Publication Open Access A before-school physical activity intervention to improve cognitive parameters in children: The Active-Start study(Wiley, 2019-08-19) García Hermoso, Antonio; Hormazábal Aguayo, Ignacio; Fernández Vergara, Omar; González-Calderón, Nicole; Russell-Guzmán, Javier; Vicencio-Rojas, Francisca; Chacana-Canas, Cesar; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun ZientziakThe aim of the study was threefold: (a) to test a before-school physical activity intervention (Active-Start) on academic performance, selective attention, and concentration capacity; (b) to test the effect of the Active-Start intervention on anthropometry, body composition, and physical fitness parameters; and (c) whether the physical fitness components are moderators of the effect of the Active-Start program on academic performance, selective attention, and concentration capacity in Chilean children. The Active-Start intervention was a RCT which comprised 170 children (8-10 years old) from three public schools with low socioeconomic status from the city of Santiago (Chile). The exercise intervention was delivered daily, before starting the first school-class (8:00-8:30 am) for 8 weeks. Changes in academic performance, selective attention and concentration capacity, anthropometric, body composition, and physical fitness parameters were measured. The analyses used were mixed regression models for repeated measures over time. No statistically significant changes in attention and concentration capacity were found. However, significant changes were seen in language (0.63; 95% CI 0.49-0.77) and mathematics (0.49; 95% CI 0.32-0.66) performance (P < .001). Also, improvements were seen in fat mass, fat-free mass, muscular, and cardiorespiratory fitness (all P < .05). The Johnson-Neyman technique revealed a significant relationship between the effect of intervention and attention and concentration when change in cardiorespiratory fitness was above, but not below, 3.05 and 0.70 mL/kg/min, respectively. Implementing before-school physical activity programs such as the Active-Start to enhance the cardiorespiratory fitness may benefit attention capacity and academic success among schoolchildren.Publication Embargo Is physical fitness associated with leucocyte telomere length in youth with type 1 diabetes?(Springer, 2024-11-14) Muñoz Pardeza, Jacinto; López Gil, José Francisco; Huerta Uribe, Nidia; Hormazábal Aguayo, Ignacio; Ojeda-Rodríguez, Ana; Martí del Moral, Amelia; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ciencias de la Salud; Osasun ZientziakBackground: in type 1 diabetes, telomere length (TL) may predict complications and could be influenced by glycaemic control and physical activity, but its relationship with physical fitness in youths remains unexplored. The aim of the study was to assess the association between physical fitness and TL in youth with type 1 diabetes, both at baseline and one year later. Methods: eighty-three children and adolescents (aged 6-18 years; 44.6% girls) with type 1 diabetes from the Diactive-1 Cohort Study were involved in this study. Physical fitness was assessed using spirometry on a cycloergometer (i.e., peak oxygen consumption), dynamometry, and maximal isometric strength (one-repetition maximum [1RM]), and muscle power. Leucocyte TL was assessed using multiplex monochrome real-time quantitative polymerase chain reaction. Results: positive cross-sectional associations were identified between 1RM (unstandardized beta coefficient [B] = 0.042, 95% bias corrected and accelerated [BCa] confidence interval [CI] 0.012-0.069), muscle power (B = 0.056, 95% BCa CI 0.02-0.250), and overall physical fitness (B = 0.043, 95% BCa CI 0.015¿0.071) with TL independent of maturation, glycated haemoglobin, and diabetes duration. However, no associations were observed one year later. Conclusion: higher levels of fitness, particularly muscle strength, may play a role in telomere dynamics in youth with type 1 diabetes, suggesting that strength training exercise could be beneficial. Impact: this is the first study to examine cross-sectional and longitudinal perspectives on the correlation among muscle strength, peak oxygen consumption [VO2peak] and telomere length in youths with type 1 diabetes. Higher physical fitness levels, as assessed by measures such as one-repetition maximum, muscle power, and overall physical fitness, are positively associated with telomere length in youths with type 1 diabetes. Understanding this link could improve management strategies, prioritizing muscle strength training for better long-term health in type 1 diabetes.Publication Open Access Nonpharmacological interventions on glycated haemoglobin in youth with type 1 diabetes: a Bayesian network meta-analysis(BMC, 2024-07-01) Muñoz Pardeza, Jacinto; López Gil, José Francisco; Huerta Uribe, Nidia; Hormazábal Aguayo, Ignacio; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ciencias de la Salud; Osasun ZientziakThe available evidence on the impact of specific non-pharmacological interventions on glycaemic control is currently limited. Consequently, there is a need to determine which interventions could provide the most significant benefits for the metabolic health of young individuals with type 1 diabetes mellitus. The aim of this study