Social, personality and environmental determinants of smoking in young Finnish men

The study was based on 471 males, aged 19 to 20 years, who started their compulsory military service in three military bases in Southwest, Southeast and Northern Finland in February 1982. Of these subjects 48% smoked regularly and had smoked in the past three weeks. The correlation between the reported number of cigarettes smoked a day and serum thiocyanate was 0.60. Seventy-four per cent of the subjects whose best friend smoked, were current smokers compared with 24% of the others. Proportion of smokers was higher in urban areas than in rural areas. Among the 14 explanatory variables in the multivariate logistic analysis, family members' and friends' smoking, the place of residence, strenuousness of leisure-time physical activities, number of friends, rebelliousness, intelligence test score, and general pessimism were most strongly associated with the likelihood of being a current smoker. The model explained 87% of the smoking variance.     

Peers, schools, and adolescent cigarette smoking.

PURPOSE: To investigate the effects of popularity, best friend smoking, and cigarette smoking within the peer networks on current smoking of seventh- through 12th-grade students. These factors were examined for adolescents attending schools with varying rates of student cigarette smoking. METHODS: This study used data from the saturated school sample of National Longitudinal Study of Adolescent Health (Add Health), a nationally representative school-based sample. The sample for the present study was 2525 adolescents in Grades 7-12 who completed an in-school questionnaire and an in-home interview. Information from the in-school questionnaire was used to construct measures of school smoking prevalence and popularity. Using peer nominations from the in-home interview, best friend smoking, and peer network smoking exposure were constructed using the peers' own reports of their cigarette smoking. Multiple regression techniques were used to estimate the risk of current cigarette smoking as a function of popularity, best friend smoking, peer network smoking, and school smoking prevalence, and all first-order interactions between measures of peer and school smoking prevalence. RESULTS: Adjusting for age, gender, race/ethnicity, parent education, school, and availability of cigarettes in the home, the risk of current smoking was significantly associated with peer networks in which at least half of the members smoked [odds ratio (OR) = 1.91], one or two best friends smoked (OR = 2.00), and with increasing rates of school smoking prevalence (OR = 1.73). In addition, there was a significant interaction of popularity and school smoking prevalence such that risk of current smoking was somewhat greater among popular students in schools with high smoking prevalence than among popular students in schools with low smoking prevalence. CONCLUSION: Findings suggest that school environments are important contexts for understanding peer group influences on adolescent cigarette smoking.     

Predicting the onset of smoking in boys and girls

The problem of the high prevalence of smoking among girls and young women is of great concern. In an attempt to identify the factors which influence girls and boys respectively to attempt smoking, the study examines social background, advertising and brand awareness, knowledge, teaching and personal beliefs in conjunction as predictors of smoking. In this study which involved the administration of identical pre- and post-test questionnaires to a sample of boys and girls aged 12 and 13 years, nine variables expressed by never-smokers at pre-test stage were assessed as predictors of immediate future smoking. The two tests were administered 4 months apart to 1125 boys and 1213 girls in northern England. The nine variables included were parental smoking, best friends' smoking, perceived positive values of smoking, perceived negative values of smoking, correct health knowledge, cigarette-brand awareness, having a favourite cigarette advertisement, having a cigarette-brand sponsored sport in four top favourites on television. One group received teaching about smoking between the pre- and post-tests and this was also included as a variable. For boys, no variable investigated had any consistently statistically significant correlation with the uptake of smoking. The most important predictor of smoking for boys, having a best friend who smoked, was significant on application of the chi 2 test (P 0.037), although it was non-significant when included singly in a logistic regression model (0.094); the discrepancy was probably due to the small number of best friends known to smoke. For girls, four variables were found to be significant predictors of smoking when included singly in a logistic regression.(ABSTRACT TRUNCATED AT 250 WORDS)     

Depressive mood, the single-parent home, and adolescent cigarette smoking.

The association between depressive mood and cigarette smoking among adolescents was examined within a multivariate model. Subjects were 205 eleventh graders (123 boys and 82 girls) enrolled in a Northeast metropolitan public high school for science-oriented students. Logistic regression analysis showed an independent relation of depressive mood, friends' smoking behavior, and living in a single-parent home with cigarette smoking. Depression scores correlated with the number of cigarettes smoked. These associations suggest that depressive mood and stress may contribute to the onset of smoking.     

