Metabolic syndrome among young adults at high and low familial risk for depression.

BACKGROUND: Our study examined whether the early-onset depression phenotype among young adults (probands) is associated with the metabolic syndrome (MetS) and its components, and if MetS characterizes unaffected but high-risk siblings of probands. METHODS: We studied three groups of young adults (Mage = 25 years, s.d. = 3.84 years): probands with histories of childhood onset depression - i.e. early-onset phenotype - (n = 293), their unaffected siblings (high-risk siblings, n = 273), and healthy controls (n = 171). Participants completed a full psychiatric interview, physical and laboratory assessments, and self-rating scales. MetS was defined using the criteria of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (). RESULTS: Early-onset depression phenotype and being a high-risk sibling were associated with higher MetS composite scores relative to that of controls, but did not differ from one another. With regard to MetS components: Probands and siblings had similarly larger waist circumference and lower HDL than did controls, while siblings and controls had lower triglyceride levels than did probands but did not differ from one another. Groups did not differ on glucose levels and SBP. CONCLUSIONS: Our study extends the literature on the association between MetS and depression and underscores the importance of depression phenotypes: failure to account for the clinical heterogeneity of depression may partly underlie the inconsistent findings regarding its relation to MetS. The results also suggest that, in depression-prone populations, MetS may predate and possibly function as a risk factor for eventual depression.

[Psychometric properties of the Hungarian Adult Attachment Scale]. / A Collins­Read Felnott Kötodési Skála pszichometriai jellemzoinek vizsgálata.

BACKGROUND AND PURPOSE: The revised Adult Attachment Scale (AAS) developed by N. L. Collins is a widely used questionnaire to measure adult attachment. However, its psychometric properties have not been investigated in Hungary. We aimed to confirm the key psychometric properties of the Hungarian version of the AAS focusing on reliability indices on a population that consis-ted of depressed and non-depressed young adults. METHODS: The AAS is a self-report questionnaire, in which two different dimensional evaluating systems are possible: the original (close, depend, and anxiety) and the alternative scoring system (anxiety, avoidance). Our study population consisted of young adults with a history of major depression (n = 264, median age = 25.7 years) and their never-depressed biological siblings (n = 244, median age = 24.0). RESULTS: The internal consistency of close, anxiety, and avoidance scales were satisfactory (Cronbach-α >0.7). The consistency of the depend scale was slightly lower than expected (Cronbach-α = 0.62). Test-retest reliability was good for all of the scales, it ranged from 0.73 to 0.78 after 14 months of follow-up period. The scale showed good discrimination as tested by the differences of close and anxiety attachment dimensions between the groups (p<0.01). More-over, we were able to differentiate the currently dep-res-sed subjects based on these attachment dimensions. Explo-ra-tory and confirmatory factor analyses were conducted, and a bifactor solution proved optimal model fit. CONCLUSION: The three dimensions of the AAS has not been confirmed. However, the close and anxiety scales of AAS were found to be adequate. Our results also indicate that attachment features correlate with major depressive episodes in adulthood.

["Risk factors of childhood depression" research grant - past, present, future].

The authors summarize the last 10 years of an ongoing collaborative study between the Universities of Szeged and Pittsburgh on early onset major depression. First, the "Risk factors of childhood depression" grant is presented briefly as an initial research study in which the subjects of the current studies were recruited. This is a prominently large clinical sample in the field of child psychiatry even on an international level. In addition to the follow-up of the prognosis of the disorder, recent studies continue to explore the early onset depression in two directions. On the one hand, two studies investigate the role of biobehavioral inflexibility markers in the development of major depression ("Biobehavioral inflexibility and risk for juvenile-onset depression" and "Biobehavioral inflexibility and risk for juvenile-onset depression - renewal grant"). On the other hand, the authors would like to have a better understanding of the possible relationship between the major depression and cardiovascular diseases ("Pediatric depression and subsequent cardiac risk factors: a longitudinal study"). The most significant aims of the three studies will be demonstrated, as well as how the studies were prepared and organized along with the already existing experience concerning research management and involvement of new collaborating partners and experts.

