Peer and parent influences on smoking and drinking among early adolescents.

Social influences can promote or discourage adolescent substance use. The authors surveyed 4,263 sixth- to eighth-grade students to assess the effect of peer and parent influences on adolescent substance use. The authors conducted separate multiple logistic regression analyses for smoking and drinking, controlling for grade, sex, and race. Positive independent associations with smoking and drinking were found for direct peer pressure and associating with problem-behaving friends. Independent negative associations with smoking and drinking were also found for parent involvement, parent expectations, and parent regard. In an analysis of interactions, peer pressure was positively associated with drinking for girls but not for boys and problem-behaving friends was positively associated with drinking for both boys and girls. The findings are consistent with the hypothesis that associating with deviant peers promotes and that authoritative parenting protects against smoking and drinking.

Psychosocial, school, and parent factors associated with recent smoking among early-adolescent boys and girls.

BACKGROUND: Experimentation with smoking often begins during adolescence, but an adequate understanding of the factors associated with early initiation remains elusive. METHODS: Sixth- to eighth-grade students (n = 4,263, 67.1% white, 23.5% black, 7.2% other) from seven middle schools were surveyed. RESULTS: The overall prevalence of recent smoking (past 30 days) of 10.4% was similar for boys and girls and by race, but increased from 3.7% in sixth to 17.8% in eighth grade. In multiple logistic regression analyses positive outcome expectations, high perceived prevalence, deviance acceptance, and trouble at school were independently associated with smoking for both boys and girls. Among boys, problem-behaving friends, peer pressure, authoritative parenting, and mother's education and among girls, self-control problems, knowledgeable parents, and grade were independently associated with smoking. CONCLUSIONS: This is one of the few studies to report an independent association between smoking and outcome expectations, the first study to report an independent effect for peer influences among boys only, and one of several to find a negative association between smoking and positive parenting behavior. These findings suggest that the effectiveness of preventive interventions might be improved by targeting parent, school, and student outcomes, including outcome expectations, deviance acceptance, and social norms for both boys and girls, peer influences among boys, and self-control among girls.

Student-school bonding and adolescent problem behavior.

Adolescent problem behavior, including substance use, school misconduct and delinquency, is a national concern. Implicit in the concept of middle school is the recognition that students who develop positive social bonds with their school are more likely to perform well academically, and refrain from misconduct and other antisocial behavior. However, little scientific attention has been given to the complex interactions between middle school students and the school environment. Prior to implementing a middle school problem behavior prevention program we conducted a survey in the seven middle schools in one US school district. Out of 4668 grade 6-8 students enrolled, 4263 (91.3%) completed the survey. Student-school bonding was positively correlated with school adjustment (r = 0.49) and perceived school climate (r = 0.77), but inversely correlated with problem behavior (r = -0.39 to -0.43). Problem behavior was significantly higher (P < 0.001) among males than females and among students in higher grades. Conversely, school bonding, climate and adjustment were significantly higher (P < 0.001) among females than males, but declined significantly from one grade to the next. The data support the conclusion that school bonding is associated with problem behavior. We describe the development of a multiple-component intervention in middle schools designed to increase student-school bonding and prevent problem behavior.

Depressant substances in adolescent medicine.

The benzodiazepines have replaced widespread use of barbiturates and other sedatives. They are effective, safe medicines used to treat a variety of disorders associated with excessive CNS excitability. Although many physicians avoid prescribing benzodiazepines to adolescents, there is little evidence to support this practice. Unless an adolescent has a history of substance abuse/dependence and suicidal ideation, the benzodiazepines are safe. Benzodiazepine toxicity rarely occurs unless another CNS depressant, especially alcohol, is used concurrently.

Laxative abuse: a hazardous habit for weight control.

Laxative abuse is an increasingly popular weight-loss method on college campuses, particularly for individuals with eating disorders. It is a dangerous habit, which many mistakenly believe will prevent caloric absorption and weight gain. Serious medical problems that may occur with laxative abuse include electrolyte and fluid imbalance, structural and functional colonic changes, and allergic reactions. Because patients are often secretive about abusing laxatives, laxative abuse should be considered if there is suspicion about the use of potentially destructive weight-control methods or about an eating disorder. A complete history and physical exam are essential parts of an assessment that should also include questions about diet, eating and exercise habits, and body image. Laboratory tests may provide additional supportive data. Treatment includes education, discontinuation of laxatives, medical follow-up as necessary, and psychotherapy. A college campus is an ideal forum for education, referral, and prevention programs.

