Aim: To use the capture–recapture method to estimate the number of street children and adolescents in Maceió and Arapiraca, north‐east Brazil, and describe the characteristics of the two populations. Methods: The number of children and adolescents on the street in Maceió and Arapiraca was estimated using the multi‐list capture–recapture method. Two street surveys and an official list from the social services department were compared. The characteristics of the children were recorded during the street surveys using a questionnaire. Results: The estimated number of street children and adolescents was 5225 in Maceió and 1191 in Arapiraca. According to the official records, the population registered was 565 and 157, respectively. Most individuals were male (71.4% and 71.8%, respectively). They still maintain contact with their families (85.5% in Maceió and 89.6% in Arapiraca) and attend school regularly (43.4% and 49.7%). Drug use was admitted by 46.9% of the individuals in Maceió and by 26.9% in Arapiraca. In both cities, glue inhalation, associated or not with other drugs, was most frequently cited. Conclusions: Children and adolescents on the streets are a common and underestimated occurrence in Maceió and Arapiraca. They have similar characteristics to street children from other countries and other cities in Brazil. The method of capture–recapture seems to be suited to study populations such as street children. 相似文献

BACKGROUND: Traditionally, autism and specific language impairment (SLI) have been regarded as distinct disorders but, more recently, evidence has been put forward for a closer link between them: a common set of language problems, in particular receptive language difficulties and the existence of intermediate cases including pragmatic language impairment. The present study aimed to examine the prevalence of autism spectrum disorders in a large sample of adolescents with a history of SLI. METHOD: The presence of autism spectrum disorders was examined in seventy-six 14-year-olds with a confirmed history of SLI. A variety of instruments were employed, including the Autism Diagnostic Interview-Revised (ADI-R), the Autism Diagnostic Observation Schedule (ADOS) and the Family History Interview (FHI). RESULTS: The prevalence of autism spectrum disorders in young people with SLI was found to be 3.9%, about 10 times what would be expected from the general population. In addition, a much larger number of young people with a history of SLI showed only some autism spectrum symptoms or showed them in a mild form. CONCLUSIONS: Young people with SLI have an increased risk of autism. The magnitude of this risk is considerable. In addition, a larger proportion (a quarter of individuals) present with a number of behaviours consistent with autism spectrum disorders. 相似文献

OBJECTIVE: For both paediatricians and child psychiatrists, referrals to assess possible autistic spectrum disorders (ASD) are increasing. This study examines current practices of medical specialists in the assessment of these disorders. METHODS: An anonymous, self-report questionnaire was sent to all Queensland paediatricians and child psychiatrists. The survey elicited frequencies of consultation for ASD, diagnostic method, advice provided and perceived adequacy of training for this work. RESULTS: Responses were received from 79 (85%) eligible paediatricians and 26 (58%) eligible child psychiatrists. For one-third of all clinicians, new consultations for possible ASD occurred as often as 2-3 times per week. Most specialists approached the clinical diagnosis of ASD by considering history from different sources and professional assessments. Paediatricians (86%) were more likely than child psychiatrists (62%) to request genetic studies for children with severe autism (P = 0.01). Both general paediatricians and developmental paediatricians perceived level of training for possible ASD consultations was significantly worse than child psychiatrists (P < 0.001 and P = 0.02, respectively), but no difference was found between paediatric groups (P = 0.27). Perceived adequacy of specialist training was not associated with length of experience in clinical practice. CONCLUSION: Medical practice in Queensland around diagnosis of ASD is characterized by considerable variability. There is still a long way to go if we are to achieve consistency around medical issues of organic diagnosis and practices impacting on health as well as consideration of differential developmental diagnoses. The finding that recently trained paediatricians felt just as unprepared for this work as their older colleagues suggests that the graduate training response to this 'new morbidity' has not been adequate. 相似文献

