Cigarette smoking, major depression, and other psychiatric disorders among adolescents

A longitudinal study of developmental trajectories to young adult cigarette smoking

This study examined smoking trajectories between adolescence and adulthood in an African American cohort followed prospectively from first grade to age 32. We classified non-smokers, former smokers, current smokers/late adopters (initiated after age 18), and current smokers/early adopters (initiated before age 17). Results show that almost half of the population were currently smoking. Multiple logistic regression analyses showed that non-smokers differed most from the three smoking groups on social integration. Non-smokers were less likely to have left home before the age of 18, to have had more drug use parental supervision as an adolescent, to have moved less, and to attend church more frequently as an adult. Those current smokers who initiated early differed from the non-smokers and also from the former smokers and the current smokers who adopted smoking after the age of 18; they were more likely to be rated as aggressive or both shy and aggressive by their first grade teachers and to have drug problems as adults. Current smokers were less likely to attend church as adults than the non-smokers and former smokers. Neither mother's smoking or lifetime depression was related to smoking. The findings elucidate the contribution of factors over the life course that have an impact on smoking initiation, continuation, and cessation. They highlight the importance of targeting African American children and adolescents for prevention despite the fact that African American youth have the lowest rates of smoking across all ethnic groups. Possible interventions could be aimed at early aggressive behavior, parental supervision and monitoring, and other social integration efforts.

Anxiety sensitivity: relationship to negative affect smoking and smoking cessation in smokers with past major depressive disorder

The present study evaluated whether anxiety sensitivity (AS) was related to negative reinforcement smoking motives and increased risk of relapse during the early stages of a quit attempt. Specifically, the role of AS was evaluated in 60 smokers with past major depressive disorder (MDD) during smoking cessation. Consistent with expectations, AS scores, as indexed by the 16-item Anxiety Sensitivity Index (ASI) [Behaviour Research and Therapy 24 (1986) 1], were positively correlated with smoking to reduce negative affect but were not significantly correlated with smoking for other reasons. Higher ASI scores also were associated with increased risk of lapsing during the first 7 days after quit day. Results suggest that smokers with heightened levels of AS may smoke more often to manage negative moods and may be less able to tolerate early withdrawal symptoms, specifically during early stages of a quit attempt.

Adolescent depression: a review

OBJECTIVE

To review the characteristic clinical, illness course and risk factors to adolescent depression.

METHOD

A literature review is provided with interpretive comments.

RESULTS

The clinical feature profile is likely to reflect the rarity of melancholic depression, while the non-melancholic "irritable hostile" pattern appears distinctly increased. A "reactive depressive disorder" is rare in those who get to psychiatric assessment, while comorbidity (e.g. anxiety and personality disorders, illicit drug use) is the rule. Aetiological determinants and the prognosis generally more relate to comorbid factors than to depression per se. Predisposing and precipitating psychological and social determinants are considered, while the efficacies of varying antidepressant strategies remain unclear apart from those with an "anxious" or "irritable" depression where selective serotonin re-uptake inhibitor medication has shown utility and where cognitive-behavioural therapy may be relevant.

CONCLUSIONS

For the majority who develop adolescent depression, its expression and outcome appear more a reflection of the propagating determinants, most commonly anxiety and personality style. The clinician should determine a treatment plan that not only addresses the depression but which identifies and addresses the contributing features.

Association between psychiatric disorders and the progression of tobacco use behaviors

OBJECTIVE

To examine the progression of tobacco use and the patterns of comorbidity of tobacco use and psychiatric disorders.

METHOD

The authors conducted analyses of prospective and retrospective reports, collected from 1988 to 1998, of a sample of high- and low-risk youths identified on the basis of the presence or absence of a parental history of substance abuse or dependence.

RESULTS

A parental history of substance use disorders was associated with regular tobacco use and nicotine dependence, but not with experimentation for all youths. Individual and composite psychiatric diagnoses were strongly associated with nicotine dependence, but not with regular use or experimentation. While the presence of an affective disorder and drug abuse/dependence generally increased the risk for co-occurring nicotine dependence, analyses based on the temporal onset of disorders showed that it was the initiation of alcohol or drug use that predicted the progression to nicotine dependence. For low-risk youths, oppositional defiant disorder was the single psychiatric risk factor that predicted the transition to nicotine dependence.