[Long-term follow-up of childhood-onset depression - comorbidity, suicidal behavior and prognosis in adulthood].

INTRODUCTION: Several long-term follow-up studies investigate the progression of adolescent onset major depressive disorder but much less explore short and long-term consequences and prognosis into adulthood of childhood- onset depression. The aim of the present study is to follow childhood-onset depression, lifetime comorbid psychiatric disorders and suicidal behavior into adulthood. METHODS: Subjects (N=166) were 25.95+2.42 years old on average, 54.2% were women. Follow-up period lasted for a mean of 14.74+1.31 years. Psychiatric diagnosis was assessed by a DSM-IV based semi-structured interview. Subjects reported on 4 stages of suicidal behavior as one of the symptoms of depressive disorder. RESULTS: The onset of the first depressive episode was at the mean age of 10.17+2.34 years. 40,4% of the sample had only 1 episode while recurrent depressive episode presented in 32.5% above 18 years of age. Lifetime comorbid psychiatric disorders were present in more than 1/3 of the sample. The most frequent lifetime comorbidity was anxiety (42.4%), and specific phobia among anxiety disorders. Lifetime attention deficit-hyperactivity disorder and oppositional/conduct disorder were also frequent (25.9% and 16.9%, respectively). Suicidal behavior was not present life-time in 19.1% of the sample. Thoughts of death and thoughts of suicide were quite frequent (80.8% and 69.5%, respectively), specific plans and suicidal attempt were more frequent in girls (plan:female vs male 53.9% vs 38.4%, attempt: 33.3% vs 9.6%) during follow-up. CONCLUSION: About one-third of childhood-onset depression had recurrence above 18 years of age, which is lower than the recurrence rate for adolescent onset depression. A high rate of lifetime comorbidity was found between depression and anxiety disorders. The assessment of the actual level of suicidal behavior is important in the prevention of selfdestructive behavior.

Emotion Regulation Among Adolescents With Pediatric Depression As a Function of Anxiety Comorbidity.

Background: Both depression and anxiety (two of the most common internalizing psychopathologies among youths) are associated with difficulties in emotion regulation (ER). Little is known about whether anxiety as a comorbid condition has an effect on the habitual use of different ER strategies in youngsters with depression histories. We aimed 1) to compare ER in adolescents with histories of childhood onset major depressive disorder (MDD) with and without comorbid anxiety and 2) to examine whether certain ER response clusters (Cognitive, Social, and Behavioral/Physical) characterize comorbid children and adolescents. Methods: We analyzed data on 217 youth (11-18 years old) with depression history: 85 subjects with lifetime anxiety comorbidity (comorbid group) and 132 without lifetime anxiety (non-comorbid group). Psychiatric diagnosis was established by a comprehensive Diagnostic and Statistical Manual of Mental Disorders (DSM) IV-based diagnostic procedure. ER strategies were examined via the self-rated "Feelings and Me" Child version questionnaire (FAM-C). Results: The comorbid group used maladaptive ER strategies significantly more frequently than the non-comorbid youngsters. The Behavioral/Physical and Social ER skills, especially those reflecting social withdrawal and self-harm, were responsible for the higher maladaptive scores. Limitations: Because our study is a cross-sectional analysis, we have no information about the development or the onset of maladaptive ER strategies. Therefore, we were unable to examine whether maladaptive ER was a risk factor or a consequence of the internalizing psychopathology and comorbidity. Conclusions: Comorbid anxiety worsens the impaired use of ER strategies in depression-prone youths. Further longitudinal research is needed to explore the causal role of dysfunctional ER in the development of internalizing psychopathology.

Autonomic correlates of lifetime suicidal thoughts and behaviors among adolescents with a history of depression.

