Filter by:The global obesity epidemic presents an unprecedented challenge to the public health worldwide. The factors associated with obesity are complex, and include health behaviours, such as eating habits and daily physical activity, and broader social, environmental and biological determinants that influence these health behaviours. The intestinal microbiota has several beneficial functions related to host health and accumulating evidence indicates that the gut microbiota plays a significant role in the development of obesity, obesity-associated inflammation and insulin resistance. Differences in community composition, functional genes and metabolic activities of the gut microbiota appear to distinguish lean vs obese individuals, suggesting that gut 'dysbiosis' contributes to the development of obesity and/or its complications. Recent studies have suggested some beneficial effects of probiotics and/or prebiotics on obesity and metabolic syndrome in adults; such experience is limited in children and adolescents. There are limited information about the synbiotics in children and adolescent with obesity.The mechanism of action of probotics on obesity are scarce and microbiota restoration/reshaping might be the one. The objective of this study tested the effects of a multispecies synbiotic on anthropometric measurement, glucose metabolism, lipid parameters and intestinal microbiota in children with exogenous obesity.
Obesity is associated with functional decline , altered spatiotemporal gait parameters (e.g. lower gait speed, shorter strides, and increased step width), and a significantly higher metabolic cost of walking compared to people with normal body weight. Obesity also negatively affects balance control.This study will investigate foot progression angle in adolescents related to their weight and category classification based on the CDC (Centers for Disease Control and Prevention) growth charts.
The main objective of this research project is to assess the impact of the timing of exercise on sensory perception, more specifically on taste and smell. Also, the investigators want to identify the optimal exercise timing scenario that maximizes the short-term anorexigenic effect of exercise (i.e. decrease in energy intake at the meal following the exercise session) in each group of teenagers. Hypothesis: exercise immediately before a meal (EX->MEAL) will be the most efficient scenario, and will show a larger impact on males individuals and people who suffer obesity. Subsequently, the investigators want to understand the impacts of exercise on lifestyle habits (i.e. sleep and sedentariness). For the realization of this research project, the investigators plan to recruit approximately 144 participants, boys and girls with normal weight/obesity, aged 12 to 17 years. Of these participants, half will be male. There are two different exercise timings (i.e. performed at 9:30 am and 11:00 am using a treadmill to test the maximal aerobic capacity) and one sedentary control condition. Participants will take part in 3 experimental visits in a random order (~5 hours/visit at LAPS-UdeM + 24h of real-life monitoring). Appetite sensations, energy intake (i.e. total and macronutrient), activity monitoring using actigraphy, hormonal (i.e. anorexigenic and orexigenic) and chemosensory (i.e. cortical response to taste and smell stimulations) response will be monitored in the laboratory and/or remotely. This project will measure acute response in laboratory and real-life settings.
The purpose of this study is to evaluate how food commercials influence food choices in children and their parents.
The investigators aim to undertake a feasibility randomised controlled trial (RCT) to investigate whether mHealth technology, allowing biometric informed feedback and coaching on exercise and PA, can be incorporated into the existing Liverpool Overweight and Obesity Programme (LOOP) at Alder Hey Children's Hospital. The overall objective is to have an evidence-based exercise and PA intervention ready to evaluate in a future RCT.
Obesity can be defined as' a disease that occurs as a result of the energy (calorie) taken with food being more than the energy consumed and the excess energy being stored as fat in the body, negatively affecting the quality and duration of life. BMI is calculated by dividing the weight (kg) by the square of the height (m2) (1,2). According to the World Health Organization (WHO) classification, BMI between 25-29.9 kg / m2 is overweight, 30-34.9 kg / m2 is light, 35-39.9 kg / m2 is medium, 40 kg / m2 and above is considered as severe obesity. Obesity has important effects on respiratory function. These mechanical and biochemical effects are not easily measured by pulmonary function test and BMI measurement.Changes caused by mediators produced by adipose tissue likely cause changes in lung function, but this effect is not fully understood at the moment. The aim of our study is to make these effects more understandable and to compare them with different obesity classes and people with normal weight who are considered healthy. Hypothesis 0: The effects of obesity on respiratory functions and multidimensional health-related parameters do not show a statistically significant difference compared to individuals with different levels of the disease and normal weight individuals classified as healthy. Hypothesis 1: The effects of obesity on respiratory functions and multidimensional health-related parameters show a statistically significant difference compared to people with different levels of the disease and normal weight individuals classified as healthy. The study will be carried out by face-to-face evaluations in a clinical setting with obese patients between the ages of 18-65 who have applied to the clinic with a diagnosis of obesity and agree to participate in the study, and healthy volunteers who are considered to be healthy without a diagnosis of obesity. Looking at the evaluations to be made; Measurement of respiratory function parameters, measurement of respiratory muscle strength, anthropometric measurements, evaluation of body composition, quality of life, upper extremity muscle strength and grip strength, lower extremity muscle strength, fatigue evaluation, vital signs, evaluation of exercise perception, presence of dyspnea and its level will be evaluated. A detailed description of these evaluations and the parameters to be used will be explained in detail in the next step.
Obesity affects 3%-4% of the pediatric population and leads to cardiac mortality during adult life. Bariatric surgery is the best treatment for weight loss and preventing obesity associated comorbidities in adults, but its applications and safety are yet to be defined for adolescents.
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.
This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in youths with obesity, ages 12-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (3 sprays per nostril, 4 times per day) for 12 weeks. Study visits include screening to determine eligibility, 2-part main study visits at baseline, week 8, and week 12, and safety check-in visits at weeks 1, and 4; phone calls at weeks 2, 6, and 10, with a safety follow-up visit 6 weeks after the last dose of study drug. Study procedures include appetite, behavioral, metabolic, and endocrine assessments.
Obesity is one of the most important health problems of developed and developing countries. Especially in children and adolescents, the prevalence of obesity is increasing at an alarming rate. In obese individuals, the effects of postural control and balance have been reported to cause musculoskeletal problems, and motor control skills have been found to decrease. The aim of this study is to compare the effects of balance exercises and strengthening exercises on balance, posture and lower extremity functions in obese adolescents.
