratory fitness by maximal oxygen uptake was assessed using the 20 m shuttle-run test. Waist circumference (WC), waist-to-height ratio (WHtR), fat mass, and visceral adipose tissue (VAT) (cm(3)) were included as anthropometric and body composition measures. CAP was determined with a FibroScan((R)) 502 Touch device (Echosens, Paris, France). The anthropometric and body composition parameters including WC, WHtR, fat mass, and VAT were positively associated with the CAP (range = 0.423 to 0.580), slightly reduced after being adjusted for handgrip strength/weight. The Johnson-Neyman technique revealed a significant inverse relationship between WC, WHtR, VAT, and CAP when grip strength normalized by body mass was above but not equal to or below 0.475 (8.1% of the sample), 0.469 (8.9% of the sample), and 0.470 (8.5% of the sample), respectively. In conclusion, grip strength adjusted by body mass, has a moderating effect on the association between anthropometric and body composition parameters (including WC, WHtR, and VAT) and CAP in in children and adolescents with excess of adiposity, suggesting the importance of promoting muscular strength during paediatric population in order to prevent NAFLD.Publication Open Access Optimal adherence to a mediterranean diet may not overcome the deleterious effects of low physical fitness on cardiovascular disease risk in adolescents: a cross-sectional pooled analysis(MDPI, 2018) Agostinis-Sobrinho, César; Santos, Rute; Rosário, Rafaela; Moreira, Carla; Lopes, Luís; Mota, Jorge; Martinkenas, Arvydas; García Hermoso, Antonio; Correa Bautista, Jorge Enrique; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun ZientziakTo examine the combined association of cardiorespiratory fitness (CRF), muscular fitness (MF), and adherence to a Mediterranean diet (MeDiet) on cardiovascular risk in adolescents, a pooled study, including cross-sectional data from two projects [2477 adolescents (1320 girls) aged 12-18 years], was completed. A shuttle run test was used to assess CRF. MF was assessed by the standing-long jump and handgrip tests. Adherence to a MeDiet was assessed by the Kidmed questionnaire. A cardiovascular risk score was computed from the following components: Age and sex, waist circumference, triglycerides, systolic blood pressure, high-density lipoprotein cholesterol (HDL), and glucose. Analysis of covariance showed that participants classified as having optimal (High) adherence to a MeDiet/HighMF/HighCRF, as well those classified as low adherence to a MeDiet/HighMF/HighCRF, had, on average, the lowest cardiovascular risk score (F = 15.6; p < 0.001). In addition, the high adherence to a MeDiet/LowMF/LowCRF group had the highest odds of having a high cardiovascular risk (OR = 7.1; 95% CI: 3.4-15.1; p < 0.001), followed by the low adherence to a MeDiet/LowMF/LowCRF group (OR = 3.7; 95% CI: 2.2-6.3; p < 0.001), high adherence to a MeDiet/HighMF/LowCRF group (OR = 3.1; 95% CI: 1.4-7.0; p = 0.006), and low adherence to a MeDiet/LowMF/HighCRF group (OR = 2.5; 95% CI: 1.5-4.4; p = 0.002) when compared to those with high adherence to a MeDiet/HighMF/HighCRF, after adjustments for potential confounders. In conclusion, our findings showed that, regardless of the MeDiet status, adolescents with low MF and low CRF cumulatively, presented the highest cardiovascular disease risk. Therefore, these findings suggest that the combination of these two fitness components may be beneficial to adolescents¿ cardiometabolic profile, independent of MeDiet behaviour.Publication Open Access Association of physical education with improvement of health-related physical fitness outcomes and fundamental motor skills among youths: a systematic review and meta-analysis(American Medical Association (AMA), 2020-08-31) García Hermoso, Antonio; Alonso Martínez, Alicia; Ramírez Vélez, Robinson; Pérez Sousa, Miguel A.; Ramírez Campillo, Rodrigo; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun ZientziakThis systematic review and meta-analysis of 55 studies that included 37 563 youths revealed that cardiorespiratory fitness levels and change over approximately 1 year during youth were associated with lower risk of developing obesity and cardiometabolic disease later in life. These early associations detected from baseline to follow-up dissipated over time. The study suggests that prevention strategies that target youth cardiorespiratory fitness may be associated with improved health parameters in later life.
