RESUMO
Understanding social conditions prior to intervention design can enhance tobacco control interventions. This paper describes formative research conducted in 2010 about tobacco use in eight economically disadvantaged Dominican Republic communities, four of which participated in a previous intervention study (2003-2008). A combined US-Dominican team used a rapid assessment process to collect qualitative social and cultural data on tobacco use, knowledge and attitudes; plus observations about social and policy factors, such as exposure to secondhand smoke (SHS), tobacco regulations, pregnancy, health care provider (HCP) practices and sustainability of the 2003-2008 intervention. This assessment found that tobacco use varied by age. While all ages typically used cigarettes, older adults used relatively more unprocessed tobacco, which is seen as less harmful and less addictive. Middle-aged smokers typically used commercial cigarettes, which are viewed as dangerous, addictive, expensive and offensive. Young adults reported avoiding smoking, but using relatively more smokeless tobacco. Smoking during pregnancy has reportedly decreased. SHS was viewed as harmful, although smoke-free homes were uncommon. HCPs discussed tobacco issues mostly for patients with tobacco-related conditions. Sustainability of the 2003-2008 intervention appeared to be linked to active Community Technology Centers with strong leadership, and community social capital. This information could be used to design better targeted interventions in these communities.

BACKGROUND: Despite well-established negative health consequences of smokeless tobacco use (STU), the number and variety of alternative non-combustible tobacco products on the market have increased tremendously over the last 10 years, as has the market share of these products relative to cigarettes. While STU among non-Hispanic white youth has decreased over the last 10 years, the prevalence has remained constant among Hispanic youth. Here we examine demographic, psychosocial, and genetic risk associated with STU among Mexican heritage youth. METHODS: Participants (50.5 % girls) reported on psychosocial risk factors in 2008-09 (n = 1,087, mean age = 14.3 years), and smokeless tobacco use in 2010-11 (mean age = 16.7 years). Participants provided a saliva sample that was genotyped for genes in the dopamine, serotonin and opioid pathways. RESULTS: Overall 62 (5.7 %) participants reported lifetime STU. We identified five single nucleotide polymorphisms that increased the risk for lifetime use. Specifically, rs2023902 on SERGEF (OR = 1.93; 95 % CI: 1.05-3.53), rs16941667 on ALDH2 (OR = 3.14; 95 % CI: 1.65-5.94), and rs17721739 on TPH1 (OR = 1.71; 95 % CI: 1.00-2.91) in the dopamine pathway, rs514912 on TRH-DE (OR = 1.84; 95 % CI: 1.25-2.71) in the serotonin pathway, and rs42451417 on the serotonin transporter gene, SLC6A4 (OR = 3.53; 95 % CI: 1.56-7.97). After controlling for genetic risk, being male (OR = 1.86; 95 % CI: 1.02-3.41), obesity status (OR = 2.22; 95 % CI: 1.21-4.09), and both higher levels of anxiety (OR = 1.04; 95 % CI: 1.01-1.08) and social disinhibition (OR = 1.26; 95 % CI: 1.07-1.48) were associated with increased use. High subjective social status (OR = 0.78; 95 % CI: 0.64-0.93) was protective against use, while higher parental education (OR = 2.01; 95 % CI: 1.03-3.93) was associated with increased use. CONCLUSIONS: These data suggest that use of genetic risk, along with psychosocial, demographic, and behavioral risk factors may increase our ability to identify youth at increased risk for STU, which in turn may improve our ability to effectively target prevention messages to Mexican heritage youth.

Tobacco use is the leading preventable cause of deaths worldwide. The MPOWER package, the six recommended policies of the World Health Organization (WHO) to reverse the tobacco epidemic, strongly recommends monitoring tobacco use trends. Because evidence indicates that smoking addiction often starts before the age of 18 years, there is a need to monitor tobacco use among youths. During 2011, a National Tobacco Control Law was enacted in Argentina that included implementation of 100% smoke-free environments, a comprehensive advertising ban (prohibiting advertising, promotion, and sponsorship of cigarettes or tobacco products through any media or communications outlets), pictorial health warnings, and a prohibition against the sale of tobacco products through any means to persons aged <18 years. To ascertain trends in tobacco use among youths in Argentina, the Argentina Ministry of Health and CDC analyzed data from the Global Youth Tobacco Survey (GYTS) for 2007 and 2012 (the next year that it was administered in Argentina). The findings indicated that the overall proportion of youths aged approximately 13-15 years who reported ever smoking a cigarette declined from 52.0% in 2007 to 41.9% in 2012 with significant decreases among both males and females. In 2012, 52.5% of youths in Argentina reported secondhand smoke (SHS) exposure in their homes and 47.5% in enclosed public places in the 7 days preceding the survey. Increased public education and tobacco control efforts will be important to discouraging tobacco use and decreasing SHS exposure among youths in Argentina.
