Body mass indexes and lipid profiles in hospitalized children and adolescents exposed to atypical antipsychotics

Gut microbiome profiles may be related to atypical antipsychotic associated overweight in Asian children with psychiatric disorder: a preliminary study

Objective

Atypical antipsychotics (APs) modify the gut microbiome, and weight gain in response to AP could be mediated by the gut microbiome. Thus, the present study aimed to explore the changes in the gut bacterial microbiome in AP-exposed children with obesity.

Methods

To rule out the confounder of AP indication, the gut bacterial microbiome was compared between healthy controls (Con) and AP-exposed individuals with overweight (APO) or normal weight (APN). Fifty-seven AP-treated outpatients (21 APO and 36 APN) and 25 Con were included in this cross-sectional microbiota study.

Results

AP users, regardless of body mass index, exhibited decreased microbial richness and diversity and a distinct metagenomic composition compared to the Con. Although no differences in the microbiota structure were observed between APO and APN groups, the APO group was characterised by a higher abundance of Megamonas and Lachnospira. Additionally, the differences in the microbial functions were observed between APO and APN groups.

Conclusions

The gut bacterial microbiota of APO children revealed taxonomic and functional differences compared to Con and APN. Further studies are needed to verify these findings and to explore the temporal and causal relationships between these variables.

The clinical and behavioral cardiometabolic risk of children and young people on mental health inpatient units: A systematic review and meta-analysis

OBJECTIVE

Serious mental illness is associated with physical health comorbidities, however most research has focused on adults. We aimed to synthesise existing literature on clinical and behavioral cardiometabolic risk factors of young people on mental health inpatient units.

METHODS

A systematic review and meta-analysis was conducted, using electronic searches of PsycINFO, EMBASE, AMED, Cochrane Central Register of Controlled Trials, and Ovid MEDLINE. Eligible studies included child/adolescent mental health inpatient units for <25 years, reporting clinical/behavioral cardiometabolic risk factors. Studies containing adult samples, case-studies, or eating disorder populations were excluded. The main clinical outcome was weight, and main behavioral outcome was tobacco use.

RESULTS

Thirty-nine studies were identified (n = 809,185). Pooled prevalence rates of young people who were overweight (BMI > 25) was 32.4% (95% CI 26.1%-39.5%; n = 2789), and who were obese (BMI > 30) was 15.5% (95% CI 4.5%-41.6%; n = 2612). Pooled prevalence rates for tobacco use was 51.5% (95% CI 32.2-70.2; N = 804,018). Early signs of metabolic risk were observed; elevated blood cholesterol, presence of physical health conditions, and behavioral risk factors (e.g. physical inactivity).

CONCLUSIONS

This review highlights the vulnerability of young people admitted to inpatient units and emphasises the opportunity to efficiently monitor, treat and intervene to target physical and mental health.

Genetic pleiotropy between mood disorders, metabolic, and endocrine traits in a multigenerational pedigree

Bipolar disorder (BD) is a mental disorder characterized by alternating periods of depression and mania. Individuals with BD have higher levels of early mortality than the general population, and a substantial proportion of this is due to increased risk for comorbid diseases. To identify the molecular events that underlie BD and related medical comorbidities, we generated imputed whole-genome sequence data using a population-specific reference panel for an extended multigenerational Old Order Amish pedigree (n = 394), segregating BD and related disorders. First, we investigated all putative disease-causing variants at known Mendelian disease loci present in this pedigree. Second, we performed genomic profiling using polygenic risk scores (PRS) to establish each individual's risk for several complex diseases. We identified a set of Mendelian variants that co-occur in individuals with BD more frequently than their unaffected family members, including the R3527Q mutation in APOB associated with hypercholesterolemia. Using PRS, we demonstrated that BD individuals from this pedigree were enriched for the same common risk alleles for BD as the general population (β = 0.416, p = 6 × 10^-4). Furthermore, we find evidence for a common genetic etiology between BD risk and polygenic risk for clinical autoimmune thyroid disease (p = 1 × 10^-4), diabetes (p = 1 × 10^-3), and lipid traits such as triglyceride levels (p = 3 × 10^-4) in the pedigree. We identify genomic regions that contribute to the differences between BD individuals and unaffected family members by calculating local genetic risk for independent LD blocks. Our findings provide evidence for the extensive genetic pleiotropy that can drive epidemiological findings of comorbidities between diseases and other complex traits.

Improved Metabolic and Psychiatric Outcomes with Discontinuation of Atypical Antipsychotics in Youth Hospitalized in a State Psychiatric Facility

OBJECTIVES

To assess the impact of antipsychotic tapering and discontinuation on measures of metabolic functioning and psychiatric symptom severity in severely impaired youth hospitalized in a psychiatric state hospital.

METHODS

The study examined psychiatric and metabolic measures in 67 hospitalized children and adolescents (mean age 11.9; 56 with discontinued use of antipsychotics, 10 with continued use of antipsychotics, and 1 started on an antipsychotic) from admission to discharge.

