REDUCING CANCER-RELATED DIETARY RISK BEHAVIORS IN ADOLES

全国营养调查表明，儿童和 青少年的饮食不符合推荐摄入量， 水果和蔬菜，并超过总能量的建议摄入量 胖了 这些饮食模式，是在童年时期学到的， 成年后，使我们的年轻人患某些类型癌症的风险增加， 包括乳腺癌、结肠癌和胃癌。 低收入人群 社会经济地位越高，这些癌症和其他癌症的发病率越高。 本研究建议推行一项为期两年、多元化的校本 计划针对多民族，较低的社会经济学生，他们的 家庭和学校环境，以增加学生水果的摄入量 和蔬菜，并减少从总脂肪中摄入的热量。 一 随机社区试验设计将采用20所学校从两个 市中心学区（明尼阿波利斯和圣保罗）被随机分配到 干预或延迟程序条件。 这些学校 招收了不成比例的大量明尼苏达州少数民族儿童， 来自低社会经济背景的儿童。 干预措施将 在1997-1998和1998-1999学年， 2004届毕业生已经上了六年级和七年级。 形成性 将进行评估，以确定信息和干预措施 文化上适当和相关的战略。 干预 组成部分将包括1）学校课程解决饮食线索， 广告对食品选择的影响和健康食品的障碍 选择; 2）家庭干预部分，旨在促进 学生与家长就饮食选择进行讨论， 认识家庭环境对青少年食物的影响 选择，并增加健康食品的选择在家里的可用性 以及3）学校环境部分，针对食物供应、食物线索 以及学校环境中与食物有关的激励措施。

DESCRIPTION: National nutritional surveys indicate that children and adolescents are eating a diet that does not meet recommended intakes of fruits and vegetables and exceeds recommended intake of energy from total fat. These dietary patterns, that are learned in childhood and track into adulthood, predispose our youth for increased risk of some types of cancer, including breast, colon and stomach cancer. Populations that are of lower socioeconomic status have higher incidence rates of these and other cancers. This study proposes to implement a two-year, multi-component school-based program targeting multi-ethnic, lower socioeconomic students, their families, and their school environment to increase student intake of fruits and vegetables and to reduce their intake of calories form total fat. A randomized community trial design will be employed with 20 schools from two inner-city school districts (Minneapolis and St. Paul) being randomized to either the intervention or the delayed-program condition. These schools enroll a disproportionately large number of Minnesota minority children and children from low socioeconomic backgrounds. Interventions will be implemented in the academic years 1997-1998 and 1998-1999 when students from the Class of 2004 are in their sixth and seventh grade. Formative evaluation will be conducted to determine messages and intervention strategies that are culturally appropriate and relevant. Intervention components will be comprised of 1) school curricula addressing eating cues, the influence of advertising on food choices and barriers to healthful food choices; 2) a home intervention component designed to facilitate student-parent discussions regarding dietary choices, increase parental awareness of the influence of the home environment on adolescent food choices, and increase the availability of healthful food choices in the home and 3) a school environment component targeting food availability, food cues and food-related incentives in the school environment.
