Incidence, mortality and DALY trends in neurological disorders in children aged 0-14 years in Iran: Estimates from the Burden of Disease Study of the year 1990- 2019

The onset of mental disorders usually begins in childhood and carries a high individual and collective burden. The purpose of this study is to investigate the incidence, mortality, and burden of neurological disorders in children during the years 1990-2019 in Iran.

This study is a correlational analytical study during the years 1990-2019 in Iran. In this study, the indicators of incidence, death, prevalence, and disease burden (the index of years of life lost due to premature death and disability) were used. To examine the epidemiological indicators with the dimensions of the human development index, the concentration index was used. Analyzes were performed using Stata-14 software at a significance level of 0.05.

The highest incidence of neurological disorders in both sexes is related to 2019 (8444.82 per 100000) and the highest prevalence of neurological disorders in Iran is related to 1998 (17549.2 per 100000). The most years of life lost due to premature death are related in 1990, it was (218/58 per 100,000). The concentration index for incidence was -0.018 (-0.029, -0.007), death -0.15 (-0.202, -0.11), and prevalence -0.02 (-0.034, -0.005), which shows that incidence, death, and prevalence are more concentrated in years It has been that the socio-economic situation has been weaker. A significant relationship was observed between the death rate caused by neurological disorders and the dimensions of human development. Considerably, with the increase in life expectancy, average years of education, and gross national income, the death rate due to neurological disorders in children decreases significantly.

Considering that from 2015 to 2019, we have seen an increasing trend, therefore attention should be paid to the factors related to the occurrence of these disorders in children, and since the increase in life expectancy and the level of education causes a decrease in the mortality associated with these disorders, attention Improving these indicators can be effective in reducing the mortality of these children.
