The relationship of smoking cessation to sociodemographic characteristics, smoking intensity, and tobacco control policies.

The present study examined the relationship between recent smoking cessation activities and sociodemographic characteristics, smoking intensity, and tobacco control policies among daily smokers in the United States. The study used the U.S. Current Population Survey 1998-1999 Tobacco Use Supplement, supplemented with information on state-level tobacco control policies. The sample was limited to individuals aged 25 years or older who were smoking daily 1 year ago. We estimated frequencies and multivariate logistic equations for making a quit attempt and remaining abstinent at least 3 months. These measures were related to demographic characteristics, smoking intensity, and tobacco control policies. Younger, higher socioeconomic status (SES), and less intense (fewer cigarettes per day) daily smokers were more likely to make quit attempts, but the likelihood of remaining abstinent for those making a quit attempt was greater for older, higher SES, and heavy daily smokers. We found evidence that cessation behaviors were related to higher cigarette prices and the presence of state-level media/comprehensive campaigns, but less clear evidence exists for an association with bans restricting workplace smoking. The results indicate that certain types of smokers are more likely to attempt to quit and to have success and that the characteristics of these smokers differ. Price policies can have an important role in helping daily smokers to quit. Further research is needed regarding the role of quantity smoked.     

The role of psychiatric disorders in the relationship between cigarette smoking and DSM-IV nicotine dependence among young adults.

This study set out to evaluate the association between cigarette smoking and nicotine dependence (Diagnostic and Statistical Manual of Mental Disorders [4th ed.]) (DSM-IV), and to determine whether psychiatric disorders may signal greater sensitivity to nicotine dependence at similar levels of smoking exposure. Drawing on the young adult sample (aged 18-25 years) from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), we conducted logistic regression analyses. Smokers with major depression, alcohol use disorders, or specific phobia had a higher risk of meeting DSM-IV criteria for nicotine dependence than did those without these disorders. When examining smoking quantity, we found that rates of nicotine dependence were similar for those with and without major depression among nondaily smokers, yet among daily smokers, rates of nicotine dependence were consistently higher among those with major depression than among those without. Alcohol dependence elevated the risk of nicotine dependence at low to moderate levels of use. However, no difference in risk for nicotine dependence was observed between alcohol-dependent and nondependent individuals smoking more than a pack a day. Increased risk of nicotine dependence among those with a specific phobia was consistent across the range of current smoking levels. These findings add to the growing literature documenting dependence in nondaily smokers and demonstrate that although chronic smoking is often a key feature in dependence, psychiatric disorders may signal greater sensitivity to nicotine dependence symptoms at substantially lower levels of smoking exposure.     

Cigarettes, alcohol, and depression: characterizing head and neck cancer survivors in two systems of care.

Tobacco exposure is a key risk factor for head and neck cancer, and continued smoking after diagnosis negatively affects outcomes. The present study examined tobacco smoking, nicotine dependence, alcohol use, and depression in survivors of head and neck cancer. Subjects at least 6 months post-initial diagnosis of head and neck cancer (N=694) drawn from three VA otolaryngology clinics (n=309, VA patients) and a university-based otolaryngology clinic (n=385, non-VA patients) were administered questionnaires and standardized rating instruments for nicotine and alcohol dependence and for depression. Additional clinical information was extracted from chart reviews. Despite high rates of prior smoking, less than one-quarter of all subjects continued to smoke. After controlling for significant confounding variables, we found that VA patients were more likely to be current smokers (OR=1.9, 95% CI=1.3-3.0), but current VA smokers did not differ significantly from non-VA smokers on the Fagerstr?m Test for Nicotine Dependence criterion (p=.69). The VA patients were more likely to screen positive for problem drinking on the Alcohol Use Disorder Identification Test (OR=2.1, 95% CI=1.3-3.7). After adjusting for other variables, we found no statistical difference between the groups in depression scores on the Geriatric Depression Scale-Short Form. The study provides data on smoking, alcohol use, and depression in head and neck cancer survivors indicating that VA patients are at increased risk for continued smoking and problem drinking relative to non-VA patients. Head and neck cancer patients benefit from aggressive smoking cessation efforts by the VA, but many patients need specialized services that integrate smoking interventions with treatment of comorbid alcoholism.     

