Cigarette smoking for weight loss or control among adolescents: gender and racial/ethnic differences.

PURPOSE: To describe gender and racial/ethnic differences in the prevalence of cigarette smoking for weight loss or control in an adolescent population-based sample, and relationships among heavy smoking, weight concerns and smoking to lose or control weight. METHODS: Anonymous questionnaires were administered to 81,247 9th and 12th grade public school students across the state of Minnesota in 1998. Variables of interest included smoking frequency, weight concerns, and smoking for weight loss or control. Logistic regression analyses were used to estimate the odds of smoking to lose or control weight by race/ethnicity and gender, and to evaluate the relationships between smoking to lose or control weight and heavy smoking, perceptions of overweight, and weight concerns by race/ethnicity and gender. RESULTS: With the exception of black females, female smokers of different racial/ethnic groups were as likely as white girls to smoke for weight loss or control. Compared to white male smokers, American Indian and Asian American male smokers were more likely to smoke for weight loss or control, and black, Hispanic, and mixed race male smokers were equally likely to smoke for weight loss or control. Heavy smokers, smokers who perceived themselves as overweight or were weight-concerned were significantly more likely to report smoking as a weight control method. CONCLUSIONS: Smoking for weight control is prevalent across many race/ethnic groups and both genders among adolescents.     

中国青少年与父母交流性相关话题的状况分析

目的:了解目前我国家庭性教育开展状况及存在的主要问题,为进一步发挥家庭在青少年性与生殖健康教育中的作用提供依据。方法:采用分阶段抽样,对全国6个省城市和农村地区的5709例不同类型的青少年进行计算机辅助的自填问卷调查,调查青少年与父母交流性话题的状况及存在的障碍,并分析其影响因素。结果:50%的被调查青少年与父母亲交流过性话题,交流的内容主要为男孩女孩适宜的举止、友情、爱情与婚姻及人体生理知识。不与父母交流性话题的最大原因是感到不好意思,相当比例是父母在面对性话题时敷衍了事、避而不答或没有能力回答。多因素分析显示青少年与父母的性别、父母的文化程度、家庭结构、家庭氛围等因素影响了亲子间性话题的交流。结论:青少年与父母交流性相关话题非常有限,父母的观念和能力阻碍了亲子交流,应加强对父母的指导和培训,对不同特征父母培训的重点应有所侧重。     

Does parental smoking cessation discourage adolescent smoking?

BACKGROUND: We examined the relationship of smoking cessation in parents to smoking and uptake and cessation by their adolescent children. METHODS: We analyzed a cross-sectional sample of 4,502 adolescents, ages 15-17 years, who lived in two-parent households that were interviewed as part of the 1992-1993 Tobacco Supplement of the Current Population Survey, which questioned householders 15 years of age and older about their smoking history. Ever smokers reported smoking at least 100 cigarettes in their lifetime. Former smokers were ever smokers who had quit. RESULTS: Multivariate analyses, adjusted for demographic characteristics of adolescents, as well as father's age, education, and family income, found that adolescents whose parents had quit smoking were almost one-third less likely to be ever smokers than those with a parent who still smoked. Furthermore, adolescent ever smokers whose parents quit smoking were twice as likely to quit as those who had a parent who still smoked. Parental quitting is most effective in reducing initiation if it occurs before the child reaches 9 years of age. CONCLUSION: Encouraging parents to quit may be an effective method for reducing adolescent smoking, through decreased uptake and increased cessation. The earlier parents quit, the less likely their children will become smokers.     

Prevalence and correlates of smoking and sexual activity among Hong Kong adolescents.