Suicidal thoughts and behaviors (STBs) have been associated with emotion dysregulation and atypical responses to affective and stressful stimuli. To investigate the psychophysiology involved, we measured changes in respiratory sinus arrhythmia (RSA) and cardiac pre-ejection period (PEP; indexing parasympathetic and sympathetic functioning, respectively) in response to stressful- and sadness-eliciting laboratory probes. Our sample included adolescents with a history of depression and STBs (n = 177), adolescents with a history of depression but no history of STBs (n = 47), and healthy controls (n = 175). The outcome of interest was the most severe form of clinician-rated STBs across the subject's lifetime. In partial support of our hypotheses, during the stressful task, adolescents with a history of depression and STBs did not evidence the RSA decrease that was exhibited by controls and displayed greater PEP shortening compared to ever-depressed adolescents with no lifetime STBs. No group differences were found in either RSA or PEP reactivity to the sadness-eliciting stimulus. As expected, severity of STBs was positively correlated with the extent of PEP shortening during the stressful task. The results suggest that adolescents with a history of depression and STBs experience blunted parasympathetic responses to stress along with compensatory efforts. Our findings contribute to a better understanding of STBs among youths and underscore that future studies should examine physiological risk factors for these psychopathological outcomes.

Dysregulated behavioral responses to hedonic probes among youth with depression histories and their high-risk siblings.

Affect dysregulation in response to rewarding stimuli has been proposed as a vulnerability factor for major depressive disorder (MDD). However, it remains unclear how affective behavioral dynamics may be altered among individuals who are at high risk for depression but not currently depressed. We examined the dynamics of affective facial behavior during hedonic probes among 3 groups of adolescents: remitted probands who had histories of childhood-onset MDD (n = 187), never-depressed siblings of probands (high familial risk; n = 207), and healthy controls (n = 166). Participants' happy and sad facial expressions were coded during 3 hedonic laboratory tasks: receiving a preferred prize, describing a positive autobiographical memory, and watching a humorous film. Happy and sad behavioral dynamics were indexed by mean level- and time-dependent reactivity, variability (mean of the squared successive differences), and inertia (autocorrelation). Relative to controls, probands and siblings exhibited a more rapid decrease in happy behaviors, and probands exhibited higher inertia of sad behaviors during hedonic probes. Both probands and siblings exhibited lower inertia of sad behaviors while receiving a desired prize, which highlights the importance of context variation in testing hypotheses. Overall, our study provides new evidence that hedonic behavioral dysregulation, as reflected in dynamic facial behavior, may highlight depression vulnerability.

Effect of maternal depression and anxiety on mother's perception of child and the protective role of social support.

OBJECTIVE: The purpose of this study was to investigate the impact of postpartum depressive and anxiety symptoms on maternal perception of the infant and the protective role of social support. BACKGROUND: Adverse effects of perinatal depression on mother-child interaction are well documented; however, the role of maternal perception has not been examined. METHODS: We used the data of 431 women enrolled in a prospective study in a single maternity unit. Depressive and anxiety symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS), the State Trait Anxiety Inventory (STAI), and the mother's perception of infant with the Mother's Object Relation Scale (MORS). We used Multidimensional Scale of Perceived Social Support (MSPSS) in order to measure social support. RESULTS: Depressive and anxiety symptoms were positively associated to less positive emotions and a more dominant attitude of child as perceived by mothers. This association was even more significant in the case of trait anxiety. Perceived social support has been found to be a protective factor which was able to reduce this tendency. CONCLUSION: The findings have potential implications for our understanding of the impact of maternal depressive and anxiety symptoms on the developing mother-infant relationship.

Relevance of anxiety in the perinatal period: prospective study in a Hungarian sample.

