Estimated Time for Occurrence of Smoking-Related Consequences among Pregnant and Non-Pregnant Bulgarian Women
– Reported, January 16, 2012
Methods:
Over a two-week period, eighty women, selected to constitute four subgroups formed by pregnant vs. non-pregnant and trying vs. not trying to quit smoking, rated times at which they would expect smoking-related consequences to occur given continuing or quitting smoking.
Results:
Somatic health consequences were estimated to occur later than consequences related to mood and social relations. All consequences were estimated to occur later given quitting smoking. Pregnancy had an effect on the estimated time that consequences would occur, with pregnant women estimating earlier occurrence of consequences related to mood and social relations than non-pregnant women did.
Conclusion:
Health messages should stress consequences for somatic health in quitting smoking, since outcomes later in time might have too low a value to exert a positive effect on decisions to quit smoking.
Research over the years has clearly established both short- and long-term benefits for women who do not smoke during pregnancy. Smoking in early gestation and through pregnancy is associated with adverse pregnancy outcomes like preterm delivery, low birth weight and stillbirth .
In recent research time-related aspects of smoking have attracted increased interest, and the possibility of counseling especially tailored to the motivational stage of pregnant women has been explored . Stages of readiness for behavior change (i.e., quitting smoking) are identified in the form of five groups: relapsers, persons in the precontemplation stage, persons in the contemplation stage, actors and maintainers. Readiness has been found to vary with stages of change , and persons with a positive attitude towards smoking cessation more often intend to quit smoking .
In some respects, addictive behavior could be construed as a temporal preference in which the immediate pleasure of the addictive behavior is preferred to the cessation of the addictive behavior . There is a time-discounting effect in addictive behavior; that is, the value of future consequences diminishes as a function of temporal distance, an effect that represents the weight an individual places on the future relative to the present when she makes a decision that has future consequences . The situation could be described as a choice between the immediate pleasure of having a cigarette, and having good health or avoiding illnesses related to smoking in the remote future.
Impulsivity has been related to perceptions of positive and negative reinforcement from smoking , and it is supposed that those who value remote values less compared to those near in time are most impulsive . More impulsiveness has been associated with smoking, and in a study it was found that impulsiveness predicted postpartum relapse to cigarette smoking among pregnant women. Discount rates and impulsiveness have also been found to be higher for current smokers compared to never-before smokers .
The purpose of the present study was to examine judgments by pregnant and non-pregnant women who were intending either to quit or to continue smoking, about when they expected smoking-related consequences to occur given continuing or quitting smoking. Because failures in quitting have been attributed to a shortened time perspective, changes in perceived time of outcome for different consequences related to smoking were of interest. In studying time discounting and patterns of cigarette smoking, discount rates have generally been obtained by the discounting of monetary rewards .
In the present study pregnant and non-pregnant womens judgments of times at which smoking-related consequences would occur were studied over a span of fourteen days. Women who expressed an intention to quit smoking and women who did not intend to quit smoking were studied, thus constituting four subgroups defined by pregnancy/non-pregnancy and intent to quit/no intent to quit.
Forty pregnant women were contacted in family practices in Bulgaria when they were under ordinary medical observation during pregnancy. Their pregnancies were normal and uncomplicated. Forty non-pregnant women were recruited at the same clinics when they came for regular examinations. The women were asked whether they smoked. If they smoked they were asked about their intent to quit or not quit smoking. The women were given the question Do you intend to quit smoking? Yes was interpreted as an intention to quit. Of course, it could be argued that time does matter with regard to intent to quit. For example, it would be a difference between someone who was intending to quit in ‘the near future’ versus ‘someday’.
Depending on whether or not they intended to quit smoking, they were assigned to one of four groups. Each group consisted of twenty women: pregnant smokers who did not intend to quit smoking, pregnant smokers who intended to quit smoking, non-pregnant women who did not intend to quit smoking, and non-pregnant women who intended to quit smoking. Approval for the study was obtained from the institutional review board. No intervention was used to try to convince participating women not to smoke. All women agreed to participate in the study and gave informed consent in writing. The women received no compensation for participating.
In general, smoking-related consequences related to mood and social relations were estimated to occur sooner than pregnancy-related and somatic health consequences. The difference between estimated occurrence of somatic health consequences and consequences related to pregnancy was very small. All consequences were estimated to occur later given the condition of quitting smoking.
