摘要目的：探讨行为分阶段转变理论在血液透析患者中的应用。方法选择138例血液透析患者为研究对象，分3个阶段进行干预，比较干预前后患者临床生化指标的变化情况。结果实施干预后，患者血清白蛋白及血红蛋白分别为（39．3±9．1），（108．8±11．7） g/L，明显高于实施前的（37．2±8．3），（105．6±10．4）g/L，干预前后比较差异有统计学意义（t值分别为-2．0029，-2．4014；P＜0．05）。干预前患者收缩压为（148．6±20．5）mm Hg，K＋和Na＋浓度分别为（5．5±1．4），（146．1±16．5）mmol/L，干预后患者收缩压为（141．2±22．3）mmHg，K＋和Na＋浓度分别为（4．9±1．3），（139．2±20．3）mmol/L，均较干预前明显降低，干预前后比较，差异有统计学意义（ t值分别为2．8699，3．6893，3．0985；P＜0．05）。干预后患者体质量、血压和无明显水肿达标率明显提高（P＜0．05）。干预后，SGA评估营养良好的患者较干预前明显增加，分别为40例（44．9％），70例（78．7％），干预前后比较差异有统计学意义（χ2＝16．49，P＜0．05）。结论行为分阶段转变理论有利于控制血液透析患者的血压，改善预后，提高患者生活质量。

abstractsObjective To explore the application of the transtheoretical model and stages of change in maintenance hemodialysis patients .Methods One hundred and thirty-eight maintenance hemodialysis patients were chosen and received the three stages of interventions according to the transtheoretical model and stages of change.The changes of clinical biochemical indicator were compared before and after the intervention . Results The levels of the serum albumin and hemoglobin were respectively (39.3 ±9.1) g/L, (108.8 ± 11.7)g/L after the intervention, and were significantly higher than (37.2 ±8.3) g/L, (105.6 ±10.4) g/L&nbsp;before the intervention, and the differences were statistically significant (t=-2.002 9, -2.401 4, respectively;P<0.05).The systolic blood pressure, the concentrations of K +and Na +were respectively (148.6 ±20.5) mmHg, (5.5 ±1.4)mmol/L, (146.1 ±16.5)mmol/L before the intervention, and were significantly higher than (141.2 ±22.3)mmHg, (4.9 ±1.3)mmol/L, (139.2 ±20.3)mmol/L after the intervention, and the differences were statistically significant (t=2.869 9, 3.689 3, 3.098 5, respectively; P<0.05).The body weight, blood pressure and the compliance rate of no obvious edema were significantly increased after the intervention (P<0.05).The cases of well nourished patients evaluated by the SGA were 40 cases (44.9%) before the intervention, and were 70 cases (78.7%) after the intervention, and the difference was statistically significant (χ2 =16.49, P<0.05).Conclusions Transtheoretical model and stages of change is beneficial to control blood pressure , improve the prognosis , and increase the life quality of maintenance hemodialysis patients .
