目的:了解住院病人营养不良的患病率及其分布。方法:采用回顾性的调查方法,对北京和上海7所三甲综合医院的4 549例住院病人病例进行调查。结果:低体重患病率,入院时、住院中和出院时分别为11.12%、12.22%和14.62%;低清蛋白血症患病率,入院时、住院中和出院时分别为20.27%、31.57%和19.75%;营养不良性贫血患病率,入院时、住院中和出院时分别为40.36%、53.12%和50.66%。结论:住院病人营养不良发生率高,病人入院时已有较高的营养不良患病率,在疾病治疗过程中营养状况未获得改善,故出院时的营养指标均低于入院时。
Objectives: To understand the prevalence and distribution of malnutrition in hospitalized patients. Methods: A retrospective survey method was used to investigate the 4 549 inpatient cases in 7 KCRCs in Beijing and Shanghai. Results: The prevalence of low birth weight was 11.12%, 12.22% and 14.62% at admission, at hospitalization and at discharge, respectively. The prevalence of hypoproteinemia was 20.27%, 31.57 % And 19.75% respectively. The prevalence of malnutrition anemia was 40.36%, 53.12% and 50.66% at hospital admission, hospital stay and discharge respectively. Conclusion: The incidence of malnutrition in hospitalized patients is high. The patients have higher malnutrition prevalence at admission, and their nutritional status has not been improved during the treatment of the disease. Therefore, the nutritional indicators at discharge are lower than those at admission.