RESULTS

Upon admission, 56 youth were tapered off of antipsychotic medications, started on other forms of pharmacotherapy (92.9% were started on medications used to treat attention-deficit/hyperactivity disorder), and received evidence-based behavioral programming and were ultimately discharged from the hospital. The mean duration of treatment was 228 days for the discontinuation group and 204 days for the continuation group. Significant decreases in body mass index [BMI; t(53) = 7.12, p = 0.0001] and BMI percentile [t(53) = 6.73, p = 0.0001] were found from admission to discharge in the antipsychotic discontinuation group. Changes in BMI, BMI percentile, or systolic blood pressure were not found in the group (n = 10) who were maintained on antipsychotics. Both groups experienced a significant increase in their Global Assessment of Functioning score [t(52) = 19.98, p = 0.0001 for discontinued; t(8) = 5.092, p = 0.001 for maintained]. Psychiatric symptom severity scores significantly improved in many subscales relevant to disruptive behaviors and mood disorders for those who were removed from the medications. For those maintained on the antipsychotics, there were fewer changes in psychiatric symptom scores.

CONCLUSION

Discontinuation of atypical antipsychotic medications in conjunction with tailoring treatment to presenting diagnoses resulted in metabolic and psychiatric symptom improvement among severely impaired state hospital inpatient youth. These results serve as a feasibility demonstration that discontinuation of antipsychotics does not provoke psychiatric destabilization, particularly among disruptive behavior disordered youth.

Effect of Psychopharmacotherapy on Body Mass Index Among Children and Adolescents with Bipolar Disorders

OBJECTIVE

To assess the long-term effect of all treatment options for pediatric bipolar disorders on body mass index (BMI) and to explore individual characteristics associated with less BMI increase during psychotropic medication exposures.

METHODS

A retrospective cohort study was conducted by using the 1995 to 2010 General Electric Electronic Medical Record database. Individuals aged 18 years or younger who had a new bipolar disorder episode were identified. Treatment exposure was defined based on the medication regimens patients received, which include atypical antipsychotic (AT) monotherapy, mood stabilizer (MS) monotherapy, antidepressant (AD) monotherapy, AT+MS polytherapy, AT+AD polytherapy, MS+AD polytherapy, and no treatment. Both treatment exposure and BMI were coded as time varying, which could change from month to month. According to the duration of treatment and the availability of BMI measures, individuals were followed for up to 3, 6, 9, and 12 months since the treatment initiation. Repeated-measures mixed models were applied to compare the impact of different medication regimens and the length of drug exposure on BMI after adjusting for the baseline BMI, sociodemographic factors, comorbidities, and psychotherapy.

RESULTS

A total of 2299 treated and 4544 untreated children and adolescents who met the inclusion criteria were identified. Analysis using repeated-measures mixed models showed that those on AT monotherapy (the reference group) had a gradually diminished, but statistically significant, monthly increase in BMI during all durations of drug exposure (3 months: 0.36 kg/m², 6 months: 0.20 kg/m², 9 months: 0.17 kg/m², and 12 months: 0.16 kg/m²). As compared with AT monotherapy, the magnitude of increase in BMI associated with MS, AD monotherapy, and no treatment was significantly less at all time points, indicating less steep slopes of BMI change over time compared with AT monotherapy, especially during the short-term exposure. The combinations of AT with other psychotropic medications (ATMS, ATAD) were associated with a similar BMI increase as AT monotherapy. Individual characteristics found to be associated with a less increase in BMI during psychotropic medication exposure were being younger and having a higher baseline BMI.

CONCLUSION

The long-term use of atypical antipsychotics, both as monotherapy or in combination with other psychotropic medications in children and adolescents with bipolar disorder, was associated with a steady and cumulative increase in BMI.

Bipolar Spectrum Disorders in Male Youth: The Interplay between Symptom Severity, Inflammation, Steroid Secretion, and Body Composition

The morbidity and societal burden of youth bipolar spectrum disorders (BSD) are high. These disorders are multisystemic in that adult populations there are clear interactions with inflammatory processes and steroidal physiological systems. There are much less data concerning these areas of study in youth populations with BSD. This is surprising given the association of youth-onset BSD with puberty and its associated physiological changes. In this mini-review, we overview the theoretical role of inflammatory processes and steroidal physiological systems in youth BSD, describe the greater literature in adult populations, detail the literature in youth populations when available, and overview current proposed molecular mechanistic pathways and interaction effects based on the available data. We also attend to the interplay of this complex system with body composition and weight gain, an especially important consideration in relation to the role of second generation antipsychotics as the first line treatment for youth with BSD in major clinical guidelines. A developmental model of early onset BSD for boys is hypothesized with pubertal hormonal changes increasing risk for first (hypo-)manic/depressive episode. The dramatic androgen rise during puberty might be relevant for first onset of BSD in boys. A shift from general hypercortisolism driven by glucocorticoid resistance to hypocortisolism with further disease progression is assumed, while increased levels of inflammation are functionally associated with endocrine dysregulation. The interacting role of overweight body habitus and obesity in youth with BSD further indicates leptin resistance to be a central moderator of the dynamic neurobiology of BSD in youth. The intent of this mini-review is to advance our knowledge of youth BSD as multisystemic disorders with important contributions from endocrinology and immunology based on a developmental perspective. This knowledge can influence current clinical care and more importantly inform future research.

