Weight gain as a function of smoking cessation and 2-mg nicotine gum use among middle-aged smokers with mild lung impairment in the first 2 years of the Lung Health Study.

Assessed the extent and predictors of weight change among sustained nonsmoking special intervention participants in the Lung Health Study. The intervention included a 12-session group program and 2-mg nicotine gum. At 12 mo, female sustained quitters (SQs; n?=?248) had gained a mean of 8.4% (5.3 kg) of their baseline weight, whereas male SQs (n?=?443) had gained 6.7% (5.5 kg). By 24 mo, female SQs had gained 9.8% of their baseline weight compared with 6.9% for men. Nicotine gum usage delayed a portion of the weight gain. Multiple regression analysis showed that weight gain at 12 mo was associated with a higher baseline salivary cotinine level, a lower baseline body mass index, drinking less alcohol per week, and a lower cotinine level at 12 mo (indicating less or no nicotine gum use). Moderate weight gain may be a long-term consequence of smoking cessation, a portion of which can be delayed with 2-mg nicotine gum. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eating orientation, postcessation weight gain, and continued abstinence among female smokers receiving an unsolicited smoking cessation intervention.

Predictors of weight gain following smoking cessation were assessed among 1,219 female smokers enrolled in a health maintenance organization. Women randomized to the treatment group received a cessation intervention without regard to their interest in quitting smoking. It was hypothesized that cessation would result in subsequent weight gain and postcessation weight gain would be associated with scores on a modified Restraint Scale, the Disinhibition Scale, and a scale assessing tendency to eat during periods of negative affect. Persons who abstained from smoking over the 18-month study gained more weight than did intermittent smokers and continuous smokers, and among 762 women who reported at least 1 on-study attempt to quit smoking, 36% gained weight. Weight gain was associated with disinhibited eating and negative affect eating but not with restrained eating. Weight gain also was associated with continued abstinence from smoking.

Partner smoking status and pregnant smoker's perceptions of support for and likelihood of smoking cessation.

Perceptions of support for cessation of smoking during pregnancy, likelihood of quitting, and partner smoking status were explored in a sample of 688 pregnant smokers (372 baseline smokers and 316 baseline quitters). Women with nonsmoking partners were significantly more likely to be baseline quitters than women with partners who smoked. Baseline quitters reported significantly more positive support from their partners than did continuing smokers (p?=?.02). Neither partner smoking status nor partner support at baseline was associated with cessation or relapse later in pregnancy. Women reported greater support, both positive and negative, from nonsmoking partners than from partners who smoked (p?=?.001). Among partner smokers, those who were trying to quit were perceived to be particularly supportive. Cessation interventions for expectant fathers may increase pregnant women's success at quitting.

Written personalized feedback and confidence in smoking cessation.

Examines the relationship among written personalized feedback, smokers' confidence, and smoking cessation with 1,217 smokers participating in a randomized trial. There were higher quit rates among smokers with lower levels of baseline confidence, and greater increases in confidence from baseline to 3 mo among smokers who quit. Personalized feedback had its largest impact on confidence early in the cessation process, and the impact was reflected in sustained increases in confidence among quitters through a 1-yr follow-up. The feedback had no effect on the confidence of smokers who did not achieve initial cessation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of culturally specific cessation messages on theoretical antecedents of behavior among low-income african american smokers.

Previous research has highlighted the importance of cultural relevance in health risk communications, including tobacco interventions. However, few studies have examined the active components of smoking cessation messages targeting low-income African American smokers. This study tested the influence of message content and culturally specific framing in a sample of adult smokers. In a 2 × 2 factorial experiment, 243 African American smokers (M = 19 cigarettes/day) recruited from the community (55% women; mean age = 43 years) were randomly assigned to 1 of 4 conditions: culturally specific smoking messages, standard smoking messages, culturally specific exercise/weight messages, or standard exercise/weight messages. The primary outcome measures were theoretical antecedents to behavior change, including risk perceptions (general, personal, and culturally specific), readiness to quit smoking, and smoking-related knowledge. The results showed that the smoking messages produced greater culturally specific risk perceptions, readiness to quit smoking, and smoking-related knowledge. The culturally specific messages produced greater personal risk perceptions and intentions to quit. Culturally specific risk perceptions were most affected by culturally specific smoking messages. Findings support the roles of message content and culturally specific framing in the efficacy of brief written interventions for smoking cessation in this population. Future research is needed to examine the influence of these constructs on behavior change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The prospective relationships between smoking and weight in a young, biracial cohort: the Coronary Artery Risk Development in Young Adults Study

