Alcohol-related sexual harassment in the workplace: A between and within industry analysis.

INTRODUCTION: Sexual harassment as a political/legal issue was revitalised by the #MeToo movement in 2017. We estimate the prevalence and development of alcohol-related sexual harassment (ASH) across industries over the years 2015 to 2021, including potential changes from 2017, and assess differences in the risk of ASH according to industry- and individual-level characteristics. METHODS: Based on annual surveys (2015-2021) among employees in 21 Norwegian industries (observations N = 11,512, individuals N = 6353). Age range 20-69 years, 48% women. Associations between ASH and industry- and individual-level demographics, work autonomy, work-related drinking and intoxication were estimated in linear probability models RESULTS: ASH prevalence was 6% between 2015 and 2021 and varied between 4% and 13% across industries. Men showed a gradual increase in ASH from 2015 to 2021. The was no significant trend among women or a change after #MeToo. Industries with older employees, more women and frequent intoxication at work-related occasions had more ASH, while those with more highly educated employees had less. At the individual level, frequent work-related drinking occasions, tendency to get intoxicated at these occasions, being a woman and younger age were associated with more ASH. We found no individual- or industry-level association between work autonomy and ASH. DISCUSSION AND CONCLUSIONS: Annually, 6% of Norwegian employees experience alcohol-related sexual harassment in work-related settings. The risk of ASH is higher among employees who are young, female, frequently drink and drink to intoxication at work-related events, and that work in industries with older employees, more women, less formal education and frequent intoxication.

Vaping among Norwegians who smoke or formerly smoked: reasons, patterns of use, and smoking cessation activity.

BACKGROUND: The majority of Norwegians who use e-cigarettes are adults who have smoked. Little is known about vaping reasons and -patterns in this group. The aim of this paper was to study vaping prevalence, patterns, and motivations among adults who smoke. Furthermore, to investigate smoking intensity and smoking cessation behaviour differences between those who vape and those who do not. METHODS: This study was based on two separate Norwegian samples: People who had ever smoked, from 2017 (N = 2099), and people who currently smoked and recent quitters, from 2018/2019 (N = 1336). Measures of vape frequencies, vape motives, and smoking cessation behaviours were utilised in descriptive analyses of relationships between vaping and smoking behaviour. RESULTS: Less than 1 in 10 in the ever-smoked group, 1 in 5 of the currently smoked or recently quit group, were currently vaping. Ever trial rates for vaping were much higher at 1 in 3 in the ever-smoked group, and 1 in 2 in the currently smoked or recently quit group. Dual use with combustible cigarettes was common, but people who smoked tended to use e-cigarettes less frequently while those who formerly smoked tended to use them more frequently. Both quitting attempts and smoking intensity reduction were positively associated with vaping, and the most common reasons for e-cigarette use were reported to be desires to reduce harm, to stop smoking, or to reduce smoking intensity. CONCLUSION: The results indicate that Norwegians who smoke tend to see e-cigarettes as a tool to reduce or completely stop smoking. The predominance of use-motivations related to reducing harm points at the importance of conveying correct information about relative harmfulness of tobacco- and nicotine products.

Smoking cessation aids and strategies: a population-based survey of former and current smokers in Norway.

