To investigate the mediation effect of socioeconomic position and racial discrimination in the association between race/color and incidence of hypertension in 4-years follow up.
We included 8,370 participants of the Longitudinal Study of Adult Health (ELSA-Brasil). A latent variable was constructed to represent socioeconomic position (SEP). The perception of discrimination was measured through an adaptation of the Lifetime Major Events Scale; and hypertension was defined using standard criteria. We investigated Body Mass Index (BMI) due to its role in proximal risk for hypertension. To investigate the mediating role of SEP and racial discrimination, we used structural equation modeling.
SEP had a direct and negative effect on HT incidence (HT incidence increased in worse SEP categories), while the effect of BMI on HT was direct and positive. We did not find significant direct effects of race/color and racial discrimination on HT. As for indirect effects, we observed associations between race/color and HT only through SEP mediation.
According to our results, race/color is indirectly related to HT incidence, mediated by SEP. Racial discrimination was not a mediator in the relationship between race/color and HT in the follow-up period.
在 4 年的随访中，调查社会经济地位和种族歧视在种族/肤色与高血压发病率之间的关系中的中介作用。
我们纳入了 8370 名成年人健康纵向研究（ELSA-Brasil）的参与者。构建了一个代表社会经济地位（SEP）的潜在变量。通过生活中重大事件量表的改编来衡量歧视的感知；并使用标准标准来定义高血压。我们研究了身体质量指数（BMI），因为它在高血压的近端风险中起作用。为了调查 SEP 和种族歧视的中介作用，我们使用结构方程模型。
SEP 对 HT 发病率有直接的负向影响（SEPCAT 类别越差，HT 发病率越高），而 BMI 对 HT 的影响是直接正向的。我们没有发现种族/肤色和种族歧视对 HT 有显著的直接影响。至于间接效应，我们仅观察到种族/肤色与 HT 之间的关联通过 SEP 中介。
根据我们的结果，种族/肤色与 HT 发病率呈间接相关，由 SEP 介导。在随访期间，种族歧视不是种族/肤色与 HT 之间关系的中介因素。
