Determinants and Time Trends for Ischaemic and Haemorrhagic Stroke in a Large Chinese Population

The clinical epidemiology of stroke has been widely investigated in Caucasian populations, but the changes over time in the proportion of ischaemic to haemorrhagic strokes is less clear, especially in the Chinese population. Our objective was to study the determinants and time trends for ischaemic a...

Description
Summary:The clinical epidemiology of stroke has been widely investigated in Caucasian populations, but the changes over time in the proportion of ischaemic to haemorrhagic strokes is less clear, especially in the Chinese population. Our objective was to study the determinants and time trends for ischaemic and haemorrhagic stroke, in relation to age, in a large Chinese population cohort. Using a medical insurance database in the southwest of China from 2001 to 2012, time trends in age-adjusted ischaemic and haemorrhagic stroke incidence and the contributing risk factors associated with age were investigated. Among 425,901 individuals without prior stroke (52.4% male, median age 54), the rate of ischaemic stroke (per 1000 patient-years) decreased between 2002-2007, then remained broadly similar between 2008-2012. The rate of haemorrhagic stroke showed a similar trend, being approximately 1.3-1.9 from 2008-2012. Compared to patients age