BACKGROUND: In Norway, tobacco consumption is equally divided between combustible (cigarettes) and non-combustible (snus) tobacco. In the process of quitting, people who smoke can choose between several smoking cessation aids and strategies based on what is available on the market or what are recommended as cessation aids. A quit attempt may be planned or unplanned and consist of a gradual decline in consumption or an abrupt quitting. This study explores smoking cessation aids and strategies used at the latest quit attempt among people who have ever smoked. How prevalent is the use of various cessation aids and strategies, and do they correlate with each other? Are there any differences in successful quits depending on the use of a specific cessation aid or strategy? METHOD: We used repeated cross-sectional representative surveys in Norway for 2017, 2018, 2019 and 2020. The analytic sample consists of people aged 20 years or older who have ever smoked daily, more precisely current daily smokers with at least one quit attempt (n = 476), and former daily smokers who quit in 2012 or later (n = 397). Participants answered questions on cessation aids and strategies used at their last quit attempt. Logistic regression analysis was used to estimate the associations between cessation aids and strategies and sociodemographic and smoking-related variables and successful quit attempts. RESULTS: Fifty-six percent of people who ever smoked daily reported any use of cessation aids, and nicotine replacement therapy (NRT), snus and e-cigarettes were the most commonly used cessation aids. Snus and web/mobile use was associated with successful quits, while NRT was associated with unsuccessful quit attempts. When exclusive use was separated from the combined use of several aids, only snus was associated with successful quits. CONCLUSION: Snus use was found to be a "stand-alone" cessation aid, and only weakly associated with the use of other cessation aids. Further investigation of cessation aid preferences is needed, especially among smokers with little or no contact with health services and/or for whom traditional cessation aids have no appeal.

Public support for further regulating smoking, snus and e-cigarettes in Norway, and its associations with risk perceptions and tobacco use.

BACKGROUND: Public support is an indication of the legitimacy of governmental tobacco interventions. Little is known about what it is that shapes the support for various tobacco policy measures. We examine whether there are differences in public support for new measures against smoking, snus, and e-cigarettes in Norway, and whether public support is associated with user status and perceptions of the products' harm potential. DATA AND METHODS: In December 2017, 4,002 people aged between 16 and 89 answered a web-based questionnaire. The sample was randomly drawn from Norstat's web panel, and pre-stratified by gender, age, region, and education in order to obtain an approximate country-representative sample. Respondents were asked to indicate their support for eight possible future measures to further restrict accessibility of tobacco (asked separately with regard to smoking tobacco, snus and e-cigarettes respectively), on a five-point scale from 1 = 'no support' to 5 = 'full support'. We utilized means and t-tests to address differences in support between measures. We then constructed sum scores to assess the total support for regulating each tobacco product and subjected these indexes to linear regression analyses, controlling for background variables. RESULTS: For six of the eight proposed measures, public opinion is less supportive of e-cigarette regulations than of similar regulations for snus and, especially, smoking tobacco. In all three regression models, significant associations with risk perception, user status and gender were maintained after multiple controls. The associations with risk perceptions were stronger for support of snus and e-cigarette regulation than for smoking tobacco. CONCLUSION: Overall, these findings illustrate the key role of risk perceptions in forming public opinions regarding tobacco-preventive regulations and underline the importance of information to ensure that population risk perceptions are accurate.

The role of alcohol use and cigarette smoking in sickness absence: Are there social inequalities?

BACKGROUND: While studies have found a social gradient in negative consequences of drinking and smoking, evidence is less clear for a gradient also in alcohol use and smoking's association with sickness absence. We investigate the association between alcohol use and cigarette smoking and general sickness absence, and examine the moderating role of socio-economic status for these associations when controlling for general health status. METHOD: Questions on alcohol use, measured by the Alcohol Use Disorders Identification Test (AUDIT-C), smoking, general health and sickness absence were included in annual national cross-sectional telephone surveys on alcohol, tobacco and drug use (2015-18) amongst Norwegian adults aged 16-79-years (average response rate=59%). The analytic sample comprised 4719 full- and part-time employees aged 25-79 years (46.7% were female, mean age=44.3 years). Individual-level data on education were obtained from national registries. RESULTS: In adjusted negative binomial regression analyses, current and former daily smoking were associated with a higher occurrence of sickness absence in groups with low educational attainment, but not in groups with high educational attainment. Alcohol use was negatively associated with sickness absence. While a significantly higher number of sickness days was reported by smokers in the low compared with the high education group, educational attainment did not moderate the alcohol use - sickness absence association. CONCLUSION: Daily smoking is associated with sickness absence. A negative social gradient was found in the smoking - absence association. Reduced daily smoking might give a reduction in sickness absence.

The Response of Smokers to Health Warnings on Packs in the United Kingdom and Norway Following the Introduction of Standardized Packaging.

