MOTIVATING DIETARY CHANGES IN CHURCHES

我们知道如何改变积极进取的人的饮食习惯。这个 我们过去的随机干预试验结果表明，如果人们 准备好并有动力改变饮食行为，有可能 成功是非常高的。我们对如何改变饮食结构知之甚少 还没有动力去尝试改变的个人的习惯。我们 假设我们自己和别人的研究中的两个发现将 增加改变饮食的动力：社会支持的关系 到健康行为，以及专门设计的信息的效果 激励个人做出改变。这项提案将严格考验一项 干预方案，基于我们以前的经验，旨在改变 饮食习惯(降低脂肪，增加水果和蔬菜 消费)在较低的社会经济(SES)家庭中 组织。我们选择宗教组织是因为 他们在成员的生活中扮演着重要的角色，因为 他们可以传递的社交和支持性信息。这个 一揽子干预措施将传递社会支持和激励信息， 以及改变饮食的材料和技能培养机会。 40个宗教组织将随机接受干预或 比较状态。为期18个月的干预方案，基于合并 社会学习理论与行为改变的跨理论模型， 将由改编自已证实有效的干预措施的材料组成 提出了改变当前行为的策略，传递了 影响动机和信念以及组织范围的干预 会影响环境变量。我们的评估将基于 从每个宗教组织的邮寄名单中随机挑选的队列。 饮食习惯将在基线和6个月和18个月的随访中进行评估， 使用脂肪和纤维行为问卷的修改版本，以及 被选为24小时召回的子集。干预过程 将被测量并用作所有人饮食变化的中介 干预组织。主要结果将是 干预和对照宗教之间肥胖分数的变化 组织。

We know how to change the dietary habits of motivated individuals. The results of our past randomized intervention trials indicate that if people are ready and motivated to change dietary behaviors, the likelihood of success is very high. We know far less about how to change the dietary habits of individuals who are not yet motivated to attempt changes. We hypothesize that two finding from our own and others' research will increase motivation for dietary change: the relationship of social support to health behaviors, and the effects of messages specifically designed to motivate individuals to change. This proposal will rigorously test an intervention package, based on our previous experience, designed to change dietary practices (lowering fat, increasing fruit and vegetable consumption) among lower socioeconomic (SES) families in religious organizations. We selected religious organizations because of the important role they play in the lives of their members and because of the social and supportive messages that can be delivered by them. The intervention package will deliver social support and motivating messages, as well as materials and skill-building opportunities for dietary change. Forty religious organizations will be randomized to intervention or comparison status. The 18-month intervention package, based on a merger of Social Learning Theory and Trans-theoretical Model of Behavior Change, will consist of material adapted from interventions of proven efficacy that present strategies for changing current behavior, messages that influence motivations and beliefs, and organization-wide interventions that affect environmental variables. We will base evaluation upon a randomly selected cohort from each religious organization's mailing list. Dietary habits will be assessed at baseline and 6 and 18 months follow-up, using a modified version of the Fat and Fiber Behavior Questionnaire, with a subset selected to receive 24-hour recalls. The intervention process will be measured and used as a mediator of dietary change in all intervention organizations. The primary outcome will be the difference in change in fat scores between intervention and comparison religious organizations.
