Objective: Obesity in children is a serious public health concern. Technology-based games that incorporate physical activity and nutrition education create an opportunity to engage youth to promote healthy behavior change to help address the obesity problem. ''MyPlate Picks'' (MPP) is a new digital educational exergame designed to facilitate movement, provide knowledge, enhance motivation, and encourage behavior change related to healthy eating and physical activity in youth. This article describes the development, formative work, and initial evaluation of the feasibility, acceptability, and preliminary outcomes. Materials and Methods: Development and formative testing was conducted. MPP focuses on physical activity and three ''MyPlate'' nutrition education areas: ''make half your plate fruits and vegetables''; ''avoid oversized portions''; and ''drink water instead of sugary drinks''; and it provides opportunity for movement during gameplay. Two phases and multiple pilot groups of youth aged 7 to 13 years attending nutrition education programs (N = 48) were conducted by using single-group pre-post designs. The first phase (n = 21) examined individual and team gameplay, and the second phase (n = 27) focused only on team gameplay. A self-report survey included questions on knowledge, acceptability, and behavioral intention. Knowledge scores from gameplay logs were also examined for the individual gameplay group. Results: Across pilots, youth showed a mean increase of 11.8% on the knowledge survey. In-game knowledge scores in the individual gameplay group also showed a 12.5% increase in knowledge scores. Examination of post-gameplay behavioral intentions found strong reported intentions to eat more fruits and vegetables and get more physical activity. Majority of the youth reported that the game was a lot of fun. Conclusions: The formative work and initial evaluation of MPP shows promising results for knowledge and behavioral intentions. The youth reported that the team play approach was more fun. Future evaluation is needed to examine the game in larger groups and by using other implementation approaches.

Purpose The recent and rapid growth of social networking site (SNS) use presents a unique public health opportunity to develop effective strategies for the recruitment of hard-to-reach participants for cancer research studies. This survey investigated childhood cancer survivors’ reported use of SNS such as facebook or MySpace and their perceptions of using SNS, for recruitment into survivorship research. Methods Sixty White, Black and Hispanic, adult childhood cancer survivors (range 18 – 48 years of age) that were randomly selected from a larger childhood cancer study, the Chicago Healthy Living Study (CHLS), participated in this pilot survey. Telephone surveys were conducted to understand current SNS activity and attitudes towards using SNS as a cancer research recruitment tool. Results Seventy percent of participants reported SNS usage of which 80% were at least weekly users and 79 % reported positive attitudes towards the use of SNS as a recruitment tool for survivorship research. Conclusions and implications for cancer survivors The results of this pilot study revealed that SNS use was high and regular among the childhood cancer survivors sampled. Most had positive attitudes towards using SNS for recruitment of research. The results of this pilot survey suggest that SNS may offer an alternative approach for recruitment of childhood cancer survivors into research.