INTRODUCTION: Standardized packaging was phased in between May 2016 and May 2017 in the United Kingdom and July 2017 and July 2018 in Norway. In both countries, the health warnings on packs prior to standardized packaging being implemented were from the former Tobacco Products Directive library of warnings (text warnings covering 43% of the pack front and pictorial warnings covering 53% of the pack reverse). The warnings on packs, postimplementation, were from the current Tobacco Products Directive library of warnings (novel pictorial warnings covering 65% of the pack front and reverse) for the United Kingdom but unchanged in Norway. AIMS AND METHODS: Longitudinal online surveys were conducted prior to standardized packaging (United Kingdom: April-May 2016; Norway: May-June 2017) and postimplementation (United Kingdom: September-November 2017 and May-July 2019; Norway: August-September 2018). We explored smokers' response to the on-pack warnings (salience, cognitive reactions, and behavioral reactions). RESULTS: In the United Kingdom, noticing warnings on packs, reading or looking closely at them, thinking about them, thinking about the health risks, avoidant behaviors, forgoing cigarettes, and being more likely to quit due to the warnings significantly increased from waves 1 to 2, and then decreased from waves 2 to 3, but remained higher than at wave 1. In Norway, noticing warnings, reading or looking closely at them, thinking about them, thinking about the health risks, and being more likely to quit due to the warnings significantly decreased from waves 1 to 2; avoidant behaviors and forgoing cigarettes remained unchanged. CONCLUSIONS: The inclusion of large novel pictorial warnings on standardized packs increases warning salience and effectiveness. IMPLICATIONS: Two longitudinal online surveys in the United Kingdom and Norway explored the impact of standardized packaging on warning salience and effectiveness. That warning salience and effectiveness only increased in the UK postimplementation, where standardized packaging was implemented alongside new larger pictorial warnings on the pack front and reverse, and not in Norway, where standardized packaging was introduced but older smaller text warnings (pack front) and pictorial warnings (pack reverse) were retained, highlights the importance of removing full branding and introducing stronger warnings simultaneously.

Association between snus use over time and smoking cessation in Norwegian smokers.

BACKGROUND AND AIMS: The effect of snus (Swedish moist snuff) use over time on smoking cessation has not been clearly established. This study aimed to assess whether there is an association between snus use over the life-span and smoking cessation in Norway. DESIGN AND SETTING: Yearly national cross-sectional surveys (2007-17) among Norwegian adults. PARTICIPANTS: A total of 5353 ever-daily smokers aged 16-79 years, 61.0% of whom (n = 3268) had quit daily smoking, and 16.9% (n = 903) were ever snus users. MEASUREMENTS: Retrospective data on smoking and snus use initiation and smoking cessation. Cox proportional hazard models were applied to estimate the association between time from initiation of snus use and quitting smoking. FINDINGS: There was a significant association between snus use and quitting smoking during the 5 first years after starting using snus (hazard ratio = 1.92, confidence interval = 1.62-2.26), but not thereafter. CONCLUSION: In Norway, snus use appears to be associated with a higher likelihood of quitting smoking within the first 5 years of initiation of this use.

Associations between emotional tobacco brand attachment and quitting plans among Norwegian smokers and snus users.

While most tobacco users want to quit using tobacco, only a small minority succeed in quitting. Affective attitudes might influence health-related intentions and behavior. Emotional attachment to tobacco brands is an aspect of such affective attitudes. The aim of this study is to investigate emotional attachment to the personal snus or cigarette pack, as well as associations with quitting plans, among snus users and smokers. A sample of 1,450 smokers and 1,423 snus users (16-83 years, mean age 41 years, 41% women) was recruited from a web panel and weighted according to national statistics on smoking and snus use. Positive package-related feelings loaded on a single component in principal component analysis. Multinomial adjusted regressions were performed for smokers and snus users, with quitting plans as the dependent variable (no quitting plan, plan to quit within 6 months, plan to quit later) and emotional attachment as an independent variable. Smokers and snus users often endorsed statements expressing positive feelings related to buying and using their choice of tobacco brand, with endorsements ranging from 17% to 73%. Adjusted multinomial regressions showed that emotional attachment was associated with lower likelihood of planning to quit smoking within the next 6 months (adjusted odds ratio [AOR] = 0.68, p < .001) and lower likelihood of planning to quit snus use within the next 6 months (AOR = 0.54, p < .001) or later (AOR = 0.81, p < .01). Emotional attachment to tobacco brands is negatively associated with quitting plans among smokers and snus users. Policies to reduce brand attachment might lead to increased quitting plans and potentially increased quit attempts. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The relative impact of smoking, alcohol use and drug use on general sickness absence among Norwegian employees.