The Stanford Adolescent Heart Health Program.

This study was designed to create, implement, and test a school-based multiple risk factor reduction program for high school students. All tenth graders in four senior high schools (N = 1447) from two school districts participated in the study. Within each district, one school was assigned at random to receive a special 20-session CVD risk reduction intervention and one school served as a control. The schools were matched for size and distribution of racial groups before randomization. At a two-month follow-up, knowledge gains were significantly greater for students in the treatment group on each of the risk factor domains tested: nutrition/diet (p less than 0.0001), physical activity (p less than 0.0001), and cigarette smoking (p less than 0.0001). Compared to controls, a higher proportion of those in the treatment group who were not exercising regularly at baseline, reported regular exercise at follow-up (p less than 0.0003). Almost twice as many baseline experimental smokers in the treatment group reported quitting at follow-up while only 5.6% of baseline experimental smokers in the treatment group graduated to regular smoking compared to 10.3% in the control group (p = 0.009). Students in the treatment group were more likely to report that they would choose heart healthy snack items (p less than 0.0001). Beneficial treatment effects were observed for resting heart rate (p less than 0.0001), BMI (p = 0.05), triceps skinfold thickness (p = 0.003), and subscapular skinfold thickness (p = 0.01). The results suggest that it is feasible to provide CVD risk reduction training to a large segment of the population through school-based primary prevention approaches.

Perspectives on adolescent substance use. A defined population study.

We asked 1447 tenth graders to complete a survey on physical activity, nutrition, stress, and substance use and to undergo basic physical assessments. In a multiple regression analysis, increased level of substance use by both boys and girls was most strongly predicted by friends' marijuana use. For boys, this was followed by perceived safety of cigarette smoking; poor school performance; parents' education; and use of diet pills, laxatives, or diuretics for weight control, accounting for 44% of the overall variation in substance use. For girls, friends' marijuana use was followed by poor school performance; self-induced vomiting for weight control; perceived safety of cigarette smoking; use of diet pills, laxatives, or diuretics for weight control; parents' education; perceived adult attitudes about cigarettes; and nonuse of seat belts, accounting for 53% of the overall variance. Separate multiple regression analyses for each substance produced similar results. The homogeneity of the study population precluded ethnic comparisons. These findings suggest that for many purposes substance use may be considered a single behavior regardless of the specific substance(s) used and that substance use may exist as part of a syndrome of adolescent problem behaviors. In addition, the potent influence of perceived social environment suggests that a social influence resistance model may represent the most successful preventive strategy.

Depressive symptoms and substance use among adolescent binge eaters and purgers: a defined population study.

We surveyed 646 tenth grade females in Northern California to assess the prevalence of binge eating and purging behaviors. Of these, 10.3 per cent met study criteria for bulimia and an additional 10.4 per cent reported purging behaviors for weight control. Bulimics and purgers were heavier, had greater triceps and subscapular skinfold thicknesses, and reported higher rates of drunkenness, marijuana use, cigarette use, and greater levels of depressive symptomatology.

Self-induced vomiting and laxative and diuretic use among teenagers. Precursors of the binge-purge syndrome?

Bulimia (binge-purge syndrome) is a recently described but apparently common eating disorder. Purging behaviors associated with bulimia can cause serious medical complications. Prevalence data on purging behaviors are lacking for younger adolescents. A survey was conducted with 1,728 tenth-grade students to assess their attitudes about eating, dieting, weight control, and frequency of purging. Height, weight, and skin-fold thicknesses were also measured. Thirteen percent reported purging behavior. Female purgers outnumbered male purgers 2 to 1. Male purgers were significantly heavier than male nonpurgers and had significantly greater skin-fold thicknesses and weight/height2 ratios. Both male and female purgers felt guiltier after eating large amounts of food, counted calories more often, dieted more frequently, and exercised less than nonpurgers. Our findings suggest that an alarming number of young adolescents may employ unhealthy weight regulation strategies. Physicians who see adolescents should look for the presence of the attitudes and behaviors that characterize bulimia; this will enhance the likelihood of detection of the disorder and prevention of its complications.

Correlates of seat-belt use by adolescents: implications for health promotion.

