OBJECTIVES: This paper examines the link between personnel and teacher smoking on school grounds, and student smoking in 62 low-income and middle-income countries. METHODS: We use a two-part model to estimate the effect of smoking by school personnel on youth smoking. In the first part, we model the decision to smoke for all students, using a linear probability model. In the second part, we estimate cigarette consumption among smokers. We employ country fixed effects to address... more
BACKGROUND: In a racially and ethnically diverse sample of recently diagnosed urban patients with breast cancer, we examined associations of patient, tumor biology, and mammography facility characteristics on the probability of symptomatic discovery of their breast cancer despite a recent prior screening mammogram. ... more
BACKGROUND: Racial/ethnic disparities exist along the breast cancer continuum, including time to a diagnosis. Previous research has largely focused on patient-level factors, and less is known about the role that health care facilities may play in delayed breast cancer care. OBJECTIVES: We examined racial/ethnic disparities in delayed diagnosis for breast cancer in the Breast Cancer Care... more
OBJECTIVES: We assessed public and smoker support for enacted and potential point-of-sale (POS) tobacco-control policies under the Family Smoking Prevention and Tobacco Control Act. METHODS: We surveyed a US nationally representative sample of 17 507 respondents (6595 smokers) in January through February 2013, and used linear regression to calculate weighted point estimates and... more
INTRODUCTION: Televised direct-to-consumer advertising (DTCA) for prescription drugs is controversial, especially for tobacco cessation products such as varenicline, given safety concerns that arose only after its market approval. We aim to quantify the extent to which DTCA influenced varenicline use. METHODS: We linked monthly... more
INTRODUCTION: Emerging evidence suggests bisexual populations are at increased risk for a variety of negative health outcomes, including tobacco use. Lesbian, gay, and bisexual (LGB) populations are at increased risk for cigarette smoking, but research on LGB subpopulations' use of tobacco products beyond cigarettes and tobacco use differences across LGB subgroups is in its infancy. This study explores differences... more
BACKGROUND: Deficits in decision-making and episodic memory are often reported among heavy cannabis users, yet little is known on how they influence negative consequences from cannabis use. Individual differences in decision-making may explain, in part, why some individuals experience significant problems from their cannabis use whereas others do not. We hypothesized that poor decision-making would... more

INTRODUCTION: This paper examined patterns in adults' sugar-sweetened beverage (SSB) consumption and caloric intake by Supplemental Nutrition Assistance Program (SNAP) participation status and by source of purchases in the United States (US). METHOD: Cross-sectional analysis of consumption of SSBs by source of purchases using 24-hour dietary recall data obtained from the US National Health and Nutrition Examination Survey 2003-2010 (N=17,891). Bivariate analysis and multivariable regressions were used to examine the association between... more
PURPOSE: Despite significant improvements in treatment for ovarian cancer, survival is poorer for non-Hispanic black (NHB) women compared to non-Hispanic white (NHW) women. Neighborhood socioeconomic status (SES) has been implicated in racial disparities across a variety of health outcomes and may similarly contribute to racial disparities in ovarian cancer survival. The purpose of this analysis is to... more
OBJECTIVES: We assessed sociodemographic disparities in local 100% smoke-free laws prohibiting smoking in all indoor areas of nonhospitality worksites, restaurants, and bars in 10 states. METHODS: We obtained data on local 100% smoke-free laws (US Tobacco Control Laws Database) and subcounty characteristics (2006-2010 American Community Survey) for Alabama, Alaska, Indiana, Kentucky, Mississippi, Missouri, North... more
