Poly-tobacco Use Among Youth and Adults in the United States

This dissertation 1) described prevalence and correlates of poly-tobacco use among US youth and young adults; 2) addressed positive and negative transitions of e-cigarettes among US youth and adults and 3) examined the 2-year transition of dual e-cigarette/cigarette use among US adults in relation to nicotine dependence (ND) symptoms, interest in quitting, and cardiovascular disease (CVD) factors. Data from 2013-2016 of the Population Assessment of Tobacco and Health Study were used. In the first study, 3.6% of youth (12-17years) and 18.3% of young adults (18-34years) were current poly-tobacco users between 2013-2014. Common poly-tobacco products combination was cigarettes and e-cigarettes for youth and young adults. Among youth, heavy drinking was associated with higher odds of poly-tobacco use. Factors associated with higher odds of poly-tobacco use among young adults included males, younger adults (18-24years), those with lower levels of educational attainment, residing in the South, heavy drinking, and marijuana use. In the second study, between 2013-2016, e-cigarette use increased only in youth. Young e-cigarette users were more likely to be never cigarette smokers compared to older users. Among youth e-cigarette users at each wave, the proportion of never cigarette smokers rose from 24.1% in Wave 1 to 42.6% in Wave 3 (p=0.0001 for trends). Among adult e-cigarette dual users in Wave 1, 8.8% transitioned to no tobacco use at Wave 3, 6.2% to mono e-cigarette use, while 85% either relapsed to cigarettes (53.5%) or continued dual use (31.5%). In the final study, among 1,870 adult dual tobacco users from Wave 1, 25·8% (95% CI 23·5-28·3) remained dual users 2 years later, 11·9% (95% CI 10·5-13·5) reported no tobacco use (cessation transition), 7·0% (95% CI 5·5-8·7) reported e-cigarette mono use (harm reduction transition), and 55·3% (95% CI 52·6-58·0) reported cigarette mono use (relapse transition). In the adjusted regression analysis, ND severity was associated with lower odds of cessation (OR 0·36; 95% CI 0·15-0·88) and harm reduction (OR 0·18; 95% CI 0·04-0·82) transitions. Interest in quitting and CVD factors were not associated with cessation or harm reduction. Collectively, our study findings emphasize the need for stricter tobacco regulatory policies to prevent another tobacco epidemic

Greater acculturation is associated with poorer cardiovascular health in the multi-ethnic study of atherosclerosis

BACKGROUND: Greater acculturation is associated with increased risk of cardiovascular disease. However, little is known about the association between acculturation and ideal cardiovascular health (CVH) as measured by the American Heart Association’s 7 CVH metrics. We investigated the association between acculturation and ideal CVH among a multi-ethnic cohort of US adults free of clinical cardiovascular disease at baseline. METHODS AND RESULTS: This was a cross-sectional analysis of 6506 men and women aged 45 to 84 years of 4 races/eth-nicities. We examined measures of acculturation(birthplace, language spoken at home, and years lived in the United States [foreign-born participants]) by CVH score. Scores of 0 to 8 indicate inadequate, 9 to 10 average and 11 to 14 optimal CVH. We used multivariable regression to examine associations between acculturation and CVH, adjusting for age, sex, race/ethnicity, education, income and health insurance. The mean (SD) age was 62 (10) years, 53% were women, 39% non-Hispanic White-, 26% non-Hispanic Black-, 12% Chinese-and 22% Hispanic-Americans. US-born participants had lower odds of optimal CVH (odds ratio [OR]: 0.63 [0.50– 0.79], P\u3c0.001) compared with foreign-born participants. Participants who spoke Chinese and other foreign languages at home had greater odds of optimal CVH compared with those who spoke English (1.91 [1.08– 3.36], P=0.03; and 1.65 [1.04– 2.63], P=0.03, respectively). Foreign-born participants who lived the longest in the United States had lower odds of optimal CVH (0.62 [0.43– 0.91], P=0.02). CONCLUSIONS: Greater US acculturation was associated with poorer CVH. This finding suggests that the promotion of ideal CVH should be encouraged among immigrant populations since more years lived in the United States was associated with poorer CVH

Cessation outcomes in adult dual users of e-cigarettes and cigarettes: the Population Assessment of Tobacco and Health cohort study, USA, 2013-2016.

OBJECTIVES: We examined the transitions of adult dual e-cigarette/cigarette users in the USA in relation to nicotine dependence (ND) symptoms, interest in quitting, and history of cardiovascular disease (CVD). METHODS: We used the Population Assessment of Tobacco and Health study Waves 1 and 3 (2013-2016) in a longitudinal analysis of adults (≥ 18 years). Dual past-month users of e-cigarettes/cigarettes were identified from Wave 1 and followed for tobacco use transitions 2 years later (Wave 3). RESULTS: Among 1870 adult dual users at Wave 1, 25.7% (95% CI 23.5-28.2) were dual users 2 years later, 12.1% (95% CI 10.6-13.7) reported no past-month tobacco use, 7.0% (95% CI 5.6-8.9) e-cigarette mono-use, and 55.2% (95% CI 52.4-58.0) cigarette mono-use. In the regression analysis, greater ND severity was associated with decreased relative risk of no past-month tobacco use (RRR 0.29; 95% CI 0.12-0.71). Interest in quitting and CVD factors were not associated with no past-month tobacco or e-cigarette mono-use. CONCLUSIONS: Dual users who are nicotine dependent are less likely to transition to cessation. To quit cigarette use, other cessation resources may be necessary to support the needs of cigarette smokers who use e-cigarettes, particularly those at risk of continuing cigarette smoking or those with smoking-related illnesses

