Abstract

Objectives

To examine the association between social mobility and tooth loss in adults from the 1982 Pelotas Birth Cohort Study and whether race modifies this association.

Methods

The Oral Health Study used data from 541 individuals who were followed up to 31 years of age. Social mobility, composed of the participants' socioeconomic position (SEP) at birth and at age 30, was categorized as never poor, upwardly mobile, downwardly mobile and always poor. The outcome was the prevalence of at least one tooth lost due to dental caries when the participants were examined at 31 years of age. The effect modifier was race (Black/Brown versus white people). Log-binomial regression models were used to estimate crude and sex-adjusted prevalence ratios (PR) and to determine whether the association varied with race. Statistical interactions were tested using an additive scale.

Results

The prevalence of any tooth loss was 50.8% (n = 274). In social mobility groups, the prevalence of at least one tooth lost in the never-poor group was about 31% points higher for Black/Brown (68.2%) than for white people (37.4%). Antagonistic findings were found for the interaction between race and social mobility (Sinergy Index = 0.48; 95% CI 0.24, 0.99; and relative excess of risk due to the interaction = −1.38; 95% CI −2.34, −0.42), suggesting that the observed joint effect of race and social mobility on tooth loss was lower than the expected sum of these factors. The estimates for Black/Brown people were smaller for those who were always poor during their lives, relative to their white counterparts.

Conclusions

The findings suggest a higher prevalence of at least one tooth lost among people in the downward mobile SEP group and Black/Brown people. Greater racial inequity was found among Black/Brown people who had never experienced episodes of poverty, with Black/Brown people having a greater prevalence of at least one tooth lost than their white counterparts.

社会流动性对不同种族成年后牙齿脱落的不同影响：1982 年佩洛塔斯出生队列研究。

目的：研究 1982 年佩洛塔斯出生队列研究中成年人的社会流动性与牙齿脱落之间的关系，以及种族是否会改变这种关系：研究 1982 年佩洛塔斯出生队列研究中成年人的社会流动性与牙齿脱落之间的关系，以及种族是否会改变这种关系：口腔健康研究使用了 541 人的数据，这些人一直被跟踪到 31 岁。社会流动性由参与者出生时和 30 岁时的社会经济地位（SEP）组成，分为从不贫穷、向上流动、向下流动和始终贫穷。结果是参与者在 31 岁接受检查时至少有一颗牙齿因龋齿而脱落。影响因素是种族（黑人/棕色人种与白人）。对数二项式回归模型用于估算粗略和性别调整后的患病率比（PR），并确定相关性是否随种族而变化。统计交互作用使用加法量表进行测试：任何牙齿缺失的患病率为 50.8%（n = 274）。在社会流动性群体中，从未贫穷群体中至少有一颗牙齿脱落的比例，黑人/棕色人种（68.2%）比白人（37.4%）高出约 31%。种族和社会流动性之间的交互作用发现了对立的结果（Sinergy 指数 = 0.48；95% CI 0.24，0.99；交互作用导致的相对超额风险 =-1.38；95% CI -2.34，-0.42），表明观察到的种族和社会流动性对牙齿脱落的共同影响低于这些因素的预期总和。相对于白人而言，黑人/棕色人种中那些一生都处于贫困状态的人的估计值较小：结论：研究结果表明，在社会经济地位下降群体和黑人/棕色人种中，至少有一颗牙齿脱落的发生率较高。在从未经历过贫困的黑人/棕种人中发现了更大的种族不平等，黑人/棕种人至少掉一颗牙的发生率高于白人。

期刊介绍： The aim of Community Dentistry and Oral Epidemiology is to serve as a forum for scientifically based information in community dentistry, with the intention of continually expanding the knowledge base in the field. The scope is therefore broad, ranging from original studies in epidemiology, behavioral sciences related to dentistry, and health services research through to methodological reports in program planning, implementation and evaluation. Reports dealing with people of all age groups are welcome. The journal encourages manuscripts which present methodologically detailed scientific research findings from original data collection or analysis of existing databases. Preference is given to new findings. Confirmations of previous findings can be of value, but the journal seeks to avoid needless repetition. It also encourages thoughtful, provocative commentaries on subjects ranging from research methods to public policies. Purely descriptive reports are not encouraged, nor are behavioral science reports with only marginal application to dentistry. The journal is published bimonthly.
