Developmental and Comparative Survey of Hypertension Prevalence Rate in Shanghai Urban and Rural Populations

Zhao Guangsheng ,et alShanghai Institute of Hypertension,Rui-Jin Hospital affliated to Shanghai Medical University,Shanghai, 200025  
According to the nation ?wide uniform standard and method, hypertension prevalence rates (P. R) of 21189 adults (above 15 years) were examined in 3 urban and 3 rural populations screening at random in shanghai. The adjusted rate of response was 91. 85%. Result showed: (1)The borderline, established and pooled (borderline + established)P. R. were 6. 38%,6. 31%, 12. 69% respectively; the standarized P. R. in urban and rural were 11. 05%,6. 59% ;the ages of abrupt rise of P. R. was 5 years early in urban and the urban-rural P. R. and blood pressure level difference were 10~15 years. (2)The P. R. washigher before 55 years in male,while after 65 contrailyiblood pressurel-erels were higher in urban than rural in males after 40 and in female after 45 years,no urban-rural difference before 40 in male while it was higher in rural females contraily. (3) The pooled stand arized P. R. in urban were not different in comparison with that of 1979, while the rural P. R. was 181. 04% to that of 1979 and the age of abrupt rise of P. R. in rural during this survey was 5 years early. The increment of 28. 91% of P. R. than that of 1979 was mainly due to the tremendous rise of P. R. of borderline cases in rural and the difference of urban-rural standarized P. R. was thus droped from 2. 2 fold during 1979 to only o. 68 fold during this survey. Daily life and work, social psychology , and modes of life and relation to their environment were changed enormously in rural since 1979. To search for the exact cause of abrupt decreae of the urban-rural P. R. difference and take somewhat effective approaches preventing the blood pressure rise due to the guickness of modernization might be an urgent neces sary just now .
