Use of allied-health services and medication among adults with ASD in Latin America / Andy TORRES in Autism Research, 14-10 (October 2021)  

Public ISBD [article]  inAutism Research > 14-10 (October 2021) . - p.2200-2211 Titre : Use of allied-health services and medication among adults with ASD in Latin America Type de document : texte imprimé Auteurs : Andy TORRES, Auteur ; Denise LECUSAY, Auteur ; Daniel VALDEZ, Auteur ; Analia ROSOLI, Auteur ; Gabriela GARRIDO, Auteur ; Sebastián CUKIER, Auteur ; Cristiane S. PAULA, Auteur ; Ricardo GARCIA, Auteur ; Alexia RATTAZZI, Auteur ; Cecilia MONTIEL-NAVA, Auteur Article en page(s) : p.2200-2211 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder/drug therapy  Autistic Disorder  Caregivers  Health Services  Humans  Latin America  Hispanics  allied health  autism  autism medication  health disparities Index. décimale : PER Périodiques Résumé : ASD is a neurodevelopmental disorder that affects people across the entire lifespan, yet most of the research identifying the health and medical needs for autistic individuals have been among minors. As individuals with ASD transition to emerging adulthood, the services, already limited, become less available. This study aimed to identify the use of services for Latin American adults on the spectrum. We surveyed 295 caregivers of adults with ASD from six Latin American countries. Comparing the results for all the possible services observed in this study, the adults in our sample were primarily underserved: 84.4%-95.9% were receiving zero hours per week, 3.7%-12.9% 1%-10 h, 0%-1.7% 11-20, and only 0%-1% above 20 h of services. Almost half of the sample used medication, and neurologists were the most consulted health providers. Next to inexistent health care usage in Latin American adults with ASD highlights socioeconomic and health disparities in service provision for ASD in the region. The lack of services places adults with ASD in Latin America at a higher risk of worse symptom severity than autistic adults from regions with broader access to services. LAY SUMMARY: This study aimed to identify the quantity of services received by adults with autism in Latin America. Most of our sample was not receiving health services yet almost half had access to medication. This could mean that adults with autism in Latin America are at higher risk for poorer health.

A later autism spectrum disorder diagnosis has been associated with negative consequences, as it might imply later access to services. This study aims to identify factors associated with the age of autism spectrum disorder diagnosis as reported by 2520 caregivers of autistic children from six Latin America and Caribbean Countries. Results indicate that on average, caregivers were concerned about their child?s development by 22 months of age; however, the diagnosis was 24 months later. Current age of autistic individuals, better language abilities, and having public health coverage increased the age of diagnosis. On the contrary, the presence of medical comorbidities, severity level, and type of diagnosis decreased the age of diagnosis. The age of diagnosis of autistic individuals in Latin America and Caribbean Countries corresponded to the start of formal schooling despite a much earlier age of first noticed developmental concern, highlighting the need to reduce this age gap and increase children s probability of benefiting from early intervention. Taken together, autism spectrum disorder personal/clinical characteristics and access to health service are the main determinants for the age of diagnosis. Lay abstract An earlier diagnosis of autism spectrum disorder might lead to earlier intervention. However, people living in Latin American and Caribbean countries do not have much knowledge about autism spectrum disorder symptoms. It has been suggested that the older a child is when diagnosed, the fewer opportunities he or she will have to receive services. We asked 2520 caregivers of autistic children in six different Latin America and Caribbean Countries, the child?s age when they noticed some developmental delays and their child?s age when they received their first autism spectrum disorder diagnosis. Results indicate that, on average, caregivers were concerned about their child?s development by 22 months of age; however, the diagnosis was received when the child was 46 months of age. In addition, older children with better language abilities and public health coverage (opposed to private health coverage) were diagnosed later. On the contrary, children with other medical problems and more severe behaviors received an earlier diagnosis. In our study, children were diagnosed around the time they entered formal schooling, delaying the access to early intervention programs. In summary, the characteristics of the autistic person and the type of health coverage influence the age of diagnosis in children living in Latin America and Caribbean Countries.