PURPOSE: To report on the prevalence and correlates of smoking and sexual activity in a community sample of Hong Kong Chinese adolescents. METHODS: Participants (N = 4116) aged 13 to 18 years were surveyed regarding smoking and physical heterosexual activity, relationships with family members, family involvement, social support, school performance and emotional adjustment. Data were analyzed using logistic regression analyses. RESULTS: About 30% of participants reported ever smoking and 3.5% reported sexual intercourse. Current smoking was correlated with age, school performance and quality of relationship with mother. Sexual intercourse was correlated with age, gender, family involvement and social support. Smoking and sexual activity were significantly correlated with each other. Smoking and increasing levels of heterosexual physical contact were negatively correlated with emotional adjustment, even after controlling for common predictors to health-endangering behaviors and emotional adjustment. CONCLUSIONS: Smoking and sexual activity among adolescents are far less common in Hong Kong than in the West and their presence in a Hong Kong adolescent should alert the health practitioner to the possibility of significant psychosocial stress and maladjustment.     

Gender Norms and Age-Disparate Sexual Relationships as Predictors of Intimate Partner Violence,Sexual Violence,and Risky Sex among Adolescent Gang Members

Unequal gender norms and age-disparate sexual relationships can lead to power imbalances and are also associated with intimate partner violence (IPV), sexual coercion and violence, and sexual risk behaviors. The present study examined these variables from both victim and perpetrator perspectives among adolescent gang members. Age-disparate sexual relationships were defined as sex partners 5 or more years older among female participants and 5 or more years younger among male participants. Participants were recruited from a mid-sized Midwestern city and completed a 60–90-min audio computer-assisted self-interview in a community-based setting. Participants in this study included 107 female gang members (68 % African-American, 19 % Latina; mean age, 17.6) and 169 male gang members (62 % African-American, 28 % Latino; mean age, 17.7). As hypothesized, endorsing unequal gender norms toward women was significantly related to IPV victimization among female participants and perpetration among male participants, and engagement in group sex in the past month among both female and male participants (ps?<?0.05). Additionally, unequal gender norms were significantly related to male participants’ perpetrating rape (p?<?0.05). As hypothesized, female gang members who had been in age-disparate sexual relationships were significantly more likely to have experienced more IPV and report being raped and males gang members who had age-disparate sexual relationships were significantly more likely to perpetrate IPV in the past year and perpetrate rape (ps?<?0.05). Age-disparate sexual relationships were also significantly related to being gang raped among female gang members and participating in a gang rape among male gang members, and engaging in group sex among both female and male gang members (ps?<?0.05). Female participants who had been in age-disparate sexual relationships were more likely to have been pregnant (ps?<?0.05). It is essential for researchers and public health practitioners to create programs for female adolescents to reduce or avoid risky situations, such as inability to negotiate condom use with older sex partners. Additionally, programs must be developed for both female and male gang members to help them understand and identify unequal gender norms, and interpersonal and sexual coercion/violence. Early intervention will also be necessary as these adolescent gang members are already engaged in extremely high-risk, coercive, and violent behaviors.     

Gender differences in the relationship between physical activity and smoking among psychiatrically hospitalized adolescents

Physical activity has been identified as a protective factor with regard to tobacco use, such that physically active adolescents are less likely to initiate smoking, and smokers are less physically active than non-smokers. These findings, along with the well-documented benefits of exercise on mood and well-being in adults, have stimulated interest in exercise-based smoking cessation interventions. However, little research has explored the relationship between physical activity and smoking characteristics within adolescent smokers. Also, gender differences in adolescents' motives for smoking and exercise may have implications for intervention development, especially in clinical populations. The current study explored the relationship between physical activity and smoking in a sample of adolescent smokers (N = 191) and non-smokers (N = 48) receiving inpatient psychiatric treatment (61% female, mean age 15.3 years). Results indicated that smokers were less likely to be physically active than non-smokers. Additionally, there was a consistent pattern of gender differences in the relationship between smoking and physical activity within smokers. Specifically, physically active male smokers were less nicotine dependent and less prone to withdrawal symptoms, and had a trend toward greater motivation to quit, than their non-active counterparts. In contrast, physically active female smokers did not differ in dependence or withdrawal and were less motivated to quit than non-active female smokers. Taken together, these results suggest that within clinical populations of adolescent females, smoking and exercise may be used jointly as weight control strategies. Exercise-based interventions for smoking cessation for adolescent females, especially clinical populations, should address weight and body image concerns.

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.     

