背景：增加水果和蔬菜的摄入量可以降低癌症风险。这项研究的信息有助于探索高风险饮食行为的健康差异。目的：评估水果和蔬菜行为的变化，以评估低强度、医生认可的饮食干预对农村人口的影响。方法：该研究是对来自弗吉尼亚州农村地区 3 个医生诊所的 754 名患者进行的随机试验。通过邮件和电话提供低识字率营养教育材料和个性化饮食反馈。使用混合模型方差分析来确定干预措施对 1、6 和 12 个月时水果和蔬菜摄入行为、知识、意图和自我效能的影响。结果：干预效果受到年龄、种族、性别和教育程度的调节。对于年龄较大、年龄较小的参与者以及具有一定大学学历的参与者，在 1 个月和 6 个月时的摄入量有所增加，对于未完成高中学业的参与者，进一步维持在 12 个月时的摄入量。干预组中的非裔美国人比白人/其他人表现出明显更大的增加水果/蔬菜摄入量的意愿。 12 个月时，干预组对水果/蔬菜建议的了解显着增加，尤其是男性。结论：对于农村人口，医生认可的低强度自助饮食干预成功地在干预后 1 个月和 6 个月开始改变水果和蔬菜饮食，并增加了非裔美国人改变的意愿。农村人口膳食干预和膳食行为改变方面，年龄、种族、性别和教育程度的调节作用之间的关系需要进一步探讨。
Context: Increased fruit and vegetable intake can reduce cancer risk. Information from this study contributes to research exploring health disparities in high-risk dietary behavior. Purpose: Changes in fruit and vegetable behavior were evaluated to assess the effects of a low-intensity, physician-endorsed dietary intervention in a rural population. Methods: The study was a randomized trial of 754 patients from 3 physician practices in rural Virginia. Low-literacy nutrition education materials and personalized dietary feedback were administered by mail and telephone. Mixed model analysis of variance was used to determine the effect of the intervention on fruit and vegetable intake behavior, knowledge, intentions, and self-efficacy at 1, 6, and 12 months. Findings: The intervention effect was moderated by age, race, sex, and education. Intake at 1 and 6 months was increased for older and younger participants and those with some college, and further maintained at 12 months by those who did not complete high school. African Americans in the intervention group displayed significantly greater intentions to increase fruit/vegetable intake than whites/others. Knowledge of fruit/vegetable recommendations significantly increased in the intervention group at 12 months, particularly for men. Conclusions: For the rural population, a low-intensity physician-endorsed self-help dietary intervention was successful in initiating fruit and vegetable dietary changes at 1 and 6 months post-intervention, and increasing intentions to change in African Americans. The relationship of the moderating effects of age, race, sex and education need to be further explored in relation to dietary intervention and dietary behavior change for the rural population.
