Purpose: Low socioeconomic status (SES) and minority race/ethnicity are both associated with chronic stress and co-vary in American society. As such, these factors are often used synonymously, without clear theoretical conceptualization of their roles in the development of stress-related health disparities. This study theorized that race/ethnicity and SES reflect social disadvantage, which is the underlying factor in the development of stress-related illness, and examined how social disadvantage, defined in terms of both race/ethnicity and SES, influences adolescents' stress.
Methods: This is a cross-sectional school-based study of 1209 non-Hispanic black and white 7th-12th graders from a single Midwestern metropolitan public school district. Each student completed a questionnaire and a parent provided SES information. Race/ethnicity was obtained from school records. Linear regression analyses determined the influence of race/ethnicity and SES to stress. Race/ethnicity and presence or absence of at least one parent who graduated from college were used to define four subgroups for within-group analyses.
Results: Stress was higher among black students, those from lower SES families, and those with lower perceived SES. In subgroup analyses, neither race nor SES maintained their independent associations with stress among socially disadvantaged groups. Black race was not associated with stress among those without a college-educated parent, and parent education did not influence stress among black students. In contrast, among more socially advantaged groups, both SES and race explained variation in adolescents' stress.
Conclusions: Social disadvantage is associated with increased stress, regardless of whether disadvantage is defined in terms of race or SES. This suggests that race and SES measure adversity in the social environment, and therefore, serve as risk markers, rather than risk factors. Future research should focus on the experience of adversity, which is reflected by these social characteristics, and the processes by which it operates.