Major Depressive Disorder and Bipolar Disorder Predispose Youth to Accelerated Atherosclerosis and Early Cardiovascular Disease: A Scientific Statement From the American Heart Association

In the 2011 "Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents," several medical conditions among youth were identified that predispose to accelerated atherosclerosis and early cardiovascular disease (CVD), and risk stratification and management strategies for youth with these conditions were elaborated. Major depressive disorder (MDD) and bipolar disorder (BD) among youth satisfy the criteria set for, and therefore merit inclusion among, Expert Panel tier II moderate-risk conditions. The combined prevalence of MDD and BD among adolescents in the United States is ≈10%, at least 10 times greater than the prevalence of the existing moderate-risk conditions combined. The high prevalence of MDD and BD underscores the importance of positioning these diseases alongside other pediatric diseases previously identified as moderate risk for CVD. The overall objective of this statement is to increase awareness and recognition of MDD and BD among youth as moderate-risk conditions for early CVD. To achieve this objective, the primary specific aims of this statement are to (1) summarize evidence that MDD and BD are tier II moderate-risk conditions associated with accelerated atherosclerosis and early CVD and (2) position MDD and BD as tier II moderate-risk conditions that require the application of risk stratification and management strategies in accordance with Expert Panel recommendations. In this scientific statement, there is an integration of the various factors that putatively underlie the association of MDD and BD with CVD, including pathophysiological mechanisms, traditional CVD risk factors, behavioral and environmental factors, and psychiatric medications.

"First do no harm." A systematic review of the prevalence and management of antipsychotic adverse effects

AIMS

We aim to identify the prevalence and management strategies of nine clinically important categories of antipsychotic adverse effects, namely: extrapyramidal symptoms; sedation; weight gain; type II diabetes; hyperprolactinaemia; metabolic syndrome, dyslipidaemia; sexual dysfunction; and cardiovascular effects.

BACKGROUND

Antipsychotic drugs are widely prescribed for schizophrenia and other mental disorders. The adverse effects of antipsychotics are common, with a potential negative impact on adherence and engagement. Despite this, the scientific study of the prevalence or management of adverse antipsychotic effects is a neglected area.

METHOD

A systematic review was undertaken using pre-defined search criteria and three databases, with hand searching of citations and references. Inclusion was agreed on by two independent researchers after review of abstracts or full text. Quality analysis of included studies was conducted using pre-agreed criteria.

RESULTS

In total, 53 studies met inclusion criteria, revealing the following: (1) antipsychotic polypharmacy was associated with increased frequency of adverse effects, and (2) a longer duration of treatment is associated with greater severity (e.g. higher BMI); (3) clozapine was more strongly associated with metabolic disturbance than other antipsychotics in three studies and olanzapine was associated with the most weight gain in three studies; (4) hyperprolactinaemia was more common in women than men, but 50% men noted sexual dysfunction versus 25-50% in women; (5) despite clinical guideline recommendations there is a low rate of baseline testing for lipids and glucose; and (6) seven studies described adverse effect management strategies, but only two examined their efficacy - one found a significant reduction in weight with non-pharmacological group therapy and the other found a significant reduction in dyslipidaemia with statins.

CONCLUSIONS

Antipsychotic adverse effects are diverse and frequently experienced, but are not often systematically assessed. There is a need for further scientific study concerning the management of these side effects.

Risk factors for weight gain and metabolic syndrome in adolescents with psychiatric disorders: a historical prospective study

OBJECTIVE

Adolescents with mental disorders are at increased risk for being overweight or obese, and subsequently developing metabolic syndrome. However, data regarding risk factors for weight gain during psychiatric hospitalization of adolescents are limited and inconsistent. The aim of this study was to investigate the sociodemographic, clinical, and pharmacological risk factors for weight gain during psychiatric treatment, in order to improve prevention of subsequent metabolic syndrome.

METHODS

We conducted a historical prospective study of 146 adolescent patients (mean age 15.2±1.9 years, 52.7% males), consecutively admitted for day treatment in an adolescent day unit (length of stay 141±76 days). Anthropometric measurements and laboratory analyses of fasting glucose and lipid levels were conducted as part of the routine medical care at admission and discharge. Psychiatric diagnoses, medication histories, and sociodemographic data were obtained from the electronic medical records system.

RESULTS

A significant increase in age- and gender adjusted body mass index (BMI) (i.e., z score) was observed (0.5±1.2 vs. 0.7±1.1 at admission and discharge, respectively, p<0.001). Male subjects were more prone to weight gain than females (odds ratio [OR]=3.5, 95% CI=1.2-10.3) and BMI z score at admission was inversely associated with weight gain (R (2)=0.2, p<0.0001). Surprisingly, age at admission, psychiatric diagnoses, length of stay, and number of medications were not associated with weight gain. Despite weight gain, fasting blood glucose and lipid profile did not change significantly during the study period.

CONCLUSIONS

Hospitalization of adolescents in a psychiatric day unit may be associated with a significant weight gain, especially in male subjects and those with normal weight at admission. Efforts should be aimed to reduce weight gain among youth with psychiatric disorders during treatment, to avoid a subsequent metabolic syndrome.

Antipsychotic polypharmacy in children and adolescents at discharge from psychiatric hospitalization

STUDY OBJECTIVE

Antipsychotic polypharmacy-the use of more than one antipsychotic concomitantly-has increased in children and adolescents and may be associated with increased adverse effects, nonadherence, and greater costs. Thus, we sought to examine the demographic and clinical characteristics of psychiatrically hospitalized children and adolescents who were prescribed antipsychotic polypharmacy and to identify predictors of this prescribing pattern.

