Introduction: Although California is home to the largest Hispanic/Latino population, few studies have compared smoking behavior trends of Hispanic/Latino nationality groups in California to the remaining United States (US), which may identify the impact of the state's anti-tobacco efforts on these groups. This study compared smoking status, freque...
Article
Introduction.: Prior to the Food and Drug Administration's (FDA) regulation of electronic cigarettes and warning statements related to nicotine addiction, there was no critical examination of manufacturer/distributor voluntary practices that could potentially inform FDA actions aimed to protect consumers.

This study compared cigarette consumption and former smoking trends in California (CA) with the rest of the United States (US) by racial/ethnic categories of non-Hispanic White, Black, Hispanic/Latino, and Asian/Pacific Islander groups. Data were analyzed from the 1992 to 2011 Tobacc...
Article
Background: The disproportionate burden of tobacco use among African Americans is largely unexplained. The unexplained disparities, referred to as the African American smoking paradox, includes several phenomena. Despite their social disadvantage, African American youth have lower smoking prevalence rates, initiate smoking at older ages, and during...

Existing data show that lung cancer disparities are not explained by cigarette smoking dose and duration alone. Data from the Multiethnic Cohort Study show that Native Hawaiians and African Americans who smoked 10 cigarettes per day have an elevated risk of lung cancer compared to Japanese American, White, and Latino smokers.

This randomized controlled study examines whether Family Foundations (FF)-a transition to parenthood program for couples focused...
Article
Menthol cigarette smoking may increase the risk for tobacco smoke exposure and inhibit nicotine metabolism in the liver. Nicotine metabolism is primarily mediated by the enzyme CYP2A6 and the nicotine metabolite ratio (NMR= trans 3'hydroxycotinine/cotinine) is a phenotypic proxy for CYP2A6 activity. No studies have examined differences in this biom...

We examined biomarkers of tobacco smoke exposure among Native Hawaiians, Filipinos, and Whites, groups that have different lung cancer risk. We collected survey data and height, weight, saliva, and carbon monoxide (CO) levels from a sample of daily smokers aged 18-35 (n = 179). Mean measures of nicotine, cotinine, cotinine/cigarettes per day ratio,...

LITS experience adverse health effects related to smoking. Previous research has aggregated Asian American ethnic groups, masking important differences between groups....
Article
Siblings play a significant but neglected role in family socialization dynamics, and focusing on the sibling relationship is a non-stigmatizing point of entry into the family for prevention programming. Siblings are Special (SAS) was designed as a universal program that targets both sibling relationship and parenting mediating processes in middle c...
Article

Smoking prevention interventions have been shown to be effective in reducing smoking prevalence in the United States. Further work is needed to address smoking in China, where over one third of the world's current smokers reside. China, with more than 60% of the male population being smokers, also presents a unique opportunity to test cognitive pro...
Article
Full-text available
School-based prevention programs are not common in China and the attempts to modify successful Western prevention programs have largely shown little effect. Distinct cultural and social systems differences could explain why modified programs have been unsuccessful. Smoking behavior is examined from the perspective of Chinese adolescents as part of...

BACKGROUND. For children and adolescents, obesity is the most prevalent nutrition-related disease in the United States. Currently, 17.1% of US children and adolescents are overweight and only 21.4% of youth meet the minimum recommendations of 5 servings of fruits and vegetables per day. Those who are overweight or obese are at higher risk for devel...
Conference Paper
This study examined whether own smoking behaviors, actual smoking behaviors of friends and depressive symptoms contributed to perceptions of friend smoking prevalence rates. Two hundred thirty-four adolescents (45% male, 41% of whom had ever tried smoking) participated in this study. Students completed a self-report survey on their smoking behavior...
Article
Tobacco control efforts are among Bulgaria's leading health priorities, although enforcement of policies translated from other regions is challenging due to the high national smoking prevalence, especially among health professionals and school personnel.
