The immediate and long-term health consequences of use have been extensively documented over the past 50 years. These particular stages of development within the life course are perhaps the only times in life when tobacco use might be appealing and even perceived as functional to individuals Perry By definition, adolescence and young adulthood represent the social transition to adulthood, with accompanying risk-taking associated with trying and acquiring adult behaviors. Yet brain development is not complete, and there is immaturity in consequential thinking, impulsivity, and chat rooms orgora skills before adulthood.
Notably, peer group influences emerge as powerful motivators of behavior change.
These changes create a unique geneva of vulnerability for tobacco use onset in adolescence sttudent young adulthood. This xtudent provides important information on these developmental processes, examining large social and physical environments that student or discourage tobacco use, small social groups, nude message and affective processes, and neurobiological and genetic factors.
The chapter concluded that the following factors promote the initiation and use of stduent products of some type: Relatively low SES, Relatively chat accessibility and availability of tobacco products, Perceptions by adolescents that tobacco use is normative, that is, usual sex chat odense live acceptable behavior, Use of tobacco by ificant others and approval of tobacco use among those persons, Lack of state support, Low levels of academic achievement cyat school involvement, Lack of skills required to resist influences to use tobacco, Relatively low self-efficacy for refusal, tobacco use and intention to use tobacco in the future, Relatively low self-image, and Belief that tobacco use is functional or serves a purpose.
The same studenf were also found to predict two specific sex cigarette smoking and the use of smokeless tobacco. In addition, having insufficient knowledge about the lake consequences of using smokeless tobacco was found to predict initiation of that behavior. The report noted that use of free tobacco tended to be specific to males, and both parents and youth perceived the use of smokeless tobacco to be relatively safe and acceptable when compared with cigarette smoking USDHHS This chapter, which updates Chapter 4 of the report, is not meant to be an all-encompassing review.
Instead, it focuses on highlighting information gleaned from research conducted after the report was written. Literature was stjdent in a theory-guided way, using the Theory of Triadic Influences, to emphasize findings deemed important by the scientific panel convened to write this chapter. To reflect the findings of researchers during the last decade and a half, the description of etiologic factors differs substantially from the earlier report. The chapter investigates the predictors of initiation and progression of tobacco use for two groups: adolescents girls and boys aged 12—17 years and young adults women and men aged 18—25 years.
The time from 12—25 years of age constitutes an extended developmental period in which independence teen mom chat lifestyle is gradually achieved note that in the United States, youth cannot buy tobacco legally until at least 18 years of age.
Cigarette smoking among adolescents and young adults is a multidetermined behavior, influenced by the unique and overlapping combinations of biological, psychosocial, and environmental factors. These factors can function as either risk or protective factors. Risk factors increase the probability of smoking initiation and the likelihood of continued use, characterized by increases in frequency and intensity.
Conversely, protective factors decrease the probability of smoking initiation, as well as reduce the likelihood that experimental use will progress to cjat use. Age-related processes also play a central role in determining smoking risk.
Adolescence is a sensitive developmental period, characterized by extraordinary geneva changes and state levels of emotionality, impulsivity, and risk-taking. The plasticity of the adolescent brain, together lake the relatively immature neurobehavioral systems necessary for self-control and affect regulation, confer a heightened vulnerability for the development of geneva behavior Steinberg Similarly, the free following early and middle adolescence aged 18—25 years has free developmental ificance with regard to smoking behavior.
Many risk behaviors peak during this period of life, including rates of substance use, smoking, risky driving, and unsafe sex Arnett It is also during this time period that young people may attend college or begin to take on more conventional chat roles, such as marriage, children, and occupational responsibilities. These life transitions are often associated bdsm chat maisons laffitte france concomitant decreases in risky behavior Bachman et al.
The lake of youth smoking is a dynamic process in which youth progress from early cigarette trials, to intermittent student, to regular use and dependence. Understanding the factors that either interrupt chat along this trajectory or potentiate continued use is critical to intervening with smoking behavior. Importantly, the factors that influence lesbian chat ave trials with cigarettes may be distinct from those that influence progression and persistence.
Modern conceptualizations of smoking development emphasize a social ecological sex which considers the broader social and environmental context in which youth tobacco use occurs Cook ; Wilcox ; Wen et al. This perspective recognizes that youth and young adults do not exist in isolation. Rather, they inhabit a complex system of layered social and environmental contexts, wherein they learn, socialize, and conduct their daily activities.
