Measuring and Eliminating Racism and Racial Disparities in MCH:  The Need for New Paradigms

This study explores the relationship between African American women's lifetime exposure to racial discrimination and preterm very low birth weight infants, using a case-control design. The findings suggest that maternal lifetime exposure to interpersonal racism in multiple domains is associated with lower infant birth weight.

  10. Race “Race” is not a biological construct that reflects innate differences, but a social construct that precisely captures the impacts of racism. (Jones, AJPH, 2000)

  11. RESEARCH QUESTION To what extent are African-American women’s lifetime exposures to perceived interpersonal racial discrimination a risk factor for preterm-VLBW?

  12. METHODS • Case-control study of African-American infants admitted to Children’s Memorial, University of Chicago, and Cook County Hospitals 11/97-10/00. • Cases: mothers of very low birth weight (<1500g, VLBW), preterm (< 37wks) infants. • Controls: mothers of non-low birth weight ( >2500g, non-LBW), term infants. • Case to control ratio of 1:2; $10.00 participation reward offered to all eligible subjects.

  13. METHODS • Structured Questionnaire: - lifetime exposure to interpersonal racial discrimination in 5 domains: “getting work”, “at work”, “at school”, “getting service at a restaurant / store, “getting medical care” (Krieger, 1990). - full-time employed women were asked an additional 20 questions regarding lifetime and past year exposure to interpersonal racial discrimination at their primary place of employment (McNeilly, 1996).

  14. METHODS • Responses were dichotomized after data collection into none (“none” or “less than once/ year”) or regularly (“few times/year”, “few times/month”, “at least once/week”, and “nearly everyday”). • Maternal age, education, marital status, income, prenatal care usage, parity, cigarette smoking, alcohol intake, and social support. • Stratified and multivariate logistic regression analyses were performed.

  15. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM IN 1 OR MORE DOMAINS AND INFANT BIRTH WEIGHT(Collins et al, AJPH, 2004)

  16. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM IN 3 OR MORE DOMAINS AND INFANT BIRTH WEIGHT(Collins et al, AJPH, 2004)

  17. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM, MATERNAL AGE, AND INFANT BIRTH WEIGHT

  18. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM, MATERNAL EDUCATION, AND INFANT BIRTH WEIGHT

  19. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM, PRENATAL CARE, AND INFANT BIRTH WEIGHT

  20. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM, CIGARETTE SMOKING, AND INFANT BIRTH WEIGHT

  21. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM , SOCIAL SUPPORT, AND INFANT BIRTH WEIGHT

  22. LOGISTIC REGRESSION(Collins et al, AJPH, 2004) • Unadjusted and adjusted OR of VLBW for maternal lifetime exposure to interpersonal racial discrimination in 1 or more domains were 1.9 (1.2-3.1) and 2.3 (1.1-3.6), respectively. • Unadjusted and adjusted OR of VLBW for maternal lifetime exposure to interpersonal racial discrimination in 3 or more domains were 2.7 (1.3-5.4) and 2.6 (1.2-5.3), respectively.

  23. MATERNAL LIFETIME EXPOSURE TO INTERPERSONAL RACISM AT THE WORKPLACE AND INFANT BIRTH WEIGHT • “Because you are African-American, you are assigned jobs no one else will do”. OR=1.7 (0.7-4.3) • “Whites often assume that you work in a lower class job than you do and treat you as such”. OR=2.3 (1.0-5.1 • “You are treated with less dignity and respect than you would be if you were white. OR=2.0 (0.8-4.3) • “You are watched more closely than others because of your race”. OR=2.3 (0.8-6.1) • “Because you are African-American, you feel that you have to work twice as hard”. OR=1.9 (0.9--4.1)

  24. MATERNAL CHRONIC EXPOSURE TO INTERPERSONAL RACISM IN THE WORKPLACE AND INFANT BIRTH WEIGHT

  25. Self-Reported Experiences of Racial Discrimination and the Racial Disparity in Preterm Delivery: the CARDIA Study(Mustillo et al, AJPH, 2004)

  26. Racial Discrimination and the Racial Disparity in Low Birth Weight Delivery: the CARDIA Study (Mustillo et al, AJPH, 2004) • Unadjusted OR of LBW delivery for African-American (compared to White) women was 4.2 (1.3-13.7). • Adjusted (racial discrimination) OR of LBW delivery was 2.1 (0.8-5.9). • Adjusted (racism, SES, depression, alcohol, and tobacco use) OR of LBW delivery was 2.4 (0.8-7.4.

  28. Positive Income-Incongruity(Collins, Herman, David; AJPH, 1997) • Median family income of mother’s census tract residence is 1 S.D. above the mean income of non-Latino whites with same of years of parental education and marital status. • Proxy measure of societal advantages not captured by individual level variables; i.e. generational wealth.

  31. Disparities Weathering Bad Housing Unemployment Social policy Bad Neighborhoods Hopelessness Stress Poverty Limited Access to Care Adverse Environmental conditions Smoking Under- Education Family Support Poor Working Conditions Racism Lack of access to good Nutrition Adapted from A. R. James

  32. A 12-Point Plan: Lu and colleagues • 1.Provide interconception care to women with prior adverse pregnancy outcomes • 2. Increase access to preconception care for African American women • 3. Improve the quality of prenatal care • 4. Expand healthcare access over the life course • 5. Strengthen father involvement in African American families • 6. Enhance service coordination and systems integration • 7. Create reproductive social capital in African American communities • 8. Invest in community building and urban renewal • 9. Close the education gap • 10. Reduce poverty among African-Americans • 11. Support working mothers • 12. Undo racism: institutional, interpersonal