Aim
To quantitatively examine the influence of study methodology and population characteristics on prevalence estimates of autism spectrum disorders.Methods
Electronic databases and bibliographies were searched and identified papers evaluated against inclusion criteria. Two groups of studies estimated the prevalence of typical autism and all autism spectrum disorders (ASD). The extent of variation among studies and overall prevalence were estimated using meta‐analysis. The influence of methodological factors and population characteristics on estimated prevalence was investigated using meta‐regression and summarised as odds ratios (OR).Results
Forty studies met inclusion criteria, of which 37 estimated the prevalence of typical autism, and 23 the prevalence of all ASD. A high degree of heterogeneity among studies was observed. The overall random effects estimate of prevalence across studies of typical autism was 7.1 per 10 000 (95% CI 1.6 to 30.6) and of all ASD was 20.0 per 10 000 (95% CI 4.9 to 82.1). Diagnostic criteria used (ICD‐10 or DSM‐IV versus other; OR = 3.36, 95% CI 2.07 to 5.46), age of the children screened (OR = 0.91 per year, 95% CI 0.83 to 0.99), and study location (e.g. Japan versus North America; OR = 3.60, 95% CI 1.73 to 7.46) were all significantly associated with prevalence of typical autism. Diagnostic criteria, age of the sample, and urban or rural location were associated with estimated prevalence of all ASD.Conclusions
Sixty one per cent of the variation in prevalence estimates of typical autism was explained by these models. Diagnostic criteria used, age of children screened, and study location may be acting as proxies for other study characteristics and require further investigation. 相似文献6.
OBJECTIVE: Recent data from Education Queensland has identified rising numbers of children receiving diagnoses of autistic spectrum disorder (ASD). Faced with funding diagnostic pressures, in clinical situations that are complex and inherently uncertain, it is possible that specialists err on the side of a positive diagnosis. This study examines the extent to which possible overinclusion of ASD diagnosis may exist in the presence of uncertainty and factors potentially related to this practice in Queensland. METHODS: Using anonymous self-report, all Queensland child psychiatrists and paediatricians who see paediatric patients with development/behavioural problems were surveyed and asked whether they had ever specified an ASD diagnosis in the presence of diagnostic uncertainty. Using logistic regression, elicited responses to the diagnostic uncertainty questions were related to other clinical- and practice-related characteristics. RESULTS: Overall, 58% of surveyed psychiatrists and paediatricians indicated that, in the face of diagnostic uncertainty, they had erred on the side of providing an ASD diagnosis for educational ascertainment and 36% of clinicians had provided an autism diagnosis for Carer's Allowance when Centrelink diagnostic specifications had not been met. CONCLUSION: In the absence of definitive biological markers, ASD remains a behavioural diagnosis that is often complex and uncertain. In response to systems that demand a categorical diagnostic response, specialists are providing ASD diagnoses, even when uncertain. The motivation for this practice appears to be a clinical risk/benefit analysis of what will achieve the best outcomes for children. It is likely that these practices will continue unless systems change eligibility to funding based on functional impairment rather than medical diagnostic categories. 相似文献

OBJECTIVE: To establish a community database for children with autism spectrum disorder (ASD) to determine prevalence and identify subgroups based on key intellectual, clinical and family parameters. METHODS: Data were collected for children previously diagnosed with an ASD in the Barwon region using parental interview and review of the child's paediatric and psychological records. Preschool diagnoses were typically made by specialist psychologists and school-age diagnoses made by a multidisciplinary team. RESULTS: One hundred and seventy-seven children in the Barwon region were identified as having ASD (82% response rate). The prevalence of ASD was one per 255 children aged two to 17 years. The prevalence increased 10 fold over a 16-year period and this increase was relatively even across all levels of child intellectual functioning. Forty-two percent of children were intellectually disabled (IQ < 70) and performance IQ was significantly higher than verbal IQ but typical block design-comprehension subtest patterns were not common. Nine sibling pair families were identified, 24% were labelled as having attention deficit hyperactivity disorder (ADHD), 6% had epilepsy, and 18.3% were macrocephalic where data were available. Family difficulty was associated with the degree of obsessions/rituals, frequency and intensity of anger/aggression, and ADHD but overall was not associated with the child's intellectual status. CONCLUSIONS: The relatively rapid increase in prevalence is consistent with overseas studies and suggests significant changes in diagnostic criteria, increasing community awareness and the need for support at all levels of intellectual functioning. Increased occurrence in siblings and relatives gives further evidence for a genetic cause. 相似文献

Using self-report to identify the broad phenotype in parents of children with autistic spectrum disorders: a study using the Autism-Spectrum Quotient 总被引:15,自引:0,他引:15

Background: The concept of the 'broad phenotype' of autism refers to the finding that relatives of people with autism often have mild forms of autistic-like characteristics, such as social and communicative difficulties. This study used the Autism Spectrum Quotient (AQ), a questionnaire devised to assess features of the broad phenotype in adults, with parents of people with autism, to see whether they would be more likely to obtain extreme scores than a control group.
Methods: The AQ was administered to parents of 69 people with an autism spectrum disorder and parents of 52 controls.
Results: On two of the five subscales of the AQ, social skills and communication, parents of people with autism obtained higher scores than control parents. The other three scales, attention to detail, attention switching, and imagination, did not differentiate groups. The correlation between social skills and communication scales was .663. The scales can be combined to give an index of broad phenotype.
Conclusions: The AQ appears to be sensitive to the broad phenotype, provided attention is restricted to the social skills and communication scales. 相似文献