CONCLUSIONS

This study adds to the accumulating evidence that has implicated comorbid psychiatric disorders in the etiology and subsequent course of nicotine dependence. In addition, family history may represent an important indicator of an increased risk for nicotine dependence.

Depression and smoking: examining correlates in a subset of depressed patients

OBJECTIVE

The objective of this study was to examine for associations between depression and cigarette smoking.

METHOD

A sample of 92 depressed smokers was compared with a control sample of depressed non-smokers, matched for age, gender and diagnostic variables. Comparisons were made across a range of demographic, depression, family history, developmental factors, anxiety and personality style variables, as well as use of alcohol and illicit drugs.

RESULTS

We failed to find any difference between smokers and non-smokers in history or severity of depression. Cigarette smokers were distinguished principally by greater exposure to aversive experiences in childhood, disordered personality function, greater use of illicit drugs, anxiolytics and alcohol. Logistic regression identified dysfunctional personality 'domains', physical violence in childhood, long-term anxiolytic use and illicit drug use as the most significant predictor set.

CONCLUSIONS

Results favour a model of cigarette smoking and depression as linked by shared early deprivational variables, rather than cigarette smoking causing depression or the converse.

A pessimistic attitude towards the future and low psychosocial functioning predict psychiatric diagnosis among treatment-seeking adolescents

OBJECTIVE

The objective was to study factors associated with psychiatric diagnosis among adolescents (n = 164) seeking psychiatric care for mental symptoms.

METHOD

Psychiatric diagnosis was confirmed by a structured diagnostic interview. Psychosocial functioning was assessed with the Global Assessment of Functioning Scale, and the Beck Depression Inventory and Offer Self-Image Questionnaire were also used. Background data were gathered.

RESULTS

A majority (76%) of the adolescents met DSM-III-R criteria for psychiatric diagnosis. The self-image was more negative and the Beck score was higher among these adolescents than the others. All who had attempted suicide had a psychiatric disorder. Those diagnosed as having a psychiatric disorder consumed alcohol in order to get drunk more often than others. Continual conflicts with parents and smoking were not associated with the existence of a psychiatric disorder. In logistic regression analysis, low psychosocial functioning (OR = 3.9) and an uncertain or pessimistic attitude towards the future (OR = 9.1) proved to be independent risk factors for psychiatric disorders.

CONCLUSIONS

Health service staff should be aware of factors associated with psychiatric disorders in adolescents so that they can identify those at high risk.

Smoking and mental health: cross-sectional and cohort studies in an occupational setting in Japan

BACKGROUND

The relationship between smoking and mental health remains unclear.

METHODS

We carried out a cross-sectional study and a cohort study on the possible association of smoking and mental health in 782 workers. Using a questionnaire including the 30-item General Health Questionnaire (GHQ-30) and items related to the smoking state, the association between smoking and mental health was evaluated separately in males and females. The subjects were classified into smokers and nonsmokers, and changes in the GHQ score during a 2-year follow-up period were evaluated. To control potential confounding factors, multiple regression analyses were performed.

RESULTS

The cross-sectional study showed no difference in the GHQ score between smokers and nonsmokers among males but a significantly higher GHQ score for smokers than nonsmokers among females. This difference among females was confirmed to be significant by multiple regression analysis. The 2-year cohort study showed a decrease in the GHQ score in each group and no reduction in the difference in the GHQ score between smokers and nonsmokers among females.

CONCLUSIONS

No difference was observed in mental health between smokers and nonsmokers in males. However, in females, smokers showed poorer mental health than nonsmokers, and this difference remained unchanged even after 2 years.

Prevention of nicotine addiction: neuropsychopharmacological issues

Most children and adolescents try smoking cigarettes; up to two-thirds discontinue. What explains the one-third or more who continue smoking? What physiological, pharmacological, and other environmental factors affect the risk of developing a pattern of chronic tobacco use? How can the transition from occasional use to chronic use be slowed, if not halted? What are the safest, most effective means of intervention for those children and adolescents who develop patterns of chronic daily cigarette smoking and would like to quit? How can they be motivated to want to quit? These are just a few of the issues that might be resolved in part by further neuropsychopharmacological research, but the challenges and barriers to conducting such research on children and adolescents are substantial. The barriers may be better understood by a brief summary of what neuropsychopharmacology research involves, and a corresponding summary of the disincentives to conduct such research.