Adolescent depression: diagnosis, treatment, and educational attainment

In this paper, I use nationally representative longitudinal data to examine adolescent depression and educational attainment. First, I examine the individual, family, and community-level determinants of adolescent depression, diagnosis, and treatment. I find that male and minority adolescents who score high on depression scales are less likely to be diagnosed as depressed or receive treatment than female and non-Hispanic white adolescents. Additionally, I find several community-level variables to be important determinants of depression, diagnosis, and treatment. Second, I examine the importance of adolescent depression for educational attainment. Although it is uncontroversial to expect a negative relationship, most previous research uses cross-sectional data, making it difficult to adequately determine the magnitude of the effect. I find that depressive symptoms are related to educational attainment along multiple margins: dropping out of high school, college enrollment, and college type. These relationships are only found for adolescent females, and there are several interesting results across income groups. Overall, these findings suggest that further attempts to diagnose and treat adolescents with depressive symptoms are needed and that additional treatment options may be required to combat the important relationship between adolescent depression and human capital accumulation for females.     

Modifiable family and school environmental factors associated with smoking status among adolescents in Guangzhou, China

OBJECTIVE: To identify modifiable family and school environmental factors associated with Chinese adolescent smoking behaviors including never-smoking, experimental smoking, regular smoking, and attempting to quit. METHODS: A cross-sectional survey using self-reported questionnaires was conducted in Huangpu, Guangzhou in December of 2004. A total of 3957 pupils agreed to complete the questionnaires. The prevalence odds ratio (risk) of experimental smoking was compared to never-smoking, adjusting for gender and age in unconditional logistic regression analysis. The risk of regular smoking was compared to experimental smoking, and the risk of attempting quitting was analyzed in regular smokers. RESULTS: The cigarette smoking of peers, mothers, fathers, brothers, and supervising teachers, passive smoking, and seeing someone smoking on campus increased the risk of experimental smoking vs. nonsmoking, while no-smoking signs, perceived anti-tobacco atmosphere in school, and being taught smoking-related health knowledge decreased the risk. The factors associated with regular smoking compared to experimental smoking included the smoking of peers, brothers, fathers and supervising teachers, teacher's tolerance, and passive smoking. Being taught smoking-related knowledge, perceived anti-tobacco atmosphere and no-smoking signs in school were positively associated with regular smoker's attempt to quit, while supervising teacher's smoking, parents' and teachers' tolerance could delay it. CONCLUSIONS: These modifiable family and school environmental factors as well as their interaction with gender and age should be highly considered in adolescent smoking prevention in China.     

Prevalence and factors associated to sexual behavior in Puerto Rican adolescents

Sexual relations with intercourse (ASR-I) and high prevalence of teen pregnancies (19.2%, in 2002) among adolescents in Puerto Rico constitute a serious biopsychosocial problem. Studying the consequences and correlates of ASR-I in community and mental health samples of adolescents is important in designing and implementing sexual health programs. Randomized representative cross-sectional samples of male and female adolescents from 11-18 years old (N = 994 from the general community, N = 550 receiving mental health services) who had engaged in ASR-I were the subjects of this study. Demographic, family, and sexual data and the DISC-IV were collected from individual interviews. Logistic regression models, bivariate odds ratios, Chi-squares, and t tests were used in the statistical analysis. The mental health sample showed higher rates of ASR-I, lifetime reports of pregnancy and lower age of ASR-I onset for females. No gender difference in the prevalence of ASR-I was observed in both samples. Older adolescents from the community sample meeting psychiatric diagnosis criteria, and with lower parental monitoring, were more likely to engage in ASR-I, whereas in the mental health sample, adolescents with lower parental monitoring and parental involvement reported significantly more ASR-I. Prevalence of ASR-I and Risky Sexual Behavior (RSB) were almost identical. Adolescents with mental health disorders initiate and engage in ASR-I earlier and more frequently regardless of gender. Older adolescents are more likely to engage in ASR-I and parent-child relationships emerged as a highly relevant predictor of adolescent sexual behavior. The high correspondence between ASR-I and RSB has important clinical implications.     

