ARE SELF-REPORTS OF SMOKING RATE BIASED? EVIDENCE FROM THE SECOND NATIONAL HEALTH AND NUTRITION EXAMINATION SURVEY

This study determined evidence for digit preference in self-reports of smoking in the Second National Health and Nutrition Examination Survey (NHANES II). Subjects were 4275 adult smokers. Self-reports of smoking showed a marked degree of digit preference, with the vast majority of smokers reporting in multiples of 10 cigarettes per day. When number per day was compared to an objective measure of smoking exposure (carboxyhemoglobin; n = 2070) the distribution was found to be significantly assymetrical. Analysis of the distribution of COHb and various levels of number per day indicates that the differences in distribution are not due to variability in COHb. Heavier smokers, Caucasians, and those with less education were more likely to report a digit preference than lighter smokers. African-Americans, and those with more education. Results suggest that self-reports of number of cigarettes per day may be biased towards round numbers (particularly 20 cigarettes per day). Implications for assessment of smoking behavior are discussed.

Relationships among smoking status, ethnicity, socioeconomic indicators, and lifestyle variables in a biracial sample of women

BACKGROUND Smoking prevalence rates remain high among women and smoking initiation has increased for young adults. Little is known about the unique patterns of smoking, risk factors, and correlates of quitting in Black versus White women of child-bearing age. METHOD This study examined the relationships among smoking, ethnicity, socioeconomic status (SES), and lifestyle variables among 715 women (43.6% Blacks and 56.4% Whites). Stringent inclusion criteria were used for ethnicity, which allows for distinct comparisons but may reduce generalizability of results. RESULTS Black current smokers smoked fewer cigarettes per day and reported initiating smoking at a later age than Whites. Current versus never smoking was associated with income, education, and caffeine intake. There was a significant ethnicity by alcohol interaction (at lower levels of alcohol intake Whites were more likely to smoke but at higher levels of alcohol there were no ethnic differences). Former smoking versus current smoking was associated with alcohol intake, education, and pack years of smoking. CONCLUSIONS The results of the study suggest several ethnic differences in smoking patterns as well as several correlates of smoking status. These results have implications for the tailoring of interventions and illustrate the association of other health risk factors with smoking status.

The validity of self-rated health as a measure of health status among young military personnel: Evidence from a cross-sectional survey

BackgroundSingle item questions about self ratings of overall health status are widely used in both military and civilian surveys. Limited information is available to date that examines what relationships exist between self-rated health, health status and health related behaviors among relatively young, healthy individuals.MethodsThe current study uses the population of active duty United States Air Force recruits (N = 31,108). Participants completed surveys that asked about health behaviors and health states and were rated their health on a continuum from poor to excellent.ResultsRatings of health were consistently lower for those who used tobacco (F = 241.7, p < .001), reported binge drinking (F = 69.0, p < .001), reported drinking and driving (F = 19.4, p < .001), reported taking health risks (F = 109.4, p < .001), were depressed (F = 256.1, p < .001) and were overweight (F = 39.5, p < .001).ConclusionGiven the consistent relationship between self-rated overall health and factors important to military health and fitness, self-rated health appears to be a valid measure of health status among young military troops.

Efficacy of a Tailored Tobacco Control Program on Long-Term Use in a Population of U.S. Military Troops.

The authors evaluated the effect of a brief tailored smoking control intervention delivered during basic military training on tobacco use in a population of military personnel (N = 33,215). Participants were randomized to either a tobacco use intervention (smoking cessation, smokeless tobacco use cessation, or prevention depending on tobacco use history) or a health education control condition. Results indicated that smokers who received intervention were 1.16 (95% confidence interval [CI] = 1.04, 1.30) times (7-day point prevalence) and 1.23 (95% CI = 1.07, 1.41) times (continuous abstinence) more likely to be abstinent than controls from smoking cigarettes at the 1-year follow-up (p < .01); the cessation rate difference was 1.60% (31.09% vs. 29.49%) and 1.73% (15.47% vs. 13.74%) for point prevalence and continuous abstinence, respectively. Additionally, smokeless tobacco users were 1.33 (95% CI = 1.08, 1.63) times more likely than controls (p < .01) continuously abstinent at follow-up, an overall cessation rate difference of 5.44% (33.72% vs. 28.28%). The smoking prevention program had no impact on smoking initiation. These results suggest potential for large-scale tobacco control efforts.