BACKGROUND: It is well documented that tobacco, alcohol and drug use can be detrimental to health. However, little is known about the relative impact of these factors on sickness absence, and whether the association between use of these substances and sickness absence is different for women and men. The aim of this study was to examine the association between tobacco-, alcohol- and drug use, as well as polydrug use, and sickness absence among Norwegian employees. METHODS: During 2011-2014, 1911 employees in Norway completed a questionnaire about their tobacco, alcohol and drug use habits, their total number of sickness absences during the last 12 months, and the length (no. of days) of their last sick leave. Samples of oral fluid were analysed for illegal and medicinal drugs. RESULTS: Daily smoking and current use of medical drugs were significantly associated with sickness absence. Employees who were daily smokers also had an increased likelihood of having long and frequent sickness absence. Use of snus (Swedish moist snuff), binge drinking, current use of illegal drugs and polydrug use were not significantly associated with sickness absence. Women and young participants were more likely to report having had sickness absence the past 12 months. However, the associations between daily smoking and medical drug use and sickness absence, respectively, were only statistically significant for men. CONCLUSION: According to this study, daily smoking and use of medical drugs are the substance use habits most closely associated with sickness absence. Implications for future research are discussed.

15-year-old tobacco and alcohol abstainers in a drier generation: Characteristics and lifestyle factors in a Norwegian cross-sectional sample.

AIMS: Norwegian adolescents currently drink and smoke less on average than previous cohorts. Based on cross-sectional survey data, the individual and familial characteristics of 15-year-old non-users and users of alcohol and tobacco were compared to identify correlates to abstinence. METHODS: The survey was approved by the Norwegian Social Science Service. The sample consisted of 3107 adolescents from a 2011 school-based survey, of which 848 (27.3%) did not drink alcohol nor use tobacco. Associations with leisure time activities, risk perceptions, parenting style and social factors were analysed by logistic regression. RESULTS: Most of the non-drinkers were also non-users of tobacco. Abstainers (neither alcohol nor tobacco use) tended to have less unorganized and more hobby-related leisure time activities, higher risk perceptions for smoking, and monitoring or emotionally supportive parents. They more rarely reported close relationships with their best friend and were more likely to report lower occurrences of drinking and smoking among friends or siblings. CONCLUSIONS: Differences in perceived parenting styles and a lower degree of unorganized leisure in the abstainer group points to monitoring and closer emotional ties between parents and children as important factors in adolescent abstinence. An implication of these results is that promoting hobby-based activities might be a useful strategy for preventing alcohol and tobacco use in young people.

Adolescent perceptions of dissuasive sticks: a web survey among 16-20 year olds in Norway.