There is increasing evidence that anxiety occurs frequently during pregnancy and can be one of the most important risk factors and predictors of postpartum depression (PPD). The aim of our study was to investigate whether antenatal anxiety is an independent predictor of PPD. We used the data of 476 women enrolled in a prospective study in a single maternity unit. The first assessment was conducted between 22 and 40 weeks gestation and a second time 8-12 months postpartum. Symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) and the State Trait Anxiety Inventory (STAI). Based on our results, antenatal anxiety measured by a subscale of EPDS has predicted better PPD than the antenatal depressive subscale. However, the most relevant predictor of PPD might be the trait anxiety level of a women measured by STAI Trait Scale, whereas a cutoff value of 38 was identified to indicate higher risk of PPD.

Childhood adversity predicts reduced physiological flexibility during the processing of negative affect among adolescents with major depression histories.

BACKGROUND: Adversity during early development has been shown to have enduring negative physiological consequences. In turn, atypical physiological functioning has been associated with maladaptive processing of negative affect, including its regulation. The present study therefore explored whether exposure to adverse life events in childhood predicted maladaptive (less flexible) parasympathetic nervous system functioning during the processing of negative affect among adolescents with depression histories. METHODS: An initially clinic-referred, pediatric sample (N=189) was assessed at two time points. At Time 1, when subjects were 10.17years old (SD=1.42), on average, and were depressed, parents reported on adverse life events the offspring experienced up to that point. At Time 2, when subjects were 17.18years old (SD=1.28), and were remitted from depression, parents again reported on adverse life events in their offspring's lives for the interim period. At time 2, subjects' parasympathetic nervous system functioning (quantified as respiratory sinus arrhythmia) also was assessed at rest, during sad mood induction, and during instructed mood repair. RESULTS: Extent of adverse life events experienced by T1 (but not events occurring between T1 and T2) predicted less flexible RSA functioning 7years later during the processing of negative affect. Adolescents with more extensive early life adversities exhibited less vagal withdrawal following negative mood induction and tended to show less physiological recovery following mood repair. CONCLUSIONS: Early adversities appear to be associated with less flexible physiological regulatory control during negative affect experience, when measured later in development. Stress-related autonomic dysfunction in vulnerable youths may contribute to the unfavorable clinical prognosis associated with juvenile-onset depression.

Positive autobiographical memory deficits in youth with depression histories and their never-depressed siblings.

OBJECTIVES: Impaired positive autobiographical memory (AM) is closely linked to emotional disorders. AM impairments are often found in depressed adults and may be related to the difficulties such persons have in regulating their dysphoric mood. By contrast, less is known about AM disturbances among adolescents, or about the functional relationship of AM disturbances to early-onset depression. DESIGN: A high-risk family design served to compare four groups of youth who differed in depression histories and familial depression risk. METHODS: Thirty-one currently depressed probands, 185 remitted probands, 204 never-depressed siblings of probands, and 180 healthy control youth were induced into a negative mood prior to recalling positive AMs via a novel memory elicitation procedure. Several positive AM characteristics were assessed. RESULTS: Relative to control youth, unaffected siblings and probands exhibited consistently impaired positive AMs. Moreover, we also found some evidence that probands were more impaired than siblings, who were in turn more impaired than controls, consistent with a gradient effect. CONCLUSIONS: Positive AM disturbances may not only precede the onset of depression in vulnerable youth, but also continue to persist after remission of a depressive episode. Clinical and basic research implications of the findings are discussed. PRACTITIONER POINTS: Positive AM impairments may be trait-like, persist in the euthymic phase of depression, and may serve as a risk marker for early-onset depression among vulnerable adolescents. Disturbances in positive AM may negatively impact the mood-regulatory functions of positive memory recall and contribute to persistent sadness and anhedonia, which are core features of depression. Our sample of currently depressed youth was relatively small, tempering our conclusions. Although we collected data on some important covariates (e.g., socioeconomic status), we lacked information on other relevant variables such as youths' executive functioning or IQ.

Positive Affectivity is Dampened in Youths with Histories of Major Depression and Their Never-Depressed Adolescent Siblings.