The relationship between cigarette use, nicotine dependence, and craving in laboratory volunteers.

Data from epidemiological studies suggest that individual differences in cigarettes per day (CPD) and duration of smoking account for only a small portion of the variance in Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) nicotine dependence. However, DSM-IV may be an insensitive measure of nicotine dependence; other measures might better reflect the true nature of the relationship between use and dependence. This paper describes the relationship between cigarettes per day (CPD) and years smoking and the severity of nicotine dependence as measured by the Nicotine Dependence Syndrome Scale (NDSS). Furthermore, we assessed the validity of individual differences in nicotine dependence by determining whether they related to cue-evoked craving during abstinence. Data were pooled from five laboratory studies of 489 regular (i.e., 15+ CPD) smokers. In contrast to previously reported data demonstrating a relatively strong relationship between CPD and dependence in chippers (Shiffman & Sayette, 2005), CPD and years smoking accounted for a statistically significant, but small (<6%), portion of the variance in nicotine dependence in daily smokers. Individual differences in both CPD and years smoking had little or no relationship with craving. However, the magnitude of craving was significantly related to the degree of nicotine dependence even after controlling for use variables and excluding craving-related items on the NDSS. These data suggest that among moderate to heavy daily smokers, meaningful individual differences in nicotine dependence are observed independent of differences in current daily cigarette consumption and duration of smoking. Further research into the sources of this variance is critical to understanding the process of and risk for nicotine dependence.     

Support for spirituality in smoking cessation: results of pilot survey.

Patient spiritual resources are increasingly included in the treatment of medical conditions such as cancers and alcohol and drug dependence, but use of spiritual resources is usually excluded from tobacco dependence treatment. We hypothesized that this omission may be linked to perceived resistance from smokers. To examine this hypothesis, we conducted a pilot survey to assess whether current smokers would consider spiritual, including religious, resources helpful if they were planning to quit. Smokers at least 18 years of age at Oregon Health & Science University in Portland, Oregon, (N=104) completed a brief survey of smoking behaviors and spiritual beliefs. None were attempting to quit. Of these individuals, 92 (88%) reported some history of spiritual resources (spiritual practice or belief in a Higher Power), and of those respondents, 78% reported that using spiritual resources to quit could be helpful, and 77% reported being open to having their providers encourage use of spiritual resources when quitting. Results of logistic regression analysis indicated that those aged 31-50 years (OR=3.3), those over age 50 years (OR=5.4), and women (OR=3.4) were significantly more likely to have used spiritual resources in the past. Of the 92 smokers with any history of spiritual resources, those smoking more than 15 cigarettes/day were significantly more receptive to provider encouragement of spiritual resources in a quit attempt (OR=5.4). Our data are consistent with overall beliefs in the United States about spirituality and recent trends to include spirituality in health care. We conclude that smokers, especially heavier smokers, may be receptive to using spiritual resources in a quit attempt and that spirituality in tobacco dependence treatment warrants additional investigation and program development.     

Empirically derived latent classes of tobacco dependence syndromes observed in recent-onset tobacco smokers: epidemiological evidence from a national probability sample survey.

This study pursued a line of large-sample epidemiological research on tobacco dependence syndromes that may appear during the first 2 years of tobacco smoking, as clinical features begin to emerge. Focusing on smokers who just recently started using tobacco may provide insights into the transitions that lead from initial smoking toward tobacco dependence. A specific focus was a possible excess risk of tobacco dependence associated with early-onset smoking. Data came from public use files of the 1995-1998 National Household Surveys on Drug Abuse. Analyses were based on responses from 2,993 smokers, that is, those whose age at onset of tobacco smoking was either equal to the age at the time of the interview (n=1,030) or within 1 year of the age at the interview (n=1,963). Seven clinical features were assessed for a measure of the tobacco dependence syndrome, elicited during a standardized assessment. Findings from latent class analysis best support a model with three classes of smokers; features of tobacco dependence are prominent in just two of these classes, which in aggregate constitute 29% of the recent-onset smokers. Earlier-onset tobacco smokers may have a modestly higher probability of expressing dependence features within 2 years of smoking onset, compared with later-onset smokers (i.e., those starting after age 20). Clinical features of tobacco dependence emerge within 1-2 years after the onset of smoking. If the three-class model of tobacco dependence is correct, early-onset smoking may confer modest excess risk of becoming tobacco dependent during the first 2 years after smoking onset.     