Symptomatology across the menstrual cycle in smoking and nonsmoking women

Recent studies suggest that both smoking rates and general menstrual symptomatology increase in women premenstrually; however, no study has investigated the changes in menstrual symptomatology and smoking behavior in both smoking and nonsmoking women over an entire menstrual cycle. Thirty premenopausal women completed daily symptom checklists over an entire menstrual cycle. Smokers also recorded their smoking behavior. Results indicated that symptom severity was greatest during menses for both smoking and nonsmoking women. For cigarette consumption, analyses indicated that women smokers appear to smoke more during menses and the luteal phases than ovulation and that variability in smoking was greatest premenstrually. In summary, results indicated that general menstrual symptomatology increases during menses and the late luteal phase and that smoking-deprivation symptomatology increase in both smokers and nonsmokers. This suggests that smokers may have a difficult time quitting during menses or the luteal phase of their cycle.

Tobacco Use Harm Reduction, Elimination, and Escalation in a Large Military Cohort

OBJECTIVES We evaluated changing patterns of tobacco use following a period of forced tobacco abstinence in a US military cohort to determine rates of harm elimination (e.g., tobacco cessation), harm reduction (e.g., from smoking to smokeless tobacco use), and harm escalation (e.g., from smoking to dual use or from smokeless tobacco use to smoking or dual use). METHODS Participants were 5225 Air Force airmen assigned to the health education control condition in a smoking cessation and prevention trial. Tobacco use was assessed by self-report at baseline and 12 months. RESULTS Among 114 baseline smokers initiating smokeless tobacco use after basic military training, most demonstrated harm escalation (87%), which was 5.4 times more likely to occur than was harm reduction (e.g., smoking to smokeless tobacco use). Harm reduction was predicted, in part, by higher family income and belief that switching from cigarettes to smokeless tobacco is beneficial to health. Harm escalation predictors included younger age, alcohol use, longer smoking history, and risk-taking. CONCLUSIONS When considering a harm reduction strategy with smokeless tobacco, the tobacco control community should balance anticipated benefits of harm reduction with the risk of harm escalation and the potential for adversely affecting public health.

Ethnic and gender differences in smoking and smoking cessation in a population of young adult air force recruits.

Purpose. To examine gender and ethnic differences in smoking and smoking cessation in a population of young adult military recruits. Design. A self-administered survey of demographics, tobacco use, and other health risk behaviors was administered at the start of basic military training. Setting. The study was conducted at Lackland Air Force Base, San Antonio, Texas, where all U.S. Air Force recruits complete basic military training. Subjects. All recruits who entered the U.S. Air Force between September 1995 and September 1996 participated in this study (n = 32,144; 100% participation rate). Measures. Recruits completed a written 53-item behavioral risk questionnaire. Measures examined in the present study included smoking status (ever having smoked a cigarette, current daily smoking, and quitting); demographics (ethnicity, gender, education, family income, and age); smoking history; and nicotine dependence. Results. Rates of ever smoking, current daily smoking, and quitting were examined in multiple logistic regression analyses as a function of gender and ethnicity, controlling for age, education, and family income. Overall, 54% of recruits had ever smoked a cigarette and 24.9% smoked daily at the time of entry into basic military training. Smoking rates were highest among white and Native American recruits. Among whites, women were more likely to be a current daily smoker (31.6% vs. 29.4%; odds ratio [OR] = 1.18, 99% confidence intervals [CI] = 1.08–1.29). The opposite pattern was observed among African-Americans (5.6% vs. 9.8%, respectively; OR = .57; CI = .41–.79). Current smokers had low levels of nicotine dependence compared with the general population of U.S. smokers, but whites tended to be more dependent than other ethnic groups. Cessation rates were similar for men and women but differed according to ethnicity, ranging from 15% among whites to 23% among Hispanics. Conclusions. These findings document important gender and ethnic differences in cigarette smoking among military recruits. Whites and Native Americans were more likely to smoke, less likely to quit, and more nicotine-dependent than other ethnic groups. Across gender/ethnicity groups, smoking rates were especially high among white women, with nearly one-third smoking daily until entry into basic training. Gender differences were not observed in cessation rates, but Hispanics were more likely than other ethnic groups to have quit smoking. The results highlight the need to develop effective cessation interventions for this population.