While hedonic capacity is diminished during clinical depression, it is unclear whether that deficit constitutes a risk factor and/or persists after depression episodes remit. To examine these issues, adolescents with current/past major depression (probands; n=218), never depressed biological siblings of probands (n=207), and emotionally-well controls (n=183) were exposed to several positively valenced probes. Across baseline and hedonic probe conditions, controls consistently reported higher levels of positive affect than high-risk siblings, and siblings reported higher levels of positive affect than probands (remitted and depressed probands' reports were similar). Extent of positive affect across the protocol predicted adolescents' self-reports of social support network and parental reports of offspring's use of various adaptive mood repair responses in daily life. Attenuated hedonic responding among youths remitted from depression offers partial support for anhedonia as a trait, while its presence among never depressed high-risk siblings argues for anhedonia as a potential diathesis for clinical depression.

Parasympathetic nervous system activity predicts mood repair use and its effectiveness among adolescents with and without histories of major depression.

Depressive disorders that onset in the juvenile years have been linked to far-reaching adverse consequences, making it imperative to elucidate key mechanisms and contributory factors. Excessive use of regulatory responses that exacerbate sadness (maladaptive mood repair) or insufficient use of regulatory responses that reduce it (adaptive mood repair) may reflect behavioral mechanisms of depression risk. Cardiac vagal control, indexed by patterns of respiratory sinus arrhythmia (RSA), has received attention as a putative physiological risk factor for depression. Although mood repair and RSA are related, the nature of this relationship is not well characterized in the context of depression risk. Therefore, we tested alternative models of the relationships between RSA patterns (at rest and in response to a sad film), trait mood repair, and the effectiveness of a mood repair response in the laboratory (state mood repair) among adolescents with depression histories (n = 210) and emotionally healthy peers (n = 161). In our data, a mediation model best explained the association between the key constructs: Adolescents with normative RSA patterns exhibited lower levels of depression and trait maladaptive mood repair, and benefited more from instructed (state) mood repair in the laboratory. By contrast, adolescents with atypical RSA patterns exhibited higher levels of depression and dispositional maladaptive mood repair, which, in turn, mediated the relations of RSA patterns and depression symptoms. Atypical RSA patterns also predicted reduced benefits from laboratory mood repair.

[Psychosocial aspects of preeclampsia]. / A praeeclampsia pszichoszociális vonatkozásai.

Distress conditions during pregnancy may contribute to the development of preeclampsia by altering functions of the neuroendocrine and immune systems, e.g. activation of the hypothalamic-pituitary-adrenal axis and increase in plasma proinflammatory cytokines. Preeclampsia may also precipitate mental health problems due to long-term hospitalization or unpredictable and uncontrollable events such as preterm labor and newborn complications. Besides, preeclampsia may induce persistent neurocognitive complaints with a negative impact on patients' quality of life. As growing evidence indicates that poor maternal mental health has an adverse effect on pregnancy outcome and fetal development, psychosocial interventions may be beneficial for women with preeclampsia.

BDNF Val66Met polymorphism and stressful life events in melancholic childhood-onset depression.

INTRODUCTION: Brain-derived neurotrophic factor (BDNF) polymorphisms have been examined for their contribution toward depression with equivocal results. More homogeneous phenotypes might be used to improve our understanding of genetic liability to depression. The aim of our study was to (a) test for an association between the BDNF Val66Met polymorphism and childhood-onset melancholic depression and (b) to examine the interactive effects of stressful life events (SLE) and the Val66Met polymorphism on the risk of childhood-onset melancholic depression. MATERIALS AND METHODS: A total of 583 depressed probands were involved in this study (162 of the melancholic subtype). Diagnoses were derived through the Interview Schedule for Children and Adolescents - Diagnostic Version and life event data were collected using an Intake General Information Sheet. RESULTS: Overall, 27.8% of the participants fulfilled the criteria for melancholy. In the melancholic group, the proportion of females was higher (53.1%), although there were more males in the overall depressed sample. We detected no significant differences in genotype or allele frequency between the melancholic and the nonmelancholic depressed group. The BDNF Val66Met polymorphism and SLE interaction was not significantly associated with the melancholy outcome. CONCLUSION: In our study, females were more prone to developing the early-onset melancholic phenotype. To our knowledge, this is the first study to investigate the differentiating effect of the genotype and the G×E interaction on the melancholic phenotype in a large sample of depressed young patients. We did not find an association between the melancholic subtype of major depression and the BDNF genotype and SLE interaction in this sample, which is representative of the Hungarian clinic-referred population of depressed youths.

