The association of smoking with drinking pattern may provide opportunities to reduce smoking among students

There is evidence that smoking and alcohol consumption are paired behaviours among university students, but we know little about how New Zealand students engage in these behaviours. We estimated prevalence of daily and occasional smoking among university students, and associations of smoking with drinking patterns, demographics and smokefree policies of the university. This research was conducted with 2822 university students, aged 17–25, from five New Zealand universities who participated in an online health survey in 2013. Fourteen percent reported they currently smoke occasionally, and 3% reported smoking on a daily basis. Increasing age, living situation, drinking more often, and drinking more alcohol during drinking occasions were all associated with greater levels of smoking. Understanding patterns of smoking in relation to alcohol consumption may help efforts to further reduce smoking prevalence. Specifically, policy makers should consider approaches that de-couple tobacco and alcohol consumption, such as expanding the smokefree perimeter of bars and disallowing the sale of tobacco at premises licensed to sell alcohol.     

Absolute Risk or Relative Risk? A Study of Intraspecies and Interspecies Extrapolation of Chemical‐Induced Cancer Risk

We have used the CBDS database of the National Toxicology Program to study the difference between absolute risk and relative risk models for interspecies and intersex predictions of cancer risk. For no combination (class) of tumor and site is the prediction good for all chemicals. The variation in predicted risk between chemicals exceeds the difference in risks resulting from application of these two models. On the whole, it appears that relative risk is a better model.     

Racial and Ethnic Differences in the Timing of First Marriage and Smoking Cessation

Using data from the National Longitudinal Survey of Youth 1979 (N = 4,050), we consider the relationship between the timing of family formation and positive changes in health behavior. Theories that predict both positive and negative associations are tested. The findings suggest that both mechanisms operate and that the direction of the association depends on the respondent’s race or ethnicity. Whites who marry early are less likely to quit smoking, whereas Whites who marry on time and Blacks and Hispanics who marry at all ages are more likely to quit. The analysis refines the understanding of how family formation shapes changes in health behaviors differentially across the life course, and it underscores the difference in this process for individuals from different racial and ethnic backgrounds.

Evaluating Public Commentary and Scientific Evidence Submitted in the Development of a Risk Assessment

Risk assessments form the methodological basis for many public policies. A key component of the risk assessment process is the public commentary period. We conducted a case study of the California environmental tobacco smoke risk assessment to describe the contribution of the commentary to the risk assessment process. We used content analysis to examine the sources, quantity, and quality of public commentary, as well as the agency's response to the commentary. We examined the type and quality of publications cited in the commentary. Most of the comments were from critics of the risk assessment (36/44, 80%), especially tobacco industry affiliates (30/36, 83%). Critics were more likely to evoke the science evaluation criteria of study quality, reliability, and validity than were supporters. More than half the critics argued that appropriate procedures were not followed (13/23, 57%). Of the 29 commentaries on the respiratory, carcinogenic, and cardiovascular chapters, four resulted in changes to the risk assessment, such as the addition of new references or reanalysis of data. Journal articles were the most frequently cited type of reference, cited by critics (1,022/1,526 of references, 67%) and supporters (39/60, 65%). However, journal articles submitted by critics had lower impact factors than those cited by supporters (2.6 vs. 3.6, p=0.03). Participation in the public input process was not balanced among all interested parties, although this may reflect different opportunities for stakeholders to participate in stages of the process. Critics and supporters of the risk assessment used different criteria to evaluate the scientific evidence, suggesting that they were socially constructing the evidence to support their positions.     

Assessing College Students' Autonomy Over Smoking With the Hooked on Nicotine Checklist

Objective, Participants, and Methods: In this study, the authors explored the psychometric properties of the Hooked on Nicotine Checklist (HONC) among 300 college students who were current smokers. The HONC is a 10-item survey instrument designed to measure diminished autonomy over smoking, a key aspect of dependence. Autonomy is diminished when symptoms present a barrier to cessation. Results: Internal consistency was high (α = .89), as was concurrent validity. Students who began smoking earlier and heavier smokers reported more symptoms than did those who started later and smoked less. After controlling for smoking frequency, the HONC was predictive of the likelihood of a failed cessation attempt, with each additional symptom doubling that likelihood. Conclusions: College health professionals could use the HONC to help new smokers recognize their symptoms of diminished autonomy. The HONC may serve as a recruiting tool for cessation programs, which could benefit such early-phase smokers.     

Differences in Tobacco Use Among Two-Year and Four-Year College Students in Minnesota

Abstract

Objective: This study compares tobacco use rates among two-year and four-year college students and explores the demographic variables that predicted that behavior. Participants: 9,931 students at 14 two-year and four-year colleges in Minnesota participated. Methods: Students at 11 schools completed an online survey, and students at 3 schools completed a paper survey in 2007. Results: After controlling for sex, age, ethnicity, relationship status, hours of work per week, and number of school credits, attending a two-year college predicted current and daily smoking (odds ratio [OR]) = 1.70, 95% confidence interval [CI] = 1.52–1.89; OR = 3.47, 95% CI = 2.94–4.11) and smokeless tobacco use (OR = 1.65, 95% CI = 1.32–2.06; OR = 1.64, 95% CI = 1.06–2.53). Conclusions: Although two-year college students comprise approximately two fifths of the college student population, surveys of college student tobacco use have focused nearly exclusively on four-year college students. Two-year college students should represent a priority population for tobacco control because attending a two-year college predicts increased tobacco use.     

Thai Adolescents' Normative Beliefs of the Popularity of Smoking Among Peers,Adults, the Successful and Elite,and Parents

The purpose of this study was to assess the perceptions of Thailand adolescents regarding the prevalence of smoking, the popularity of smoking among successful/elite elements of society, and disapproval of smoking by friends and parents. These perceptions were analyzed in conjunction with actual smoking and smoking susceptibility rates among the subjects to determine whether beliefs and behaviors were associated with each other. This study was conducted among a school‐based sample of 2516 Chiang Mai, Thailand upper secondary and vocational students. Although perceived prevalence of smoking was not associated with smoking outcomes, perceived popularity of smoking among the successful and elite was associated with higher risk, and perceived disapproval by friends/parents was associated with lower risk. Youth smoking programs should consider assessing and taking these social normative factors into account when considering educational intervention strategies that aim to lower adolescent smoking rates.

Unhealthy behavior clustering and mental health status in United States college students

Abstract

Objective: Examine the association of health risk behavior clusters with mental health status among US college students. Participants: 105,781?US college students who completed the Spring 2011 National College Health Assessment. Methods: We utilized the latent class analysis to determine clustering of health risk behaviors (alcohol binge drinking, cigarette/marijuana use, insufficient physical activity, and fruit/vegetable consumption), and chi-square and ANOVA analyses to examine associations between the class membership and mental health (mental health diagnoses, psychological symptoms, and self-injurious thoughts/behaviors). Results: Three classes were identified with differing rates of binge drinking, substance use, and insufficient physical activity but similar rates of insufficient fruit/vegetable consumption. Students classified with the highest rates of binge drinking and cigarette/marijuana use had the highest rates across all mental health variables compared to other classes. Conclusions: Students who reported engaging in multiple health risk behaviors, especially high alcohol and cigarette/marijuana use, were also more likely to report poorer mental health.
