Overview

Systematic review highlights strong associations between factors like body mass index and malnutrition in nursing home residents, suggesting improved nutritional strategies.

Key Points

  • Higher body mass index was associated with reduced risk of malnutrition, with a pooled odds ratio of 0.74.
  • Dependence on activities of daily living significantly increased malnutrition risk, showing a pooled odds ratio of 3.70.
  • Eating less than 50% of offered food portions strongly correlated with malnutrition, indicated by a pooled odds ratio of 3.56.
  • Dementia was significantly associated with malnutrition, demonstrated by a pooled odds ratio of 1.98.