Adolescent smoking cessation: how effective have we been?

Adolescent smoking, at its current rate, is considered a pediatric epidemic, with 3,000 youths less than 18 years of age becoming regular smokers each day (Johnson, O'Malley, & Bachman, 1998). The reasons adolescents begin and continue to smoke are multifactorial. There is a paucity of research describing effective adolescent smoking-cessation programs. Much of the research on adolescent tobacco use has focused on correlates and prevention of onset, rather than on intervention with active smokers. Current research indicates that 75% of adolescents who currently smoke want to quit. It is essential that nurses involved with adolescent health promotion become active in smoking-cessation efforts. This article describes the risk factors for adolescent smoking and identifies smoking-cessation strategies, with interventions specific to the adolescent population.

Determinants of attrition from cessation treatment in smokers with a history of major depressive disorder

Attrition from smoking cessation treatment by individuals with a history of major depression was investigated. An investigation of preinclusion attrition examined differences between eligible smokers who did (n = 258) and did not (n = 100) attend an initial assessment session. Postinclusion attrition was investigated by comparing early dropouts (n = 33), late dropouts (n = 27), and treatment completers (n = 117). Those who failed to attend the assessment session were more likely to be female, to smoke cigarettes with higher nicotine content, and to have a history of psychotropic medication use. Early-treatment dropouts reported a higher smoking rate than late-treatment dropouts and endorsed more symptoms of depression than late dropouts and treatment completers. Results are compared with previous investigations of smoking cessation attrition, and implications for treatment and attrition prevention are discussed.

Predicting smoking cessation and major depression in nicotine-dependent smokers

OBJECTIVES

This study examined the relationship of nicotine dependence with smoking cessation and major depression, using the Fagerstrom Test for Nicotine Dependence (FTND) and the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R).

METHODS

In an epidemiologic study of young adults that used the FTND and the National Institute of Mental Health Diagnostic Interview Schedule, 238 daily smokers were assessed with respect to nicotine dependence. Cessation (abstinence for 1 year or more) was assessed 2 years later.

RESULTS

FTND-defined nicotine dependence predicted cessation, with non-dependent smokers 4 times more likely to quit. DSM-III-R-defined nicotine dependence also predicted cessation, but much more weakly. Number of cigarettes per day was the best predictor of cessation. FTND-defined dependence was unrelated to major depression, whereas DSM-III-R-defined dependence signaled a 3-fold risk for major depression. The association of DSM-III-R-defined nicotine dependence with major depression might be driven by the behavioral rather than the physiologic symptoms of dependence.

CONCLUSIONS

The more a measure of dependence is based exclusively on level of daily smoking, the greater is its ability to predict cessation. The number of DSM-III-R behavioral symptoms might be an indicator of severity of dependence or of personality traits, which in turn might be associated with major depression.

Indications for management and referral of patients involved in substance abuse. American Academy of Pediatrics. Committee on Substance Abuse

This statement addresses the challenge of evaluating and managing the various stages of substance use by children and adolescents in the context of pediatric practice. Approaches are suggested that would assist the pediatrician in differentiating highly prevalent experimental and occasional use from more severe use with adverse consequences that affect emotional, behavioral, educational, or physical health. Comorbid psychiatric conditions are common and should be evaluated and treated simultaneously by child and adolescent mental health specialists. Guidelines for referral based on severity of involvement using established patient treatment-matching criteria are outlined. Pediatricians need to become familiar with treatment professionals and facilities in their communities and to ensure that treatment for adolescent patients is appropriate based on their developmental, psychosocial, medical, and mental health needs. The family should be encouraged to participate actively in the treatment process.

Determinants of attrition from cessation treatment in smokers with a history of major depressive disorder

Attrition from smoking cessation treatment by individuals with a history of major depression was investigated. An investigation of preinclusion attrition examined differences between eligible smokers who did (n = 258) and did not (n = 100) attend an initial assessment session. Postinclusion attrition was investigated by comparing early dropouts (n = 33), late dropouts (n = 27), and treatment completers (n = 117).