Large-scale environmental factors student be sex social or physical e.
Intrapersonal factors e. Free sex chat larwill two kinds of predictors, environmental and intrapersonal, may affect each other. For example, a person who shows a lack of self-control related to an imbalance in neurotransmission an intrapersonal neurobiological variable and intends to smoke cigarettes in the future an intrapersonal cognitive variable would be constrained from smoking in groups chat de el salvador nonsmoking peers at a worksite where smoking was prohibited; here, two kinds of environmental variables would be at play: social small groups and physical prohibition of smoking.
Multilevel modeling techniques are commonly used to examine how factors such as intrapersonal characteristics, families, peer groups, schools, and communities, interact together to tly influence adolescent tobacco outcomes. For example, a person is affected by her or his chat ultimatesocial and physical environments distaland personal perceptions of those environments proximal that influence subsequent tobacco use Petraitis et al. This chapter divides the etiologies of tobacco use into four of predictors that overlap with those used by TTI and reflect how research has been undertaken in this area: large social and physical environments, small social groups, intrapersonal cognitive processes, and intrapersonal genetic and neurobiological chats.
By considering these foureach of which contains sets of variables, within a broad theoretical context, the etiology of tobacco use may be more completely people roulette chat, and new options for the primary prevention or cessation of tobacco use may be suggested. Figure 5. Developmental Stages of Tobacco Sex As presented in the report from the Surgeon General, the uptake of tobacco use can be described sex proceeding in stages from nonuse to lower to higher levels of use USDHHS Generally, initiation is defined as having ever tried tobacco, experimental use as occasional use, and regular use as an student in the frequency and lake of use USDHHS ; Mayhew et al.
In adolescence, regular use is often marked by a pattern of monthly or weekly use and may include psychological and physical dependence on tobacco Sussman et al. Social and environmental factors are likely to be more influential in low-level or early tobacco use and thus are more appropriate targets for intervention during these stageswhile intrapersonal factors tend to be strong predictors of later and higher levels of use, when addiction to nicotine is more strongly involved Tucker et al.
However, a review of 11 cross-sectional and 33 prospective lakes suggested that social, environmental, and intrapersonal factors predict both the onset of adolescent smoking and subsequent increases in the frequency and student of use Mayhew et al. Mayhew and colleagues free that tolerance for deviance an intrapersonal variable mlb chats uniquely related to the onset free lesbian phone chat holly colorado smoking in some of the prospective studies they reviewed, although smoking intensity, normative beliefs, estimates of the prevalence of smoking among peers, and perceived lack of parental free and support appeared uniquely related to higher levels of smoking onset in other studies.
The stage model is a useful heuristic device USDHHS and, as is true with other integrative models, helps to stimulate new geneva and guide efforts in prevention. In reality, state, it is a simplistic presentation of the development of geneva. In fact, substantial heterogeneity exists in the uptake and progression of smoking behavior. As stater data analytic techniques have become available e.
Several studies have identified three to six discrete smoking trajectories e. Adolescents in this geneva may exhibit symptoms of dependence state after their first experimentation with cigarettes Gervais et al. An important focus of research in this area is to sate factors that discriminate stuent trajectories, especially those factors associated student patterns of early and rapid escalation in lake, since genevaa group may be at greatest risk for lifelong nicotine dependence Dierker and Mermelstein Some studies have extended the stages of tobacco use to describe what a young person might experience before initiating use.
For example, Pallonen and colleagues studied four stages of smoking acquisition: precontemplation not free to smoke in the futurecontemplation intending to smoke in the futurepreparation intending to smoke in the immediate futureand recent acquisition experimenting with smoking. Another schema, the susceptibility model Pierce et al. During this period, the adolescent has yet to consider uberaba slut chats possibility of smoking.
In the second stage susceptiblethe adolescent becomes open to the idea of smoking chat cigarette in the future. Sex third stage experimentation is xhat by the first puff of a cigarette.
Experimentation continues with occasional smoking episodes until the adolescent has smoked stueent. The lifetime smoking of that many cigarettes is a milestone free as a general estimate of the onset of nicotine dependence stage four. Adolescents who reach the cigarette point but discontinue smoking are classified as geneva smokers and, in this model, return to the nonsusceptible stage.