DESIGN

Retrospective medical record review.

SETTING

The inpatient psychiatric unit of a large, acute care, urban children's hospital.

PATIENTS

One thousand four hundred twenty-seven children and adolescents who were consecutively admitted and discharged between September 2010 and May 2011.

MEASUREMENTS AND MAIN RESULTS

At discharge, 840 (58.9%) of the 1427 patients were prescribed one or more antipsychotics, and 99.3% of these received second-generation antipsychotics. Of these 840 patients, 724 (86.2%) were treated with antipsychotic monotherapy, and 116 (13.8%) were treated with antipsychotic polypharmacy. Positive correlations with antipsychotic polypharmacy were observed for placement or custody outside the biological family; a greater number of previous psychiatric admissions; longer hospitalizations; admission for violence/aggression or psychosis; and intellectual disability, psychotic, disruptive behavior, or developmental disorder diagnoses. Negative correlations with antipsychotic polypharmacy included admission for suicidal ideation/attempt or depression, and mood disorder diagnoses. Significant predictors of antipsychotic polypharmacy included admission for violence or aggression (odds ratio [OR] 2.76 [95% confidence interval (CI) 1.36-5.61]), greater number of previous admissions (OR 1.21 [95% CI 1.10-1.33]), and longer hospitalizations (OR 1.08 [95% CI 1.04-1.12]). In addition, diagnoses of intellectual disability (OR 2.62 [95% CI 1.52-4.52]), psychotic disorders (OR 5.60 [95% CI 2.29-13.68]), and developmental disorders (OR 3.18 [95% CI 1.78-5.65]) were predictors of antipsychotic polypharmacy.

CONCLUSION

Certain youth may have a higher likelihood of being prescribed antipsychotic polypharmacy, which should prompt careful consideration of medication treatment options during inpatient hospitalization. Future examinations of the rationale for combining antipsychotics, along with the long-term safety, tolerability, and cost effectiveness of these therapies, in youth are urgently needed.

Prevalence and correlates of antipsychotic polypharmacy in children and adolescents receiving antipsychotic treatment

Antipsychotic polypharmacy (APP), which is common in adults with psychotic disorders, is of unproven efficacy and raises safety concerns. Although youth are increasingly prescribed antipsychotics, little is known about APP in this population. We performed a systematic PubMed search (last update 26 January 2013) of studies reporting the prevalence of APP in antipsychotic-treated youth. Summary statistics and statistical tests were calculated at the study level and not weighted by sample size. Fifteen studies (n = 58 041, range 68-23 183) reported on APP in youth [mean age = 13.4 ± 1.7 yr, 67.1 ± 10.2% male, 77.9 ± 27.4% treated with second-generation antipsychotics (SGAs)]. Data collected in these studies covered 1993-2008. The most common diagnoses were attention-deficit hyperactivity disorder (ADHD; 39.9 ± 23.5%) and conduct disorder/oppositional defiant disorder (CD/ODD; 33.6 ± 24.8). In studies including predominantly children (mean age = <13 yr, N = 5), the most common diagnosis were ADHD (50.6 ± 25.4%) and CD/ODD (39.5 ± 27.5%); while in studies with predominantly adolescents (mean age = ⩾13 yr, N = 7) the most common diagnoses were schizophrenia-spectrum disorders (28.6 ± 23.8%), anxiety disorders (26.9 ± 14.9%) and bipolar-spectrum disorders (26.6 ± 7.0%), followed closely by CD/ODD (25.8 ± 17.7). The prevalence of APP among antipsychotic-treated youth was 9.6 ± 7.2% (5.9 ± 4.5% in child studies, 12.0 ± 7.9% in adolescent studies, p = 0.15). Higher prevalence of APP was correlated with a bipolar disorder or schizophrenia diagnosis (p = 0.019) and APP involving SGA+SGA combinations (p = 0.0027). No correlation was found with APP definition [⩾1 d (N = 10) vs. >30-⩾90 d (N = 5), p = 0.88]. Despite lacking safety and efficacy data, APP in youth is not uncommon, even in samples predominantly consisting of non-psychotic patients. The duration, clinical motivations and effectiveness of this practice require further study.

Metabolic effects of antipsychotics in prepubertal children: a retrospective chart review

OBJECTIVE

Antipsychotics, especially atypical ones, are in common use in children and adolescents with psychotic or affective spectrum disorders, as well as in various other psychopathologies. The adverse effects of atypical antipsychotics in children and adolescents are similar to those seen in adults, and include weight gain, elevated blood glucose levels, and hyperlipidemia. In this retrospective chart review, we compared these adverse events in children who were treated with typical, atypical, or no antipsychotic treatment.

METHODS

The medical charts of 72 children, 65 boys and 7 girls, were reviewed. All children were 6-13 years old (mean age 9.5±1.7 years). In total, 48 children received antipsychotic treatment, and 24 children were in the control group. Data were extracted from the medical charts, including weight, height, body mass index (BMI), blood pressure, aspartate transaminase (AST), alanine transaminase (ALT), triglycerides, total cholesterol, and glucose blood levels. We examined the values in the beginning of the antipsychotic treatment and at release from the hospital in the study group, and at admission and in the end of the drug-free period or at release from the hospital (a duration of at least 4 weeks) in the control group.

