Adolescent problem behaviors as predictors of adult alcohol diagnoses.

Young adult alcohol problems based on DIS/DSM III diagnoses were predicted from a number of adolescent risky/antisocial behaviors in a sample of 693 subjects. The number of times an individual was intoxicated before his/her sixteenth birthday was the best indicator of adult alcohol "abuse" and /or dependence, with adolescent fighting, arrests, and lack of participation in religious activities also serving as important problem behavior predictors. Results of correlational and principal-components analyses of adolescent problem behaviors are similar to previous work on Problem Behavior Theory. The results suggest that prevention efforts should begin before adolescence, prior to the time when individuals are exposed to, or begin practicing, adult health-threatening activities.

Weight-control behaviors among adolescent girls and boys: implications for dietary intake.

OBJECTIVE: To examine associations between healthful and unhealthful weight-control behaviors and dietary intake among adolescents. DESIGN: Cross-sectional survey (Project EAT [Eating Among Teens]).Subjects/Setting The study population included 4144 middle and high school students from Minneapolis/St. Paul public schools from diverse racial and socioeconomic backgrounds. Statistical analyses Dietary intake patterns were compared across adolescent girls and boys reporting unhealthful, only healthful, or no weight-control behaviors in unadjusted analyses and analyses adjusted for sociodemographic factors and energy intake. RESULTS: Among girls, mean intakes differed across weight-control behaviors for all foods and nutrients examined. P values ranged from P=.006 to P<.001. Girls using unhealthful weight-control behaviors had significantly lower intakes of fruit; vegetables; grains; calcium; iron; vitamins A, C, and B-6; folate; and zinc than girls using only healthful weight-control behaviors. Compared with girls reporting no weight-control behaviors, girls using unhealthful weight-control behaviors had lower intakes of grains, calcium, iron, vitamin B-6, folate, and zinc. In contrast to the girls, boys reporting unhealthful weight-control behaviors did not have poorer dietary intakes than boys not using weight-control behaviors or using only healthful behaviors. Among boys, there were no significant differences in mean intakes of vegetables; grains; calcium; iron; vitamins A, C, and B-6; folate; and zinc. Furthermore, boys using unhealthful weight-control behaviors had higher fruit intakes (P=.002) than boys reporting no weight-control behaviors. CONCLUSIONS: Adolescent girls who engage in unhealthful weight-control behaviors are at increased risk for dietary inadequacy. The findings demonstrate a need for interventions to prevent unhealthful weight-control behaviors in adolescent girls, and to promote healthful weight-control behaviors when indicated.

Relationship between perceptual differences of parenting and adolescent antisocial behavior and depressive symptoms.

The relation between adolescent negative adjustment and differences in parent-child ratings of parents' warmth and negativity was examined with a national sample of 720 families. It was predicted that perceptual differences (PDs) would be linked to more negative adjustment. Adjustment was regressed on PDs, which were calculated as absolute differences between parent and child ratings of parenting. Results showed that PDs were significantly associated with adjustment independent of the level of parenting behavior. Associations differed by gender for PDs over maternal verbal aggression. Some of the most important results were curvilinear effects indicating that both high and low, but not medium, levels of PDs are linked with maladjustment. Finally, differences between younger and older adolescents were found: The linear relationship between PDs over parental negativity and maladjustment disappeared for older adolescents.

Knowledge and concerns about acquired immunodeficiency syndrome and their relationship to behavior among adolescents with hemophilia.

The knowledge and concerns regarding acquired immunodeficiency syndrome (AIDS) and their relationship to certain behaviors among adolescents with hemophilia, a pediatric risk group with human immunodeficiency virus (HIV) antibody positivity rate as high as 70% to 90%, are described. Information was obtained from 26 patients, 13 to 19 years of age, through the use of a confidential self-administered questionnaire and a semistructured interview. In general, subjects demonstrated a high level of factual knowledge regarding the cause, natural history, transmission, and prevention of AIDS. Despite this, participants frequently behaved in ways that were potentially harmful to themselves and others. Specifically, although aware of the importance of using condoms, sexually active adolescents with hemophilia were not practicing safe sex. Restriction in the use of heat-treated clotting factor because of concerns about AIDS was also frequently reported. Professionals providing AIDS education and counseling for these individuals need to be cognizant of the concerns and social skills of this population; they should focus not only on factual information but also on the social and situational pressures confronting these teenagers, which may be more immediate determinants of their behavior and well-being. As AIDS continues to spread into the general population, these findings have relevance to AIDS education and health policy efforts aimed at all adolescents.

