Nutritional intake analysis of hospital diets in elderly inpatients in Peking Union Medical College Hospi-tal / 中华临床营养杂志

ABSTRACT

Objective To investigate the nutritional management level of Department of Clinical Nutrition in elderly inpatients through analyzing the actual hospital dietary intakes in elderly inpatients in Peking Union Medical College Hospital from 2013-2015.Methods Using continuous sampling, the nutrients contents and the eating rates of hospital meals ordered by the elderly inpatients on the 1st, 15th, 29th of every month from May 2013 to October 2015 were selected.The intake levels of energy, protein, calcium, vitamin A, vitamin B1 , and vitamin C were calculated and compared with the Chinese dietary reference intakes (DRIs).The nutritional in-take differences between diabetes diet and the basic hospital diet were also compared.Results A total of 90 days of hospital dietary data from 8 402 elderly inpatients were included in the study.The average eating rate was (50.1 ±4.2)%, which was lower than the general eating rate of the hospital [ (59.0 ±4.0)%, P<0.001]. Only protein intake from hospital diet reached the requirement target [male (103.1 ±47.3)%, femal (98.3 ± 33.8)%].Individual compliance rates were 63.2%and 59.8%, respectively, while the other kinds of nutrients were lower.The compliance rates of energy [ (73.3 ±26.3)%vs.(62.1 ±38.2)%, P<0.001] and ma-jor nutrient intake [ protein ( 119.1 ±41.2 )% vs.( 93.3 ±65.1 )%, P <0.001; calcium ( 55.5 ± 26.7)% vs.(34.3 ±34.2)%, P <0.001; vitamin A (75.2 ±48.3)% vs.(57.4 ±97.1)%, P<0.001;vitamin B1(76.4 ±38.2)%vs.(52.1 ±46.6)%, P<0.001;vitamin C(92.2 ±51.4)%vs. (49.3 ±55.0)%, P<0.001) in diabetes diet group were significantly higher than those in the basic hospi-tal diet group.Conclusions The nutritional intakes from hospital diets may not meet the nutritional require-ments based on DRIs in elderly inpatients.Medical diet designed by physicians and dietitians should be ex-panded to improve the nutritional management level for these patients.
