BACKGROUND
To assess the nutrition knowledge of physicians on the basic effects of diet on blood lipids and lipoproteins.
METHODS
Anonymous mailed dietary knowledge surveys to 6000 randomly selected physicians in the United States licensed in either Internal Medicine or Cardiology.
RESULTS
Response rate: 16% (n = 639). Half of the physicians did not know that canola oil and 26% did not know olive oil were good sources of monounsaturated fat. Ninety-three percent (84% of cardiologists vs. 96% of internists; p < 0.001) did not know that a low-fat diet, in general, would increase blood triglycerides. Approximately three-quarters (70% of cardiologists vs. 77% of internists; p < 0.01) did not know a low-fat diet would decrease HDL-c and almost half (45%) thought that a low-fat diet would not change HDL-c.
CONCLUSIONS
If physicians are to implement dietary and cholesterol management guidelines, they will likely need to become more knowledgeable about nutrition.
背景
评估医生关于饮食对血脂和脂蛋白的基本影响的营养知识。
方法
向美国6000名随机抽取的、在内科或心脏病学领域获得执照的医生邮寄匿名饮食知识调查问卷。
结果
回复率：16%（n = 639）。一半的医生不知道菜籽油是单不饱和脂肪的良好来源，26%的医生不知道橄榄油是单不饱和脂肪的良好来源。93%（心脏病专家为84%，内科医生为96%；p < 0.001）的医生不知道一般情况下低脂饮食会增加血液甘油三酯。大约四分之三（心脏病专家为70%，内科医生为77%；p < 0.01）的医生不知道低脂饮食会降低高密度脂蛋白胆固醇，近一半（45%）的医生认为低脂饮食不会改变高密度脂蛋白胆固醇。
结论
如果医生要实施饮食和胆固醇管理指南，他们可能需要对营养有更多的了解。