Teenage smoking and antecedent parentalcharacteristics: A prospective study

The smoking habits of 1445 white adolescents aged 15 to 17 years were examined in relation to 16 characteristics of the family prevailing at the time the mother was pregnant with the child. Five characteristics were independently associated with teenage smoking, either for boys or girls or both: parental smoking, mother's education and age, father's education and occupation.Multiple regression showed that father's occupation was redundant for both boys andgirls, and that mother's education was redundant for boys' smoking. Parental smoking, father's education and mother's age each had predictive power for boys' smoking. For the girls, mother's education also had predictive power. In general, the major family characteristics associated at birth with later teenage smoking are parental smoking habits and socioeconomic status. The sex differences between associations of family characteristics and teenage smoking suggest that the like-sexed parents' smoking and education have the greater effect on teenage smoking, particularly for the boys. For girls, present smoking status of mother was of more importance than mother's smoking status at birth if the mother had given up smoking.     

Characteristics of males who father babies born to adolescents versus older adult women in Taiwan

Purpose: To identify characteristics of males who father babies born to adolescent mothers in southern Taiwan.

Methods: This was a population-based cross-sectional study of male partners of 1,145 primigravidas (555 adolescent primigravidas and 590 adults) in Kaohsiung County, Taiwan, which compared their reports of their male partners’ characteristics. Data were collected by a questionnaire that included demographic characteristics, health behavior problems, and attitudes toward the pregnancy.

Results: In multiple logistic regression analyses, the males who father babies born to adolescent primigravidas achieved a lower level of education; a greater age discrepancy between themselves and the mothers; a greater unemployment rate; less financial independence; more smoking, drinking, and drug abuse; less supportive attitude toward pregnancy; poorer attendance at childbirth; less provision of postpartum care for mothers and infants; and greater domestic violence than adult primigravidas (p < .05). These negative findings persist even after stratification by age discrepancy. Male partners of the adolescent mothers with an age difference of 5 years or more were more likely to report drug abuse and domestic violence than those of adult primigravidas.

Conclusions: Males who father babies born to adolescent primigravidas were found to have many negative characteristics that place their partners and offspring at risk. Questions asked of or about the father of the baby during prenatal visits may help identify pregnant adolescents who need support during pregnancy and after delivery.     

Communication about sexual issues: mothers, fathers, and friends.

PURPOSE: To identify the content, characteristics, and comfort level of discussions about sexuality held between mothers and their early adolescent children and to determine the extent to which the conversations predicted sexual values and initiation of sexual intercourse of the adolescent. METHODS: This was part of a larger study to evaluate the impact of personal family characteristics on human immunodeficiency virus risk-reduction behavior among low-income predominately African-American adolescents, ages 13-15 years. Adolescents attending a metropolitan community-based afterschool program and their mothers were invited to participate in a 1-hour interview. Mothers and adolescents were interviewed separately. The interview included questions about the type of information related to sexuality that adolescents discussed with mothers, fathers, and friends; in addition, mothers were asked what topics they discussed with their adolescents. Four hundred five adolescents and 382 mothers participated. Some mothers had more than one adolescent in the study. RESULTS: The results showed that both male and female adolescents were more likely to discuss sexual topics with their mothers than their fathers. Male adolescents were more likely than female adolescents to discuss sex-based topics with their fathers. Both male and female adolescents were less likely to discuss sex-based topics with their friends than with their mothers, but more likely to discuss these topics with their friends than their fathers. Content of conversations of male adolescents was fairly consistent among mothers, fathers, and friends, and sexually transmitted disease/acquired immune deficiency syndrome and condom use were popular topics of discussion. Female adolescents tended to talk about the menstrual cycle with their mothers, sexual abstinence with their fathers, and sexual intercourse with their friends. Adolescents who reported a greater number of topics discussed with their mothers were more likely not to have initiated sexual intercourse and to have conservative values, whereas adolescents who reported a greater number of topics discussed with their friends were more likely to report the initiation of intercourse and more "liberal" sexual values. Both male and female adolescents were most comfortable discussing sexual issues with their friends. Male adolescents were less comfortable talking to mothers, but more comfortable talking to their fathers than were females. Mothers were likely to report feeling very comfortable talking about almost all discussion areas. Fathers' comfort level was not measured, as they were not directly questioned. CONCLUSION: Early adolescence (13-15 years old) is characterized by more sex-based discussions with mothers than friends or fathers. Daughters and sons discuss different topics with their fathers, although discussion by both genders with fathers is limited. If an adolescent talks more with the mother about sexual issues than with friends, he/she is less likely to initiate sexual intercourse and more likely to have conservative values. This points to the importance of fostering good communication and comfort between parents and adolescents about sexual issues.     