Risk-taking behavior in adolescent mice: psychobiological determinants and early epigenetic influence.

Epidemiological research has emphasized that adolescence is associated with some temperamental and behavioral traits that are typical of this age and that might substantially contribute to both psychological and psychobiological vulnerability. The contribution of the important developmental rearrangements in neurobiological and neuroendocrinological processes has received surprisingly little investigation. The present review summarizes recent work in animal models, indicating that adolescent rodents exhibit marked peculiarities in their spontaneous behavioral repertoire. When compared to adults, adolescents show an unbalanced and 'extremes-oriented' behavior, consisting of an increased novelty seeking, together with decreased novelty-induced stress and anxiety, an increased risk-taking behavior in the plus-maze, as well as elevated levels of impulsivity and restlessness. Age-related discontinuities in the function of monoaminergic systems, which are a main target of abused drugs, can perhaps account for such a profile. In particular, a peculiar function within reward-related dopaminergic brain pathways actually seems to underlie the search for novel and rewarding sensations, as well as changes in the magnitude of psychostimulant effects. The role played by early epigenetic factors in the shaping of novelty-seeking behavior of adolescent and adult rodents are also reviewed. Two examples are considered, namely, subtle variations in the hormonal milieu as a function of intrauterine position and precocious or delayed maturation of nutritional independence as a function of changes in time of weaning. As for spontaneous drug consumption, a prominent vulnerability to the oral intake of nicotine during early adolescence is reported. In conclusion, adolescence in rodents may represent a suitable animal model with enough face- and construct-validity. Actually, this model is able to show behavioral features that resemble those found in human adolescents, including vulnerability to the consumption of psychoactive drugs.

Early maternal attachment behaviors of adolescent and adult mothers.

This comparison of observed attachment behaviors of 184 medically indigent, low-risk, inner-city adolescent and adult mothers addresses three critical questions unanswered by current research regarding the maternal attachments behaviors of adolescents. The 69 mothers aged 14 to 17 and the 36 mothers aged 18 to 19 exhibited significantly fewer maternal attachment behaviors during in-hospital infant feedings than a control group of 79 mothers aged 20 to 24. Verbal reports of adolescent and adult mothers were not reliable indicators of actual attachment behaviors. Two-way analyses of variance, statistically controlling for other background factors and amount of infant contact, did not diminish the impact of maternal age. However, rooming-in and educational levels appropriate for age both had additional independent impacts on maternal attachment scores.

Physical activity and sedentary behavior patterns are associated with selected adolescent health risk behaviors.

OBJECTIVE: Little is known about how physical activity (PA), sedentary behavior, and various adolescent health risk behaviors are associated. The objective of this study was to examine relationships between PA and sedentary behavior patterns and an array of risk behaviors, including leading causes of adolescent morbidity/mortality. METHODS: Nationally representative self-reported data were collected (National Longitudinal Study of Adolescent Health; wave I: 1994-1995; II: 1996; N = 11957). Previously developed and validated cluster analyses identified 7 homogeneous groups of adolescents sharing PA and sedentary behaviors. Poisson regression predicted the relative risk of health risk behaviors, other weekly activities, and self-esteem across the 7 PA/sedentary behavior clusters controlling for demographics and socioeconomic status. Main outcome measures were adolescent risk behaviors (eg, truancy, cigarette smoking, sexual intercourse, delinquency), other weekly activities (eg, work, academic performance, sleep), self-esteem. RESULTS: Relative to high television (TV) and video viewers, adolescents in clusters characterized by skating and video gaming, high overall sports and sports participation with parents, using neighborhood recreation center, strict parental control of TV, reporting few activities overall, and being active in school were less likely to participate in a range of risky behaviors, ranging from an adjusted risk ratio (ARR) of 0.42 (outcome: illegal drug use, cluster: strict parental control of TV) to 0.88 (outcome: violence, cluster: sports with parents). Active teens were less likely to have low self-esteem (eg, adolescents engaging in sports with parents, ARR: 0.73) and more likely to have higher grades (eg, active in school, ARR: 1.20). CONCLUSIONS: Participation in a range of PA-related behaviors, particularly those characterized by high parental sports/exercise involvement, was associated with favorable adolescent risk profiles. Adolescents with high TV/video viewership were less likely to have positive risk behavior outcomes. Enhancing opportunities for PA and sport may have a beneficial effect on leading adolescent risk behaviors.

