Racial ideology and explanations for health inequalities among middle-class whites.

Middle-class whites' explanations for racial inequalities in health can have a profound impact on the type of questions addressed in epidemiology and public health research. These explanations also constitute a subset of white racial ideology (i.e., racism) that in itself powerfully affects the health of non-whites. This study begins to examine the nature of attributions for racial inequalities in health among university students who by definition are likely to be involved in the research, policy, and service professions (the upper middle class). Investigation of the degree to which middle-class whites attribute racial inequalities in cardiovascular health (between themselves and African Americans, American Indians, or Asian Americans) to biological, social, or lifestyle factors reveals that whites tend to attribute their own health to lifestyle choice and to biology rather than to social factors. These results suggest that contemporary middle-class whites' "self-serving" explanations for racial inequalities in health are comprised of two beliefs: implicit biologism (race is an attribute of organisms rather than a social relation) and liberal belief in self-determination, choice, and individual responsibility--some of the core lay beliefs of the worldview that sustains neoliberal capitalism. Contemporary white middle-class explanations for racial inequalities in health appear to include assumptions that justify class inequality. Liberal approaches to racism in public health are bound to miss a key component of racial ideology that is currently used to justify racial and class inequalities.

Racial/ethnic differences in attitudes toward seeking professional mental health services.

OBJECTIVES: This study examined racial/ethnic differences in attitudes toward seeking mental health services. METHODS: Data from the National Comorbidity Survey, which administered a structured diagnostic interview to a representative sample of the US population (N = 8098), were analyzed. Multiple logistic regression was used, and data were stratified by need for mental health services. RESULTS: African Americans with depression were more likely than Whites with depression to "definitely go" (odds ratio [OR] = 1.8, P < .001) seek mental health services. African Americans with severe psychiatric disorders were less likely to be "somewhat embarrassed if friends knew they sought care" (OR = 0.3, P < .001) than were their White counterparts. CONCLUSIONS: African Americans reported more positive attitudes toward seeking mental health services than did Whites.

Racial differences in attitudes toward professional mental health care and in the use of services.

Differences in attitudes toward seeking professional mental health care and in the utilization of mental health services were examined by analyzing the second part of the National Comorbidity Survey. Prior to use of services, African Americans were found to have more positive attitudes than whites toward seeking such services, but less likely to use them. After utilization, their attitudes were found to be less positive than those of whites.

Social class, assets, organizational control and the prevalence of common groups of psychiatric disorders.

This study provides an update on the association between social class and common types of psychiatric disorder in the US. In addition to usual measures of social class, we provide hypotheses for the expectation that assets and organizational control are associated with specific varieties of psychiatric disorders (mood, anxiety, alcohol and drug use disorders). We analyzed two surveys. The National Comorbidity Survey conducted in 1990-1992 yielded 12-month prevalence rates in a probability sample of 8098 respondents in the 48 contiguous states. The Epidemiologic Catchment Area Follow-up conducted in 1993-1996 provided similar rates among 1920 East Baltimore residents. Analyses of the National Comorbidity Survey showed an inverse association between financial and physical assets and mood, anxiety, alcohol, and drug disorders. The Epidemiologic Catchment Area Followup provided additional evidence for the inverse association between financial and physical assets and anxiety, alcohol and drug disorders. Also in the Epidemiologic Catchment Area, lower level supervisors presented higher rates of depression and anxiety disorders than higher level managers. Inequalities in assets and organizational control, as well as typical measures of social class, are associated with specific psychiatric disorders. These constructs can provide additional explanations for why social inequalities in psychiatric disorders occur.

Vital status in the National Panel Survey of Black Americans: a test of the National Death Index among African Americans.

To test the specificity of the National Death Index (NDI), information was submitted on 157 randomly selected respondents from the National Panel Survey of Black Americans (NPSBA) who were known to be living as of 1992. Information also was submitted for 153 known deceased respondents from the panel survey to test the sensitivity of the NDI. The NDI was very sensitive; however, specificity was somewhat less impressive. Although we found the NDI/NPSBA match to be highly accurate, there was a nontrivial number of false positives.

Dirofilaria immitis: biochemical and immunological characterization of the surface antigens from adult parasites.

The molecules associated with the surface of adult Dirofilaria immitis were identified and characterized employing IODO-GEN-mediated surface labeling methods. D. immitis female and male parasites were found to have a limited number of surface-associated proteins (17.5, 16, and 14.5 kDa) and glycoproteins (49 and 20 kDa) which were readily extracted from parasite homogenates in the absence of detergent. The major surface labeled proteins and glycoproteins were antigenic in rabbits, but appeared to elicit only a weak humoral response in dogs with patent dirofilariasis. In addition, a 10- to 6-kDa surface-associated glycolipid was identified which may form a coat on the outside of the parasite and play a role in immune evasion. In immunoprecipitation experiments, the glycolipid was not recognized by the antibodies from rabbits exposed to the glycolipid or by antibodies in the sera of patently infected animals. The glycolipid and the 14.5-kDa surface protein were selectively released by the adult parasite during in vitro culture.
