In most developed countries, children’s use of digital media has increased significantly. Concerns about how screen time (ST) affects physical activity (PA), sleep patterns (SL), and overall health habits have prompted further exploration of these associations. This study examined ST, PA, and SL patterns in children aged 3–7 years living in an urban environment. A multicenter prospective cohort study was conducted using the Surveillance of Digital Media Habits in Early Childhood Questionnaire (SMALLQ^®). Parents of 243 children completed the questionnaire, providing data on their children’s ST, SL, and PA habits during weekdays and weekends. A series of ANOVA tests were performed to assess differences in weekday and weekend ST, PA, and SL across age groups and sexes, as well as to compare these results with UN recommendations. The findings revealed a non-significant trend in ST and a significant effect of age group on PA during both weekdays and weekends, as well as on weekend SL. No significant differences based on sex were observed. Additionally, the comparison indicated that 3–5-year-old preschool children exceeded the recommended ST during weekends, while 6–7-year-old first-grade elementary children failed to meet the PA recommendations. These results highlight the critical role of age-related changes in shaping PA and SL behaviors in young children, emphasizing the importance of targeted interventions to foster healthy habits in early childhood.

Introduction: Nowadays, obesity is one of the main causes of death and disability. In recent years, it has been shown that the excess and distribution of body fat increases morbidity, with excess visceral fat being the most important factor that triggers pathologies. Thus, estimation of visceral fat makes it possible to identify patients with a higher cardiovascular risk, aiding the management of obesity. The main objective of the study was to identify predictors of the visceral fat index through a lifestyle intervention and to observe the effect of the intervention on dietary habits and functional capacity. Methods: A randomized intervention, parallel-group study was made. This study included 97 obese and overweight people (control group, n = 48; experimental group, n = 49) with a low socioeconomic status in an 8-month lifestyle intervention. Anthropometric, fitness and nutritional tests were assessed. Results: It was found that being female, eating the recommended daily portions of fruit, gaining strength in the legs and gaining flexibility are factors predictive of a lower visceral fat index. Age over 45 years and eating the recommended weekly portions of cereals and meats, fat and processed meats increases the visceral fat index after a lifestyle intervention. There were changes in the visceral fat index and in the different physical condition variables, but not in eating habits. Conclusion: A multicomponent lifestyle intervention reduces the visceral fat index; age over 45 and consuming cereals and meat increases the visceral fat index.

La autoliberación miofascial puede facilitar la disminución o desaparición del dolor intenso percibido por las terminaciones nerviosas localizadas en el tejido miofascial. Según algunos investigadores, la fibromialgia (FM) puede estar directamente relacionado con la teoría de la "sensibilización central". El presente estudio tiene como objetivo determinar la efectividad de la aplicación de un programa de autoacondicionamiento miofascial sobre el dolor, la depresión, la ansiedad y la calidad del sueño en personas diagnosticadas con fibromialgia (FM). La muestra se asignó al azar a los grupos de intervención (n =33) y control (n =33). Los sujetos del grupo intervención participaron en un programa de autoacondicionamiento miofascial compuesto por un total de 40 sesiones de 50 minutos cada una de ellas. Se tomaron medidas pre y post intervención. Los resultados se obtuvieron mediante un ANOVA 2x2 de medidas repetidas con dos factores (tiempo y grupo). Los resultados muestran que, después de completar el programa, los sujetos del grupo intervención obtuvieron una disminución significativa en el dolor general (p <0,01), el nivel de depresión (p <0,05), la ansiedad-estado (p <0,01) y rasgo (p <0,01), así como en tres subescalas relacionadas con la calidad del sueño, como son la "calidad subjetiva del sueño" (p <0,05), la "eficiencia habitual del sueño" (p <0,05) y la "disfunción diaria ”(p <0,001). Estos resultados indican que participar en un programa de autoacondicionamiento miofascial regularmente, bajo el control de un profesional de educación física y deporte, puede afectar positivamente a los pacientes con FM tanto física como psicológicamente. Self-myofascial release can facilitate the diminution or disappearance of the intense pain perceived by the nerve endings located in the myofascial tissue. According to some researchers, fibromyalgia (FM) can be directly related to the "central sensitization" theory. The present study aims to determine the effectiveness of the application of a self-myofascial conditioning programme on pain, depression, anxiety, and quality of sleep in people diagnosed with Fibromyalgia (FM). The sample was randomly assigned to intervention (n = 33) and control groups (n = 33). Subjects in the intervention group took part in a self-myofascial conditioning programme, which consisted of 40 sessions of 50 minutes each. Pre and post-intervention measurements were taken. Results were obtained by a 2x2 ANOVA for repeated measures with two factors (time and group). Results show that, after completing the programme, subjects in the intervention group had seen a significant decrease in general pain (p < 0,01), level of depression (p < 0,05), state (p < 0,01) and trait anxiety (p < 0,01), as well as three subscales related to the quality of sleep, such as “sleep subjective quality” (p < 0,05), “habitual sleep efficiency” (p < 0,05) and “daily dysfunction” (p < 0,001). These results indicate that participating in a self-myofascial conditioning programme regularly and under the control of a physical education and sport professional can affect patients with FM positively both physically and psychologically.