Nicotine dependence versus smoking prevalence: comparisons among countries and categories of smokers

OBJECTIVES: To collect available international data on nicotine dependence as defined by the Fagerstrom Test of Nicotine Dependence, and to compare levels of dependence among countries and categories of smokers. DATA SOURCES: Published and unpublished studies known to the authors and a search of EMBASE from 1985-1995. STUDY SELECTION: Studies included were those based on a nationally representative sample of a country's population, or a sample of smokers seeking cessation assistance. DATA SYNTHESIS: Smokers who seek help in stopping smoking are much more dependent than the average smoker. Men consistently score higher on dependence than women. Ex-smokers appear to have lower dependence than current smokers. A country with low smoking prevalence, the United States, seems to have smokers with higher dependence scores than countries where smoking is more prevalent (such as Austria and Poland). CONCLUSIONS: Successful tobacco control may result in a higher dependence among the remaining smokers (due to selective quitting by low-dependent smokers). The remaining highly dependent smokers may need more intensive treatment.


     

Sex-related differences in serum cotinine concentrations in daily cigarette smokers

Self-reported use of cigarettes generally underestimates the true cigarette exposure of smokers. Serum cotinine is considered the best biomarker to evaluate tobacco exposure. This study determined whether or not there were any significant differences in serum cotinine concentrations between men and women when they reported smoking the same number of cigarettes per day. We analyzed cotinine and tobacco consumption data on 680 women and 840 men, aged 20 years or older, who smoked at least 100 cigarettes during their lifetime and were still actively smoking at the time of the National Health and Nutrition Examination Surveys (1999-2002). Overall, compared with men, women reported smoking fewer cigarettes per day (16.1 vs. 18.7, p<.001) and had lower serum cotinine concentrations (1163.3 nmol/L vs. 1343.9 nmol/L, p<.001). Women were more likely than men to smoke filtered (p = .018) and mentholated (p<.001) cigarettes. After adjustment for the number of cigarettes smoked per day, age, race, body mass index, poverty status, the use of either menthol or regular cigarettes, and the nicotine content in cigarettes, female compared with male smokers had lower serum cotinine concentrations (difference of 117.6 nmol/L; 95% CI = 42.6-192.6, p = .003). The difference was particularly notable in moderate to heavy smokers (i.e., those who smoked more than 15 cigarettes/day). These findings indicate that significant sex-related differences exist in serum cotinine levels among smokers, which suggests that self-reports may overestimate cigarette exposure in women compared with men.     

Cigarette smoking and smoking cessation among older adults: United States, 1965-94

OBJECTIVE: To characterise patterns of cigarette smoking and smoking cessation among older adults in the United States. DESIGN: Data from the National Health Interview Surveys (NHIS) 1965-94 were analysed. The NHIS is a cross-sectional survey using a representative national sample. SETTING: In most cases interviews were conducted in the home; telephone interviews were conducted when respondents could not be interviewed in person. PARTICIPANTS: Participants were from a representative sample of the American civilian, non-institutionalised population aged 18 and older. Sample sizes for the years analysed ranged from n = 19,738 to n = 138,988 overall, and n = 3806 to n = 12,491 for those aged 65 years and older. MAIN OUTCOME MEASURES: Using the NHIS data from 1965-94, trends in current smoking and the prevalence of smoking cessation by demographic characteristics among older adults (65 years and older) were assessed and compared with trends among younger adults. A logistic regression analysis was conducted to determine the demographic characteristics of former smokers compared with current smokers among those aged 65 and older. RESULTS: The prevalence of current smoking among 65 year olds and older declined from 1965 to 1994 (17.9% to 12.0%). Although smoking prevalence was lower among older adults than younger adults (aged 18- 64), the rate of decline in smoking was slower among older adults. Among older adults, the prevalence of cessation rose with increasing educational attainment, and was consistently higher for men than for women and for whites compared with blacks. After adjustment for demographic factors among older adults who had ever smoked, increasing age and educational attainment were strongly related to the likelihood of being a former smoker. Although there were no racial differences among women, older white (OR = 2.6) and Hispanic (OR = 3.67) men were significantly more likely to be former smokers than older black men. Also, the gender difference in smoking cessation was noted only for whites. CONCLUSIONS: Given the projected increase in the elderly population, the medical and economic consequences of smoking will become a greater burden in the next decades. Therefore, focusing attention on cessation among the elderly is an immediate and urgent priority for public health professionals and clinicians.


