Oral health-related quality of life and life-space mobility in community-dwelling older adults.

OBJECTIVES

To quantify the associations between measures of oral health-related quality of life (OHRQoL) and life-space mobility (LSM) in community-dwelling older adults.

DESIGN

Cross-sectional study using a 54-item OHRQoL questionnaire.

SETTING

Five counties in central Alabama: Jefferson and Tuscaloosa (urban), and Bibb, Hale, and Pickens (rural).

PARTICIPANTS

The 288 dental study volunteers were recruited from participants in the University of Alabama at Birmingham Study of Aging, a longitudinal study of mobility in community-dwelling adults aged 65 and older.

MEASUREMENTS

Participants completed an in-home interview about their OHRQoL and LSM. Life-space was assessed by asking questions about where and how often participants got to areas ranging from the home to beyond town and the degree of independence in getting there. Unadjusted and adjusted regression models were used to quantify associations between OHRQoL and LSM. Other factors examined were age, race, sex, income, education, residence, transportation difficulty, marital status, depressive symptoms, and comorbidity.

RESULTS

Unadjusted and adjusted analyses suggested significant associations between OHRQoL and LSM in oral functional limitation, oral pain and discomfort, oral disadvantage, and self-rated oral health.

CONCLUSION

OHRQoL decrements that participants reported were associated with less LSM, suggesting that perceptions of oral well-being have a significant effect on mobility and the social participation of older adults.