Greater Acculturation is Associated With Poorer Cardiovascular Health in the Multi-Ethnic Study of Atherosclerosis

BACKGROUND: Greater acculturation is associated with increased risk of cardiovascular disease. However, little is known about the association between acculturation and ideal cardiovascular health (CVH) as measured by the American Heart Association's 7 CVH metrics. We investigated the association between acculturation and ideal CVH among a multi‐ethnic cohort of US adults free of clinical cardiovascular disease at baseline. METHODS AND RESULTS: This was a cross‐sectional analysis of 6506 men and women aged 45 to 84 years of 4 races/ethnicities. We examined measures of acculturation(birthplace, language spoken at home, and years lived in the United States [foreign‐born participants]) by CVH score. Scores of 0 to 8 indicate inadequate, 9 to 10 average and 11 to 14 optimal CVH. We used multivariable regression to examine associations between acculturation and CVH, adjusting for age, sex, race/ethnicity, education, income and health insurance. The mean (SD) age was 62 (10) years, 53% were women, 39% non‐Hispanic White‐, 26% non‐Hispanic Black‐, 12% Chinese‐ and 22% Hispanic‐Americans. US‐born participants had lower odds of optimal CVH (odds ratio [OR]: 0.63 [0.50–0.79], P<0.001) compared with foreign‐born participants. Participants who spoke Chinese and other foreign languages at home had greater odds of optimal CVH compared with those who spoke English (1.91 [1.08–3.36], P=0.03; and 1.65 [1.04–2.63], P=0.03, respectively). Foreign‐born participants who lived the longest in the United States had lower odds of optimal CVH (0.62 [0.43–0.91], P=0.02). CONCLUSIONS: Greater US acculturation was associated with poorer CVH. This finding suggests that the promotion of ideal CVH should be encouraged among immigrant populations since more years lived in the United States was associated with poorer CVH

Alcohol Type and Ideal Cardiovascular Health Among Adults of the Multi-Ethnic Study of Atherosclerosis

BACKGROUND: Light to moderate alcohol consumption is associated with favorable cardiovascular health (CVH). However, the association between alcohol type and ideal CVH has not been well-established. We examined the relationship between alcohol type and ideal CVH as measured by the American Heart Association’s seven CVH metrics. METHODS: We analyzed data from 6,389 men and women aged 45–84 years from a multi-ethnic cohort free of cardiovascular disease. Alcohol type (wine, beer and liquor) was categorized as never, former, 0 but drink other alcohol types, >0 but 2 drinks/day. A CVH score ranging from 0–14 points was created from the seven CVH metrics (Inadequate score, 0–8; average, 9–10; optimal, 11–14). We used multinomial logistic regression to examine the association between alcohol type and CVH, adjusting for age, sex, race/ethnicity, education, income, health insurance, field site and total calorie intake. RESULTS: The mean (SD) age of participants was 62 (10) years and 53% were women. Participants who consumed 1–2 drinks/day of wine had higher odds of optimal CVH scores compared to those who never drank wine [adjusted prevalence odds ratio (POR) 1.64 (1.12–2.40)]. In comparison to participants who never drank beer, those who consumed >2 drinks/day of beer had lower odds of optimal CVH scores [0.31 (0.14–0.69)]. Additionally, those who consumed >2 drinks/day of liquor had lower odds of optimal scores compared to those who never drank liquor [0.32 (0.16–0.65)]. CONCLUSION: Moderate consumption of wine was associated with favorable CVH. However, heavy consumption of beer or liquor was associated with poorer CVH

Waterpipe smoking: the pressing need for risk communication

Introduction: Waterpipe (WP) smoking is an important public health problem that is rapidly evolving globally. Much of WP spread among youth is perpetuated by a misperception of reduced harms compared to cigarettes. Increasing awareness about WP smoking harms through health warning labels (HWLs) represents a promising policy and regulatory strategy to curb WP smoking. Areas covered: Peer-reviewed publications indexed in PubMed and CINAHL were searched in March 2019. This review focuses on the current knowledge of WP smoking characteristics, its spread and patterns of use globally, and some of the major WP-related health effects. This knowledge is utilized to advance a promising policy and regulatory avenue to curb WP smoking by increasing awareness of its potential harms through HWLs. It also addresses product configuration and unique features that influence the adaptation of HWLs for WP smoking. Expert opinion: HWLs are effective in communicating smoking-related risks to WP smokers in a way that affects their smoking behavior and experience as well as interest in quitting. Although based on limited data, the WP device appears to be a promising location for HWLs as it offers prolonged contact with smokers and those surrounding them
