RESUMO
Background: Excessive sedentary time has been negatively associated with several health outcomes, and physical activity alone does not seem to fully counteract these consequences. This panorama emphasizes the essential of sedentary time interruption programs. "The Up Project" seeks to assess the effectiveness of two interventions, one incorporating active breaks led by a professional and the other utilizing a computer application (self-led), of both equivalent duration and intensity. These interventions will be compared with a control group to evaluate their impact on physical activity levels, sedentary time, stress perception, occupational pain, and cardiometabolic risk factors among office workers. Methods: This quasi-experimental study includes 60 desk-based workers from universities and educational institutes in Valparaiso, Chile, assigned to three groups: (a) booster breaks led by professionals, (b) computer prompts that are unled, and (c) a control group. The intervention protocol for both experimental groups will last 12 weeks (only weekdays). The following measurements will be performed at baseline and post-intervention: cardiometabolic risk based on body composition (fat mass, fat-free mass, and bone mass evaluated by DXA), waist circumference, blood pressure, resting heart rate, and handgrip strength. Physical activity and sedentary time will be self-reported and device-based assessed using accelerometry. Questionnaires will be used to determine the perception of stress and occupational pain. Discussion: Governments worldwide are addressing health issues associated with sedentary behavior, particularly concerning individuals highly exposed to it, such as desk-based workers. Despite implementing certain strategies, there remains a noticeable gap in comprehensive research comparing diverse protocols. For instance, studies that contrast the outcomes of interventions led by professionals with those prompted by computers are scarce. This ongoing project is expected to contribute to evidence-based interventions targeting reduced perceived stress levels and enhancing desk-based employees' mental and physical well-being. The implications of these findings could have the capacity to lay the groundwork for future public health initiatives and government-funded programs.

INTRODUCTION: several public health programs are being implemented to combat childhood obesity in the world. However, the impact of Chilean Law n.o 20,606, which regulates the sale and advertising of foods high in critical nutrients ("Super 8 Law") about a critical period in the increase of body weight in schoolchildren, such as National Holiday (NH), has not yet been evaluated. OBJECTIVE: establish the effect of NH on various body composition indicators before and after the implementation of the Super 8 Law. METHODS: 110 schoolchildren between 10 and 13 years of age participated in this study, and 48 finished it after one year of follow-up (23 children and 25 girls). Body weight, body mass index (Zscore-BMI), triponderal mass index (TMI), fat mass index (FMI), percentage of fat mass and muscle mass during the four weeks of September 2015 (without law) and 2016 (with law). An ANOVA for repeated measures and adjusted for covariates was applied. RESULTS: body weight (0.327 and 0.556 kg), Zscore-BMI (0.057 and 0.085) and fat percentage (0.1 and 0.9%) increased significantly during both NH (without and with law, respectively). Compared to 2015, FMI and TMI do not show significant increases during 2016, however, there are no significant differences in any of the variables studied after the implementation of the law. CONCLUSION: despite observing slight advances in certain parameters of body composition between one year and another, the implementation of the Super 8 Law in Chile does not seem to generate a preventive effect during NH.
Introducción: diversos programas de salud pública están siendo implementados para combatir la obesidad infantil en el mundo. No obstante, el impacto de la Ley chilena n.o 20.606 que regula la venta y publicidad de alimentos altos en nutrientes críticos ("Ley Súper 8") sobre un periodo crítico en el aumento de peso corporal en escolares, como son las vacaciones de Fiestas Patrias (VFP) aún no ha sido evaluado.Objetivo: establecer el efecto de las VFP sobre diversos indicadores de composición corporal antes y después de la implementación de la Ley Súper 8.Metodología: participaron 110 escolares entre 10 y 13 años de edad y finalizaron 48 tras 1 año de seguimiento (23 niños y 25 niñas). Se evaluó el peso corporal, índice de masa corporal (Zscore-IMC), índice de masa triponderal (IMT), índice de masa grasa (IMG), porcentaje de masa grasa y masa muscular durante las 4 semanas del mes de septiembre de 2015 (sin ley) y de 2016 (con ley). Se aplicó un ANOVA para medidas repetidas y ajustada a covariables.Resultados: el peso corporal (0,327 y 0,556 kg), Zscore-IMC (0,057 y 0,085) y porcentaje de grasa (0,1 y 0,9%) aumentan significativamente durante ambas VFP (sin y con ley, respectivamente). En comparación a 2015, el IMG e IMT no muestran aumentos significativos durante 2016, sin embargo, no existen diferencias significativas en ninguna de las variables estudiadas tras la implementación de la ley.Conclusión: a pesar de observar ligeros avances en ciertos parámetros de composición corporal entre un año y otro, la implementación de la Ley Súper 8 en Chile no parece generar un efecto preventivo durante las VFP.