Background: Children with autism spectrum disorders often present with comorbid anxiety disorders that cause significant functional impairment. This study tested a modular cognitive behavioral therapy (CBT) program for children with this profile. A standard CBT program was augmented with multiple treatment components designed to accommodate or remediate the social and adaptive skill deficits of children with ASD that could pose barriers to anxiety reduction.
Method: Forty children (7–11 years old) were randomly assigned to 16 sessions of CBT or a 3-month waitlist (36 completed treatment or waitlist). Therapists worked with individual families. The CBT model emphasized behavioral experimentation, parent-training, and school consultation. Independent evaluators blind to treatment condition conducted structured diagnostic interviews and parents and children completed anxiety symptom checklists at baseline and posttreatment/postwaitlist.
Results: In intent-to-treat analyses, 78.5% of the CBT group met Clinical Global Impressions-Improvement scale criteria for positive treatment response at posttreatment, as compared to only 8.7% of the waitlist group. CBT also outperformed the waitlist on diagnostic outcomes and parent reports of child anxiety, but not children's self-reports. Treatment gains were maintained at 3-month follow-up.
Conclusions: The CBT manual employed in this study is one of the first adaptations of an evidence-based treatment for children with autism spectrum disorders. Remission of anxiety disorders appears to be an achievable goal among high-functioning children with autism. 相似文献

Thalassemia is one of the most common hereditary disorders in the Mediterranean region and studies have shown that the prevalence of β-thalassemia trait is high in the southern part of Turkey. Gaziantep is a city located near this region and, therefore, the authors investigated the prevalence and hematological characteristics of the β-thalassemia traits in primary school students in Gaziantep. Sixty primary schools were selected from a list of all primary schools using a systematic sampling method. Data were collected by a face-to-face questionnaire. Osmotic fragility testing (OFT) using single-tube 0.36% NaCl solution was used for the screening of β-thalassemia. Students who were positive in regard to OFT went through a series of testing, including a complete blood count, serum ferritin levels, serum iron, and hemoglobin electroforesis. Chi-square test was used in statistical analysis. Of the 2439 students enrolled to the study from the selected 60 classrooms, 1353 (55.5%) were male and 1086 (44.5%) were female. The OFT was positive in 115 (4.7%) of the participants. CEA and confirmatory HPLC results of the students who were positive OFT indicated that 70 (60.8%) had normal results, 33(28.7%) showed high HbA2 levels, 7 (6.1%) showed high HbA2 and HbF levels, 5(5.2%) showed high HbA2 and Fe-deficiency anemia, and none showed increased HbF levels. The overall prevalence of β-thalassemia trait was 1.84%. No gender differentials and highest rates among the Kahramanmaras (3.5%) and Sanliurfa (1.7%) born students were the other significant findings of this study. Implementation of a routine carrier-screening program offering genetic counseling, prenatal diagnosis, and selective termination of affected fetuses would be a wise approach to eliminate this disease from the region. 相似文献

??Autism spectrum disorder??ASD??is a severe neurodevelopmental disease. At the present time, approved and recommended treatments for ASD are mainly based on rehabilitation and educational interventions. ASD is defined by core behavioural impairments, but gastrointestinal??GI?? symptoms are commonly reported. And the GI symptoms are considered to relate to the dysbiosis of gut microbiota and a disorder of the microbiota-gut-brain axis. The alterations of epithelial integrity, immune function and neurotransmitter lead to GI symptoms and autistic behaviors associated with dysbiosis of the gut microbiota. Probiotics can be useful to restore the microbiota balance in the intestine??to alleviate GI symptoms and ameliorate behavioural symptoms associated with some ASD. Although further research and rigorous clinical trial should be required to study the effect and mechanism of probiotics in the treatment of ASD??they can be considered potential effect on ASD. 相似文献