Smoking among adolescents in China: an analysis based upon the meanings of smoking theory

PURPOSE: This study utilized the Meanings of Behavior theory to examine whether meanings of smoking differ among adolescents in China who were never smokers, ever smokers, and past-30-day smokers. The Meanings of Behavior theory argues that affect takes precedence over cognitive constructs in motivating behavior This study also examined whether the associations among meanings of smoking and smoking behavior vary by age and gender DESIGN: This study was a cross-sectional study using survey data. SETTING: Middle and high schools in seven cities in China. SUBJECTS: A random sample of 4724 students comprised this study. MEASURE: A self-administered questionnaire asked about smoking behavior and incorporated the meanings of smoking scale. RESULTS: Overall prevalence rates of ever smokers and past-30-day smokers in this sample were 24.3% and 9.0%. Smoking was much more prevalent in boys than in girls. Students in the 11th grade were more likely than those in the 7th grade to have tried smoking at some time and to have smoked within the past 30 days. Odds ratios confirmed that meanings of smoking were significantly associated with smoking behaviors. CONCLUSIONS: Meanings of smoking are associated with smoking behavior among Chinese adolescents in that smoking may connote autonomy, control, or social relatedness. Prevention programs in China require new strategies to incorporate meanings of smoking in order to meet adolescent psychological needs for autonomy, competence, and social connections.     

Perceived risks and benefits of smoking: differences among adolescents with different smoking experiences and intentions

BACKGROUND: Explanations of adolescent smoking often make reference to adolescents' beliefs that they are invulnerable to harm. However, empirical examination of whether adolescents do acknowledge risks. Further, few studies have considered perceived benefits in adolescents' behavioral decisions. This study examined perceived smoking-related physical and social risks and benefits between adolescents who have vs. have not smoked and do vs. do not intend to smoke. METHODS: Three hundred and ninety-five students (mean age = 14.0) completed a survey concerning their smoking experiences, intentions, and perceived risks and benefits of smoking. RESULTS: Adolescent smokers and those who intend to smoke estimated their chance of experiencing a smoking-related negative outcome as less likely than did nonsmokers and non-intenders. Smokers and intenders also reported the chance of addiction as less likely than did others. In contrast, adolescent smokers and intenders perceived the chance of experiencing a smoking-related benefit as more likely than did nonsmokers and non-intenders. CONCLUSIONS: The data suggest that rather than solely focusing on health risks as a way to deter adolescent smoking, the role of perceived social risks and benefits in adolescents' smoking may be an additional critical focus for intervention. In addition, efforts should be made to increase adolescents' awareness of the addictive nature of cigarettes.     

Parental,family, and home characteristics associated with cigarette smoking among adolescents

