Understanding Tobacco Use Behaviors Among African Americans: Progress, Critical Gaps, and Opportunities.

INTRODUCTION: Although multiple factors likely influence the differences between African Americans (AAs) and whites in cardiovascular disease and lung cancer mortality rates, historical patterns of tobacco use, particularly cigarette smoking, are the major contributors. This issue of Nicotine & Tobacco Research presents original research, a review, and commentaries that will serve to advance our understanding of several relevant behavioral similarities and differences between AAs and whites. BEHAVIORAL ANALYSIS: Here, we illustrate how the diverging trends in cigarette smoking between AA and white high school seniors observed since the mid-1970s were influenced by patterns of ever use and current use among ever users. During 1977 to 2014, the percentage of current users among ever users was higher, but less variable, among whites than AAs. Among adults, trends in self-reported cigarette smoking among non-Hispanic AAs and non-Hispanic whites are available since 1978. The trends observed were likely due in part to the maturation of the high school senior cohorts from the 1970s and 1980s when AA smoking rates declined sharply relative to whites. Later age of initiation among AAs and less quitting among older AAs, relative to whites, also contribute. CONCLUSIONS: Further research on multiple topics, including the continuation of use among ever users, use of multiple combusted and noncombusted products, provision of cessation support services, influence of discrimination, and validity of self-report would expand the science base. Strategies to reduce the marketing and availability of menthol and other characterizing flavorings and to enrich environments would promote the public's health.

The African American Youth Smoking Experience: An Overview.

INTRODUCTION: Beginning in the late 1970s, a very sharp decline in cigarette smoking prevalence was observed among African American (AA) high school seniors compared with a more modest decline among whites. This historic decline resulted in a lower prevalence of cigarette smoking among AA youth that has persisted for several decades. METHODS: We synthesized information contained in the research literature and tobacco industry documents to provide an account of past influences on cigarette smoking behavior among AA youth to help understand the reasons for these historically lower rates of cigarette smoking. RESULTS: While a number of protective factors including cigarette price increases, religiosity, parental opposition, sports participation, body image, and negative attitudes towards cigarette smoking may have all played a role in maintaining lower rates of cigarette smoking among AA youth as compared to white youth, the efforts of the tobacco industry seem to have prevented the effectiveness of these factors from carrying over into adulthood. CONCLUSION: Continuing public health efforts that prevent cigarette smoking initiation and maintain lower cigarette smoking rates among AA youth throughout adulthood have the potential to help reduce the negative health consequences of smoking in this population. IMPLICATIONS: While AA youth continue to have a lower prevalence of cigarette smoking than white youth, they are still at risk of increasing their smoking behavior due to aggressive targeted marketing by the tobacco industry. Because AAs suffer disproportionately from tobacco-related disease, and have higher incidence and mortality rates from lung cancer, efforts to prevent smoking initiation and maintain lower cigarette smoking rates among AA youth have the potential to significantly lower lung cancer death rates among AA adults.

Guidelines on nicotine dose selection for in vivo research.

RATIONALE: This review provides insight for the judicious selection of nicotine dose ranges and routes of administration for in vivo studies. The literature is replete with reports in which a dosaging regimen chosen for a specific nicotine-mediated response was suboptimal for the species used. In many cases, such discrepancies could be attributed to the complex variables comprising species-specific in vivo responses to acute or chronic nicotine exposure. OBJECTIVES: This review capitalizes on the authors' collective decades of in vivo nicotine experimentation to clarify the issues and to identify the variables to be considered in choosing a dosaging regimen. Nicotine dose ranges tolerated by humans and their animal models provide guidelines for experiments intended to extrapolate to human tobacco exposure through cigarette smoking or nicotine replacement therapies. Just as important are the nicotine dosaging regimens used to provide a mechanistic framework for acquisition of drug-taking behavior, dependence, tolerance, or withdrawal in animal models. RESULTS: Seven species are addressed: humans, nonhuman primates, rats, mice, Drosophila, Caenorhabditis elegans, and zebrafish. After an overview on nicotine metabolism, each section focuses on an individual species, addressing issues related to genetic background, age, acute vs chronic exposure, route of administration, and behavioral responses. CONCLUSIONS: The selected examples of successful dosaging ranges are provided, while emphasizing the necessity of empirically determined dose-response relationships based on the precise parameters and conditions inherent to a specific hypothesis. This review provides a new, experimentally based compilation of species-specific dose selection for studies on the in vivo effects of nicotine.

Patient-appraised couple emotion management and disease management among Chinese American patients with type 2 diabetes.

Family context exerts a strong influence on disease management among patients with chronic disease, but it is not clear which aspects of family life are most influential. This study examined the linkages between patient-appraised couple emotion management (conflict resolution, expressiveness, and respect) and disease management (biological, morale/depression, quality of life, and behavioral) among a relatively understudied group, Chinese American patients with type 2 diabetes. Significant main effects were found between patient-appraised couple emotion management, especially conflict resolution, and the morale component of disease management, but not the biological or behavioral components; both diabetes-specific and general relationship qualities (marital satisfaction) were independently linked to disease management. Acculturation did not qualify the findings. Similarities among ethnic groups in family and disease management relationships may be more common than differences.

The African Americanization of menthol cigarette use in the United States.

Today, over 70% of African American smokers prefer menthol cigarettes, compared with 30% of White smokers. This unique social phenomenon was principally occasioned by the tobacco industry's masterful manipulation of the burgeoning Black, urban, segregated, consumer market in the 1960s. Through the use of television and other advertising media, coupled with culturally tailored images and messages, the tobacco industry "African Americanized" menthol cigarettes. The tobacco industry successfully positioned mentholated products, especially Kool, as young, hip, new, and healthy. During the time that menthols were gaining a large market share in the African American community, the tobacco industry donated funds to African American organizations hoping to blunt the attack on their products. Many of the findings in this article are drawn from the tobacco industry documents disclosed following the Master Settlement Agreement in 1998. After a short review of the origins and growth of menthols, this article examines some key social factors that, when considered together, led to disproportionate use of mentholated cigarettes by African Americans compared with other Americans. Unfortunately, the long-term impact of the industry's practice in this community may be partly responsible for the disproportionately high tobacco-related disease and mortality among African Americans generally and African American males particularly.
