This study is carried out in order to determine the nutrition habits and health conditions of old people living in nursing homes. The participants are 53 old people aged 65 and above- who are living in nursing homes depending on Social Services and Child Protection Society in Ankara. To determine the nutrition conditions of old people, a Mini-Nutritional Assessment (MNA) test has been used and some parameters of blood (glucose, cholesterol, triglyceride, albumin, urine) have been measured. It is stated that the most frequently seen disease of old people for both genders is hypertension. According to the results of MNA test, it is seen that higher than the half of the men (56%) and 46.4% of women are under the risk of malnutrition. In terms of MNA, the blood biochemistry parameters of the old people having well-nutrition are closer to the reference values than the others that are under the risk of malnutrition. As a result of this study, it is concluded that this is a suitable way to be assessed the nutrition conditions of the old people living in the nursing homes by dieticians via MNA test in routine periods.