Weight-related attitudes and behaviors of adolescent boys and girls who are encouraged to diet by their mothers.

OBJECTIVE: To assess the relationships between mothers' reports of dieting and encouraging adolescents to diet and adolescents' reports of their own dieting practices and weight-related concerns. DESIGN: Cross-sectional study of parent interviews and adolescent surveys in an ethnically-diverse sample. SUBJECTS: A total of 810 adolescents (n=381 boys and n=429 girls) and their mothers. RESULTS: Mothers' dieting was associated with their adolescent girls' weight-related concerns and behaviors, but these associations were not significant after adjusting for girls' body mass index (BMI). In contrast, mothers' encouragement for sons to diet was associated with sons' binge eating, dieting and other weight-control behaviors, even after controlling for sons' BMI. Compared with mothers who did not encourage their child to diet, mothers who encouraged their child to diet were significantly heavier women and were more likely to view their child as overweight. Forty-three percent of boys and 46% of girls who were encouraged by their mothers to diet were classified as nonoverweight by federal guidelines. CONCLUSIONS: Boys who are encouraged by their mothers to diet may be at risk for health-compromising eating and dieting behaviors, particularly binge-eating, fasting, eating a little bit of food and skipping meals. Parents who are concerned about their children's weight should be educated to encourage healthy eating habits and physical activity to promote their children's health, including healthy weight control.

Comparison of AIDS knowledge and HIV-related sexual risk behaviors among adolescents in low and high AIDS prevalence communities.

Data were collected from students attending high school in a rural, low acquired immunodeficiency syndrome (AIDS) prevalence community in Northern California, and compared with students in an inner-city AIDS epicenter (San Francisco). The findings demonstrate that rural adolescents have higher levels of human immunodeficiency virus (HIV) knowledge, especially about risk-reduction strategies. However, rural adolescents also report higher rates of HIV-related sexual risk behaviors. Rural adolescents may not perceive the personal salience of practicing HIV risk-reduction behaviors thus increasing their risk for exposure to sexually-transmitted diseases, including HIV infection. School-based HIV prevention programs developed for rural communities will need to enhance the personal salience of HIV for adolescents' and discourage their discounting of personal risk attributable to a lower prevalence of AIDS in the community. Physicians must become more actively involved in HIV prevention efforts by routinely assessing adolescent patient's sexual behavior and utilizing their clinical interaction to provide HIV education and promote the adoption of HIV risk-reduction behaviors.

[Influencing factors on problem behaviors among adolescents: focused on middle school students in Seoul].

PURPOSE: This study was to investigate the factors influencing problem behaviors among adolescents. METHOD: The subjects for this study were 596 students in middle school in Seoul. The data was collected during the period from May to November, 2001 by use of questionnaires. The instruments used were the Child Problem Behavior list by Hong (1986), the Body Cathexis Scale by Secord and Jourard(1953), and the Beck Depression Inventory by Beck(1978). The data was analyzed by using the SPSS-Win program. RESULT: Problem behaviors showed a significant negative correlation with body image (r= -.310. p=.000) and positive correlation with depression (r=.674, p=.000). There were significant differences in the problem behavior scores of subjects according to sex, family status, economic status, and school scores. Female students were found to have a high degree of internalized problem behaviors. In addition, depression, body image, and sex were significant predictors to explain problem behaviors(47.3%). Depression, sex, grade, and school scores were significant predictors to explain externalized problem behaviors(21.9%) and depression and body image, internalized problem behaviors(51.4%). CONCLUSION: Since predicting factors of problem behaviors among middle school students by problem behavior type and sex were different, then practitioners should consider these differences when developing programs for them.

Breakfast skipping and health-compromising behaviors in adolescents and adults.