This study examined the psychosocial and behavioral correlates of seat-belt use among 1,728 10th-graders in four Northern California high schools. Parent and friend seat-belt use patterns were most highly correlated with student seat-belt use (r = 0.66 and r = 0.61, respectively) and together accounted for 46% of the variation in use. These relationships held across differences in sex, ethnicity, and socioeconomic status. Failure to wear seat belts was associated with a higher use of alcohol, cigarettes, marijuana, and cocaine; more tolerance toward speeding and drinking while driving; less exercise; and more preference for fat in the diet. Our findings attest to the power of parent and peer influences in shaping seat-belt use by adolescents and suggest that not wearing seat belts can be conceptualized as one facet of a pattern of general risk-taking behavior. These findings suggest several possible educational interventions to increase seat-belt use by adolescents.

Modifying the snack food consumption patterns of inner city high school students: the Great Sensations Study.

The Great Sensations Program is a nutrition-education project developed for high school students. It was designed to (a) decrease students' consumption of salty snacks and (b) increase students' consumption of fresh fruit snacks. The overall programs were designed following principles of social learning: informative instruction, participatory classroom activities, personal goal setting, feedback, and reinforcement. The program was delivered in six lessons during regular health-education classes. A parental involvement program consisted of mailers and telephone calls to parents to teach them to encourage changes in student snacking habits. A schoolwide program was designed to provide out-of-class peer support for student modifications in salty snack foods. The program was evaluated in one high school using a 2 X 2 design. A second high school served as a no-treatment control. Program assessments were made at both schools before and after the classes, at the end of the school year, and the following fall the next school year following summer vacation. The schoolwide media program was effective in decreasing consumption of salty snack foods and in increasing consumption of target snack foods. However, only those students receiving classroom instruction maintained those changes until the end of the school year. No changes were maintained across summer vacation. These outcomes suggest that school programs developed using principles of social learning may be effective in facilitating important behavior changes at home and at school.

Great Sensations: a program to encourage heart healthy snacking by high school students.

The Great Sensations program consisted of three interrelated educational strategies--classroom instruction, parent outreach, and media campaign. These strategies were designed to teach inner-city high school students about salt and high blood pressure, and to encourage them to eat more low-salt snacks and fewer high-salt snacks. Eight classes at the experimental school were randomly assigned to class instruction or parent outreach in a factoral design. All students in the experimental school were exposed to the media campaign. Students at a nearby high school served as the comparison group. All but a few of the 490 students at the two schools were black. Students who received the classroom instruction reported lower Salty Snack selection and higher Target Snack selection at posttest and eight-week follow-up. Students receiving media only reported lower Salty Snack selection at posttest but this condition returned to baseline by eight weeks. The control group reported little change in snack selection at posttest and eight weeks. After six months, program effects were no longer evident for either experimental group.

Expectancies and other psychosocial factors associated with alcohol use among early adolescent boys and girls.

Early experimentation with drinking increases the lifetime risk for substance abuse and other serious health and social problems. We studied factors associated with early alcohol experimentation by surveying 4,263 sixth- to eighth-grade students (67.1% White, 23.5% Black, 7.2% other races combined; 2.2% missing data) from seven schools in one suburban school district. The prevalence of drinking in the last 30 days was 12.1% for boys and 13.1% for girls (12.6% overall); 6.6% among sixth graders, 11.1% among seventh graders, and 19.5% among eighth graders. In multiple logistic regression analyses, controlling for grade, positive alcohol expectancies, perceived prevalence, and deviance acceptance were associated positively, self-control negatively, with drinking for both boys and girls. Among boys, grade point average was negatively associated with drinking. Among girls, propensity for risk-taking and problem-behaving friends were positively associated and high parental expectations were negatively associated with drinking. Alcohol use in our sample of early adolescent boys and girls was better explained by modifiable psychosocial factors such as alcohol expectancies, perceived prevalence, and self-control than by grade.

Promoting dietary change in adolescents: a school-based approach for modifying and maintaining healthful behavior.

We examined the immediate and long-term effects of a school-based, behaviorally focused dietary change program for tenth-graders. Our behavioral change objectives included increased consumption of complex carbohydrates and decreased intake of saturated fats, sugar, and salt, particularly in the form of snack foods. We randomly assigned tenth-grade classes in two northern California high schools to either a five-session dietary change program or an assessment-only control group. We collected pre- and postprogram self-report data on 218 students in areas of dietary knowledge, behavior, attitudes, food availability in the home, and intentions and self-efficacy concerning eating in specific ways. We also observed school snack choices both directly and indirectly. Our results indicated significant changes in reported behavior, knowledge, and food availability at home, as well as changes in snack choices at school. We found these changes to be durable at one-year follow-up. Our findings suggest ways in which school-based programs focused on behavioral and environmental changes may be effective in promoting dietary changes at school and at home.
