Abstract:

Objective   To analyze nutritional status and risk factors which lead to malnutrition in maintenance hemodialysis sufferers, and provide the basis for nutritional intervention. Methods   98 sufferers underwent a 3-day retrospective 24-hour dietary survey, nutritional status assessment with Modified Quantitative Subjective Global Assessment(MQSGA),  and necessary somatological and biochemical measurements. Results   The diet survey showed that actual standard body mass daily energy intake(DEI) was (117.15±5.98)kJ/(kg·d), actual standard body mass daily protein intake(DPI) was (1.02±0.42)g/kg·d, and superior quality protein intake quantity was (19.8±12.9)g/d. Sufferers′ DEI, DPI and superior quality protein intake were all lower than the recommended standard. Nutritional status assessment showed that the malnutrition incidence was 48.9%. Sufferers with sufficient dialysis demonstrated a lower malnutrition incidence than those with insufficient dialysis. There was significant difference between the two groups(P<0.05). The malnutrition incidence in sufferers at or above 60 years old was obviously higher than those under 60 years old(P<0.05). Conclusion   The malnutrition incidence in maintenance hemodialysis sufferers is high, which is primarily related to the age and insufficiency in dialysis and protein and energy intake.
