Formative work to design a digital learning self-assessment and feedback tool to prevent weight gain among college students.

OBJECTIVE: While colleges have implemented brief, tailored interventions for health-risk areas such as alcohol prevention, theoretically-guided digital learning offerings for weight gain prevention have lagged behind in programming and implementation. Thus, the objective was to design and usability test a weight gain prevention digital learning platform for college students with modules targeting key nutrition and physical activity behaviors. METHODS: Development occurred in iterative phases: formative research, descriptive normative data collection, prototype development, and usability testing. Formative research consisted of background work and survey administration to incoming and current freshmen. Prototype development was guided by theories of behavior change and cognitive processing, and consisted of brief assessment and feedback using written text, graphs, and videos. Iterative usability testing was conducted. RESULTS: Current freshmen reported eating more quick order meals per week than incoming freshman, but fewer high-fat snacks and fewer sugary beverages. Current freshmen reported more sedentary time than incoming freshmen. Based on iterative testing results, eight behavioral targets were established: breakfast, high-fat snacks, fried foods, sugary beverages, fruit/vegetables, physical activity, pizza intake, and sedentary behavior. Initial usability testers indicated the modules were easy to understand, held their attention, and were somewhat novel. Analysis of qualitative feedback revealed themes related to content, layout, structure and suggested refinements to the modules. CONCLUSIONS: A gap exists for evidence-based obesity prevention programs targeted to adolescents as they transition into adulthood. Brief, tailored digital learning interventions show promise towards addressing key behavioral nutrition and physical activity targets among students during the transition to college.

Young adult e-cigarette users: perceptions of stress, body image, and weight control.

OBJECTIVE: With the rise in electronic cigarette (ENDS) use among US young adults, more research is needed on expectations for use and perceptions related to body image, weight control, and stress relief. METHODS: College students (N = 230; modal age 21 years; 68% female) completed an online survey assessing cigarette smoking and ENDS, dieting and body image, perceptions about flavors, stress, weight gain prevention, and appetite regulation. SAMPLE CHARACTERISTICS: Dual use (cigarette and ENDS) was reported by n = 69 (30.0%). Exclusive cigarette smoking was endorsed by n = 53 (23%) with exclusive ENDS use reported by n = 15 (6.5%). Ninety-three participants (40.5%) reported not using either product. RESULTS: Among those using ENDS, < 33% reported using as a stress management tool, < 15% reported using ENDS to control appetite, and > 70% reported using cartridges that tasked like sweets. There was a positive correlation between dieting behaviors and body concern, suggesting those who reported higher use of ENDS for weight and appetite regulation also had higher pathological eating scores and concern over body shape and size. CONCLUSION: Prevention and education related to weight, body image, and tobacco are needed to address misperceptions of tobacco products. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.
