Eat Right for Long Life

描述（由研究者提供）：许多负面因素影响智力迟钝成年人的饮食习惯：家庭、工作、社区和电视上的不良榜样;鼓励不健康饮食习惯的环境;食物准备和自我宣传的技能有限;改变不健康饮食行为的激励很少。我们建议开发一系列教学模块，以提高这些人在以下领域的行为能力，自我效能和结果期望：在家多吃水果、果汁、蔬菜和低脂食品（FJV&LFF）（主要是零食），增加FJV&LFF的可用性和可获得性，增加他们对FJV&LFF的营养知识，扩大他们对这些食物的偏好，提高他们制作健康零食的技能，并增加他们在快餐店和便利店购买FJV和LFF。 第一阶段和第二阶段的主要目标是进行一项基于理论的干预的随机试验，以增加精神发育迟滞成人中FJV和LFF的消费。研究环境将是这些人居住的住宅设施。 研究将分两个阶段进行。在第一阶段，我们将修改和评估现有的食品评估工具，并制定和进行课程的第一个模块的可用性评估。

DESCRIPTION (provided by investigator): Many negative factors influence the eating habits of adults with mental retardation: poor role models at home, work, in the community, and on TV; environments that encourage unhealthy eating habits; limited skills in food preparation and self-advocacy; and little incentive to change unhealthy eating behaviors. We propose to develop a series of instructional modules to increase behavioral capability, self-efficacy, and outcome expectations for these individuals in the following areas: eating more fruits, juice, vegetables and low fat foods (FJV&LFF) at home (primarily snacks), increasing FJV&LFF availability and accessibility, increasing their nutritional knowledge about FJV&LFF, expanding their preferences for these foods, increasing their skills in preparing healthy snacks, and increasing their purchases of FJV&LFF in fast food restaurants and convenience stores. The primary goal of Phase I and Phase II is to conduct a randomized trial of a theory-based intervention to increase consumption of FJV&LFF among adults with mental retardation. The research settings will be residential facilities where these individuals live. The study will be conducted in two phases. In Phase I, we will modify and evaluate existing food assessment instruments, and develop and conduct a usability evaluation of the first module of the curriculum.