BACKGROUND: While increasingly stringent rules for cigarette pack design restrict the advertising potential of cigarette packs, the cigarette stick itself remains a potential medium for marketing. Common design features are filters, slim cigarettes and capsule cigarettes. Recent research indicates lower general appeal, more negative perceptions of taste, and greater harm for cigarettes designed to be unappealing (dissuasive sticks), and the aim for the current study was to investigate perceptions of dissuasive cigarette sticks among Norwegian adolescents, and learn about factors that might make cigarettes unappealing to them. METHODS: Two hundred eighty-one adolescents, 16-20 years old, smokers and non-smokers, assessed the appeal, taste, harmfulness, and which one they would most likely want to try, of 6 different cigarette sticks in a web survey. The cigarette sticks included two standard designs: cork and white filter sticks, and 4 dissuasive designs: green sticks, yellow sticks, and two white sticks with a health warning printed on the side. RESULTS: All dissuasive designs were perceived as less appealing, worse tasting, more harmful than the standard cork tip and white tip cigarettes. The dissuasive sticks were less often chosen as a cigarette one would want to try. The evaluations of designs were relatively similar across gender, smoking and snus use status, and smoking susceptibility. In multinomial regressions, perceptions of taste and harm differences were associated with perceived product trial. CONCLUSIONS: This study supports earlier findings, and suggest that the use of unpleasant colours and warnings printed directly on cigarette sticks could increase perceived harmfulness, reduce notions of good taste, and possibly reduce desires to experiment with cigarettes in adolescence.

Associations between snus use, body mass index and general health in a cross-sectional population-based sample of women.

BACKGROUND: In Norway, snus use among women has increased substantially over the last decade, particularly in younger age groups. Snus use is associated with increased morbidity among men, but few studies have addressed health consequences of snus use among women. AIM: To investigate the associations between body mass index (BMI) and female snus use, and between self-rated general health and female snus use. METHODS: A nationally representative net sample of 13,756 women in Norway, aged 18-45 years, participated in a survey on lifestyle and health. Ordinal logistic regression was applied to address associations between snus use and BMI/general health, adjusting for age and lifestyle factors. RESULTS: Compared to never users of snus, daily snus users had a lower likelihood of high BMI (OR: 0.83, 95% CI: 0.68-1.00), a higher likelihood of low BMI (OR: 1.63, 95% CI: 1.14-2.33), and a higher likelihood of poor/fair health (OR: 1.43, 95% CI: 1.08-1.90). Former and occasional snus users did not differ from never users in terms of BMI or general health in multiply adjusted models. Daily smokers had the highest likelihood of reporting poor/fair health (OR: 2.18, 95% CI: 1.8-2.63) relative to never smokers. CONCLUSIONS: Daily female snus use was associated with a lower likelihood of being overweight, and a higher likelihood of being underweight. Moreover, daily snus use was associated with a higher likelihood of worse general health. Former and occasional female snus use was not associated with BMI or general health.

Cute as candy: a qualitative study of perceptions of snus branding and package design among youth in Norway.

OBJECTIVES: Snus use has increased among youth in Norway in recent years and is now more prevalent than smoking. Concurrently, a range of new products and package designs have been introduced to the market. The aim of this study was to explore how youth perceive snus branding and package design, and the role, if any, of snus packaging on perceptions of appeal and harm of snus among youth. PARTICIPANTS: Adolescent tobacco users and non-users (N=35) ages 15-17 years. DESIGN: We conducted interviews among 6 focus groups (each with 4-7 participants). Participants were shown snus packages with a variety of designs and with different product qualities (flavour additives, slim, regular, white and brown sachets) and group discussions focused on how they perceived packages and products. The focus group discussions were semistructured using a standard guide, and analysed thematically. RESULTS: The participants in the focus groups narrated distinct images of snus brands and associated user identities. Package design elements such as shapes, colours, images and fonts were described as guiding these perceptions. Packaging elements and flavour additives were associated with perceptions of product harm. The appeal of flavoured snus products and new types of snus sachets seemed to blend in with these processes, reinforcing positive attitudes and contributing to the creation of particular identities for products and their users. CONCLUSIONS: The findings indicate that packaging is vital to consumer's identification with, and differentiation between, snus brands. In view of this, snus branding and packaging can be seen as fulfilling a similar promotional role as advertising messages: generating preferences and appeal.

Adolescent tobacco use practices and user profiles in a mature Swedish moist snuff (snus) market: Results from a school-based cross-sectional study.