Cigarette smoking and its risk factors among elementary school students in Beijing.

OBJECTIVES. This study investigated patterns of and risk factors for smoking among elementary school children in Beijing, China. METHODS. In 1988, anonymous questionnaires were administered to a multistage stratified cluster sample of 16996 students, aged mostly 10 to 12, in 479 fourth- to sixth-grade classes from 122 Beijing elementary schools. RESULTS. Approximately 28% of boys and 3% of girls had smoked cigarettes. The most frequently cited reasons for smoking initiation were "to imitate others'' behavior" and "to see what it was like." Girls were more likely to get cigarettes from home than to purchase their own. Having close friends who smoked and being encouraged by close friends to smoke were strong risk factors for smoking. Smoking was also associated with lower parental socioeconomic status; having parents, siblings, or teachers who smoked; buying cigarettes for parents; performing poorly in school; and not believing that smoking is harmful to health. CONCLUSIONS. Gender differences in smoking prevalence among adolescents in China are larger than those among US teenagers, whereas the proximal risk factors for smoking are similar. Major efforts are needed to monitor and prevent smoking initiation among Chinese adolescents, particularly girls.     

Children's exposure to smoking.

Exposure to smoking and the attitudes of other people have, in many studies, been associated with an increase in smoking through childhood and adolescence. Previous studies which have examined the relative influence of parents, siblings and friends on young people smoking do not show the same pattern of results, indicating that parents and siblings who smoke may or may not have an influence above or beyond that of friends. In this study, the extent to which these sources of exposure influence young people is examined. A related hypothesis which is tested in this study is that the amount of exposure to smoking may be a factor which influences young people to smoke independent of the particular source of the influence. The pattern of results suggests that the source of the influence is more important than the extent of influence among friends and family members. In particular, the influence of friends' smoking was evident at ages 9 to 15 years to the exclusion of the parental example of smoking. Parental smokers may lead their children to try smoking but it seems unlikely that this is related to them smoking at a later age. While peer influence may result in smoking, the influence of parents or older people smoking may be becoming a disincentive in this time of changing attitudes to smoking.

目的了解农村中学生的吸烟情况及其影响因素。方法通过分层整群抽样的方法，在合肥市郊区随机抽取4384名初中和高中二年级学生进行问卷调查，并采用Logistic回归模型进行相关因素分析。结果总吸烟率为29．0％，不同性别及不同年级学生之间差异均有统计学意义。Logistic回归分析提示，能正确认识吸烟对青少年的危害、认为吸烟是不良习惯、坚信自己永远不吸烟等因素可能防止学生吸烟行为的发生；而男性、高年级、认为男性吸烟有风度及有利于社交、将吸烟作为空闲消遣、朋友吸烟、父亲吸烟、老师在课堂上吸烟等则是诱发学生吸烟的重要危险因素。结论学生控烟应从家庭、学校、社会，生理与心理因素等多方面采取综合的干预措施。     

Social environmental and individual factors associated with smoking among a panel of adolescent girls

This study assessed changes in the influence of social environmental and individual factors-and the interaction of these factors with time-on smoking prevalence for girls. Longitudinal panel surveys of adolescent girls (N = 921 in both 2000 and 2004) from schools in Louisiana were completed in the ninth grade (2000) and then again in the twelfth grade (2004). A fixed effects hierarchical multiple regression model assessed the relation of changes in social environmental and individual factors to smoking prevalence. Increases in smoking prevalence over time among adolescent girls were associated with their perceptions of themselves as overweight and perceiving low risk associated with smoking. Increases in smoking prevalence over time were also associated with having friends who smoked, perceptions of friends' approval of smoking, having family members who smoked, and having monetary discretionary spending. Having friends who smoked was more strongly associated with smoking in the twelfth grade than in the ninth grade. While more black adolescent girls smoked than did white girls in the ninth grade, by the twelfth grade, more white adolescents girls smoked than did black girls. Interventions that target adolescent girls should consider the temporal variability of individual and social environmental factors.     

