Clinical trials

The goal of this clinical trial is to learn if eating more beef will lead to better cognition and a healthier brain in younger adults. The main questions it aims to answer are: * Does eating more beef lead to higher scores on cognitive tests and better quality of life? * Does eating more beef lead to better brain function? Researchers will compare participants in the experimental group (participants who will eat 25 ounces of beef every week during the dietary intervention) to control participants (participants who will eat 5 ounces of beef every week during the dietary intervention). Participants will: * Be instructed to prepare and consume ready-to-eat beef meals along with their regular diet and not eat any more beef other than what they are given * Visit the study facilities once every week to pick up ready-to-eat beef meals; and complete a brief survey every week to track their consumption of the provided beef meals, and a dietary survey every 4 weeks * Visit the study facilities before and after the 12-week of intervention period for researchers to study them

The goal of this clinical trial is to compare the impact of providing participants with 1. A recently developed protocol for motivating bystanders to intervene to help others who are in sexual risk situations (Motivate-the-Bystander) alone 2. Motivate-the-Bystander with an alcohol component focused on reducing drinking behaviors (Motivate-the-Bystander+Alcohol) 3. A control condition focused on reducing stress The main questions it aims to answer are: * Is Motivate-the-Bystander more effective than the attention control for increasing bystander behaviors? * Is Motivate-the-Bystander+Alcohol more effective than MTB alone for increasing bystander behaviors? * Is Motivate-the-Bystander+Alcohol more effective than Motivate-the-Bystander alone for decreasing alcohol use during bystander intervention opportunities? Participants will: * Complete online measures (e.g., self-reported bystander behaviors, past bystander training, history of bystander intervention attempts, sexual experiences, drinking behaviors, and other substance use behaviors) * Complete either MTB, MTB+ALC, or the attention control condition online * Complete the virtual reality simulation in the lab * Complete electronic daily diary follow-up surveys about alcohol use and bystander intervention

The purpose of this study is to find out whether a program called "Healthy Children, Healthy Communities" can help young children in rural areas eat healthier and improve their health. The study focuses on children ages 3 to 5 who attend family childcare homes in rural communities. The main goal is to see if the program can: Help children eat healthier foods, like more fruits and vegetables. Support childcare providers in using positive mealtime practices that encourage healthy eating. The study will involve about 120 licensed family childcare providers in rural areas who participate in the Child and Adult Care Food Program (CACFP), along with about 240 children they care for. Childcare providers will be randomly placed into one of two groups: EAT Family Style Group (Intervention Group): Complete 7 online training modules over 16 weeks about healthy mealtime practices. Join 7 individual coaching sessions on Zoom. Record short videos of their mealtimes to get personalized feedback from a coach. Work with a coach to set goals and make plans to improve mealtimes. Receive printed materials and conversation cards to use during meals. Some providers may join Zoom interviews to share their experiences. Better Kid Care Group (Comparison Group): Complete 10 online modules about general childcare topics like child development, oral health, play, and managing a childcare home. For both groups, the research team will: Ask providers to fill out online surveys about how mealtimes work in their childcare homes. Visit the childcare homes to observe and record children's mealtimes on two days at each data collection point. Measure the height and weight of participating children. Use a painless skin scanner (Veggie Meter) to check how many fruits and vegetables children have been eating. Ask providers to complete surveys about the children's eating habits. The study focuses on rural, low-income communities, where children are at higher risk of having poor diets and obesity compared to children in urban areas. Information will be collected at the start of the study, after 16 weeks, and again after 24 weeks to see if there are lasting changes.
