Nutritional Risk Factors for 499 Schizophrenia Inpatients in China

499 patients with schizophrenia hospitalized in Shanghai during 2019 were assessed for malnutrition risk using the NRS2002 tool. The study found a 22.44% prevalence of nutritional risk, with age and BMI identified as key independent factors. Data includes clinical characteristics and laboratory parameters compared between nutritional-risk and non-risk groups.

Use Cases

• Train a logistic regression model to predict NRS2002 nutritional risk category using age, BMI, and laboratory parameters like hemoglobin and albumin.
• Analyze correlations between length of hospital stay and NRS2002 scores to understand hospitalization impact on nutritional status.
• Build a risk scoring system using BMI as a discriminative feature, as indicated by ROC curve analysis in the study.
• Compare levels of total protein and albumin between nutritional-risk and non-risk groups to identify biochemical markers of malnutrition.

Strengths

• Focuses on a specific, understudied population of 499 long-term inpatients with schizophrenia in China.
• Uses a standardized nutritional assessment tool (NRS2002) for consistent risk categorization.
• Includes multivariate analysis identifying age and BMI as independent factors associated with nutritional risk.

Limitations

• Dataset scope is limited to a single center (Shanghai Third Mental Health Center), reducing generalizability.
• Data is presented in a summarized PDF report (73.2 KB), not as raw, analyzable tabular data.
• Sample is cross-sectional from a specific 7-month period in 2019, lacking longitudinal follow-up.