RESULTS

The average weight gain was 3.9±3.8 kg in the atypical antipsychotic treatment (AAT) group, 1.1±4.4 kg in the typical antipsychotic treatment (TAT) group, and 0.23±2.9 kg in the control group. The average increase in BMI was 15.1±22.0 percentiles in the AAT group, 6.4±14.2 percentiles in the TAT group, and 1.6±12.5 percentiles in the control group. No statistically significant difference was found in the increase in height percentile. There were no significant differences in the rates of elevated values of serum triglycerides, cholesterol, AST, ALT, or fasting blood glucose.

CONCLUSIONS

We found a significant increase in both absolute weight gain and BMI percentile following atypical antipsychotic treatment. In contrast, typical antipsychotic treatment did not affect weight gain significantly, and the same was true for the control group. In addition, the rates of elevated values of biochemical parameters (AST, ALT, total cholesterol, triglycerides, and fasting blood glucose levels) were very low at the beginning of the study, and were not significantly altered by the various treatments.

The comparison of glucose and lipid metabolism parameters in drug-naïve, antipsychotic-treated, and antipsychotic discontinuation patients with schizophrenia

BACKGROUND

Although many studies have reported that glucose and lipid metabolism disorders are a significant side effect associated with the use of antipsychotic drugs, the characteristics of glucose and lipid metabolism disorders in patients with schizophrenia who are taking antipsychotic drugs remain poorly understood, and the possible effects that antipsychotic discontinuation may have on glucose and lipid metabolism remain unclear.

METHODS

The sample consisted of 131 Chinese patients with schizophrenia, including 70 first-episode, drug-naïve patients; 33 patients who had received continuous antipsychotic drug treatment for ≥1 year prior to the beginning of the study; and 28 patients who had discontinued antipsychotic drug treatment for ≥3 months prior to the beginning of study. We compared the glucose and lipid metabolic parameter levels among the three groups of patients with schizophrenia. All assessments were performed upon hospital admission.

RESULTS

The characteristics of glucose and lipid metabolism disorders in Chinese patients with schizophrenia who are taking antipsychotic drugs included significant augmentation of the body mass index and waist circumference, significantly higher levels of fasting plasma insulin and insulin resistance, and significantly lower plasma high-density lipoprotein cholesterol levels. Antipsychotic discontinuation appeared to not significantly improve any plasma glucose and lipid metabolic parameter levels.

CONCLUSION

The results suggest that antipsychotic drugs aggravate glucose and lipid metabolism disorders and that antipsychotic discontinuation is generally not associated with improvements in the parameters that indicate glucose and lipid metabolism disorders in Chinese patients with schizophrenia.

Weight gain and increase of body mass index among children and adolescents treated with antipsychotics: a critical review

We performed an updated review of the available literature on weight gain and increase of body mass index (BMI) among children and adolescents treated with antipsychotic medications. A PubMed search was conducted specifying the following MeSH terms: (antipsychotic agents) hedged with (weight gain) or (body mass index). We selected 127 reports, including 71 intervention trials, 42 observational studies and 14 literature reviews. Second-generation antipsychotics (SGAs), in comparison with first-generation antipsychotics, are associated with a greater risk for antipsychotic-induced weight gain although this oversimplification should be clarified by distinguishing across different antipsychotic drugs. Among SGAs, olanzapine appears to cause the most significant weight gain, while ziprasidone seems to cause the least. Antipsychotic-induced BMI increase appears to remain regardless of the specific psychotropic co-treatment. Children and adolescents seem to be at a greater risk than adults for antipsychotic-induced weight gain; and the younger the child, the higher the risk. Genetic or environmental factors related to antipsychotic-induced weight gain among children and adolescents are mostly unknown, although certain genetic factors related to serotonin receptors or hormones such as leptin, adiponectin or melanocortin may be involved. Strategies to reduce this antipsychotic side effect include switching to another antipsychotic drug, lowering the dosage or initiating treatment with metformin or topiramate, as well as non-pharmacological interventions. Future research should avoid some methodological limitations such as not accounting for age- and sex-adjusted BMI (zBMI), small sample size, short period of treatment, great heterogeneity of diagnoses and confounding by indication.

Mental health and food consumption among California children 5-11 years of age

OBJECTIVE

The purpose of this research was to determine if poor mental health is associated with the intake of specific foods among California children.

DESIGN

Secondary data analysis of the 2007 and 2009 California Health Interview Survey (CHIS) was conducted. Mental health was measured using a shortened version of the Strengths and Difficulties Questionnaire (SDQ). Dietary measures were self-reported servings of fruit, vegetables, 100% fruit juice, high sugar foods, soda/sweetened drinks, and French fries/fried potatoes consumed the previous day, as well as frequency of fast food consumed during the past week.

SETTING

Phone interviews were conducted via the CHIS on households in California.

SUBJECTS

Data belonging to children (n = 11,190) ages 5-11 years whose parents completed the CHIS 2007 and 2009 random-dial telephone surveys was investigated.

