Added-Sugars Warning Label PSAs

The purpose of this study is to determine if exposure to language-matched English-Spanish public service announcements (PSAs) can increase the understanding of and response to added-sugars menu warning labels among U.S. Hispanic adults. The hypothesis is that the experimental PSAs educating consumers about a new added-sugars menu label will significantly improve understanding of the label and reduce grams of added sugars in meals ordered from menus displaying the label. Participants will be recruited and randomized to one of two arms: (1) Control Arm: Viewing PSAs stating that using a phone while driving is dangerous or (2) Intervention Arm: Viewing PSAs informing participants about new added-sugars menu labels. Within the intervention arm, participants will be randomized to view one of three PSA themes.

A School-Based Nutrition and Fitness Program: Operation ToneUp

The goal of this clinical trial is to learn if a school-based intervention, Operation ToneUp, can improve nutrition knowledge, fitness, and blood pressure in schoolchildren enrolled in grades 3-6. The main questions it aims to answer are: 1. Do students participating in the intervention show improved fitness, measured by upper body strength, core strength, and cardiovascular endurance? 2. Do students participating in the intervention show improved nutrition knowledge, measured by self-report? 3. Do students participating in the intervention show improved blood pressure, measured by blood pressure cuff? Researchers will compare students participating in the intervention to students at comparison schools to see if fitness, nutrition knowledge, and blood pressure differ. Participants in the intervention arm will complete two 20-minute web-based sessions focused on nutrition and fitness during class time. Participants in the comparison arm will not be exposed to Operation ToneUp. All participants will engage in pre- and post- testing including: * PE-teacher assessed push-ups, curl-ups, and PACER test * online self-reported nutrition knowledge assessments * nurse-recorded blood pressure

Effect of a Nutrition Education Intervention on Ultra-Processed Food Awareness and Consumption Among University Students

Ultra-processed foods are industrially formulated products that often contain high amounts of salt, sugar, and saturated fat, as well as additives. Higher consumption of these foods has been associated with several chronic diseases. Medical students may be at increased risk of unhealthy dietary behaviors and food insecurity. This study aims to evaluate the effects of a low-cost nutrition education program on medical students' knowledge and attitudes about ultra-processed foods, ultra-processed food consumption, nutrition label literacy, and nutrition self-efficacy. A total of 74 sixth-year medical students at Eskisehir Osmangazi University Faculty of Medicine will be assigned by clusters to either an intervention group or a control group. The intervention group will participate in an educational program about ultra-processed foods, food labels, and healthier food choices. The control group will not receive this educational program during the study period. Data will be collected at baseline, immediately after the intervention, and at the one-month follow-up. The study will assess food security, knowledge and attitudes regarding ultra-processed foods, ultra-processed food consumption, nutrition label literacy, nutrition self-efficacy, and dietary intake based on three-day food records.