OBJECTIVE: To investigate which sociodemographic factors and behaviors are associated with breakfast skipping in adolescents and adults. DESIGN: Five birth cohorts of adolescent twins and their parents received an extensive behavioral and medical self-report questionnaire that also assessed breakfast-eating frequency. SETTING: Finland, 1991-1995. SUBJECTS: A population sample of 16-y-old girls and boys (n=5448) and their parents (n=4660). RESULTS: Parental breakfast eating was the statistically most significant factor associated with adolescent breakfast eating. Smoking, infrequent exercise, a low education level at 16, female sex, frequent alcohol use, behavioral disinhibition, and high body mass index (BMI) were significantly associated with adolescent breakfast skipping. In adults, smoking, infrequent exercise, low education level, male sex, higher BMI, and more frequent alcohol use were associated with breakfast skipping. In the adult sample, older individuals had breakfast more often than younger ones. Both adults and adolescents who frequently skipped breakfast were much more likely to exercise very little compared to those who skipped breakfast infrequently. Breakfast skipping was associated with low family socioeconomic status in adults and adolescent boys, but not in girls. Breakfast skipping clustered moderately with smoking, alcohol use, and sedentary lifestyle in both adults and adolescents. CONCLUSIONS: Breakfast skipping is associated with health-compromising behaviors in adults and adolescents. Individuals and families who skip breakfast may benefit from preventive efforts that also address risk behaviors other than eating patterns. SPONSORSHIP: National Institute of Alcohol Abuse and Alcoholism (AA08315), Academy of Finland (44069), European Union Fifth Framework Program (QLRT-1999-00916), Yrjö Jahnsson Foundation, and Jalmari and Rauha Ahokas Foundation.

Alcohol abuse and risk behavior among adolescents in larger cities in Bosnia and Herzegovina.

OBJECTIVE: To investigate adolescents who abuse drugs and to describe aspects of risk behavior among alcohol abusers. METHOD: study was conducted on 598 adolescents, aged 12-17 years, with equal distribution in rural and urban areas. Study was based on self-reported questionnaire Q 2000. Study designed as prospective, epidemiological, analitical. Results have been compared within groups, between cantons and among groups. Evaluation of data was done using EPI-info software, with standard statistic methods. RESULTS: Out of the total number of 598 adolescents 15.55% had abused alcohol (urban 62.4%, rural 37.6%); 6.69% tobacco (urban 67.5%, rural 32.5%); 3.34% cannabis (urban 70.0%, rural 30.0%). Results show various aspects of risk behavior among adolescents who consume alcohol such as: truancy 44.1%; low success at school 14.0%; suicidal thoughts 36.6%; unprotected sex 17.7%; drunken driving 10.0%; non use of seat belts 24.7%; deliquency (stealing) 22.2%; destructive behavior 18.9%. Adolescents who abuse drugs have planned to continue with similar behavior in the future: to abuse drugs 31.6%; to smoke 52.2%, to drink alcohol 44.4%, to fight 27.8%; to drive without seat belt 36.8%; to have unprotected sex 16.7%. Risk behavior related to cannabis abuse and tobacco smoking is also described. CONCLUSION: Data suggests that major aspects of adolescents' risk behavior is related to alcohol abuse, what should be considered while designing prevention activities and programmes.

Overweight status and weight control behaviors in adolescents: longitudinal and secular trends from 1999 to 2004.

BACKGROUND: This study examined 5-year longitudinal and secular trends in weight status and the use of healthy and unhealthy weight control behaviors in adolescents. METHODS: Project EAT-II followed 2516 adolescents from Minnesota longitudinally from 1999 to 2004. The population included two cohorts allowing for the observation of transitions from early to middle adolescence (junior high school to high school) and from middle to late adolescence (high school to post-high school). RESULTS: The prevalence of overweight (females: 28.7%; males: 28.0%) was high in early adolescence and remained high throughout adolescence. In females, between early and middle adolescence, there were steep longitudinal increases in the use of unhealthy weight control behaviors (48.6% to 58.8%, P = 0.001) and extreme weight control behaviors (9.4% to 17.9%, P < 0.001), and between middle and late adolescence, extreme weight control behaviors increased from 14.5% to 23.9% (P < 0.001). In males, extreme weight control behaviors doubled from middle to late adolescence (3.4% to 6.3%, P = 0.023). Use of diet pills doubled from 7.5% to 14.2% from 1999 to 2004 (P = 0.004) in high school females. One fifth (19.9%) of females in late adolescence reported taking diet pills. CONCLUSIONS: Overweight status and unhealthy weight control behaviors in adolescents are major public health concerns that warrant interventions addressing both problems.

