The Centers for Disease Control and Prevention (CDC) recently reported that 16-33% of children and adolescents in the United States are overweight or obese, making this the number one nutritional disease of this group. The prevalence appears to be increasing annually, as are the associated consequences. Moreover, the CDC estimates that less than 50% of adolescents are physically active on a regular basis. In order to improve the health of these individuals, an intervention must be focused to modify these behaviors. Facilitating the understanding of proper nutrition and need for physical activity among adolescents will likely prevent health problems such as overweight and obesity and the development of chronic diseases later in life. Despite these concerns, adolescents remain one of the most underserved populations in terms of preventive services. In the past, health education interventions have shown increases in knowledge; however, the ultimate goal of these programs is to positively impact behavior. To accomplish this, we must focus on the learning styles of "today's" adolescents. Computer-based interventions allow for individualized strategies to promote healthy lifestyles. A computer-based intervention program has the potential to elicit a greater behavior change in comparison to a traditional didactic intervention program.
美国疾病控制与预防中心（CDC）最近报告称，美国16%至33%的儿童和青少年超重或肥胖，这使其成为该群体的头号营养疾病。其患病率似乎每年都在上升，相关后果也是如此。此外，疾病预防控制中心估计，定期进行体育锻炼的青少年不到50%。为了改善这些人的健康状况，必须集中进行干预以改变这些行为。促进青少年对适当营养和体育活动需求的理解，可能会预防诸如超重和肥胖以及日后生活中慢性病发展等健康问题。尽管存在这些问题，但在预防服务方面，青少年仍然是最缺乏服务的人群之一。过去，健康教育干预已显示出知识的增加；然而，这些项目的最终目标是对行为产生积极影响。要做到这一点，我们必须关注“当今”青少年的学习方式。基于计算机的干预措施允许采用个性化策略来促进健康的生活方式。与传统的讲授式干预项目相比，基于计算机的干预项目有可能引发更大的行为改变。
