目的 探讨患者参与饮食管理对胃癌术后患者营养状况的影响.方法 将符合纳入标准的52例胃癌术后患者随机分为试验组和对照组,每组各26例.对照组接受一般饮食指导,试验组在接受一般饮食指导的同时,还接受患者参与式饮食管理.在干预前、干预后2周、干预后12周进行体重和BMI的测定,采用患者整体营养主观评估量表、饮食相关症状量表、饮食依从性量表及“3日饮食日记”进行调查.结果 干预后12周与干预前相比,试验组的体重、BMI无明显变化,对照组逐渐降低;两组的整体营养主观评估量表得分的时间效应差异具有统计学意义(P＜0.05);两组的饮食相关症状、饮食摄入量及饮食依从性的组间效应差异具有统计学意义(P＜0.05).结论 患者参与饮食管理能够改善胃癌术后患者的营养状况.%Objective To explore the effects of patient participation-based dietary intervention on nutritional status for patients with gastrectomy.Methods Fifty-two patients with gastrectomy were randomly assigned to the intervention group(n=26) and the control group(n=26).All patients were given general dietary guidance,and patients in the intervention group were provided patient participation-based dietary intervention(PPDI) as well.Height,body weight and body mass index(BMI) were recorded at baseline,2 weeks and 12 weeks after intervention,using PatientGenerated Subjective Global Assessment(PG-SGA),Diet-Related Symptom Scale,Adherence to Dietary Scale and a "3-day food diary".Results There was no obvious change in body weight and BMI before and after 12-week intervention,while outcomes in the control group gradually decreased.For time effect,there was significant difference in PG-SGA between two groups(P＜0.05).For between-group effect,there were significant differences in diet-related symptoms(P＜0.05),dietary intake(P＜0.05) and adherence to dietary(P＜0.05) between two groups.Conclusion Patient participation-based dietary intervention can improve nutritional status for patients with gastrectomy.
