目的 探讨基于计划行为理论的饮食管理对改善腹膜透析患者蛋白质能量消耗的效果。方法 采用便利抽样法，选取郑州大学第一附属医院腹膜透析中心2020年7月-2021年12月终末期肾病行腹膜透析且诊断为蛋白质能量消耗的76例患者为研究对象，随机分为两组，对照组和试验组各38例。对照组患者给予肾脏内科常规饮食管理，试验组患者在此基础上，给予基于计划行为理论的饮食管理，比较干预前、干预6个月和随访3个月两组患者主观综合性营养评估(subjective global assessment，SGA)、人体测量指标、生化指标及蛋白质和热量摄入变化。结果 干预前两组患者一般资料差异无统计学意义(P＞0。05)，干预6个月后及随访阶段试验组患者营养状况、营养指标、人体测量学指标均高于对照组，两组差异均具有统计学意义(P＜0。05);3 d饮食日记结果中蛋白质、饮食热量的摄入量与对照组相比，差异均具有统计学意义(P＜0。05)。结论 基于计划行为理论的饮食管理可以促进腹膜透析患者形成良好的饮食行为，改善腹膜透析患者蛋白质能量消耗状况。
Effects of diet management based on theory of planned behavior on improvement of protein energy consumption in peritoneal dialysis patients
Objective To explore the effect of dietary management based on the theory of planned behavior on improving protein and energy expenditure in peritoneal dialysis patients.Methods Using convenience sampling method,76 pa-tients with end-stage renal disease who were diagnosed as protein-energy consumption and underwent peritoneal dialy-sis from January 2019 to December 2019 in the Department of Nephrology of the First Affiliated Hospital of Zhengzhou U-niversity were randomly divided into two groups,the control group and the experimental group each 38 cases.The con-trol group was given routine diet management,the experimental group was given diet management based on planned be-havior theory.the changes of subjective global assessment(SGA),anthropometric parameters,biochemical parameters,protein and caloric intake were compared before intervention,6 months after intervention and 3 months after follow-up.Results There was no significant difference in general data between the two groups before intervention.After 6 months of intervention and at the follow-up stage,the nutritional status,nutritional index and anthropometry index of the exper-imental group were higher than those of the control group,the difference between the two groups was statistically signifi-cant(P＜0.05),and the intake of protein and dietary energy in 3-day diet diary was statistically significant(P＜0.05).Conclusion Dietary management based on the theory of planned behavior can promote the formation of good dietary behavior and improve the status of protein and energy consumption in peritoneal dialysis patients.
