To explore the correlation of malnutrition inflammation(MHD) complex syndrome with nutritional risk and life quality in patients with maintenance hemodialysis.

Sixty-one patients with MHD≥3 months in the first affiliated hospital of Kunming medical university and Yunnan kidney disease hospital were enrolled into this respective study, the NRS2002 was used to screen nutritional risk, the short form 36 health survey questionnaire (SF-36) scale was used to investigate the quality of life, the malnutrition inflammation score (MIS score) was used to test MHD patients' MICS, the patients with MICS were divided into mild (MIS≤4), moderate (5≤MIS≤8) and severe group (MIS≥9).

①The comparison of MIS between the two groups in which patients with or without nutrition risk had statistically significant difference (P<0.01), The MIS and NRS2002 had a positive correlation (r = 0. 612, P<0.01). ② The grip among the different MICS groups was statistically significant difference (P<0.05). ③The comparison of limited working and living score caused by strength among the different MICS groups had statistically significant difference (P<0.05), and there were statistically significant differences in the MIS score and SF-36 scores, physiological and psychological fields, physical fitness, limited working and living score caused by strength, social function had a negative correlation (P<0.05). ④The comparison of life quality between the two groups in which patients with or without nutrition risk had no difference (P>0.05).

For MHD patients, the higher the nutrition risk is, the more serious malnutrition inflammation complex syndrome will be, the more serious malnutrition inflammation complex syndrome is, the worse life quality will be.
