Tobacco use is a significant public health problem in both Western and Eastern countries. An emerging line of studies suggests that lesbians, gays, and bisexuals (LGBs) are at increased risk for tobacco use in both the US and China, especially during young adulthood. However, the distinctive, accumulative risk profiles of tobacco use across sexual minority subgroups, particularly as distinguished by sex, remain inadequately understood. Additionally, the increasingly prevalent use of alternative tobacco products (ATPs), such as little cigars and cigarillos (LCCs), e-cigarettes, and hookah, have further complicated our understanding of the at-risk populations for tobacco use. There is a lack of research that explores the distinctive patterns in the association of sexual orientation, sex, and tobacco products that may be driving the tobacco disparities among sexual minorities in both countries. To advance our knowledge base regarding tobacco-related disparities in this vulnerable population, this dissertation addresses three research aims:
Aim 1: To systematically review and meta-analyze the empirical evidence on the distinctive sexual orientation and sex patterns in tobacco use among sexual minority men and women in the US.
Aim 2: To examine the relationship of sex and sexual orientation to tobacco use among young adults in the US.
Aim 3: To examine the relationship between minority stress, depression, and tobacco use among Chinese gay men versus bisexual men.
This dissertation research was guided by Minority Stress Theory (Meyer, 2003), which acknowledges that the higher rates of tobacco use among sexual minority young adults were explained by their sexual minority status. This series of studies makes novel contributions to the existing literature by providing evidence on the distinctive profiles in LGB use of tobacco products, as well as by determining what subgroups are most at-risk for negative health behaviors and outcomes. Additionally, the information provided by this research helps health educators and researchers to better understand tobacco use in key populations cross-culturally and aid in the development of more tailored tobacco intervention programming in both US and China.
