Using a systematic review, we synthesized estimates of the prevalence of autism worldwide. We examined factors accounting for variability in estimates and critically reviewed evidence relevant for hypotheses about biological or social determinants (viz., biological sex, sociodemographic status, ethnicity/race, and nativity) potentially modifying prevalence estimates of autism. We performed the search in November 2021 within Medline for studies estimating autism prevalence, published since our last systematic review in 2012. Data were extracted by two independent researchers. Since 2012, 99 estimates from 71 studies were published indicating a global autism prevalence that ranges within and across regions, with a median prevalence of 100/10,000 (range: 1.09/10,000 to 436.0/10,000). The median male-to-female ratio was 4.2. The median percentage of autism cases with co-occurring intellectual disability was 33.0%. Estimates varied, likely reflecting complex and dynamic interactions between patterns of community awareness, service capacity, help seeking, and sociodemographic factors. A limitation of this review is that synthesizing methodological features precludes a quality appraisal of studies. Our findings reveal an increase in measured autism prevalence globally, reflecting the combined effects of multiple factors including the increase in community awareness and public health response globally, progress in case identification and definition, and an increase in community capacity. Hypotheses linking factors that increase the likelihood of developing autism with variations in prevalence will require research with large, representative samples and comparable autism diagnostic criteria and case-finding methods in diverse world regions over time. LAY SUMMARY: We reviewed studies of the prevalence of autism worldwide, considering the impact of geographic, ethnic, and socioeconomic factors on prevalence estimates. Approximately 1/100 children are diagnosed with autism spectrum disorder around the world. Prevalence estimates increased over time and varied greatly within and across sociodemographic groups. These findings reflect changes in the definition of autism and differences in the methodology and contexts of prevalence studies.

Treated prevalence of and mental health services received by children and adolescents in 42 low-and-middle-income countries / Jodi MORRIS in Journal of Child Psychology and Psychiatry, 52-12 (December 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-12 (December 2011) . - p.1239-1246 Titre : Treated prevalence of and mental health services received by children and adolescents in 42 low-and-middle-income countries Type de document : Texte imprimé et/ou numérique Auteurs : Jodi MORRIS, Auteur ; Myron L. BELFER, Auteur ; Amy M. DANIELS, Auteur ; Alan J. FLISHER, Auteur ; Liesbet VILLE, Auteur ; Antonio LORA, Auteur ; Shekhar SAXENA, Auteur Année de publication : 2011 Article en page(s) : p.1239-1246 Langues : Anglais (eng) Mots-clés : Mental health services  access  treated prevalence  low- and middle-income countries Index. décimale : PER Périodiques Résumé : Background:  Little is known about the treated prevalence and services received by children and adolescents in low- and middle-income countries (LAMICs). The purpose of this study is to describe the characteristics and capacity of mental health services for children and adolescents in 42 LAMICs. Methods:  The World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS), a 155-indicator instrument developed to assess key components of mental health service systems, was used to describe mental health services in 13 low, 24 lower-middle, and 5 upper-middle-income countries. Child and adolescent service indicators used in the analysis were drawn from Domains 2 (mental health services), 4 (human resources), and 5 (links with other sectors) of the WHO-AIMS instrument. Results:  The median one-year treated prevalence for children and adolescents is 159 per 100,000 population compared to a treated prevalence of 664 per 100,000 for the adult population. Children and adolescents make up 12% of the patient population in mental health outpatient facilities and less than 6% in all other types of mental health facilities. Less than 1% of beds in inpatient facilities are reserved for children and adolescents. Training provided for mental health professionals on child and adolescent mental health is minimal, with less than 1% receiving refresher training. Most countries (76%) organize educational campaigns on child and adolescent mental health. Conclusions:  Mental health services for children and adolescents in low- and middle-income countries are extremely scarce and greatly limit access to appropriate care. Scaling up of services resources will be necessary in order to meet the objectives of the WHO Mental Health Gap Action (mhGAP) program which identifies increased services for the treatment of child mental disorders as a priority.
