Samenvatting

Background: This cross-sectional study is a follow-up study designed to investigate the relationship between the sense of smell and the nutritional status, especially in regard to drugs that may influence smell and taste and eating habits in geriatric patients who visited the geriatric diagnostic day clinic or outpatient clinic of the Slotervaart Hospital located in Amsterdam. This study took place between August and December 2013. Materials and methods: The Mini Nutritional Assessment-Short Form (MNA-SF) was used to assess the nutritional status. To investigate the smell function of the participants the Sniffin’ Sticks – Screening 12 test was assessed in 138 participants (91 females, mean age 80.9, ± 7.6). Results: Of the participants 44% were at risk of malnutrition, 16% were malnourished and 40% had a normal nutritional status. The smell test showed that 56% of the participants had reduced sense of smell (hyposmic), 32% had absence of smell (anosmic) and 12% had a normal sense of smell (normosmic). A strong negative significant relation between the sense of smell and nutritional status (p= 0.01) was shown by a linear regression analysis. There was no significant relation found between the sense of smell and medication that can affect smell or smell and taste. There was a weak significant correlation between the results of the smell test and the own assessment of the smell function (r= 0.310, p= <0.001). Conclusions: This study shows that there is a relation between the sense of smell and nutritional status. Medication with potential effect on smell or taste and smell and eating habits do not have significant effects on the sense of smell and nutritional status. Geriatric patients can poorly assess their own smell function. Key words: Sense of smell, nutritional status, geriatric patients, eating habits, medication.
