Filter by:Overweight and obesity, understood as an accumulation of abnormal and excessive fat, are the second leading cause of preventable and avoidable mortality in developed countries, with more than 340 million children and adolescents affected by this disease worldwide. As a consequence, overweight and obesity at an early age is already considered a pandemic by the World Health Organization (WHO), with a high incidence in developed countries. The abuse of new technologies has remained at worrying levels in the post-COVID period, favoring an increase in the adolescent population considered sedentary. In this regard, up to 70% of adolescents show sedentary behaviors, especially affecting the time spent on screens by both males (93.8%) and females (87.2%). Thus, the use of the cell phone has been shown to be a determining factor, since between 10% and 16% of adolescents show a problematic use of this device, affecting, among other aspects, their behavior during their free time. In recent years there has been an increase in sedentary time among adolescents and a decrease in the practice of physical activity that has favored a greater accumulation of body fat and increased the probability of being overweight or obese. In this context, some studies have tried to encourage the practice of physical activity in the school context in overweight and obese population, being these interventions effective to improve body composition. However, these interventions also have their detractors, who argue that the hours of Physical Education are too limited to dedicate so much time to a single content, and that the pedagogical component is often overlooked in their implementation. As an alternative to the above, it has been suggested that Physical Education classes could be used to promote interventions that encourage adolescents to practice physical activity in their free time, and mobile applications could be used to monitor the activity carried out by adolescents, but also as an element that generates adherence and enjoyment in this population. Research in this population using these technologies is scarce, therefore, this project aims to determine the effectiveness of a ten-week intervention promoted from the subject of physical education in which a mobile application is used after school hours on physical activity, body composition and fitness in overweight or obese adolescents.
Metformin use for diabetes has the benefit of causing weight loss in some. The investigators in a preclinical trial, demonstrated that mice consuming non-nutritive sweetened (NNS) drinks had worse glucose improvements and weight loss than mice consuming sugar drinks or water. This study will conduct a pilot to determine if this translates into pediatric clinical practice. The hypothesis is that NNS drinks impair metformin-induced satiation, weight loss, and glucose tolerance.
The prevalence of obesity is one of the main public health problems worldwide, reaching 18% among young people between 5 and 19 years of age in 2016. One possibility of effective treatment can be the Mediterranean diet (MD). Therefore, it is proposed to carry out a nutritional intervention based on this diet to more effectively reduce obesity in adolescents. The main purpose of this multicentre study is to assess whether an energy-restricted Mediterranean-style diet (MD) intervention including healthy products from the Mediterranean basin (mixed nuts, pomegranate and hummus) and sourdough bread is more effective against obesity and associated CVD risk factors than a conventional low-fat diet carrying out a multicentre nutritional and clinical intervention study specifically targeting obese/overweight adolescents (13-17y) from different Mediterranean countries; all combined with an educational web-application designed to encourage healthy behaviours. It is a multicenter, randomized, controlled intervention study conducted with adolescents with obesity/overweight ≥90 percentile who do not suffer from any chronic disease. 240 subjects will be recruited from three Mediterranean countries: Italy (Parma), Portugal (Coimbra) and Spain (Reus), specifically 80 participants per country, 40 adolescents as an intervention group and 40 as a control group, in Reus. The intervention study is scheduled to begin in January 2021. The intervention group will receive a diet based on the characteristics of MD, and will be reinforced with satisfying and healthy Mediterranean foods such as sourdough bread (2 servings of 50-60g / day), squeezed pomegranate (4 servings of 200ml / week), hummus/chickpeas (2 portions of chickpeas of 150-200g / week, one in hummus format) and mixed nuts (4 servings of 30g / week); and the control group will receive a recommended diet based on the consumption of low-fat foods. A caloric restriction of 20% of the total energy requirements will be applied to both groups in adolescents with BMI ≥95 percentile (obesity) and a caloric restriction <20% of the total energy requirements will be applied in adolescents with BMI ≥90 to <95th percentile according to overweight (gender/age / physical activity). The diet will be applied for 4 months in both groups. Adolescents from both groups will be given a motivational interview and will be provided with an educational website that will be used during the intervention, through which they will learn.
The prevalence of adolescent behaviors that can lead to obesity are alarming, and reduced life expectancy is the future of America's youth if behavioral changes are not implemented to improve health and reduce the obesity burden. Researchers have argued that health literacy is a precursor to health knowledge and is necessary for translating knowledge about healthy choices into behavior, with low health literacy being associated with reduced preventive health behaviors in adults. Given the lack of health literacy-specific interventions addressing adolescents' obesogenic behaviors, the purpose of this study is to examine the preliminary effectiveness of adding a health literacy module to an obesity prevention intervention that addresses adolescents' obesogenic behaviors.
