Background: Sickle Cell Disease (SCD) causes blood cells form a crescent shape. It is caused by a genetic mutation in the hemoglobin gene. People with SCD are at increased risk for illnesses like stroke, chronic pain, and heart problems, as well as decreased overall health and well-being. Researchers want to learn more about how nutrition and diet can help relieve or reduce the symptoms of SCD. Objective: To understand how diet, dietary patterns and behaviors, nutrition, and other related factors in adults with SCD affect their overall health. Eligibility: Adults aged 18 and older with SCD. Design: Participants will be screened with a review of their medical records. They will take a pregnancy test if needed. Participants will have a physical exam and medical history. Their height, weight, and waist and hip circumference will be measured. They can complete this exam (1) via telehealth along with a visit to an outpatient laboratory center or (2) by going to the NIH Clinical Center. Participants will complete 2 interviews about their diet. They will talk about the foods they ate in the past 24 hours. They will also complete 1 interview about diet-related behaviors such as food shopping and cooking. They can complete the interviews in person, by phone, or by telehealth visit. Participants will complete surveys about their demographics (such as age and gender), SCD pain, mood, stress, diet, and nutrition. It may take about 1 hour to complete all of the surveys. Participants will give blood and urine samples. They will need to fast for at least 8 hours overnight before giving blood samples. Participation will last for about 2 weeks.
Background: The risk of heart disease among African Americans is still common despite a greater understanding of the disease and better approaches to managing it. Healthy cooking and eating patterns can help reduce the risk of heart disease. But things like access to grocery stores and knowledge of good nutrition can affect these healthy patterns. Researchers want to see if community-based programs can help. Objective: To learn about the cooking behaviors of African American adults at risk for heart disease. Also, to see if a community-based cooking intervention will affect home-cooking behaviors. Eligibility: African American adults 18 and older who live in Wards 7 and 8 of Washington, D.C., and have at least one self-reported risk factor for heart disease Design: Phase I participants will complete a survey. It asks about their medical history, lifestyle, stress level, and eating habits. They will take part in a focus group. During this, they will talk about what they eat and what foods are available to them. Participation lasts 1 day for 3 hours at Pennsylvania Avenue Baptist Church in Washington, D.C. Phase II participants will go to shared cooking events at Pennsylvania Avenue Baptist Church. These will be held once a week for 6 weeks. They will be led by a trained chef. Participants will visit the NIH Clinical Center 3 times. Transportation will be provided if they need it. They will have physical exams and have blood drawn. They will be interviewed and complete questionnaires. A dietician will review the food they eat. An occupational therapist will assess their cooking skills. They will keep a daily cooking journal. Participation lasts 18 weeks. ...
This pilot clinical trial studies how well an evidence-based exercise and nutrition program adapted for Latinas works in improving physical activity and dietary behavior in non-active, overweight, or obese rural Latinas. An exercise and nutrition program may reduce the risk for developing certain cancers, obesity, and chronic health conditions in Latinas who are non-active, overweight, or obese.
The aim of this study is to compare a Web-based system and a computer telephone system to determine their effectiveness in improving diet behaviors compared to each other and a control group.
This research will focus on the effect of a 6-month behavioral intervention delivered via the World Wide Web that is aimed at increasing physical activity levels and decreasing dietary fat intake in a general population of adults. The study will be randomized and blinded. We are also planning to study subjects' compliance and retention rates when enrolled in a completely on-line study.
The purpose of this study is to examine the long term effects of a 24-week clinically-based behavioral nutrition intervention emphasizing the DASH diet compared to routine nutrition care on changing diet quality, blood pressure, hypertension status, and vascular function in adolescents with elevated blood pressure.
The purpose of this research is to improve our understanding of the effects that taking cholesterol reducing pills have on dietary behavior as well as other health related behaviors
The goal of this study is to determine the feasibility and acceptability of two food preference learning approaches for toddlers that could serve as alternatives to mere repeated exposure to new or previously disliked foods. The target population is toddlers who score higher on food fussiness. The study is a two-group randomized controlled trial. Families will be randomized to 1 of 2 study groups: associative conditioning, or the child tasting vegetables alongside a palatable dip, or modeling, in which the child and parent taste vegetables together. Both groups will attend two laboratory visits, one before and one after a 4-week exposure period, and will be asked to complete 8 vegetable tastings in accordance with their assigned condition across the 4 intervention weeks. Key questions to be addressed are: * summarizing the feasibility and acceptability of the intervention strategies * assessing whether children's liking and intake of the target food increase from baseline to post-intervention
The purpose of this study is to conduct a two site, three arm randomized intervention study to improve fruit and vegetable intake, improve whole grain intake and reduce sweetened beverages in young adults aged 21 to 30 years. This work is potentially very high impact in light of growing overweight and obesity and decreased health status overall, and potential dietary benefits to children of our target age group.