AIMS: The aim of this work was to study the diversity of tobacco use among Norwegian adolescent tobacco users and to investigate how different user groups compared with each other in terms of lifestyle and risk correlates. Swedish moist snuff (snus) use has increased dramatically in Norway over the last few years and is now more prevalent than smoking in younger age groups. METHODS: The participants were 736 15-year-old tobacco users obtained from a large school-based cross-sectional survey (response rate 73%). Leisure time activity and risk behaviour factors were extracted by principal components analysis. Associations between tobacco use, leisure activities, risk behaviours, alcohol use and sex were studied bivariately and by logistic regression. RESULTS: In total, 41.5% of the tobacco users were dual users (smokers and snus users). Problem behaviour and risk-taking lifestyles were associated with tobacco use frequency and high-frequency dual use, with a low risk profile for all types of occasional users (snus, cigarettes or dual users), a medium risk profile for all types of daily single-product users, including those who occasionally used the other product (i.e. dual users) and a high-risk profile for those who used both products daily (daily dual users). CONCLUSIONS: Fragmented use patterns in adolescence undermine the dichotomy often applied between smokers and snus users. For associations with lifestyle and risk correlates, use frequency and high-frequency dual use seem to be more important than the choice of product.

Lifestyle Correlates of Female Snus Use and Smoking: A Large Population-Based Survey of Women in Norway.

INTRODUCTION: While smoking in Norway has become less prevalent, snus use has increased, including among women. The aims of this study were to describe female snus use and its correlates, and to contrast patterns of snus use and smoking. METHODS: In 2011-2012, data on tobacco use, age, education, alcohol consumption, sexual behaviors, and physical activity were collected from a population based sample of 13 756 Norwegian women aged 18-45 years, using a self-administered questionnaire. RESULTS: Ever-use prevalence of snus ranged from 29.6% to 4.5% among those aged 18-19 years and 40-45 years, respectively. In contrast, the corresponding figures for smoking were 24.1% and 44.1%. Among snus users, 54.1% and 22.8% of 18-19 and 40 to 45-year-olds had never smoked, respectively. Debut age for snus use increased markedly with age, and was higher than debut age for smoking. Female snus use was positively associated with intermediate education, alcohol consumption, number of sexual partners, and hard physical activity. Smoking was also positively associated with alcohol consumption and number of sexual partners, but negatively associated with physical activity and education. CONCLUSION: While most snus users among older women were former or current smokers, this was not the case among younger women. Low snus debut age and extensive snus use among younger women suggest that measures to reduce snus use should be targeted at young adolescents. The correlates of female snus use and smoking were not identical, and were similar to those previously documented for men.

How has the availability of snus influenced cigarette smoking in Norway?

BACKGROUND: In Norway, low-nitrosamine smokeless tobacco (snus) is allowed to compete with cigarettes for market share. We aimed to study how the availability of snus influenced overall tobacco consumption, smoking initiation and smoking cessation. We discuss whether the Norwegian experience with snus can have any transfer value for e-cigarettes. METHODS: We analysed consumption data from registered and unregistered supply sources of tobacco. We calculated quit-smoking ratios across snus use status in nine datasets comprising a total of 19,269 ever-smokers. Trends in snus use and smoking were derived from time-series of annual; cross-sectional; nationally representative surveys for the period 1985-2013. RESULTS: The market share for snus increased from 4% in 1985 to 28% in 2012, but overall tobacco consumption decreased by 20.3% over this same period. Snus was the most common method for smoking cessation. Compared with smokers with no experience of using snus, the quit ratio for smoking was significantly higher for daily snus users in seven of the nine datasets analysed. Among young male adults, the prevalence of smoking (daily + occasional) was reduced from 50% in 1985 to 21% in 2013. Over the same period, use of snus increased from 9% to 33%. This negative correlation (r = -0.900, p < 0.001) was also observed among young females (r = -0.811, p < 0.001), but the trend shift in tobacco preferences occurred some years later. CONCLUSIONS: The experience with snus in Norway might indicate what will happen when alternative nicotine products--are allowed to compete with cigarettes in the nicotine market.

Lifetime smoking habits among Norwegian men and women born between 1890 and 1994: a cohort analysis using cross-sectional data.