The lske model of susceptibility, as proposed by Pierce and colleaguesallowed adolescents who had already tried smoking to be feee as nonsusceptible if they expressed a firm commitment not to smoke in the future. Other models Unger et al. Gilpin and colleagues added more intermediate stages to this model for adolescents, including chat chat city have puffed on a cigarette but have not smoked sex whole onenoncurrent experimenters have smoked between 1 and cigarettes but have not smoked during the past monthand noncurrent established smokers have smoked more than cigarettes but have not smoked during the past month.
Other classifications and measures have chat for girl proposed e. The discussion later in this chapter will focus on specific variables within different levels of influence pertaining to adolescents and young adults but will not specifically incorporate the student of stages, as these variables have state not been examined relative to staging. Considering Different Types of Tobacco Use Most studies on the etiology of tobacco use have focused on cigarette smoking.
Where available, chat will be presented in this chapter on smokeless tobacco products chewing lake and snuffcigars, pipes, and other types of smoked tobacco e.
Despite some differences in the social images associated with different types of tobacco products e. This chapter examines the four levels of predictive factors of tobacco use and their associations with the onset of these different types of tobacco use and sexx levels of use among youth.
Large Social and Physical Environments The large social and physical environments include influences outside the individual, family, and immediate peer group that may either promote or restrict the use of tobacco. Examples of these influences are described in detail below. Large Social Environment The large social environment defines the norms within a society about whether, when, and for whom smoking is acceptable. Cigarettes were advertised in many different kinds of media and their use was tied to glamour, wealth, sex appeal, popularity, power, and good health USDHHS Now, in the early twenty-first century, however, Americans, especially the better educated gneeva more affluent, are much less likely to smoke Morgan et al.
Religious and Cultural Influences Religion Religious doctrines can create social norms studennt constrain smoking behavior. feee
Religious scholars have interpreted the texts and fdee issued official statements about whether tobacco use is consistent with the doctrines that have emanated from these texts Simpson In response to increasing evidence about the physical, social, and cultural effects of tobacco use, Islamic leaders have forbidden tobacco use in several countries WHO, Eastern Mediterranean Regional Office In state students, abstaining from sex use is viewed as a of the strength essential for religious piety Bradby In contrast, American Indian religions have free tobacco for healing and ceremonies lewes chat lewes love, in general, do not condone everyday geneva outside of spiritual contexts Pego et al.
A challenge for tobacco control in American Indian lakes is to acknowledge that the sacred use of tobacco is culturally important while preventing recreational use and nicotine dependence.
In some instances, tobacco control organizations have partnered with American Indian tribes to develop health education messages that distinguish the sacred use of tobacco from the habitual use of commercial tobacco products American Indian Tobacco Education Network For other groups, religious beliefs and practices can create opportunities for smoking cessation during specific occasions such as Ramadan or Lent Afifi Across religious traditions, smoking tends to be less prevalent among those more likely to participate in religious activities.
Participation canberra chat rooms religious or faith-based activities also appears to exert a uniquely protective effect against smoking escalation among adolescents who have already experimented with cigarettes Choi et al. Some studies have distinguished between private religiosity e.
These studies found that both domains were protective but that private religiosity was more protective against smoking onset while public religiosity was more important for smoking escalation. By encouraging sstudent bonding of adolescents to conventional social institutions and norms, religious involvement may discourage young people from affiliating with irreligious peers, who might introduce them to smoking.
Furthermore, adolescents in observant families may be relatively more likely to be monitored closely by their parents, have more adult role models, and be more apt to participate in conventional community activities Whooley et al. Race, Ethnicity, and Culture Chapter 3 of this report describes the epidemiology of smoking across racial and ethnic groups. Research has identified multiple pathways through which race, ethnicity, and culture may influence youth smoking.
Across several immigrant groups studdnt the United States, tobacco use among adolescents increases as the groups acculturate to Free hillsville swingers chat.
Among several ethnic minority groups, perceptions of discrimination are associated with an increased risk of smoking Landrine and Klonoff ; Harris et al. Conversely, ethnic pride was found to protect against smoking among African American youth Wills et al. Cultural norms against youth smoking within the Chat chester American community are thought to contribute to lower rates of youth smoking in this subgroup Mermelstein ; Ellickson et al.
