bookPart Transtorno de déficit de atenção e hiperatividade e outros transtornos do neurodesenvolvimento(2019) POLANCZYK, Guilherme Vanoni; ROHDE, Luis Augusto; SUGAYA, Luísa Shiguemi; OLIVEIRA, Jordana Verano de- Psychiatric disorders and mental health treatment in American Indians and Alaska Natives: results of the National Epidemiologic Survey on Alcohol and Related Conditions(2016) HEART, Maria Yellow Horse Brave; LEWIS-FERNANDEZ, Roberto; BEALS, Janette; HASIN, Deborah S.; SUGAYA, Luisa; WANG, Shuai; GRANT, Bridget F.; BLANCO, CarlosTo examine the prevalence of common psychiatric disorders and associated treatment-seeking, stratified by gender, among American Indians/Alaska Natives and non-Hispanic whites in the United States. Lifetime and 12-month rates are estimated, both unadjusted and adjusted for sociodemographic correlates. Analyses were conducted with the American Indians/Alaska Native (n = 701) and Non-Hispanic white (n = 24,507) samples in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions [(NESARC) n = 43,093]. Overall, 70 % of the American Indian/Alaska Native men and 63 % of the women met criteria for at least one Diagnostic and Statistical Manual-IV lifetime disorder, compared to 62 and 53 % of Non-Hispanic white men and women, respectively. Adjusting for sociodemographic correlates attenuated the differences found. Nearly half of American Indians/Alaska Natives had a psychiatric disorder in the previous year; again, sociodemographic adjustments explained some of the differences found. Overall, the comparisons to non-Hispanic whites showed differences were more common among American Indian/Alaska Native women than men. Among those with a disorder, American Indian/Alaska Native women had greater odds of treatment-seeking for 12-month anxiety disorders. As the first study to provide national estimates, by gender, of the prevalence and treatment of a broad range of psychiatric disorders among American Indians/Alaska Natives, a pattern of higher prevalence of psychiatric disorder was found relative to Non-Hispanic whites. Such differences were more common among women than men. Prevalence may be overestimated due to cultural limitations in measurement. Unmeasured risk factors, some specific to American Indians/Alaska Natives, may also partially explain these results.
bookPart Transtornos alimentares(2017) MORIKAWA, Márcia; SUGAYA, Luisa Shiguemi- Children and adolescents' emotional problems during the COVID-19 pandemic in Brazil(2023) ZUCCOLO, Pedro Fonseca; CASELLA, Caio Borba; FATORI, Daniel; SHEPHARD, Elizabeth; SUGAYA, Luisa; GURGEL, Wagner; FARHAT, Luis Carlos; ARGEU, Adriana; TEIXEIRA, Monike; OTOCH, Luara; V, Guilherme PolanczykBrazil has been severely affected by the COVID-19 pandemic with one of the largest numbers of youth impacted by school closure globally. This longitudinal online survey assessed emotional problems in children and adolescents aged 5-17 years living in Brazil during the COVID-19 pandemic. Recruitment occurred between June to November 2020 and participants were invited for follow-up assessments every 15 days until June 2021. Participants were 5795 children and adolescents living across the country with mean age of 10.7 (SD 3.63) years at recruitment; 50.5% were boys and 69% of white ethnicity. Weighted prevalence rates of anxiety, depressive and total emotional symptoms at baseline were 29.7%, 36.1% and 36%, respectively. Longitudinal analysis included 3221 (55.6%) participants and revealed fluctuations in anxiety and depressive symptoms during one year follow-up, associated with periods of social mobility and mortality. Emotional problems significantly increased in July and September 2020 and decreased from December 2020 to February 2021 and then significantly increased in May 2021 relative to June 2020. Older age, feeling lonely, previous diagnosis of mental or neurodevelopmental disorder, previous exposure to traumatic events or psychological aggression, parental psychopathology, and sleeping less than 8/h a day were associated with increased rates of anxiety and depressive symptoms at baseline and over time. Food insecurity and less social contact with family and peers were associated with baseline anxiety and depressive symptoms, and lowest socio-economic strata, chronic disease requiring treatment and family members physically ill due to COVID-19 were associated with increasing rates over time. The pandemic severely affected youth, particularly those from vulnerable populations and in moments of increased mortality and decreased social mobility. Results underscore the need for allocation of resources to services and the continuous monitoring of mental health problems among children and adolescents.