Early-treatment dropouts reported a higher smoking rate than late-treatment dropouts and endorsed more symptoms of depression than late dropouts and treatment completers. Results are compared with previous investigations of smoking cessation attrition, and implications for treatment and attrition prevention are discussed.

A review of tobacco smoking in adolescents: treatment implications

OBJECTIVE

To review current data on the tobacco epidemic in adolescents that impact treatment decisions.

METHOD

Epidemiological and pharmacological data, risk factors, characteristics of nicotine use in adolescents, and treatment intervention reports from the literature are discussed.

RESULTS

Of students in grades 9 to 12, 42.7% have used tobacco; 75% of teenage smokers will smoke as adults. Environmental and biological factors influence adolescent smoking, including sociodevelopmental aspects of adolescence, psychiatric history, genetic background, ethnic and gender characteristics, drug effects, and regulatory factors. Criteria for nicotine dependence are currently based on the experience with adult smokers. Overall, smoking cessation treatment for adolescents has been disappointing because of low participation, high attrition, and low quit rates.

CONCLUSION

Characterization of nicotine dependence and further assessment of the safety and efficacy of pharmacological treatment interventions in adolescents are needed given the formidable challenge of the tobacco epidemic in adolescents.

Initial tobacco use episodes in children and adolescents: current knowledge, future directions

Approximately three-quarters of adult tobacco users report that their first tobacco use occurred between ages 11 and 17, while many adults who do not regularly use tobacco report that they experimented with it as adolescents. Surprisingly little is known about the effects of these initial tobacco use episodes and their influence on adult tobacco use patterns. In particular, understanding the role that nicotine plays in these early tobacco use experiences may be important in understanding the development of regular tobacco use and concomitant nicotine dependence. One goal of this review is to summarize current knowledge regarding the effects of initial tobacco use episodes in adolescents and to discuss nicotine exposure in initial tobacco use episodes. Another goal is to outline a research agenda designed to learn more about initial tobacco use episodes and the effects of nicotine in children. An ethical rationale and some potential methods for this research agenda are presented.

Cigarettes and suicide: a prospective study of 50,000 men

OBJECTIVES

This study examined the relation between smoking and suicide, controlling for various confounders.

METHODS

More than 50,000 predominantly White, middle-aged and elderly male health professionals were followed up prospectively with biennial questionnaires from 1986 through 1994. The primary end point was suicide. Characteristics controlled for included age, marital status, body mass index, physical activity, alcohol intake, coffee consumption, and history of cancer.

RESULTS

Eighty-two members of the cohort committed suicide during the 8-year follow-up period. In age-adjusted analyses with never smokers as the comparison group, the relative risk of suicide was 1.4 (95% confidence interval [CI] = 0.8, 2.3) among former smokers, 2.6 (95% CI = 0.9, 7.5) for light smokers (< 15 cigarettes/day), and 4.5 (95% CI = 2.3, 8.8) among heavier smokers. After adjustment for potential confounders, the relative risks were 1.4 (95% CI = 0.9, 2.4), 2.5 (95% CI = 0.9, 7.3), and 4.3 (95% CI = 2.2, 8.5), respectively.

CONCLUSION

We found a positive, dose-related association between smoking and suicide among White men. Although inference about causality is not justified, our findings indicate that the smoking-suicide connection is not entirely due to the greater tendency among smokers to be unmarried, to be sedentary, to drink heavily, or to develop cancers.

Does smoking cessation improve mental health?

There is a possibility that cessation of smoking improves mental health, but there are no studies that have demonstrated this. A cohort study was performed for 1 year in 18 males who spontaneously stopped smoking (cessation group) and 173 who continued to smoke (smoking group). The mental health state was evaluated using the Japanese version of the 30-item General Health Questionnaire (GHQ-30) before the cessation of smoking and 6 months and 1 year after smoking cessation. Changes in the GHQ score were compared between the cessation and smoking groups. In order to control the effects of confounding factors, multiple regression analyses were performed using the GHQ score after 6 months and 1 year as dependent variables. The GHQ score in the cessation group significantly decreased 6 months and 1 year after smoking cessation (P < 0.04 and 0.01, respectively, by paired t-test). In the smoking group, the GHQ score slightly decreased. Repeated measure analysis of variance revealed that the decrease in the GHQ score in the cessation group was significantly larger than in the smoking group. Multiple regression analysis revealed significant effects of smoking cessation on mental health after controlling for other confounding factors. It can be concluded that smoking cessation may improve mental health.