Dynamics of adolescent friendship networks and smoking behavior: Social network analyses in six European countries

The co-evolution of adolescents' friendship networks and their smoking behavior is examined in a large sample across six European countries. Selection and influence processes are disentangled using new methods of social network analysis that enable alternative selection mechanisms to be controlled for. The sample consisted of 7704 adolescents participating in the control group of the ESFA (European Smoking prevention Framework Approach) study. The design was longitudinal with four observations. The main measurements were friendship ties, adolescents smoking behavior, parental smoking behavior, and sibling smoking behavior. Results indicated that in each country adolescents preferred selecting friends based on similar smoking behavior. Support for the influence of friends was found in only two countries. A similarity in smoking behavior between friends was explained more strongly by smoking-based selection processes than by the influence of friends in each of the six countries. Prevention programs need to address aspects that drive peer selection, and reinforce non-smoking attitudes in adolescents.     

Relationship between Adolescents' and Their Friends' Eating Behaviors: Breakfast,Fruit, Vegetable,Whole-Grain,and Dairy Intake

We examined associations between adolescents' and their friends' healthy eating behaviors, specifically breakfast, fruit, vegetable, whole-grain, and dairy food intake as reported by both adolescents and their friends. Data for this study were drawn from EAT-2010 (Eating and Activity among Teens), a population-based study examining multilevel factors of eating, physical activity, and weight-related outcomes among adolescents (80% racial/ethnic minority) in Minneapolis/St Paul, MN, during the 2009-2010 academic year. In-class surveys were completed by 2,043 adolescents in 20 schools. Adolescents identified friends from a class roster; friends' survey data were then linked to each participant. Generalized estimating equation linear regression models were used to examine associations between adolescents' healthy eating behaviors and these behaviors from their friends (friend group and best friends), adjusting for sociodemographic characteristics. Significant positive associations were found for breakfast eating between adolescents and their friend groups and best friends (friend groups β=.26, P<0.001; best friends β=.19, P=0.004), as well was for whole-grain intake (friend groups β=.14, P<0.001; best friends β=.13, P=0.003) and dairy food intake (friend groups β=.08, P=0.014; best friends β=.09, P=0.002). Adolescents' and their best friends' vegetable intake were also significantly related (β=.09, P=0.038). No associations were seen among friends for fruit intake. Findings from our study suggest that adolescent friends exhibit similarities in healthy eating patterns. Registered dietitians and health professionals may consider developing strategies to engage friends to promote adolescents' healthy dietary behaviors.     

Communication about smoking in Dutch families: associations between anti-smoking socialization and adolescent smoking-related cognitions

Parents play an important role in the development of young people's smoking behavior, through the modeling effects of their own smoking status, through the ways they raise their children and through the ways they deal with smoking at home. The present study focused on anti-smoking socialization by, first, comparing the perspectives of both parents and an adolescent on eight indicators of anti-smoking socialization. In addition, we aimed to examine how these indicators of anti-smoking socialization are related to adolescent smoking-related cognitions (e.g. attitudes, self-efficacy, intentions to smoke). Data were collected from 116 Dutch families with fathers, mothers and adolescents (10-19 years old) included. Self-reports of these family members were used by means of questionnaires that were sent through the Internet. The findings showed that parents and adolescents differ in their reports on anti-smoking socialization. In general, mothers are more positive about anti-smoking socialization than adolescents and fathers. Furthermore, the results demonstrate that aspects of anti-smoking socialization, such as parental monitoring, norms on adolescents smoking and reactions on adolescent smoking, are related to smoking-related cognitions, such as negative attitudes to smoking, lower intentions to start smoking and higher self-efficacy. These findings are a first step in research on smoking-specific socialization that is considered to be of importance for the development of effective smoking prevention programmes focusing on parents. Nonetheless, longitudinal studies on large samples of families are needed to replicate the findings in this study.     