Mood and behavior at adolescence: evidence for hormonal factors.

We studied the relationship among behavior, mood, pubertal development, hormonal levels, and psychological functioning in 100 adolescent white girls between the ages of 10.6-13.3 yr. The girls were grouped by pubertal breast stages and four stages of estradiol secretion. No significant mood or behavior changes were found as a function of pubertal stages, controlling for age effects, except for a decrease in interest in sports. The hormonal stages revealed a significant curvilinear trend for depressive affect (increase, then decrease; P less than 0.01), impulse control (decrease, then increase; P less than 0.04), and psychopathology (increase, then decrease; P less than 0.03) scales, indicating significant changes in these behaviors during times of rapid increases in hormone levels. These data suggest that hormonal changes may be more important than the physical changes as determinants of certain mood and behavior patterns at adolescence.

Violence exposure and emotional trauma as contributors to adolescents' violent behaviors.

OBJECTIVE: To investigate the degree to which violence exposure and symptoms of psychological trauma are related to adolescents' own violent behaviors. DESIGN AND SETTING: Anonymous self-report questionnaire administered to students in 6 public high schools (grades 9-12). PARTICIPANTS: Sixty-eight percent of the students attending the participating schools during the survey participated in the study (N=3735). Ages ranged from 14 to 19 years; 52% were female; and 35% were African American, 33% white, and 23% Hispanic. RESULTS: Multiple regression analysis determined that violence exposure and symptoms of psychological trauma together explained more than 50% of the variance in both male and female self-reported violent behavior. The independent effects of exposure to violence explained about one quarter of the variance in both male and female adolescents' violent behaviors. Anger was found to be the leading trauma symptom. CONCLUSION: Our findings suggest that health clinicians and other professionals who encounter adolescents should routinely screen them for both exposure to violence and symptoms of anger.

Examining the relationship between gender and drug-using behaviors in adolescents: the use of diagnostic assessments and biochemical analyses of urine samples.

The present study examined the relationship between gender and drug-use among adolescents using diagnostic assessments and biochemical analyses of urine samples. The data were collected in the context of a referral and assessment program for adolescents suspected of using drugs, using the Adolescent Substance Battery [1]. A six-month random sample of 20 percent of adolescents assessed for drug use were targeted for biochemical assay. Compliance for urine delivery was relatively high at 91 percent. Urine samples were quantitatively screened for pharmaceuticals using a standard thin-layer chromatography (TLC) technique [2]. Statistical significance was found in the relationship between gender and marijuana use (p < .05). This study confirms that gender and drug-using behaviors among adolescents need additional research and evaluation.

Japanese national survey of adolescent drinking behavior in 1996.

BACKGROUND: Despite legal prohibition of drinking by minors, there has been no systematic attempt to monitor drinking by young Japanese. This research, the first Japanese national survey of Japanese adolescent drinking behaviors, was conducted in 1996. METHODS: In this survey, information on drinking frequency was obtained from questionnaires completed by 42,183 junior high school and 72,396 senior high school students in randomly selected schools representing all areas of Japan. RESULTS: Sixty percent of junior high school students and 70% of senior high school students reported having drinking experiences; 5% of junior high school students and 10% of senior high school students drank one or more times per week. Many of the junior high school students usually drank with their families and consumed small amounts, but many of senior high school students drank on various occasions and consumed larger amounts. These Japanese high school students reported being offered alcohol frequently by their parents, found it easy to buy alcoholic beverages, and believed that they had the right to determine whether to drink. Japanese adolescents' drinking has increased over the past 20 years, whereas drinking by U.S. adolescents has decreased. CONCLUSIONS: Japanese policies aimed at decreasing adolescent drinking are inadequate. A system for monitoring and potentially modifying adolescent drinking behavior is needed.
