NCT ID: NCT05953194 Completed - Obesity Clinical Trials

Effects of Sugary Drinks Counter-marketing Messages

Start date: August 7, 2023
Phase: N/A
Study type: Interventional

This study aims to examine consumer responses to traditional and counter-marketing messages discouraging sugary drink consumption, including effects on intentions to consume sugary drinks and perceived weight stigma. Because prior research has suggested that counter-marketing may be especially effective among younger populations, the investigators will examine effects overall and by age group (young adults [ages 18-29 years] vs. middle and older adults [ages 30+ years]).

NCT ID: NCT05845827 Completed - Pediatric ALL Clinical Trials

Dietary Impact on Continuous Glucose Monitoring

Start date: June 20, 2023
Phase:
Study type: Observational

Cardiorespiratory fitness (CRF), also known as "exercise capacity", is the capacity of respiratory and circulatory systems to supply oxygen to skeletal muscle during exercise for the generation of energy. Determinants of CRF include lung capacity, capillary density, cardiac output, hemoglobin concentration, and mitochondrial function. The research group studies how CRF is related to fuel utilization, yielding a mechanistic understanding of the association between lower CRF and worsening metabolic health via mitochondrial function. The objective of this study is to measure fuel utilization in response to habitual diet for one week in adolescents and young adults, ages 14-22 years (n=30). Fuel utilization will be estimated by glucose measures using a continuous glucose monitor (CGM). Habitual dietary intake will be collected via a mobile phone application (BiteAI, Inc) that uses artificial intelligence to extract nutrient information from food photographs. Participants will undergo two standard of care (SOC) meal tolerance tests at home - a glucose tolerance test and a Ensure® mixed meal tolerance test. CRF will be estimated by measuring maximum oxygen consumption (VO2 max) during a graded treadmill test. The hypothesis is that a higher VO2 max will be associated with increased fuel utilization, measured by lower glucose response to the SOC meal tolerance tests. The proposed study is described in the following aims: SPECIFIC AIM 1. Test for feasibility of completion of self-report dietary food records, completion of two at home meal tolerance tests that are standard of care for metabolic health screening, and completion of a seven-day continuous glucose monitor. SPECIFIC AIM 2. Identify nutrients and foods that are associated with an elevated glucose response. SPECIFIC AIM 3. Assess the influence of VO2 max on the glucose response to the SOC glucose tolerance test and Ensure® mixed meal tolerance test.

Development of Online Store for Testing Regulatory Food and Nutrition Policies in Brazil

Start date: May 24, 2023
Phase: N/A
Study type: Interventional

The purpose of this randomized controlled trial is to assess the impact of different nutrient profiles for magnifying glass front-of-package labels (FOPLs) on consumer choices in an online grocery store. Participants will be adults residing in Brazil recruited through a survey research firm. Participants will be randomly assigned to one of three shopping environments in an online grocery store. Participants will complete a shopping task (selecting items from a pre-specified shopping list) in the online grocery store. After completing the shopping task, participants will be rerouted to a computer survey. The survey will include standard behavior and label perception questions, as well as demographic items.