     

Favourite movie stars, their tobacco use in contemporary movies, and its association with adolescent smoking

OBJECTIVE: To assess the relation between adolescents' favourite movie stars, the portrayal of tobacco use by those stars in contemporary motion pictures, and adolescent smoking. DESIGN AND SETTING: 632 students (sixth to 12th grade, ages 10-19 years) from five rural New England public schools completed a voluntary, self administered survey in October 1996. The survey assessed tobacco use, other variables associated with adolescent smoking, and favourite movie star. In addition, tobacco use by 43 selected movie stars was measured in films between 1994 and 1996. OUTCOME MEASURES: Students were categorised into an ordinal five point index (tobacco status) based on their smoking behaviour and their smoking susceptibility: non-susceptible never smokers, susceptible never smokers, non-current experimenters, current experimenters, and smokers. We determined the adjusted cumulative odds of having advanced smoking status based on the amount of on-screen tobacco use by their favourite film star. RESULTS: Of the 43 stars, 65% used tobacco at least once, and 42% portrayed smoking as an essential character trait in one or more films. Stars who smoked more than twice in a film were considered smokers. For adolescents whose favourite stars smoked in only one film, the odds of being higher on the smoking index was 0.78 (95% confidence interval (CI) 0.53 to 1.15). For adolescents whose favourite stars smoked in two films, the odds of being higher on the smoking index was 1.5 (95% CI 1.01 to 2.32). For adolescents whose favourite stars smoked in three or more films (Leonardo DiCaprio, Sharon Stone, John Travolta), the odds of being higher on the smoking index was 3.1 (95% CI 1.34 to 7.12). Among never smokers (n = 281), those who chose stars who were smokers in three or more films were much more likely to have favourable attitudes toward smoking (adjusted odds ratio 16.2, 95% CI 2.3 to 112). CONCLUSIONS: Adolescents who choose movie stars who use tobacco on-screen are significantly more likely to have an advanced smoking status and more favourable attitudes toward smoking than adolescents who choose non-smoking stars. This finding supports the proposition that the portrayal of tobacco use in contemporary motion pictures, particularly by stars who are admired by adolescents, contributes to adolescent smoking.     

Tobacco spending and children in low income households

OBJECTIVE: To examine the role of tobacco use in creating financial hardship for New Zealand (NZ) low income households with children. DATA: The 1996 NZ census (smoking prevalence by household types), Statistics NZ (household spending surveys 1988-98), and NZ Customs (tobacco released from bond 1988-98). MAIN OUTCOME MEASURES: Proportion of children in households with smokers and < or = 15,000 NZ dollars gross income per adult. Proportion of spending on tobacco of second lowest equivalised household disposable income decile and of solo parent households. RESULTS: In < or = 15,000 NZ dollars gross income per adult households with both children and smokers, there were over 90,000 children, or 11% of the total population aged less than 15 years. Enabling second lowest income decile households with smokers to be smoker-free would on average allow an estimated 14% of the non-housing budgets of those households to be reallocated. CONCLUSIONS: The children in low income households with smokers need to be protected from the financial hardship caused by tobacco use. This protection could take the form of more comprehensive government support for such households and stronger tobacco control programmes. A reliance on tobacco price policy alone to deter smokers is likely to have mixed outcomes-for example, increased hardship among some of these households. The challenge for tobacco control is to move from a sole focus on "doing good" towards incorporating the principle of "doing no harm".     

Gender effects of reported in utero tobacco exposure on smoking initiation, progression and nicotine dependence in adult offspring.

