40 Clinical Trials for Various Conditions
The goal of this study is to 1) use magnetic resonance imaging (MRI) to evaluate the effect of nutritious foods on inflammation in the human hypothalamus of children and 2) assess the feasibility and acceptability of nutritious food feeding intervention strategies in children with overweight or obesity.
Most individuals with obesity become so before age 35 and adolescent's unhealthy dietary patterns, specifically high intake of ultra-processed foods and poor overall diet quality, may contribute to energy overconsumption and weight gain. The overall objective of this research is to establish proof-of-concept for altered reward processing measured by brain response to ultra-processed foods, an increase in ad libitum energy intake, and adverse effects on executive function in response to an ultra-processed diet (81% total energy) compared to a diet emphasizing minimally processed foods in individuals aged 18-25 years.
There is an unmet need for nutrition interventions that address both autism spectrum disorder (ASD) specific feeding challenges and unbalanced eating habits among children with ASD to prevent future chronic health conditions. Children with ASD tend to consume few fruit and vegetables and mainly high-energy dense foods, including sugar-sweetened beverages and processed snacks. Obesity prevalence in children with ASD is up to 40% higher than in typically developing children, and recent studies show significantly elevated risks of hyperlipidemia and hypertension among individuals with ASD, regardless of using psychotropic medications. Our interdisciplinary team conducted a preliminary study to examine diet quality and mealtime behaviors among diverse children with ASD in Florida (34% Hispanic/Latino) and parental preferences for nutrition interventions. Based on the study findings, we developed the manual for our nutrition intervention, Autism Eats, for children with ASD enrolled in the Part C of Individuals with Disabilities Education Act (IDEA) Early Intervention (EI) services. Our Autism Eats manual and parent materials are based on ASD-specific feeding strategies such as food chaining combined with behaviorally-focused nutrition intervention strategies such as goal setting and weekly meal planning to promote healthy eating. Among children with ASD enrolled in Part C EI services in Florida, we will conduct a randomized controlled trial (RCT) with the nutrition intervention program, Autism Eats, and the enhanced usual care (EUC) comparison program. The Autism Eats intervention is to prevent problematic mealtime behaviors and promote development of healthy eating habits. We expect that implementing the Autism Eats will be feasible and the intervention will be well-received by EI providers and parent-child dyads. We will examine differences in children's food intakes (fruit and vegetables), food variety, diet quality, and problematic mealtime behaviors between children in Autism Eats and those in the EUC groups at post-intervention and 5-month follow-up from baseline.
The purpose of this study is to test the effectiveness of a new curriculum on toddlers' self-regulation skills and healthy eating habits. The curriculum is being delivered as part of Early Head Start home visits and compared to the effectiveness of usual practice Early Head Start home visits.
The purpose of this study is to determine whether a health education program incorporating sugar sweetened beverage and juice (SSB/J) reduction and home water delivery affects maternal and infant risk for obesity by randomizing mother-infant dyads to one of three 24-month interventions: Group 1 (control): standard health education program only; Group 2 (translation): health education program focused on sugar reduction; and Group 3 (efficacy): health education program focused on sugar reduction and bottled water delivery. The intervention program will be delivered by trained health educators during in-person home visits, or virtually via phone or video calls.
The purpose of this study is to modify the food culture of the fire service by motivating firefighters and their families to incorporate Mediterranean diet principles at work and home through behavior change strategies that involve education, participation and incentives. The ultimate purpose is to lower firefighters' risks for CVD and cancer by successfully getting more firefighters and their families to adopt and incorporate the healthy eating principles behind the Mediterranean diet.
RATIONALE: Decreasing the amount of fat in the diet and increasing fruit, vegetable, and fiber intake may help prevent some types of cancer. Giving participants easy-to-read personalized written nutrition materials and a personalized videotape may help improve eating habits. PURPOSE: This clinical trial is studying how well personalized nutrition education improves the eating habits of healthy participants who eat an unhealthy diet.
This is an open-label observational single-group clinical trial to study the efficacy of a commercial superfood blend and its effect on markers of well-being and improvement of long-term healthy eating habits.
The overall goal is to determine how a sleep extension intervention (increasing time in bed) in individuals who maintain less than 6.5 hours sleep per night affects their plasma ceramides and insulin sensitivity. Participants will undergo a randomized controlled trial, with sleep extension (intervention) and healthy lifestyle (control) groups. The sleep extension is designed to increase participant's time in bed by 2 hours per night. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
The overall goal is to examine the efficacy of a circadian intervention in people with overweight and obesity and habitual short sleep duration (HSSD). Participants will undergo a randomized controlled trial, with circadian intervention and control (healthy lifestyle) groups. The circadian intervention is designed to reduce nighttime light exposure and after-dinner snack food intake. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
This is a community randomized controlled trial to evaluate a civic engagement curriculum through which residents will identify barriers and facilitators to healthy eating and physical activity and then implement a project in their communities.