Smoking and schizophrenia: abnormal nicotinic receptor expression

Biological and genetic evidence suggests a role for the neuronal nicotinic receptors in the neuropathophysiology of schizophrenia. Nicotine normalizes an auditory evoked potential deficit seen in subjects who suffer from the disease. Nicotinic receptors with both high and low affinity for nicotine are decreased in postmortem brain of schizophrenics compared to control subjects. The chromosomal locus of the human alpha-7 gene (15q14) is linked to the gating deficit with a lod of 5.3, and antagonists of the alpha-7 receptor (alpha-bungarotoxin and methyllycaconitine) induce a loss of gating in rodents. We have cloned the human alpha-7 gene and found it to be partially duplicated proximal to the full-length gene. The duplication is expressed in both the brain and in peripheral blood cells of normal subjects, but is missing in some schizophrenic subjects. The results of these studies suggest the presence of abnormal expression and function of the neuronal nicotinic receptor gene family in schizophrenia.

Are social fears and DSM-IV social anxiety disorder associated with smoking and nicotine dependence in adolescents and young adults?

To investigate associations between social anxiety and smoking behaviour in order to explore whether social anxiety predicts the first onset of cigarette smoking, regular smoking and the development of nicotine dependence. Baseline and four-year follow-up data from the Early Developmental Stages of Psychopathology Study (EDSP), a prospective-longitudinal community study of 3,021 adolescents and young adults, are used. Smoking behaviour and psychopathology were assessed with the M-CIDI and its DSM-IV algorithms. At baseline, 35.7% of the sample were regular smokers, and 18.7% fulfilled criteria for DSM-IV nicotine dependence. Twenty-seven point two percent reported at least one social fear, and 7.2% met criteria for DSM-IV social phobia, most of whom reported first onset of social fear problems clearly prior to smoking initiation. Cross-sectional retrospective baseline analyses based on retrospective reports revealed that social fears and DSM-IV social phobia were both significantly associated with higher rates of nicotine dependence. Prospective-longitudinal analyses that were conducted in an attempt to confirm cross-sectional retrospective results showed that baseline non-users with social fears (OR = 3.85) and baseline non-dependent users with social fears (OR = 1.5) had an increased risk of onset of nicotine dependence during the follow-up period of four years. These findings remained significant even when controlling for co-morbid depressive disorders. Social anxiety was found to be significantly associated with nicotine dependence in both cross-sectional retrospective and prospective-longitudinal analyses. It is suggested that social fears could lead to heavy tobacco use as smoking is a socially acceptable behaviour that relieves anxiety in social situations. Possible differential effects of social anxiety on the early stages of smoking behaviour compared to effects on nicotine dependence are discussed. These findings should stimulate a continued search into potentially causal links between social fear symptoms and the development of tobacco consumption and nicotine dependence in adolescence.

Antidepressant effect of ingested nicotine in female rats of Flinders resistant and sensitive lines

Both major depression and depressive symptoms are associated with a high rate of nicotine dependence, and a history of major depression has an adverse impact on smoking cessation. The main objective of this study was to investigate whether continuous ingestion of nicotine affects indices of depressive behavior in the rat. We compared cholinergic- and serotonergic-hypersensitive Flinders Sensitive Line rats (FSL), a genetic animal model of depression, with their control counterparts, Flinders Resistant Line rats (FRL). Female rats of both lines were allowed access to a solution of nicotine bitartrate (100 microg/mL) in tap water for 14 days. Subsequent behavioral testing revealed striking effects of continuous ingestion of nicotine on depressive-like behavior of both lines. FSL and FRL rats that ingested nicotine for 14 days displayed less immobility in the 10-min forced-swim test (an index of depressive-like behavior) relative to the animals of both lines that were not exposed to nicotine or exposed to nicotine for shorter periods of time. This finding indicates that ingested nicotine has antidepressant properties that are independent of the genetic difference between FSL and FRL female rats. Animal studies on nicotine ingestion and withdrawal may become an important source of insights into the comorbidity of depression and nicotine self-administration.