Lunch is in the Bag is an intervention designed to increase fruits, vegetables, and whole grains in sack lunches prepared for preschool children. Lunch is in the Bag includes 5 weeks of parent handouts, classroom activities related to topics in the handouts, parent and child activities to reinforce behavioral constructs, and a one week booster 22 weeks later. The primary study hypothesis is that Lunch is in the Bag will increase fruit, vegetables, and whole grains in sack lunches. Additional hypotheses are that lunches at child care centers where the program is used will have higher dietary quality than centers without the program and that children at the centers where the program is used will have a smaller increase in body mass index than children at centers with the program. The study will also look at the child's home environment and the childcare center. Hypotheses for this research question include 1. Children at centers with Lunch is in the Bag will have greater frequency of eating fruits, vegetables, and whole grains at home than those at centers without the program. 2. Compared to parents at centers without the program, parents of children at centers with Lunch is in the Bag will have 1. Greater knowledge, expected benefits, support, intentions, and belief in their ability for packing fruit, vegetables, and whole grain in their child's sack lunch daily. 2. Availability of fruit, vegetable, and whole grain in the home pantry. 3. Number of lunches with temperature in the safe range at time of service.
The goal of this study is to compare front-of-package labels to a no-label control and to one another: 1.) FDA's Nutrition Info with %DV, 2.) Nutrition Info with red "high", 3.) FDA's High In, 4.) multiple High In labels-one for each nutrient and 5.) a no-label control. Primary outcomes include 1.) correct identification of foods and beverages with the healthiest and least healthy overall nutrient profiles, 2.) perceived healthfulness of products low in two nutrients of concern, and 3.) correct identification of foods and beverages as high in saturated fat, sodium, and added sugars.
This study aims to compare different front-of-package label designs, using two schemes: (1) High In and (2) Nutrition Info with each scheme having (1) a version with colors (i.e., green, yellow, and/or red) indicating level of nutrient content and (2) a black-and-white version. Additionally the Nutrition Info scheme will have a version that includes the percent Daily Value in black and white. Labels will be compared against a no-label control and one another.
The goal of this randomized controlled trial is to test the effectiveness of a four-module nutrition education resource promoting nonpharmacological approaches to prevent and manage hypertension. The main questions it aims to answer are: * Does the educational intervention increase the knowledge of using nonpharmacological approaches in preventing and managing hypertension among participants? * Does the educational intervention improve participants' lifestyle behaviors to prevent and manage hypertension? Researchers will compare a four-module educational intervention with a control group (no educational information received until after the study) to see if the educational intervention works to improve knowledge and healthy lifestyle behaviors in preventing and managing hypertension. Participants will: * Attend a 30-minute workshop every week for 4 weeks or no workshop at all * Complete a survey on demographic information, knowledge, lifestyle behaviors, and quality of life at baseline and end of the study * Complete a dietary 24-hour food recall at baseline, two weeks into the study, and at the end of the study * Monitor blood pressure levels two times a day for four weeks
The objective of this research was to determine if adding a plate graphic depicting the components of the Eat Lancet Planetary Health diet (Figure 1) to food labels in Stanford University dining halls would lead to dining hall patrons making dietary decisions that better resemble the Planetary Health diet in comparison to a no signage control group. The study hypothesis was that presenting students with a plate graphic featuring the healthy reference diet would decrease objective measures of the amount of meat taken and therefore the environmental impact of student meals.
The purpose of this RCT is to examine the efficacy of the Group Lifestyle Balance (GLB) program adapted for people with stroke (CVA) on primary (weight) and secondary outcomes at 3, 6, 12 months from enrollment into the program.
The purpose of this study is to determine the efficacy of a community-based behavioral intervention (H2GO!) on decreasing sugar-sweetened beverage consumption and promoting water consumption among school-aged youth and parents/caregivers. We hypothesize that participants in the intervention site will demonstrate reduced sugar-sweetened beverage intake intake and increased water intake compared to participants in the comparison site at 2 and 6 months follow-up.
The purpose of this study is to use a community based participatory action research (CBPAR) approach to 1) create "radio stories" about Somali, Latino and Hmong families' real success stories with hypertension and obesity in managing their disease through implementation of healthful lifestyle behaviors (nutrition and physical activity), and 2) test the effectiveness and acceptability of radio stories on participant intentions to engage in or improve healthful lifestyle behaviors to prevent these disease. Participants in the Intervention condition listened to the "radio stories" and the participants in the control condition listened to an audio brochure with relevant health information. We hypothesized that the intervention participants would report higher intentions to engage in various healthful lifestyle behaviors than the control participants after both participants listened to their respective health information.