We examined the relationship between self-reported in utero tobacco exposure and gender on smoking initiation, progression of cigarette use (i.e., telescoping), and current levels of nicotine dependence in adult treatment-seeking smokers. Subjects (N = 298) who reported "yes" (28% of the original sample) or "no" (50% of the original sample) to in utero tobacco exposure were included in the analyses. Telescoping was calculated as the difference between the age respondents smoked their "first full cigarette" and the age when they started smoking daily. Females who reported being exposed in utero transitioned from initial to daily cigarette use more rapidly than females not exposed. The opposite effect was found for males, which may be related to our finding that in utero exposure lowered the age of cigarette experimentation in exposed compared with unexposed males. Measures of current cigarette use and dependence (i.e., Fagerstr?m Test for Nicotine Dependence, prior withdrawal, number of past year quit attempts) were significantly associated with reported in utero exposure, gender, or interactions of exposure and gender. In utero tobacco exposure may accelerate the progression from experimentation to daily use in girls, result in early tobacco experimentation among boys, and produce higher levels of nicotine dependence among adult smokers.     

Characteristics of selectors of nicotine replacement therapy

Objective: To assess differences in demographic and smoking characteristics between smokers who have and have not used nicotine replacement therapy (NRT). Design: Mail survey of US smokers from a national research panel. Participants: Smokers 18 years and over who returned a survey on smoking (n = 9630). The sample was weighted to match the US smoker population on age and sex. Main outcome measures: Compared smokers who had/had not used NRT in a quit attempt (ever NRT use or over the counter (OTC) NRT use) on: demographic characteristics, nicotine dependence, history of craving and withdrawal, expected difficulty quitting, and self reported history of smoking related medical illness and psychopathology. Results: NRT users (both ever-users and OTC users) were more likely to be older, male, and better educated. They were also heavier smokers, had experienced more craving and withdrawal upon quitting, and scored higher on measures of dependence. These differences were evident among light smokers, and remained even when smoking rate and time to first cigarette were controlled. Conclusion: Smokers who elect to use NRT differ from non-NRT users in ways that predispose them to failure in cessation. Controlling for smoking rate and time to first cigarette does not eliminate these differences, even among light smokers. These differences must be considered when comparing the effectiveness of NRT among samples of smokers who self select their treatment and are likely to bias such outcome comparisons.     

Psychosocial, behavioural, and health determinants of successful smoking cessation: a longitudinal study of Danish adults

OBJECTIVE—To examine the factors that determine whether or not smokers become long-term quitters, and to study whether determinants of successful cessation differ with levels of motivation to stop.
DESIGN—In a cohort of men and women, aged 30-60 years at first examination in 1982/1984, smoking behaviour was evaluated from questionnaires at baseline and at follow up 10 years later.
SETTING—County of Copenhagen, Denmark
PARTICIPANTS—2554 subjects from the original sample of 4581 were successfully followed. This study deals with the 1365 subjects who were smokers at the first examination.
MAIN OUTCOME MEASURE—Smoking status (abstinent for one year or more) at follow up.
RESULTS—At follow up 15% of the baseline smokers had been abstinent for one year or more. In multivariate analysis, successful smoking cessation was associated with older age, high social status, low prior tobacco consumption, baseline motivation to stop smoking, and having a non-smoking spouse/cohabitant. The same result was obtained when the analyses were repeated separately for smokers with and without motivation to stop.
CONCLUSIONS—Smokers motivated to stop are more likely to quit and remain abstinent than smokers with no such motivation. Age, social status, spouse/cohabitant's smoking behaviour, and the daily consumption of tobacco predict success in smoking cessation, irrespective of smokers' former motivation to stop.

Smoking prevalence and risk factors for smoking in a population of United States Air Force basic trainees