Background: In Latin America, there is limited research on the prevalence of mental disorders in children and adolescents. This Chilean survey is the first national representative survey in the Latin American region to examine the prevalence of Diagnostic and Statistical Manual-IV (DSM-IV) psychiatric disorders in the region in children and adolescents. Methods: Subjects aged 4-18 were selected using a stratified multistage design. The Diagnostic Interview Schedule for Children version IV (DISC-IV) was used to obtain 12-month DSM-IV diagnoses of affective, anxiety, conduct and substance use disorders, and supplemented with questionnaires examining family risk factors, family income, and service utilization. The parent or the primary caretaker was interviewed for children, aged 4-11, using the DISC-IV; however, adolescents, aged 12-18, were directly interviewed. Results: A sample of 1558 children and adolescents was evaluated. Using the most stringent DISC-IV impairment algorithm, the prevalence rate for any psychiatric disorders was 22.5% (19.3% for boys and 25.8% for girls). The prevalence rate was higher among the children, aged 4-11, in comparison with adolescents, aged 12-18 (27.8% and 16.5%, respectively). Less than half of the subjects in need of services sought some form of assistance. Nearly a quarter of those using services did not present with a psychiatric diagnosis in the past year. Comorbidity was found in 24.8% of those with a disorder, but only 6.3% had three or more diagnoses. Conclusions: The prevalence of psychiatric disorders in Chile is high among children and adolescents. This study highlights the increasing need to reevaluate mental health services provided to children and adolescents in Latin America. 相似文献

The developmental disorders of childhood autistic, developmental language, reading (dyslexia), and attention deficit-hyperactivity disorders-manifest with deficits in the traditional behavioral domains of cognition, language, visual-spatial function, attention, and socialization. However, none of these disorders has been associated with characteristic discrete focal lesions or recognized encephaloclastic processes. Developmental cognitive neuroscientists must therefore begin with the spectrum of sometimes divergent behaviors occurring within these disorders and work backward in an attempt to identify the responsible anomalous neural systems. Since the advent of "brain imaging" two decades ago, much effort has focused on identifying brain-behavior correlates in these disorders. The results of these neuropathologic, structural, and functional neuroimaging studies are presented and the reasons for the often divergent findings are discussed. As we approach the end of the Decade of the Brain, current neuroimaging techniques give us the technology for the first time to apply a fundamental cognitive approach to brain-behavior relationships in the developmental disorders, to eliminate the conglomeration of "apples and camels" phenomenon. Researchers are working together to create comparable protocols and to adhere to methods that can be replicated across sites. The future prospects for a greater understanding of the developmental disorders are now much brighter with neuroimaging technology. 相似文献

Background: Data from epidemiology have consistently highlighted a disparity between the true prevalence of childhood psychiatric disorders and their recognition as defined by receiving a clinical diagnosis. Few studies have looked specifically at the level of unidentified autistic spectrum disorder (ASD) in the population. Method: Logistic regression was used to determine the behavioural traits associated with receiving a diagnosis of ASD using data from the Avon Longitudinal Study of Parents and Children (ALSPAC). A composite score was derived to measure levels of autistic traits; undiagnosed children with scores matching those diagnosed with ASD were identified. Levels of educational provision beyond that provided by standard schooling were examined. Results: Fifty‐five percent of children with autistic traits at the same levels as those who had an autism diagnosis had not been identified as needing extra support from education or specialised health services. Of those who were identified as having special needs, 37.5% had been formally diagnosed with an ASD. For children with impairment at the same level as that associated with Asperger’s syndrome, 57% had no special provision at school, and were not accessing specialised health services. Twenty‐six percent of those who did have special provision at school had an ASD diagnosis. Conclusions: The results suggest that there may be a substantial proportion of children on the autistic spectrum who are never identified by services. 相似文献

Background: This study compared two interventions for improving the social skills of high functioning children with autism spectrum disorders in general education classrooms. One intervention involved a peer‐mediated approach (PEER) and the other involved a child‐assisted approach (CHILD). Method: The two interventions were crossed in a 2 × 2 factorial design yielding control, PEER, CHILD, and both PEER and CHILD conditions. Sixty children participated from 56 classrooms in 30 schools. Interventions involved 12 sessions over 6 weeks, with a 3‐month follow‐up. Outcome measures included self, peer and teacher reports of social skills and independent weekly observations of children on their school playground over the course of the intervention. Results: Significant improvements were found in social network salience, number of friendship nominations, teacher report of social skills in the classroom, and decreased isolation on the playground for children who received PEER interventions. Changes obtained at the end of the treatment persisted to the 3‐month follow‐up. Conclusions: These data suggest that significant improvements can be made in peer social connections for children with autism spectrum disorders in general education classrooms with a brief intervention, and that these gains persist over time. 相似文献

