Abstract
AbstractBackgroundIt is reported that reduced physical activity and malnutrition may trigger pneumonia, and the utilisation of the geriatric nutritional risk index (GNRI) upon admission to long‐term nursing care can enable the implementation of accurate and timely rehabilitation and nutritional support, which may, in turn, minimise pneumonia incidence. However, to date, there is no reported association between GNRI and pneumonia among stable schizophrenic patients.MethodsThis is a retrospective investigation. We enrolled 434 hospitalised subjects aged ≥50 years, who were diagnosed with stable schizophrenia between January 2017 and June 2022. Baseline nutritional status information during the stable stage of schizophrenia was evaluated using body mass index, serum albumin, and GNRI. In addition, pneumonia‐based information, including diagnosis and treatment, was retrospectively obtained within 1 year. To examine the potential association between nutrition indicators and pneumonia risk among stable schizophrenia patients, we employed a logistic regression analysis.ResultsThe pneumonia incidence among all stable schizophrenia patients was 10.14%, and there were no statistically significant difference between sexes (male vs. female, 10.63% vs. 9.44%, P = 0.687). Based on the univariate analysis of nutrition indicators and pneumonia, female patients exhibited a strong correlation between serum albumin and pneumonia (P = 0.022). Furthermore, we adjusted for potential influencing factors of pneumonia infection, and confirmed that only serum albumin was linked to pneumonia risk in female stable schizophrenia patients (odds ratio = 0.854, 95% CI: 0.749–0.975, P = 0.02).ConclusionsBased on our analysis, serum albumin was strongly correlated with pneumonia risk in female stable schizophrenia patients.
