No studies have taken a multigenerational approach to the study of oral health inequalities. This study investigated whether grandparents' social class was associated with adult grandchildren's oral health.
Data from the 1958 National Child and Development Study (NCDS) and the 1970 British Cohort Study (BCS) were analysed. Cohort members' occupational social class and persistent trouble with mouth, teeth or gums in the past 12 months were reported at ages 33 years in the NCDS and 26 years in the BCS. Information on grandparents' and parents' social class was reported by the cohort members' mothers during childhood. The association between grandparents' social class and cohort members' report of persistent trouble with mouth, teeth or gums was tested in marginal structural models (MSMs).
Data from 9853 NCDS and 6487 BCS participants were analysed. Grandparents' social class was not associated with cohort members' report of persistent trouble with teeth, gums or mouth in the NCDS sample (odds ratios of 1.25 [95% Confidence Interval: 0.95-1.65] for social class IV/V and 1.12 [95% CI: 0.76-1.64] for social class IIINM-M relative to social class I/II) or the BCS sample (odds ratios of 0.98 [95% CI: 0.68-1.43] for social class IV/V and 0.88 [95% CI: 0.67-1.16] for social class IIINM-M relative to social class I/II).
This study provided no support for an independent association between grandparents' social class and adult grandchildren's oral health.
目前尚无研究采用多世代方法来研究口腔健康不平等问题。本研究旨在探讨祖辈的社会阶层是否与成年孙辈的口腔健康有关。
本研究分析了 1958 年全国儿童发展研究（NCDS）和 1970 年英国队列研究（BCS）的数据。在 NCDS 中，队列成员在 33 岁时报告了过去 12 个月内口腔、牙齿或牙龈的持续问题，在 BCS 中，队列成员在 26 岁时报告了过去 12 个月内口腔、牙齿或牙龈的持续问题。在童年时期，由队列成员的母亲报告了祖辈和父母的社会阶层信息。在边际结构模型（MSM）中检验了祖辈的社会阶层与队列成员报告的口腔、牙齿或牙龈持续问题之间的关联。
本研究共分析了 9853 名 NCDS 和 6487 名 BCS 参与者的数据。在 NCDS 样本中，祖辈的社会阶层与队列成员报告的牙齿、牙龈或口腔持续问题无关（社会阶层 IV/V 与 I/II 相比的比值比为 1.25 [95%置信区间：0.95-1.65]，社会阶层 III/NM-M 与 I/II 相比的比值比为 1.12 [95%置信区间：0.76-1.64]），在 BCS 样本中也无相关性（社会阶层 IV/V 与 I/II 相比的比值比为 0.98 [95%置信区间：0.68-1.43]，社会阶层 III/NM-M 与 I/II 相比的比值比为 0.88 [95%置信区间：0.67-1.16]）。
本研究未提供祖辈的社会阶层与成年孙辈的口腔健康之间存在独立关联的证据。