OBJECTIVE—To provide a comprehensive assessment of smoking prevalence and risks for smoking in an entire population of United States Air Force (USAF) military basic trainees (n = 32 144).
DESIGN—Population-based survey with every individual entering the USAF enlisted force from August 1995 to August 1996.
SETTING—USAF Basic Military Training (BMT) facility at Lackland Air Force Base, Texas. All trainees were assessed during the first week of BMT.
MAIN OUTCOME MEASURES—A 53-item questionnaire was developed to assess four domains: demographics, smoking history, risk factors for smoking, and other health behaviours.
RESULTS—Approximately 32% of the trainees smoked regularly before basic training and a small percentage of the trainees (7.6%) described themselves as ex-smokers. Men, Euro-Americans, and those from lower educational backgrounds were more likely to smoke than other trainees. On average, smokers had smoked for approximately four years and had low nicotine dependence scores. Individuals who had smoked before BMT were more likely to use other drugs (such as alcohol, binge drinking, smokeless tobacco), and were less physically active than never-smokers. These findings were particularly strong for those who smoked up to basic training but were also evident for ex-smokers.
CONCLUSIONS—Smoking is a prevalent risk factor among individuals entering the USAF. Furthermore, smoking was related to other risk factors believed to lower military readiness, including alcohol use and decreased physical activity. Comprehensive tobacco control policies aimed at reducing smoking among military trainees are needed.

Smoking behaviour and attitudes among adult Saudi nationals in Riyadh City, Saudi Arabia

OBJECTIVE: To measure the smoking behaviour and attitudes among Saudi adults residing in Riyadh City, the capital of the Kingdom of Saudi Arabia. DESIGN: Cross-sectional survey. SETTING AND SUBJECTS: Primary health care centres (PHCCs) in Riyadh City were selected by stratified random sampling. Subjects resident in each PHCC catchment area were selected by systematic sampling from their records in the PHCCs; 1534 adults aged 15 years and older were interviewed during January to April 1994. MAIN OUTCOME MEASURES: Self-reported smoking prevalence; age of smoking initiation; daily cigarette consumption; duration of smoking; reasons for smoking, not smoking, and quitting smoking; intentions to smoke in the future; and attitudes toward various tobacco control measures. RESULTS: 25.3% of respondents were current smokers, 10.2% were ex-smokers, and 64.5% had never smoked. About 79% of all smokers started smoking between the ages of 15 and 30 years, and 19.5% before age 15. Significantly higher smoking prevalence and daily cigarette consumption were associated with being male, single, and being more highly educated. Relief of psychological tension, boredom, and imitating others were the most important reasons for smoking, whereas health and religious considerations were the most important reasons for not smoking among never-smokers, for quitting among ex-smokers, and for attempting to quit or thinking about quitting among current smokers. About 90% of all subjects thought that they would not smoke in the future. Physicians and religious men were identified as the most effective anti-smoking advocates by a much higher proportion of respondents (44%) than nurses, health educators, and teachers (each less than 5%). Health and religious education were generally cited as more effective in deterring smoking than tobacco control laws and policies. CONCLUSIONS: Cigarette smoking is prevalent among Saudi adults in Riyadh, particularly males, most of whom begin to smoke rather early in life and continue for many years. Health and religious education should be the cornerstone for any organised tobacco control activities, which are urgently needed to combat the expected future epidemic of smoking-related health problems.




     

Socioeconomic and drug use determinants of smoking status in an urban adult population of Black African descent

We examined the influence of socioeconomics and drug use on current smokers (N = 137) and nonsmokers (N = 143) from an urban adult population of Black African descent. Median participant age was 33 years (range = 20-59). Smokers consumed a median of eight cigarettes/day (range = 0-35). Interestingly, 86% smoked fewer than 15 cigarettes/day and only 8% smoked menthol cigarettes. Socioeconomic and drug use variables significantly associated with smoking status in univariate analyses were included in a multiple logistic regression model that controlled for gender and age. Compared with nonsmokers, smokers were less likely to be university educated, more likely to be divorced, separated, or widowed, more likely to be current alcohol users, and more likely to be current marijuana users. Unexpectedly, household income and employment status were not associated with smoking status. Among current alcohol users, smokers consumed three times the number of drinks per month that nonsmokers consumed (p<.001). Among current marijuana users, smokers consumed more than five times the number of joints per month that nonsmokers consumed (p<.001). Overall, lower education levels, divorce, and alcohol and marijuana use were significantly associated with increased likelihood of smoking among this population.     

Characteristics of low-level smokers.

