Publication Open Access Development and validation of a scale measuring perceived barriers to physical activity in Spanish for children and adolescents with type 1 diabetes: the Physical Activity Barriers Scale for pediatric type 1 diabetes (PABS-1) questionnaire(Elsevier, 2025-06-01) García Hermoso, Antonio; Huerta Uribe, Nidia; Hormazábal Aguayo, Ignacio; Muñoz Pardeza, Jacinto; Chueca-Guindulain, María J.; Burillo Sánchez, Elisabeth; Ezzatvar, Yasmin; López Gil, José Francisco; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaAims: To develop and validate the psychometric properties, reliability, and criterion validity of the Physical Activity Barriers Scale for pediatric type 1 diabetes (PABS-1) in Spanish-speaking children and adolescents with type 1 diabetes. Method: A cross-sectional study was conducted with a sample of 93 Spanish-speaking children and adolescents with type 1 diabetes. The PABS-1 questionnaire was developed by experts and refined with patient feedback. Its validity was assessed by comparing results with accelerometer data, linking scores to objective physical activity measures. Results: The PABS-1 showed good internal consistency, with a Cronbach’s alpha (α) coefficient of 0.89, indicating strong reliability. Confirmatory factor analysis supported a four-factor structure, with physical, diabetes-related, psychological, and environmental barriers showing good fit indices (comparative fit index [CFA] = 0.94, root mean square error of [RMSEA] = 0.06, standardized root mean square residual [SRMR] = 0.05). Although the associations were small, the total PABS-1 score was significantly negatively correlated with cardiorespiratory fitness (Spearman’s rho [ρ]= -0.15, p = 0.035) and moderate-to-vigorous physical activity (ρ = − 0.12, p = 0.039). Among the four factors, motivational barriers exhibited the strongest associations with physical activity and fitness, showing significant negative correlations. Conclusions: The PABS-1 is a valid and reliable tool for assessing perceived barriers to physical activity in Spanish-speaking children and adolescents with type 1 diabetes.Publication Open Access Is fear of hypoglycemia a major barrier to an active lifestyle in children and adolescents with type 1 diabetes? The Diactive-1 study(Wiley, 2023) Huerta Uribe, Nidia; Chueca-Guindulain, María J.; Berrade-Zubiri, Sara; Burillo Sánchez, Elisabeth; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaStudies on fear of hypoglycemia as a barrier to physical activity among youth with type 1 diabetes (T1D) have been limited and controversial, most of which used self-reported assessment. The aim of the study was to evaluate the relationship between fear of hypoglycemia and physical activity and glycemic metrics in children and adolescents with T1D. Seventy-four participants (6–18 years of age; 44.6% females) with T1D were included in the study. Physical activity was assessed through accelerometry on nine consecutive days, and blood glucose metrics were simultaneously tracked using continuous glucose monitoring (time-in-range and hypoglycemic events). A closed question was used to evaluate the avoidance of physical activity due to fear of hypoglycemia. Fifteen participants (20%) reported avoiding physical activity due to fear of hypoglycemia. The group reporting no fear of hypoglycemia showed lower total physical activity (−35.33min/day, 95% confidence interval [CI] (−77.57 to −1.47)) and light physical activity (−29.81min/day, 95% CI −64.01 to −2.75) and higher sedentary time (77.95min/day, 95% CI 26.46–136.87) per day compared with those with fear of hypoglycemia. No difference was found between those patients with fear of hypoglycemia in terms of meeting the recommendations of glycated hemoglobin, glucose coefficient of variation, and time-in-range when compared to those with no fear of hypoglycemia. In conclusion, children and adolescents with fear of hypoglycemia were more active, less sedentary, and had similar glycemic metrics to those without fear. Our results therefore suggest that fear of hypoglycemia may be less of a barrier to an active lifestyle than previously believed.