There are great disparities in the prevalence of obesity and chronic disease in different sociodemographic groups. US Hispanic adults, in particular, have a higher prevalence of obesity and chronic diseases than non-Hispanic whites. Population aging is also a major contributing factor to the high prevalence of chronic disease, and Hispanics already make up approximately 10% of the older population. Therefore, preventive measures are needed to reduce the burden of chronic disease risks for Hispanics. Current lifestyle interventions for weight management have been particularly ineffective in this population. The purpose of this pilot project is to develop a novel tailored lifestyle intervention for use by Hispanic older adults with obesity. The Healthy Weight for Living intervention has been validated among adults with mixed racial/ethnic backgrounds and has achieved clinically impactful weight-loss. Its design features make it particularly suitable for use in populations with low adherence to traditional interventions, including no requirement for daily food logging and no increase in physical activity. The final product of this project will be a culturally adapted prototype intervention in Hispanic older adults that accounts for cultural heterogeneity. This work has direct relevance to reducing health disparities and the burden of obesity-associated chronic disease in a particularly at-risk population.
The goals of this pilot study is to evaluate the safety and feasibility of time restricted feeding in an older adult population.
The purpose of this study is to refine, evaluate the feasibility, and to estimate the effect of the "healthy Living Study," a brief outpatient problem-solving intervention to promote healthy eating and activity habits in adolescents.
The purpose of this proposal is to launch the first trial of a single-session intervention (SSI) specifically for the prevention of eating disorders (EDs).
The purpose of this study is to test the feasibility and tolerability of donepezil in a small group of patients with anorexia nervosa (AN). Study participants will be receiving care at the New York State Psychiatric Institute Eating Disorders Unit. Study medication will be increased from 1 mg per day to a maximum of 5 mg per day for up to 8 weeks. Participants will be closely monitored for side effects by a research psychiatrist every week, in addition to the regular clinical monitoring they receive during inpatient treatment. The study will also include assessments of habit strength to measure any changes in maladaptive eating habits over the course of the treatment.
With funding from the United States Department of Agriculture (USDA), the Tufts University's Friedman School of Nutrition Science and Policy will be implementing a new, health and wellbeing program for Head Start educators at ABCD Head Start Centers in the greater Boston area. The purpose of this study is to evaluate the combined impact of a health and wellness program and behavior change guides. The evaluation will focus on ABCD Head Start educators as the study population. Tufts University's Friedman School of Nutrition Science and Policy is responsible for implementing and evaluating this new intervention through surveys and analysis of administrative (health and wellness App) data. A paper and pencil survey will be used to gather information on dietary, physical activity, and sleep behaviors. The surveys will also include a module on satisfaction with the health and wellness App and Guides. Survey data will be combined with the administrative data about App utilization.
The study will use a between-subjects design in a sample of individuals with BMI greater than or equal to 28 from the Los Angeles community (N=330). Participants will be randomly assigned to a weight stigma vs. control manipulation. Changes to the following health behaviors will be subsequently measured in their everyday lives: 3-day diet as captured by ecological momentary assessment (EMA) food diaries, objectively measured eating of obesogenic foods, objectively measured physical activity captured by 24-hour actigraphy, and sleep, captured objectively by overnight actigraphy and subjectively self-reported sleep measures. The investigators hypothesize that weight stigma causes decrements in health behaviors (e.g., sleep, eating, and physical activity) in everyday life.
There is strong reason to believe that sleep promotion during adolescence could yield long-term health rewards; the investigators' data show that, when they get more sleep, Morning Larks have impressively reduced intake of overall calories and foods high in glycemic load that are linked to long-term health risk. Before that can be translated into major public health interventions, however, the field needs to understand why similar changes in sleep had no effect, or even an adverse effect, on adolescent Night Owls. This experimental study will clarify why there have been such discrepant effects across Morning Larks and Night Owls, with the goal of more broadly harnessing the promise of improved sleep in the prevention of obesity and long-term morbidity.
This intervention aims to evaluate the efficacy of a pilot educational intervention with deep-structure cultural tailoring for Latino ethnic groups on diet quality compared to general, surface-level healthy-eating messages.
The purpose of this study is to learn more about what happens in the human body after consuming a meal that contains ultra-processed foods like hamburgers, and if this is different to what happens after consuming a meal that contains lots of whole foods, like fresh vegetables, instead.