This study examined the relationship between smoking status and weight change from baseline to Year 7 in a large biracial cohort, the Coronary Artery Risk Development in Young Adults study. Unadjusted for covariates, only male smokers weighed less than nonsmokers, with no effect among women. Adjusted for covariates, male and female smokers weighed less than nonsmokers at baseline, adjusted for age, total energy intake, alcohol intake, and physical fitness. Over the 7-year follow-up, all smoking status groups gained weight, including continuous smokers and initiators. Weight gain was greatest among those who quit smoking. Weight gain attributable to smoking cessation was 4.2 kg for Whites and 6.6 kg for Blacks. Smoking had a small weight-attenuating effect on Blacks. No such effects, however, were observed among Whites. These results suggest, at least in younger smokers, that smoking has minimal impact on body weight.     

Cognitive–behavioral therapy to reduce weight concerns improves smoking cessation outcome in weight-concerned women.

Women smokers concerned about weight gain (N?=?219) were randomly assigned to 1 of 3 adjunct treatments accompanying group smoking cessation counseling: (a) behavioral weight control to prevent weight gain (weight control); (b) cognitive–behavioral therapy (CBT) to directly reduce weight concern, in which dieting was discouraged; and (c) standard counseling alone (standard), in which weight gain was not explicitly addressed. Ten sessions were conducted over 7 weeks, and no medication was provided. Continuous abstinence was significantly higher at posttreatment and at 6 and 12 months of follow-up for CBT (56%, 28%, and 21%, respectively), but not for weight control (44%, 18%, and 13%, respectively), relative to standard (31%, 12%, and 9%, respectively). However, weight control, and to a lesser extent CBT, was associated with attenuation of negative mood after quitting. Prequit body mass index, but not change in weight or in weight concerns postquit, predicted cessation outcome at 1 year. In sum, CBT to reduce weight concerns, but not behavioral weight control counseling to prevent weight gain, improves smoking cessation outcome in weight-concerned women.

Relationship between grade and stage of renal pelvic and/or ureteral tumor and associated bladder tumor

The use of proxy respondents in surveys designed to provide population estimates of smoking prevalence offers an inexpensive way to obtain these data. The accuracy of this information is examined in analyzing data from tobacco use surveys of adults conducted in 22 North American communities as part of the National Cancer Institute's Community Intervention Trial for Smoking Cessation. Proxy-reported smoking status was obtained in a cross-sectional telephone survey conducted from August 1993 to January 1994 (n = 99,682). Self-reported smoking status was obtained from an in-depth interview of a sample of the respondents aged 25-64 years enumerated from the telephone survey (n = 31,417). Discrepancy rates were calculated by comparing the proxy-reported and self-reported smoking statuses of a given individual (n = 10,226). In both surveys, respondents were categorized as current smokers (those who currently smoke and have smoked at least 100 cigarettes in their lifetime), recent quitters (< or = 8 years since cessation), long-term quitters (> 8 years since cessation), and never smokers. The overall discrepancy rate between the self-report and the proxy report was 5.4%. Self-respondents who were black, Hispanic, Asian, recent quitters, or aged 25-34 years were more likely to have inconsistent proxy reports. The authors estimate that the screener interview underestimated the true smoking prevalence by 0.1% when they corrected for smoking status discrepancies. These results confirm that proxy-reported smoking status is an accurate and effective means to monitor populationwide smoking prevalence of adults.     

Smoking-specific weight gain concerns and smoking cessation in a working population.

Smoking cessation rates, progression in stage of change for smoking cessation, and serious quit attempts were examined over 2 years in a cohort of 242 men and women smokers (mean age 39.7 years, mean body mass index [BMI] 26.3) as a function of expressing concern about gaining weight because of quitting smoking. Participants were employees of 25 companies who were in a worksite health promotion program aimed at reducing risk factors for cardiovascular disease. Multivariate odds ratios (controlled for age, education, job class, sex, and BMI) for quitting smoking, attempting to quit smoking, and progressing in stage of change for smoking cessation as a function of weight concern were not significant. Interactions between sex and weight concern, and BMI and weight concern were also not significant. These findings, in a working, predominantly blue-collar population, and those of other studies, suggest that concern about gaining weight is, at best, a weak predictor of change in smoking behavior among most smokers.

Stress, depressive symptoms, and smoking cessation among pregnant women.

