43 Clinical Trials for Various Conditions
The goal of this randomized controlled trial is to test the effect of time-restricted eating (14-hour fast, 10-hour eating window) of a low-energy dense diet (reduced calories per gram of food) in older adults with obesity and insulin resistance. The study aims to determine if modulating the energy density of the diet reduces: 1. Insulin resistance and 2. Body weight. Researchers will compare the groups: 1. Following time-restricted eating and given a diet reduced in energy density or 2. Following time-restricted eating and given a diet typically consumed in this population
The purpose of the study is to determine whether the energy density of snack foods affects the amounts that preschool children serve themselves and then consume. We will serve snacks that vary in energy density to preschool children in their childcare centers and measure the amount they serve themselves and consume. The results will have implications for guidance about the provision of snacks for preschool children and may help in identifying strategies for the prevention of obesity in children.
The purpose of this study is to gain a better understanding of how energy density and cognitive framing of satiation using food information can influence consumption at a meal. This study also aims to investigate the influence of energy density and food information on sensory specific satiety (the decline in the subjective pleasantness of a food as it is eaten).
The investigators previous studies have shown that obese and non-obese individuals respond differently to daily intake of snack food. The purpose of this study was to determine whether these differences are specific to high energy density snack foods. The investigators hypothesized that obese individuals would show an increase in motivation to obtain high energy density snack foods after two weeks of daily consumption, but that non-obese women and obese women consuming low energy density foods would have reduced motivation to consume snack foods after two weeks of daily consumption.
In this study, the investigators will vary the energy density of foods served during three 5-day periods. There will be a baseline condition, and then a condition where the energy density of food is lower and a condition where the energy density of food is higher. The primary aim is to determine the effect of varying the energy density of foods served over 5 days on energy intake in preschool children. It is hypothesized that mean daily energy intake will be greater when children are served higher energy dense foods over 5 days than when served lower energy dense foods over the same period. Additionally, it is hypothesized that daily energy intake in the conditions with higher and lower energy densities will begin to converge across the 5-day period.
In this study, the investigators varied both the energy density and portion size of milk served with a meal commonly consumed by preschool children. The milk used in this study is commercially available and reflects typical variations in energy density. The primary aim of the study is to investigate the independent and combined effects of milk energy density and portion size on preschool children's intake of the milk and the simultaneously served meal. The effect of milk energy density and portion size on children's total energy intake at the meal will also be evaluated.
This study investigates the effect of varying both energy density and portion size of all foods at lunch on preschool children's intake. The foods used in this study are commercially-available, commonly-consumed foods with typical variations in energy density. The primary aim of the study is to investigate the independent and combined effects of energy density and portion size on preschool children's intake at a meal composed of foods typically served to this population.
The purpose of this research is to determine whether varying the energy density and portion size of the main course will affect meal energy intake after consumption of a first course that has previously been shown to enhance satiety. It is hypothesized that increasing either the energy density or portion size of the main course will increase meal energy intake after consumption of the first course. It is also hypothesized that compared to when a first course is consumed, not consuming a first course will increase meal energy intake.
The purpose of this research is to investigate how using different methods to reduce the energy density of entrees affects daily energy intake in adults. It is hypothesized that reducing the energy density of entrees will decrease energy intake. It is also hypothesized that reducing the energy density by incorporating fruit and vegetables will decrease energy intake more than reducing the energy density by decreasing fat content or adding plain water.
This study will examine the independent and combined effects of energy density and eating rate on appetite and endocrine mediators of appetite. Increasing eating rate and energy intake are expected to additively increase energy intake.
Pre-portioned entrées are commonly consumed to help control portion size and limit energy intake. Few studies, however, have investigated the influence of the characteristics of pre-portioned entrées on energy intake. This study investigates how the characteristics of solid pre-portioned entrées, specifically, variations in their energy content and energy density influence energy intake over a day. The investigators hypothesize that reducing the energy content and energy density of compulsory entrées will act independently and add together to reduce daily energy intake.
The purpose of this research is to investigate children's responses to incorporating vegetables into selected entrees and snacks over several days. The hypothesis is that children will increase their vegetable intake by consuming foods that have been reduced in energy density through the addition of vegetables. Effects on energy intake will also be examined.
