靶强度有氧运动锻炼对腹膜透析患者营养状态的影响

目的 探讨基于无氧阈评估的靶强度有氧运动锻炼对腹膜透析患者营养状态的改善效果。 方法 将147例腹膜透析患者随机分为对照组(73例)和观察组(74例),对照组实施常规护理,观察组在常规护理的基础上实施靶强度有氧运动锻炼,收集并比较2组患者在干预前及干预3、6个月后微营养评估(micronutrition assessment, MNA)、腹膜透析后中臂肌围(middle arm muscle circumference, MAMC)和静脉血检验指标的变化。 结果 2组MNA得分、MAMC、血清清蛋白、前清蛋白、血磷和血肌酐的组间效应、时间效应以及交互效应差异均具有统计学意义。 结论 基于无氧阈评估的靶强度有氧运动锻炼可以有效改善腹膜透析患者的营养状态,提高生活质量和促进疾病的康复。

Study on the influence of target strength aerobic exercise on the nutritional status of peritoneal dialysis patients

Objective To explore the improvement effect of target strength aerobic exercise based on anaerobic threshold assessment on the nutritional status of peritoneal dialysis patients. Methods Totally 147 peritoneal dialysis patients were randomly divided into a control group (n=73) and an observation group (n=74). Both groups were given routine nursing, while the observation group was additionally provided with target strength aerobic exercise. Before and after 3-and 6-month intervention, both groups were evaluated using the micronutrition assessment (MNA) and middle arm muscle circumference (MAMC) after peritoneal dialysis and changes of related venous test indexes. Results The average scores of MNA, MAMC and serum albumin, prealbumin, phosphorus and serum creatinine of the observation group after the intervention were significantly higher than those before the intervention, and those of the control group at the same time points. Conclusion The target strength aerobic exercise based on anaerobic threshold assessment can effectively improve the nutritional status of peritoneal dialysis patients, as well as promote their life quality and rehabilitation.