Perceived stress and depressive symptoms were examined as correlates and predictors of smoking cessation during pregnancy in a sample of 819 pregnant smokers (454 baseline smokers and 365 baseline quitters). Women who quit early in pregnancy had lower levels of stress and depressive symptoms than baseline smokers. Adjusting for level of addiction and other demographic factors related to stress and depressive symptoms eliminated the significant association between depressive symptoms and smoking cessation. Lower levels of stress and depressive symptoms were not predictive of cessation in later pregnancy. Prenatal healthcare providers should continue to assess level of addiction and provide targeted intensive cessation interventions. Interventions that reduce stress and depression may also be of benefit to women who are continuing smokers in early pregnancy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Motivation for smoking cessation among pregnant women.

The authors evaluated an expanded measure of intrinsic and extrinsic motivation for smoking cessation in a population-based sample of 897 pregnant smokers (500 current smokers and 397 recent quitters). The measure assessed motivation related to pregnancy and parenthood in addition to general intrinsic and extrinsic dimensions. Current smokers at baseline who quit smoking by 28 weeks of pregnancy (n?=?102) had significantly higher baseline levels of pregnancy-related motivation than continuing smokers. Extrinsic and pregnancy motivation dropped between baseline and 28 weeks of pregnancy among continuing smokers. Higher levels of intrinsic relative to extrinsic motivation at baseline were associated with sustained abstinence during the first 2 months postpartum. Results suggest that both general and pregnancy-specific motivation are important for smoking cessation and relapse prevention during pregnancy. Interventions to enhance the salience of health benefits over and above those related to pregnancy and other intrinsic benefits of a greater sense of self-control could protect against postpartum relapse.

Changes in self-efficacy resulting from unaided attempts to quit smoking.

Investigated changes in smoking self-efficacy as a result of successful and unsuccessful quit attempts. The sample consisted of 182 smokers (aged 19–70 yrs) who planned to quit smoking without professional assistance. Prior to a self-selected quit date, smoking self-efficacy was assessed. Quit status was determined 1, 6, and 12 mo after the quit date. Self-efficacy was reassessed at the 12-mo follow-up. At 12 mo the sample consisted of 44 quitters, 24 continuous smokers, 102 relapsers, and 12 Ss whose smoking status was uncertain. Self-reports of cessation were corroborated by collateral report and confirmed by saliva cotinine analysis. As predicted, quitters increased their self-efficacy, and continuous smokers decreased their self-efficacy from the prequit baseline to the 12-mo follow-up. Relapsers' self-efficacy also dropped significantly. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Is weight gain after smoking cessation inevitable?

Weight gain after smoking cessation was studied in a naturalistic setting where (1) all smokers quit and (2) risk factors for postcessation weight gain were modified. Participants were 332 military recruits (227 men, 105 women), 86 of whom were smokers who quit during 6 weeks of basic training. Results showed no significant weight changes for smokers who quit. Pretest smoking rates and feat of weight gain were unrelated to changes in weight. Results suggest that an intensive program that limits access to alcohol and foods that are high in fat and that increases physical activity can attenuate weight gain after smoking cessation.

Stress and unaided smoking cessation: A prospective investigation.

A prospective design was used to determine the outcomes associated with unaided smoking cessation and the influence of stress on cessation. Heavy smokers (N?=?308) completed stress-related measures and were then recontacted at 1, 6, and 12 mo. At each follow-up, they indicated their smoking status (which was confirmed by collateral report and biochemical tests) and completed several stress-related questionnaires. Results indicate that 33% of Ss smoked continuously throughout the year, 39% quit briefly but subsequently relapsed, and 15% quit (confirmed biochemically). An additional 7% reported they had quit, but this could not be confirmed, and 6% were lost to follow-up. Compared with nonquitters, quitters reported less perceived stress, greater self-efficacy, greater use of problem solving and cognitive restructuring, and less reliance on wishful thinking, self-criticism, and social withdrawal. A model to forecast quitting was built and cross-validated. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Long-term psychological sequelae of smoking cessation and relapse.

The authors examined whether smoking cessation and relapse were associated with changes in stress, negative affect, and smoking-related beliefs. Quitters showed decreasing stress, increasing negative health beliefs about smoking, and decreasing beliefs in smoking's psychological benefits. Quitters became indistinguishable from stable nonsmokers in stress and personalized health beliefs, but quitters maintained stronger beliefs in the psychological benefits of smoking than stable nonsmokers. Relapse was not associated with increases in stress or negative affect. However, relapsers increased their positive beliefs about smoking and became indistinguishable from smokers in their beliefs. For quitters, decreased stress and negative beliefs about smoking may help maintain successful cessation. However, for relapsers, declining health risk perceptions may undermine future quit attempts.