- Efficacy and safety of methylphenidate and behavioural parent training for children aged 3-5 years with attentiondeficit hyperactivity disorder: a randomised, double-blind, placebo-controlled, and sham behavioural parent training-controlled trial(2022) SUGAYA, Luisa Shiguemi; SALUM, Giovanni Abrahao; GURGEL, Wagner de Sousa; MORAIS, Erika Mendonca de; PRETTE, Giovana Del; PILATTI, Caroline Drehmer; DALMASO, Bianca Batista; LEIBENLUFT, Ellen; ROHDE, Luis Augusto; POLANCZYK, Guilherme VanoniBackground There is insufficient evidence to support treatment recommendations for preschool children aged 3-5 years with attention-deficit hyperactivity disorder (ADHD). We aimed to investigate the efficacy and safety of methylphenidate and behavioural parent training in reducing the frequency and severity of symptoms and improving global functioning in preschool children with ADHD. Methods We did an 8-week, randomised, double-blind, placebo-controlled and sham behavioural parent trainingcontrolled clinical trial (the MAPPA Study) in children aged 3-5 years with moderate-to-severe ADHD. The trial was conducted at the Institute of Psychiatry, Hospital das Clinicas, University of Sao Paulo Medical School, Sao Paulo, Brazil. Participants were randomly assigned (1:1:1) to receive immediate-release methylphenidate plus educational intervention (sham behavioural parent training), placebo medication plus behavioural parent training, or placebo medication plus educational intervention. Randomisation was done by an independent research manager by use of a permuted block randomisation procedure. Parents, teachers, study staff, and evaluators remained masked to group allocation. Methylphenidate and placebo were titrated to a maximum dose of 1 center dot 25 mg/kg per day administered orally twice daily, and behavioural parent training and the educational intervention were delivered weekly through 90 min sessions with both the child and parent, conducted by two psychologists or learning therapists. The primary outcomes were parents' and teachers' composite scores of the Swanson, Nolan, and Pelham-IV scale (SNAP-IV-P/T), the Clinical Global Impressions Severity (CGI-S) scale, and the Children's Global Assessment Scale (CGAS). This trial is registered with ClinicalTrials.gov, NCT02807870, and is now complete. All participants were invited to participate in an open observational follow-up, which is ongoing. Findings Between Aug 21, 2016, and Oct 21, 2019, 153 children were randomly assigned to receive methylphenidate plus the educational intervention (n=51), placebo plus behavioural parent training (n=51), or placebo plus the educational intervention (n=51). Nine (6%) children discontinued treatment. All participants were included in the intention-to-treat analysis. Children in the methylphenidate plus educational intervention group showed greater reductions in the SNAP-IV-P/T (endpoint mean difference -3 center dot 93 [95% CI -7 center dot 14 to -0 center dot 73], p=0 center dot 049; effect size -0 center dot 55 [95% CI -0 center dot 99 to -0 center dot 10]) and CGI-S scores (endpoint mean difference -0 center dot 49 [-0 center dot 82 to -0 center dot 17], p=0 center dot 0088; effect size -0 center dot 70 [- 1 center dot 16 to -0 center dot 24]) and a greater increase in CGAS scores ( endpoint mean difference 5 center dot 25 [95% CI 2 center dot 09 to 8 center dot 40], p=0 center dot 0036; effect size 0 center dot 80 [95% CI 0 center dot 32 to 1 center dot 28]) than children in the placebo plus educational intervention group. Children in the placebo plus behavioural parent training group did not have significantly different SNAP-IV-P/T scores (endpoint mean difference -3 center dot 18 [95% CI -6 center dot 38 to 0 center dot 02], p=0 center dot 077; effect size -0 center dot 44 [95% CI -0 center dot 89 to 0 center dot 003]) or CGI-S scores (endpoint mean difference -0 center dot 35 [-0 center dot 68 to -0 center dot 03], p=0 center dot 052; effect size -0 center dot 50 [-0 center dot 96 to -0 center dot 04]) compared to children in the placebo plus educational intervention group, but they had a greater increase in CGAS scores compared to the placebo plus educational inter-vention group (endpoint mean difference 3 center dot 69 [0 center dot 53 to 6 center dot 85], p=0 center dot 033; effect size 0 center dot 56 [0 center dot 08 to 1 center dot 04]). Children in the methylphenidate plus educational intervention versus placebo plus behavioural parent training group did not have statistically or clinically significant differences in primary outcomes. Children in the methylphenidate plus educational intervention group had more mild adverse events than the other two groups, and there were no between-group differences for moderate or severe adverse events. Interpretation Methylphenidate was effective in reducing ADHD symptoms and improving functionality, and behavioural parent training was effective in improving functionality for preschool children with ADHD after 8 weeks of treatment.