Lifetime parental smoking history and cessation and early adolescent smoking behavior

BACKGROUND: Associations are examined between parental smoking and smoking onset by their children. Smoking parents are more likely to have children who start smoking in their teenage years; however, less is known about whether parental quitting is related to adolescent smoking. METHODS: A cross-sectional national sample of 2,206 adolescents, ages 10-14 years, living in two-parent households were interviewed for the DEFACTO annual report on Dutch youth smoking behavior. Adolescent smokers reported that they have tried smoking, even one puff. Respondents indicated whether their parents were never, former, or current smokers, and provided, in the case a parent had quit, their age at that time. RESULTS: Logistic regression analyses revealed that likelihood increased gradually: adolescents with both parents being current smokers were four times more likely to be a smoker compared to adolescents with parents who had never smoked. Additionally, within the group of adolescents whose parents quit smoking, the findings demonstrated that the earlier the parents stopped smoking in the life of their offspring, the less likely their children were to start smoking in adolescence. CONCLUSIONS: Parental smoking history is associated with smoking initiation in early adolescence. Parental cessation at an early age of their offspring reduces the likelihood of adolescent smoking initiation. Preventive efforts, therefore, should focus on the benefits of parental cessation as early as possible.     

Smoking in young adolescents: an approach with multilevel discrete choice models

STUDY OBJECTIVE: To understand the context for tobacco smoking in young adolescents, estimating the effects of individual, family, social, and school related factors. DESIGN: Cross sectional analysis performed by multilevel logistic regression with pupils at the first level and schools at the second level. The data came from a stratified sample of students surveyed on their own, their families' and their friends' smoking habits, their schools, and their awareness of cigarette prices and advertising. SETTING: The study was performed in the Island of Gran Canaria, Spain. PARTICIPANTS: 1877 students from 30 secondary schools in spring of 2000 (model's effective sample sizes 1697 and 1738). MAIN RESULTS: 14.2% of the young teenagers surveyed use tobacco, almost half of them (6.3% of the total surveyed) on a daily basis. According to the ordered logistic regression model, to have a smoker as the best friend increases significantly the probability of smoking (odds ratio: 6.96, 95% confidence intervals (CI) (4.93 to 9.84), and the same stands for one smoker living at home compared with a smoking free home (odds ratio: 2.03, 95% CI 1.22 to 3.36). Girls smoke more (odds ratio: 1.85, 95% CI 1.33 to 2.59). Experience with alcohol, and lack of interest in studies are also significant factors affecting smoking. Multilevel models of logistic regression showed that factors related to the school affect the smoking behaviour of young teenagers. More specifically, whether a school complies with antismoking rules or not is the main factor to predict smoking prevalence in schools. The remainder of the differences can be attributed to individual and family characteristics, tobacco consumption by parents or other close relatives, and peer group. CONCLUSIONS: A great deal of the individual differences in smoking are explained by factors at the school level, therefore the context is very relevant in this case. The most relevant predictors for smoking in young adolescents include some factors related to the schools they attend. One variable stood out in accounting for the school to school differences: how well they enforced the no smoking rule. Therefore we can prevent or delay tobacco smoking in adolescents not only by publicising health risks, but also by better enforcing no smoking rules in schools.     

A survey on smoking habits and attitudes among adolescents in Greece

The objective of the present study was to investigate smoking habits among 699 secondary school students, along with their attitudes toward smoking and their perceptions on the consequences of tobacco use in their health. Our results indicate that Greek adolescents begin to smoke mainly due to curiosity and for stress reasons. Furthermore, having friends who smoke is highly associated with smoking and intention for smoking. Likewise, paternal smoking seems to reinforce students' intention for smoking. On the contrary, parental disapproval of smoking leads to anti-smoking behavior. Adolescents' attitudes toward smoking are also related to a series of similar factors such as parental educational status, parental smoking, and parental disapproval of smoking, friends who smoke, and, finally, adolescents' age, smoking behavior, and intention for smoking. The impact of tobacco use in human health seems to be understood better by older students. All these factors must be taken into account for a successful implementation of an anti-smoking intervention program.     

The Role of Friendship in the Lives of Male and Female Adolescents: Does Diabetes Make a Difference?

