  • Racism is a unique stressor that African
    Americans have had to experience. This type of
    stress may help to explain the disparities that
    exist in weight between African-American women
    and their racial/ethnic counterparts (Mays,
    Cochran Barnes, 2007).
  • Coping with stress has been associated with
    maladaptive health behaviors such as overeating,
    emotional eating, smoking, and physical
    inactivity that contribute to obesity (Torres
    Nowson, 2007 Sims et al, 2008 Steptoe, Wardle,
    Pollard, Canaan, Davies, 1996).
  • Although health behaviors were not assessed in
    this current study, literature suggests an
    association between coping with stress and
    behaviors that lead to overweight and obese
    conditions. In this particular sample of
    African-American women, maladaptive health
    behaviors may have been used to manage perceived
    racism, which may help explain increased BMI.
  • Approximately 80 of African-American women are
    overweight or obese (American Heart Association,
    2006).
  • Psychological stress has been linked to obesity
    (Dallman, 2009). Perceived racism is a type of
    stress unique to African Americans that has
    received little attention in the literature as it
    pertains to health outcomes (Clark, Anderson,
    Clark, Williams, 1999).
  • Perceived racism is associated with weight gain
    (Cozier, Wise, Palmer Rosenberg, 2009).
  • Hostility has also been associated with behaviors
    that lead to obese and overweight conditions such
    as physical inactivity and increased caloric
    intake (Allen, Markovitz, Jacobs Knox, 2001).

Purpose The purpose of this research is to
further extend the current knowledge on obesity
in African-American women to include coping with
perceived racism and hostility. More
specifically, the goal is to establish whether
coping with perceived racism and hostility
predict obesity. Hypotheses We hypothesized
that coping with perceived racism and hostility
will be positively correlated with obesity. In
addition, we hypothesized coping with perceived
racism and hostility will also be independent
predictors of BMI.
  • These findings indicate that coping with
    perceived racism is critical for a thorough
    assessment of obesity risk in African- American
    women.
  • Health professionals should assess for
    psychological stressors that are relevant to the
    African-American experience.
  • Weight loss interventions should incorporate
    stress management techniques that strengthen
    psychological resources available to help
    African-American women cope with unique stressors
    in their lives such as perceived racism.

Design and Methodology
  • Participants The participants were a community
    based sample of African-American women, 18 to 73
    years of age, who resided in the Washington, DC
    Metropolitan Area.
  • Setting The study site was Howard University
    Hospitals
  • General Clinical Research Center (GCRC) located
    in
  • Washington, DC.
  • Tests and Measures Participants were
    administered the Perceived Racism Scale (McNeilly
    et al., 1996) and Cook Medley Hostility (Ho)
    Scale (Cook Medley, 1954). Participants also
    underwent a medical examination, which included
    weight and height measurements that were used to
    calculate BMI.
  • Data Analysis Partial and bivariate correlations
    and hierarchical regression analyses were
    utilized. BMI was square root transformed to
    correct for skewness.
  • This research is part of a larger study entitled
    Stress and Psychoneuroimmunological Factors in
    Renal Health and Disease that is funded by The
    National Center on Minority Health and Health
    Disparities under grant 1P20MD000512-04, A
    Research Center to Reduce Ethnic Disparities in
    ESRD.

  • Coping with perceived racism and hostility were
    correlated with BMI.
  • After adjusting for age, income, and years of
    education, only the relationship between coping
    with perceived racism persisted.
  • Coping with perceived racism predicted higher BMI
    after adjusting for age, income, and years of
    education.
