Abstract
OBJECTIVES: The purpose was to assess the association between neck circumference, dysphagia, and undernutrition in elderly individuals requiring long-term care. DESIGN: Cross-sectional study. SETTING: Geriatric health services facilities, acute hospitals, and the community. PARTICIPANTS: Elderly individuals ≥65 years of age with dysphagia or possible dysphagia (N=385). MEASUREMENTS: Neck circumference, the Dysphagia Severity Scale (DSS) and the Mini Nutritional Assessment Short Form (MNA-SF). RESULTS: Participants included 130 males and 255 females with a mean age (± standard deviation) of 83 ± 8.0 years. Sixty-six were in acute hospitals, 195 were in geriatric health services facilities, and 124 were community-dwelling. The mean neck circumference in males and females was 37.1 ± 3.0 cm and 33.3 ± 3.3 cm, respectively. Based on the DSS, 81 participants were within normal limits, 137 had dysphagia without aspiration, and 167 had dysphagia with aspiration. The MNA-SF revealed that 173 were malnourished, 172 were at risk of malnutrition, and 40 had a normal nutritional status. Neck circumference was not significantly correlated with the DSS (r=-0.080) but was significantly correlated with the MNA-SF (r=0.183) in the Spearman rank correlation analysis. In the logistic regression, neck circumference was not independently associated with the DSS after adjusting for the MNA-SF, the Barthel Index, age, sex, setting, and cerebrovascular disorders. However, the multiple regression analysis showed that neck circumference had an independent effect on the MNA-SF after adjusting for the Barthel Index, age, sex, setting and cerebrovascular disorders. CONCLUSIONS: Neck circumference is not associated with dysphagia but with undernutrition in elderly individuals requiring long-term care.
