Application of motivational interviewing on nutrition management among patients with stage III-IV chronic kidney disease

Abstract

Objective To explore the effect of motivational interviewing on nutrition management among patients with stage Ⅲ-Ⅳ chronic kidney disease. Methods A total of 64 patients with stage Ⅲ-Ⅳ chronic kidney disease were averagely divided into experimental group (routine health education) and control group (health education of motivational interviewing) by random sequence number for 6 months intervention. We utilized general evaluation scale, SGA improvement scale of kidney patients, behavior change and self-efficacy scale to investigate and compared the change of nutrition status and related indexes before and after intervention. Results After intervention, the nutrition status and nutrition ingredient intake status of experimental group was better than these of the control group (P>0.05). Hemoglobin, albumin, total cholesterol, glycerin trilaurate, and serium inorganic phosphorus decreased in the experimental group after intervention (t=3.864 2, 5.648 1, 11.573 0, 2.285 3, 9.168 4, 6.654 1, 8.865 9, 8.265 7, respectively; P 0.05). The change of glomerulus filtration rate (GFR) in the experimental group had no statistical difference (t=0.195 4, P>0.05). Serum creatinine, usea nitrogen of control group increased, but GFR decreased after intervention (P<0.05). After intervention, behavior change and self-efficacy in both two groups improved and this of experimental group were higher than them in the control group (P<0.05). Conclusions The motivational interviewing can enhance patient′s behavior change, self-efficacy, and the compliance of patients′ diet change, and delay the process of kidney disease.
