[Dynamic analysis of incidence and mortality of stroke and the risk factors in the communities in Shanghai, in the 1990's].
OBJECTIVE
To understand the trend of incidence, mortality of stroke and the risk factors at the community level in the 1990's.


METHODS
To establish a network of disease surveillance. Both incidence and mortality of stroke were surveyed in the 35 - 74 age group during 1991 - 1999 using the method of WHO MONICA. By cluster sampling in 1992 and 1998, 500 individuals aged 35 - 59 from each female and male group were investigated respectively on the risk factor of stroke.


RESULTS
The incidence of stroke was averaged 168.2 per 100 000 in the group aged 35 - 79 during 1991 to 1999 with 194.5 and 144.9 pre 100 000 respectively for the male and female group of this age. The incidence of stroke in the male group was higher than that in the female group, also with a faster speed of increase in the male group. The overall mortality of stroke was averaged 79.2 per 100 000 with 87.2 and 71.4 per 100 000 in male and female groups respectively of this age group. The incidence of stroke increased with age in both male and female groups. The average age of onset had been 66.1 year olds during 1996 - 1999, 3.5 years older than that age groups during 1991 - 1995, but did not show much difference between male group and female group. CHO, Blood Pressure, BMI, Prevalence of Hypertension, TC/HDLC, WHR, Prevalence of High-CHO, Prevalence of Low-HDL all had a tendency of increase in both male and female groups. The rates of smoking cigarettes and drinking alcohol both decreased, especially in the male group.


CONCLUSIONS
The incidence of stroke and some relative risk factors seemed to increase in the 1990's, but the mortality of stroke had a decrease in the same period in the communities in Shanghai.
