Self-perceived oral health status, psychological well-being, and life satisfaction in an older adult population.

Numerous studies have demonstrated that many older adults have problems chewing, pain, difficulties in eating, and problems in social relationships because of oral disorders. However, it is not clear if these functional and psychosocial outcomes affect broader psychological well-being and life satisfaction. Consequently, this paper begins to address the question, 'Does poor oral health compromise the quality of life?'. Initial cross-sectional analyses used data derived from the seven-year follow-up of the Ontario Study of the Oral Health of Older Adults. As at baseline and three-year follow-up, oral health was measured by self-ratings of oral health and five oral health indices. Psychological well-being and life satisfaction were assessed according to the Morale Index, the Perceived Life Stress Questionnaire, The Life Satisfaction Scale, and the General Health Questionnaire. All oral health variables were significantly associated with scores from the first three of these measures in the expected direction. These associations remained after we controlled for other potential influences on the quality of life. In addition, prospective analysis indicated that self-perceived oral health at three years had a significant independent effect on psychological well-being and life satisfaction at seven years. These results suggest that poor self-perceived oral health and relatively poor quality of life co-exist in the same subgroup of older adults.
