Key Points

This study evaluates the incidence and factors associated with malnutrition among older individuals in nursing homes.
Systematic review of observational studies on malnutrition in nursing homes.
Data collected from multiple databases including PubMed, Embase, and CNKI.
A total of 25 studies with 51,915 cases were included for analysis.
Malnutrition prevalence in nursing homes was found to be 22% (95% CI: 0.19–0.25).
Key factors related to malnutrition included age (OR = 2.39, 95% CI: 1.87–3.07) and disabilities in activities of daily living (OR = 3.37, 95% CI: 1.90–5.96).
Multiple disease-related factors, such as dementia (OR = 1.63, 95% CI: 1.54–1.74) and frailty (OR = 3.37, 95% CI: 1.22–9.29), significantly increased the risk of malnutrition.