Adopting a healthy eating pattern is important for meeting dietary recommendations and weight management. Although less clear, it seems reasonable to assume that the eating patterns we typically follow can also affect our psychological wellbeing. As such, healthy eating patterns are often adapted to suit one's personal preference. For example, many people choose to follow a vegetarian-style eating pattern whereby meat, poultry, and seafood are excluded from the diet. However, current research suggests that vegetarian eating patterns may result in decreased synthesis of new muscle proteins when compared to the typical meat-based US-style diet. This ultimately leads to reduced muscle quality and mass which increases the risk of dependence and mobility limitations later in life. Another important factor to consider when adapting a healthy eating pattern is the frequency and distribution of meals throughout the day. In the US, protein intake is typically skewed throughout the day such that people consume more protein at dinner when compared to breakfast. This skewed distribution combined with a low meal frequency (3 meals per day) can also sacrifice the rate of muscle protein synthesis. As such, it is important to investigate the interaction between food choices, meal frequency, and protein distribution to promote muscle health and prevent development of disease and disability. In addition, it is also important to understand how these eating patterns affect enjoyment and pleasure following meals. This work will help to determine healthy eating patterns that promote muscle health and psychological wellbeing.
The majority of female undergraduate students experience disordered eating and/or weight gain, increasing the risk for two serious public health problems, eating disorders and obesity. Traditional nutrition education about weight control delivered during college has not been effective and may even exacerbate these problems. Thus, the investigators propose that instead of focusing on external information as taught by nutrition education (e.g. 'calories in, calories out', quantification and cognitive processing of nutrition information), at-risk females be trained to become more attuned to their internal hunger and fullness signaling to set them on a trajectory for decreased chronic disease risk as they age.
College-aged women are at risk for eating disorders and disordered eating, which present serious health concerns. Two potent risk factors for eating disorders, body dissatisfaction and dietary restraint, are common among female college students. Intuitive eating is a strategy in which instead of listening to the predominant 'diet culture' and focusing on things like calories and energy balance, individuals practice listening to their internal physiological signals to decide when and what to eat and when to stop. Based on current research, intuitive eating has been shown to foster body satisfaction and healthy eating attitudes among women. The proposed pilot study will evaluate the feasibility and acceptability of an intuitive eating program for University of Delaware college women. In addition, this study will test the hypothesis that the intuitive eating program will reduce cognitive factors of body dissatisfaction and dietary restraint in females compared to a waitlisted group. Additionally, the investigators expect this reduction in dietary restraint to be associated with less disordered eating behavior. Exploratory aims include measuring engagement in disordered eating behaviors and changes in weight over the study period. This preliminary data will be used to estimate effect sizes for larger future trials.
The purpose of this pilot study is to test the feasibility and effectiveness of a mobile phone-based text messaging intervention to change the attitudes and eating behaviors of African American women residing in New Orleans, LA.
In this study, one year changes in healthy eating and gardening behaviors associated with the intervention were estimated using a group randomized controlled trial design, with the comparison arm receiving a delayed intervention in the following school year.
Food is widely understood as a cornerstone of health, however multiple barriers stand between well-intentioned, well-informed consumers and the adoption of healthier dietary practices. This mixed-methods randomized controlled trial (RCT) will measure the impact of offering a Community Sustained Agriculture (CSA) share as an employee benefit on household food environments (diets), eating behaviors, and lifestyles.
Background: Youth from low-income and minority families are disproportionately affected by obesity and its complications. This study presented pilot work to develop and implement a multi-component physical activity and healthy eating intervention at a Boys \& Girls Club (BGC) after school program. Methods: Using a community-based participatory approach, BGC staff and academic researchers developed intervention components informed by formative studies and based on a social ecological theory framework. Components included healthy eating and physical activity policy implementation, staff training, a challenge/self-monitoring program for healthy behaviors, a peer-coaching program for healthy behaviors, and a social marketing campaign. Preliminary intervention efficacy was assessed through a single group, pre-post study design with measured collected at baseline and 6 months.
This pilot study will be a randomized parallel trial comparing Mindfulness-Based Irritable Bowel Syndrome Eating Awareness Training done over an 8 week period to a standard low Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols diet.
Most of the nation's serious chronic health challenges and causes of death, including diabetes, heart disease, cancer, and obesity, are directly linked to sub-optimal diet. Both poor diets and associated disease are disproportionately common in the Appalachian counties of eastern Kentucky, a region with stark health inequities, including elevated rates of obesity, overweight, and premature mortality. The purpose of this pilot study is to evaluate a multi-component intervention developed through community-based participatory research methods for improving access to healthy foods and enhancing dietary intake in eastern Kentucky. The intervention components evaluated in this study consist of a social marketing campaign delivered to middle and high schools to promote healthy snacking and water consumption, and a series of group cooking classes for adults.
