Individual variation in psychological and psychomotor symptoms following smoking cessation: the implications for treatment

Some commonly experienced signs and symptoms occur during abstinence from tobacco, but specific signs and symptoms and their intensity vary greatly from individual to individual. The aim of this study was to re-examine psychological and psychomotor symptoms in smokers in the general population, and to explore the individual variation in these. Quitting smokers (n = 123) reported their experiences pre- and post-cessation, on a questionnaire developed for the study. Analysis of variance and frequency analysis showed significant decreases between pre- and post-cessation on positive experiences (F = 9.81, p < 0.0001) but no significant change on negative experiences, suggesting a loss of pleasure rather than increased negative affect upon quitting. The variance of the pre- to post-cessation difference score suggested wide variation in the reporting of withdrawal symptoms. These results lead us to consider the implications for treatment, using cognitive therapies and moderating the significant emphasis that is at present put on withdrawal.

Attribution and the effects of expectancy: how beliefs can influence the experiences of smoking cessation

Research on smoking cessation has found consistencies and similarities during abstinence, but also that the specific signs and symptoms and their intensity vary greatly from individual to individual. One possible source of this variation is the cognitions associated with quitting. We investigated the experiences and associated cognitions in normal cessation by asking quitting smokers to rate their experiences on a questionnaire and to indicate the most likely reason for each experience. Statistical analyses confirmed that attributions to abstinence were significantly higher for increased negative experiences, and there were significantly more reattributions than would be found by chance for items associated with smoking abstinence. Significantly more attributions to abstinence were made by clinic attendees and significantly more attributions of negative experiences to abstinence were made by unaided quitters using self-help materials. These results can be interpreted in the context of attribution theory; quitters may use the cognitions available to them to attribute their negative experiences to quitting. Consequently, counsellors could use cognitive therapy to alter their clients' expectations and explanations of their experiences, and emphasise the positive outcomes of cessation.

Anxious adults vs cool children: children's view on smoking and addiction

Tobacco addiction represents a major public health problem, and most addicted smokers take up the habit during adolescence. We need to know why. With the aim of gaining a better understanding of the meanings smoking and tobacco addiction hold for young people, 85 focused interviews were conducted with adolescent children from economically deprived areas of Northern Ireland. Through adopting a qualitative approach within the community rather than the school context, the adolescent children were given the opportunity to freely express their views in confidence. Children seem to differentiate conceptually between child smoking and adult smoking. Whereas adults smoke to cope with life and are thus perceived by children as lacking control over their consumption, child smoking is motivated by attempts to achieve the status of cool and hard, and to gain group membership. Adults have personal reasons for smoking, while child smoking is profoundly social. Adults are perceived as dependent on nicotine, and addiction is at the core of the children's understanding of adult smoking. Child smoking, on the other hand, is seen as oriented around social relations so that addiction is less relevant. These ideas leave young people vulnerable to nicotine addiction. It is clearly important that health promotion efforts seek to understand and take into account the actions of children within the context of their own world-view to secure their health

Smoking and symbolism: children, communication and cigarettes

Health promotion, with its concern with empowerment and autonomy, must recognize the agency of its target population. Based on 85 in-depth interviews with 10- to 11-year-old children throughout Northern Ireland, this paper argues that it is necessary to focus on the social relations of children if we are to understand and prevent childhood smoking. Addressing the complex issue of childhood agency, it is argued that regardless of various restrictions to their choices, children can act intentionally in constructing their identities. Instead of viewing the smoking children as communicating with the adult world, we focus on smoking as negotiation of status within the children's culture. Such negotiations utilize symbolism derived from and shared with the `adult world'. It is important that those analyzing children's lives understand children's ideas and behaviour on their own terms. We must make sure that the very concepts in which the children's experiences are put are appropriate ones. It is suggested that the metaphor `rite of passage' and terminology such as peer `pressure' versus adult `influence', commonly used to analyse the children's smoking behaviour, may actually conceal important aspects of childhood agency.

Exposure to fine particulate matter in ten night clubs in Athens Greece: studying the effect of ventilation, cigarette smoking and resuspension

The aim of the present work is to study the occupants' exposure to fine particulate concentrations in ten nightclubs (NCs) in Athens, Greece. Measurements of PM1 and PM 2.5 were made in the outdoor and indoor environment of each NC. The average indoorPM1 andPM 2.5 concentrations were found to be 181.77 μgm−3 and 454.08 μg m−3 respectively, while the corresponding outdoor values were 11.04 μg m−3 and 32.19 μg m−3. Ventilation and resuspension rates were estimated through consecutive numerical experiments with an indoor air quality model and were found to be remarkably lower than the minimum values recommended by national standards. The relative effects of the ventilation and smoking on the occupants' exposures were examined using multiple regression techniques. Itwas found that given the low ventilation rates, the effect of smoking as well as the occupancy is of the highest importance. Numerical evaluations showed that if the ventilation rates were at the minimum values set by national standards, then the indoor exposures would be reduced at the 70% of the present exposure values.

