Many people are afflicted with chronic diseases, in which nutrition plays a key role. The need for greater nutrition training among physicians, particularly gastroenterologists, is becoming increasingly evident.
To determine the nutritional knowledge and perceived nutrition knowledge of gastroenterology fellows.
Thirty-two gastrointestinal (GI) fellows currently enrolled in a GI fellowship program completed a needs assessment evaluating perceived nutrition knowledge and interest in the areas of nutrition support, assessment, obesity, micro/macronutrients, and nutrition in GI diseases. Additionally, an examination evaluating nutrition knowledge specific to gastroenterology fellows was administered.
Thirty-two GI fellows completed the needs assessment. Cronbach alpha of the needs assessment instrument was 0.72, indicating satisfactory internal consistency reliability. GI fellows perceived themselves to have the least knowledge in obesity and micro/macronutrients. They indicated a perceived greater knowledge base in nutrition assessment. The mean total test score was 50.04% (SD=7.84%). Fellows had the highest score in the subscale of nutrition assessment (80.64%; SD=19.05%), which was significantly higher than scores obtained in nutrition support (49.45%; SD=11.98%; P<0.05), micro/macronutrients (37.84%; SD=16.94%; P<0.05), obesity (40.11%; SD=20.00%; P<0.05), and nutrition in GI diseases (65.05%; SD=22.09%; P<0.05). A backward linear regression including hours of nutrition education received during GI fellowship, hours of nutrition education received during medical school, and year of GI fellowship accounted for 22.7% of the variance in test performance (multiple R=0.477).
Gastroenterology fellows think their knowledge of nutrition is suboptimal; objective evaluation of nutrition knowledge in this cohort confirmed this belief. A formal component of nutrition education could be developed in the context of GI fellowship education and continuing medical education as necessary.
许多人患有慢性病，营养在其中起着关键作用。医生，尤其是胃肠病学家，对更多营养培训的需求日益明显。
确定胃肠病学进修医生的营养知识以及他们对自身营养知识的认知。
32名目前参加胃肠病学进修项目的胃肠病（GI）进修医生完成了一项需求评估，该评估对他们对营养支持、评估、肥胖、微量/宏量营养素以及胃肠疾病营养等领域的营养知识认知和兴趣进行了评估。此外，还进行了一项针对胃肠病学进修医生特定营养知识的考试。
32名胃肠病进修医生完成了需求评估。需求评估工具的Cronbach α系数为0.72，表明内部一致性信度令人满意。胃肠病进修医生认为自己在肥胖和微量/宏量营养素方面的知识最少。他们表示在营养评估方面的知识储备更多。考试总平均分是50.04%（标准差=7.84%）。进修医生在营养评估子量表中的得分最高（80.64%；标准差=19.05%），显著高于在营养支持（49.45%；标准差=11.98%；P<0.05）、微量/宏量营养素（37.84%；标准差=16.94%；P<0.05）、肥胖（40.11%；标准差=20.00%；P<0.05）以及胃肠疾病营养（65.05%；标准差=22.09%；P<0.05）方面的得分。一项向后线性回归分析显示，胃肠病进修期间接受的营养教育时长、医学院学习期间接受的营养教育时长以及胃肠病进修年份，解释了考试成绩方差的22.7%（复相关系数=0.477）。
胃肠病学进修医生认为他们的营养知识欠佳；对该群体营养知识的客观评估证实了这一观点。可在胃肠病进修教育及必要的继续医学教育背景下，制定正式的营养教育内容。
