IMPROVING FRUIT AND VEGETABLE INTAKES

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 通过社区环境和/或国家临床站点网络进行癌症预防试验需要制定适当的干预措施。一个很有前途的行为策略是制定实施意图，它非常容易管理。这种干预的前提是，一旦人们制定了行动计划，自动行为就会随之而来。在初级保健中使用这种干预措施是一种创新的方法，可以用最少的工作人员时间来诱导预防行为。这项研究的目标是通过减少营养较低的食物的摄入量，在不改变整体能量摄入量的情况下，每天增加2份水果和蔬菜的摄入量。食物的替代对于预防体重增加至关重要。这项可行性研究旨在进行一项随机对照临床试验，以测试单独或通过电话支持制定实施意图是否可以在不增加整体能量摄入的情况下增加水果和蔬菜的消费。在密歇根州伊普西兰蒂的一个家庭医学诊所的招聘成功将被记录下来，重点是少数民族的参与程度。饮食评估将是主要的结果变量。其他评估将包括人口统计学、干预目标行为的自我评估和血浆中类胡萝卜素的水平。我们将招募105名受试者，每组保留28名受试者，并且在三个研究组中检测水果和蔬菜摄入量的微小差异的能力良好。这将为设计更大的饮食干预试验产生有用的数据，这些试验具有成本效益，并将利用多个临床站点来优化招募。'

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The conduct of cancer prevention trials through community settings and/or national networks of clinical sites requires the development of appropriate interventions. One promising behavioral strategy that is very simple to administer is that of the formulation of implementation intentions. The premise of this intervention is that once persons formulate a plan of action, automatic behavior follows. Use of this intervention in primary care is an innovative approach to eliciting preventive behaviors with minimal staff time. The goal in this study will be to increase fruit and vegetable consumption by 2 servings/day without a change in overall energy intakes by decreasing consumption of a less nutritious food. Substitution of foods is critical for prevention of weight gain. This feasibility study aims conduct a randomized, controlled clinical trial to test whether formulation of implementation intentions, either alone or with telephone support, can increase fruit and vegetable consumption without an increase in overall energy intakes. Recruitment success in a family medicine clinic in Ypsilanti Michigan will be documented with emphasis on the extent of minority participation. Dietary assessment will be the main outcome variable. Other assessments will include demographics, self-assessment of behaviors targeted by the intervention and levels of carotenoids in plasma. We will enroll 105 subjects to retain 28/arm, and power is good to detect small differences in fruit and vegetable intakes among the three study arms. This will generate useful data for the design of larger dietary intervention trials that are cost-effective and which will utilize multiple clinical sites to optimize enrollment.'