OBJECTIVES: Providing lifetime smoking prevalence data and gender-specific cigarette consumption data for use in epidemiological studies of tobacco-induced cancer in Norway. Characterising smoking patterns in birth cohorts is essential for evaluating the impact of tobacco control interventions and predicting smoking-related mortality. SETTING: Norway. PARTICIPANTS: Previously analysed annual surveys of smoking habits from 1954 to 1992, and individual lifetime smoking histories collected in 1965 from a sample of people born in 1893-1927, were supplemented with new annual surveys of smoking habits from 1993 to 2013. Age range 15-74 years. PRIMARY OUTCOME MEASURE: Current smoking proportions in 5-year gender-and-birth cohorts of people born between 1890 and 1994. RESULTS: The proportion of smokers increased in male cohorts until the 1950s, when the highest proportion of male smokers (76-78%) was observed among those born in 1915-1934. Among women, the peak (52%) occurred 20 years later, in women born in 1940-1949. After 1970 smoking has declined in all cohorts of men and women. In the 1890-1894 cohorts, male smoking prevalence was several times higher than female, but the gap declined until no gender difference was present among those born after 1950. Gender-specific per capita consumption was even more skewed, and men have consumed over 70% of all cigarettes since 1930. The incidence of lung cancer for men peaked at around 2000, with the highest incidence rate estimated at ca. 38%. The incidence of lung cancer for women is still increasing, and estimated incidence rate for 2011 was 25.2%. CONCLUSIONS: In an epidemiological perspective, men have had a longer and more intense exposure to cigarettes than women. The gender-specific incidence of lung cancer reflects the gender difference in consumption over time.

Smoking and snus use onset: exploring the influence of snus debut age on the risk for smoking uptake with cross-sectional survey data.

INTRODUCTION: Snus use has become increasingly prevalent among young people in Norway, while smoking has declined. Little is known about the transitions between snus and other tobacco products, particularly among younger users. A major concern involves the association between snus initiation and future smoking uptake. METHODS: A total of 409 lifetime snus users who had started with snus before cigarettes or were never-smokers were selected from a national sample of participants in annually repeated cross-sectional surveys (2005-2011) of Norwegian men and women aged 15-74 years. About 30% of them were lifetime smokers, 84% were men, and the mean age was 29.4 years. Logistic regression was applied to investigate the association between age of snus uptake and the risk for becoming a smoker later on. RESULTS: Respondents who started using snus before the age of 16 years had an odds ratio of 3.1 (confidence interval = 1.98-4.76) of being lifetime smokers compared with those who initiated snus later. The prevalence of current smoking among early snus initiators (22.9%) was comparable to that found among never-snus-users (29.6%). Among late snus initiators, current smoking prevalence was 5.9%. CONCLUSION: In this study, snus debut age was an important factor for the association between snus use and smoking.

Perceptions of relative risk of disease and addiction from cigarettes and snus.

The public is largely unaware of the lower global risk associated with snus compared with that of cigarettes, but little is known of perceptions of relative risks for specific diseases. Inveterate, daily, and nondaily smokers' perceptions of the relative snus/cigarette risk of cardiovascular disease, and of cancer of the lung, stomach, and oral cavity, and perceptions among smokers, snus users, and dual users of the relative risk of nicotine addiction, was studied in a pooled sample from annual national surveys (2008-2011) performed by Statistics Norway. The total sample included 2,661 ever smokers and snus users aged 15-79 years old. Fifty-three percent were men, and the average age was 46.1 year. Compared with medical consensus, all smoker groups overestimated the relative risks of diseases from snus use, and inveterate smokers overestimated them significantly more than other groups. For all diseases except lung cancer, the majority of smokers thought snus users were running a higher or equal risk. For lung cancer, 22% believed that snus use gave a higher or equal risk. Smokers, snus users, and dual users tended to think that snus and cigarettes were equally addictive products, while a somewhat higher proportion of those who had quit both products thought that cigarettes were more addictive. Increased knowledge of the relative health risks might give smokers an incitement to switch to snus and prompt current dual users to stop smoking completely. Awareness could be improved by tailoring information at targeted groups, for example via the health care system.
