Accordingly, SNAQ 28.7% of elderly were risk at loss of weight. Health related quality of life scores of women were significantly lower than men. Good nutritional (MNA-SF) and good appetite (SNAQ) status, increased 1.69, 1.48 fold in the mental component summary scale scores respectively. SNAQ was the best determinant of physical component summary scale score had the greatest positive effect, good appetite status increased approximately 2.2 fold in physical scores. Polypharmacy and high BMI decreased health related quality of life in elderly.
