Cigar smoking in California: 1990-1996

Tobacco-product usage as a risk factor for dental implants

The oral cavities of tobacco smokers and users of smokeless tobacco products are exposed to high concentrations of nicotine. A limited number of animal studies have assessed the effect of nicotine on osseointegration. Results from experimental studies have reported a statistically significant decrease, at 4 weeks of follow-up, in bone-to-implant contact among rats exposed to nicotine compared with unexposed rats. Nicotine increases the production of inflammatory cytokines (such as interleukin-6 and tumor necrosis factor-alpha) by osteoblasts. Waterpipe, pipe, and cigarette smokers are at increased risk of developing oral cancer, periodontal disease, and alveolar bone loss. One explanation for this is that smokers (regardless of the type of tobacco product) are exposed to similar chemicals, such as nicotine, tar, oxidants, polyaromatic hydrocarbons, and carbon monoxide. Moreover, raised levels of proinflammatory cytokines have been identified in the gingival crevicular fluid of cigarette smokers with peri-implant diseases. Therefore, it is hypothesized that nicotine and chemicals in tobacco smoke induce a state of oxidative stress in peri-implant tissues (gingiva and alveolar bone), thereby increasing the likelihood of peri-implant disease development via an inflammatory response, which if left uncontrolled, will result in implant failure/loss. In this regard, tobacco smoking (including cigarettes, waterpipe, and pipe) is a significant risk factor for peri-implant diseases. The impact of vaping electronic cigarettes using nicotine-containing e-juices remains unknown. Habitual use of smokeless tobacco products is associated with oral inflammatory conditions, such as oral precancer, cancer, and periodontal disease. However, the effect of habitual use of smokeless tobacco products on the success and survival of dental implants remains undocumented.

Preference for flavoured cigar brands among youth, young adults and adults in the USA

BACKGROUND

While cigarette consumption in the USA continues to decline, cigar consumption has increased. Tobacco-trade publications suggest that flavoured cigars are driving the recent growth in cigar consumption. Limited survey data exist to explore flavoured cigar preferences among youth and adults.

METHODS

This study used the 2010-2011 National Survey on Drug Use and Health (NSDUH) and Nielsen market scanner data. The NSDUH sample consisted of 6678 past 30-day cigar smokers who reported smoking a usual brand of cigars. NSDUH contains a measure on usual cigar brand smoked and was merged with Nielsen data to estimate the per cent of each cigar brand's market share that is flavoured.

RESULTS

Multivariate analyses indicate that youth, young adults, females, blacks, cigarette smokers, blunt users and daily cigar smokers are significantly more likely to report a usual cigar brand that is flavoured. Preference for a usual brand that produces flavoured cigars decreases significantly with age.

CONCLUSIONS

This study finds recent growth in flavoured cigar consumption and preference among youth and young adults for cigar brands that are flavoured. These findings underscore the need to expand monitoring of product attributes as well as individual-level cigar use behaviours captured through population surveillance.

Non-cigarette tobacco products: what have we learnt and where are we headed?

A wide variety of non-cigarette forms of tobacco and nicotine exist, and their use varies regionally and globally. Smoked forms of tobacco such as cigars, bidis, kreteks and waterpipes have high popularity and are often perceived erroneously as less hazardous than cigarettes, when in fact their health burden is similar. Smokeless tobacco products vary widely around the world in form and the health hazards they present, with some clearly toxic forms (eg, in South Asia) and some forms with far fewer hazards (eg, in Sweden). Nicotine delivery systems not directly reliant on tobacco are also emerging (eg, electronic nicotine delivery systems). The presence of such products presents challenges and opportunities for public health. Future regulatory actions such as expansion of smoke-free environments, product health warnings and taxation may serve to increase or decrease the use of non-cigarette forms of tobacco. These regulations may also bring about changes in non-cigarette tobacco products themselves that could impact public health by affecting attractiveness and/or toxicity.

Characteristics of users of cigars, bidis, and kreteks and the relationship to cigarette use

BACKGROUND

In the 1990s, youth use of alternative tobacco products including cigars, bidis, and kreteks increased. This article discusses the prevalence of youth use of cigars, bidis, and kreteks, and characteristics of users.

METHODS

The Cigar Use Reasons Evaluation (CURE)-a questionnaire assessing alternative tobacco use and associated attitudes and behaviors-was administered to middle and high school students from 12 school districts across Massachusetts.