This cohort study aimed to estimate autism spectrum disorder prevalence in Chile by linking school registries with electronic health records. Probabilistic data linking was conducted between the 2021 Chilean school registry and 2003 2015 health records from the Araucania Sur Health Service. Bayesian prevalence estimation was used, considering variables such as age, sex, immigration status, ethnicity and rurality. Autism spectrum disorder prevalence across 29 health services was analysed for students aged 6 to 18 years. Regression models assessed unmet needs for special education services, validated using Araucania Sur Health Service health records. The study included 3,056,306 pupils (51.34% boys; mean age 11.6 years), with 14,549 having autism spectrum disorder. The national standardized school prevalence was 0.46%. Boys had 6 times higher odds of receiving special education services support than girls. In Araucania Sur Health Service, the adjusted clinical prevalence from health records was 1.22%. The Bayesian projected national autism spectrum disorder prevalence was 1.31%. This study, the largest of its kind in Latin America, revealed a higher autism spectrum disorder prevalence than previously reported, with one in 76 children affected. Disparities were observed across sex, ethnicity and health services.Lay abstract This project tried to understand how many children in Chile are affected by autism, as reliable data have been lacking not only in Chile but across much of Latin America. To do this, we carried out the largest autism prevalence study ever conducted in the region. We linked national school records from 2021 with over a decade of health records (2003-2015) from the Araucanía Sur Health Service in southern Chile. This allowed us to examine data from more than three million students aged 6 to 18 years across 29 health services. Our results revealed that around one in every 76 children may have autism - almost 3 times higher than what was reported in schools alone. We also found that boys were 6 times more likely than girls to receive special education support. Using advanced statistical modelling, we estimated a national autism prevalence rate of 1.31%. Importantly, we discovered disparities in diagnosis and access to support based on sex, ethnicity, immigration status and whether a child lived in a rural or urban area. These findings highlight the need for more inclusive and equitable approaches to autism identification and care across Chile. This research not only helps to fill a major data gap but also offers a model for how countries with limited resources can use existing administrative data to improve public health planning and educational support for children with autism.

Limited Sensitivity and Specificity of the Spanish Social Communication Questionnaire in a Clinic Sample in Quito, Ecuador / Jonathan SAFER-LICHTENSTEIN in Autism, 30-9 (September 2026)  

Public ISBD [article]  inAutism > 30-9 (September 2026) . - p.2427-2431 Titre : Limited Sensitivity and Specificity of the Spanish Social Communication Questionnaire in a Clinic Sample in Quito, Ecuador Type de document : texte imprimé Auteurs : Jonathan SAFER-LICHTENSTEIN, Auteur ; Jenniffer VILLARREAL, Auteur ; Lucas FERNANDEZ, Auteur ; Mary TROXEL, Auteur Article en page(s) : p.2427-2431 Langues : Anglais (eng) Mots-clés : autism  Latin America  cross-cultural studies  global context  screening Index. décimale : PER Périodiques Résumé : Accurate identification of autism is critical for timely intervention, yet validated screening tools remain limited in Latin America. This study evaluated the psychometric properties of the Spanish-translated Social Communication Questionnaire (SCQ) in a clinic-based sample of children in Quito, Ecuador. Caregivers of 94 children aged 4-18 years completed the SCQ Lifetime form as part of a diagnostic evaluation that included cognitive testing, developmental history, and the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). Internal consistency of the SCQ was good (Cronbach’s α = .843). However, the SCQ showed poor diagnostic accuracy, with an area under the receiver operating characteristic curve (AUC) of .60. At the conventional SCQ cut score of 15, sensitivity and specificity were .56 and .60, respectively; using a lower cut score of 11 increased sensitivity (.72) but decreased specificity (.43). These findings indicate limited utility of the SCQ as a screening instrument for autism in this clinical context. Results align with other studies showing variability in SCQ performance across diverse populations and settings, highlighting the need for locally validated screening tools.Lay Abstract Early and accurate identification of autism helps children and families access helpful supports, yet most screening tools have been developed and tested mainly in English-speaking countries, and we know less about how well they work in Latin America. In this study, we examined how well a Spanish translation of the widely used Social Communication Questionnaire (SCQ) identified autism in a clinic in Quito, Ecuador. Caregivers completed the questionnaire as part of a full clinical evaluation by trained professionals. We found that the SCQ was not very accurate at distinguishing which children did or did not have autism in this setting, meaning it may not be reliable on its own for screening. These results suggest that screening tools should be carefully tested with local communities before widespread use and highlight the need for tools that better reflect the languages, cultures, and experiences of families.

Prevalence of child and adolescent mental disorders in Chile: a community epidemiological study / Benjamín VICENTE in Journal of Child Psychology and Psychiatry, 53-10 (October 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-10 (October 2012) . - p.1026-35 Titre : Prevalence of child and adolescent mental disorders in Chile: a community epidemiological study Type de document : texte imprimé Auteurs : Benjamín VICENTE, Auteur ; Sandra SALDIVIA, Auteur ; Flora DE LA BARRA, Auteur ; Robert KOHN, Auteur ; Ronaldo PIHAN, Auteur ; Mario VALDIVIA, Auteur ; Pedro RIOSECO, Auteur ; Roberto MELIPILLAN, Auteur Année de publication : 2012 Article en page(s) : p.1026-35 Langues : Anglais (eng) Mots-clés : Children  adolescent  epidemiology  mental disorders  prevalence  Latin America Index. décimale : PER Périodiques Résumé : 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.
