The impact of social constraints on insomnia among African-American breast cancer survivors: The mediating role of fear of recurrence.

Objective: Insomnia is a significant concern among African-American breast cancer survivors (BCS). Social constraints (SC)-receiving unsupportive or critical responses when expressing trauma-related emotions-and fear of recurrence (FOR) have been associated with insomnia. We examined FOR as a mediator in the relationship between SC and insomnia in African-American BCS.

Factors Associated with Exercise Motivation among African-American Men.

Objective: The primary aims of this study were to: (1) characterize exercise stages of change among a sample of African-American men, (2) determine if exercise motivation was associated with self-reported exercise behavior, and (3) examine if groups of personal (i.e., age, BMI, income, educational attainment, and perceived health), psycho-social (i.

An Examination of Self-Rated Health Among African-American Men.

Self-rated health is a concept that has been linked to objective health outcomes but has not received much attention with regard to African-American men. The purpose of this study is to examine the relation of multiple factors (sociodemographic, health behaviors, personal health measures, and personality traits) with self-rated health in a sample of African-American men. The role personality plays in self-rated health in combination with other variables among African-American males has not thoroughly been explored.

History, prejudice, and the study of social inequities.

Integrating a historical perspective into studies of prejudicial attitudes facilitates the interpretation of paradoxical findings of the kind cited in the target article. History also encourages research to move beyond the study of prejudice and to consider institutional and structural forces that maintain social inequities. Multilevel approaches can study these factors in both field and laboratory studies.

Racial discrimination and breast cancer incidence in US Black women: the Black Women's Health Study.

Perceived discrimination may contribute to somatic disease. The association between perceived discrimination and breast cancer incidence was assessed in the Black Women's Health Study. In 1997, participants completed questions on perceived discrimination in two domains: "everyday" discrimination (e.

A study of genetic association with electrophysiological measures related to alcoholism: GAW14 data.

Recently, alcohol-related traits have been shown to have a genetic component. Here, we study the association of specific genetic measures in one of the three sets of electrophysiological measures in families with alcoholism distributed as part of the Genetic Analysis Workshop 14 data, the NTTH (non-target case of Visual Oddball experiment for 4 electrode placements) phenotypes: ntth1, ntth2, ntth3, and ntth4. We focused on the analysis of the 786 Affymetrix markers on chromosome 4.

Genes, age, and alcoholism: analysis of GAW14 data.

A genetic analysis of age of onset of alcoholism was performed on the Collaborative Study on the Genetics of Alcoholism data released for Genetic Analysis Workshop 14. Our study illustrates an application of the log-normal age of onset model in our software Genetic Epidemiology Models (GEMs). The phenotype ALDX1 of alcoholism was studied.

Physiological responses to racism and discrimination: an assessment of the evidence.

A growing body of research explores the impact of encounters with racism or discrimination on physiological activity. Investigators have collected these data in laboratories and in controlled clinical settings. Several but not all of the studies suggest that higher blood pressure levels are associated with the tendency not to recall or report occurrences identified as racist and discriminatory.
