目的了解不同供餐模式下特勤疗养员膳食营养摄入情况,为探索适合疗养院推广的供餐模式提供参考。方法以南京军区杭州疗养院直属院区(配餐模式)及海勤疗区(自助餐模式)的特勤人员为对象,采用称重法进行为期3d的膳食调查,同时采用军人食物定量、军人营养素供给量标准评价膳食营养中存在的问题。结果与自助餐模式相比,除粮食、蔗糖外,配餐模式下所有食物的剩余率均明显减少(P<0.05);自助餐模式下脂肪供能比例偏高、碳水化合物供能比例偏低,配餐模式下三大产能营养素供能比例基本符合军标要求,二者相比差异有显著性(P<0.05);自助餐模式下,植物油和胆固醇的摄入明显超标,分别为192.6%和178.3%,配餐模式下,二者的达标率分别为90.3%和99.8%,减少明显(P<0.05);自助餐模式下,维生素A、维生素B_1、维生素B_2和钙摄入不足,配餐模式下,维生素A和维生素B_2摄入不足,但与自助餐模式相比,维生素A、维生素B_1、维生素B_2和钙的摄入量增加明显(P<0.05)。结论与配餐模式相比,自助餐模式更易出现营养不合理,浪费更多,因此,应对自助餐进行科学有效的营养膳食管理,并探索适合疗养院推广的合理有效的供餐模式和管理方法。
Objective To understand dietary intake of dietitians in different feeding modes and to provide reference for exploring feeding modes suitable for nursing home promotion. Methods A special dietary survey was carried out using the weighing method for the 3d special dietary workers in the hospital affiliated to Hangzhou Sanatorium in Nanjing Military Region (catering mode) and in the Haidian Area (buffet mode). At the same time, the food quality of military personnel, Evaluation of dietary problems in the nutrition. Results Compared with the buffet model, the remaining rate of all the food except catering food and cane sugar was significantly reduced (P <0.05); the fat feeding ratio was high in the buffet mode, the carbohydrate energy supply ratio was low, and the catering mode The ratio of nutrient supply to energy under the three major production lines basically met the requirements of the military standard. The difference between the two was significant (P <0.05). In buffet mode, the intake of vegetable oil and cholesterol exceeded the standard levels by 192.6% and 178.3% respectively. Mode, the compliance rate of the two was 90.3% and 99.8%, respectively, significantly decreased (P <0.05); under the buffet mode, vitamin A, vitamin B_1, vitamin B_2 and calcium intake were inadequate. In the catering mode, vitamin A and vitamin B_2, but intake of vitamin A, vitamin B_1, vitamin B_2 and calcium increased significantly (P <0.05) compared with the buffet mode. Conclusion Compared with the catering model, the buffet model is more prone to irrational nutrition and more waste. Therefore, it is necessary to carry out scientific and effective nutrition and dietary management of the buffet and to explore reasonable and effective feeding modes and management methods suitable for the promotion of nursing homes.
