Kids Cafe: Impact of a national feeding program on children's dietary behaviors

描述（由申请人提供）：肥胖是美国34%的成年人和17%的青年人的严重公共卫生问题，增加了某些形式癌症的风险。收入有限的人的肥胖和癌症发病率高于收入较高的人。事实上，肥胖占美国所有癌症相关死亡率的14-20%。因为青少年肥胖倾向于持续一生，所以保持能量平衡的努力应该开始在童年。青年肥胖症的日益流行可能会增加未来癌症的发病率。仅健康的饮食习惯，强调植物性食物（水果，蔬菜，全谷物和豆类）并保持健康体重的整体饮食模式，就可以将癌症死亡率降低30%。因此，为了降低肥胖和癌症的发病率，需要针对儿童及其饮食环境的创新干预策略。儿童营养计划（KCP）是一项为低收入儿童提供零食和营养教育的国家计划，但其有效性尚未得到评估。此R 03应用程序将评估KCP对儿童饮食行为和营养知识的影响。这部分研究将在研究的I期进行。在第二阶段，将制定KCP的家庭干预措施。将进行一项小型试点研究，以提供有关可行性、过程和干预结果的信息，包括饮食行为的变化，以及为后续R 01应用提供样本量计算信息的中介变量。这项研究将是对KCP改善饮食行为以预防肥胖和降低癌症风险的潜力的知识体系的独特贡献。调查结果将导致针对这一重要渠道的研究，以达到低收入家庭的健康促进干预措施。

DESCRIPTION (provided by applicant): Obesity, a serious public health problem for 34% of adults and 17% of youth in the United States, increases risk for some forms of cancer. Obesity and cancer rates are higher among individuals with limited income than those with higher incomes. In fact, obesity contributes to 14-20% of all cancer-related mortality in the US. Because youth obesity tends to continue throughout life, efforts to maintain energy balance should begin in childhood. The increasing prevalence of obesity in youth may increase future incidence of cancer. Healthy eating habits alone, with an overall dietary pattern that emphasizes plant foods (fruit, vegetables, whole grains, and beans) and maintains healthy weight, could reduce cancer mortality by as much as 30%. Thus, to reduce obesity and cancer rates, innovative intervention strategies are needed that target children and their dietary environments? Kids Cafi Program (KCP) is a national program that provides snacks and nutrition education for low-income children, but its effectiveness has not been evaluated. This R03 application will assess the impact of the KCP on children's dietary behaviors and nutrition knowledge. This part of the research will be carried out in Phase I of the study. In Phase II, the family intervention for KCP will be developed. A small pilot study will be conducted to provide information on feasibility, process and intervention outcomes, including changes in dietary behavior, and mediating variables to inform sample size calculations for a subsequent R01 application. This study will be a unique contribution to the body of knowledge regarding the potential for the KCP to improve dietary behaviors to prevent obesity and reduce cancer risk. Findings will lead to studies targeting this important channel to reach low-income families with health-promoting interventions.
