Background and aims A high proportion of older care recipients (CRs) face malnutrition and risk of malnutrition, affecting their functional abilities and posing challenges for caregiving. The aim of this study was to assess the risk for malnutrition among older CRs and the associated characteristics of both CRs and family caregivers (FCs) with nutritional status of CRs.

Methods A cross-sectional study consisted of 120 CRs (≥65 years) and their 118 FCs (≥60 years). Nutritional status was assessed with the Mini Nutritional Assessment (MNA).

Results The majority (63%) of the CRs had a risk of malnutrition (MNA score 17–23.5), and 7% had malnutrition (MNA score <17). The CRs had significantly lower MNA scores compared to their FCs (p < 0.001). The multivariate linear regression analysis showed that CRs' higher number of comorbidities (B = −0.37, p = 0.013) and higher P-hs-CRP (B = −0.10, p = 0.047) were associated with their decreased MNA scores. There was a positive association between CRs' hand grip strength (B = 0.11, p = 0.004) and FCs’ MNA scores (B = 0.41, p = 0.004) with MNA scores of the CRs.

Conclusion Malnutrition and risk of malnutrition are common concerns in older CRs, especially those with a higher number of comorbidities and low-grade inflammation. Regular assessment of the nutritional status of both older CRs and FCs is justified, as FCs’ better nutritional status is associated with better nutritional status of CR.
