Abstract:
BACKGROUND: The hot environmental condition of the isolated severe acute respiratory syndrome (SARS) ward makes the protein transformation of the medical personnel accelerated. The dietary protein should make up the special consumption and improve the immunity in addition to guaranteeing the normal metabolism for the purpose to promote the organic endurance and resist the communicable disease.OBJECTIVE: To study the scientific mode of quality and quantity of protein supply for the medical staff working in the SARS ward.DESIGN: A cross section analysis.SETTING: Trophological Department, General Hospital of Chinese People's Armed Police Forces.PARTICIPANTS: The 64 healthy doctors and nurses, 22 males and 42females, aged 29 averagely, worked in the SARS ward from May 1st to 20th 2003, were the volunteers to join the observation.METHODS: The weighing method was applied to measure the quantity of various food supplied by recipe and actually taken and the nutrition software was used to analyze the quantity of protein and amino acid contained in the food. The quantity of protein supply (taking male as standard) calculated according to the heavy consumption, 1.5 g/kg.d, in the hot environment was compared with the estimated consumption, male (108.00±12.63) g and female (85.21±9.55) g, and with the actual intake analyzed by computer. The corrected scoring of digestibility was employed to evaluate the reasonability of intake of various essential amino acids. The quantity of essential amino acids contained in every gram of protein of recipe/the amino acids contained in Reference Mode of Chinese Food × 93% being higher than 1.0 was said to be the quality protein meeting the need of human body.MAIN OUTCOME MEASURES:① The quantity and composition of protein supplied by the recipe. ② The quantity and composition of protein actually taken by the working staff.RESULTS: All of the 64 medical working staff entered the result analysis.① The protein supply of recipe (daily average) could totally meet the need of estimated consumption of male and female staff [(157.36±10.43) g,(108.00±12.63) g, (85.21±9.55) g, t=9.344, 18.278, P ＜ 0.01] and the need of actual intake [(157.70±58.14) g, (111.02±31.77) g, t= -0.015, 3.795, P＞ 0.05, P ＜ 0.01]. ② The corrected scores of 9 amino acids of digestibility, (1.9-3.1), were all higher than 1.0 and the percentage of amino acids was in accordance with the food mode of Chinese people.CONCLUSION: The protein quantity and quality of recipe can meet the special need of medical staff working in the hot environment with the heavy physical consumption in the SARS ward and can produce the best biological effect, being scientific.