Objectives: The purpose of this study was to examine group differences and relationships with later developmental level and autism symptoms using a new clinical tool developed to measure repetitive and stereotyped movements (RSM) in young children.
Method: Videotaped behavior samples using the Communication and Symbolic Behavior Scales Developmental Profile (CSBS; Wetherby & Prizant, 2002 ) were coded for children with autism spectrum disorders (ASD; n = 50), developmental delays without ASD (DD; n = 25), and typical development (TD; n = 50) between 18 and 24 months of age.
Results: Children with ASD demonstrated significantly higher rate and larger inventory of RSM with objects and body during a systematic behavior sample than both the DD and TD groups. Measures of RSM were related to concurrent measures of social communication and predicted developmental outcomes and autism symptoms in the fourth year for the ASD group. None of the correlations between RSM and autism symptoms remained significant when controlling for CSBS Symbolic level. RSM with objects predicted unique variance in the severity of autism symptoms in the fourth year beyond that predicted by social communication measures alone.
Conclusions: This study provides support for the diagnostic significance of RSM in children under 24 months of age and documents the utility of this RSM measurement tool as a companion to the CSBS. 相似文献

BACKGROUND: Mycoplasma pneumoniae is a well known causative agent of infection in childhood but clinical presentation may be variable. History and physical examination may not be so helpful for the diagnosis. It is difficult to culture this infectious agent, with the culture technique for the multiplication of the organism for routine investigation hard to obtain. The determination of exposure and prevalence of the disease of any region should be helpful for clinical diagnosis. In this study, we aimed to determine the seroprevalence of M. pneumoniae in children aged 0-14 years in Diyarbakir and establish the distribution of infection prevalence of various age groups of children. METHODS: Thirty streets were determined according to the cluster method for the 0-6 years age group. In this age group, a total of 180 blood samples were collected; so that there were 30 samples for each age. For children aged 7-14 years, elementary school children were selected. There were 70 elementary schools in the city and 14 schools were randomly selected according to the randomized numbers table with a 20% sample. Finally, 276 blood samples were collected. Mycoplasma pneumoniae was determined by using the enzyme immunoassay method. For this method MELOTEST Mycoplasma IgG reagent was used. RESULTS: The highest seropositivity rate was encountered at 10 years of age (65%) and lowest was at 2 years of age (0%). The overall M. pneumoniae seropositivity was 27% when all ages were considered together. The first 2 years of age excluded this rate and was 31.9%. A sudden increase of seropositivity was observed at 7 years of age. CONCLUSIONS: Increasing seroprevalence rates of M. pneumoniae after 2 years of age should alert clinicians to consider the organism in the differential diagnosis of infectious diseases in this age group. The low seroprevalence rates in the first 2 years of age was thought to be due to low risk of community-based spread of the organism in this age group. The most prominent increase in seroprevalence was at 10 years of age. This data indicated that M. pneumoniae should be kept in mind while making differential diagnosis of infections. The spreading of disease and community-based transmission is also important to consider. In our study, seroprevalence rates increased at 6 and 7 years of age, at the beginning of the school age as community-based transmission takes place most commonly in crowded circumstances. In conclusion, M. pneumoniae should be thought as an important infectious agent in childhood for all age groups. 相似文献

Prevalence of psychiatric diagnoses and the role of perceived impairment: findings from an adolescent community sample 总被引:9,自引:0,他引:9

The present study examined psychiatric functioning in a community sample of adolescents aged 14 to 17 years (average age of 15 years). We administered the Diagnostic Interview Schedule for Children-2.25 (DISC-2.25) to 1,201 adolescents and their mothers to obtain prevalence estimates of DSM-III-R disorders and the amount of perceived impairment associated with these disorders. While adolescent females reported a significantly higher prevalence of psychiatric disorders than males (15.5% vs. 8.5%), mothers indicated no sex difference. Compared with adolescent males, females had significantly higher rates of internalizing, anxiety. and depressive disorders. In contrast, the prevalence of externalizing disorders was significantly higher among adolescent males. The inclusion of an impairment criterion had a significant impact in reducing the prevalence rates of overall psychiatric disorders. This reduction occurred mainly through impairment's effects on internalizing disorders, specifically anxiety-based disorders (i.e., simple and social phobia). Given the limited research on the effect of impairment on the prevalence of adolescent psychiatric disorders, future work in this area seems warranted. 相似文献