This study will test the hypothesis that incorporating vegetables into meals as a method of reducing the energy density will result in increased vegetable intake and decreased energy intake.
A pilot study was conducted to develop the study menus that were similar in appearance, aroma, and taste.
This study investigates the effect of a low energy-density dietary prescription as compared to MyPlate recommendations in preschool children at risk for obesity.
This study will investigate the energy consumed from an entree with high- or low-volume vegetables incorporated into the entree or served along side of the entree, in normal weight adults.
As individuals tend to eat a constant weight or volume of food, manipulating physical and energy densities generally results in changes in energy intake without affecting subjective appetite sensations. However, relatively few studies have directly studied the interaction between physical and energy density manipulation. This study will determine the effects of foods that systematically vary in physical and energy density on ad libitum energy intake and subjective appetite ratings. Secondary outcomes will include gastrointestinal discomfort, fatigue and acceptability.
For weight loss to occur, energy intake needs to be reduced to incur an energy deficit. One dietary strategy that may facilitate weight loss is consuming a diet low in dietary energy density (ED). It is hypothesized that a diet low in ED, which can be achieved by a high intake of low-ED foods, low intake of high-ED foods, or a combination of the two, will allow a greater amount of volume of food to be consumed relative to energy consumed, which can assist with reducing energy intake. To understand how best to lower the ED of the diet, it is important to understand the relationship between low-ED and high-ED foods. Behavioral economics is a framework that provides a foundation to understand that eating behaviors can be substitutes for each other. Substitute eating behaviors are two behaviors that change in the opposite direction of each other (i.e. one behavior increases as the other behavior decreases). If low-ED and high-ED foods are substitutes for each other, in situations in which low-ED food intake increases, high-ED food should automatically decrease, and vice versa. If they are not substitutes, when low-ED food intake increases, high-ED food intake should remain unchanged, and when high-ED food intake decreases, low-ED food intake should remain unchanged. When low-Ed and high-ED foods are not substitutes for each other, purposeful change in intake for both low- and high-ED foods need to occur to best lower dietary ED. Thus, the purpose of this study is to investigate if low-ED foods and high-ED foods substitute for each other. Healthy weight adults will be served a meal over 4 sessions, with each meal containing 5 different food items. The foods in the meal will vary in ED: low-ED = 0 to 1.0 kcal/kg; medium-ED = 1.1 to 2.9 kcal/kg; high-ED = \> 3.0 kcal/g. For the 4 sessions, the meals will include: 1) 3 low-ED foods, 0 medium-ED foods, 2 high-ED foods; 2) 3 low-ED foods, 1 medium-ED food, 1 high-ED food; 3) 1 low-ED food, 2-medium ED foods, 2 high-ED foods; and 4) 1 low-ED food, 3 medium-ED foods, and 1 high-ED food.
The investigators will conduct a 2x2 factorial randomized controlled trial to test the separate and synergistic effects of an in-person hands-on dietary and physical activity change curriculum (i.e., Mi Vida Saludable program) and e-communication strategies (text messaging, emailed newsletters and an interactive website) on changing dietary and physical activity behaviors among a diverse population of Latina breast cancer survivors who have completed breast cancer treatment. Participants will be evenly randomized to 4 arms: in-person education alone, e-communication alone, in-person education plus e-communication, or control.
Foundations for Health is a 12-week behavioral weight loss interventions primarily conducted via the internet aimed at helping overweight and obese young adults (ages 18-30) lose weight by increasing physical activity, decreasing the energy density of the diet, and increasing consumption of low energy dense self-made meals by providing culinary training skills.
The purpose of this investigation is to conduct a 12-week pilot study to examine the effect of three different dietary prescriptions that differ on targeting reducing energy density (kcal/gram) and energy (kcal) on overall dietary intake, hunger, feelings of deprivation, satisfaction with the diet, mood, and weight loss in 45 overweight/obese adults receiving a 12-week behavioral weight loss intervention.
The purpose of this randomized controlled study using a crossover design is to investigate the main effect of portion size and food type (low-energy dense vs. high-energy dense) on caloric intake.