bookPart transtornos disruptivos do comportamento(2021) SUGAYA, Luísa Shiguemi; GURGEL, Wagner de Sousa; POLANCZYK, Guilherme Vanoni- Validation of an irritability measure in preschoolers in school-based and clinical Brazilian samples(2022) SUGAYA, Luisa Shiguemi; KIRCANSKI, Katharina; STRINGARIS, Argyris; POLANCZYK, Guilherme V.; LEIBENLUFT, EllenThe Affective Reactivity Index (ARI) is an irritability measure with good psychometric properties. However, there are no published studies in preschool children, an important population in which to differentiate normative from non-normative irritability. The goal of this study was to validate the ARI in preschoolers. Two samples were included: a school-based sample (N = 487, mean age = 57.80 +/- 7.23 months, 52.8% male) and a clinical sample of children with Attention Deficit Hyperactivity Disorder (ADHD; N = 153, mean age = 60.5 +/- 7.6 months, 83.7% males). Confirmatory factor analysis assessed ARI unidimensionality. ARI criterion validity was tested through comparison to other scales measuring irritability, related constructs, and other aspects of psychopathology. Test-retest reliability was assessed in the school-based sample. Analyses confirmed a single-factor structure and good internal consistency. The ARI showed stronger correlations with irritability measures than with measures of other constructs. In the clinical sample, ADHD children with comorbid disruptive behavior disorders had higher ARI scores than those without this comorbidity. In the school-based sample, test-retest reliability was moderate. This is the first study to demonstrate ARI validity and reliability in preschoolers. The scale performed well in both school-based and clinical samples. Having a concise and validated irritability measure for preschoolers may facilitate both clinical assessment and research on early irritability.
bookPart Distúrbios psiquiátricos mais comuns na infância e adolescência(2016) POLANCZYK, Guilherme Vanoni; MORAIS, Érica Mendonça de; SUGAYA, LuisabookPart Impacto na saúde mental nas crianças e adolescentes na pandemia da COVID-19(2021) CASELLA, Caio Borba; SUGAYA, Luisa; POLANCZYK, Guilherme V.- Annual Research Review: A meta-analysis of the worldwide prevalence of mental disorders in children and adolescents(2015) POLANCZYK, Guilherme V.; SALUM, Giovanni A.; SUGAYA, Luisa S.; CAYE, Arthur; ROHDE, Luis A.BackgroundThe literature on the prevalence of mental disorders affecting children and adolescents has expanded significantly over the last three decades around the world. Despite the field having matured significantly, there has been no meta-analysis to calculate a worldwide-pooled prevalence and to empirically assess the sources of heterogeneity of estimates. MethodsWe conducted a systematic review of the literature searching in PubMed, PsycINFO, and EMBASE for prevalence studies of mental disorders investigating probabilistic community samples of children and adolescents with standardized assessments methods that derive diagnoses according to the DSM or ICD. Meta-analytical techniques were used to estimate the prevalence rates of any mental disorder and individual diagnostic groups. A meta-regression analysis was performed to estimate the effect of population and sample characteristics, study methods, assessment procedures, and case definition in determining the heterogeneity of estimates. ResultsWe included 41 studies conducted in 27 countries from every world region. The worldwide-pooled prevalence of mental disorders was 13.4% (CI 95% 11.3-15.9). The worldwide prevalence of any anxiety disorder was 6.5% (CI 95% 4.7-9.1), any depressive disorder was 2.6% (CI 95% 1.7-3.9), attention-deficit hyperactivity disorder was 3.4% (CI 95% 2.6-4.5), and any disruptive disorder was 5.7% (CI 95% 4.0-8.1). Significant heterogeneity was detected for all pooled estimates. The multivariate metaregression analyses indicated that sample representativeness, sample frame, and diagnostic interview were significant moderators of prevalence estimates. Estimates did not vary as a function of geographic location of studies and year of data collection. The multivariate model explained 88.89% of prevalence heterogeneity, but residual heterogeneity was still significant. Additional meta-analysis detected significant pooled difference in prevalence rates according to requirement of funcional impairment for the diagnosis of mental disorders. ConclusionsOur findings suggest that mental disorders affect a significant number of children and adolescents worldwide. The pooled prevalence estimates and the identification of sources of heterogeneity have important implications to service, training, and research planning around the world.
