•The SNAQ was reliable and valid as an appetite screening tool in community-dwelling Turkish elderly.•The cut-off value of the SNAQ, according to both the MNA long and short forms, was 14 (sensitivity; 50%, 50% and specificity; 84%, 82%, respectively).•SNAQ score of ≤14 was significantly related with depression, IADL dependency and frailty. The aim of this study was to determine a cut-off value for the SNAQ according to both the MNA long and MNA short forms and to assess whether the SNAQ can predict malnutrition or risk of malnutrition in the elderly. Nutritional status was assessed both by the Mini Nutritional Assessment (MNA) long and short forms. All demographic characteristics, mental status, depressive mood, functional status, and frailty were determined. Receiver operating characteristic (ROC) curves were used to calculate the cut-off of the SNAQ according to both the MNA long and short forms for malnutrition or risk of malnutrition. Reliability and validation of the SNAQ was analysed. We included 905 community-dwelling elderly, but those with middle-stage dementia (MMSE score