RESULTS

Of an estimated annual population of 3.7 million children, 180,000 (4.9%) had poor mental health. Children with poor mental health consumed more soda/sweetened drinks (0.60 vs 0.45 servings per day, p = 0.024), French fries/fried potatoes (0.27 vs 0.14 servings per day, p = 0.003), and fast food (2.02 vs 1.38 servings per week, p = 0.009) compared to children with good mental health. Mental health was not associated with other dietary measures. Adjusting for relevant socio-demographic characteristics, logistic regression found poor mental health to be significantly associated with any consumption of French fries/fried potatoes (odds ratio (OR) = 2.0, p = 0.001) or vegetables (OR 0.6, p = 0.005) on the previous day, and fast food two or more times in the past week (OR 1.7, p < 0.001). Interaction analysis revealed that an estimated 33% of girls with poor mental health consumed French fries, compared to 12% of girls with good mental health (OR 2.91, p = 0.006).

CONCLUSIONS

Children with poor mental health are more likely to consume calorie-dense but nutrient-poor foods compared to their counterparts. Intake of such foods may contribute to worse physical health as these children mature.

Antipsychotic and psychostimulant drug combination therapy in attention deficit/hyperactivity and disruptive behavior disorders: a systematic review of efficacy and tolerability

This systematic review examines treatment guidelines, efficacy/effectiveness, and tolerability regarding the use of antipsychotics concurrently with psychostimulants in treating aggression and hyperactivity in children and adolescents. Articles examining the concurrent use of antipsychotics and psychostimulants to treat comorbid attention deficit/hyperactivity disorder (ADHD) and disruptive behavior disorders (DBDs) were identified and their results were summarized and critically analyzed. Antipsychotic and stimulant combination therapy is recommended by some guidelines, but only as a third-line treatment following stimulant monotherapy and stimulants combined with behavioral interventions to treat aggression in patients with ADHD. Some studies suggest efficacy/effectiveness for an antipsychotic and stimulant combination in the treatment of aggression and hyperactivity in children and adolescents. However, the data do not clearly demonstrate superiority compared to antipsychotic or psychostimulant monotherapy. Most studies were performed over short time periods, several lacked blinding, few studies used any placebo control, and no comparisons were made with behavioral interventions. There are concerns about the tolerability of combination therapy, but data do not suggest significantly worse adverse effects for combination compared to either antipsychotic or stimulant monotherapy. Conversely, and contrary to speculation, use of a stimulant does not significantly reduce metabolic effects of antipsychotics. Combination treatment with antipsychotics and psychostimulants is used frequently, and increasingly more often. Few studies have directly examined this combination for the treatment of ADHD and DBDs. Further studies are necessary to confirm the efficacy and tolerability of the concurrent use of antipsychotics and psychostimulants in children and adolescents.

Collaborative role of the pediatrician in the diagnosis and management of bipolar disorder in adolescents

Despite the complexity of diagnosis and management, pediatricians have an important collaborative role in referring and partnering in the management of adolescents with bipolar disorder. This report presents the classification of bipolar disorder as well as interviewing and diagnostic guidelines. Treatment options are described, particularly focusing on medication management and rationale for the common practice of multiple, simultaneous medications. Medication adverse effects may be problematic and better managed with collaboration between mental health professionals and pediatricians. Case examples illustrate a number of common diagnostic and management issues.

Medication use and spending trends among children with ADHD in Florida's Medicaid program, 1996-2005

OBJECTIVE

How the introduction of new pharmaceuticals affects spending for treatment of children with attention-deficit hyperactivity disorder (ADHD) is unknown. This study examined trends in use of pharmaceuticals and their costs among children with ADHD from 1996 to 2005.

METHODS

This observational study used annual cohorts of children ages three to 17 with ADHD (N=107,486 unique individuals during the study period) from Florida Medicaid claims to examine ten-year trends in the predicted probability for medication use for children with ADHD with and without psychiatric comorbidities as well as mental health spending and its components. Additional outcome measures included average price per day and average number of days filled for medication classes.

RESULTS

Overall, the percentage of children with ADHD treated with ADHD drugs increased from 60% to 63%, and the percentage taking antipsychotics more than doubled, from 8% to 18%. In contrast, rates of antidepressant use declined from 21% to 15%, and alpha agonist use was constant, at 15%. Mental health spending increased 61%, with pharmaceutical spending representing the fastest-rising component (up 192%). Stimulant spending increased 157%, mostly because of increases in price per prescription. Antipsychotic spending increased 588% because of increases in both price and quantity (number of days used). By 2005, long-acting ADHD drugs accounted for over 90% of stimulant spending.

CONCLUSIONS

Long-acting ADHD drugs have rapidly replaced short-acting stimulant use among children with ADHD. The use of antipsychotics as a second-tier agent in treating ADHD has overtaken traditional agents such as antidepressants or alpha agonists, suggesting a need for research into the efficacy and side effects of second-generation antipsychotics among children with ADHD.

