Samenvatting

Background: This cross-sectional study was designed to investigate the relationship between the sense of smell and the nutritional status in geriatric patients who visited the geriatric diagnostic day clinic or outpatient clinic of the Slotervaart Hospital, a teaching hospital located in Amsterdam. The study was carried out between March and May 2012. Materials and methods: Nutritional assessment was performed by 88 participants (61 females, mean age 82.3 ± 6.5 years) using the Mini Nutritional Assessment-Short Form (MNA-SF). The Sniffin’ Sticks - Screening 12 Test was used to investigate the olfactory function of 75 participants (54 females, mean age 81.7 ± 6.6 years). Results: Forty-nine percent of the participants were at risk of malnutrition, 16% were malnourished and 35% had a normal nutritional status. More than half of the participants (57.3%, n= 75) appeared to be hyposmic, 28.0% appeared to be anosmic and 14.7% had a normal sense of smell. Linear regression analysis demonstrated a strongly significant relationship (p= 0.004) between the sense of smell and nutritional status. Corrected for possible cofounders the relationship remains significant at a p-value of 0.005. Conclusions: This study showed that the sense of smell is related to nutritional status in this study population. Our results confirm that the loss of smell and malnutrition are common problems among geriatric patients.