Juvenile onset depression alters cardiac autonomic balance in response to psychological and physical challenges.

Cardiac autonomic balance (CAB) indexes the ratio of parasympathetic to sympathetic activation (Berntson, Norman, Hawkley, & Cacioppo, 2008), and is believed to reflect overall autonomic flexibility in the face of environmental challenges. However, CAB has not been examined in depression. We examined changes in CAB and other physiological variables in 179 youth with a history of juvenile onset depression (JOD) and 161 healthy controls, in response to two psychological (unsolvable puzzle, sad film) and two physical (handgrip, and forehead cold pressor) challenges. In repeated measures analyses, controls showed expected reductions in CAB for both the handgrip and unsolvable puzzle, reflecting a shift to sympathetic relative to parasympathetic activation. By contrast, JOD youth showed increased CAB from baseline for both tasks (p's<.05). No effects were found for the forehead cold pressor or sad film tasks, suggesting that CAB differences may arise under conditions requiring greater attentional control or sustained effort.

Mood repair via attention refocusing or recall of positive autobiographical memories by adolescents with pediatric-onset major depression.

BACKGROUND: Impaired emotion regulation is increasingly recognized as a core feature of depressive disorders. Indeed, currently and previously depressed adults both report greater problems in attenuating sadness (mood repair) in daily life than healthy controls. In contrast, studies of various strategies to attenuate sad affect have mostly found that currently or previously depressed adults and controls were similarly successful at mood repair in the laboratory. But few studies have examined mood repair among depression-prone youths or the effects of trait characteristics on mood repair outcomes in the laboratory. METHODS: Adolescents, whose first episode of major depressive disorder (MDD) had onset at age 9, on average (probands), and were either in remission or depressed, and control peers, watched a sad film clip. Then, they were instructed to engage in refocusing attention (distraction) or recalling happy memories. Using affect ratings provided by the youths, we tested two developmentally informed hypotheses about whether the subject groups would be similarly able to attenuate sadness via the two mood repair strategies. We also explored if self-reported habitual (trait) mood repair influenced laboratory performance. RESULTS: Contrary to expectations, attention refocusing and recall of happy memories led to comparable mood benefits across subjects. Control adolescents reported significantly greater reductions in sadness than did depressed (Cohen's d = .48) or remitted (Cohen's d = .32) probands, regardless of mood repair strategy, while currently depressed probands remained the saddest after mood repair. Habitual mood repair styles moderated the effects of instructed (state) mood repair in the laboratory. CONCLUSIONS: Whether depressed or in remission, adolescents with MDD histories are not as efficient at mood repair in the laboratory as controls. But proband-control group differences in mood repair outcomes were modest in scope, suggesting that the abilities that subserve affect regulation have been preserved in probands to some degree. Further information about the nature of mood repair problems among youths with depression histories would help to better understand the clinical course of MDD and to design personalized interventions for depression.

The association between major depressive disorder in childhood and risk factors for cardiovascular disease in adolescence.