This study will examine children's eating behavior. The study will enroll approximately 400 participants (200 child/parent pairs). At certain time points, participants will engage in activities involving the presentation of food and the observation of behavioral responses to these presentations, as well as the completion of questionnaires
We hypothesize that in children with autism dietary antigens can change the intestine, making it "leaky" and then affecting the brain changing their behavior.
This study will determine whether a gluten- and casein-free diet has specific benefits for children with autism.
This phase I trial investigates how well a healthy eating program works in improving outcomes in patients with bladder cancer. The behavioral dietary program consists of educational materials, live phone calls, and interactive voice response phone messages. Participating in the healthy eating program may improve eating habits and/or reduce the risk of bladder cancer from coming back.
The study is a small pilot, designed to provide data regarding the feasibility and acceptability of conducting such a study on a larger scale. The present study is a randomized controlled clinical trial comparing two mindfulness-based lifestyle modification programs to help people manage diabetes and lose weight, one using on a low-carbohydrate diet (LC) and the other using a moderate-carbohydrate diet promoted by the American Diabetes Association (ADA). Intervention content will include information about nutrition (carbohydrate restriction or American Diabetes Association recommended diet) and emotion regulation and mindful eating strategies.
Obese individuals are at risk for developing cardiovascular disease (CVD). Increasing physical activity, losing weight, and reducing sodium intake may reverse arterial stiffness and blood vessel damage that is linked to obesity. This study will evaluate the effectiveness of a low sodium diet and a behavioral weight loss intervention in reducing arterial stiffness in overweight young adults.
Type 2 diabetes (T2D) is a national epidemic and current lifestyle programs and medications are not effectively managing the crisis. This project aims to test a novel smartphone-delivered intervention that simultaneously targets multiple health behaviors (i.e., sleep, sedentary behavior, physical activity,dietary intake) within clinical settings at a large Veteran Health Administration regional hospital. If effective, this project has potential for large-scale implementation nationwide through the VA healthcare system and broad applicability for other populations at T2D risk as well as other disorders.
A recent clinical trial demonstrated the efficacy of Gelesis100 use for weight loss (Obes 2019;27:205-216). The present trial is designed to explore the mechanisms by which it may work, i.e. by suppressing hunger, altering food intake and/or altering the efficiency of energy extraction from food.
RATIONALE: A low-fat, high-fiber diet that includes soy protein may prevent disease progression in patients with hormone-refractory prostate cancer. Nutrition counseling may help motivate patients to follow this diet. PURPOSE: Randomized phase I trial to study the effectiveness of behavior-based dietary interventions, such as receiving nutrition counseling, in helping patients who have hormone-refractory prostate cancer follow a low-fat, high-fiber, soy-supplemented diet.
to study the dietary intake and eating behaviors of adolescents who undergo bariatric surgery
The Aims of this study are 1) to develop a traditional plant-based diet that is palatable and acceptable to the Latino population and which contains the appropriate calorie and macronutrient composition needed to lose weight and improve metabolic function and; 2) to develop a culturally sensitive \[based on previous literature and stakeholder input\] lifestyle intervention program, that will be delivered by community health workers \[CHWs\], that focuses on consuming a traditional plant-based diet and overcoming the barriers to incorporating this dietary therapy as part of the family lifestyle but with a focus on the adult participant with obesity. Ultimately, in Aim 3 the investigators will conduct a 16-week randomized controlled trial (RCT) in 40 Latino adults with obesity \[20 control, 20 treatment\] to evaluate the intervention's: i) clinical efficacy; ii) fidelity of the implementation by CHWs; and iii) acceptance by CHWs and study participants.
Dietary intervention and other strategies to prevent unhealthy weight gain and the development of obesity should be based on knowledge of dietary, physiological, genetic and behavioral determinants and their contributing interactions. Identifying these determinants is difficult because physiological susceptibility to specific dietary and behavioral factors implicated in unhealthy weight gain differs between populations and individuals within the populations. The research challenge is identifying specific determinants in a free-living, adult population. Understanding the interaction between diet and the underlying susceptibility factors such as physiologic, genetic and epigenetic, and behavioral factors mandate an integrated approach. This integrated approach should include understanding the interplay of physiological factors (genetics, epigenetics, taste preferences, susceptibility to energy excess, etc.) and behavioral factors (food cravings, restraint, disinhibition, physical activity) as each of these domains is a potential driving force in energy expenditure, food preference, dietary choices, and food intake. Which of these factor(s) is most important? The investigators propose that by examining dietary, physiological, genetic, and behavioral factors in an integrated fashion we will gain insight into the obesity epidemic and identify the most important determinants of weight gain. As a secondary aim, the investigators will identify a single parsimonious collection of factors and develop strategies to mitigate the risks of developing obesity.
