Assigning dose of nicotine gum by time to first cigarette.

Introduction: Nicotine gum, a proven effective aid to cessation, comes in two doses: 2-mg and 4-mg. Assignment to the higher dose has traditionally been based on daily cigarette consumption. This paper evaluates efficacy of the gum when the 4-mg dose is assigned based on time to first cigarette (TTFC) being ≤ 30 min.

Front-loaded versus weekly counseling for treatment of tobacco addiction.

Introduction: Approximately 60%-70% of cigarette smokers who try to quit relapse by 2 weeks postcessation. We tested the efficacy of a front-loaded (FL) counseling intervention whose goal was to increase the likelihood of successful early abstinence and subsequent long-term abstinence.

Methods: We randomized 278 adult smokers to an FL or weekly behavioral smoking cessation counseling schedule.

Effect of compliance with nicotine gum dosing on weight gained during a quit attempt.

Aim: Using nicotine gum can reduce the amount of weight gained when quitting. Here we examine the relationship between weight gain and use of adequate amounts of gum. To mitigate the confounders associated with correlational analyses, we contrast the effects of active gum and placebo, and analyze outcomes prospectively.

A prospective study of persistence in the prediction of smoking cessation outcome: results from a randomized clinical trial.

Research has had mixed success in identifying pretreatment variables which can be used to guide treatment and enhance outcome. A critical first step in the process is to identify variables that reliably predict outcome. Some recent studies, largely retrospective, have found mixed evidence on the relationship between task persistence and smoking outcome measures.

Role of nicotine gum and pretreatment depressive symptoms in smoking cessation: twelve-month results of a randomized placebo controlled trial.

Objective: The aim was to investigate the role of nicotine gum and pretreatment depressive symptoms in long-term smoking cessation.

Methods: 12-month follow-up of 608 participants within a randomized, controlled trial was conducted. Participants received brief counseling plus nicotine or placebo treatment.

Exercise as an adjunct to nicotine gum in treating tobacco dependence among women.

This was the first randomized, controlled smoking cessation trial assessing the efficacy of an exercise intervention as an adjunct to nicotine gum therapy in comparison with both equal contact control and standard care control conditions. Sedentary female smokers aged 18-55 years were provided with nicotine gum treatment along with brief behavioral counseling and were randomized into one of these three behavioral adjunct conditions. In the "intent-to-treat" sample (N = 182), at end of treatment and at 1-year follow-up, there were clear, but nonsignificant, trends in univariate analyses in which the exercise and equal contact control conditions both had higher rates of abstinence than the standard care control.

Depression and smoking across 25 years of the Normative Aging Study.

Objective: The majority of past findings indicate that smokers are more likely than non-smokers to report depressive symptoms and that depression may act as an impediment to smoking cessation. The aim of the present study is to examine the stability of the relationship between depressive symptoms and smoking status and to determine whether the presence of depressive symptoms predicts continued smoking.

Methods: Subjects were initially healthy men (n = 2208) from the Veterans Administration Normative Aging Study, an ongoing cohort of older men who have been re-assessed every 3-5 years for a period of 25 years.

High-dose nicotine patch therapy for smokers with a history of alcohol dependence: 36-week outcomes.

This study reports findings from an investigation of the efficacy of high-dose nicotine patch (NP) therapy for heavy smokers with a history of alcohol dependence. One hundred thirty participants were randomly assigned to 42 or 21 mg of transdermal nicotine. Follow-up assessments were conducted at 4, 12, 24, and 36 weeks.

Attrition in a multi-component smoking cessation study for females.

Limiting attrition (i.e., participant dropout before the conclusion of a study) is a major challenge faced by researchers when implementing clinical trials.

Impact of Nicotine Replacement Therapy on post-cessation mood profile by pre-cessation depressive symptoms.

We evaluated the effects of Nicotine Replacement Therapy (NRT) on the Profile of Mood States (POMS), testing whether pre-cessation depressive symptoms modify NRT's effects on POMS. Out of 608 smokers attempting to quit with NRT, this secondary analysis included 242 participants abstinent for at least two weeks. We measured pre-cessation depressive symptoms with the Center for Epidemiological Studies Depression Scale.

The influence of gender, race, and menthol content on tobacco exposure measures.

Research has suggested that race, gender, and menthol cigarette use influence tobacco-smoke exposure measures and smoking-related disease risk. For example, a high proportion of Black smokers prefer menthol cigarettes and, despite smoking fewer cigarettes per day (CPD) than do Whites, tend to have higher cotinine levels. Additionally, Black males are more at risk for smoking-related lung cancer.

Cardiovascular risk behavior among sedentary female smokers and smoking cessation outcomes.

Background: We examined female sedentary smokers' additional cardiovascular disease (CVD) risk behaviors and their associations to smoking cessation.

Methods: This study was part of a randomized controlled trial testing the effectiveness of exercise and nicotine gum in smoking cessation. Included in the analyses were 148 participants.

Smoking relapse after 2 years of abstinence: findings from the VA Normative Aging Study.

Little is known about the risk of cigarette smoking relapse after 2 or more years of abstinence. The rates and predictors of late smoking relapse were estimated in 483 men who participated in a prospective study for up to 35 years. Subjects are participants in the VA Normative Aging Study, a prospective observational study of aging in men that began in 1963.
