Nutritional Status and Body Composition of Adult Patients With Crohn's Disease

Study Overview
=================
Brief Summary
-----------------
Patients with Crohn's disease generally have nutritional risks and malnutrition. The investigators will conduct a multicenter cross-sectional study to discover nutritional status and body composition of Chinese adult patients with CD.

Detailed Description
-----------------
Several studies have found that the body composition of CD patients is related to disease and therapies. Due to lack of a prospective multicenter cross-sectional observational study on the nutritional status and body composition of adult patients with CD in China. Evaluating the nutritional status and body composition of these patients can help formulate individualized nutritional support strategies for adult CD patients.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Appendicular skeletal mass index | Bioelectrical impedance analysis | Within 48 hours of admission to hospital | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Body composition | Especially body fat mass by bioelectrical impedance analysis | Within 48 hours of admission to hospital | 
| Nutritional risk screening | Detect the presence of undernutrition and the risk of developing undernutrition by Risk Screening 2002 (NRS-2002), when score≥3, the patient is nutritionally at-risk | Within 48 hours of admission to hospital | 
| Nutritional assessment | Detect malnourished individuals by the Subjective Global Assessment (SGA) , where A is well nourished and C is severely malnourished | Within 48 hours of admission to hospital | 
| Grip strength | Hand grip strength test | Within 48 hours of admission to hospital |
