Background-Weight-related problems are prevalent in adolescent girls.

Background Young adults are at risk for weight gain. Little is known about how to design weight control programs to meet the needs of young adults and few theory-based interventions have been evaluated in a randomized control trial. The Choosing Healthy Options in College Environments and Settings (CHOICES) study was funded to create a technology-based program for 2-year community college students to help prevent unhealthy weight gain. The purpose of this paper is to: 1) provide a brief background on weight-related interventions in young adults; 2) describe the study design for the CHOICES study, the conceptual model guiding the research and the CHOICES intervention; and 3) discuss implications of this research for health educators. Translation to Health Education Practice Our experiences from the CHOICES study will be useful in suggesting other theory-based models and intervention strategies that might be helpful in programs attempting to prevent unhealthy weight gain in young adults. In addition, this paper discusses important considerations for working with 2-year colleges on this type of health promotion work.

This study examined the feasibility of implementing an innovative theater-based after-school program, 'Ready. Set. ACTION!', to reach ethnically diverse and low-income children and their parents with obesity prevention messages. The study population included 96 children and 61 parents. Children were in fourth to sixth grade and 41% were overweight at baseline. Program impact was evaluated with a pre/post-randomized controlled study design, but a major focus was placed on the process evaluation conducted in the intervention schools. Intervention children and parents reported high program satisfaction and that they had made changes or intended to make positive changes in their behaviors due to program participation. However, few meaningful differences between the intervention and control conditions were found at follow-up. Thus, the combined process and impact evaluation results suggest that the intervention was effective in leading to increased awareness of the need for behavioral change, but was not powerful enough on its own to lead to behavioral change. From this feasibility study, we concluded that Ready. Set. ACTION! offers promise as a creative intervention strategy. The next research step may be to incorporate theater-based programs into more comprehensive school-based interventions, with both educational and environmental components, and evaluate program impact.

Our objective was to conduct a process evaluation of the CHOICES (Choosing Healthy Options in College Environments and Settings) study, a large, randomized, controlled trial designed to prevent unhealthy weight gain in young adults (aged 18-35) attending 2-year community colleges in the USA. The 24-month intervention consisted of participation in an academic course and a social networking and support website. Among intervention participants, completion rates for most course activities were >80%, reflecting a high level of dose received. Course retention and participant satisfaction were also high. Engagement results, however, were mixed with less than half of participants in the online and hybrid sections of the course reporting that they interacted with course materials ≥3 h/week, but 50-75% reporting that they completed required lessons 'all/very thoroughly'. Engagement in the website activities was also mixed with more than half of intervention participants logging onto the website during the first month, but then declining to 25-40% during the following 23 months of the intervention. Intervention engagement is a challenge of online interventions and a challenge of working with the young adult age group in general. Additional research is needed to explore strategies to support engagement among this population, particularly for relatively long intervention durations.

Young adults are at risk for weight gain in the transition to independent adulthood; 2-year college students are at greater risk and understudied relative to 4-year students. This project conducted formative research for a randomized controlled weight gain prevention trial among 2-year college students, to ensure appropriateness of content and delivery of a curriculum originally developed for 4-year college students. Data were collected from community college students, faculty, and staff from October 2009 to August 2011. Work included focus groups and key informant interviews, curriculum pilot testing, and social network and support website beta testing. Based on focus groups and interviews, program content, course delivery modes, and communication channels were adjusted to meet population interests and preferences. The course was delivered successfully in pilot testing, and the website was received well by beta testers. Formative work successfully guided program adaptations to address population needs.