Average daily cigarette consumption has decreased, and some evidence suggests that the rate of "some day" smoking has increased; however, relatively little is known about low-level smokers. The present analysis describes and compares low-level versus heavier smokers, using cross-sectional and longitudinal data. Data from the Community Intervention Trial for Smoking Cessation (COMMIT) were used in this analysis. Population-based cross-sectional tobacco use telephone surveys were performed in 22 North American communities in 1988 and 1993, and the prevalence and characteristics of low-level smoking and reasons for quitting are reported from the 1993 prevalence survey. In addition, a cohort of 6,603 smokers was identified in 1988 and interviewed again in 1993 and 2001 to assess patterns of low-level smoking over time and its association with smoking cessation. In 1988, 7.6% were low-level smokers; in 1993, 10.7% were low-level smokers. Compared with heavier smokers, low-level smokers were more likely to be female, older, not married, Black or Hispanic; to have a 4-year college degree; to have no other adult smokers in the household; and to wait longer in the day to have their first cigarette. Low-level smokers also were less likely to report trying to quit because of the expense of smoking or physician advice to quit. They were more likely to try to quit because of trying to set a good example; concern for second-hand smoke; and factors such as bad breath, smell, or the taste of smoking. Those who smoked full-priced premium brands and who worked in a completely smoke-free worksite were more likely to be low-level smokers. Compared with heavier smokers, low-level smokers had similar rates of making a future quit attempt, lower use rates of nicotine replacement therapy, and higher cessation rates. Low-level smokers may be a growing segment of the smoker population and have different characteristics, health risks, and intervention needs compared with their heavier smoking counterparts.     

Sociodemographic, insurance, and risk profiles of maternal smokers post the 1990s: how can we reach them?

Declines in prenatal smoking rates have changed the composition of maternal smokers while public policy during the 1990s has likely made it more difficult to reach them. Medicaid expansions during the 1980s/early 1990s insured more women some time during pregnancy, but the 1996 welfare reform unexpectedly reduced enrollment in Medicaid by eligible pregnant women; overall, insurance coverage has declined since 2000. As the public sector struggles with fewer resources, it is important to understand the sociodemographic characteristics of prenatal smokers, their patterns of care, and nonsmoking risk behaviors. Targeting scarce dollars to certain settings or sub-populations can strengthen the infrastructure for tobacco policy change. We provide more current information on maternal smokers in 2002 based on the Pregnancy Risk Assessment Monitoring System (PRAMS) for 21 states. Data on urban/rural location, insurance coverage, access patterns, and nonsmoking risk behaviors (e.g., abuse) among low-income (<16,000) and other maternal smokers are included. Low-income maternal smokers are the working poor living in predominately urban areas with fewer health care resources than low-income nonsmokers. Over 50% of low-income maternal smokers are uninsured pre-pregnancy and use a clinic as their usual source of care. Regardless of income, smokers exhibit rates of nonsmoking risks that are two to three times those of nonsmokers and high rates of unintended pregnancy (68%) of low-income smokers. These characteristics likely call for a bundle of social support services beyond cessation for smokers to quit and remain smoke-free postpartum.     

Prevalence and characteristics of smokers at 30 Pacific Northwest colleges and universities.

College is an important transition period during which young adults explore tobacco use. Few large-scale studies have been conducted among college students regarding tobacco use. We initiated a study examining tobacco use in 30 colleges and universities in the Pacific Northwest. We conducted a baseline survey among students. Sample size varied by the school size; for the 14 largest schools, we drew a random sample of all students, oversampling freshmen (n approximately 750) so that we could recruit and follow a cohort to assess smoking onset during the college years. Of the remaining students, we sampled equivalent numbers of sophomores, juniors, and seniors (n = 200 each). For the 16 schools with fewer than 1,350 students, we surveyed all students. We found overall smoking rates of 17.2%. Males (18.6%) were more likely to smoke than females (16.6%; p = .03), and public college students were more likely to smoke (20.5%) than those who attended private independent schools (18.9%; p = .61), whose rates were higher than those of private religious schools (11.6%; p = .001). Overall, college students are light smokers who do not smoke every day of the month. Further, they tend not to be highly dependent on tobacco, do not consider themselves regular smokers, and plan to quit before they graduate (56.8%). School type should be considered when estimating smoking rates among 4-year college students. Data indicate that college smokers wish and plan to quit before graduation, suggesting that efforts to assist smokers in quitting during the college years may be fruitful.
