目的  了解CNT 培训对提高护理人员营养K-A-P 水平的效果。方法 对肿瘤专业护理人员进行CNT 培训， 培训前后进行营养K-A-P 调查，对所得结果进行统计学分析，培训前后比较采用配对t 检验，分组比较时采用两独立样 本 t 检验，多组间比较采用单因素方差F 检验。结果  经肿瘤营养疗法培训后，总体肿瘤护理人员的营养K-A-P 总分高于 培训前（145.53±24.10 vs. 207.02±24.95，t 值 -12.793，P ＜ 0.001）；营养知识得分（K 分）高于培训前（16.38±9.19 vs. 61.06±12.38， t值-20.806， P＜0.001）；营养态度得分（A分）高于培训前（77.34±11.56 vs. 86.17±9.62， t值-4.290， P＜0.001）； 营养行为得分（P 分）高于培训前（51.81±14.16 vs. 59.79±17.41，t 值 2.317，P ＜ 0.05）；分不同工作年限比较，培训前后 各组间K-A-P 总分差值、K 分差值、P 分差值有区别，工作年限5~10 年的肿瘤护理人员改善程度最好，其次是工作年限 15年以上的肿瘤护理人员，工作年限10~15年的肿瘤护理人员改善程度最差（F=9.407，P＜0.001； F=7.455，P＜0.05； F=3.664，P＜0.05），而 A分差值在各组间无差别（P＞0.05）；分不同级别医院比较，培训前后各组间K-A-P总分差值、 K 分差值有区别（t=-4.555，P ＜ 0.001；t=-3.780，P ＜ 0.001），非三甲医院的肿瘤护理人员改善程度好于三甲医院的肿瘤 护理人员；A分差值、P分差值各组间无差别（P＞0.05）。结论  肿瘤营养疗法培训能有效提高护理人员的营养知识-态度行为水平，值得进一步推广应用。

Objective To investigate the effect of CNT training on the nutritional K-A-P level of nursing staff. Methods Training the nursing staffs with knowledge of CNT and investigate the nutritional K-A-P level. Paired t test was used to test the differences before and after training. Two independent samples t test was used to compare the differences between groups. The single factor variance F test was used to compare the differences among multiple groups. Results After the training, the total score of K-A-P level, the knowledge score (K), the attitude score (A), the practice score (P) were all higher than the sores before training (K-A-P total score: 145.53 ± 24.10 vs. 207.02 ± 24.95, t = -12.793, P<0.001; K score: 16.38 ± 9.19 vs. 61.06 ± 12.38, t=-20.806, P<0.001; A score: 77.34 ± 11.56 vs. 86.17 ± 9.62, t = -4.290, P<0.001; P score: 51.81 ± 14.16 vs. 59.79 ± 17.41, t=2.317, P<0.05). Compared the difference of K-A-P level before and after training among subgroups in different working years, there were significant differences in the total score of K-A-P level, K score and P score. The nursing staffs who worked from 5 to 10 years had the best response. The nursing staffs who worked more than 15 years had the second response. The staffs who worked 10 to 15 years had the worst response (F=9.407, P<0.001; F=7.455, P<0.05; F=3.664, P<0.05). But there was no difference of A score among working year groups (P>0.05). Compared the difference of K-A-P level before and after training among different level of hospital, there were significant difference in the total score of K-A-P level and K score (t=-4.555, P<0.001; Difference of K score: t=-3.780, P<0.001). The improvement for nursing staffs from Non-3A hospital was better than the staffs from 3A hospital. There were no differences in A score and P score (P>0.05). Conclusions The CNT training could effectively improve the level of nutritional knowledge, attitude and practice for nurses. It was worth to be popularized and applied to more nursing staffs.
