Interpersonal abuse and alcohol use among African American young women: the mediating role of emotion dysregulation

Posttraumatic Stress, Alcohol Use, and Alcohol Use Motives among Non-Hispanic Black/African American College Students: The Role of Emotion Regulation

OBJECTIVE

The associations between posttraumatic stress disorder (PTSD) symptom severity, alcohol use, and alcohol use motives are well-established. Emotion regulation difficulties have been implicated in the association between PTSD symptoms and alcohol use. A dearth of empirical work, however, has examined these associations among Black/African American college students, a population with high prevalence of exposure to potentially traumatic events, PTSD symptomatology, and alcohol-related consequences.

METHODS

This study examined PTSD symptoms, emotion regulation difficulties, and alcohol use severity and motives among a sample of Black/African American trauma-exposed college students (N = 282; 77.4% identified as female; M age = 22.36, SD = 4.71).

RESULTS

PTSD symptom severity was related to alcohol use and coping and conformity motives for alcohol use through heightened emotion regulation difficulties. Findings were significant above and beyond the effects of trauma load (i.e., number of potentially traumatic event types experienced).

CONCLUSIONS

This study extends past work to an understudied population and contributes to groundwork for culturally informed interventions.

Racial disparities in triple negative breast cancer: toward a causal architecture approach

BACKGROUND

Triple negative breast cancer (TNBC) is an aggressive subtype of invasive breast cancer that disproportionately affects Black women and contributes to racial disparities in breast cancer mortality. Prior research has suggested that neighborhood effects may contribute to this disparity beyond individual risk factors.

METHODS

The sample included a cohort of 3316 breast cancer cases diagnosed between 2012 and 2020 in New Castle County, Delaware, a geographic region of the US with elevated rates of TNBC. Multilevel methods and geospatial mapping evaluated whether the race, income, and race/income versions of the neighborhood Index of Concentration at the Extremes (ICE) metric could efficiently identify census tracts (CT) with higher odds of TNBC relative to other forms of invasive breast cancer. Odds ratios (OR) and 95% confidence intervals (CI) were reported; p-values < 0.05 were significant. Additional analyses examined area-level differences in exposure to metabolic risk factors, including unhealthy alcohol use and obesity.

RESULTS

The ICE-Race, -Income-, and Race/Income metrics were each associated with greater census tract odds of TNBC on a bivariate basis. However, only ICE-Race was significantly associated with higher odds of TNBC after adjustment for patient-level age and race (most disadvantaged CT: OR = 2.09; 95% CI 1.40-3.13), providing support for neighborhood effects. Higher counts of alcohol and fast-food retailers, and correspondingly higher rates of unhealthy alcohol use and obesity, were observed in CTs that were classified into the most disadvantaged ICE-Race quintile and had the highest odds of TNBC.

CONCLUSION

The use of ICE can facilitate the monitoring of cancer inequities and advance the study of racial disparities in breast cancer.
