A random-digit-dialing survey to examine the prevalence, content, and impact of physician dietary recommendations in a representative population-based sample of Washington State residents was administered to 1972 persons aged 18 years and older. Twenty percent of those surveyed received a physician's recommendation for dietary change in the previous year. The most common recommendations were to decrease intake of cholesterol, calories, and red meat and to increase intake of vegetables and fiber. Respondents receiving recommendations were more likely to report decreased use of high-fat foods and increased use of high-fiber foods and to be in the maintenance stage of dietary change. Results suggest that physicians can play a limited role in promoting dietary change.
一项针对华盛顿州居民具有代表性的基于人群样本的随机数字拨号调查，旨在研究医生饮食建议的普遍性、内容及影响，该调查面向1972名18岁及以上的人群展开。在接受调查的人群中，20%的人在过去一年收到了医生关于饮食改变的建议。最常见的建议是减少胆固醇、卡路里和红肉的摄入量，增加蔬菜和纤维的摄入量。收到建议的受访者更有可能报告减少了高脂肪食物的摄入，增加了高纤维食物的摄入，并且处于饮食改变的维持阶段。结果表明，医生在促进饮食改变方面作用有限。
