Filter by:The study will test a model of biobehavioral mechanisms involved in the development of a system of emotion, attachment, and nutritive intake in the mother-infant dyad and the association of this system with maternal feeding behavior, child eating behavior, dietary intake, and adiposity. To participate in this study the infant must also be enrolled in long-term observational study, NCT06039878.
The goal of this interventional study is to measure the blood levels of the gut hormones LEAP2 and acyl ghrelin (AG), appetite and food intake after consuming liquid meals of different caloric sizes, in healthy adults with and without obesity. AG is a stomach-derived homone that increases appetite, and LEAP2 a liver-gut derived hormone that decreases appetite, which interferes the action of AG ant its receptor in the brain called the growth hormone secretagogue receptor (GHSR). Blood levels of AG and LEAP2 change in opposite directions after food intake (AG decreasing, LEAP2 increasing). AG is formed from an inactive version of hormone called desacyl ghrelin (DAG). Previous studies have shown that greater food intake leads to a greater decrease in blood levels of total ghrelin (AG + DAG), but this has not been studied for changes in blood AG or LEAP2 after eating. Blood levels of AG and total ghrelin when fasted and after food intake are lower, while blood levels of LEAP2 are higher, in adults with than those without obesity. The main study questions are: 1. Are there greater increases in blood levels of LEAP2 and greater decreases in blood levels of AG after consuming larger meals (by amount of calories they contain)? 2. Are greater decreases in appetite after connsuming larger meals related to greater increases in blood levels of LEAP2 and greater decreases in blood levels of AG? 3. Are greater decreases in food intake at a buffet lunch after consuming larger meals eaten a few hours previously related to greater increases in blood levels of LEAP2 and greater decreases in blood levels of AG? 4. Do the above findings differ between adults without obesity and with obesity? Healthy adults (without and with obesity) will consume liquid meals containing different amounts of calories (0, 600, 1200, 1800 kcal, of identical total volume) after an overnight fast and have measurements of blood LEAP2 and AG and appetite ratings from 0 to 180 min, and have food intake at a buffet lunch measured at 180 mins.
Bariatric surgery is the most effective treatment for severe obesity, yet a significant percentage of patients achieve suboptimal results or present long-term weight regain. Given the strong association between poor outcomes and post-surgery psychological factors, it is crucial to implement post-surgical psychological interventions. This randomized controlled trial aims to compare the efficacy of a novel, cost-effective, and timely-personalized treatment delivering strategy (stepped-care) with two different intensities 1) low-intensity intervention delivered by Facebook®, and 2) high-intensity program delivered online. It is also intended to study predictors, outcome moderators/mediators, and the underlying mechanisms of weight regain. Participants' assessment will include measures of pathological eating behavior, psychological impairment, negative urgency, and emotional regulation.
In post-menopause, most women gain weight, and obesity rates are more prevalent in this particular group. In addition, there is an increased risk of cardiovascular disease, cancer, and diabetes. Given that this weight gain can be related to risk behaviours, healthy weight management (such as an increase in physical activity or healthy eating) is crucial to promote a healthy weight and well-being. The ME-WEL (MEnopause and WEigth Loss) project (ref. SFRH/BD/144525/2019), entails an eHealth intervention for weight management and well-being in post-menopausal women with overweight or obesity, based on two theoretical models of behavioral change - the Health Action Process Approach (HAPA), and the Health Belief Model (HBM), and applying the Behaviour Change Techniques Taxonomy (BCTT). This group's eHealth intervention lasts 8 weeks. Each week there is a different theme to be addressed, taking into account the behavioral change models mechanisms, in articulation with different BCT´s. Subjective well-being, self-esteem, weight loss, implementation of weight management strategies, and changes in eating behavior and physical activity/exercise were evaluated, through follow-ups at 3- and 6- post-intervention.
The goal of this study is to learn about how children's sleep is related to their eating behaviors the next day, and to learn about factors that relate to eating behaviors and sleep health that are specific to preadolescent children living in rural communities.
In recent years, the planetary health diet proposed by the EAT-Lancet Commission has underscored the importance of massive changes to healthy eating on a global scale to prevent environmental degradation. Diet management helps individuals control their food consumption, and this can be supported by the availability of technology through mobile applications. The use of mobile applications considers several aspects such as convenience, comfort, and self-management efficiency in maintaining food consumption. By using an application with the latest features related to diet management, which is equipped with dietary education features, gas emissions, and calculating environmental impacts, it allows users to increase self-awareness to reduce gas emissions from food consumption. Therefore, developing recommendations for a balanced nutritional diet, healthy lifestyle, calculating diet quality, and greenhouse gas emission in one application that is presented in one easy step is an important point in providing comprehensive information for a wider range of potential users. The main objective of this study is to assess the differences in changes in body weight, BMI, waist circumference, and systolic and diastolic blood pressure between the group that was given education on a planetary health diet with calorie restriction and a healthy lifestyle and the group that received education on a balanced diet with calorie restriction and a healthy lifestyle in adults using the 3rd generation of EatsUp mobile application. We will conduct a 24-week intervention for overweight and obese adults.
The goal of this clinical trial is to examine the impact of price decreases based on energy content in a full-service restaurant on immediate dietary consumption (in terms of kilocalories (kcals), sugar, fat, and salt intake) and dietary consumption the rest of the day following the intervention; and whether the intervention effects differ based on socioeconomic position (SEP). Participants will be asked to visit the restaurant twice. At visit 1, participants will receive a control study menu with the existing pricing structure of the restaurant. At visit 2, participants will receive the same study menu with the pricing intervention introduced. For comparative purposes a smaller subgroup of participants will receive the control menu at both visit 1 and 2 to allow the researchers to estimate whether any pre-post changes occur in the absence of a pricing intervention (and whether change differs by SEP).
Body dissatisfaction is most common among girls in their teenage years and young adulthood, this is also around the time where the risk of developing binge eating disorder is the highest. Black/African American girls are more likely to engage in binge eating behaviors compared to their White American counterparts; however, they receive less help for eating issues. Further, increase rates of obesity in the Black/African American population may indicate that binge eating may be a bigger problem for this population than discussed. Therefore, the primary purpose of this randomized controlled pilot is to assess the feasibility of this pilot study to be used in a large scale fully-powered study. The secondary purpose of this study is to assess if two different nutrition and body image programs elicit positive outcomes among Black/African American teenage girls who indicate a desire to improve body image.
The goal of this feasibility study is to get insight into the receptivity of a JITAI aimed at healthy dietary intake in inhabitants of a small city in the Netherlands. The main question it aims to answer is: • what is the right time and the right location to send notifications to people and for what type of interventions are people most receptive? Furthermore, the aim is to get insight into the relevance and usability of the app, the privacy concerns that people have and the perceived effectiveness of the app on dietary intake. Participants will test our app for 2 weeks, of which they will receive prompts during one week.
The pilot study will test the feasibility of a 16-week sleep extension intervention, in adults with obesity, to increase nighttime sleep duration, as well as reduce daytime sleepiness and sleep-related disturbance. The study will also examine changes in weight, eating behaviors, wellbeing, and blood pressure across the 16-week intervention .
