RESUMO
OBJECTIVE: To examine the structural-dynamic trends in disability in children aged 0-14 and 15-17 in the Arkhangelsk region (AO) over the period 2010-2020. MATERIAL AND METHODS: The age-standardized rates of primary and total disability calculated on the basis of the official statistical data presented in the form No.19 «Statistics on Disabled Children¼ for 2010-2020 in AO excluding Nenets autonomous district.and Russian Federation (RF), section «Mental disorders and conduct disorder¼ (F00-F99 according to ICD-10) were used. Age-specific population data were taken from the Russian database on fertility and mortality. The methods of econometric and statistical analysis (the index method, the Irwin method, the Chow test) were used. RESULTS: In the Arkhangelsk Oblast, as well as in the whole country, there has been a growth in disability rates over the last decade. The level of the general children's disability in AO was lower than in the RF on the average by 25.7 (±3.45)%. The age groups 5-9 (6.03%) and 15-17 (3.70%) years contribute mostly to the ten-year trend in the overall rate of mental disabilities. The increase in childhood disability due to mental disorders was 13.96% over 2010-2019, with this increase being due to so-called 'other mental disorders' (all mental disorders other than mental retardation) by 27.29%, while the dynamic contribution of disability due to mental retardation (F70-F79) was negative (-13.32%). CONCLUSION: The dynamics of total disability in children due to mental disorders in the AO has a common with the Russian average upward trend at a lower level. The age groups 5-9 and 15-17 years old have the greatest significance for the dynamic changes in the general disability of children due to mental disorders. The leading nosological group responsible for the ten-year increase in disability due to mental disorders is «other mental disorders¼.
