应用营养风险筛查2002（NRS2002）对朝阳医院西区外科住院系统腹壁感染合并2型糖尿病患者进行营养风险分析，评价腹壁感染合并2型糖尿病住院患者营养状况，明确营养风险在年龄上有无差异。

应用NRS2002对朝阳医院西区135例外科术后腹壁感染合并2型糖尿病住院患者采用连续定点抽样方式收集患者一般信息，在入院2 d内进行营养风险筛查，分析患者住院期间的营养状况，评估营养支持其必要性。其中男性83例，女性52例，年龄41～82（65.0±9.2）岁。NRS2002评分为营养状况评分、疾病严重程度评分、年龄评分（<70岁为0分，≥70岁年龄评分为1分）3项的总和。

135例住院患者全部完成营养风险筛查NRS2002，其中有营养风险（NRS-2002评分≥3分）49例（36.8%），无营养风险（NRS-2002评分<3分）86例（63.8%）。存在营养风险和无营养风险患者的营养干预治疗率分别为65%和19%。营养风险在年龄上随着年龄增长在70岁以后有差异，年龄≥70岁的患者其营养风险的发生率高于年龄<70岁的患者。

在腹壁感染合并2型糖尿病住院患者中，存在较高营养不良和营养风险发生率，NRS-2002量表简单、易行，可有效筛查腹壁感染合并2型糖尿病住院患者的营养状况。

To apply nutritional risk screening 2002 (NRS2002) to analyze the nutritional risk of abdominal wall infection patients with type 2 diabetes mellitus in the western campus of Beijing Chaoyang hospital and to evaluate the nutritional status of hospitalized patients with abdominal wall infection combined with type 2 diabetes, and to know whether there is any difference in nutritional risk in age.

A total of 135 patients with abdominal wall infection and type 2 diabetes mellitus in the western campus of Beijing Chaoyang hospital were collected by NRS2002. The general information was collected by continuous fixed-point sampling. Nutritional risk screening was carried out within 2 days after admission, the nutritional status of patients during hospitalization was analyzed, and the necessity of nutritional support was evaluated. There were 83 males and 52 females, aged from 41 to 82 (65.0±9.2) years. NRS2002 score is the sum of nutritional status score, disease severity score and age score (<70 years old is 0 and ≥70 years old is 1).

All 135 inpatients completed nutritional risk screening NRS2002, including 49 cases (36.8%) with nutritional risk (NRS2002 score ≥3 points) and 86 cases (63.8%) without nutritional risk (NRS2002 score <3 points). The nutritional intervention rates of patients with nutritional risk and patients without nutritional risk were 65% and 19%, respectively. The nutritional risk varies with age after 70 years old. The incidence of nutritional risk in patients aged ≥70 years old was higher than that in patients aged <70 years old.

There is a high incidence of malnutrition and nutritional risk in hospitalized patients with abdominal wall infection and type 2 diabetes. The NRS2002 scale is simple and easy to perform. It can effectively screen the nutritional status of abdominal wall infection patients with type 2 diabetes.