After a three month weight loss phase involving the use of meal replacements, participants are randomized into different weight loss maintenance conditions. Aim 1: To test the hypothesis that the meal replacement (MR) and reduced energy density eating (REDE) interventions, when added separately to the LEARN program, will produce superior weight loss maintenance compared to a LEARN-only intervention. Aim 2: To test the hypothesis that the weight loss maintenance condition that combines MRs and REDE will produce better maintenance of weight losses than either individual component and than the LEARN-only condition. Aim 3: To test the hypothesis that the two conditions receiving the REDE intervention will experience longer-lasting improvements in the energy density and nutritional composition of the diet compared to the two non-REDE conditions.
This study will test the hypothesis that reducing the energy density of the diet by incorporating more water-rich foods will result in: 1) greater weight loss and weight maintenance; 2) greater diet satisfaction and satiety; and 3) more healthful dietary patterns than reducing dietary fat alone.
The objective of the proposed work is to determine whether administration for 12 months of romosozumab followed by 12 months of denosumab will maintain bone mass at the knee in subjects with subacute SCI compared to 24 months of denosumab administration alone.
Current radiologic imaging modalities used in dentistry provide information on the morphology of the hard tissues. Additional information on the density of bone has practical relevance, for example, in dental implant treatment planning, where local bone quality is a known strong predictor of successful implant osseointegration. The Dual-Energy Cone Beam Computed Tomography (DE-CBCT) device is designed to overcome limitations of traditional imaging and will provide assessment of jaw bone density in additional to morphological information. This clinical trial will examine the application of DE-CBCT to assess jaw bone density and compare Hounsfield units (HU) values with multidetector CT, an established standard for assessing BD.
Sponsor is conducting this post-market study to evaluate the clinical outcome and femoral bone mineral density (BMD) changes associated with the PROFEMUR® PRESERVE hip stem when used as indicated for primary total hip arthroplasty in patients with osteoarthritis of the hip joint.
The purpose of this study is to evaluate any change from baseline in bone mineral density (BMD) in subjects following the switch from a triple antiretroviral therapy (ART) regimen containing Tenofovir disoproxil fumarate (TDF) to the nucleoside reverse transcriptase inhibitor (NRTI) - sparing two - drug regimen of dolutegravir (DTG) + rilpivirine (RPV) in subjects participating in the parent studies 201636 and 201637 (SWORD-1 and SWORD-2). This open-label, parallel group, study is a sub-study which will recruit subjects who are receiving ART regimens which include TDF at the time of randomization to receive treatment in one of two identical parent studies 201636 and 201637 (SWORD-1 and SWORD-2). These are Phase III, randomised, open-label, multicentre, parallel-group, non-inferiority studies evaluating the efficacy, safety, and tolerability of switching to DTG plus RPV from current integrase inhibitor (INI)-, non NNRTI-, or protease inhibitor (PI)-based antiretroviral regimen in HIV-1-infected adults who are virologically suppressed, having HIV-1 ribonucleic acid (RNA) levels \<50 copies per millilitre (c/mL). Randomisation in the parent studies will be stratified by baseline third agent class (INI, NNRTI, or PI), age group (\< or =\>50 years old) and participation in this Dual energy X-ray absorptiometry (DEXA) sub-study, therefore there will also be balance across the treatment arms in this sub-study both overall and with respect to baseline third agent class and age at entry. The study population will include approximately 75 evaluable subjects recruited from the Early Switch DTG + RPV treatment group of the parent studies 201636 and 201637, and approximately 75 evaluable subjects from the Late Switch group who continue their current antiretroviral therapy (CAR) through to Week 52 across both the 201636 and 201637 (SWORD-1 and SWORD-2) studies. Subjects participating in study 202094 will have DEXA scans performed at Day 1 and at study Weeks 48, 100 and 148 in parallel with the corresponding scheduled visits in the parent studies.
The purpose of this study is to determine whether consuming calcium carbonate that has been micronized is more effective than the traditional form of calcium carbonate in maintaining or increasing bone mineral density in people who are currently taking bisphosphonates or other bone-health medications.
This study compares the change (loss) of bone mineral density (BMD) that occurs in the proximal femur after hip resurfacing and total hip replacement.