Associations of dietary dark-green and deep-yellow vegetables and fruits with cervical intraepithelial neoplasia: modification by smoking

Smoking has been positively and fruit and vegetable intake has been negatively associated with cervical cancer, the second most common cancer among women worldwide. However, a lower consumption of fruits and reduced serum carotenoids have been observed among smokers. It is not known whether the smoking effect on the risk of cervical neoplasia is modified by a low intake of fruits and vegetables. The present study examined the combined effects of tobacco smoking and diet using a validated FFQ and serum carotenoid and tocopherol levels on cervical intraepithelial neoplasia grade 3 (CIN3) risk in a hospital-based case-control study conducted in Sao Paulo, Brazil, between 2003 and 2005. The sample comprised 231 incident, histologically confirmed cases of CIN3 and 453 controls. A low intake (<= 39 g) of dark-green and deep-yellow vegetables and fruits without tobacco smoking had a lesser effect on CIN3 (OR 1.14; 95% CI 0.49, 2.65) than among smokers with higher intake (>= 40 g; OR 1.83; 95% CI 0.73, 4.62) after adjusting for confounders. The OR for the joint exposure of tobacco smoking and low intake of vegetables and fruits was greater (3.86; 95% CI 1.74, 8.57; P for trend < 0.001) compared with non-smokers with higher intake after adjusting for confounding variables and human papillomavirus status. Similar results were observed for total fruit, serum total carotene (including beta-, alpha-and gamma-carotene) and tocopherols. These findings suggest that the effect of nutritional factors on CIN3 is modified by smoking.

Marketing Social Change: A Comparative Historical and Methodological Analysis of Anti-Smoking Endeavors

Even though assessing social marketing endeavors proves to be challenging, evaluators can learn from previous campaigns and identify which facets of social marketing events, programs and campaigns need to be improved. Additionally, by analyzing social movements and evaluating how they connect to social marketing, we can gain a clearer view on ways to ameliorate the field of social marketing. As social marketing becomes increasingly sophisticated and similar to commercial marketing, there is hope that social marketing can yield higher rates of success in the future. Friend and Levy (2002) claimed that it was nearly impossible to compare social marketing endeavors using quantitative criteria and advocate the use of qualitative methods. However, if social marketing scholars developed a more systematic paradigm to assess events, programs and campaigns employing a combination of both quantitative and qualitative methods, then it would be easier to establish which social marketing efforts generated more success than others. When there are too many confounding variables, conclusions cannot always be drawn and evaluations may not be viewed as legitimate. As a result, critics become skeptical of social marketing’s value and both the importance and credibility of social marketing decline. With the establishment of proper criteria and evaluation methods, social marketing can progress and initiate more social change.

Mudanças no hábito de fumar e ganho de peso gestacional : um estudo de coorte em capitais brasileiras

Objetivo: Avaliar a influência de mudanças no hábito de fumar sobre o ganho de peso gravídico materno. Métodos: Foram entrevistadas 5.564 gestantes com 20 anos ou mais, sem diabetes mellitus prévio em serviços de pré-natal geral de seis capitais brasileiras, entre 1991 e 1995, e acompanhamos, através de revisão de prontuários, as gestações até o parto, identificando 4.000 gestantes com peso pré-gravídico relatado, peso medido no terceiro trimestre, hábito de fumar e época de sua eventual modificação, quando disponíveis. Resultados: Entre as gestantes ex-fumantes (915, 23% do total), 240 (26%) pararam de fumar durante a gravidez. A mediana de cigarros/dia das que continuaram fumantes (717, 18%) foi reduzida de 10 para 5 após o início da gravidez. Após ajustar para idade, escolaridade, cor da pele, IMC pré-gravídico, paridade e centro clínico, as ex-fumantes ganharam 1.030 g (IC95% 590 a 1.460) a mais que as nunca fumantes, sendo maior a diferença (1.540, IC95% 780 a 2.300 g) nas que pararam após a concepção. O ganho do peso na gravidez se correlacionou, tanto em fumantes quanto em ex-fumantes, com o número de cigarros diminuídos na gravidez. Conclusão: Diminuir ou parar de fumar na gravidez, embora importante para uma gestação saudável, é fator de risco para ganho de peso materno.

An analysis of quit and dismissal determinants between 1988 and 1999 using the bivariate probit model

Excessive labor turnover may be considered, to a great extent, an undesirable feature of a given economy. This follows from considerations such as underinvestment in human capital by firms. Understanding the determinants and the evolution of turnover in a particular labor market is therefore of paramount importance, including policy considerations. The present paper proposes an econometric analysis of turnover in the Brazilian labor market, based on a partial observability bivariate probit model. This model considers the interdependence of decisions taken by workers and firms, helping to elucidate the causes that lead each of them to end an employment relationship. The Employment and Unemployment Survey (PED) conducted by the State System of Data Analysis (SEADE) and by the Inter-Union Department of Statistics and Socioeconomic Studies (DIEESE) provides data at the individual worker level, allowing for the estimation of the joint probabilities of decisions to quit or stay on the job on the worker’s side, and to maintain or fire the employee on the firm’s side, during a given time period. The estimated parameters relate these estimated probabilities to the characteristics of workers, job contracts, and to the potential macroeconomic determinants in different time periods. The results confirm the theoretical prediction that the probability of termination of an employment relationship tends to be smaller as the worker acquires specific skills. The results also show that the establishment of a formal employment relationship reduces the probability of a quit decision by the worker, and also the firm’s firing decision in non-industrial sectors. With regard to the evolution of quit probability over time, the results show that an increase in the unemployment rate inhibits quitting, although this tends to wane as the unemployment rate rises.
