We assessed nutrition status and prevalence of malnutrition in hospital patients as determined by the Subjective Global Assessment Form, awareness of patients' nutrition status by health teams, and the use of nutrition therapy.
We enrolled 4000 hospital patients at least 18 y old who were covered by the Brazilian public health care system in a cross-sectional, multicenter epidemiologic study. We used Student's t and chi-square tests for univariate and multiple logistic regression analyses.
Malnutrition was present in 48.1% of patients and severe malnutrition was present in 12.5% of patients. The prevalence of malnutrition was higher in the northern and northeastern regions of Brazil, where per-capita income is lower. Malnutrition correlated with primary diagnosis at admission, age (60 y), presence of cancer or infection, and longer hospital stay (P < 0.05). Fewer than 18.8% of patients' records contained information on nutrition-related issues. Nutrition therapy was used in 7.3% of patients (6.1% enteral nutrition and 1.2% parenteral nutrition).
The prevalence of malnutrition in hospitalized patients in Brazil is high, physician awareness of malnutrition is low, and nutrition therapy is underprescribed.
我们通过主观全面评定量表评估住院患者的营养状况及营养不良患病率、医疗团队对患者营养状况的认知情况以及营养治疗的使用情况。
在一项横断面多中心流行病学研究中，我们纳入了4000名年龄至少18岁、参加巴西公共卫生保健系统的住院患者。我们使用学生t检验和卡方检验进行单变量和多变量逻辑回归分析。
48.1%的患者存在营养不良，12.5%的患者存在严重营养不良。在巴西人均收入较低的北部和东北部地区，营养不良的患病率更高。营养不良与入院时的初步诊断、年龄（60岁）、癌症或感染的存在以及住院时间延长相关（P<0.05）。患者记录中关于营养相关问题的信息不到18.8%。7.3%的患者接受了营养治疗（6.1%为肠内营养，1.2%为肠外营养）。
巴西住院患者中营养不良的患病率很高，医生对营养不良的认知度较低，营养治疗的处方不足。
