Insights
The incidence of pediatric multiple sclerosis (MS) in Iran is high, increasing significantly from 2000 to 2019. Improved diagnostic practices likely contributed to detecting more cases in children.
Area of Science:
- Neurology
- Epidemiology
- Pediatrics
Background:
- Limited epidemiological data exists for pediatric multiple sclerosis (MS) in Iran.
- Understanding the incidence of pediatric MS is crucial for public health planning and resource allocation.
Purpose of the Study:
- To determine the incidence rate of pediatric multiple sclerosis (MS) in Iran over a 20-year period.
- To analyze trends and demographic factors associated with pediatric MS in Iran.
Main Methods:
- A retrospective study utilizing 20 years of data (2000-2019) from the Iranian Ministry of Health and Medical Education.
- Inclusion criteria: patients diagnosed with MS since 2000, born in 1982 or later.
- Data collected included age at diagnosis, gender, residency, and province; age-specific incidence rates were calculated.
Main Results:
- The study analyzed 4544 cases of pediatric MS between 2000 and 2019.
- The incidence rate of pediatric MS in Iran rose from 0.26 to 1.53 per 100,000 population during the study period.
- Most pediatric MS patients (97.1%) resided in urban areas, with a mean age at diagnosis of 14.3 years.
Conclusions:
- The incidence of pediatric multiple sclerosis (MS) in Iran is notably high.
- Advancements in diagnostic capabilities over the past decade have likely enhanced the detection of pediatric MS cases.
Objectives:
Due to a lack of data on pediatric multiple sclerosis (MS) epidemiology in Iran, this study aimed to determine the incidence rate of pediatric MS in Iran.
Materials & Methods:
All the data of the patients with MS registered in the Ministry of Health and Medical Education of Iran for 20 years were collected in this study; those born in 1982 and diagnosed with the disease and treated since 2000 were included in this study. Therefor The collected variables were patients' age at the time of diagnosis, gender, year of diagnosis, urban or rural residency, and province of residence. Additionally, age-specific incidence rates per 100,000 of the population were calculated.
Results:
This study was performed on 4544 cases of pediatric MS within 2000-2019, of which 997 patients (21.9%) were male. The mean age of the patients with MS at the time of diagnosis was 14.3±4.6 years, and 4414 children (97.1%) lived in urban areas. The incidence rate of pediatric MS in Iran during 20 years increased from 0.26 per 100,000 of the population in 2000 to 1.53 in 2019.
Conclusion:
The incidence of pediatric MS in Iran is high, and the development of diagnostic practices in the past decade in Iran has contributed to the detection of this high incidence.