RESULTS

Males were more likely to use all forms of alternative tobacco and females more likely to smoke cigarettes. Hispanics were less likely to smoke kreteks or use smokeless tobacco. Urban students were more likely to smoke bidis or use smokeless tobacco than suburban or rural youth. Most smokeless and alternative tobacco users were lifetime cigarette smokers. There was, however, a significant group of cigar smokers, associated with higher parental education, who were not current cigarette smokers.

CONCLUSIONS

Use of alternative tobacco poses a risk to the success of tobacco control efforts. While many alternative tobacco users smoke cigarettes, some alternative tobacco users are current cigarette smokers. Cigar use thus constitutes a potential serious risk for youth who otherwise might not be exposed to tobacco.

[Respiratory symptoms and diagnosis of COPD in smokers of various types to tobacco. Results from the IBERPOC study]

BACKGROUND

The aim of this study was to investigate the sociodemographic characteristics, smoking habits, the prevalence of respiratory symptoms and chronic obstructive pulmonary disease (COPD) in four groups of smokers: of cigarettes (SCt), of cigars (SCigar), of both (SB), of cigars currently but of cigarettes in the past (SCigarExCt) and of cigarettes currently but of cigars in the past (SCtExCigar).

METHOD

A multicenter epidemiological study enrolling 4,035 subjects aged between 40 and 69 years. One thousand nine hundred sixty-three were non-smokers and 1,146 were current smokers. Among the smokers, 869 were SCt, 37 were SCigar, 97 were SB, 86 were SCigarExCt and 57 were SCtExCigar. We analyzed sociodemographic characteristics, smoking and the prevalence of respiratory symptoms and COPD.

RESULTS

Cigar smokers were usually men, of lower socioeconomic status (p < 0.001) and older than cigarette smokers (p < 0.001), but CO concentrations in expired air were lower in the SCigar group than in the SCt group (5 ppm vs 15.7; p < 0.001). Informants who believed their smoking was not detrimental to their health or to that of second-hand smokers made up 86.5% of the SCigar group and 79.1% of the SCigarExCt group. COPD was diagnosed in 13.2% of the SCt group, in 24.7% of the SB group, and in 12.8% of the SCigarExCt group, in comparison with 4% of the non-smokers (p < 0.001 for all comparisons).

CONCLUSIONS

SCigar are mainly older men with lower educational levels. Their concentrations of CO in expired air are low and they have little awareness of the health risks posed by their habit. SCigar who were once smokers of cigarettes have a higher prevalence of respiratory symptoms and COPD than non-smokers and the same prevalence of COPD as SCt.

Trends in cigar smoking and perceptions of health risks among Massachusetts adults

OBJECTIVE

To track trends in cigar smoking and assess perceptions of cigar related health risks among Massachusetts adults.

DESIGN

A random digit dial telephone survey conducted in 1993 and a subsequent monthly random digit dial survey conducted March 1995 to June 2000.

PARTICIPANTS

4733 adults who completed the 1993 survey and 14 868 adults who completed the monthly survey between 1995 and 2000.

MAIN OUTCOME MEASURES

Trends in current and experimental cigar use and perceptions of health risks.

RESULTS

Current cigar usage increased significantly among men aged 18-34 years between 1993 (5.8%) and 1997-98 (18.2%), but began to decrease in 1999-2000 (13.5%). Young men were much more likely than older men or women of any age to have experimented with cigars in the year before interview, but this trend appears to have decreased slightly since 1998. Young male cigar smokers were increasingly those who never smoked cigarettes. Former cigarette smokers were not smoking cigars in greater numbers. Cigar smokers were roughly three times as likely as those who do not smoke cigars to believe cigars are a safer alternative to cigarettes, and that perception did not appear to change much over time.

CONCLUSION

Cigar usage increased dramatically among young men in Massachusetts in conjunction with national increases in sales and marketing of cigars, but now appears to be decreasing.

Patterns of cigar use in California in 1999

BACKGROUND

Adult cigar use in California increased substantially between 1990 and 1996.

METHODS

Cigar smoking prevalence is from the 1990, 1996, and 1999 California Tobacco Surveys (CTS), large cross-sectional random-digit-dialed surveys designed to identify trends in tobacco use in the California population. Questions added to the 1999 CTS allowed a more detailed assessment of cigar smoking patterns.

RESULTS

Adult cigar use prevalence increased from 2.5% (95% confidence interval [CI], 2.2-2.8) in 1990 to 4.9% (95% CI=4.5-5.3) in 1996, and declined to 4.4% (95% CI=4.1-4.7) in 1999. Nearly the entire decrease was accounted for by less use in adults who had never been cigarette smokers. Among current cigar smokers in 1999, 43.3% (95% CI=37.8-48.8) had not smoked a cigar in the last month, just 16.2% (95% CI=7.9-24.5) of never cigarette smokers smoked three or more cigars in the past month, but 10.4% (95% CI=5.0-15.8) of former cigarette smokers-the group with the highest level of cigar consumption-reported daily use.

