Given the negative effects of a breast cancer diagnosis and its treatments on body weight and bone mass, we investigated the effects of a 6‐month randomized controlled aerobic exercise intervention vs. usual care on body composition in breast cancer survivors. Secondary aims were to examine the effects stratified by important prognostic and physiologic variables. Seventy‐five physically inactive postmenopausal breast cancer survivors were recruited through the Yale–New Haven Hospital Tumor Registry and randomly assigned to an exercise (n = 37) or usual care (n = 38) group. The exercise group participated in 150 min/week of supervised gym‐ and home‐based moderate‐intensity aerobic exercise. The usual care group was instructed to maintain their current physical activity level. Body composition was assessed at baseline and 6‐months through dual‐energy X‐ray absorptiometry (DXA) by one radiologist blinded to the intervention group of the participants. On an average, exercisers increased moderate‐intensity aerobic exercise by 129 min/week over and above baseline levels compared with 45 min/week among usual care participants (P < 0.001). Exercisers experienced decreases in percent body fat (P = 0.0022) and increases in lean mass (P = 0.047) compared with increases in body fat and decreases in lean mass in usual care participants. Bone mineral density (BMD) was also maintained among exercisers compared with a loss among usual care participants (P = 0.043). In summary, moderate‐intensity aerobic exercise, such as brisk walking, produces favorable changes in body composition that may improve breast cancer prognosis.

While inadequate follow-up of abnormal exams undermines the potential benefits of mammography screening for all women, the observed race difference in this study may have implications for the persistent race difference in breast cancer stage at diagnosis and survival. More research is needed to identify factors that contribute to poor follow-up among African-American women.

BACKGROUND: Promoting racial/ethnic diversity within the physician workforce is a national priority. However, the extent of racial/ethnic discrimination reported by physicians from diverse backgrounds in today's health-care workplace is unknown. OBJECTIVE:To determine the prevalence of physician experiences of perceived racial/ethnic discrimination at work and to explore physician views about race and discussions regarding race/ethnicity in the workplace. PARTICIPANTS: Practicing physicians (total n=529) from diverse racial/ethnic backgrounds in the United States. MEASUREMENTS AND MAIN RESULTS:We examined physicians' experience of racial/ethnic discrimination over their career course, their experience of discrimination in their current work setting, and their views about race/ethnicity and discrimination at work. The proportion of physicians who reported that they had experienced racial/ethnic discrimination "sometimes, often, or very often" during their medical career was substantial among non-majority physicians (71% of black physicians, 45% of Asian physicians, 63% of "other" race physicians, and 27% of Hispanic/Latino(a) physicians, compared with 7% of white physicians, all p< 0.05). Similarly, the proportion of non-majority physicians who reported that they experienced discrimination in their current work setting was substantial (59% of black, 39% of Asian, 35% of "other" race, 24% of Hispanic/Latino(a) physicians, and 21% of white physicians). Physician views about the role of race/ethnicity at work varied significantly by respondent race/ ethnicity.CONCLUSIONS: Many non-majority physicians report experiencing racial/ethnic discrimination in the workplace. Opportunities exist for health-care organizations and diverse physicians to work together to improve the climate of perceived discrimination where they work.KEY WORDS: discrimination; race and ethnicity; workforce; health-care workers.

As neighborhood context is increasingly recognized as an important predictor of health outcomes and health behaviors, this analysis sought to determine the relationship between neighborhood-level socioeconomic status (SES) and regular mammography screening behavior. One thousand four hundred fifty-one women ages 40 to 79 years who obtained an ''index'' screening mammogram at one of five urban hospitals in Connecticut between October 1996 and January 1998 were enrolled in this prospective study. The logistic regression analysis includes the 1,229 women [484 African-American (39%) and 745 White (61%)] who completed telephone interviews at baseline and followup (average 29.4 months later) and for whom the study outcome, nonadherence to age-specific mammography screening guidelines, was ascertained. Neighborhoodlevel SES was determined using 1990 census tract information. Neighborhood-level SES variables (quartiles) were associated with nonadherence for AfricanAmerican women [neighborhood-level education and composite socioeconomic position index (SEP Index)] and White women (neighborhood-level crowding and neighborhood-level assets). Using race-specific categorizations reflective of individual-level SES distributions, the SEP Index and neighborhood-level education were associated with nonadherence to mammography screening guidelines for African-American women (marginally significant for White women), independent of individual-level SES and other known predictors of mammography screening use [AfricanAmerican women: SEP Index odds ratio (OR), 3.55; 95% confidence interval (95% CI), 1.
