Discrimination and bladder health among women in the CARDIA cohort study: Life course and intersectionality perspectives.

ABSTRACT

OBJECTIVE: This study examines whether discriminatory experiences are associated with lower urinary tract symptoms (LUTS) and their impact among 972 women in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study, which recruited participants from 4 cities in the United States. METHOD: Exposure to discrimination was assessed 3 times (1992-93, 2000-01, 2010-11) and averaged across assessments. Participants separately reported whether they experienced discrimination on the basis of their gender, race or color, and socioeconomic position or social class. For each social identity, discrimination was assessed in 6-7 settings (e.g., when getting a job, medical care, or housing). At different time points, women who reported discriminatory experiences for a given social identity were asked how frequently the discrimination occurred and how stressful experience(s) were. Following the 2010-11 assessment, data on LUTS and their impact were collected. Women were classified into bladder health versus mild, moderate, or severe symptoms/impact clusters. RESULTS: More Black than White women reported discriminatory experiences across all social identities and most settings. Perceived stress of discriminatory experiences did not differ between Black and White women. In analyses stratified by race and social identity, White women reported LUTS/impact with discriminatory experiences in more settings, more frequent discriminatory experiences across settings, and each additional social identity for which discrimination was experienced. Black women reported LUTS/impact with more frequent discriminatory experiences across settings. For Black women, greater perceived stress of both gender and race discrimination were associated with LUTS/impact. For White women, only greater perceived stress of race discrimination was associated with LUTS/impact. CONCLUSIONS: This is one of the first studies to examine discrimination in relation to LUTS/impact. Additional research is needed to better understand differences in how discriminatory experiences based on potentially intersecting identities may be related to bladder health among women.