PurposeWe examined differences in the nature of friendship between adolescents with diabetes and healthy adolescents. We also examined whether friend support and negative relations with friends were related to health for both groups.MethodWe interviewed 127 adolescents with diabetes and 129 healthy adolescents on two occasions, separated by one year. We measured aspects of friendship and psychological health among both groups as well as self-care behavior and metabolic control among adolescents with diabetes. We used logistic regression analysis to predict the presence of friends, repeated measures analysis of covariance to predict changes in friendship over time, and hierarchical multiple regression analysis to examine the relations of friendship to psychological health, self-care behavior, and metabolic control.ResultsBoth groups of adolescents were equally likely to have a best friend and boyfriend/girlfriend, but healthy adolescents were more likely to have an other-gender friend. Adolescents with diabetes and healthy adolescents reported similar levels of friend support, but support increased over the year for healthy girls only. Boys with diabetes had the lowest levels of friend support. Negative relations with friends were inversely related to psychological health and predicted a decline in psychological health over time. Negative relations also predicted poor metabolic control and a deterioration of metabolic control over time.ConclusionThere are similarities and differences in the nature of friendship for adolescents with diabetes compared with healthy adolescents. Friendship serves a protective function for psychological health for both groups and has implications for physical health among those with diabetes.

Parental influences predict adolescent smoking in the United States, 1989–1993

Purpose: To examine parental influences on two transitions in the adolescent smoking uptake process: from never having smoked to experimentation and from experimentation to established smoking.

Methods: Using data from the longitudinal Teenage Attitudes and Practices Survey of 1989-1993, we related perceived parental concern about their adolescents' future smoking, parental smoking status, problem-solving communication between parent and adolescent, demographics, and other factors at baseline to experimentation by follow-up among those who had never puffed on a cigarette (n = 4149). We also related these factors at baseline to reaching a lifetime level of smoking of at least 100 cigarettes by follow up among those who had experimented but smoked <100 cigarettes (n = 2684) in univariate and multivariate analyses.

Results: Among never-smokers, baseline susceptibility to smoking and having male best friends who smoke predicted experimentation in the next 4 years. Among experimenters, susceptibility to smoking, having male or female best friends who smoked, and lack of parental concern about future smoking distinguished those who progressed to established smoking by follow-up. Furthermore, communicating with parents first about serious problems was protective against progression from experimentation to established smoking.

Conclusion: Interventions aimed at reducing adolescent smoking should encourage cessation for parents who smoke and help parents communicate strong anti-smoking norms to children and adolescents and maintain strong lines of communication with them.     

Predictors of smoking stage transitions for adolescent boys and girls

BACKGROUND: Aim of this study was to identify predictors of transition from never smoking to smoking monthly or more often in a European sample of adolescents. To show whether predictors differed between genders, analyses were run for boys and girls separately. METHODS: From six European countries, 4055 never smokers participated at baseline (1998). One year later, respondents were asked to indicate their smoking status. Respondents were categorized as smoker (smoking monthly or more) or non-smoker (smoking less than monthly). The predictive qualities of predisposing, motivational and intentional concepts were assessed using logistic regression analyses. RESULTS: Girls were more likely to be a smoker at follow-up. More spending money, modeling from parents and a higher intention to start smoking were predictive of smoking uptake in both genders. Boys were more likely to start smoking when perceiving less cons of smoking, drinking more alcohol and perceiving a social norm towards not smoking from parents. Girls experiencing higher social pressure to smoke from friends were more likely to start smoking. CONCLUSIONS: Separate uptake prevention interventions for boys and girls do not seem warranted. Boys may benefit from a program also addressing other deviant behaviors. Girls should continue to be supplied with specific skills to resist social pressure.     

Do friendships change behaviors, or do behaviors change friendships? Examining paths of influence in young adolescents' alcohol use.

PURPOSE: This study examined support for models of peer influence, which postulates that young adolescents whose friends use alcohol will also engage in that behavior, and of peer selection, whereby young adolescents seek out friends whose drinking behavior is similar to their own. METHODS: Data for this study are from 1804 adolescents participating in Project Northland, a school- and community-based alcohol use prevention trial. Using latent variable structural equation modeling, a series of models examined directions of influence between participant alcohol use and friend drug use over three points in Grades 7, 8, and 9. RESULTS: Findings indicated that higher levels of friends' drug use led to increased participant alcohol use. The reverse-order relationship (i.e., greater participant involvement in alcohol leading to more drug use among friends) was not supported by these data. Finally, best-fitting models supported the notion that both participants' alcohol use and the alcohol and other drug use of friends were highly stable over time. CONCLUSIONS: Similarity in drinking behavior among adolescent friends may be more related to processes of peer influence than to processes of peer selection. Findings support the utility of alcohol use prevention programs that equip younger teens with skills to resist peer influences to use alcohol.
