[Screening of the risk of mental and developmental disorders in children of early age in the Russian population (2017-2019)]. / Skrining riska vozniknoveniya narushenii psikhicheskogo razvitiya u detei rannego vozrasta (dannye po 9 regionam Rossii v 2017­2019 gg.).

OBJECTIVE: Screening of children 18-48 months of age at risk of mental and developmental disorders in the general population. MATERIAL AND METHODS: The survey was conducted by a continuous epidemiological method in primary health care institutions in the nine largest regions of Russia. For the period 2017-2019, 595 691 parents of children, aged 18-48 months, were surveyed. RESULTS AND CONCLUSION: The prevalence risk rate for mental and developmental disorders was determined as 1.307:10 000. The prevalence rate for mental and behavioural disorders (ICD-10) was 151:10 000. The analysis of the structure of mental and behavioural disorders was carried out. An increase in cases of pervasive developmental disorders (item F84) was detected - autism spectrum disorders (ASD) with an increase in the age of children. The prevalence of ASD under the age of 48 months was found to be 18:10 000, compared with 2015-2016 - 5:10 000 under the age of 24 months.

AIM: To screen infants of the general population for the risk of autism spectrum disorders (ASD). MATERIAL AND METHODS: The survey was conducted by a total epidemiological method in primary health care facilities in the three largest regions in Russia (Volgograd, Novosibirsk, Chelyabinsk regions). For the period 2015-2016, 74191 parents of children aged 16-24 months were questioned. RESULTS AND CONCLUSION: The prevalence of risk of ASD (a condition of a pre-illness) was 103.5 cases per 1000 of children aged 16-24 months. Some of the children at ASD risk had a preventive consultation with a psychiatrist, 36 children (0.5 per 1000 peers) had severe clinical disorders classified as F84 - 'Pervasive developmental disorders' of ICD-10 (F84.0; F84.1; F84.8). From the perspective of predicative and preventive medicine, children at risk require complex measures to prevent the onset of a mental disorder or worsening of the mental state of the child.