PURPOSE: This study examines the relationship between smoking-related parental, family, and home factors with adolescents' cigarette use. DESIGN: Cross-sectional surveys of adolescents, via a self-administered questionnaire in classrooms, and their parents, via a telephone interview, were conducted. SETTING: Fifteen suburban and rural communities within Minnesota. SUBJECTS: The study sample included 8th, 9th, and 10th grade public school students and their parents. MEASURES: The dependent variable was monthly tobacco use among students. The independent measures were parental, family, and home smoking-related characteristics. There were 1343 parent-child dyads with completed surveys. RESULTS: The final, multivariate logistic regression model found the following variables to be independently related to higher smoking rates among adolescents: child's grade (odds ratio [OR] = 3.03 for 10th vs. 8th), parents' permissiveness of adult smoking (OR = 1.80), parents' having higher normative estimates of how many people smoke (OR = 1.70), parents' decreased likelihood of punishing their teenager for smoking (OR = 1.65), smoking by an adult living in the home (OR = 1.99), and sibling smoking (OR = 8.95). Lack of communication about consequences for breaking family smoking rules was associated with lower smoking rates among adolescents (OR = .49). CONCLUSION: The results of this study highlight the importance of parental smoking norms and attitudes and smoking role models in the home. It is important that smoking prevention strategies target and include the entire family. Limitations of the study are its cross-sectional design and that the sample was primarily white.     

The effects of race/ethnicity, income, and family structure on adolescent risk behaviors

OBJECTIVES: The study examined the unique and combined contributions of race/ethnicity, income, and family structure to adolescent cigarette smoking, alcohol use, involvement with violence, suicidal thoughts or attempts, and sexual intercourse. METHODS: Analyses were based on the National Longitudinal Study of Adolescent Health. A nationally representative sample of 7th to 12th graders participated in in-home interviews, as did a resident parent for 85.6% of the adolescent subjects. The final sample included 10,803 White, Black, and Hispanic 7th to 12th graders. RESULTS: White adolescents were more likely to smoke cigarettes, drink alcohol, and attempt suicide in the younger years than were Black and Hispanic youths. Black youths were more likely to have had sexual intercourse; both Black and Hispanic youths were more likely than White teens to engage in violence. Controlling for gender, race/ethnicity, income, and family structure together explained no more than 10% of the variance in each of the 5 risk behaviors among younger adolescents and no more than 7% among older youths. CONCLUSIONS: Findings suggest that when taken together, race/ethnicity, income, and family structure provide only limited understanding of adolescent risk behaviors.     

Moderation and Mediation in the Relationship Between Mothers'' or Fathers'' Serious Psychological Distress and Adolescent Substance Use: Findings from a National Sample

PURPOSE: This study estimated percentages of adolescents living with a mother or father with serious psychological distress (SPD), and examined moderation and mediation of the relationships between mother or father SPD and adolescent substance use. METHODS: We analyzed data from nationally representative samples of adolescents interviewed with their mothers (n = 4734) and fathers (n = 3176) in the combined 2002 and 2003 National Surveys on Drug Use and Health (NSDUHs). RESULTS: An estimated 4.1% of adolescents living with their father had a father with SPD during the past year, and 11.5% of adolescents living with their mother had a mother with SPD during this time period. A positive association was found between mothers' SPD and adolescent binge drinking (OR = 1.49, 95% CI = 1.01-2.21), but no association was found between fathers' SPD and adolescent binge drinking. Mothers' SPD was associated with increased risk of binge drinking among adolescents aged 14-15 years (OR = 2.52, 95% CI = 1.38-4.60), and fathers' SPD was associated with lowered risk of binge drinking among black adolescents (OR = .08, 95% CI = .01-.79). A positive association was found between mothers' SPD and adolescent illicit drug use (OR = 1.55, 95% CI = 1.08-2.23), but no association was found between fathers' SPD and adolescent illicit drug use. Mothers' SPD was associated with increased risk of illicit drug use among female adolescents (OR = 2.14, 95% CI = 1.24-3.70) and among adolescents of white ethnicity (OR = 1.78, 95% CI = 1.19, 2.68). Parental involvement partially mediated the relationship between mothers' SPD and daughters' illicit drug use; mothers' SPD was associated with lower levels of parental involvement, which in turn were associated with an increased probability of daughters' illicit drug use. CONCLUSIONS: Overall, parents' SPD is associated differentially with adolescent substance use depending on the gender of parent and adolescent, adolescent age, race/ethnicity, and substance used. Parental involvement appears to be one mechanism through which mothers' SPD influences daughters' illicit drug use. Future research should further consider the interindividual effects of parents' SPD and associated parenting behaviors on adolescent risk behaviors.