Differences between intermittent and light daily smokers in a population of U.S. military recruits.

INTRODUCTION Few studies have assessed differences between intermittent and light smokers, particularly among young adults. Exploring these differences promotes a systematic approach to research and treatment in low-level smokers. This study explored demographic, tobacco-related, and psychosocial predictors of intermittent nondaily smoking relative to light smoking among basic military training (BMT) recruits. The impact of smoking status on abstinence rates at follow-up was also assessed. METHODS Participants were 5,603 U.S. Air Force BMT intermittent nondaily (n = 3,134) or light daily (n = 2,469) smoking recruits participating in a population-based group randomized trial targeting tobacco use prevention and cessation (Klesges et al., 2006, Efficacy of a tailored tobacco control program on long-term use in a population of U.S. military troops. Journal of Consulting and Clinical Psychology, 74, 295-306.). Participants completed baseline measures assessing demographics; tobacco use and history; and common social, attitudinal, and behavioral risk factors for tobacco use. Flights of recruits were randomly assigned to a tobacco use intervention or health education control intervention. At the 1-year follow-up, participants reported 7-day point prevalence and continuous abstinence. RESULTS Intermittent nondaily smoking relative to light daily smoking was associated with lesser perceived addiction, intermittent and daily use of smokeless tobacco, nonsmoking male and female heads of household, lesser likelihood of smoking while stressed or while bored, and higher likelihood of intentions to quit smoking. Intermittent smokers were significantly more likely than light daily smokers to report abstinence at follow-up. DISCUSSION Intermittent and daily light smokers differ on several tobacco-related and psychosocial variables. Attending to these factors in prevention and cessation programs may enhance abstinence in both groups.

Psychiatric disorders and cognitive dysfunction among older, postmenopausal women: results from the Women's Health Initiative Memory Study.

OBJECTIVE To estimate the frequency of depressive symptoms and selected psychiatric disorders in the Womens Health Initiative Memory Study (WHIMS) cohort and related them to cognitive syndromes. DESIGN WHIMS was a randomized, double-blinded, placebo-controlled prevention clinical trial examining whether opposed and unopposed hormone therapy reduced the risk of dementia in healthy postmenopausal women. Participants scoring below a designated cutpoint on a cognitive screener received a comprehensive neuropsychiatric workup and adjudicated outcome of no cognitive impairment, mild cognitive impairment, or probable dementia. PARTICIPANTS Seven thousand four hundred seventy-nine WHIMS participants between age 65 and 79 years and free of dementia at the time of enrollment in WHIMS. Five hundred twenty-one unique participants contributed complete data required for these analyses. MEASURES Depressive symptoms were measured with the 15-item Geriatric Depression Scale and the presence of selected psychiatric disorders (major depression, generalized anxiety, and panic and alcohol abuse) was made using the PRIME-MD. RESULTS The 18% of women had at least one psychiatric disorder with depression being the most common (16%) followed by general anxiety or panic (6%) and alcohol abuse (1%). Depression and the presence of a psychiatric disorder were associated with impaired cognitive status. Participants having a psychiatric disorder were more than twice as likely to be diagnosed with cognitive impairment as those with no psychiatric disorder (odds ratio = 2.06, 95% confidence interval = 1.17-3.60). Older age, white race, and diabetes were also associated with cognitive impairment. CONCLUSION The frequency of a psychiatric disorder is associated with poorer cognitive functioning among older women enrolled in WHIMS. That approximately one in five women had a probable psychiatric disorder, most typically depression, highlights the need for greater detection and treatment efforts in this population.

Smoking cessation: A successful behavioral/pharmacologic interface

Abstract Cigarette smoking is the single most preventable cause of premature mortality in this country. Fortunately, there are both behavioral and pharmacological approaches that are effective in long-term smoking cessation. The purpose of this review will be first to highlight the short- and long-term effectiveness of behavioral, pharmacological, and combined approaches to smoking cessation. We will review what is known about the mechanisms of change in both behavioral and pharmacological treatments. Adherence to both approaches will be highlighted and cost-effectiveness issues will be discussed. It will be concluded that despite the relatively high cost per confirmed long-term quit smoker, smoking cessation is an area in which a high degree of cost effectiveness can be demonstrated.