Adolescent tobacco use and cessation

Over one third of high school students in the United States smoke cigarettes, and close to 10% use spit tobacco. Tobacco use clusters with alcohol use, other substance abuse, and other health risk behaviors among teenagers. Public health and law enforcement policy changes, combined with effective substance use prevention programs in both elementary and middle school, are needed to prevent the early age of onset of tobacco use by youth. Primary care providers can play a key role in identifying children and adolescents who smoke or use spit tobacco and helping them discontinue their tobacco use.

Psychiatric comorbidity with substance misuse in children and teenagers

Substance misuse in children and young people is frequently associated with emotional and behavioural disorder not attributable directly to the effects of the substance. Such comorbid disorders include depression, suicidal behaviour, conduct disorder, attention deficit hyperactivity disorder, eating disorders, and psychosis. Some indication of causal links in specific samples has been found but there is not overall agreement. The heterogeneity of young people with comorbidity for psychiatric disorder and substance misuse suggest that some would better be considered as multiproblem children for whom the necessary conditions are vulnerability, lack of family protection and exposure to a source of drugs. Children who present with comorbidity are at very high risk. This may be reduced by early identification and treatment of the comorbid condition and vigilance for substance misuse in all cases. Development of specific services for young substance misusers, coordinating efforts from Health Social Services and Education is merited in view high risk for future physical and psychiatric disorder. Few such services currently exist in the UK.

Relationship of ADHD, depression, and non-tobacco substance use disorders to nicotine dependence in substance-dependent delinquents

This study used standardized interviews to examine the relationship of attention deficit hyperactivity disorder (ADHD), major depression (MDD), and other illicit substance use disorders (SUD) to onset and severity of nicotine dependence in 82 female and 285 male adolescents with conduct disorder (CD) and SUD. Results indicate that both ADHD and MDD significantly contribute to severity of nicotine dependence in delinquents with SUD. ADHD is further associated with earlier onset of regular smoking in males. Severity of non-tobacco SUD also was related directly to nicotine dependence severity in both males and females, and to earlier onset of smoking in males. Our findings illuminate the contribution of comorbidity to nicotine dependence and its relationship to other SUD severity among adolescents with CD and SUD and highlight the need for coordinated assessment and treatment of smoking cessation along with concurrent treatment of other drug use and psychiatric comorbidity such as ADHD and MDD in such youths.

Depression, anxiety, and smoking initiation: a prospective study over 3 years

OBJECTIVES

This report considers the extent to which depression and anxiety predict smoking onset in adolescence.

METHODS

A 6-wave cohort design was used to study a sample of 14- and 15-year-old students (n = 2032) drawn from 44 secondary schools in the state of Victoria, Australia. The students were surveyed between 1992 and 1995 with a computerized questionnaire that included a 7-day retrospective diary for tobacco use and a structured psychiatric interview.

RESULTS

Experimental smokers were 29 times more likely than non-smokers to make a transition into daily use in the subsequent 6 months. Depression and anxiety, along with peer smoking, predicted initiation of experimental smoking. Specifically, depression and anxiety accentuated risks associated with peer smoking and predicted experimentation only in the presence of peer smoking.

CONCLUSIONS

The finding that experimental smoking is an overwhelmingly strong predictor of later daily smoking focuses attention on smoking initiation. Depressive and anxiety symptoms are associated with higher risks for initiation through an increased susceptibility to peer smoking influences. Promoting the psychological well-being of adolescents and addressing perceived interpersonal benefits of smoking may play a role in the prevention of adolescent tobacco use.

Practice parameters for the assessment and treatment of children and adolescents with depressive disorders. AACAP

Child and adolescent major depressive disorder and dysthymic disorder are common, chronic, familial, and recurrent conditions that usually persist into adulthood. These disorders appear to be manifesting at an earlier age in successive cohorts and are usually accompanied by comorbid psychiatric disorders, increased risk for suicide, substance abuse, and behavior problems. In addition, depressed youth frequently have poor psychosocial, academic, and family functioning, which highlights the importance of early identification and prompt treatment. Both psychotherapy and pharmacotherapy have been found to be beneficial for the acute treatment of youth with depressive disorders. Opinions vary regarding which of these treatments should be offered first and whether they should be offered in combination. In general, the choice of initial therapy depends on clinical and psychosocial factors and therapist's expertise. Based on the current literature and clinical experience, psychotherapy may be the first treatment for most depressed youth. However, antidepressants must be considered for those patients with psychosis, bipolar depression, severe depressions, and those who do not respond to an adequate trial of psychotherapy. All patients need continuation therapy and some patients may require maintenance treatment. Further research is needed on the etiology of depression; the efficacy of different types of psychotherapy; the differential effects of psychotherapy, pharmacotherapy, and integrated therapies; the continuation and maintenance treatment phases; treatment for dysthymia, treatment-resistant depression, and other subtypes of major depressive disorder; and preventive strategies for high-risk children and adolescents.