CONCLUSIONS

Cigar use may have peaked in California around 1996; in 1999, the intensity of use was generally at modest levels. California's bans on smoking in bars and restaurants may limit cigar smoking while drinking, so that the observed patterns may or may not reflect those in the rest of the United States.

Cigar, pipe, and cigarette smoking as risk factors for periodontal disease and tooth loss

BACKGROUND

Our purpose was to test the hypotheses that cigar and pipe smoking have significant associations with periodontal disease and cigar, pipe, and cigarette smoking is associated with tooth loss. We also investigated whether a history of smoking habits cessation may affect the risk of periodontal disease and tooth loss.

METHODS

A group of 705 individuals (21 to 92 years-old) who were among volunteer participants in the ongoing Baltimore Longitudinal Study of Aging were examined clinically to assess their periodontal status and tooth loss. A structured interview was used to assess the participants' smoking behaviors with regard to cigarettes, cigar, and pipe smoking status. For a given tobacco product, current smokers were defined as individuals who at the time of examination continued to smoke daily. Former heavy smokers were defined as individuals who have smoked daily for 10 or more years and who had quit smoking. Non-smokers included individuals with a previous history of smoking for less than 10 years or no history of smoking.

RESULTS

Cigarette and cigar/pipe smokers had a higher prevalence of moderate and severe periodontitis and higher prevalence and extent of attachment loss and gingival recession than non-smokers, suggesting poorer periodontal health in smokers. In addition, smokers had less gingival bleeding and higher number of missing teeth than non-smokers. Current cigarette smokers had the highest prevalence of moderate and severe periodontitis (25.7%) compared to former cigarette smokers (20.2%), and non-smokers (13.1%). The estimated prevalence of moderate and severe periodontitis in current or former cigar/pipe smokers was 17.6%. A similar pattern was seen for other periodontal measurements including the percentages of teeth with > or = 5 mm attachment loss and probing depth, > or = 3 mm gingival recession, and dental calculus. Current, former, and non- cigarette smokers had 5.1, 3.9, and 2.8 missing teeth, respectively. Cigar/pipe smokers had on average 4 missing teeth. Multiple regression analysis also showed that current tobacco smokers may have increased risks of having moderate and severe periodontitis than former smokers. However, smoking behaviors explained only small percentages (<5%) of the variances in the multivariate models.

CONCLUSION

The results suggest that cigar and pipe smoking may have similar adverse effects on periodontal health and tooth loss as cigarette smoking. Smoking cessation efforts should be considered as a means of improving periodontal health and reducing tooth loss in heavy smokers of cigarettes, cigars, and pipes with periodontal disease.

Association of adolescent cigar use with other high-risk behaviors

OBJECTIVES

To describe the association of cigar use with use of cigarettes, smokeless tobacco, and alcohol among adolescents; and to examine the association of self-esteem, physical activity, and use of tobacco promotional items with cigar use.

METHODS

A cross-sectional study of 7104 girls and 5499 boys 10 to 15 years of age in 1997. Data were collected from self-report questionnaires.

RESULTS

The prevalence of cigar use increased with age among both girls and boys. Among 11-year-olds, only 1% of girls and 3% of boys had used a cigar, whereas among 15-year-olds, 11% of girls and 25% of boys had used a cigar. Cigar users were much more likely than nonusers to have experimented with cigarettes (girls, odds ratio [OR]: 23.6; 95% confidence interval [CI]: 17.2-32.3; boys, OR: 21.3; 95% CI: 17.1-26.6), smokeless tobacco (girls, OR: 7.5; 95% CI: 4. 5-12.4; boys, OR: 13.0; 95% CI: 9.8-17.4), and alcohol (girls, OR: 6. 6; 95% CI: 4.8-9.1; boys, OR: 6.8; 95% CI: 5.3-8.8). There was a strong association between cigar use and binge drinking, especially among boys (girls, OR: 11.6; 95% CI: 7.9-16.9; boys, OR: 34.8; 95% CI: 19.4-62.3). Cigar users reported more hours of weekly physical activity than did nonusers. Additionally, cigar users were more likely to report high social self-esteem and to possess a tobacco promotional item.

CONCLUSIONS

Adolescents who use cigars are more likely to use other tobacco products and alcohol, to report high social self-esteem, and to possess tobacco promotional items. Health care professionals and teachers should include cigar use in discussions with adolescents addressing substance use.
