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.
以往的研究无法确定高龄对口腔健康的影响，因为这些研究纳入的75岁以上受试者相对较少，尤其是男性。在本研究中，从加拿大不列颠哥伦比亚省温哥华市的选民名单中，选取了一个不成比例的分层随机样本，样本为70岁以上且独立生活的受试者。521名老年人的样本结构为在三个5岁年龄组中提供数量相近的男性和女性。所有受试者都接受了访谈，其中255名代表了相似年龄和性别的分布，接受了检查，以调查衰老对口腔健康和相关行为的影响。在双变量分析中，年龄和性别与口腔健康或口腔问题均无显著关联。上一年度牙科服务的使用与女性和年轻受试者相关，而男性和老年受试者通常仅在疼痛时才去看牙医。多变量模型中的逻辑回归证实了天然牙在预测牙科服务使用方面的重要性（将预测准确率从60%提高到73%）。其他模型在预测口腔问题（从64%提高到70%）或口腔健康（从56%提高到60%）方面的改善效果较差。总体而言，该研究表明，独立生活的老年人的年龄和性别对其早年确立的口腔健康或相关行为几乎没有直接影响。
