Abstract:
Background:Globally the incidence of stroke is not decreasing, and the deaths and disabilities
caused by stroke is increasing every year, especially in low and low-middle income countries.
Long-term trends in stroke incidence in different populations have not been well characterized, largely
as a result of the complexities associated with population-based stroke surveillance.
Having reliable data on stroke morbidity and mortality, as well as periodic identification of long-term
trends will be important information for proper prevention planning in the population, monitoring the
disease and further improving the quality of health care.
Material and Method:A prospective cohort study has been conducted in adult citizens (972409 in
2019, 925367 in 2020) of 6 districts of Ulaanbaatar from the 1st of January, 2019 to 31st of December,
2020. All first-ever and recurrent stroke cases were included using special software, developed for
stroke registry, based on the WHO STEPS approach from participating radiology departments of state
hospitals, district hospitals, and some private hospitals. Information of stroke death was obtained
from forensic institute and state registration office of the capital city.
The trends of stroke incidence and mortality was compared to data between 1998-1999 and 2019-
2020 in UB.
Results:The age-standardized crude incidence rate per 100.000 person-years of stroke were
209.0/100.000 (n=1934) in 2019 and 194.0/100.000 (n=1821) in 2020 among adults of UB city. The
above results were compared to 1998-1999 studies and the incidence rate declined by 94.0/100.000
in 2019-2020, whereas mortality rate increased by 10.0/100.000 in women aged 16-34. Stroke
mortality was 11.6% in 1998 and 26.5% in 1999, while in our study it was 33.87% in 2019 and 29.71%
in 2020. Although the incidence of stroke rates has decreased in 1998-1999, the mortality rate has
not decreased significantly.
Conclusion:Morbidity and mortality rates among the population of Ulaanbaatar citizen remain
highest in the world, compared to 20 years ago with overall morbidity declining but mortality has not
decreased.
In recent years, the Government of Mongolia has been focused on reducing non-communicable
diseases, but the primary and secondary prevention and control of stroke in the general population,
as well as the acquisition of knowledge attitudes, practices and access to health care still need to be
improved.
