Hopelessness and depressive symptoms in children and adolescents: An integrative data analysis.

Although hopelessness has been linked to depression for centuries, the diagnostic criteria for depression are inconsistent with regard to the status of hopelessness. Most research on hopelessness and depression has focused on adults. The current study examined this relation in children and adolescents.

Salivary Cortisol Does Not Correlate with Metabolic Syndrome Markers or Subjective Stress in Overweight Children.

Objective: Being overweight is a risk factor for metabolic syndrome in children, but not all overweight children develop metabolic syndrome. Cortisol excess from chronic psychological stress has been proposed as an independent risk factor for metabolic syndrome in this already at-risk population. The present study assesses the relationship of biochemical and body composition radiographic markers of metabolic syndrome to salivary cortisol and self-report of chronic psychological stress in a cohort of overweight children.

Degree of anxiety in food allergic children in a tertiary care center.

Background: The link between internalizing psychiatric disorders, such as anxiety and depression, and allergic diseases has attracted a high level of interest from psychiatrists and immunologists. Recent studies have found increased anxiety in children with asthma, but findings in children with food allergy (FA) have been inconsistent.

Objective: It was hypothesized that children with FA would score significantly higher on a standardized anxiety screen than general pediatric (GP) patients but not as high as patients with diagnosed anxiety disorders.

Adolescent adrenocortical activity and adiposity: differences by sex and exposure to early maternal depression.

Prior research has linked either basal cortisol levels or stress-induced cortisol responses to adiposity; however, it remains to be determined whether these distinct cortisol measures exert joint or independent effects. Further, it is unclear how they interact with individual and environmental characteristics to predict adiposity. The present study aims to address whether morning cortisol levels and cortisol responses to a psychosocial stressor independently and/or interactively influence body mass index (BMI) in 218 adolescents (117 female) participating in a longitudinal community study, and whether associations are moderated by sex and exposure to early maternal depression.

Neurocognitive function and state cognitive stress appraisal predict cortisol reactivity to an acute psychosocial stressor in adolescents.

Stress and associated alterations in hypothalamic-pituitary-adrenal (HPA) function have deleterious influence on the development of multiple mental and physical health problems. Prior research has aimed to identify individuals most at risk for the development of these stress-related maladies by examining factors that may contribute to inter-individual differences in HPA responses to acute stress. The objectives of this study were to investigate, in adolescents, (1) whether differences in neurocognitive abilities influenced cortisol reactivity to an acute stressor, (2) whether internalizing psychiatric disorders influenced this relationship, and (3) whether acute cognitive stress-appraisal mechanisms mediated an association between neurocognitive function and cortisol reactivity.

Are increased weight and appetite useful indicators of depression in children and adolescents?

During childhood and adolescence, physiological, psychological, and behavioral processes strongly promote weight gain and increased appetite while also inhibiting weight loss and decreased appetite. The Diagnostic and Statistical Manual-IV (DSM-IV) treats both weight-gain/increased-appetite and weight-loss/decreased-appetite as symptoms of major depression during these developmental periods, despite the fact that one complements typical development and the other opposes it. To disentangle the developmental versus pathological correlates of weight and appetite disturbance in younger age groups, the current study examined symptoms of depression in an aggregated sample of 2307 children and adolescents, 47.

Influence of early life stress on later hypothalamic-pituitary-adrenal axis functioning and its covariation with mental health symptoms: a study of the allostatic process from childhood into adolescence.

The hypothalamic-pituitary-adrenal (HPA) axis is a primary mechanism in the allostatic process through which early life stress (ELS) contributes to disease. Studies of the influence of ELS on children's HPA axis functioning have yielded inconsistent findings. To address this issue, the present study considers multiple types of ELS (maternal depression, paternal depression, and family expressed anger), mental health symptoms, and two components of HPA functioning (traitlike and epoch-specific activity) in a long-term prospective community study of 357 children.

Longitudinal stability and developmental properties of salivary cortisol levels and circadian rhythms from childhood to adolescence.

This study aimed to (1) identify a stable, trait-like component to cortisol and its circadian rhythm, and (2) investigate individual differences in developmental trajectories of HPA-axis maturation. Multiple salivary cortisol samples were collected longitudinally across four assessments from age 9 (3rd grade) through age 15 (9th grade) in a community sample of children (N = 357). Sophisticated statistical models examined cortisol levels and its rhythm over time; effects of age, puberty and gender were primarily considered.

Structure and measurement of depression in youths: applying item response theory to clinical data.

Our goals in this article were to use item response theory (IRT) to assess the relation of depressive symptoms to the underlying dimension of depression and to demonstrate how IRT-based measurement strategies can yield more reliable data about depression severity than conventional symptom counts. Participants were 3,403 children and adolescents from 12 contributing clinical and nonclinical samples; all participants had received the Kiddie Schedule of Affective Disorders and Schizophrenia for School-Aged Children. Results revealed that some symptoms reflected higher levels of depression and were more discriminating than others.

