title: [Changes of mortality rate for cervical cancer during 1970's and 1990's periods in China].
abstract: OBJECTIVE
  To describe the distribution changes of the mortality rate for cervical cancer in China between the 1970's and 1990's and provide the scientific evidence for the prevention and control strategies for cervical cancer campaign in China between next century.
  
  
  METHODS
  Data from two National Surveys for the Causes of Death in 1970's and 1990's in China. The crude and adjusted mortality rates for the cervical cancer and the distributions based on age and area were calculated and described. The comparison of the differences of changes between two mortality rates periods and together with its trends were shown based on the age-standardized.
  
  
  RESULTS
  During two decades, the mortality rate for cervical cancer was 10.7 per 100,000 in 1970's which declined to 3.89 per 100,000 in 1990's, and from the 3rd ranking among all female malignant tumors to the 6th in 1990's (decreased about 63.64%). But the declination was not evenly. There have still been some high-risk areas, most located in rural countries in the mid-west of China, with rates remain unchanged and even at the highest level in the world, such as Wudu in Gansu and Yangcheng in Shanxi. A big difference was showed between rural country and city, but in both of them, the mortality rates in 1990's were significantly much lower than in 1970's (P = 0.001) at each five-year age group. And in the city, there was a much sharper increased trend in young women in 1990's.
  
  
  CONCLUSIONS
  The mortality rate for cervical cancer campaign in China has been substantially declined during past twenty years, but it's still a major health problem for women, especially in rural China. The focus of the prevention and control for the cervical cancer in the next century should put on rural areas, especially in mid-west of China and young women in the city.