Child and adolescent psychopharmacology. Important developmental issues

This article begins with an overview of developmental variations in pharmacokinetics and pharmacodynamics and then discusses issues related to decision making before beginning treatment with medication, including diagnosis, impairment, and consent. Subsequently, specific disorders, such as attention deficit hyperactivity disorder, mood disorders, and obsessive-compulsive disorder, are briefly discussed, with focus on issues relevant to a developmental approach to pediatric psychopharmacology.

Factors associated with smoking among children and adolescents in Connecticut

INTRODUCTION

The age of smoking initiation has dropped over the past four decades. Since behaviors and attitudes adopted in late childhood or early adolescence predict future smoking, it is important to understand the smoking and other risk-taking behaviors and attitudes of children aged 12 and younger. The goal of the analyses presented here was to describe behavioral and attitudinal factors associated with smoking among elementary school (grades 4-6), middle school (grade 7-8), and high school (grades 9-12) students in Connecticut.

METHODS

We have used data from 8 years (1988-1996) of an anonymous, self-administered health risk appraisal survey given to children and adolescents in self-selected public and private schools. We compared the proportion of smokers and nonsmokers who reported various behaviors and attitudes and compared them with the chi-square test.

RESULTS

Fifteen percent (n = 4,884) of the total population (n = 31, 861) were current smokers. At all grade levels, current smokers were more likely than nonsmokers to engage in risk-taking behaviors, and to report more stress and depression. Indicators of risk-taking and stress were also associated with the intent to smoke among children in grades 4-6.

CONCLUSIONS

Smoking occurs within the context of other risk-taking behavior and psychological distress, among both children and older adolescents. Our data provide support for the idea of early identification and targeting of children at high risk of smoking in elementary school, possibly as early as grade four.

Teenagers: mental health and psychological issues

Adolescence is a developmental period marked by multiple challenges and demands which create a heightened vulnerability to the development of emotional disorders. Primary care physicians are in an ideal position to intervene in the early stages and prevent the tragic consequences which can occur with an untreated mental health disorder. This article reviews the assessment and treatment of adolescent mental health in the primary care medical setting. Knowledge of these disorders and their manifestations in the primary care environment will enable clinicians to provide higher quality medical care and will reduce the potential for continual life disruptions into the adult years.

Adolescent depression. Epidemiology, nosology, life stress and social network. Minireview based on a doctoral thesis

The study engaged a total population of 16-17-year-old urban high-school students and 2300 (93%) were screened for depression and previous suicide attempts. Adolescents with high depression scores in self-evaluation (12.3%) or reporting previous suicide attempts (2.4%) were diagnostically interviewed together with one control for each, matched for gender and educational program. After the interview self-ratings were completed regarding social network, family climate, and life events. Major depression was prevalent during the last year in 5.8% and during life time in 11.4%, 4 girls for every boy. A depression with remaining symptoms for a year or more was the most common type. Dysthymia without major depressive episodes was diagnosed in 1.1%, two girls for every boy. Short hypomanic episodes had been experienced by 13.2% of those with major depressive disorder. Anxiety disorder was comorbid to depression in one half and conduct disorder in one forth of the depressed adolescents. Alcohol was abused by 6.5% and used regularly by another 12%. Other drugs were used by 6.5% of depressed adolescents and not at all by controls. The depressed used tobacco twice as frequently as non-depressed. Social network and family climate were compared within the originally matched pairs. Adolescents with long-lasting depressions had a smaller and unsatisfying social network. They also had experienced many stressful life events related to family adversities, while those with shorter depressive episodes had stress related to the peer group. Depressed adolescents with comorbid conduct disorder reported insufficient support from the close network and a more negative family climate.