Specificity in the association of anxiety, depression, and atopic disorders in a community sample of adolescents.

The specificity of relationships between anxiety and depressive symptoms, with each of the major atopic disorders of asthma, allergic rhinitis (AR), and atopic dermatitis (AD) was systematically investigated within a single study sample. Participants included 367 adolescents who participated in a community, longitudinal study investigating risk factors for the development of psychiatric and physical health problems. Mental health symptoms were assessed at 7, 9, 11, and 13 years of age.

Early risk factors and developmental pathways to chronic high inhibition and social anxiety disorder in adolescence.

Objective: Evidence suggests that chronic high levels of behavioral inhibition are a precursor of social anxiety disorder. The authors sought to identify early risk factors for, and developmental pathways to, chronic high inhibition among school-age children and the association of chronic high inhibition with social anxiety disorder by adolescence.

Method: A community sample of 238 children was followed from birth to grade 9.

Screening for childhood mental health problems: outcomes and early identification.

Background: Many childhood psychiatric problems are transient. Consequently, screening procedures to accurately identify children with problems unlikely to remit and thus, in need of intervention, are of major public health concern. This study aimed to develop a universal school-based screening procedure based on the answers to three questions: (1) What are the broad patterns of mental health problems from kindergarten to grade 5? (2) What are the grade 5 outcomes of these patterns? (3) How early in school can children likely to develop the most impairing patterns be identified accurately?

Methods: Mothers and teachers reported on a community sample (N = 328) of children's internalizing and externalizing symptoms in kindergarten and grades 1, 3, and 5.

Association of internalizing disorders and allergies in a child and adolescent psychiatry clinical sample.

Objective: To investigate the specificity of the association between internalizing disorders (anxiety and depression) and atopic disorders (asthma, allergic rhinitis, urticaria, and atopic dermatitis) in a child and adolescent psychiatric clinical sample.

Method: A sample of 184 youths was evaluated for current DSM-IV psychiatric disorders (clinical interview) and lifetime history of atopic disorders (parent report and chart review) in a child and adolescent psychiatry clinic from September 1, 2001, through December 31, 2002. Logistic regression analyses were used to assess the differential likelihood of having a lifetime history of atopic disorders among psychiatrically ill youths with and without internalizing disorders.

Salivary dehydroepiandrosterone responsiveness to social challenge in adolescents with internalizing problems.

Background: Dehydroepiandrosterone (DHEA) is an adrenal androgen which is stress responsive and a trigger for pubertal maturation. Studies on basal DHEA suggest protective benefits against anxiety and depression, yet it is unknown whether DHEA responsivity is protective.

Methods: Structural equation modeling examined salivary DHEA responses to a public speaking task (PST) and parent-child conflict discussion paradigm (CDP) in adolescents.

Psychiatric comorbidity associated with atopic disorders in children and adolescents.

This article examines evidence of an association between psychiatric disorders and atopic disorders in children and adolescents. Findings are discussed within a developmental framework and compared with adult studies, when available, to illustrate similarities and differences between youth and adults. Finally, the article discusses the clinical relevance of comorbid psychiatric and atopic disorders.

Antibiotic prophylaxis with azithromycin or penicillin for childhood-onset neuropsychiatric disorders.

Background: The acronym PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections) describes a subgroup of children with obsessive-compulsive disorder and/or tic disorder that experience symptom exacerbations following streptococcal infections. We hypothesized that the prevention of streptococcal infections among children in the PANDAS subgroup would decrease neuropsychiatric symptom exacerbations.

Methods: Twenty-three subjects with PANDAS were enrolled in a double blind, randomized controlled trial.

Prevalence of obsessive-compulsive disorder in patients with systemic lupus erythematosus.

Background: The goal of this pilot study was to investigate the prevalence of obsessive-compulsive disorder (OCD) in a group of patients with systemic lupus erythematosus (SLE).

Method: Fifty adult patients enrolled in out-patient SLE studies at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (February 1995-October 1996) completed a self-report questionnaire adapted from the Yale-Brown Obsessive Compulsive Scale and an in-person psychiatric clinical interview with a psychiatrist or psychiatric clinical nurse specialist. DSM-IV lifetime diagnosis of OCD was determined by clinical interview.

Relationship between separation anxiety disorder, parental panic disorder, and atopic disorders in children: a controlled high-risk study.

Objective: To test the hypotheses that rates of atopic disorders are elevated in offspring of parents with panic disorder (PD) and in children with separation anxiety disorder (SAD).

Method: Rates of atopic disorders were assessed in 343 offspring (aged 6-17 years) of parents with PD, nonpanic psychiatric disorders, and no psychiatric disorder. Lifetime history of atopic disorders was determined by parental responses to a clinician-administered questionnaire assessing medical treatment for asthma and allergies.
