Older people with swallowing disorders are faced with the risk of malnutrition and this affects the quality of life adversely. The aim of this study; determination of nutritional status in elderly with dysphagia, examining the relationship between food consumption and masticatory performance, as well as the determination of nutrient deficiency and to examine the effect of dysphagia on quality of life in and investigate malnutrition or risk of malnutrition in elderly with swallowing disorders. The study was carried out on 55 (27 men, 28 women) patients with dysphagia at Swallowing Disorders Research and Practice Center and 62 (24 men, 38 women) healthy elderly people as control group at the Geriatrics Clinic in Hacettepe University in April 2015- April 2016. General characteristics, malnutrition status, oral health status, physical activity level and a questionnaire assessing their quality of life were applied all elderly. Also, food consumption records (1 day) and some anthropometric measurements were taken of all the elderly. Masticatory performances of the elderly were evaluated by a special gum. At the end of the study, it is determined that 69.1% of patients had bad, 27.3% of patients had normal and 3.6% of patients had a better masticatory performance. In control group, this case is accordingly 53.2%, 30.6% and 16.1% (p<0.05). According to Mini Nutritional Assessment (MNA), 49.1% of patients were malnourished and 45.4% of patients are at risk of malnutrition. In the control group, it is discovered that 9.7% of the elderly were malnourished and 41.9% of the elderly were at the risk of malnutrition (p<0.001). Body weight, body mass index (BMI), waist circumference, mid-upper arm circumference and handgrip strength in men with swallowing disorders were different from the control group (p<0.05). When women with swallowing disorder compared with women in the control group; mid-upper arm circumference, femur bicondylar size and handgrip strength were different (p<0.05). Male elderly in the case group, energy, protein, fiber, vitamin A, vitamin B1, vitamin B2, niacin, vitamin B6, folic acid, calcium, magnesium and zinc; in female elderly; energy, protein, fiber, vitamin B1, niacin, vitamin B6, folic acid, calcium, magnesium, iron and zinc intakes were considered as inadequate. Regarding the relationship between Geriatric Oral Health Assessment İndex (GOHAI) and Eating Assessment Tool (EAT-10), EAT-10 and BMI, EAT-10 and Understanding of Quality of Life (SWAL-QOL) it is found that there was a strong correlation (p<0.05). MNA and GOHAI, MNA and EAT-10, MNA and BMI, MNA and BI, MNA and masticatory performance, MNA and SWAL-QOL, GOHAI and Barthel Index (BI), GOHAI and SWAL-QOL, GOHAI and masticatory performance was observed a moderate correlation (p<0.05). In conclusion, regarding MNA, it is discovered that elderly with swallowing disorders had a high risk of malnutrition and there was a strong relationship between the quality of life and swallowing disorders. Therefore, it is crucial to know the potential changes in nutritional status after diagnosed with swallowing disorders. Moreover, older people should be followed by a dietitian and a healthy and balanced diet in accordance with their specific requirements consumption should be provided for the elderly at every stage.
