Most studies on social mobility and oral health have focused on movement between generations (intergenerational mobility) rather than movement within an individual's own lifetime (intragenerational mobility). The aim of this study was to investigate the association between intragenerational social mobility from early to middle adulthood and self-rated oral health.
This study used data from 6524 participants of the 1970 British Birth Cohort Study, an ongoing population-based birth cohort of individuals born in England, Scotland and Wales. Participants' socioeconomic position was indicated by occupational social class at age 26 and 46 years (the first and latest adult waves, respectively). Self-rated oral health was measured at age 46 years. The association between social mobility and adult oral health was assessed using conventional regression models and diagonal reference models, adjusting for gender, ethnicity, country of residence and residence area.
Over a fifth of participants (22.2%) reported poor self-rated oral health at age 46 years. In conventional regression analysis, the odds ratios for social mobility varied depending on whether they were adjusted for social class of origin or destination. In addition, all social trajectories had greater odds of reporting poor oral health than non-mobile adults in class I/II. In diagonal reference models, both upward (Odds Ratio 0.79; 95% CI 0.63-0.99) and downward mobility (0.90; 95% CI 0.71-1.13) were inversely associated with poor self-rated oral health. The origin weight was 0.48 (95% CI 0.33-0.63), suggesting that social class of origin was as important as social class of destination.
This longitudinal analysis showed that intragenerational social mobility from young to middle adulthood was associated with self-rated oral health, independent of previous and current social class.
大多数关于社会流动和口腔健康的研究都集中在代际之间的流动（代际流动），而不是个体自身生命周期内的流动（同代内流动）。本研究旨在探讨从中年到中年的同代内社会流动与自我评估的口腔健康之间的关联。
本研究使用了 1970 年英国出生队列研究的 6524 名参与者的数据，这是一项针对英格兰、苏格兰和威尔士出生的个体的基于人群的出生队列研究。参与者的社会经济地位由 26 岁和 46 岁时的职业社会阶层（分别为第一个和最新的成人波）来表示。46 岁时测量了自我评估的口腔健康状况。使用传统回归模型和对角线参考模型评估社会流动与成人口腔健康之间的关联，调整性别、种族、居住国家和居住地区。
超过五分之一的参与者（22.2%）报告在 46 岁时口腔健康状况不佳。在传统回归分析中，社会流动的优势比取决于是否调整了原籍社会阶层或目的地社会阶层。此外，与 I/II 级非流动成年人相比，所有社会轨迹报告口腔健康状况不佳的可能性都更大。在对角线参考模型中，向上（优势比 0.79；95%置信区间 0.63-0.99）和向下（0.90；95%置信区间 0.71-1.13）流动都与自我评估的口腔健康不良呈负相关。原点权重为 0.48（95%置信区间 0.33-0.63），表明原籍社会阶层与目的地社会阶层同样重要。
这项纵向分析表明，从中年到中年的同代内社会流动与自我评估的口腔健康有关，与以前和现在的社会阶层无关。