The relationship between smoking and body weight in a population of young military personnel.

Evidence indicates that middle-aged smokers weigh less than nonsmokers and that smoking cessation reliably produces weight gain, but recent studies have questioned the weight control "benefits" of smoking in younger populations (the time that people typically initiate smoking). The relationship between smoking and body weight was evaluated in all U.S. Air Force Basic Military Training recruits during a 1-year period (n?=?32,144). Those who smoked prior to Basic Military Training (n?=?10,440) were compared to never smokers or experimental smokers. Results indicated that regular-current smoking had no relationship to body weight in women (p? >?.05) and a very small effect in men (p?     

Sex dfferences in the relation of mood to weight gain after quitting smoking.

Weight gain with smoking cessation is well documented. In this study the authors explored the impact of mood state on weight gain after quitting. Data of 350 participants enrolled in 2 smoking cessation trials were analyzed; primary analyses assessed the relation of affective factors to weight gain in abstinent participants only. Weight gain was predicted by abstinence status. Depression history, gender, and mood change from pre- to postcessation assessments were included in a model predicting weight gain in abstinent participants at the end of smoking cessation treatment (N?=?201) and at 1-year follow-up (N?=?87). At posttreatment, depression history positive women gained more than depression negative women, whereas depression history positive men gained less than depression history negative men. At 1-year follow-up, weight gain was predicted by improved mood in "normal" men and by worsened mood in both depression history positive and negative women.

Stages of acquisition and cessation for adolescent smoking: an empirical integration

Adolescent cigarette smoking acquisition and cessation were integrated into a single nine-stages-of-change continuum using the transtheoretical model of change framework. Findings in a high school student sample (n > 700) showed that a few of the never smokers were planning to try smoking, and half of the current smokers were contemplating quitting. More than half of former smokers were long-term quitters. The high pros of smoking scores assessing coping benefits of cigarettes were related to smoking acquisition and the high con (disadvantages) scores to long-term abstinence. Never smokers were most tempted to try smoking when they anticipated that smoking would help reduce negative and increase positive mood. Current and former smokers were tempted due to peer cigarette offers and negative mood. These temptations were significantly reduced among ex-smokers.     

Passive smoking, active smoking, and education: their relationship to weight history in women in Geneva

OBJECTIVES: This study was undertaken to determine the relationship of education and tobacco smoke to lifetime weight history in women. METHODS: Information on passive smoking, active smoking, and weight history was collected from 928 women aged 29 to 74 years selected from the general population of Geneva, Switzerland. Multivariate analysis of variance was performed for weight, weight at age 20, and weight changes since age 20. RESULTS: Education was inversely related to weight at age 20, current weight, and weight gain since age 20. The least educated group had a current weight of 4 kg more than the most educated group. Differences across smoking categories were small: passive smokers had the highest current weight (63.4 kg) and former active smokers had the lowest (60.4 kg). Weight gain since age 20 tended to be smaller in former and current active smokers (5.5 to 7.2 kg) than in passive smokers (8.3 to 10.4 kg) and those never exposed (9.1 kg). CONCLUSIONS: In this sample, education was an important predictor of women's current weight and weight history. Passive and active smoking had little long-term effect on weight.     

Characteristics of smokers who attempt to quit and of those who recently succeeded

Although a high percentage of smokers attempt to quit each year, success rates are low. Thus, public health strategies must not only convince some smokers to attempt cessation, but also improve the success rate among other smokers already motivated to quit. Specific cessation strategies may be required for smokers in these two groups. This study compares sociodemographic and health behavior characteristics of smokers who have and have not attempted to quit and of those who recently succeeded. To determine whether these characteristics vary for men and women, we stratified analyses on gender. Data were obtained from random sample health surveys conducted 1981-1982 and 1983-1984 in two New England communities. Analyses include data on 2,086 respondents who reported smoking cigarettes in the previous year. Men and women were equally likely both to attempt cessation and to quit. Except for an inverse association with age, attempting to quit was not associated with sociodemographic variables. In men and women, attempts were associated with encouraging others to quit and attempting to increase exercise. Successful cessation attempts were associated with not living with a smoker in women; marital status, attempted weight loss, and increased age in men; and with efforts to increase exercise in both men and women. These characteristics could be useful in targeting smokers who attempt to quit, but fail. Improving the success rate in this group could greatly reduce smoking prevalence in the community.
