Influence of age and gender on oral health and related behaviour in an independent elderly population.
Previous studies have been unable to determine the influence of advanced age on oral health because they included relatively few subjects, particularly men, over 75 yr of age. In this study a disproportionate and stratified random sample of subjects over 70 yr and living independently was selected from a list of voters in Vancouver, B.C. The sample of 521 elders was structured to provide similar numbers of men and women in three 5-yr age-groups. All of the subjects were interviewed, and 255 of them, representing a similar distribution of age and gender, were examined to investigate the influence of aging on oral health and related behaviour. In bivariate analyses neither age nor gender was associated significantly with oral health or complaints. The use of dental services during the preceding year was associated with female and younger subjects, while men and older subjects usually went to dentists only to relieve pain. Logistic regression in a multivariate model confirmed the importance of natural teeth in predicting the use of dental services (by improving the prediction from 60% to 73%). Other models offered less useful improvements in predicting complaints (64% to 70%) or oral health (56% to 60%). Overall the study demonstrates that the age and gender of independent elders have very little direct influence on the oral health or related behaviour established early in life.