was to identify optimal nonpharmacological interventions on glycaemic control, measured by glycated haemoglobin (HbA1c), in children and adolescents with type 1 diabetes. Systematic searches were conducted in PubMed, Web of Science, Scopus, and SPORTDiscus from inception to July 1, 2023. Randomised clinical trials (RCT) investigating nonpharmacological interventions (e.g., physical activity, nutrition, and behavioural therapies) were included. Primary outcome was change in HbA1c levels. Secondary outcome was change in daily insulin dose requirement. Seventy-four RCT with 6,815 participants (49.43% girls) involving 20 interventions were analysed using a network meta-analysis. Most interventions showed greater efficacy than standard care. However, multicomponent exercise, which includes aerobic and strength training (n = 214, standardised mean difference [SMD] =– 0.63, 95% credible interval [95% CrI] – 1.09 to – 0.16) and nutritional supplements (n = 146, SMD =– 0.49, – 0 .92 to – 0.07) demonstrated the greatest HbA1c reductions. These interventions also led to the larger decreases in daily insulin needs (n = 119, SMD =– 0.79, 95% CrI – 1.19 to – 0.34) and (n = 57, SMD =– 0.62, 95% CrI – 1.18 to – 0.12, respectively). The current study underscores non-pharmacological options such as multicomponent exercise and nutritional supplements, showcasing their potential to significantly improve HbA1c in youth with type 1 diabetes. Although additional research to confirm their efficacy is required, these approaches could be considered as potential adjuvant therapeutic options in the management of type 1 diabetes among children and adolescents.Publication Open Access Youth with type 1 diabetes mellitus are more inactive and sedentary than apparently healthy peers: a systematic review and meta-analysis(Elsevier, 2023) Huerta Uribe, Nidia; Hormazábal Aguayo, Ignacio; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaAims: To conduct a meta-analysis of differences in physical activity, sedentary behaviour, and physical fitness between children and adolescents with type 1 diabetes and their healthy peers. Methods: The databases EMBASE, PubMed and SportsDiscus were searched for studies. Pooled effects were calculated using random effects inverse-variance models with the Hartung–Knapp–Sidik–Jonkman adjustment. Results: Thirty-five studies were included, comprising a total of 4,751 youths (53% girls, 2,452 with type 1 diabetes). Youth with type 1 diabetes were less physically active (Cohen’s d = − 0.23, 95%CI − 0.42 to − 0.04), more sedentary (Cohen’s d = 0.33, 95%CI 0.06 to 0.61), and had lower cardiorespiratory fitness (Cohen’s d = − 0.52, 95%CI − 0.73 to − 0.31) than their healthy peers. This corresponds to –12.72 min/day of moderate-tovigorous physical activity, 63.3 min/day of sedentary time (accelerometry) and –4.07 ml/kg/min of maximum/peak oxygen consumption. In addition, young people with type 1 diabetes were less likely to meet the international physical activity recommendations than their healthy peers (odds ratio = 0.44, 95%CI 0.31 to 0.62). Conclusions: Keeping in mind the heterogeneity between studies in the design, population and assessment, our findings show that children and adolescents with type 1 diabetes seem to be less active, more sedentary, and have lower cardiorespiratory fitness levels than their healthy peers.Publication Open Access Association of physical activity patterns with nocturnal hypoglycemia events in youth with type 1 diabetes(Oxford University Press, 2024-07-02) Hormazábal Aguayo, Ignacio; Huerta Uribe, Nidia; Muñoz Pardeza, Jacinto; Ezzatvar, Yasmin; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ciencias de la Salud; Osasun ZientziakAims This study sought to elucidate the interactions among physical activity (PA) patterns, mean glucose concentrations, and the incidence of nocturnal hypoglycemia events in children and adolescents with type 1 diabetes, examining the moderating influence of daily dosage on these associations.Methods Eighty-two participants aged 6 to 18 years (43.9% girls) from the Diactive-1 Cohort Study, diagnosed with type 1 diabetes, were included. Data collection involved continuous glucose monitoring, accelerometry to assess real-world PA, as well as documentation of daily insulin doses and carbohydrate counting over the same 7 days.Results A total of 19 participants experienced at least 1 nocturnal hypoglycemia event over a span of 574 measurement days (106 days with and 451 days without nocturnal hypoglycemia). Higher levels of vigorous PA (VPA) were associated with lower same-day mean glucose levels (P = .014). Additionally, higher levels of moderate PA (P = .023), VPA (P = .011), and moderate-to-vigorous PA (P = .010) were associated with a greater number of nocturnal hypoglycemia events. Specifically, a significant association was identified between VPA and nocturnal hypoglycemia events when the daily insulin dose was at or above 1.04 units per kilogram of body weight per day (P = .016).Conclusion Daily VPA is associated with glucose reductions, potentially leading to more hypoglycemic episodes, particularly when there is an excess of daily insulin. This highlights the need for careful insulin management in children and adolescents with type 1 diabetes engaging in VPA.