Pregnancy had an effect on the time at which the consequences were estimated to occur. Pregnant women estimated that consequences related to mood and social relations would occur earlier than nonpregnant women did; this was so both for the conditions of continuing to smoke and of quitting. The intent to quit showed an effect in womens estimates of when the somatic consequences of smoking would appear given the condition of continuing to smoke; it also showed in expected consequences for mood and social relations given the condition of quitting.
Intent to quit smoking was related to the number of earlier attempts to quit. This finding suggests that the women who are trying to quit smoking are generally more motivated to stop smoking than those who are not trying to stop. It indicates that success is preceded by a certain number of attempts to quit, and that the chance is improved by every attempt. The result is in accord with earlier results obtained by Pickett, Wakschlag, Dai and Leventhal , where a substantial proportion of the women studied exhibited a pattern of repeated cessation and relapse. However, in our study the number of participants was quite small with a small number of successful quitters. Many attempts to quit are unprepared ; this suggests that models of smoking cessation should place greater emphasis on the dynamic nature of motivation to quit.
Of course, there is an increased statistical probability of success, but there is also an increased psychological probability. In addition, non-pregnant women who were trying to quit and who had smoked for the longest period (8.7 years) also exhibited the highest number of previous attempts to quit (4.0). It is expected that the number of attempts is related to length of time smoking.
A new feature of the present design was that the women performed ratings at the start of the study and throughout the period of the study. The current design made it possible to obtain information about changes over time when processes that lead to success in quitting smoking or to relapse are being studied. In fact, a distinction must be made between anticipated waiting time and actual waiting time: the actual time that elapses between the present and a future event, positive or negative, is evidently more aversive.
Our data support the potentials of the new framework introduced in the present study in analyzing addictive behavior and in smoking cessation programs. The present results indicate that discounting could be expected to have the largest impact on somatic health consequences in that they were estimated to occur later . Smokers generally exhibit rapid loss of value for delayed health outcomes; this underscores the need for smoking-cessation treatments that provide relatively immediate consequences for abstinence.
Therefore, health messages should stress the outcome in somatic health consequences for quitting smoking, as effects later in time could have a low value and thereby a negative affect on decisions to quit smoking. Another factor that health messages should emphasize is that consequences on somatic health are more likely to be irreversible than effects on relationships.
For the two conditions of continuing to smoke and quitting smoking, there were only small changes over time, suggesting that this variable is independent of the passage of time. One possible explanation is that the judgments encompass a time span from this week to 13 months or later and in its extreme, never. The duration of the study, however, was only fourteen days.
Smoking is probably most salient in pregnant women because women who smoke during pregnancy subject themselves and their developing fetus and newborn to special risks. Although evidence indicates that individual smoking cessation counseling does not increase quitting rates during pregnancy, the method may have long-term effects . It is therefore important to identify variables which ensure that the initial attempts to quit are translated into long-term abstinence .
Smoking during pregnancy is a complex and variable behavior for many women, and brief smoking cessation interventions in early pregnancy are likely to be inadequate for many smokers during pregnancy. It has been suggested that differing predictors may contribute to understanding the different transitional stages of smoking cessation. Of course, the etiology for smoking like e.g., experiences of violence and stress may impact the findings.
Problems related to behavior change and its maintenance are a significant challenge to domains that deal with health-related behaviors, as professional health care services do. This applies to addictive habits like smoking; most cessation programs are generally effective only temporarily in helping people with their struggle against smoking .
The prevalence of smoking is high in Bulgaria , and results of the present study may be limited to countries with similar smoking habits. High prevalence of smoking has been found to be associated with a lower motivation to quit smoking, fewer attempts to quit and higher cigarette consumption among smokers . A recent study found that only 68% of smokers were asked about their smoking habits during pregnancy by their gynecologist, and that both smokers and non-smokers had insufficient information about the impact of smoking on their baby.
Conclusions
All women estimated that the condition of quitting smoking would make consequences occur later. Pregnant women estimated that consequences related to mood and social relations would occur earlier than non-pregnant women did. The period of pregnancy might provide a window of opportunity to promote smoking cessation and smoke-free families.
Further, the significance of the value of remote outcomes in explaining addictive behavior should be considered to a greater extent than it has been in the past, as it is evident that such behavior is not the result of one single action but a long series of actions that have been taken . The study illustrates the necessity of considering changes that occur over time when we are explaining health behavior. The present study encompassed two weeks, and future studies may benefit from studying a longer period of time.
