Estimates of postcessation weight gain vary widely. This study determined the magnitude of weight gain in a cohort using both point prevalence and continuous abstinence criteria for cessation. Participants were 196 volunteers who participated in a smoking cessation program and who either continuously smoked (n = 118), were continuously abstinent (n = 51),(More)
Participants in an 8-session, community based smoking cessation intervention rated whether they would stay quit if they experienced weight gain. The majority reported that they would not relapse to smoking, even after a 20-lb, (9.07-kg) weight gain. Those who were weight concerned were more likely to be female, to weight less and be normal or underweight,(More)
The present experiment examined effects of nicotine on body weight of male and female rats when Oreo cookies, potato chips, laboratory chow, and water were available. Body weight and eating behavior were measured for 17-day periods before, during, and after nicotine or saline administration. There was an inverse relationship between nicotine and body(More)
Nicotine administration and cessation have greater effects on body weight and eating behavior in female than in male rats. These generalizations are based on studies of body weight and eating behavior for 2–3 week periods before, during, and after nicotine administration. Therefore, the sex differences may reflect differences in sensitivity to nicotine or(More)
Women often report that they smoke cigarettes to avoid weight gains and that they relapse after abstaining from tobacco because of weight gains. Men also report these concerns but to a lesser extent. This gender difference may reflect sociological and cultural pressures about physical appearance, or it may reflect sex differences in the effects of nicotine.(More)
The present study was designed to determine whether depressive symptoms are independently associated with smoking and nicotine dependence among cigarette smokers, using 1990-1991 data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. A total of 3,933 participants (788 black men, 1,090 black women, 974 white men, and 1,081 white(More)
This study sought to determine whether depressive symptoms and/or platelet serotonin receptor (5HT2A) density are associated with increased platelet activation (PA) found among smokers. Flow cytometric detection of PA was used to study 36 smokers and 16 nonsmokers, aged 18 to 48 years. Subjects were tested at baseline and after either smoking 2 cigarettes(More)
The present study was conducted to determine if phenylpropanolamine (PPA) administered during the first week of nicotine termination could reduce or eliminate the body weight rebound which accompanies nicotine cessation. Sprague-Dawley rats were administered nicotine for 2 weeks after which they received either PPA or saline for 1 week. Control animals(More)
The effects of physical and psychological stress on circulating nicotine levels and conversion of nicotine to cotinine were examined in the rat. Animals received one of three dosages of nicotine (0, 6, and 12 mg/kg) via miniosmotic pumps. On day 14 of drug infusion, animals from each drug condition were randomly assigned to one of three stress conditions(More)
The present study determined the effect of chronic PPA infusion and withdrawal on weight regulation. Male Sprague-Dawley rats received PPA (0, 90 or 180 mg/kg) via miniosmotic pumps for 2 weeks. Body weight and food and water consumption were measured daily before, during, and for 2 weeks after PPA infusion. Additionally, body weight was measured once 6(More)