Pharmacotherapy of bipolar disorder in children and adolescents: recent progress

Child and adolescent bipolar disorder (BPD) is a serious psychiatric disorder that often causes significant impairment in functioning. Pharmacological intervention is the cornerstone of treatment for bipolar youth, although psychotherapeutic interventions may be beneficial as adjunctive treatment. Medications used for the treatment of BPD in adults are still commonly used for bipolar children and adolescents. With the recent US FDA indication of risperidone, aripiprazole, quetiapine and olanzapine for the treatment of bipolar youth, the atypical antipsychotics are rapidly becoming a first-line treatment option. However, these agents are associated with adverse effects such as increased appetite, weight gain and type II diabetes mellitus. Although several evidence-based medications are now available for the treatment of BPD in younger populations, additional studies to evaluate the short- and long-term efficacy and potential for adverse events of these and other medications are needed.

Multiple psychiatric diagnoses common in privately insured children on atypical antipsychotics

OBJECTIVE

To evaluate the prevalence of atypical antipsychotic use in privately insured children and the diagnoses associated with treatment.

STUDY DESIGN

Claims were used to conduct a retrospective cohort study of children aged 2 through 18 years in the Midwest, covered by private insurance between 2002 and 2005 (n = 172,766). The 1-year prevalence of children receiving atypical antipsychotics was determined along with associated diagnoses.

RESULTS

The 1-year prevalence of atypical antipsychotics ranged from 7.9 per 1000 in 2002 to 9.0 in 2005. The leading diagnoses were disruptive behavior disorders (67%), mood disorders (65%), and anxiety disorders (43%).The authors found that 75% of children on atypical antipsychotics had more than one psychiatric diagnosis.

CONCLUSIONS

Atypical antipsychotic use is primarily seen in children who have multiple psychiatric diagnoses. Studies are needed to assess the long-term safety and effectiveness in such patients with multiple diagnoses.

Antipsychotic and mood stabilizer efficacy and tolerability in pediatric and adult patients with bipolar I mania: a comparative analysis of acute, randomized, placebo-controlled trials

OBJECTIVE

To compare antipsychotic and mood stabilizer (MS) efficacy and tolerability in youth and adults with bipolar mania.

METHODS

Medline/PubMed search for studies including: (i) youth (< 18 years) or adults (> or = 18 years); (ii) bipolar I disorder; (iii) double-blind, randomized, placebo-controlled trial (DB-RPCT); (iv) < or = 12 weeks of treatment; and (v) calculable effect sizes (ES) and/or numbers needed to treat/harm (NNT/NNH) +/- 95% confidence intervals (CI). Non-overlapping 95% CIs determined significant group differences.

RESULTS

We identified nine DB-RPCTs in youth (n = 1,609), 5 evaluating second-generation antipsychotics (SGAs) (n = 1,140) and 4 evaluating MSs (n = 469). We also identified 23 DB-RPCTs in adults (n = 6,501), 14 including SGAs (n = 3,297), 5 using haloperidol as an active comparator (n = 580), and 11 including MSs (n = 2,581). Young Mania Rating Scale scores improved significantly more with SGAs than MSs in youth (ES = 0.65, CI: 0.53-0.78 versus 0.24, CI: 0.06-0.41) and adults (ES = 0.48, CI: 0.41-0.55 versus 0.24, CI: 0.17-0.31). After excluding topiramate studies, SGAs had larger ES than MSs only in youth (ES = 0.65, CI: 0.53-0.78 versus 0.20, CI: 0.02-0.39), but not adults (ES = 0.48, CI: 0.41-0.55 versus 0.46, CI: 0.37-0.55). However, in adults SGAs had significantly larger ES regarding Clinical Global Impressions scores than MSs, even without topiramate (ES = 0.75, CI: 0.68-0.82 versus 0.24, CI: 0.07-0.41). Rates of response, remission, and discontinuation due to any reason compared to placebo were similar between medication and age groups, except for more favorable NNTs for remission with SGAs than MSs in adults after excluding topiramate. SGAs caused more weight gain than MSs in youth (ES = 0.53, CI: 0.41-0.66 versus 0.10, CI: -0.12-0.33), but not in adults (ES = 0.13, CI: 0.05-0.22 versus 0.00, CI: -0.08-0.08). However, results were heterogeneous and not significant in either age group after excluding topiramate. Nevertheless, SGA-related weight gain was significantly greater in youth than adults. In youth, SGA-related somnolence was greater than with MSs (NNH = 4.7, CI: 3.9-6.0 versus 9.5, CI: 6.3-23.5), and more likely than in adults (NNH = 7.1, CI: 6.1-8.8). Conversely, youth experienced less akathisia with SGAs than adults (NNH = 20.4, CI: 14.1-36.5 versus 10.2, CI: 8.1-13.7), likely due to lower doses/slower titration.

CONCLUSIONS

In treating mania, potentially greater short-term efficacy compared to placebo with SGAs versus MS needs to be balanced against increased adverse events, especially in youth.

Weight gain and metabolic abnormalities during extended risperidone treatment in children and adolescents

OBJECTIVE

The aim of this study was to investigate the prevalence of clinical and laboratory metabolic abnormalities during long-term risperidone treatment in children and adolescents.

METHODS

Medically healthy 7- to 17-year-old children chronically treated, in a naturalistic setting, with risperidone were recruited through child psychiatry clinics. Anthropometric measurements and laboratory testing were conducted. Developmental and medication histories were obtained from medical records.