NCT ID: NCT05776329 Completed - Obesity Clinical Trials

Dietary Intervention to Reduce Metabolic Endotoxemia

Start date: April 14, 2023
Phase: N/A
Study type: Interventional

The goal of this randomized clinical trial is to compare an antiinflammatory and environmentally friendly dietary strategy (AIA-D) designed based on the planetary health diet recommendations translated to the regional context and including nutrients related to antiinflammatory responses with an active control diet based on general healthy diet recommendations (CONV-D) in adults from 18 to 50 years of age with obesity (body mass index ≥30 kg/m2). The main questions it aims to answer are: - If the intervention with AIA-D will cause a significant decrease at the end of the intervention (six weeks) in lipopolysaccharide-binding protein (LBP) compared to CONV-D. - If intervention with AIA-D will cause a significant increase at the end of the intervention (six weeks) in the relative abundance of two specific bacteria genera (AM and FP) when compared to CONV-D. Participants will: - Sign the informed consent. - Provide two peripheral blood samples (taken by our trained professionals). - Provide two samples of feces. - Allow anthropometric (body weight, height, hip and waist circumferences) blood pressure measurements on two occasions. - Respond to 24 h dietary recall on two occasions. - Attend the 1-hour group sessions requested (three for AIA-D and one for CONV-D). - Follow the dietary recommendations provided. - Be willing to participate in social media groups to receive information and follow up during the six weeks of the intervention. Researchers will compare an antiinflammatory and environmentally friendly strategy (AIA-D) with an active control diet (CONV-D) based on general healthy diet recommendations to see if AIA-D decreases metabolic endotoxemia measured through LBP serum levels and increase the relative abundance of AM and FP, compared to CONV-D.

NCT ID: NCT05658757 Completed - Blood Pressure Clinical Trials

Preliminary Effect of Food Processing and Sweeteners on Glycemic and Metabolic Measures

Start date: November 9, 2022
Phase: N/A
Study type: Interventional

The average adult in the US consumes over 1/3 of a cup of sugar each day, or nearly 300 calories worth, with the primary sources being from beverages, desserts and sweet snacks, candy, additions to beverages, and foods such as breakfast cereals. This is a risky health behavior, as high added sugar intake relates to higher risk of gaining weight, blood sugar disorders such as type 2 diabetes, plus heart disease and various cancers. Thus, high added sugar intake is problematic, and something in need of reducing. Therefore, the investigators are proposing to test how commercial foods sweetened with a new, FDA approved rare sugar with net zero calories (allulose), that is derived from dried fruits, brown sugar, and maple syrup may impact added sugar intake and usual blood sugar levels. The investigators are doing this by a randomized trial, in which the investigators will recruit participants with abnormal blood sugars (prediabetes or diabetes) or higher metabolic risk (bigger waist and elevated blood pressure or blood cholesterol) and ask them in random order to include foods in their usual dietary intake that are sweetened by regular sugars (regular sugar), foods that are sweetened by the zero calorie rare sugar allulose (low added sugar), or low added sugar intake by higher intake of fresh fruits and minimally processed and sweetened foods in place of usual sweetened foods. The investigators will measure their usual blood sugar levels for each of these 3 different 2- week periods with a blood glucose monitor, along with what they eat each of those periods, their blood pressure, and how the different dietary approaches impact how they feel.

NCT ID: NCT05502445 Completed - Sarcopenia Clinical Trials

The Nutritionist's Educational Intervention on the Protein Intake in Hospitalized Elderly People

Start date: September 1, 2021
Phase: N/A
Study type: Interventional

The food intake is often compromised in the elderly, and during hospitalization, dietary restrictions may be imposed, making them more susceptible to the risk of malnutrition and sarcopenia. It is essential to make an early identification of the elderly with low intake and involve them in their self-care. The aims will be assess the influence of the nutritionist's educational action to increase protein intake in elderly patients, to analyze the knowledge on its importance in the prevention of sarcopenia and to identify the prevalence of nutritional risk. This is a field, prospective, correlational, comparative and randomized study. The elderly patients will be randomized into a Control Group and Intervention Group.

NCT ID: NCT05424471 Completed - Obesity Clinical Trials

Preventing Early Childhood Obesity, Part 1: Long-term Follow-up

PECO1-LTF
Start date: May 1, 2021
Phase: N/A
Study type: Interventional

This study extends follow up on of Native American (NA) mothers and their children (now age 3-5 years) enrolled in the 1:1 randomized controlled trial of the Family Spirit Nurture (FSN) intervention designed to prevent early childhood obesity (PECO 1). The investigators will examine whether positive FSN impacts on sugar sweetened beverage (SSB) consumption and healthy growth in the first year of life were sustained. The investigators will also examine the effects of the emergency COVID-19 water solutions on water insecurity, early childhood SSB consumption, and growth, and explore how COVID-19 affected child feeding patterns and weight status either through changes in maternal mental health or household food access.
