Oral health-related quality of life and nutritional status

J Public Health Dent. 2008 Spring;68(2):88-93. doi: 10.1111/j.1752-7325.2007.00082.x.


Objectives: This study examines whether oral health-related quality of life (OHRQoL) is associated with malnutrition risk in the elderly.

Methods: A cross-sectional study was designed using a representative sample of Spaniards over 65 years old. Data on sociodemographics and oral health status were gathered by interview and examination. Oral health-related quality of life was evaluated using the Geriatric Oral Health Assessment Index (GOHAI), and malnutrition risk using the Mini Nutritional Assessment (MNA).

Results: The final sample included 2,860 elderly, 41.7 percent males and 58.3 percent females, with a mean age of 73.7 +/- 6.8 years. Mean GOHAI score was 52.1 +/- 7.2, with 70.7 percent of the sample needing oral health care according to this index. The mean MNA score was 24.0 +/- 3.31; 3.5 percent of the elderly were malnourished, 31.5 percent were at risk of malnutrition, and 65.0 percent were considered adequately nourished. A strong association was found between mean GOHAI and MNA scores.