OBJECTIVE: Depression in adults is associated with risk factors for cardiovascular disease (CVD). It is unclear, however, when the association between clinical depression and cardiac risk factors develops or how early in life this association can be detected. METHODS: In an ongoing study of pediatric depression, we compared CVD risk factors including smoking, obesity, physical activity level, sedentary behavior, and parental history of CVD across three samples of adolescents: probands with established histories of childhood-onset major depressive disorder (n = 210), never-depressed siblings of probands (n = 195), and controls with no history of any major psychiatric disorder (n = 161). RESULTS: When assessed during adolescence, 85% of the probands were not in a major depressive episode. Nevertheless, at that assessment, probands had a higher prevalence of regular smoking (odds ratio [OR] = 12.54, 95% confidence interval [CI] = 4.36-36.12) and were less physically active than controls (OR = 0.59, CI = 0.43-0.81) and siblings (OR = 0.70, CI = 0.52-0.94) and had a higher rate of obesity than did controls (OR = 3.67, CI = 1.42-9.52). Parents of probands reported high rates of CVD (significantly higher than did parents of controls), including myocardial infarction and CVD-related hospitalization (ORs = 1.62-4.36, CIs = 1.03-15.40). Differences in CVD risk factors between probands and controls were independent of parental CVD. CONCLUSIONS: Major depression in childhood is associated with an unfavorable CVD risk profile in adolescence, and risks for pediatric depression and CVD may coincide in families. Effective prevention and treatment of childhood depression may be a means to reduce the incidence of adult CVD.

Impact of maternal depression on pregnancies and on early attachment.

The relatively high prevalence and duration of depression in the prenatal and postpartum periods reinforce the need for better understanding of maternal depression. The purpose of this article is to explore the main effects of depression to pregnancies' outcome and to early attachment reviewing research from the last decade and to find the best way to prevent the negative effects of maternal depression to infants. Recent studies have reported significant associations between maternal depression and several adverse obstetric, fetal, and neonatal outcomes. Antenatal depression has been associated with shorter gestation and lower birth weight, with consequences for infant development. A number of studies have demonstrated an association between prenatal depression and attachment difficulties, which seems to play an important mediating role in the development of further adverse outcomes for children. This review reveals some potential risks of untreated depression during the antenatal and postnatal periods, with possibly significant implications for practice and further research. Considering the high prevalence of depression, antenatal detection of depressive symptoms and intervention before childbirth has huge importance in prevention. Early interventions also may need to focus on mother-infant interactions as a key factor of later child development.

[Symptoms of depression in children and adolescents in relation to psychiatric comorbidities]. / A gyermek- és serdulokori depresszio tuneteinek összefuggése a pszichiatriai komorbiditásokkal.

INTRODUCTION: The lifetime prevalence of MDD before adolescence is 4-5%, while the symptoms concern 13-20% of the adolescents. In the development of suicidal behaviour the most important risk factors are the use of psychoactive drugs and smoking. Psychiatric comorbidities are aggravating significantly the major depression. The comorbidities are high among major depression, anxiety and disruptive disorders. SAMPLE AND METHOD: We examined 649 children being in a depressive episode diagnosed by ISCA-D semi-structured interview, 45,9% of them were girls, and 54,1% were boys, the mean age was 11,7 years ( SD=2,00). The participants were enrolled into three groups according to their comorbidities: group with only depression without comorbidities, group with anxiety comorbidity, and group with disruptive comorbidity. We compared the three groups according to the frequency of their depressive symptoms. RESULTS: Anxiety comorbidities increase the incidence of depressive symptoms. Among the criteria symptoms irritability where the most frequent symptom independently from the comorbidities, the depressed mood is the most frequent within the anxiety group, while anhedonia occurred with a moderate frequency in each groups. In the anxiety group the vegetative symptoms, while in the disruptive group the psychomotor agitation and the feeling of worthlessness are the most frequent symptoms. Comorbidities are increasing the incidence of the suicide symptoms. The incidence of impaired decision making was high in each group, the comorbidities didn't influence it's frequency. Among depressed boys irritability and feelings of worthlessness (low self-esteem) increase the presence of externalisation comorbidity. Among depressed girls guilt was significantly more frequent in the anxiety comorbidity group, and concentration problems are the most typical symptoms in the clear MDD group, without comorbidities.