RESULTS

In 99 patients treated with risperidone for an average of 2.9 years, a significant increase in age- and gender-adjusted weight and body mass index (BMI) (i.e., z-scores) was observed. Concomitant treatment with psychostimulants did not attenuate this weight gain. Risperidone-associated weight gain was negatively correlated with the BMI z-score obtained at the onset of risperidone treatment. Compared to lean children, overweight and obese children had higher odds of metabolic abnormalities, including increased waist circumference, hypertriglyceridemia, and low high-density lipoprotein cholesterol (HDL-C). They also tended to have a higher insulin level and homeostasis model assessment insulin resistance (HOMA-IR) index. As a result, upon recruitment in the study, children with excessive weight were 12 times more likely to have at least one laboratory metabolic abnormality and seven times more likely to have at least one criterion of the metabolic syndrome compared to lean subjects. In contrast to excessive weight status, gaining > or =0.5 BMI z-score point during risperidone treatment was not associated with a significantly higher occurrence of metabolic disturbances.

CONCLUSIONS

The long-term use of risperidone, especially when weight is above normal, is associated with a number of metabolic abnormalities but a low prevalence of the metabolic syndrome phenotype. Future studies should evaluate the stability of these abnormalities over time.

Obesity identified by discharge ICD-9 codes underestimates the true prevalence of obesity in hospitalized children

OBJECTIVES

To define inpatient care of obese children with or without an obesity diagnosis.

STUDY DESIGN

A total of 29,352 inpatient discharges (18,459 unique inpatients) from a tertiary children's hospital were analyzed. Body mass index (BMI) was calculated from measured height and weight. "Obesity" was defined as BMI >or=95th percentile by using Centers for Disease Control and Prevention 2000 growth charts. "Diagnosed obesity" was defined by primary, secondary or tertiary International Classification of Diseases, Ninth Revision codes for "obesity" or "overweight." Analyses controlled for multiple inpatient records per individual.

RESULTS

A total of 5989 discharges from the hospital (20.4%) were associated with obesity, but only 512 discharges (1.7%) indicated obesity as a diagnosis. An obesity diagnosis identified only 5.5% of inpatient days for obese inpatients. Obese patients with an obesity diagnosis (Ob/Dx) had fewer hospital discharges per person and shorter lengths of stay than obese patients without an obesity diagnosis (Ob/No Dx). Patients with Ob/Dx had higher odds of mental health, endocrine, and musculoskeletal disorders than non-obese inpatients, but Ob/No Dx patients generally did not.

CONCLUSIONS

Inpatient obesity diagnoses underestimate inpatient utilization and misidentify patterns of care for obese children. Extreme caution is warranted when using obesity diagnoses to study healthcare utilization by obese children.

Which comes first: atypical antipsychotic treatment or cardiometabolic risk?

OBJECTIVE

To provide an overview for practicing clinicians on the pharmacological basis of cardiometabolic risk induced by antipsychotic drugs in patients with serious mental illness, to propose hypotheses to explain these risks and to give tips for managing cardiometabolic risk during antipsychotic treatment.

METHOD

A MEDLINE search using terms for atypical antipsychotics (including individual drug names), metabolic, cardiovascular, weight gain and insulin resistance, cross-referenced with schizophrenia was performed on articles published between 1990 and May 2008.

RESULTS

Strong evidence exists for significant cardiometabolic risk differences among several antipsychotic agents. Histamine H1 and serotonin 5HT2C antagonism are associated with risk of weight gain, but receptor targets for dyslipidemia and insulin resistance have not yet been identified. Convincing data indicate that hypertriglyceridemia and insulin resistance may occur in the absence of weight gain with certain antipsychotics.

CONCLUSION

Although lifestyle and genetics may contribute independent risks of cardiometabolic dysfunction in schizophrenia and other serious mental illness, antipsychotic treatment also represents an important contributor to risk of cardiometabolic dysfunction, particularly for certain drugs and for vulnerable patients. Mental health professionals must learn to recognize the clinical signposts indicating antipsychotic-related cardiometabolic problems to forestall progression to type II diabetes, cardiovascular events and premature death.

Side effects of second-generation antipsychotics: the experiences, views and monitoring practices of Australian child psychiatrists

OBJECTIVE

The aim of this study was to ascertain the experiences, views and monitoring practices of Australian child psychiatrists regarding the metabolic and other side effects of second-generation antipsychotics (SGAs).

METHOD

A 19-item questionnaire was posted to all members of the RANZCP Faculty of Child and Adolescent Psychiatry living in Australia.

RESULTS

Of the 290 eligible members of the Faculty of Child and Adolescent Psychiatry, 126 (43%) returned a useable survey. SGAs are commonly prescribed for a range of disorders. The majority of respondents expressed a high level of concern regarding weight gain and other metabolic side effects. Weight gain was the most frequently observed and monitored side effect in clinical practice. Other side effects were observed and monitored to a variable extent. Notably, monitoring practices did not parallel psychiatrists' reported level of concern or knowledge regarding weight gain and metabolic side effects,nor coincide with published recommendations.

CONCLUSIONS

Further research is required into the use, efficacy, side effects and monitoring of SGAs in children and adolescents, and there is a need to ensure that monitoring guidelines are implemented in clinical practice. This need is heightened by the likelihood that our data on clinicians' practice, which is based on their perceptions, may overestimate what actually occurs.
